Microsatellite Instability And Allelic Imbalance In Primary And Secondary Colorectal Cancer

ANZ JOURNAL OF SURGERY, Issue 8 2000
Anne Schneider
Background: Several studies of colorectal cancer have shown an association between the number and type of genomic defects and the stage of disease. A subset of colorectal tumours are due to inactivation of DNA mismatch repair genes and these tumours exhibit microsatellite instability. The aim of the present study was to compare and contrast the genomic defects present in both the primary and metastatic stages of the disease using microsatellite probes. Methods: Modifications of the allelic profiles of 25 microsatellite regions were studied in a total of 85 colorectal tumours using fluorescent polymerase chain reaction (PCR) technology and subsequent direct analysis on an automatic sequencer. This approach was used because it allows the study of microsatellite instability and allelic imbalance. Stepwise logistic regression analysis was used to develop a model to predict whether the tumour was primary or secondary from the percentage of allelic imbalance. Subsequently, a group of 17 patients with primary colorectal tumours was analysed prospectively to test the proposed model. Results: Six of 39 primary tumours showed microsatellite instability compared to 0 of 29 liver metastases (P = 0.03). Primary tumours showed significantly less allelic imbalance than liver metastases (P < 0.001). Three probes (d18s53, d9s158 and d10s191) were selected for use in a model to classify a tumour as primary or secondary on the basis of the degree of allelic imbalance. When tested prospectively this model had a specificity of 82%. Conclusions: The present study demonstrates the potential importance of using microsatellite probes both as a diagnostic tool and as a research technique to investigate the mechanisms of tumour progression. An important clinical finding is that none of the colorectal liver metastases showed microsatellite instability (0 of 29). This analysis also confirmed other work that has shown a direct relationship between the degree of allelic imbalance and the stage of disease. [source]


Classification, incidence and survival analyses of children with CNS tumours diagnosed in Sweden 1984,2005

ACTA PAEDIATRICA, Issue 10 2009
Birgitta Lannering
Abstract Aim:, Primary tumours in the central nervous system (CNS) are the second most common malignancy in childhood after leukaemia. Sweden has a high incidence and a high-survival rate in international comparative studies. This has raised the question about the type of tumours included in the Swedish Cancer registry. We therefore compared international data to the Swedish Childhood Cancer registry. Methods:, Central nervous system tumours registered in the Swedish Childhood Cancer Registry were reclassified according to ICCC-3. Incidence and survival analyses were performed in the study population. Results:, There were 1479 children (<15 years) in Sweden diagnosed with CNS tumours 1984,2005. The distribution of diagnoses was similar to that reported in other studies. The annual incidence was 4.2/100 000 children. The survival rates have not improved significantly between the two time periods before/after 1995 (70% vs. 74%; p = 0.10). Conclusions:, The mean annual incidence of children with CNS tumours was 4.2/100 000 and has not increased during the study period. Survival rate for brain tumours at 10 years follow-up was 72%.

Uncertainty, lack of control and emotional functioning in women with metastatic breast cancer: a review and secondary analysis of the literature using the critical appraisal technique

EUROPEAN JOURNAL OF CANCER CARE, Issue 5 2010
M. WARREN msc, clinical nurse specialist
WARREN M. (2010) European Journal of Cancer Care19, 564,574 Uncertainty, lack of control and emotional functioning in women with metastatic breast cancer: a review and secondary analysis of the literature using the critical appraisal technique A diagnosis of metastatic (or secondary) breast cancer is frequently more distressing than the diagnosis of a primary tumour since it indicates that the cancer is no longer curable. Relatively little is known, however, about women's experiences of this condition in comparison with those diagnosed with primary breast cancer. This paper therefore reports findings from a secondary analysis of the published literature on the topic using tools from the critical appraisal skills programme to identify and analyse appropriate papers, and the constant comparative method as a means of identifying any overarching or dominant themes emerging from the literature. Uncertainty, lack of control and poor emotional functioning emerged as the main themes affecting women with metastatic breast cancer. These are discussed in relation to their antecedents in the original studies and their implications for nursing care. The themes demonstrate that living with metastatic (or secondary) breast cancer is a multifaceted experience that is influenced by a large number of factors, many of which are under-researched in comparison with those affecting women diagnosed with primary disease. It is clear, however, that women affected by the condition need a great deal more support than they currently receive, and new services may be required to meet these needs. [source]


New pharmacological strategies against metastatic spread

FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2008
G.Y. Perret
Abstract Although metastatic spread is the most frequent cause of death in cancer patients, there are very few drugs specifically targeting this process. Bases for a new antimetastatic drug discovery strategy are weak because a great number of unknowns characterize the complete understanding of the metastatic cascade mechanisms. Moreover, the current experimental models are too simplistic and do not account for the complexity of the phenomenon. Some targets have been identified but too few are validated. Among them, the metastasis suppressor genes seem to be the most promising. In spite of this, during recent years, a dozen of molecules, which fulfil the definition of a specific metastatic drug that inhibits the metastases without altering the growth of the primary tumour (which can be eradicated by surgery), have been identified and assessed for the proof of the concept. The continuation of this effort would benefit in terms of efficiency, if the objectives were defined more precisely. It is particularly important to distinguish molecules that prevent spread of the metastatic cells of the early-stage primary tumour from the ones which induce a regression of the established metastases or to inhibit the transition from disseminated occult tumour cells to dormant micrometastasis. This second goal is a priori more relevant in the current clinical setting where the detection of early metastatic spread is very difficult, and therefore would call for greater effort on the part of the scientific community.

Prognostic factors in lymph node metastases of prostatic cancer patients: the size of the metastases but not extranodal extension independently predicts survival

HISTOPATHOLOGY, Issue 4 2008
A Fleischmann
Aims:, To analyse tumour characteristics and the prognostic significance of prostatic cancers with extranodal extension of lymph node metastases (ENE) in 102 node-positive, hormone treatment-naive patients undergoing radical prostatectomy and extended lymphadenectomy. Methods and results:, The median number of nodes examined per patient was 21 (range 9,68), and the median follow-up time was 92 months (range 12,191). ENE was observed in 71 patients (70%). They had significantly more, larger and less differentiated nodal metastases, paralleled by significantly larger primary tumours at more advanced stages and with higher Gleason scores than patients without ENE. ENE defined a subgroup with significantly decreased biochemical recurrence-free (P = 0.038) and overall survival (P = 0.037). In multivariate analyses the diameter of the largest metastasis and Gleason score of the primary tumour were independent predictors of survival. Conclusions:, ENE in prostatic cancer is an indicator lesion for advanced/aggressive tumours with poor outcome. However, the strong correlation with larger metastases suggests that ENE may result from their size, which was the only independent risk factor in the metastasizing component. Consequently, histopathological reports should specify the true indicator of poor survival in the lymphadenectomy specimens, which is the size of the largest metastasis in each patient. [source]


Cyclooxygenase-2 expression correlates with phaeochromocytoma malignancy: evidence for a Bcl-2-dependent mechanism

HISTOPATHOLOGY, Issue 6 2007
I S Cadden
Aims:, Phaeochromocytomas are rare but potentially life-threatening neuroendocrine tumours of the adrenal medulla or sympathetic nervous system ganglia. There are no histological features which reliably differentiate benign from malignant phaeochromocytomas. The aim of the study was to evaluate cyclooxygenase (COX)-2 and Bcl-2 as tissue-based biomarkers of phaeochromocytoma prognosis. Methods and results:, COX-2 and Bcl-2 expression were examined immunohistochemically in tissue from 41 sporadic phaeochromocytoma patients followed up for a minimum of 5 years after diagnosis. There was a statistically significant association between COX-2 histoscore (intensity × proportion) and the development of tumour recurrence or metastases (P = 0.006). A significant relationship was observed between coexpression of COX-2 and Bcl-2 in the primary tumour and the presence of recurrent disease (P = 0.034). A highly significant association was observed between (i) tumour-associated expression of these two oncoproteins (P = 0.001) and (ii) COX-2 histoscore and the presence of Bcl-2 expression (P = 0.002). COX regression analysis demonstrated no significant relationship between (i) the presence or absence of either COX-2 or Bcl-2 and patient survival or (ii) COX-2 histoscore and patient survival. Conclusions:, COX-2 and Bcl-2 may promote phaeochromocytoma malignancy, and these oncoproteins may be valuable surrogate markers of an aggressive tumour phenotype. [source]


Extraskeletal osteosarcoma located to the gallbladder

HPB, Issue 1 2006
GÁBOR OLGYAI
Abstract Extraskeletal osteosarcoma is a rare malignant soft tissue tumour. At open cholecystectomy performed for gallstones, a 61-year-old woman was found to have osseous tissue in the wall of the gallbladder. Histopathological examination of the specimen revealed a focus of extraskeletal osteosarcoma. The patient developed widespread intra-abdominal metastases 5 months after the operation, and died of pulmonary deposits at 9 months. Although osteosarcoma has rarely been reported at other extraskeletal sites, this appears to be the first case of a primary tumour in the gallbladder. [source]


JKT-1 is not a human seminoma cell line

INTERNATIONAL JOURNAL OF ANDROLOGY, Issue 4 2007
Jeroen de Jong
Summary The JKT-1 cell line has been used in multiple independent studies as a representative model of human testicular seminoma. However, no cell line for this specific tumour type has been independently confirmed previously; and therefore, the seminomatous origin of JKT-1 must be proven. The genetic constitution of the JKT-1 cells was determined using flow cytometry and spectral karyotyping, as well as array comparative genomic hybridization and fluorescent in situ hybridization. Marker profiling, predominantly based on differentially expressed proteins during normal germ cell development, was performed by immunohistochemistry and Western blot analyses. Moreover, genome wide affymetrix mRNA expression and profiling of 157 microRNAs was performed, and the status of genomic imprinting was determined. A germ cell origin of the JKT-1 cells was in line with genomic imprinting status and marker profile (including positive staining for several cancer-testis antigens). However, the supposed primary tumour, from which the cell line was derived, being indeed a classical seminoma, was molecularly proven not to be the origin of the cell line. The characteristic chromosomal anomalies of seminoma, e.g. gain of the short arm of chromosome 12, as well as the informative marker profile (positive staining for OCT3/4, NANOG, among others) were absent in the various JKT-1 cell lines investigated, irrespective of where the cells were cultured. All results indicate that the JKT-1 cell line is not representative of human seminoma. Although it can originate from an early germ cell, a non-germ cell derivation cannot be excluded. [source]


Biological characteristics of breast cancer at the primary tumour and the involved lymph nodes

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 9 2005
E. Dikicioglu
Summary Diminished oestrogen receptor (ER) expression in the involved axillary lymph nodes (ALN) in breast cancer compared with the primary tumour has been reported in previous studies. We have assessed a wider spectrum of tumour markers (ER, progesterone receptor (PgR), p53, Ki-67 and HER-2/neu) and compared extent and staining intensities at the primary tumour and the involved ALN on specimens of 22 cases with invasive ductal breast cancer. At the involved ALN, both the quantity of positive staining cells and the staining intensities for ER and PgR were decreased (p < 0.001 and p = 0.003, respectively). In contrast, the quantity of positive staining cells (p < 0.004) and the staining intensities for Ki-67 were increased. The differences for HER-2/neu and p53 staining at both sites were insignificant. The immunohistochemical staining properties of both the primary tumour and the ALN metastases showed no correlation with the number of involved ALN (p > 0.05). This study suggested that ALN metastasis might indicate a more unfavourable expression pattern of ER, PgR and Ki-67 in invasive ductal breast cancer. [source]


Cutaneous metastasis from a parotid myoepithelial carcinoma: a case report and review of the literature

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 12 2008
Deng-qi He
Myoepithelial carcinoma of the parotid gland is a rare salivary gland tumour, and its distant cutaneous metastasis has not been reported to date. Here, we report a case of myoepithelial carcinoma of the left parotid gland, which had metastasised to the skin of the right thorax after parotidectomy and radiotherapy. Diagnosis of the primary and metastatic tumour was based on the clinical findings and was confirmed by immunohistochemistry. A literature review of the clinical features of the skin metastases of parotid malignancies and their related pathological mechanisms is included in this case study. It was noted that myoepithelial carcinoma of the parotid gland has the potential to develop distant skin metastasis, which may be indicative of widespread dissemination and poor prognosis. Attention should be paid to initial treatment of the primary tumour and to emerging cutaneous masses whose location is distant from the primary tumour during follow up. [source]


Standardised tumour, node and metastasis reporting of oncology CT scans

JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 4 2009
KLM Gormly
Summary The oncology CT report is a vital piece of communication between the radiologist and the treating clinician and often determines patient management. The use of a standardised report that follows the tumour, node and metastasis (TNM) structure makes it easier for the radiologist to include all of the necessary information in an easy-to-read format. Presenting the results under the headings of primary tumour, lymph nodes, metastases, and other findings follows a similar pattern to that used by pathologists and also follows the thought process of the treating clinician. Standardised templates for TNM-based oncology CT reports were introduced into public and private institutions. An audit of 199 reports demonstrated a significant increase in the presence of measurements and conclusions in the template reports. While there was a non-significant increase in the use of correct Response Evaluation Criteria In Solid Tumours terminology for template reports, there was an improved attempt to describe the disease response. Saving measurements as a summary series on PACS also assists follow-up reporting. [source]

Type II nitric oxide synthase (NOS2) expression correlates with lymph node status in oral squamous cell carcinoma

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 3 2001
Peter A. Brennan
Abstract: In tumour biology, nitric oxide (NO) has a complex array of concentration-dependent actions, including both inhibitory and promoting effects. It is thought that the levels of NO found in many human cancers lead to enhanced angiogenesis and tumour dissemination. In the current study, we assessed the immunohistochemical expression of the enzyme type II nitric oxide synthase (NOS2) in 41 cases of oral squamous cell carcinoma and correlated the findings with lymph node status. A significant relationship was found between NOS2 expression and lymph node metastasis (P<0.0002). Furthermore, lymph node metastasis correlated with the degree and intensity of staining seen (P<0.001). No correlation was found between the size of the primary tumour, degree of tumour differentiation or smoking status and NOS2 staining. Western blotting confirmed NOS2 protein expression in select cases. As with many other human tumours, NOS2 is not a ubiquitous finding in oral cancer. Its expression may be of value in assessing lymph node status prior to surgery, and it represents a target for possible therapeutic manipulation. [source]


Sentinel lymph node as a new marker for therapeutic planning in breast cancer patients

JOURNAL OF SURGICAL ONCOLOGY, Issue 3 2004
Marco Gipponi MD
Abstract Background and Objectives Literature review suggests that the sentinel lymph node (sN) represents a reliable predictor of axillary lymph node status in breast cancer patients; however, some important issues, such as the optimisation of the technique for the intraoperative identification of the sN, the role of intraoperative frozen section examination of the sN, and the clinical implications of sN metastasis as regards the surgical management of the axilla, still require further confirmation. The authors aimed (1) to assess the feasibility of sN identification with a combined approach (vital blue dye lymphatic mapping and radioguided surgery, RGS) and the specific contribution of either techniques to the detection of the sN, (2) to determine the accuracy and usefulness of intraoperative frozen section examination of the sN in order to perform a one-stage surgical procedure, and (3) to define how the sN might modulate the therapeutic planning in different stages of disease. Materials and Methods From October 1997 to June 2001, 334 patients with early-stage (T1,2 N0 M0) invasive mammary carcinoma underwent sN biopsy; the average age of patients was 61.5 years (range, 39,75 years). In a subset of 153 patients, both vital blue dye (Patent Blue-V) lymphatic mapping and RGS were used to identify the sN, and the relative contribution of each of the two techniques was assessed. Results In the whole group, the sN was identified in 326 of 334 patients (97.6%), and 105 of 326 patients (37.3%) had positive axillary lymph nodes (pN+). In 9 of 105 pN+ patients, the definitive histologic examination of the sN did not show metastases but these were detected in non-sN, thus giving an 8.6% false-negative rate, a negative predictive value of 94.5% (156/165), and an accuracy of 96.5% (252/261). As regards the specific contribution of the two different techniques used in the identification of the sN, the detection rate was 73.8% (113/153) with Patent Blue-V alone, 94.1% (144/153) with RGS alone, and 98.7% (151/153) with Patent Blue-V combined with RGS (P,<,0.001). Noteworthy, whenever the sN was identified, the prediction of axillary lymph node status was remarkably similar (93,95% sensitivity; 100% specificity; 95,97% negative predictive value, and 97,98% accuracy) whichever of the three procedures was adopted (Patent Blue-V alone, RGS alone, or combined Patent Blue-V and RGS). Intraoperative frozen section examination was performed in 261 patients, who had at least one sN identified, out of 267 patients who underwent complete axillary dissection; 170 patients had histologically negative sN (i.o. sN,) and 91 patients histologically positive sN (i.o. sN+). All 91 i.o. sN+ were confirmed by definitive histology, whereas in 14 of 170 i.o. sN, patients (8.2%) metastases were detected at definitive histology. As regards the correlation between the size of sN metastasis, the primary tumour size, and the status of non-sN in the axilla, micrometastases were detected at final histology in 23 patients and macrometastases in 82 patients. When only micrometastases were detected, the sN was the exclusive site of nodal metastasis in 20 of 23 patients (86.9%) while in 3 patients with tumour size larger than 10 mm micrometastases were detected also in non-sN. Macrometastases were never detected in pT1a breast cancer patients; the sN was the exclusive site of these metastases in 30 patients (36.6%), while in 52 patients (63.4%) there were metastases both in sN and non-sN. Conclusions Sentinel lymphadenectomy can better be accomplished when both procedures (lymphatic mapping with vital blue dye and RGS) are used, because of the significantly higher sN detection rate, although the prediction of axillary lymph node status remains remarkably similar whichever method is used. The intraoperative frozen section examination proved to be rather accurate in predicting the actual pathologic status of the sN, with a negative predictive value of 91.8%; in 35% of patients it allowed sN biopsy and axillary dissection to be performed in a one-stage surgical procedure. Finally, specific clinical and histopathologic features of the primary tumour and sN might be used to tailor the loco-regional and systemic treatment in different clinical settings, such as in ductal carcinoma in-situ (DCIS), early-stage invasive breast cancer, and patients with large breast cancer undergoing neo-adjuvant CT for breast-saving surgery as well as elderly patients with operable breast cancer.

Possible role of dermoscopy in the detection of a primary cutaneous melanoma of unknown origin

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 3 2006
M Stante
Abstract For 2,8% of patients with metastatic melanoma, cutaneous and mucosal clinical examination does not lead to diagnosis of the primary tumour, which remains unknown. We report the case of a 41-year-old male patient who had received a diagnosis of metastatic melanoma after histological examination of an enlarged axillary lymph node, without previous detection of the primary lesion at his first dermatological examination. No pigmented skin lesions located in the anatomical area potentially drained by the affected axillary basin showed clinical features suggestive of a melanoma. Neither did the so-called ,ugly duckling' sign help us to identify the melanoma, because of the presence of a large number of clinically similar, common or slightly atypical melanocytic lesions located in that area. After dermoscopic examination we were able to narrow the field of possible candidates for excision to four lesions, selected on the basis of their dermoscopic features. Histological examination revealed the primary melanoma (superficial spreading melanoma (SSM), level III, thickness 0.5 mm) , located on the back , and three naevi with atypia. Preoperative distinction of the melanoma from the other three lesions was not possible because of the lack of well-established features of malignancy, even at dermoscopic analysis (,featureless' melanoma). Dermoscopy may thus play a role in the detection of a clinically unknown primary melanoma by narrowing the field of lesions to be removed for histological examination, saving many unnecessary excisions that would otherwise be inevitable.

Clinical and biological significance of CXCL12 and CXCR4 expression in adult testes and germ cell tumours of adults and adolescents,

THE JOURNAL OF PATHOLOGY, Issue 1 2009
DC Gilbert
Abstract Interaction between the chemokine CXCL12 (SDF1) and the G-protein coupled receptor CXCR4 is responsible for the maintenance of adult stem cell niches and is known to play an important role in utero in the migration of primordial germ cells. We demonstrate expression of CXCL12 by Sertoli cells and confirm CXCR4 expression by the germ cell population of the adult human testes. CXCR4 is also known to mediate organ-specific patterns of metastases in a range of common cancers. We identify consistent expression of CXCR4 mRNA and protein in testicular germ cell tumours (TGCT) that accounts for their patterns of relapse in sites of known CXCL12 expression. Extragonadal primary germ cell tumours express CXCR4 and their sites of occurrence are coincident with areas of known CXCL12 expression in utero. We show that CXCL12 stimulates the invasive migration of a TGCT cell line in vitro in a CXCR4-dependent fashion and activates ERK. Furthermore, we demonstrate that expression of CXCL12 in stage I non-seminomas is significantly associated with organ-confined disease post-orchidectomy and reduced risk of relapse (p = 0.003). This may be through the loss of CXCL12 gradients that might otherwise attract cells away from the primary tumour. We propose CXCL12 expression as a potential predictor of subsequent relapse that could lead to avoiding unnecessary treatment and associated late toxicities. Our observations support a role for CXCL12/CXCR4 in the adult germ cell population and demonstrate pathological function in germ cell tumour development and metastasis that may have clinical utility.

Metastatic myoepithelioma of the breast

ANZ JOURNAL OF SURGERY, Issue 12 2004
Ross R. Jennens
Myoepitheliomas are typically benign tumours arising from exocrine glands. There have only been five reports of malignant myoepitheliomas from breast origin previously published in the English literature. This report describes a patient with myoepithelioma arising in the breast which later metastasized despite the primary tumour having benign histological features. Impaired immune function due to end-stage renal failure and haemodialysis may have contributed to the malignant potential of her tumour. The literature regarding myoepithelial tumours is reviewed. All breast myoepitheliomas should be managed as potentially malignant tumours with appropriate surgical clearance and staging. [source]


Lymph node metastasis of gastric cancer: comparison of Union International Contra Cancer and Japanese systems

ANZ JOURNAL OF SURGERY, Issue 10 2004
Masahide Ikeguchi
Background: The pN classification of gastric cancer (GC) in the Japanese system (Japanese Gastric Cancer Association; JGCA) is based on the site and distance of metastatic nodes from the primary tumour. Union International Contra Cancer (UICC) has recently proposed a classification system based on the number of nodes involved (TNM-1997). The aim of the present study is to assess which classification system is more suitable for providing a prognosis in advanced GC with lymph node metastasis. Methods: A total of 224 patients who underwent curative gastrectomy (R0: UICC,TNM and Resection A and B: JGCA) and D2 lymphadenectomy between 1990 and 1999, and diagnosed as pT2, pT3 and pT4 GC were enrolled. Patients were followed until the end of 2002. The disease-free survival rates of patients were compared between the two-stage systems (UICC,TNM and JGCA). Results: Using the JGCA system, there was a significant difference between the two survival curves (pN0 and pN1, P = 0.025; pN1 and pN2, P < 0.001; pN2 and pN3, P = 0.031), but the 5-year survival rate of 27 pN2 patients (32.7%) was not significantly different from that of 14 pN3 patients (34.3%, P = 0.994) using the UICC,TNM. In 47 patients with JGCA pN2, the 5-year survival rate of 18 patients with UICC,TNM pN1 (42.9%) was not significantly different from that of 18 patients with UICC,TNM pN2 (25.2%, P = 0.422) or from that of 11 patients with UICC,TNM pN3 (24.2%; P = 0.383). Conclusions: The JGCA system is more suitable for estimating the prognosis of Japanese patients with advanced GC than the UICC,TNM. [source]


Is palliative resection of the primary tumour, in the presence of advanced rectal cancer, a safe and useful technique for symptom control?

ANZ JOURNAL OF SURGERY, Issue 4 2004
Nasser Al-Sanea
Introduction: At some time, every general surgeon will be faced with the task of trying to decide what to do with a patient who presents with rectal cancer and unresectable distant metastases. How safe is resectional surgery? What sort of palliation may be expected following resection of the primary tumour? In an attempt to answer these questions, the management and outcomes of all patients with rectal cancer and distant metastases, who were primarily referred to the colorectal unit at King Faisal Specialist Hospital were examined. Methods: All patients who underwent primary surgery for rectal cancer in the presence of metastatic disease were identified. The charts of these patients were examined and their morbidity, mortality and survival were determined. Results: Over an 8-year period 22 patients (average age 54 years) underwent rectal resectional surgery in the presence of metastatic disease. There were 13 men and nine women. The commonest complaint was rectal bleeding. All patients had chest radiographs. Pulmonary metastases were identified in four patients. Nineteen abdominal and pelvic computed tomography scans were performed and eight showed evidence of metastases. Skeletal radiographs in two patients showed evidence of bone metastasis. At operation, intraperitoneal metastases were found in 18 patients. Nine of these were not identified preoperatively. Six patients underwent abdomino-perineal resection, nine anterior resection and seven a Hartmann's procedure. Eight patients developed a significant postoperative complication and one died 42 days after surgery. The mean length of hospital stay was 18.6 days. Nine patients received preoperative radiotherapy. Four patients had palliative radiotherapy, two for bony, one for liver and one for peritoneal metastases. Patients were followed up for a mean of 1.1 years. During follow up, 11 returned to the emergency room on 24 occasions. Two patients required readmission. No patient had further rectal bleeding. The mean survival was 1.3 years. Conclusion: Patients with rectal cancer and unresectable distant metastases can be successfully palliated by resection of the primary tumour with low morbidity and mortality. The early involvement of a palliative care team facilitates patient management and helps patients enjoy what remains of the rest of their lives at home, in comfort and with good symptom control.

Secondary breast cancer: a 5-year population-based study with review of the literature

APMIS, Issue 10 2009
TOR AUDUN KLINGEN
Secondary tumours in the breast are rare. Based on literature, an incidence of 0.4,2% is reported. In this population-based study, secondary breast tumours from a 5-year period (2001,2005), not including metastasis from contralateral breast carcinoma, were reviewed (Vestfold County, Norway). A total of 722 patients with breast malignancies were found in this population (89.3% from Vestfold County Hospital). Ten of these, approximately 1.4%, were metastatic tumours, representing four cutaneous melanomas, three pulmonary carcinomas and three malignant lymphomas. The tumours were often solitary, palpable and close to the skin. Radiologically, the lesions mostly resembled primary carcinomas by mammography and ultrasound, which differs from other studies. Comparison with a known primary tumour and use of immunohistochemical profiling is of crucial importance. Melanoma markers (Melan-A, HMB-45, S-100 protein), lung cancer markers (Cytokeratins, TTF1, Chromogranin, Synapthophysin) and lymphoid markers (CD3, CD20) usually help to confirm a secondary breast tumour diagnosis. This approach is especially indicated in diffusely growing tumours with lack of glandular structure and high-grade cytological features, and staining for ER and GCDFP15 may be helpful. Thus, the diagnosis of a breast metastasis may be suspected by careful mammography and ultrasound imaging, although some cases have atypical radiological features, and histological examination might be necessary to ensure a correct diagnosis and appropriate treatment.

ABSTRACT Metastatic Merkel cell carcinoma uncommonly presents with an unidentified primary tumour. We report a patient who first presented with lichenoid dermatitis and was found to have Merkel cell carcinoma involving lymph nodes with an unknown primary site. With the rising incidence of Merkel cell carcinoma, it is important to recognize unusual manifestations of this disease as they may become more common in the future. [source]


Making use of the primary tumour

BIOESSAYS, Issue 1 2003
Arnold Baars
Surgical resection of a primary tumour is often not sufficient to cure a patient. Even when no residual cancer can be detected at time of surgery, metastases may appear in the following years, which indicates that the primary tumour had apparently spread before surgery. Following surgery, systemic chemotherapy may be used to eradicate micro-metastatic disease. Here we present two unconventional strategies that implement new insights into tumour biology and tumour immunology in the treatment of patients with cancer. Both experimental strategies use the individual characteristics of the patient's primary tumour to optimise the control of life-threatening micro-metastases. We aim to modulate the patient's adaptive immune system, targeting it towards the patient's own tumour cells to eradicate residual disease following local treatment. In one approach, this is done by autologous tumour cell vaccinations as adjuvant treatment for colon cancer patients and, in a second approach, by giving chemo-imunotherapy before local treatment to women with locally advanced breast cancer.

Objective Prognostic evaluation of HPV-16 genome status of the pelvic lymph nodes, the integration status of HPV-16 and p53 codon 72 polymorphism in cervical cancer. Design Prospective cohort study. Setting Department of Gynaecological Oncology, University of Debrecen, Hungary. Sample Thirty-nine patients with HPV-16 positive cervical cancer. Methods Primary tumour specimens of 39 cervical cancer patients with HPV-16 positive primary tumour were subjected to multiplex polymerase chain reaction using HPV-16 E1/E2, E7 and p53 codon 72 allele-specific primers. Pelvic lymph nodes of the same patients were also tested for the presence of HPV-16 DNA and for its integration status using HPV-16 E7 and E1/E2 ORF specific primers, respectively. Main outcome measures Progression-free survival. Results Metastatic lymph nodes carried HPV-16 DNA more frequently than nodes with no evidence of disease (100.0% vs 35.7%, P= 0.001). Cases with HPV-16 positive nodes had higher recurrence rate than those with HPV-16 negative nodes (42.9% vs 11.1%, P= 0.009). There was no difference between cases with and without histologically proven nodal disease with regard to integration status of HPV-16 DNA in the primary tumour (integrated 90.9% vs 71.4%, episomal 9.1% vs 21.4%, mixed 0% vs 7.1%) and p53 codon 72 polymorphism (Arg/Arg 54.5% vs 67.9%, Pro/Pro 0 vs 7.1%, Arg/Pro 45.5% vs 21.4%). Conclusion Regardless of the presence of nodal metastasis, HPV-16 status of the nodes is a significant predictor of recurrent disease. HPV-16 integration status and p53 codon 72 genotype do not seem to have a bearing on disease outcome in cervical cancer with HPV-16 positive primary. [source]


Current status of metal stents for managing malignant ureteric obstruction

BJU INTERNATIONAL, Issue 8 2010
Petros Sountoulides
Obstruction of the ureters caused by extrinsic compression from a primary tumour or retroperitoneal lymph node masses is not unusual in the course of advanced pelvic malignancies. Most of the cases are of gynaecological or gastrointestinal origin, and the situation can be aggravated by peri-ureteric fibrosis, a long-term adverse event of previous chemotherapy or radiotherapy. Undoubtedly upper urinary tract decompression and maintenance of ureteric patency, even as a palliative measure, is important in managing these patients. Options for upper tract decompression include percutaneous nephrostomy, retrograde stenting and open urinary diversion. Plastic stents have long been used for managing malignant ureteric obstruction, but their overall success remains limited. Plastic stents often fail to be placed correctly, require regular exchange, and are faced with a high incidence of encrustation and migration. For these reasons plastic stents have been unsuccessful for long-term maintenance of ureteric patency. To overcome these limitations metal stents were introduced and recently developed in an effort to ensure better long-term patency of the obstructed ureter, fewer hospital admissions for stent change and better overall quality of life. In the present review the clinical applications of different types of metal stents are discussed, with a specific focus on the latest advances and the future options for managing malignant ureteric obstruction.

Analysis of HER2 expression in primary urinary bladder carcinoma and corresponding metastases

BJU INTERNATIONAL, Issue 7 2005

OBJECTIVE To evaluate the expression of HER2 receptors (previously reported to be over-expressed in malignant urothelium) in both primary tumours and metastases of transitional cell cancer, using two different staining methods and two different scoring techniques, considering the potential use of these receptors as targets for planned systemic anti-HER2 nuclide-based treatment. MATERIALS AND METHODS HER2 expression was evaluated with two different immunohistochemical methods in 90 patients with primary urinary bladder cancer tumours and corresponding metastases. Sections were first stained with the commercially available breast cancer test kit (HercepTest®, Dako, Glostrup, Denmark). Parallel sections were then stained with a modified HercepTest procedure. Two different evaluation criteria were compared; the HercepTest score that requires ,,10% stained tumour cells (as for breast cancer) and a proposed ,Target score' that requires >67% stained tumour cells. The latter score is assumed to be preferable for HER2-targeted radionuclide therapy. RESULTS Using the HercepTest kit, the Target score gave lower fractions of positive primary tumours and metastases than the HercepTest score. The modified HercepTest staining procedure and Target score gave high HER2 values in 80% of primary tumours and 62% of metastases, which is considerably more than that obtained with the HercepTest staining and score. There was a significant decrease in HER2 positivity with increasing distance from the primary tumour. In nine sentinel-node metastases assessed, all but one were HER2-positive. Considering all regional metastases, 74% were positive, and of distant metastases, 47%; 72% of the patients with positive primary tumours also expressed HER2 in their metastases. CONCLUSIONS When combining the modified HercepTest with customised evaluation criteria, more HER2-positive tumours were diagnosed. The degree of HER2 down-regulation was significantly higher in distant than in regional metastases. HER2-targeted therapy may be an alternative or complementary to other methods in the future treatment of metastatic urinary bladder carcinoma. [source]


Correlation between clinical and pathological staging in a series of radical cystectomies for bladder carcinoma

OBJECTIVE To analyse the rate of concordance between the clinical and pathological Tumour-Nodes-Metastasis staging systems in a homogeneous series of patients who had undergone radical cystectomy for locally advanced or recurrent multifocal superficial bladder carcinoma. PATIENTS AND METHODS The clinical data of 156 patients who had undergone radical cystectomy and bilateral iliaco-obturator lymphadenectomy for bladder cancer in our department were analysed retrospectively. RESULTS The clinical stage of the primary tumour was carcinoma in situ in three patients (1.9%), cT1 in 67 (42.9%), cT2 in 70 (44.9%), cT3 in five (3.2%) and cT4 in nine (5.8%). Clinical lymph node involvement was detected in 19 patients (12.2%). The differences between clinical and pathological stages were statistically significant (P < 0.001), the concordance was moderate (, = 0.27, P < 0.001). Of the 70 patients with ,,cT1, 40 (57%) were reconfirmed as having pathological stage ,,T1; of the 70 with cT2, 16 (23%) had pT2 carcinoma. Of the 140 patients with clinically organ-confined (,T2) neoplasms, 70 (50%) had been understaged after radical cystectomy. The clinical and pathological systems were statistically overlapping for locally advanced cases only. Pathological lymph node involvement was diagnosed in 45 patients (28.8%); this was foreseen with pelvic computed tomography in 19 (12%) only (P < 0.001). All patients designated cN+ were also pN+. CONCLUSION These data confirm the high risk of clinical understaging of both local extension of the primary tumour and lymph node involvement. [source]


Positron emission tomography for urological tumours

BJU INTERNATIONAL, Issue 2 2003
S.F. Hain
SUMMARY For urological tumours, positron emission tomography (PET) is currently most useful in testicular cancer. In patients with residual masses or raised marker levels after treatment, PET is both sensitive and specific for detecting recurrent disease, at suspected and unsuspected sites. Although fewer studies are available it also appears to be useful for staging at diagnosis, although this requires further investigation. Prostate cancer imaging has been more variable, with studies showing that PET cannot reliably differentiate between tumour and hypertrophy. It is not as good as a bone scan for defining bone metastases. In renal cancer, PET can be used to define the primary tumour, providing better staging of local recurrence than computed tomography (CT), and to define metastatic disease. There are few studies in bladder cancer, and despite excretion of the tracer via the bladder in early studies, it has better results than CT or magnetic resonance imaging for local staging; again it can detect metastases. Overall, the place of PET in urological tumours is developing, with the strongest areas undoubtedly being testicular and renal cancer. Tracers other than fluorodeoxyglucose are being examined and are providing further information. [source]


Outcome and survival with nonsurgical management of renal cell carcinoma

BJU INTERNATIONAL, Issue 7 2003
A.D. Baird
OBJECTIVE To document long-term survival in patients with renal cell carcinoma (RCC) in whom the primary tumour was left in situ and treatment limited to palliative and symptomatic measures. PATIENTS AND METHODS All patients with a diagnosis of RCC from January 1994 to January 1999 and in whom the primary tumour was left in situ were identified from hospital records (nine women and 16 men, mean age 69 years). The tumour stage was T1,T4. RESULTS The mean survival overall was 19.3 months; patients with locally advanced disease, i.e. stage , T3a, had a mean survival of 16.9 months. CONCLUSIONS There is renewed interest in the management of advanced RCC, with data supporting cytoreductive nephrectomy with systemic biological therapy. These results confirm that such patients with or without metastatic disease can survive for a considerable period with no aggressive surgical or systemic measures, and such intervention may offer no significant advantage in outcome and survival over supportive treatment alone.
