HARRY V.N., CUMMING G.P., NARAYANSINGH G.V., PARKIN D.E. & HAITES N.E. (2010) European Journal of Cancer Care19, 276,278 The genetic causes of the sequential occurrence of multiple primary malignancies in a young woman , 5 years on The finding of three primary gynaecological malignancies in a young woman attending our unit was documented in 2001. We provide an update on this report as new events have prompted further discussion on the role of clinical guidelines in cancer management. The discovery of a genetic predisposition demonstrates the need for multidisciplinary input and heightened awareness in similar cases while the importance of treating each patient as an individual is emphasized.

A population-based study of hairy cell leukemia in Israel

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 5 2006
Ora Paltiel
Abstract:,Objectives: Few population-based data exist on the incidence and prognosis of hairy cell leukemia (HCL). Our objectives were to study the effect of socio-demographic factors on this rare disease and the risk of second malignancies occurring in HCL patients. Methods: We measured crude and age-adjusted incidence rates of HCL based on reporting to the Israel Cancer Registry (ICR) 1991,2001. Using Kaplan,Meier and multivariate analysis, we assessed survival by gender, ethnicity and geographic region. We ascertained additional primary tumors reported in this population and calculated standardized incidence ratios (SIRs) for tumors reported after the diagnosis of HCL. Results: The ICR registered 147 cases of HCL among males and 34 in females between 1991 and 2001. Age-adjusted incidence rates were 1.62/106/yr for women and 7.97/106/yr for men, with rates 1.5 times higher in Jewish than in non-Jewish (mainly Arab) men. Mean overall survival also differed by ethnicity. In a multivariate model, increasing age at diagnosis (P < 0.001), as well as Arab origin (P = 0.008) were associated with poorer survival but gender did not significantly affect the survival after controlling for age and ethnicity. Other primary malignancies were reported in 20 (11%) individuals, with a predominance of genito-urinary tumors (65%) among males. Secondary genito-urinary tumors were significantly increased above the expected population rates (SIR 3.23, 95% confidence interval: 1.39,6.36, P = 0.008). Conclusions: In the Israeli population, age and ethnicity were associated with prognosis of HCL. Variations in disease characteristics, stage of disease at diagnosis or differential access to treatment may contribute to these findings. Patients with HCL appear to be at increased risk for genito-urinary malignancies. [source]

Head and neck cancer patients with pulmonary nodules: Value and role of CT-guided transthoracic needle aspiration biopsies

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 11 2003
Benoît Mesurolle MD
Abstract Background. To evaluate transthoracic needle aspiration biopsies of pulmonary lesions in patients with squamous cell cancer of head and neck. Methods. Retrospective series of 85 patients with squamous cell cancer of head and neck cancer and pulmonary nodules who underwent CT-guided needle aspiration biopsy. Results. Diagnostic samples were obtained in 85% of patients. There were 8 benign and 77 malignant lesions. Among the 73 proved cases, 4 were false-negative cases. CT-guided biopsy had an accuracy of 81%, a sensitivity of 94%, and a negative predictive value of 60%. Accuracies were 68% for lesions of 20 mm or smaller and 89% for lesions greater than 20 mm. In a subset of 45 solitary lesions, among 30 positive biopsies, 15 were categorized as primary malignancies, 3 as metastatic, and 12 as indeterminate malignancies. Conclusions. In head and neck cancer patients, the prevalence of thoracic malignancies is high when a pulmonary lesion is detected. CT-guided biopsy of pulmonary lesion is an accurate procedure. However, a third of positive biopsies were categorized as indeterminate malignancies. © 2003 Wiley Periodicals, Inc. Head Neck 25: 000,000, 2003 [source]

p73 G4C14-to-A4T14 polymorphism and risk of second primary malignancy after index squamous cell carcinoma of head and neck

INTERNATIONAL JOURNAL OF CANCER, Issue 11 2009

Abstract P73 plays an important role in modulating cell-cycle control, inducing apoptosis, and inhibiting cell growth. A novel noncoding p73 G4C14-to-A4T14 exon 2 polymorphism was associated with risk of squamous cell carcinoma of the head and neck (SCCHN). We hypothesized that p73 G4C14-to-A4T14 polymorphism modulates risk of second primary malignancies (SPM) in patients after index SCCHN. We followed a cohort of 1,384 patients diagnosed with incident SCCHN between May 1995 and January 2007 for SPM development. Log-rank test and Cox proportional hazard models were used to compare SPM-free survival and SPM risk between the different genotype groups. Our results showed that patients carrying the p73 variant AT allele were less likely to develop SPM compared with the patients with p73 GC/GC genotype (Log-rank test, p = 0.013). Compared with the p73 GC/GC genotype, there was a significantly reduced risk of SPM associated with the p73 GC/AT genotype (HR, 0.61, 95% CI, 0.40,0.93) and the combined p73 GC/AT+AT/AT genotypes (HR, 0.59, 95% CI, 0.39,0.89), but a nonsignificantly reduced risk for p73 AT/AT genotype (HR, 0.44, 95% CI, 0.14,1.41). The p73 AT allele was significantly associated with risk of SPM in an allele dose-response manner (p = 0.011 for trend). The risk of SPM associated with p73 variant genotypes (GC/AT+AT/AT) was more pronounced in several subgroups (e.g., older patients, men, minorities, ever smokers, and ever drinkers). Our results support that this p73 polymorphism may be a marker for risk of SPM among patients with an incident SCCHN. © 2009 UICC [source]

Concurrent diagnosis of urothelial carcinoma and squamous cell carcinoma of the bladder in a patient with a vesicorectal fistula from invasive rectal cancer

INTERNATIONAL JOURNAL OF UROLOGY, Issue 3 2006
KOICHI KODAMA
Abstract, A 47-year-old man underwent a low anterior resection of the rectosigmoid colon with en bloc cystoprostatectomy for vesicorectal fistula due to a locally advanced rectal cancer. Histopathological examination of the bladder revealed two additional primary malignancies: urothelial carcinoma and squamous cell carcinoma. To our knowledge, this is the first reported case of two histologically distinct urothelial malignancies that were diagnosed during a work up of vesicorectal fistula due to adenocarcinoma of the rectum.

Multiple primary malignancies in Spanish patients with hepatocellular carcinoma: Analysis of a hospital-based tumor registry

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 8 2009
Mario Fernández-Ruiz
Abstract Background and Aim:, Little is known about the etiological associations and clinical features of extrahepatic primary malignant (EHPM) neoplasms in subjects with hepatocellular carcinoma (HCC). The aim of this study was to characterize this phenomenon in a consecutive series of Spanish patients in order to define its natural history and influence on survival. Methods:, A retrospective analysis of 245 patients with HCC during the period 1999,2003 was performed. Subjects identified with a second primary malignancy elsewhere constituted the EHPM group and were compared to patients with HCC alone. Results:, Eighteen patients (7.3%) had one or two associated extrahepatic malignancies (mean age 67.7 ± 9.7 years); of these, 17 had double cancer and one patient, triple. Nine of the 19 EHPM occurred before HCC diagnosis. The associated cancers included five cases of colorectal carcinoma, four cases of head and neck carcinoma, three cases of genitourinary cancer, two cases of lymphoproliferative disorder, one lung carcinoma, one skin melanoma, one breast carcinoma, and two cancers of unknown origin. Age and sex distribution, etiology of underlying hepatopathy, and liver function tests did not differ significantly between both groups. There was no difference between the overall survival rates. Conclusions:, EHPM is not rare among Spanish patients with HCC, although no specific clinicopathological features were detected in this population. Our results suggest that the association of another primary tumor with HCC does not imply a worse prognosis. The possibility of development of EHPM should be kept in mind when deciding on therapy and follow-up of HCC. [source]

Malignancies of the Ear in Irradiated Patients of Nasopharyngeal Carcinoma

THE LARYNGOSCOPE, Issue 12 2008
Wu-Chia Lo MD
Abstract Objectives/Hypothesis: To report on the clinical profiles and treatment experiences of patients with second primary ear malignancy after treatment of nasopharyngeal carcinoma (NPC). Study Design: Retrospective case series. Methods: A retrospective review of the clinical outcomes and pathology of 11 irradiated NPC patients who subsequently had second primary malignancies of the ear at a single institution. Results: Ten tumors were squamous cell carcinoma and one tumor was chondrosarcoma occurring within the radiation field of previous treatment for NPC. The interval between previous radiotherapy and diagnosis of ear malignancy was 3 to 27 years with a median time of 17 years. Six tumors were located in the external auditory canal, two in the middle ear cavity, two in the periauricular region and one in the mastoid cavity. Four patients underwent surgery, and the other seven patients underwent surgery plus adjuvant radiotherapy. The 3-year disease-free and overall survival rates were 30.3% and 20%, respectively. Conclusions: Postirradiated malignancy of the ear is extremely rare, but is one of the causes of death for NPC long-term survivors despite curative-intended treatment with surgery plus adjuvant radiotherapy is instituted.

Role of fine-needle aspiration cytology in evaluation of cutaneous metastases

DIAGNOSTIC CYTOPATHOLOGY, Issue 12 2009
Sonal Sharma M.D.
Abstract Skin is an uncommon site for metastasis. This study was done to evaluate the role of FNAC as an important tool for investigating cutaneous and subcutaneous nodules in patients with known malignancy or as a primary manifestation of an unknown malignancy. All the FNAC done from January 2003 to August 2008 were reviewed (n = 55,556). Ninty-five patients (49 males and 46 females with age range of 4,96 years) with cutaneous/subcutaneous nodules which were diagnosed as metastasis were analyzed. Primary tumors of skin/subcutis were excluded from the study. In our study, 63 out of 95 cases had a known primary malignancy. Of these, five had underlying hematological malignancy and 58 patients had solid organ tumors. Lung carcinoma was seen to metastasize most commonly to skin in males and breast carcinoma in females. The most common site for a cutaneous/subcutaneous metastasis was chest wall [40 followed by abdominal wall (14) and scalp (9)]. Multiple site involvement was also observed (8). In 32 cases primary site was not known. They were most commonly diagnosed as poorly differentiated carcinoma followed by adenocarcinoma. FNAC can diagnose a variety of tumors in the skin and support the diagnosis of a metastasis in case of a known primary and offer a clue to underlying malignancy in case of an occult primary. Diagn.

Primary small cell carcinoma of the lung initially presenting as a breast mass: A fine-needle aspiration diagnosis

DIAGNOSTIC CYTOPATHOLOGY, Issue 3 2009
Wei Liu M.D.
Abstract The incidence of metastases to the breast from extramammary sites is relatively low compared with the incidence of primary breast carcinoma. Primary sites which have a predilection for metastases to the breast include, in the order of decreasing frequency, malignant melanoma, lymphoma, lung carcinoma, ovarian carcinoma, and soft tissue sarcoma, followed by gastrointestinal and genitourinary primaries. Most lung primaries metastasizing to breast represent adenocarcinoma. Other types of lung carcinoma, including small cell carcinoma, are relatively rare. We report a case of lung small cell carcinoma metastasizing to the breast and initially presenting with a breast mass in a 50-year-old female. The tumor was first diagnosed on a fine-needle aspiration biopsy specimen (FNAB) from the breast lesion and subsequently supported by core biopsy. A discussion of the differential diagnoses to consider on FNAB follows. Because of the difference in treatment for primary small cell carcinoma of breast versus primary small cell carcinoma of the lung, as well as the difference in prognosis for both malignancies, determining the site of primary malignancy is crucial to adequate patient care.

Incidence of Unsuspected Metastases in Lateral Cervical Cysts,

THE LARYNGOSCOPE, Issue 10 2000
Christine G. Gourin MD
Abstract Objective Solitary cystic squamous cell carcinoma metastases may be difficult to distinguish clinically from a benign cervical cyst. We sought to identify the incidence of solitary cystic squamous cell carcinoma metastasis in patients presenting with apparently benign cervical cysts. Study Design Retrospective review. Methods The records of all patients who presented with isolated lateral cervical cysts between 1983 and 1999 were reviewed. Patients with a clinically apparent primary malignancy, a history of head and neck cancer, a history of irradiation, or age less than 18 years were excluded from analysis, as were patients with a histological diagnosis of nonsquamous cell malignancy or those without a final histological diagnosis. Results One hundred twenty-one adult patients presented with an initial diagnosis of lateral cervical cyst. Metastatic squamous cell carcinoma was demonstrated histologically after surgical excision in 12 patients (9.9%). The incidence of malignancy was significantly greater in patients greater than 40 years of age (23.5%, P < .0001). Results of preoperative fine-needle aspiration (FNA) were negative for malignancy in five cases of metastatic squamous cell carcinoma. Panendoscopy with directed biopsies revealed an occult primary in the base of tongue in three patients, tonsil in one patient, and nasopharynx in one. No primary was found in six patients, despite repeated examinations and close follow-up. Conclusions Solitary cervical cysts in patients older than 40 years of age should be presumed to be carcinoma until proven otherwise. A negative FNA result may be misleading, because of hypocellularity of the cyst fluid. Excisional biopsy should be undertaken with provisions made for frozen-section analysis of the specimen and contingency panendoscopy with directed biopsies of Waldeyer's ring if frozen-section histological examination reveals malignancy.

Yu L, Guo W-C, Zhao S-H, Tang J, Chen J-L. Mitotic arrest defective protein 2 expression abnormality and its clinicopathologic significance in human osteosarcoma. APMIS 2010; 118: 222,29. Osteosarcoma is the most common primary malignancy of bone. Overexpression of mitotic arrest defective protein 2 (MAD2) is found in many human neoplasms, but its role in the oncogenesis of osteosarcoma is an untouched topic. The objective of this research was to observe the expression of MAD2 in human osteosarcoma and explore its clinicopathologic significance. MAD2 expression was analyzed in 48 primary osteosarcoma cases (19 osteoblastic osteosarcomas, 17 chondroblastic osteosarcomas and 12 fibroblastic osteosarcomas) using immunohistochemistry. A total of 20 normal bone specimens formed a control group. MAD2 was commonly overexpressed in human osteosarcoma. Immunopositivity was higher in tumors with lower differentiation and higher clinical stage. Increased expression of MAD2 was associated with earlier metastasis and poorer survival. Our findings provide evidence that MAD2 contributes to the pathogenesis and development of human osteosarcoma, Testing may have a clinical role in predicting prognosis, selecting appropriate chemotherapeutic strategies and providing novel strategies for osteosarcoma therapy.
