A comparison of white-light cystoscopy and narrow-band imaging cystoscopy to detect bladder tumour recurrences

BJU INTERNATIONAL, Issue 9 2008
Harry W. Herr
OBJECTIVE To determine whether narrow-band imaging (NBI) cystoscopy enhances the detection of non-muscle-invasive bladder tumours over standard white-light imaging (WLI) cystoscopy, as surveillance WLI is the standard method used to diagnose patients with recurrent bladder tumours, but they can be missed by WLI cystoscopy, possibly accounting for early recurrences. PATIENTS AND METHODS We evaluated 427 patients for recurrent bladder tumours by WLI cystoscopy, followed by NBI cystoscopy as a further procedure, using the same video-cystoscope. Recurrent tumours visualized by WLI or NBI cystoscopy were mapped, imaged, biopsied and subsequently treated by transurethral resection (TUR) or fulguration. Biopsies or TUR specimens obtained by WLI and NBI were examined separately for presence of tumour. RESULTS In all, 103 patients (24%) had tumour recurrences; 90 (87%) were detected by both WLI and NBI and another 13 (100%) only by NBI cystoscopy. NBI detected extra papillary tumours or more extensive carcinoma in situ in 58 (56%) patients found to have recurrences. The mean number of recurrent tumours visualized on WLI cystoscopy was 2.3, vs to 3.4 seen on NBI cystoscopy (P = 0.01). CONCLUSION NBI cystoscopy improved the detection of recurrent non-muscle-invasive bladder tumours over standard WLI cystoscopy. [source]


4361: Management of orbital tumours with adjuvant iodine brachytherapy using "inverted" plaques

ACTA OPHTHALMOLOGICA, Issue 2010
T KIVELÄArticle first published online: 23 SEP 2010
Purpose To describe our experience in using "inverted" iodine plaques as adjuvant treatment after resection of orbital tumours. Methods Between 1999 and 2007, three patients (ages 17-48 years) underwent resection of an lacrimal gland tumour followed by application of an "inverted" iodine plaque manage any microscopic infiltration, i.e. a gold plaque carrying iodine-125 seeds on its convex rather than concave surface. In a fourth instance, the seeds were placed on the convex surface of a ruthenium rather than a gold plaque to manage an eye with a late extraocular recurrence of an irradiated uveal melanoma following resection of the extension. Results The diameter of the plaque was 20 mm. It was sutured to the sclera so that when the eye was in primary position the lacrimal fossa was targeted. When the eye moved, the irradiated volume naturally enlarged. A 40-56 Gy dose was calculated to the depth of 10 mm, and the dose at 5 mm was then calculated as 80-134 Gy. Treatment time was 59-154 hours. In one case, the iodine seeds were placed asymmetrically to limit radiation damage to the eyelid skin. In two patients, transient erythema of the upper eyelid developed, which resolved in a few months time. In case of the extraocular melanoma, dose was the same. Recurrent tumours have not developed. Conclusion An "inverted" iodine plaque is one option for adjuvant irradiation of the orbit which shields the eye from radiation damage. [source]


Percutaneous radiofrequency ablation of renal tumours: Case series of 11 tumours and review of published work

JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 5 2007
TW Watkins
Summary Detection of renal cell carcinoma (RCC) is increasing with the greater use of cross-sectional imaging and up to two-thirds of RCCs are discovered incidentally in asymptomatic patients. The traditional option of nephrectomy or partial nephrectomy may not always be appropriate. A minimally invasive treatment alternative is radiofrequency ablation (RFA). We retrospectively reviewed the RFA cases for renal tumours at our institution between January 2004 and June 2006. Thirteen RFA treatment sessions were conducted for 11 neoplasms in 11 patients. Mean patient age was 74.4 years (61,88 years). Imaging was carried out after ablation with a mean follow up of 8.0 months (2,26 months). No residual tumour was observed after the first RFA treatment in 82% of patients (nine of 11). Two patients required a second RFA treatment for residual (one) or recurrent tumour (one). RFA is emerging as a useful technique for treatment of small renal tumour. A number of short-term studies reflect this, however, long-term findings are still lacking. [source]


Long-term results of gastrectomy for ,-fetoprotein-producing gastric cancer,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 7 2010
M. Inoue
Background: ,-Fetoprotein (AFP)-producing gastric cancer is a rare tumour. It is said to have a high incidence of liver metastasis and poor prognosis. This study sought to evaluate long-term outcomes in such patients. Methods: Records of consecutive patients with gastric carcinoma who underwent preoperative measurement of serum AFP levels and gastrectomy were reviewed to identify those who satisfied the following criteria: preoperative AFP level exceeding 40 ng/ml with a decrease after gastrectomy, or raised preoperative AFP level (10,39 ng/ml) and resected tumour showing histologically characteristic features or immunohistochemically positive AFP production. Results: Of 3374 patients with gastric cancer, 53 (1·6 per cent) met the selection criteria. Tumours were characterized by a high incidence of nodal (79 per cent) or liver (53 per cent) metastasis. Preoperative serum AFP levels showed no correlation with tumour size, depth of invasion, disease stage or survival. The 5-year survival rate was 34 per cent. Five patients survived after recurrence following multimodal treatment. A rising AFP level during follow-up always led to tumour recurrence, but the level remained normal in 11 of 31 patients with recurrence. Conclusion: AFP-producing tumours represent a small subgroup of gastric cancer with high metastatic potential. Postoperative serum AFP level can help predict recurrence but a normal level does not mean absence of recurrence. Prognosis is not as poor as previously thought, and multimodal treatment may be worthwhile even in patients with recurrent tumour. Copyright © 2010 British Journal of Surgery Society Ltd.

Craniopharyngioma: a review of long-term visual outcome

CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 3 2003
Celia Chen MB BS MPHS
Abstract Purpose: To assess the clinical presentation and long-term visual outcome in a series of patients with craniopharyn-gioma. Methods: Retrospective case review. Results: Thirty-six patients were reviewed, comprising 19 female patients and 17 male patients. The age range was 2,77 years with a bimodal distribution of 17 children (mean age 10 years) and 19 adults (mean age 47 years). Blurred vision was the most common visual complaint (23 cases, 64%) and headache the most frequent systemic complaint (19 cases, 53%). The average duration of systemic symptoms was 45 weeks compared to 10 weeks for visual symptoms. Deficits in visual acuity occurred in 13 patients (36%) and showed no significant change from initial presentation to final review. Sixteen patients (44%) had bitemporal hemianopia on presentation and pleomorphism (change from one type of visual field defect to another) occurred in 11 patients. Recurrence of tumour occurred in 15 patients (42%) and was more likely in children (59%) than adults (26%). The mean time period to recurrence was 7 years. The average follow-up period for all cases was 10 years. Conclusion: Patients with craniopharyngioma generally present late, and the visual symptoms are often preceded by a long history of systemic symptoms. Children are more likely to present with systemic symptoms than adults. Visual field pleomorphism is a feature of craniopharyngioma and occurred in one-third of the patients. Local recurrence is common. Although magnetic resonance imaging is the recommended means of follow up, regular neuro-ophthalmic review is useful in the early detection of anterior visual pathway compression by recurrent tumour.

Prognosis following non-surgical second treatment in patients with recurrent hepatocellular carcinoma after percutaneous ablation therapy

LIVER INTERNATIONAL, Issue 3 2009
Manabu Morimoto
Abstract Objective: The aims of this study were to identify prognostic factors in patients who received a non-surgical second treatment for the development of recurrent hepatocellular carcinoma (HCC) after an initial percutaneous ablation therapy. Methods: We retrospectively studied 147 patients with HCC who had received an initially successful percutaneous ablation therapy. The patients were followed up using computed tomography and/or ultrasound every 3 months and a second treatment was performed for subsequent recurrent tumours. Results: The 3- and 5-year survival rates of the 147 patients were 90 and 65% respectively. During a mean follow-up period of 33 months, local or distant tumour recurrences developed in 77 of the 147 patients, and the 3- and 5-year survival rates after a second treatment in these 77 patients were 73 and 44% respectively. Forty-six of the 77 patients with up to three recurrent tumours received percutaneous ablation therapy for the second treatment, and the remaining 31 patients with more than three (multiple) recurrent tumours received transcatheter arterial chemoembolization for their second treatment. A multivariate analysis revealed the serum ,-fetoprotein level at the time of the appearance of the recurrent HCC (<100 ng/ml vs ,100 ng/ml, P=0.009) and the number of recurrent tumours (up to three vs more than three, P=0.009) to be independent prognostic factors after the second treatment. Conclusions: The serum ,-fetoprotein level and recurrent tumour number were prognostic factors following the second treatment in patients with recurrent HCC who had received an initially successful ablation therapy.

A comprehensive genetic profile of phyllodes tumours of the breast detects important mutations, intra-tumoral genetic heterogeneity and new genetic changes on recurrence,

THE JOURNAL OF PATHOLOGY, Issue 5 2008

Abstract The aims of this study were to identify genetic changes associated with malignant progression of the fibroepithelial neoplasms, phyllodes tumours of the breast (PTs), and to ascertain whether genetic progression occurs when PTs recur locally. A further aim was to assess whether the genetic data support the classification of these tumours into three subtypes, benign, borderline and malignant. 126 PTs (37 benign, 41 borderline, 48 malignant) were analysed by either array-CGH or the Illumina Goldengate assay. The large-scale genetic changes associated with malignant/borderline phenotypes were + 1q, + 5p, + 7, + 8, , 6, , 9p, , 10p and , 13. Cluster analysis of the array-CGH data supported the division of malignant and borderline PTs into two separate groups, one comprising almost all malignant lesions and the other, benign and borderline tumours. Interstitial deletions of 9p21 that involved the p16INK4a locus were present in many malignant/borderline PTs, and some of these appeared to cause homozygous loss. Loss of expression of p16INK4a was found frequently and this was associated with 9p deletion; we also identified one p16INK4a mutation and evidence of methylation of p16INK4a in malignant PTs. Our evidence shows that inactivation of this gene is important in the development of malignant PTs. In selected PTs, multiple areas of stroma were isolated and analysed separately by array-CGH. We found considerable intra-tumoral genetic heterogeneity. Analysis of paired primary and recurrent tumours showed that recurrent tumours often acquired new genetic changes; in particular, benign tumours tended to acquire changes characteristic of the malignant/borderline phenotype. We believe it likely that unfavourable sub-clones not easily identified by histology account for the unpredictable clinical behaviour of these tumours.

OBJECTIVE To assess the influence of 5-aminolaevulinic acid-induced fluorescence cystoscopy (FC) during transurethral resection (TUR) on the recurrence rate and the length of tumour-free interval in stage Ta/T1 transitional cell carcinoma (TCC) of the urinary bladder. PATIENTS AND METHODS In all, 122 patients with primary or recurrent stage Ta/T1 bladder TCC treated with TUR were enrolled in a prospective randomized study. In group A the TUR was performed with standard white-light endoscopy, and in group B with FC. The patients were followed using standard cystoscopy and urinary cytology. The recurrence-free interval was evaluated in whole groups, for single and multiple, and for primary and recurrent tumours separately. RESULTS At the time of the first cystoscopy (10,15 weeks after TUR) tumour recurrence was detected in 23 of 62 patients (37%) in group A, but only in five of 60 patients (8%) in group B. The recurrence-free survival rates in group A were 39% and 28% after 12 and 24 months, compared to 66% and 40% respectively in group B (P = 0.008, log-rank test). In separate analyses, the recurrence-free survival rates were significantly higher using FC in multiple (P = 0.001) and in recurrent (P = 0.02) tumours. In solitary and primary tumours the median time to recurrence was also longer in group B, but the difference was not statistically significant. CONCLUSION 5-aminolaevulinic acid-induced FC during TUR reduces the recurrence rate in stage Ta/T1 bladder TCC. The most significant benefit is in patients with multiple and recurrent tumours.

The hTERT-protein and Ki-67 labelling index in recurrent and non-recurrent meningiomas

CELL PROLIFERATION, Issue 1 2005
L. Maes
However, a number of these tumours recur even after total resection. The aim of this study is to evaluate the prognostic significance for recurrence of the human telomerase catalytic subunit (hTERT) in the cells of meningiomas. The expression of hTERT-protein can be evaluated by immunohistochemical staining using a monoclonal antibody against hTERT (clone 44F42, NCL-L-hTERT). The interdependence between tumour recurrence and cell proliferation in this study is analysed by Ki-67 immunoreactivity (clone MIB-1). Archival material from 29 non-recurrent and 32 recurrent tumours has been evaluated, including specimens from World Health Organization (WHO) stages I (n = 73), II (n = 2) and III (n = 12). Although the tumours were categorized as benign meningiomas following the WHO classification, recurrence in 22 of 50 cases did not correlate with the tumour stage. For hTERT staining, the following results were found for nucleolar and total nuclear staining, respectively: non-recurrent meningiomas, 2.9% (± 7.7) and 3.0% (± 8.0); recurrent meningiomas at first resection, 16.8% (± 19.7) and 31.6% (± 30.2). Concerning the Ki-67 labelling index (LI): for the group of non-recurrent meningiomas, results were 2.1% (± 1.7) and for the recurrent group at first resection, 1.7% (± 2.0). A significant difference was seen for the hTERT staining (P < 0.001) between the non-recurrent and recurrent meningiomas, whereas no statistical significance was found for Ki-67. In conclusion hTERT-positive meningiomas had a high incidence for recurrence. Ki-67 was a good marker of cell proliferation status of the tumours, but did not correlate with recurrence; thus, hTERT alone seemed to be a potential predictor for recurrence. [source]


Mohs' micrographic surgery for basal cell carcinomas on the eyelids and medial canthal areaI

ACTA OPHTHALMOLOGICA, Issue 4 2000
I. Characteristics of the tumours, details of the procedure
ABSTRACT. Purpose: To analyse the characteristics of eyelid basal cell carcinomas excised using Mohs' micrographic technique. Methods: Sixty-six eyelid basal cell carcinomas were excised using Mohs' micrographic technique. The tumours were classified into four subtypes; morpheiform, intermediate, nodular/micronodular and superficial. Data on previous treatment of the tumours were retrieved. Results: Thirty-two tumours (48%) were primary, 8 tumours (12%) were incompletely excised using conventional excision surgery and 26 tumours (39%) were recurrent. Nineteen of the 26 (73%) recurrent tumours and 14 of the 32 (44%) primary tumours were nodular/micronodular. To achieve radical excision, superficial tumours needed an average of 2.0, nodular/micronodular 2.5, intermediate 2.0 and morpheiform tumours 2.9 excisions. Conclusions: Eyelid basal cell carcinomas with ill-defined borders or recurrent tumours are well suited for Mohs' micrographic surgery. The extensions of the tumours are difficult to determine even in some less aggressive subtypes such as superficial and nodular/micronodular basal cell carcinomas. [source]
