Background Primary urinary tract lymphoma (PUTL) is an uncommon disease with only a few case reports in the literature. Materials and Methods Information about 1264 patients diagnosed between 1983 and 2013 with PUTL was extracted from the Surveillance, Epidemiology and End Results database. Kaplan–Meier curves and multivariable regression analysis were used to analyze the survival and identify prognostic factors. A comparison of nodal diffuse large B-cell lymphoma (DLBCL) with PUTL DLBCL was performed. In addition, we compared the characteristics of kidney and bladder lymphoma. Results PUTL incidence was 1 case/1,000,000 people per year. DLBCL was found to be the predominant histology. 5-Year overall survival and cancer-specific survival were 49% and 58%, respectively. DLBCL histology, male gender, stage III–IV disease, and advanced age were found to be poor prognostic factors. Surgery may be beneficial. Urinary tract DLBCL has a worse prognosis than nodal DLBCL. Conclusion To our knowledge, this is the largest population-based study of PUTL in the literature. The survival of patients has not improved in the era of modern therapies therefore new treatments are needed.

Background: Urinary bladder cancer is an important cause of morbidity and mortality due to urological conditions. It is tenth most common cancer overall in both sexes. It is seventh most common cancer overall and second most common cancer of genitourinary tract in males. Ninety five percent of bladder tumors are epithelial and the rest are mesenchymal, of which majority are primary urothelial tumors. Urothelial tumors are classified into infiltrating urothelial carcinoma with its variants and non-invasive urothelial neoplasias. Tumor stage is the strongest prognostic parameter.Aims and Objectives: The current study was designed with an aim to elucidate the histologic pattern of bladder tumors and observe whether any association between histologic grade and muscle invasion exists.Materials and Methods: This descriptive study was carried out on 84 cases of urinary bladder tumors received in Department of Pathology, College of Medical Sciences and Teaching Hospital during a time period of 5 years from January 2012 to December 2016.Results: The mean ± SD of age of presentation was 63±13 years with a male female ratio 3.2:1. Ninety-five percent cases were primary epithelial tumors and 93% cases were of urothelial origin. Low grade papillary urothelial carcinoma was the most common urothelial tumor (40.5%) followed by high grade papillary urothelial carcinoma (34.5%). Some rare types like primary adenocarcinoma and small cell carcinoma were also seen in this study (1.2% each). Muscle invasion was significantly higher in high grade (66%) as compared to low grade papillary urothelial carcinoma (3%). Muscle tissue was absent in 8 (9.5%) cases.Conclusion: There is relationship of histologic grade with aggressiveness of tumor. Most of the high grade tumors are muscle invasive at presentation. Submission of muscle tissue is important for optimal patient management.Asian Journal of Medical Sciences Vol.9(6) 2018 45-50

PURPOSE:To determine if the combination of photodocumentation and electronic medical record keeping led to changes in the management of suspicious lesions in patients with bladder cancer undergoing surveillance cystoscopy. METHODS:We reviewed the charts of all patients undergoing surveillance cystoscopy for bladder cancer during a 15-month period. We evaluated patients who had photodocumentation of bladder lesions in our electronic medical record (EPIC). Baseline demographics, surveillance data, and biopsy results were collected, and the outcome of photodocumentation was analyzed. A cost base analysis was performed using figures obtained from the billing department. RESULTS:During the study period, 50 patients underwent flexible cystoscopy for bladder cancer surveillance at our institution. Fifteen were identified who met the study criteria. Using photodocumentation in EPIC, nine patients had well-documented lesions that had no change during the surveillance period with negative urine cytology and therefore did not undergo biopsy. Six patients, however, did undergo biopsy based on a change in the appearance of the lesion. Biopsies demonstrated 3 benign lesions, 2 low-grade transitional cell carcinomas, and 1 muscle-invasive lesion. An economic base analysis demonstrated a cost reduction of 27% and 55% compared with office-based biopsy and transurethral resection of bladder tumor, respectively, by using photodocumentation. CONCLUSIONS: Photodocumentation of lesions during flexible cystoscopy is a useful tool in bladder cancersurveillance. It provides support for clinical decisions and is a cost-effective way to monitor patients undergoing frequent interventions.
