RESUMO

<p><b>OBJECTIVE</b>To assess the value of fluorescence in situ hybridization (FISH) in the diagnosis of bladder cancer.</p><p><b>METHODS</b>Urine samples from 100 patients suspected of having bladder cancer were collected before cystoscopy for immediate urine cytology and FISH analysis. The criteria for FISH abnormality were determined by evaluating the urine specimens from 20 subjects without urogenital neoplasm.</p><p><b>RESULTS</b>The overall sensitivity of cytology and FISH was 43.2% and 82.4%, and their specificity was 92.3% and 88.5%, with diagnostic concordance rate of 56.0% and 84.0%, respectively. The differences between FISH and cytology showed statistical significance in the sensitivity, diagnostic concordance rate, non-muscle-invasive cancer and primary cancer.</p><p><b>CONCLUSION</b>The sensitivity and efficiency of FISH in the detection of bladder cancer are superior to those of cytology, especially for prophase cancer.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the clinicopathological characteristics of synchronous squamous cell carcinoma (SCC) of the renal pelvis and SCC of the ureter.</p><p><b>METHODS</b>The clinical data of two cases of synchronous SCC of the renal pelvis and SCC of the ureter were retrospectively reviewed and analyzed. In case 1, a 68-year-old man with hematuria for a month, imaging modalities revealed a right renal pelvis tumor and a right distal ureter tumor. The patient underwent nephroureterectomy and excision of the bladder cuff. Case 2, a 60-year-old man with the complaint of lower abdominal pain and left flank pain for a month, was diagnosed as left distal ureteral stone in another hospital. Ureterolithotomy was performed and a ureteral tumor was found at the lower site of the stone intraoperatively. The pathological report demonstrated SCC, and the patient was transferred to our hospital for further treatment. We found a left renal mass invading the left hemicolon during surgery, and nephroureterectomy was performed with a bladder cuff excision, left hemicolon resection, and also complete lymph node dissection. Neither of patients received adjuvant radiotherapy/chemotherapy.</p><p><b>RESULTS</b>Moderately differentiated SCC was reported in both of renal pelvis and ureter in case 1 and the tumor invaded the subepithelial connective tissue in the renal pelvis and superficial muscle in the ureter. In case 2, moderately differentiated SCC of the left renal pelvis with colon metastasis and poorly differentiated SCC of the ureter was reported with two retroperitoneal lymph node metastases. The two patients died from tumor recurrence and metastasis 5 and 6 months after the surgery, respectively.</p><p><b>CONCLUSION</b>Synchronous SCC of the renal pelvis and SCC of the ureter are rare and has high likeliness of early recurrence and metastasis, often with poor prognosis.</p>
