The DaBlaCa-13 Study: Short-term, Intensive Chemoresection Versus Standard Adjuvant Intravesical Instillations in Non-muscle-invasive Bladder Cancer-A Randomised Controlled Trial.

Background: Instillation therapy for non-muscle-invasive bladder cancer (NMIBC) reduces recurrences but is associated with side effects. Preoperative instillation of chemotherapy could potentially be associated with fewer side effects compared with adjuvant instillations and in some patients make tumour resection (transurethral resection of the bladder tumour [TURBT]) superfluous.

Objective: To investigate tumour response and adverse events related to short-term, intensive chemoresection with mitomycin C compared with adjuvant instillations in patients with recurrent NMIBC.

[Primary adenocarcinoma of the ureter].

Primary adenocarcinomas of the renal pelvis and ureter are very rare tumours, representing less than 1% of the malignant tumours of the ureter and the renal pelvis. A case of adenocarcinoma of the ureter in a 62-year-old woman with no prior history of urological disease is presented. The patient died postoperatively after nefrectomy due to rapid disease recurrence.
