Diagnosis of this carcinoma requires that at least 25% of the tumor tissue should consist of an extracellular mucin pool. In this report, we present a case of prostate prostate mucinous adenocarcinoma with signet ring cells.展开更多
Approximately 70% of newly diagnosed bladder tumors are non-muscle invasive bladder cancer (NMIBC). NMIBC accounts for approximately 80% of total bladder cancer cases.

NMIBC accounts for approximately 80% of total bladder cancer cases. Bacillus Calmette-Guerin (BCG) instillation and maintenance is considered as the standard adjuvant treatment for superficial bladder cancer. A number of randomized studies have focused on the benefit of maintenance therapy following initial BCG induction. To provide further insights into the effect of intravesical instillation on recurrence in patients with NMIBC, we analyzed this relationship by conducting an updated detailed meta-analysis. Evidence suggested that adjuvant intravesical BCG with maintenance treatment is significantly effective for the prophylaxis of tumor recurrence in patients with NMIBC.展开更多
