[MUCINOUS CYSTIC TUMOR OF LOW MALIGNANT POTENTIAL THOUGHT TO BE OF URACHAL ORIGIN: A CASE REPORT].

Mucinous cystic tumor of low malignant potential (MCTLMP) is a very rare disease.The patient was a 50-year-old man. Contrast-enhanced computed tomography and magnetic resonance imaging showed a multiocular cystic lesion on the top of the bladder.

[A CASE OF URACHAL CARCINOMA WITH HIGH FREQUENCY MICROSATELLITE INSTABILITY (MSI-HIGH) TREATED BY PEMBROLIZUMAB].

A 75-year-old woman was admitted to our hospital with suspected gastrointestinal perforation and underwent emergency surgery. Bladder perforation was revealed during the surgery, and she was referred to our department. We detected a tumor on the apex of the bladder and performed partial resection of the bladder.

[Post-Operative Immediate Single Instillation of Chemotherapy as Prevention of Recurrence after Transurethral Resection of Intermediate-High Risk Non-Muscle-Invasive Bladder Cancer].

We retrospectively evaluated the efficacy of immediate single instillation (SI) of pirarubicine hydrochloride (THP) in the chemoprevention of intermediate and high risk patients with non-muscle-invasive bladder cancer (NMIBC). The study population consisted of 256 intermediate and high risk patients with NMIBC who underwent Bacillus Calmette-Guerin (BCG) induction therapy or delayed intravesical chemotherapy between 1999 and 2014. We introduced SI of 30 mg THP in 30 ml normal saline for all cases in 2010, and thus earlier cases could be considered as historical controls.

[Post-Operative Single Immediate Intravesical Instillation Chemotherapy as Prophylaxis for Reccurence after Transurethral Resection of Low Risk Non-Muscle-Invasive Bladder Cancer].

We evaluated the efficacy of single-dose instillation of pirarubicine hydrochloride (THP) in the chemoprophylaxis of non-muscle-invasive bladder cancer(NMIBC). In a retrospective study, 135 evaluable patients were assigned to three groups after transurethral resection of bladder tumors (TURBT). In group 1, patients received no adjuvant therapy after TURBT.
