Afebrile tuberculous prostatic abscess with rectal fistula after intravesical Bacillus Calmette-Guérin immunotherapy.

Introduction: Intravesical Bacillus Calmette-Guérin immunotherapy is generally a safe treatment for non-muscle-invasive bladder cancer but sometimes causes complications.

Case Presentation: The patient was an 80-year-old man who had undergone Bacillus Calmette-Guérin immunotherapy for non-muscle-invasive bladder cancer. Two months later, he developed an irregular pelvic mass surrounding the prostate and rectum with no fever.

Predictive models of long-term survival outcomes following radical cystectomy.

Background: Identifying the likelihood of life-threatening recurrence after radical cystectomy by reliable and user-friendly predictive models remains an unmet need in the clinical management of invasive bladder cancer.

Methods: A total of 204 consecutive patients undergoing open radical cystectomy (ORC) for bladder cancer were retrospectively enrolled between May 2005 and August 2020. Clinicopathological and peri-ORC therapeutic data were extracted from clinical records.

Retroperitoneal urothelial carcinoma arising after bladder diverticulectomy: a case report.

Background: Urothelial carcinoma arises from the inner urothelial membrane of the renal pelvis, ureter, and bladder and often causes macrohematuria. Here, we report a rare case in which the patient developed non-symptomatic urothelial carcinoma anatomically outside the bladder wall 17 years after bladder diverticulectomy.

Case Presentation: An 82-year-old male patient previously underwent gastrectomy for stomach cancer and partial hepatectomy for intrahepatic cholangiocarcinoma.

Two cases of CRPC with mutation treated by olaparib after favorable response to cisplatin.

Introduction: Several prostate cancers carry homologous recombination repair mutations that respond to olaparib. Because of the mechanism, the efficacy of platinum-based therapy can be used to predict the efficacy of poly(adenosine diphosphate-ribose) polymerase inhibitors such as olaparib.

Case Presentation: We experienced two neuroendocrine prostate cancer patients who achieved a response duration of more than 1 year with platinum-based therapy.

Fibroblast growth factor receptor inhibitor erdafitinib promotes Mcl-1 degradation and synergistically induces apoptosis with Bcl-xL/Bcl-2 inhibitor in urothelial cancer cells.

Metastatic urothelial cancer is a lethal disease. Although recent advances in immunotherapies and targeted therapy against fibroblast growth factor receptor (FGFR)2/3 mutation (erdafitinib) have improved patient survival, there is still a critical need for novel therapeutic strategies for patients who do not benefit from these treatments. Evasion of apoptosis through amplifying anti-apoptotic Bcl-2 family proteins (Mcl-1, Bcl-xL, Bcl-2) is one mechanism responsible for treatment resistance in urothelial cancers, suggesting that targeting anti-apoptotic proteins may be a possible therapeutic strategy for urothelial cancers.

[USEFULNESS OF VIVID (VISUALIZATION OF VARIOUS INTEGRATION WITH DIFFUSION) ON COGNITIVE FUSION PROSTATE BIOPSY].

(Purpose) We created an image reconstructing multiparametric MRI system called VIVID (Visualization of Various Integration with Diffusion) and examined the efficacy of VIVID in detecting prostate cancer. (Methods and materials) The subjects were 80 patients who underwent one target biopsy with reference to MRI images in addition to 8-20 biopsies. (Results) The significant cancer detection rate was 61%, the significant cancer detection rate of PI-RADS 4 or 5 was 55%, and the significant cancer detection rate of VIVID score 4 or 5 was 55%.

[SQUAMOUS CELL CARCINOMA WITH CLOACAL EXSTROPHY: A CASE REPORT].

A 41-year-old man with a history of cloacal exstrophy presented to a local clinic with abdominal pain and bowel sounds. He was noted to have pain at the site of scarring due to cloacal exstrophy and a laceration at its center, which was stained with feces. He was referred to our department because of an enterocutaneous fistula.
