Diagnosis and treatment of urothelial carcinoma of the prostate / 中华泌尿外科杂志

ABSTRACT

Objective:To discuss the diagnosis and treatment of urothelial carcinoma of the prostate.Methods:The clinical data of 25 patients with prostate urothelial carcinoma from January 2011 to November 2019 were retrospectively analyzed.Among the 25 patients, the age of onset was 39 to 85 years old, with an average of (63.4±11.2) years old, 13 patient presented with gross hematuria, 9 patients presented with dysuria, and 3 presented with bladder irritation. The PSA of 25 patients was within the normal range (less than 4 ng/ml). 17 cases of pelvic MRI showed abnormal signals in the bladder and prostate area, 3 cases indicated that prostate cancer had invaded the bladder, and 14 cases considered bladder cancer Invasion of the prostate suggests a cauliflower-like abnormal signal in the bladder area. 6 of this 14 patients have a history of bladder cancer. All 25 patients underwent surgical treatment, and 14 underwent transurethral diagnostic resection, of which 6 cases accepted radical cystectomy later. One patient underwent radical cystectomy combined with pelvic lymph node dissection 15 days after the first operation.9 cases received radical cystectomy.2 cases undergoing transurethral palliative resection due to multiple metastases before the operation.Results:The postoperative pathological diagnosis of 25 cases were all prostate urothelial carcinoma, 13 cases were accompanied by bladder urothelial carcinoma, secondary prostate urothelial carcinoma, and 12 cases were primary prostate urothelial carcinoma. After the operation, 13 patients were further treated. Among the patients with secondary prostate urothelial carcinoma, 7 patients received bladder perfusion, 2 patients received GC chemotherapy, 1 patient received local pelvic radiotherapy.25 patients were followed up for 2 to 36 months with an average of (21.5±10.1) months. Among them, lymph node metastasis were seen in 17/25 patients. lymph node metastasis were found in 7/25 before surgery, and 1/25 found lymph node metastasis during surgery. Among the patients with distant metastases afterwards, multiple metastases throughout the body (4/14), lung metastases only (6/14), and bone metastases only (4/14), the 1-year survival rate was 88% (22/25), the 2-year survival rate was 40% (10/25), and the 3-year survival rate was 28% (7/25).Conclusions:The diagnosis depends on histopathological examination. Early diagnosis may help improve prognosis. The first choice is a comprehensive treatment based on radical surgery.
