Feasibility of prostatectomy without prostate biopsy in the era of new imaging technology and minimally invasive techniques.

Background: Routinely, after receiving prostate specific antigen (PSA) testing and digital rectum examination, patients with suspected prostate cancer are required to undergo prostate biopsy. However, the ability of ultrasound-guided prostate biopsy to detect prostate cancer is limited. Nowadays, a variety of diagnostic methods and more sensitive diagnostic methods, such as multi-parameter prostate magnetic resonance imaging (mpMRI) and prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) can be applied clinically.

Results: All patients were performed with operation, and pathologically diagnosed as sarcomatoid renal cell carcinoma.

[Diagnosis and treatment of malignant bladder non-epithelial tumors].

Objective: To study the clinical diagnosis, treatment, and prognosis of malignant bladder non-epithelial tumors.

Methods: The clinical data of 17 cases with malignant bladder non-epithelial tumor, 15 males and 3 females, aged 28 (3-73), were analyzed.

Results: Ten of the 17 cases were diagnosed as with rhabdomyosarcoma, 2 with malignant lymphoma, and 2 with malignant pheochromocytoma, 2 with leiomyosarcoma, and 1 with carcinosarcoma.

[Expression of Survivin in transitional cell carcinoma of urinary bladder and its clinical significance].

Objective: Survivin is a member of the inhibitors of apoptosis protein (IAP) family. Recent researches had shown that survivin plays an important role in oncogenesis. This study was designed to investigate the expression of survivin in transitional cell carcinoma (TCC) of urinary bladder and its clinical significance.
