The role of cystoprostatectomy in management of locally advanced prostate cancer: A systematic review

Abstract

Background: The role of cystoprostatectomy for the treatment of locally advanced prostate cancer (LAPC) was evaluated by a comprehensive review of contemporary literatures. Methods: A systematic search of English language literatures using PubMed, EMBASE, Web of Science, and Cochrane library, from 1990 to 2018, was performed. Two independent authors reviewed abstracts as well as full-text articles and extracted data from the selected manuscripts. Results: After the literature research, seven articles with a total of 211 patients were identified. Both 120 cases who received cystoprostatectomy for the primary treatment of LAPC and 91 cases for the salvage surgery after local recurrence were finally included. Overall incidence of positive surgical margins ranged from 25 to 78%. The incidence of major complications caused by the surgery during the follow-up time was limited. It had been reported that among LAPC patients who received cystoprostatectomy combined with adjuvant therapies, 5-year cancer-specific survival rate and 5-year biochemical progression-free survival was up to 87.1% and 62.2%. Moreover, symptoms such as hematuria and other urination dysfunctions, as well as patients' quality of life were significantly improved after cystoprostatectomy in LAPC patients with the bladder invasion. Conclusions: Cystoprostatectomy can serve as an alternative to the surgical step of multimodal therapy for highly selected LAPC patients with the bladder invasion, which may improve patients' symptoms and related quality of life. Therefore, cystoprostatectomy as an option for the treatment of LAPC with the bladder invasion may be feasible and safe with considerable survival outcomes.
