Background. Salvage radiation therapy is the “gold standard” of treatment for patients with recurrent prostate cancer after radical prostatectomy. However, the results of the effectiveness of salvage radiation therapy in patients with regional recurrences are significantly lower than in patients with local one of prostate cancer, and, as a rule, the progression of the disease more often continues lymphogenic, affecting the next barrier of lymph outflow – retroperitoneal lymph nodes.Aim. To develop a new more effective radical method of salvage radiation therapy in patients with regional relapses of prostate cancer after radical prostatectomy.Materials and methods. The radiotherapy department of the N. N. Blokhin National Medical Research Center of Oncology of the Ministry of Health of Russia has developed a new method of hypofractionation salvage radiation therapy of patients with regional recurrences of prostate cancer after radical prostatectomy, which includes treatment not only to regional recurrences, the bed of prostate and regional lymph nodes of the pelvis, but also and prophylactic radiation treatment to retroperitoneal lymph nodes.Results. 25 patients were treated with prophylactic radiation treatment to retroperitoneal lymph nodes from 2018 to 2021. The median follow-up of patients was 19 (7–22) months. In all patients, radiotherapy was performed in combination with hormone therapy with analogues of luteinizing hormone releasing hormone with a median duration of administration of 8 (6–10) months. All patients were treated without interruption according to the previously planned dosimetric treatment plans. At the end of the course of radiation therapy, none of the patients had any pronounced negative effects of the III–IV degree (according to the RTOG /EORTC scale). The 1-year local and biochemical control of the disease were 100 and 88 %, respectively.Conclusions. Initial data assessing the safety of the newly developed salvage radiation therapy technique in hypofractionation mode with additional prophylactic of retroperitoneal lymph nodes demonstrate good tolerability. However, further study and randomized phase III clinical trial are required to determine clinical efficacy.

Introduction. The primary focus for improving medical care is introduction of inpatient-replacement forms of healthcare for patients, particularly, with prostate cancer (PCa). Day-care facilities at outpatient institutions and hospitals are considered the most cost-effective and convenient for patients. It is expected that the introduction of new survey methodologies and the optimization of their use in day-hospitals of outpatient clinics will reduce the use of other diagnostic procedures, including invasive ones, and will allow the specialist to determine the treatment tactics and method.Objective. To improve the quality of PCa diagnosis with the use of high-tech advanced outpatient medical care.Materials & methods. To assess the appropriateness and effectiveness of transrectal prostate biopsies (TRPBs) in the day hospital, we have compared the statistics obtained in outpatient clinics with inpatient hospital divisions of the corresponding urban district. A comparative analysis of the data obtained using a standard examination algorithm was carried out: prostate-specific antigen analysis, digital rectal examination and transrectal ultrasound examination with a group of men who used multiparametric magnetic resonance imaging (mpMRI) in the examination algorithm prior to TRPB.Results. The average annual number of TRPBs performed in inpatient urology divisions (three сapital hospitals from Western urban district) was 344, and the PCa detection was 142 (41%). In the outpatient urological unit of the Branch No. 2, Moscow Outpatient Clinics No. 195 for the period from 2010 to 2017, the average annual number of TRPBs was 440, and the PCa detection was 153 (35%) Thus, from the above data, it appears that with inpatient-like PCa detection, one large outpatient urological unit performed on average 24% more TRPBs (440 versus 344) than three inpatient urological divisions in a comparable period of time. When comparing histological data obtained after TRPBs in the absence and presence of pelvic mpMRT, a reliable difference (42% vs 35%) was found in PCa detection, respectively.Conclusion. mpMRI due to its high sensitivity and specificity in PCa diagnosis, which can be recommended as a mandatory diagnostic step before TRPB. In addition, mpMRI can significantly reduce the number of unnecessary TRPBs, increase the effectiveness of timely PCa diagnosis at the early stages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
