INFLUENCE OF THE METABOLIC SYNDROME ON THE QUALITY AND LIFETIME OF PROSTATE CANCER PATIENTS WITH THE DEVELOPMENT OF BONE MEATSTASES

Abstract

Summary. Aim: to determine the quality of life, progression-free (PFS) and overall survival (OS) of patients with localized prostate cancer (PC) with existing metabolic syndrome (MS) and the development of bone metastases (BM) after radical prostatectomy (RP). Objects and methods: а retrospective clinical study diagnosed in 35 patients with localized PC and development of BM. Patients with a moderate (Grade group 2.3) and high (Grade group 4.5) risk of disease progression are divided into subgroups based on the presence and absence of MS. Analyzed indicators of recurrence-free and overall survival; the quality of life of patients was assessed using the QLQ-C30 questionnaire. Results: among 35 study participants after RP with the development of BM – 27 (77.1%) have MS, 8 (22.9%) haven’t features of MS. MS was found in 25.9% of patients with GG 2.3 and 74.1% of GG 4.5; the absence of MS was observed in 62.5 and 37.5% of patients, respectively. The median progression-free survival of patients with РС GG 2.3 and existing MS was 13.3% lower compared to the rate of patients without MS; in patients with PС GG 4.5 – by 10.5%. They also noted a decrease in the median overall survival of patients with MS compared to the rate of patients without MS by 6.4 (GG 2.3) and by 23.9% (GG 4.5). The data of the study demonstrate a decrease in the general health status of patients before RP and at the time of development of BM with existing MS by 27.6%, without MS by 5.5%. Decrease in quality-of-life indicators was noted in the following indicators: social status, fatigue, lack of appetite and the presence of financial difficulties. Conclusion: the investigation analysis showed that presence of metabolic syndrome influence on decreasing quality of life, progression-free survival and overall survival rates in patients with prostate cancer.
