Observation of Serological Index and Efficacy of Abiraterone Hydrochloride Tablets Combined with Endocrine Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer

ABSTRACT

Purpose: This study reviewed and analysed the serological indexes, clinical efficacy and common clinical indexes of patients with metastatic castration-resistant prostate cancer (mCRPC) treated with combination of abiraterone hydrochloride tablets and endocrine therapy. Method: This study is a retrospective analysis. A total of 133 mCRPC patients who were admitted to our hospital from January 2019 to December 2021 were selected as the study subjects. The patients were categorised into the experimental group (n = 51) and control group (n = 82) according to their treatment method. The control group was treated with docetaxel combined with endocrine therapy, whilst the experimental group was treated with combination therapy with abiraterone hydrochloride tablets. Subsequently, the clinical data of the two groups, including serum insulin-like growth factor-1 (IGF-1), human glandular kallikrein 2 (hK2), prostate specific antigen (PSA), vascular endothelial growth factor (VEGF) and serum carcinoembryonic antigen (CEA), were analysed. Result: The overall response rate of the experimental group (84.3%) was higher than that of the control group (72.0%). The serum levels of CEA, total prostate specific antigen, free prostate specific antigen, testosterone and androgen receptor splice variant 7 in both groups were lower than those of before treatment, and the values obtained by the experimental group were lower than those of the control group (p < 0.05). After treatment, the levels of CD3+, CD4+ and CD4+/CD8+ in both groups were higher than those before treatment, and the levels of CD8+, IGF-1, hK2, PSA and VEGF in the two groups decreased after treatment (p < 0.05). Conclusions: The use of abiraterone hydrochloride tablet combined with endocrine therapy for patients with mCRPC is effective and can improve clinical symptoms and serum cytokine levels (AU)
