Role of somatostatin receptor SSRT5-AS1 in predicting biomarkers of primary androgen deprivation therapy on prostate cancer in Indonesian population

Abstract

Introduction: Androgen deprivation therapy (ADT) has been the pivotal strategy for treating advanced prostate cancers. Despite the high efficacy of ADT in prohibiting tumor growth, >50% cases of prostate cancer will develop into an aggressive variant known as castration resistant prostate cancer (CRPC). This study aimed to evaluate the potential role SSRT5-AS1 expression as a biomarker for response to ADT in prostate cancer.

Materials and methods: In total, 36 patients diagnosed with prostate cancer at Dr. Sardjito General Hospital, Yogyakarta, Indonesia were enrolled from 2015 and 2019. The expression of SSRT5-AS1 in primary tumors was quantified using quantitative real-time polymerase chain reaction.

Results: The mean age of patients enrolled in this study was 69.07 ± 8.7 years, and the mean of prostate-specific antigen in patients was 141.22 ±112.28 ng/ml. Compared with the median, a higher expression of SSTR5-AS1 had more significant prognostic value than the variable shorter time to CRPC (p= 0.043).

Conclusion: This study demonstrated that high expression of SSRT5-AS1 is a promising biomarker to predict response to ADT in patients with prostate cancer.
