Risks of metabolic diseases and androgen deprivation therapy for prostate cancer in a Chinese population: a prospective multi-centre cohort study

Purpose Androgen deprivation therapy (ADT) use in prostate cancer (PCa) has seen a rising trend. We are looking into the relationship between ADT and development of metabolic diseases in Chinese patients. Methods This is a prospective multi-centre cohort yielded from the READT database (Real-life experience of ADT in Asia), in which patients diagnosed of PCa and offered ADT were prospectively recruited since 2016. Chinese patients recruited from Hong Kong were selected and compared to another cohort of newly diagnosed PCa patients in Hong Kong (HK-Cap database), which was collected prospectively and retrieved retrospectively for this study. Patient outcomes are followed through for 2 years. We compared between the groups the new diagnoses of hypertension, diabetes and hyper-lipidaemia, as well as the initiation of related medication for these conditions. Baseline characteristics including pre-treatment comorbidities, medications and tumour characteristics are documented. Results 151 patients receiving ADT (from READT database) and 447 patients not receiving ADT (from HK-Cap database) were analysed. ADT is related to higher risks of developing any of concerned medical co-morbidities (23.8% vs 13.0*, p = 0.001) and new-onset DM (16.6% vs 4.4%, p < 0.001). Initiation of new medications is also more common in ADT patients. New anti-hypertensives (37.8% vs 12.5%, p < 0.001), oral hypoglycemic agents (12.6% vs 4.9%, p = 0.001), insulin (4.0% vs 0.05%, p = 0.001) and statin (23.7% vs 12.8%, p = 0.023) are more commonly added in ADT cohort. Conclusion Chinese receiving ADT are exposed to increased risks of new-onset hypertension, diabetes and hyper-lipidaemia, and a higher likelihood of stepping up pharmaceutical control for pre-existing comorbidities. This highlights physicians' role to monitor metabolic profiles in at-risk men upon offering ADT.

Automated summary

This study investigates the relationship between androgen deprivation therapy (ADT) and the development of metabolic diseases in Chinese prostate cancer patients. The results demonstrate that Chinese patients receiving ADT have a higher risk of developing hypertension, diabetes, and hyper-lipidemia, as well as a higher likelihood of needing medication to control pre-existing comorbidities.
