Introduction: In de novo metastatic hormone-sensitive prostate cancer (mHSPC) treated with upfront intensification using androgen receptor signaling inhibitor or chemotherapy (Docetaxel), achieving a PSA nadir less than 0.2 ng/mL, indicative of superior survival in trials, may often be unattainable in real-world settings. We explored the predictive value of the degree of PSA decline and time to PSA nadir (TTPN) on oncological outcomes.

Purpose Of Review: Renal cell carcinoma (RCC) is resistant to chemotherapy. Adjuvant interferon and tyrosine kinase inhibitors were ineffective. Immune checkpoint inhibitors (ICIs), however, have shed new hope in this setting.

Background: Prednisolone/prednisone coadministration with abiraterone may explain abiraterone-related increase in cardiovascular risk. We explored this postulation and glucocorticoid's association with cardiovascular risk.

Methods: Patients with prostate cancer on androgen deprivation therapy and enzalutamide, or abiraterone with 5 mg (ABI + P5) or 10 mg (ABI + P10) daily total prednisolone/prednisone were followed up for major adverse cardiovascular events (MACE).

Background: Impaired health-related quality of life is commonly observed in patients with obesity who are scheduled for bariatric surgery. However, bariatric surgery tends to improve quality of life physically, with no final conclusion regarding mental domains.

Objective: To assess changes of patient-reported outcomes in terms of health-related quality of life, depression, anxiety status, and physical activity (PA) after bariatric surgery among patients with obesity.

Aims: To compare disease remission rates, weight loss, and changes of metabolic parameters of patients after bariatric surgery with nonsurgical patients.

Methods: Based on the 2006-2017 Hospital Authority database, a population-based retrospective cohort of obese type 2 diabetes mellitus (T2DM) patients with and without bariatric surgery were identified. Surgical patients were matched with nonsurgical patients on 1-to-5 propensity score.
