Survival of patients with lymph node versus bone versus visceral metastases according to CHAARTED/LATITUDE criteria in the era of intensified combination therapies for metastatic hormone‐sensitive prostate cancer

Background The first approvals of novel systemic therapies within recent years for metastatic hormone‐sensitive (mHSPC) were mainly based on improved overall survival (OS) and time to castration resistance (ttCRPC) in mHSPC patients stratified according to CHAARTED low (LV) versus high volume (HV) and LATITUDE low (LR) versus high‐risk (HR) disease. Methods Relying on our institutional tertiary‐care database we identified all mHSPC stratified according to CHAARTED LV versus HV, LATITUDE LR versus HR and the location of the metastatic spread (lymph nodes (M1a) versus bone (M1b) versus visceral/others (M1c) metastases. OS and ttCRPC analyses, as well as Cox regression models were performed according to different metastatic categories. Results Of 451 mHSPC, 14% versus 27% versus 48% versus 12% were classified as M1a LV versus M1b LV versus M1b HV versus M1c HV with significant differences in median OS: 95 versus 64 versus 50 versus 46 months (p
