Men with good health-related quality of life at baseline are more likely to have favorable outcomes following radical prostatectomy (RP) for high-risk prostate cancer, according to study findings presented at the ASCO Genitourinary Cancers Symposium 2022.
In a propensity-score matched analysis of 636 patients with high-risk prostate cancer, the biochemical recurrence-free survival rate at 5 years was significantly higher — 61% vs 28% — among those who had a preoperative global health status (GHS) of 70 or higher vs lower than 70 on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30), Thilo Westhofen, MD, of Ludwig-Maximilians-University Munich in Germany reported on behalf of his team. The metastasis-free survival rate at 5 years was also significantly higher among patients with a good GHS at baseline: 86% vs 68%, respectively. The groups were well matched by age, PSA, pT stage, Gleason grade, positive surgical margin rate, and lymph node involvement.
A multivariate analysis confirmed that a GHS of 70 or more independently predicted a 40% and 49% decreased risk for biochemical recurrence and metastasis, respectively, Dr Westhofen reported. Adding baseline health-related quality of life to their model improved prediction of biochemical-recurrence-free survival, the primary endpoint, by 8%.
Our findings highlight baseline health-related quality of life to be a valuable and robust prognostic factor for patients with localized high-risk prostate cancer prior to RP, Dr Westhofen said. Baseline good general health-related quality of life accurately predicts increased metastasis-free survival and biochemical recurrence-free survival.
