Abstract

Purpose: Metastatic prostate cancer (Pca) is a complex disease with diverse clinical characteristics and outcomes across the geographical distribution. Herein, we present a series of patients from the Middle East, aiming at identifying disease outcomes and prognostic factors specific to this regional context.<br />Methods and Materials: This is a retrospective study of patients with metastatic Pca, diagnosed at King Hussein Cancer Center, Jordan, between 2006 and 2018. Survival was estimated using the Kaplan-Meier method and compared using the log-rank test. Factors that significantly affected overall survival (OS) in the univariable analysis were examined in a multivariable Cox regression analysis.<br />Results: A total of 188 patients with metastatic Pca were included in this analysis, of whom 168 (89%) had de novo metastatic disease. The median age at diagnosis was 68 years, 144 (77%) had bone metastasis, 32 (17%) had visceral metastasis, and 126 (67%) had high-volume disease. At a median follow-up of 67 months, the median OS was 44.3 months. The following factors predicted inferior OS in univariable analysis: smoking, normal BMI, high-volume disease, high alkaline phosphatase (ALP), previous local therapy for prostate, and orchiectomy versus medical androgen deprivation therapy (ADT). On multivariable analysis, high-volume disease (hazard ratio [HR], 1.92 [95% CI, 1.17 to 3.13]; P = .0094), high ALP (HR, 2.136 [95% CI, 1.38 to 3.31]; P < .001), and orchiectomy (HR, 2.40 [95% CI, 1.51 to 3.82]; P < .001) emerged as independent factors for inferior OS.<br />Conclusion: Metastatic Pca outcomes in our population closely align with the global benchmark. High volume status, elevated ALP, and performance of surgical as opposed to medical ADT emerge as prognostic indicators of poor survival.
