Abstract:
Objective To investigate the efficacy of pretreatment systemic inflammation response index (SIRI) in predicting the prognostic of prostate cancer (PCa) patients treated with maximal androgen blockade (MAB).Methods The data of 351 PCa patients who had undergone MAB as first-line therapy between January 2010 and June 2015,were retrospectively analyzed.The age of patients in our cohort ranged from 51 to 89 years old,mean 76 years old.The median value of PSA was 91.60ng/ml,ranging 0.11-1 000.00 ng/ml.39 cases had a Gleason score of 6,47 cases had a score of 3 + 4,89 cases had a score of 4 +3,107 cases had a score of 8,and 69 cases had a score of 9-10.158 cases had bone metastasis.Patients were categorized in two groups using a cut-off point of 1.2 as calculated by the receiver-operating curve analysis.Correlations between SIRI and clinical characteristics were analyzed.Meanwhile,univariate and multivariate cox regression analyses were performed to determine the associations of SIRI with progression-free survival (PFS),cancer-specific survival (CSS) and overall survival (OS).Results The median follow-up duration was 43.0 months,ranging 9-75 months.The disease progression occurred in 162 patients,91 patients died,including 75 who died because of PCa at the end of the last follow-up.The differences of age,Gleason score and incidence of metastasis between low SIRI group (＜ 1.2) and high SIRI group (≥1.2) were not significant (P ＞0.05).But the patients in high SIRI group had higher PSA (P =0.046).Multivariate analyses identified SIRI,Gleason score and metastasis as independent prognostic factors for PFS,CSS and OS.Conclusions Pretreatment SIRI ≥ 1.2 was an independent predictor for poor prognosis in PCa patients treated with MAB.
