PURPOSE: We aim to evaluate the impact of preoperative thrombocytosis on oncological outcomes in patients with bladder cancer (BC) who undergo radical cystectomy (RC).
METHODS: Retrospective data collection of 1092 patients managed by RC for BC from 2 tertiary-care centers was performed. Elevated platelet count (PLT) was defined as > 450 × 109/L. Univariable and multivariable logistic regression analyses were used to investigate the impact of thrombocytosis on oncological outcomes. These outcomes were also compared using Kaplan-Meier survival analysis.
RESULTS: The median follow-up was 50 months (32-64 months). Thrombocytosis was detected in 18.6% of the patients. The 3-year cancer-specific survival (CSS) for patients with normal PLT count was 92% which was higher than those with elevated PLT count (55%, P < 0.001). Similar results were found for the 6-year CSS with 82% for the no thrombocytosis group and 27% for the thrombocytosis group. Thrombocytosis was still significantly associated with poor prognosis for overall survival and recurrence-free survival (P < 0.001). In the multivariate analysis, CSS was significantly lower in patients with thrombocytosis (HR = 1.71, 95% CI = 1.22-2.39, P = 0.002). Patients with elevated PLT counts were also significantly more likely to receive adjuvant chemotherapy, to have a T stage > pT2b (P = 0.024), to have a positive lymph node, to have variant histology and positive resection margins, and to have concomitant carcinoma in situ (CIS) on final pathology (all P < 0.001).
CONCLUSIONS: Preoperative thrombocytosis was valuable for predicting the oncological outcomes of patients undergoing RC for BC.
