Abstract

BACKGROUND: The detrimental impact of lymphovascular invasion (LVI) in prostate cancer (PCa) on biochemical recurrence has been described; the impact of LVI on overall survival (OS) remains unclear. This investigation sought to evaluate the impact of LVI on OS in patients with PCa.

METHODS: We examined men with nonmetastatic PCa treated with radical prostatectomy between 2010 and 2015. Only men with documented LVI status were included (n = 232,704). Patients were stratified according to final pathologic T stage (pT2, pT3a, and pT3b).

RESULTS: Of the 232,704 patients who met inclusion criteria, 17,758 (8%) were found to have LVI on final pathology. Overall, 174,838 (75%), 40,281 (17%), and 17,585 (8%) patients had pT2, pT3a, and pT3b disease, respectively. Median follow-up was 42.7 months (27.1-58.7). At 5 years, the OS in LVI versus non-LVI patients was 94% versus 95% in pT2 (P = .0004), 92% versus 95% in pT3a (P < .0001), and 86% versus 92% in pT3b (P < .0001). On multivariable analysis, LVI status was not an independent predictor of OS in pT2 disease (hazard ratio, 1.12; 95% confidence interval [CI], 0.93-1.36; P = .2). In pT3a and pT3b disease, presence of LVI had 1.2-fold (95% CI, 1.03-1.44; P = .02) and 1.4-fold (95% CI, 1.20-1.59; P < .001) higher overall mortality than their counterparts without LVI.

CONCLUSIONS: Our report demonstrates the detrimental impact of LVI on OS in locally advanced PCa (pT3a and higher). This information may prove valuable when risk stratifying based on final pathology.
