We ascertain the association of postoperative infection on survival in patients with locoregionally advanced oral cavity squamous cell carcinoma (OCSCC).
A retrospective study of patients with stage III/IVA OCSCC undergoing curative-intent surgery was performed. Postoperative infection was considered within 30 days after surgery. Kaplan-Meier survival curves were used to compare overall survival (OS) in patients with postoperative infection. Cox regression and propensity-score matching were used to adjust for confounders.
Fifty-four of 114 patients had a postoperative infection. The 5-year OS in patients with a postoperative infection (24.1%) was lower than those without (65.2%; P < .0001). Postoperative infection was a negative predictor of OS after adjusting for patient, antibiotic, pathologic, and operative factors; the adjusted hazard ratio for OS was 2.54 (95% confidence interval, 1.27-5.09).
Postoperative infection is a strong negative predictor of OS in patients with OCSCC undergoing ablative surgery.
本研究旨在确定术后感染与局部晚期口腔鳞状细胞癌（OCSCC）患者生存之间的关系。
本研究回顾性分析了接受根治性手术的 III/IVA 期 OCSCC 患者。术后感染定义为术后 30 天内发生的感染。Kaplan-Meier 生存曲线用于比较术后感染患者的总生存率（OS）。采用 Cox 回归和倾向评分匹配来调整混杂因素。
114 例患者中有 54 例发生术后感染。术后感染患者的 5 年 OS（24.1%）低于无术后感染患者（65.2%；P<0.0001）。在调整了患者、抗生素、病理和手术因素后，术后感染仍然是 OS 的负预测因素；调整后的 OS 风险比为 2.54（95%置信区间，1.27-5.09）。
对于接受根治性手术的 OCSCC 患者，术后感染是 OS 的强烈负预测因素。
