研究概要

我们完善了 ASCC 的预后因素。

中文摘要

肛门鳞状细胞癌(ASCC)与人乳头瘤病毒高度相关。标准治疗为剂量一致、缺乏分层的放化疗。p16INK4A(p16)免疫组化染色是人乳头瘤病毒的替代指标,可预测结局。本研究结合包括TIL(肿瘤浸润淋巴细胞)评分在内的临床病理因素进行评估。

采用独立、多中心队列,纳入 257 例接受放化疗的 ASCC 患者;对治疗前活检样本进行 p16 和 TIL 染色及评分。按分期、p16 和 TIL 评分绘制无病生存期(DFS)、总生存期及癌症特异性生存期的 Kaplan-Meier 曲线,并以 log-rank 检验评估预后作用。采用 Cox 回归进行多变量分析。

分期、性别、p16 和 TIL 均为独立预后因素。p16 阴性相较阳性、T3/4 相较 T1/2、男性相较女性,以及 TIL1 相较 TIL3 的死亡(总生存期)风险比分别为 2.51(95% CI 1.36–4.63)、2.17(1.34–3.5)、2.42(1.52–3.8)和 3.30(1.52–7.14;均 P<0.05)。

本研究进一步明确了 ASCC 的预后因素。就早期疾病 DFS 以及局部晚期癌症总生存期/DFS 而言,p16 可在分期基础上增加风险分层信息。数据支持宿主免疫反应参与决定临床结局。这些因素将在 PLATO 研究(ISRCTN88455282)中前瞻性评估。

Using an independent, multicentre cohort of 257 ASCC treated with chemoradiotherapy, pretreatment biopsies were stained and scored for p16 and TIL. Kaplan-Meier curves were derived for outcomes (disease-free survival [DFS], overall survival and cancer-specific survival), by stage, p16 and TIL scores and Log-rank tests were carried out to investigate prognostic effect. A multivariate analysis was carried out using Cox regression.

Stage, sex, p16 and TILs were independently prognostic. Hazard ratios for death (overall survival) were 2.51 (95% confidence interval 1.36-4.63) for p16 negative versus p16 positive, 2.17 (1.34-3.5) for T3/4 versus T1/2, 2.42 (1.52-3.8) for males versus females and 3.30 (1.52-7.14) for TIL1 versus TIL3 (all P < 0.05).

We have refined prognostic factors in ASCC. p16 adds to stratification by stage with respect to DFS in early disease and overall survival/DFS in locally advanced cancers. Our data support the role of the host immune response in mediating outcomes. These factors will be prospectively evaluated in PLATO (ISRCTN88455282).
