细胞衰老是对激活的癌基因和破坏DNA的化疗做出反应而发生的一种终末细胞周期停滞。目前尚不清楚确诊时癌细胞衰老是否可以预测治疗结果。采用衰老指数(SI)对30例UICC IV期结直肠癌(CRC)患者的治疗结果与其确诊时的SI进行了回顾性相关分析。接受5-氟尿嘧啶/亚叶酸钙治疗的结直肠癌患者在治疗前出现SI阳性肿瘤时,无进展生存期显著延长(中位数12.0vs6.0月;P=0.044)。癌细胞衰老可预测转移性结直肠癌的治疗结果。需要对更大的患者队列进行前瞻性分析。
Cellular senescence is a terminal cell-cycle arrest that occurs in response to activated oncogenes and DNA-damaging chemotherapy. Whether cancer cell senescence at diagnosis might be predictive for treatment outcome is unknown. A senescence index (SI) was developed and used to retrospectively correlate the treatment outcome of 30 UICC stage IV colorectal cancer (CRC) patients with their SI at diagnosis. 5-Fluorouracil/leucovorin-treated CRC patients achieved a significantly longer progression-free survival when presenting with SI-positive tumours before therapy (median 12.0 vs 6.0 months; P=0.044). Cancer cell senescence predicts treatment outcome in metastasised CRC. Prospective analyses of larger patient cohorts are needed.
