BACKGROUND/AIM: This study evaluated the clinical significance of the mismatch repair (MMR) status and prognostic factors in patients with high-risk stage II colon cancer (CC).
This was a retrospective analysis of 237 patients diagnosed with high-risk stage II CC who had test results for MMR status.
Among the 237 patients, 76 (32.1%) were identified as having a microsatellite instability-high (MSI-H) status. No significant differences were identified in disease-free or overall survival according to the MMR status. Moreover, no association was found between the use of adjuvant chemotherapy and survival outcomes of the MSI-H group. In a multivariate survival analysis, the primary tumor location (right-sided versus left-sided, hazard ratio(HR)=0.172, p=0.003) and T-stage (HR=4.764, p=0.005) were identified as independent prognostic factors for disease-free survival.
The present study found that the MMR status was neither prognostic nor predictive in patients with high-risk stage II CC.
背景/目的：本研究评估了错配修复（MMR）状态及预后因素在高危II期结肠癌（CC）患者中的临床意义。
这是一项对237例诊断为高危II期CC且有MMR状态检测结果的患者进行的回顾性分析。
在237例患者中，76例（32.1%）被确定为微卫星高度不稳定（MSI-H）状态。根据MMR状态，在无病生存期或总生存期方面未发现显著差异。此外，在MSI-H组中，辅助化疗的使用与生存结果之间未发现关联。在多因素生存分析中，原发肿瘤位置（右侧与左侧，风险比[HR]=0.172，p=0.003）和T分期（HR=4.764，p=0.005）被确定为无病生存期的独立预后因素。
本研究发现，MMR状态在高危II期CC患者中既不是预后因素也不是预测因素。
