目的   分析贝伐珠单抗与化疗对晚期结直肠癌患者4种错配修复蛋白（MSH2、MLHI、MSH6、PMS2）水平影响。方法   选择2022年1月—2024年1月江苏省宿迁市中医院肿瘤科102例晚期结直肠癌患者，按抽签法分成两组，即化疗组及联合组，各51例。化疗组应用FOLFOX（亚叶酸钙+奥沙利铂+氟尿嘧啶）方案进行化疗，联合组采取贝伐珠单抗联合FOLFOX方案治疗。对比其肿瘤控制效果、免疫功能及MSH2、MLHI、MSH6和PMS2水平变化，并对比组间不良反应发生率。结果   联合组客观缓解率、疾病控制率高于化疗组（P＜0.05）；治疗后联合组患者CD4⁺ 、CD3⁺ 、CD8⁺ 、和CD4⁺ /CD8⁺数值高于化疗组，且两组治疗后均低于治疗前（P＜0.05）；治疗后两组患者MSH2、MLHI、MSH6和PMS2缺失率对比无统计学意义（P＞0.05），但其阳性、阴性表达情况对比差异有统计学意义，联合组MSH2、MLHI、MSH6和PMS2阳性率低于化疗组（P＜0.05）；两组不良反应发生率对比差异无统计学意义（P＞0.05）。结论   对晚期结直肠癌在化疗基础上增加贝伐珠单抗抗肿瘤效果显著，改善其免疫功能，虽无法改善患者错配修复蛋白缺损，但可辅助降低其阳性率，且不影响安全性。
