直肠癌根治术后会复发吗 谢彪 湖南中医药大学第二附属医院（湖南省中医院）

直肠癌根治术后会复发吗 谢彪 湖南中医药大学第二附属医院（湖南省中医院） 直肠癌手术以后，仍有30%的一期到三期的结直肠癌患者容易复发。单因素分析，复发其实跟肿瘤的TNM分期密切相关，如果患者手术以后T分期到了T3、T4，就容易复发，T1、T2相对来说复发率是很低；如果出现了N转移，就是淋巴结的转移，N1和N2就大大增加了复发率，跟肿瘤的分化程度有一定的关系，高分化直肠癌分为高分化、中分化、低分化和未分化，还有一些粘液细胞癌肿瘤的程度是比较高的，术后进行放化疗治疗效果不明显，这种病人容易复发，淋巴结的脉管的侵犯、脉管的侵犯以及神经的侵犯跟淋巴结的转移率是密切相关的。所以复发是一个综合性因素，有一些患者虽然是很早到了T2，在临床上也会看到有些病人很早出现了转移及复发，可能跟患者的肿瘤细胞学、生物学性质有关系。 Will rectal cancer recur after radical operation After surgery for rectal cancer, There are still 30% of patients with stage I to stage III colorectal cancer are prone to relapse. Single factor analysis, Recurrence is closely related to TNM stage, If the patient has T stage to T3 and T4 after operation, It's easy to relapse, The recurrence rate of T1 and T2 was very low; If there is an N transfer, It's lymph node metastasis, N1 and N2 significantly increased the recurrence rate, It is related to the degree of tumor differentiation, Highly differentiated rectal cancer is divided into highly differentiated, moderately differentiated, poorly differentiated and undifferentiated, There are also some mucinous cell carcinoma with high degree, The effect of radiotherapy and chemotherapy is not obvious, This kind of patient is easy to recur, Vascular invasion, vascular invasion and nerve invasion of lymph nodes are closely related to lymph node metastasis rate. So relapse is a comprehensive factor, Some patients arrive at T2 early, In clinical practice, some patients have metastasis and relapse early, It may be related to the cytology and biological properties of the tumor.
