为了提高舌癌口底癌手术疗效，作者对４７例施行保持下颌骨连续性的舌癌口底癌联合根治术的复发因素进行分析。结果显示：术后复发１４例，复发率为２９．８％。局部复发均在原发灶的内侧软组织。９例舌侧缘口底后部癌中有５例复发（５５．６％），而５例舌侧缘前部癌中无１例复发，两者比较有显著性差异（Ｐ＜０．０５）；Ｔ３～４复发率（４８．０％）明显高于Ｔ１～２复发率（９．１％），Ｐ＜０．０１；有同侧颈淋巴结转移者的复发率（５４．５％）高于无颈淋巴结转移者的复发率（２２．２）％，Ｐ＜０．０５。作者认为：对适应证恰当的病例，术后复发与保持下颌骨连续性无关，而与肿瘤原发部位、大小、颈淋巴结转移及切除范围有关。
In order to improve the curative effect of mouth cancer of mouth cancer, the authors analyzed the recurrence of 47 cases of tongue cancer combined with radical mastectomy for mandibular continuity. The results showed that: postoperative recurrence in 14 cases, the recurrence rate was 29.8%. Local recurrence is in the primary tumor of the medial soft tissue. There were 5 cases (55.6%) of the 9 cases with posterior border cancer of the lingual margin, and 5 cases had no recurrence in the frontal cancer of tongue. There was significant difference between the two groups (P <0.05) ). The recurrence rate of T3 ~ 4 (48.0%) was significantly higher than that of T1 ~ 2 (9.1%), P <0.01. The recurrence rate of patients with ipsilateral cervical lymph node metastasis (54.5% The recurrence rate was higher than those without cervical lymph node metastasis (22.2%), P <0.05. The authors believe that: the appropriate indications of the cases, postoperative recurrence and maintain the continuity of the mandible has nothing to do, but with the primary tumor location, size, cervical lymph node metastasis and resection range.
