著者观察口腔、口咽、下咽及喉部恶性肿瘤1584例,上皮癌占96％。62例非上皮性肿瘤局部复发与手术无关, 864例肿痛切除,9％切除不彻底。肿瘤残余率以口腔最高(15％);其次为喉部(4％);下咽部(3％)。肿瘤残余病例之处理方法有三:(1)11例立即二次切除;(2)9例术后放疗;(3)54例未作其他处理。随诊5年,三组病例之2年存活率分别为82％、44％、43％;5年存活率分别为67％、43％、21％。以立即二次切除组效果最好。 607例术后报告切除彻底,肿瘤复发率分别
The authors observed 1584 cases of malignant tumors of the oral cavity, oropharynx, hypopharynx, and larynx, and the epithelial cancer accounted for 96%. Local recurrence of 62 non-epithelial neoplasms was not related to surgery. 864 cases were retired and 9% resection was incomplete. The tumor residual rate was highest in the oral cavity (15%); followed by the larynx (4%); and the hypopharynx (3%). There are three methods for the treatment of residual tumors: (1) immediate resection in 11 cases; (2) postoperative radiotherapy in 9 cases; (3) no treatment in 54 cases. After five years of follow-up, the two-year survival rates for the three groups were 82%, 44%, and 43%, respectively; the 5-year survival rates were 67%, 43%, and 21%, respectively. The immediate effect of the second resection group is best. 607 cases of postoperative resection reported completely, tumor recurrence rate were
