近年来,临床实践证明对口腔癌的治疗,采用放疗、化疗和手术的综合疗法,疗效远较单一的治疗为优越。化疗作为术前治疗,可以使不能手术的病变缩小,为手术治疗创造条件,且较术前放疗具有更多的优越性,如放疗后局部组织血运差,伤口愈合延迟等。化疗不但无上述缺点,还可减低癌细胞活力,减 In recent years, clinical practice has proved that the treatment of oral cancer uses radiotherapy, chemotherapy, and surgery combined therapy, and the curative effect is superior to that of a single treatment. Chemotherapy as a preoperative treatment can reduce inoperable lesions, create conditions for surgical treatment, and has more advantages than preoperative radiotherapy, such as poor local blood supply after radiotherapy, delayed wound healing and so on. Chemotherapy not only does not have the above-mentioned shortcomings, but also reduces cancer cell activity.
