Efficacy analysis of sequential surgery after the DCF scheme induction chemotherapy in T2-3 laryngeal carcinoma and hypopharyngeal carcinoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study clinical efficacy of surgery after the DCF induction chemotherapy in T2-3 laryngeal carcinoma and hypopharyngeal carcinoma.@*METHOD@#To analyze clinical data about 102 cases of T2-3 laryngeal carcinoma and hypopharyngeal carcinoma retrospectively, 62 cases were divided into experimental group and 40 cases in control group, the experimental group completed three cycles of the DCF induction chemotherapy, then the efficacy was evaluated, surgery were carried out in the end, the control group received operation directly. In two groups, tumor response rates, toxicities, positive surgical margin rates and survival rate differences were observed and compared.@*RESULT@#Tumor response rate was 61.3% in experimental group, the laryngeal carcinoma rate was significantly lower than that in hypopharyngeal (44.4% VS 84.6%, P 0.05). The foci edges of 0. 3 cm and 0. 5 cm positive margin rate of hypopharyngeal carcinoma in experimental group were significantly lower than in its control (P 0.05). During induction chemotherapy in the experimental group, no serious adverse reactions were found.@*CONCLUSION@#Induction chemotherapy of DCF regimen can not only narrow T2-3 laryngeal carcinoma and hypopharyngeal carcinoma' area, but also ensure an adequate safety margin.
