[Effect of endoscopic surgery combined with chemotherapy and radiotherapy on prognosis of early nasopharyngeal carcinoma patients in high incidence area].

ABSTRACT

Objective:To investigate the differences in the therapeutic effects of endoscopic surgery combined with chemotherapy and endoscopic surgery combined with radiotherapy in the treatment of early nasopharyngeal carcinoma, and to select individualized treatment strategy for early nasopharyngeal carcinoma. Methods:The clinical data of 68 patients with early nasopharyngeal carcinoma（T1-2N0M0） who received surgical treatment in a high-incidence area were retrospectively analyzed. According to different treatment methods, they were divided into the surgery + chemotherapy group（n=34, treated with endoscopic surgery combined with chemotherapy） and the surgery + radiotherapy group（n=34, treated with endoscopic surgery combined with radiotherapy）. Propensity score matching was used to match the patient data between the two groups at a 1∶1 ratio. Patients were followed up, and the survival rates and hematological toxicities were compared between the two groups. Results:Twenty-four cases in the surgery + chemotherapy group and 24 cases in the surgery + radiotherapy group were successfully matched. After matching, there was no statistically significant difference in T stage, and clinical stage between the two groups（all P>0.05）. The 3-year OS and DFS in the surgery + chemotherapy group were 100.0% and 95.8%, respectively, while the 3-year OS and DFS in the surgery + radiotherapy group were 100.0% and 100.0%, respectively, with no significant difference in survival rates between the two groups（both P>0.05）. After treatment, there was no statistically significant difference in bone marrow suppression between the surgery + chemotherapy group and the surgery + radiotherapy group （all P> 0.05） Conclusion:Endoscopic surgery combined with chemotherapy and surgery combined with radiotherapy have comparable clinical efficacy in the treatment of early nasopharyngeal carcinoma, but without radiotherapy-related complications, which is worth further investigation.
