ABSTRACT
Objective@#Using propensity score matching method (PSM) to investigate the clinical effect of postoperative adjuvant radiotherapy and postoperative concurrent chemoradiotherapy for locally advanced hypopharyngeal squamous cell carcinoma.@*Methods@#From July 2007 to July 2018,174 postoperative patients with locally advanced hypopharyngeal squamous cell carcinoma were enrolled in pre-PSM cohort, including 168 males and 6 females, the median age was 60 years old (ranged from 37 to 79 years old).Loco-regional control (LRC),progression-free survival (PFS) and overall survival (OS) were compared and analyzed between the patients treated with postoperative adjuvant radiotherapy and postoperative concurrent chemoradiotherapy (cisplatin was given in a dose of 80 mg/m2 on days 1, 22, and 43). After the propensity score matching (PSM), 61 sub-pairs of 122 patients were generated in post-PSM cohort. Survival rate were assessed with Kaplan-Meier method and Log-rank test.@*Results@#After the propensity score matching(PSM), 61 sub-pairs of 122 patients were generated in post-PSM cohort.The patients were followed up for 3-135 months, the median follow-up was 42 months. No significant differences in 3-year and 5-year LRC, PFS, OS were observed between the two groups (P>0.05) . For postoperative patients who had high-risk factors (extracapsular extension of nodal disease, and/or vascular embolism, and/or lymph node metastasis≥2, and/or positive surgical margin, and/or perineural infiltration),there were significant differences between the two groups in 3-year PFS (60.99% vs 84.49%,P<0.05), 5-year PFS (35.47% vs 56.97%,P<0.05) and 5-year LRC (41.02% vs 68.50%, P<0.05), but no significant difference was found in OS between the two groups (P>0.05).@*Conclusion@#Postoperative concurrent chemoradiotherapy was more efficacious than postoperative radiotherapy alone in terms of loco-regional control and PFS for high-risk postoperative patients with locally advanced hypopharyngeal squamous cell carcinoma.
