Abstract
Objective: To investigate the value of planned neck dissection combined with induction chemotherapy and concurrent chemoradiotherapy in regional control and the outcome of locally advanced head and neck squamous cell carcinoma. Methods: A prospective randomized controlled study totally enrolled sixty-four patients of head and neck squamous cellcarcinomas(include oropharynx, hypopharynx, and larynx) in stages Ⅳa-Ⅳb with lymph node metastase was were N2-N3. All patients firstly received 2-3 cycles of induction chemotherapy(ICT), then divided into two groups randomly, according to the efficacy of ICT. Group A(the study group) received planned neck dissection(PND) and concurrent chemoradiotherapy(CCRT). Group B(the control group) received concurrent chemoradiotherapy(CCRT). The differences in clinicopathologic features, local recurrence(LR), regional recurrence(RR), disease-free survival(DFS), and overall survival(OS) between the two groups were estimated. SPSS 19.0 software was used to analyze the data. Results:Group A enrolled twenty-one patients, and group B enrolled forty-three patients.The follow-up of all patients were 4-55 months, median follow-up time was 22 months. In study group, two-year OS and DFS were 80.9% and 68.3%, respectively. In control group, two-year OS and DFS were 90.7% and 67.1%, respectively. There was no significant difference in gender(P=0.215), age(P=0.828), primary tumor site(P=0.927), LR(P=0.126), DFS(P=0.710), and OS(P=0.402) between the two groups, while the RR(χ(2)=5.640, P<0.05) and distant metastasis(χ(2)=10.363, P<0.01) showed significant differences between the two groups. Conclusion: The ICT+ PND+ CCRT treatment model has benefit on regional control of locally advanced head and neck squamous cell carcinoma.
