Follow-up
PATHOLOGY, RECURRENCE
At the time of writing, the longest follow-up time has been 19 months, with a median follow-up time of 9.5 months. At present, observation of all patients is ongoing, and 1 patient suffered a recurrence of regional lymph node during the follow-up. The recurrence case had a surgical pathology showed an incomplete post-treatment pathological response, and there were >90% clinical residual lesions. After surgery, chemoradiotherapy was performed. Local-regional lymph node lesions recurred 6 months after follow-up. These were treated with chemotherapy, resulting in a one-year disease-free survival rate of 95.5%. The long-term therapeutic effects and the correlations between pathological response rates and patients’ condition before treatment and therapeutic effects require validation by further follow-up data (Swimming plot of disease-free survival for individual patients.Fi-VC, Fixed vocal cord; pCR, Pathological complete response; MPR, Major pathological response; IPR, Incomplete pathological response.
