Characteristics of neck lymph node regression in patients with nasopharyngeal carcinoma receiving famitinib and concurrent chemoradiotherapy. The response was measured as the largest percentage reduction in the sum of the longest diameters of target lesions for all assessable patients with a radiographic assessment (n = 20). Response kinetics in patients receiving famitinib a 12.5 or b 16.5 or c 20 or d 25 mg cohort and all the patients (e). Tumours were assessed 2 weeks after taking famitinib (D15), at the end of CCRT and 12 weeks after treatment according to the RECIST (version 1.0) guidelines; horizontal line at − 30% marks the threshold for defining objective response (partial tumour regression) according to RECIST, and a horizontal line at − 20% indicates the threshold for defining progressive disease. f Waterfall plot of best tumour response 2 weeks after taking famitinib (D15). *Indicated that two lines overlapped together
