Thus, the current pilot study aimed to evaluate the efficacy and safety of CSM-TACE in treating HNC. Methods: A total of 15 HNC patients receiving CSM-TACE at the Second Affiliated Hospital of Dalian Medical University from March 2017 to December 2021 were enrolled. Moreover, treatment information, treatment response, progression-free survival (PFS), overall survival (OS), change of liver and renal function indexes, adverse events were recorded. Results: There were 9 patients receiving CSM-TACE as first line and 6 patients receiving CSM-TACE as second or above line treatment; meanwhile, there were 7, 7 and 1 patients undergoing 1 time, 2 times and 3 times of CSM-TACE, respectively. Furthermore, objective response rate (ORR) and disease-control rate (DCR) were 60.0% and 100%, respectively at 1st month; meanwhile, ORR and DCR were 53.3% and 73.3%, accordingly at 2nd month. Moreover, 1-year PFS rate was 34.1%; besides, 1-year OS rate was 38.9%. Additionally, no change of liver function indexes (including TP, ALB, TBIL, ALT and AST) or renal function indexes (including Cr and BUN) was found before and one month after treatment (all P>0.05). Meanwhile, no severe adverse event was found during and after CSM-TACE. Conclusion: CSM-TACE illustrates favorable treatment response and survival benefit, as well as tolerable safety profile in HNC patients.
