The efficacy of neoadjuvant therapy for recurrence after hepatectomy for hepatocellular carcinoma is still unclear. We report a case of recurrent massive advanced hepatocellular carcinoma with pathological complete remission was treated by continuous hepatic arterial infusion chemotherapy (HAIC) and sequential transcatheter arterial embolization (TAE) combined with secondary operation. One month after resection, the patient recurred (massive type 141mm× 76mm). After 4 times of HAIC sequential TAE conversion therapy, the tumor shrank significantly (70mm× 29mm), alpha-fetoprotein(AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA-II) levels decreased significantly, residual liver volume[left half liver accounted for 39.85% of standard liver volume(left half liver + right anterior lobe) accounted for 80.17% of standard liver volume] and Indocyanine green 15-minute retention(ICG R15 8.0%) complies with surgical requirement.The second operation was performed, and the tumor was completely resected after hepatic blood flow occlusion Requirement. The postoperative pathological results showed complete remission (PCR) of the tumor, and no recurrence was found during the follow-up of 16 months. In this case, HAIC sequential TAE conversion therapy has good short-term effect on patients with postoperative recurrence of hepatocellular carcinoma, tumor burden is significantly reduced, the second surgery pathology achieves complete remission, safety and tolerance, it is worthy of study and promotion.Keywords: hepatocellular carcinoma, recurrence after resection, two-stage hepatectomy, complete remission, sequential therapy
