CHCC-CC, TUMOR, RECURRENCE
Early recurrence was defined as the occurrence of a new tumor within a year after radical resection of cHCC-CC. The starting point was the day of the operation, while the endpoint was the detection of intra- and extra-hepatic recurrence within a year post-surgery. All cHCC-CC patients were regularly monitored for 12 months after operation. Within the first six months post-surgery, monthly re-examinations were conducted. Afterward, re-examinations were scheduled every three to 6 months. The routine follow-up protocols include imaging examinations such as CT and MRI and US, and tumor markers such as serum AFP, abnormal prothrombin, AFP-L3, and other tumor markers. If new liver lesions were detected through imaging examinations like ultrasound, CT, MRI or confirmed through puncture or surgical pathological examination, the follow-up ended. The deadline of follow-up was January 31, 2023.
