Abstrakt: Background and Aims: Surgical resection is the primary treatment for HCC; however, it is associated with a high rate of recurrence and death. We conducted this phase 2 study to investigate the efficacy and safety of postoperative intensity-modulated radiotherapy (IMRT) for HCC after narrow-margin hepatectomy.
Approach and Results: We designed a single-arm, prospective phase 2 trial to evaluate overall survival (OS), disease-free survival (DFS), recurrence patterns, and toxicity in patients receiving adjuvant radiotherapy. The eligibility criteria included the following: pathological diagnosis of HCC after hepatectomy, with narrow pathological margins (< 1 cm); age > 18 years; and Eastern Cooperative Oncology Group performance status score of 0 or 1. Patients received IMRT within 4-6 weeks after surgical resection. This trial was registered at ClinicalTrials.gov (NCT01456156). Between 2008 and 2016, a total of 76 eligible patients who underwent narrow-margin resection were enrolled. The median follow-up duration was 70 months; the 3-year OS and DFS rates were 88.2% and 68.1%, respectively; and the 5-year OS and DFS rates were 72.2% and 51.6%, respectively. Intrahepatic recurrence was the primary recurrence pattern. No marginal recurrence was found. Intrahepatic, extrahepatic, and combined recurrences at the first relapse were found in 33, 5, and 1 patient, respectively. The most common radiation-related grade-3 toxicities were leukopenia (7.9%), elevated alanine aminotransferase (3.9%) and aspartate aminotransferase (2.6%) levels, and thrombocytopenia (1.3%). Classical or nonclassical radiation-induced liver disease was not noted.
Conclusions: Adjuvant radiotherapy is an effective, well-tolerated, and promising adjuvant regimen in patients with HCC who have undergone narrow-margin hepatectomy. Our trial provides evidence and a rationale for planning a future phase 3 trial.
