Evaluation of the up-to-7 criterion for determining the treatment of hepatocellular carcinoma in Barcelona Clinic Liver Cancer stage B: a single-center retrospective cohort study

[摘要] Background: At present, there are still disputes on the treatment of surgery for patients with stage B hepatocellular carcinoma (HCC). This study sought to investigate whether the up-to-7 criterion could be used to decide the treatment for HCC in Barcelona Clinic Liver Cancer stage B (BCLC-B). Methods: We analyzed 340 patients with HCC in BCLC-B who treated with hepatectomy or transcatheter arterial chemoembolization (TACE). Of the 285 HCC patients who underwent hepatectomy, 108 met the up-to-7 criterion and 177 exceeded it. All 55 patients in the TACE group met the up-to-7 criterion. We obtained the tumor status of the patients through inpatient medical records, outpatient medical records, and telephone follow-up of the hospital. We compared overall survival (OS) and progression-free survival (PFS) were compared between patients who met the up-to-7 criterion and who underwent either hepatectomy or TACE. OS and recurrence time were also compared between the patients who were treated with hepatectomy and who either met or exceeded the up-to-7 criterion. Across BCLC-B patients, we compared the OS of patients after surgical treatment between subgroups stratified by tumor number and diameter. Results: Patients who met the up-to-7 criterion had significantly higher OS rates after hepatectomy than TACE (P3 tumors (P=0.001). When we stratified patients with ≤3 tumors based in whether they met or exceeded the up-to-8 to up-to-15 criterion, OS was significantly better among those who met the criterion in all cases. Conclusions: Hepatectomy appears to be associated with better survival than TACE in patients with BCLC-B HCC who meet the up-to-7 criterion, but this criterion is not a strict indication for deciding whether to treat patients with BCLC-B surgically. Tumor number strongly affects the prognosis of BCLC-B patients after hepatectomy.
