This retrospective study investigated the effectiveness of additional resection of the invasive cancer PM under different levels of preoperative carbohydrate antigen 19-9 (CA19-9). Methods: Patients who underwent hepatectomy for HCCA from 2000 to 2017 were analyzed. Surgical variables, resection margin status, length of the PM (LPM), prognostic factors, and survival were evaluated. Results: A total of 228 patients were enrolled: 175 PM(−) without additional resection patients (group A), 21 PM(−) after additional resection (group B), 16 PM(+) without additional resection (group C), and 16 PM(+) after additional resection (group D). The median survival of group B (20.99 months) was similar to that of group A (23.00 months; P=0.16), and both were significantly better than those of group C (11.60 months) and D (9.50 months), especially when preoperative CA19-9>150 U/mL (P10 mm was significantly better compared with those with an LPM ≤10 mm, especially when preoperative CA19-9 was >150 U/ml (P10 mm group, the survival of group B was comparable with that of group A (P>0.05). Conclusions: HCCA patients could get a survival benefit from a negative PM resulting from additional resection. Survival could be comparable with that of negative PM without additional resection among HCCA patients. An LPM >10 mm is possibly more associated with better survival compared with whether additional resection of the positive PM is performed under different levels of preoperative CA19-9.
