Annals of Surgical Oncology, Kobayashi et al. present the survival of 392 patients who developed intrahepatic recurrence after initial curative-intent hepatectomy for colorectal liver metastases (CLM) from 2006 to 2020 at a single high-volume institution in Japan.
1 Patients who underwent repeat hepatectomy had a significantly longer survival compared with those who did not undergo resection (5-year overall survival [OS] from initial liver resection, 66.3% vs. 27.2%;
p < 0.001). The authors identified three predictors of poor prognosis for patients with recurrent CLM: ≥4 recurrent tumors, tumor size ≥5 cm, and presence of extrahepatic disease. These three factors were consolidated to stratify recurrent CLM into resectable versus borderline resectable versus unresectable categories, each with distinct prognoses (5-year OS: 67.3% vs. 30.8% vs. 2.6%). …
