ABSTRACT
BACKGROUND:
In an era of more effective chemotherapy for pancreatic ductal adenocarcinoma (PDAC), the paradigm of local treatment is changing. However, the efficacy of local treatment in patients with isolated liver metastasis remains unclear. Therefore, we aimed to evaluate the effectiveness of pancreatectomy ± local treatment for metastasis (cytoreductive surgery) in PDAC patients with isolated synchronous liver metastasis.METHODS:
In total, 239 patients with isolated liver metastasis were extracted from Seoul National University Hospital (SNUH). For comparison, another 12 637 patients were extracted from the National Cancer Database (NCDB). Propensity score matching was performed to minimize confounding in both cohorts. Survival analyses stratified by the treatment delivered were performed using Kaplan-Meier estimates and log-rank tests.RESULTS:
In the SNUH cohort, the median (interquartile range) survival was 20.5 (13.0-42.0) months for patients who underwent cytoreductive surgery plus chemotherapy versus 12.0 (10.0-18.0) months for those who received chemotherapy alone (P < .001). With the NCDB cohort, the median (interquartile range) survival was 15.6 (8.9-31.2) months for patients who underwent cytoreductive surgery plus chemotherapy versus 7.4 (3.4-13.2) months for those who received chemotherapy alone (P < .001).CONCLUSION:
Patients with isolated synchronous liver metastasis should be considered for cytoreductive surgery in addition to effective chemotherapy.Key words
