BACKGROUND: For advanced pancreatic cancer, pulmonary metastases (PM) have been considered favorable factors compared to metastases of other sites, but it remains unknown whether the prognosis of patients with synchronous liver and lung metastases is better than that of non-PM.
METHODS: Data was derived from a two-decade cohort and included 932 cases of pancreatic adenocarcinoma with synchronous liver metastases (PACLM). Propensity score matching (PSM) was applied to balance 360 selected cases, grouped into PM (n = 90) and non-PM (n = 270). Overall survival (OS) and survival-related factors were analyzed.
RESULTS: In PSM-adjusted data, the median OS was 7.3 and 5.8 months, for PM and non-PM, respectively (p = 0.16). Multivariate analysis revealed that male gender, poor performance status, higher hepatic tumor burden, ascites, elevated carbohydrate antigen 19-9, and lactate dehydrogenase were factors of poor survival (p < 0.05). Chemotherapy was the only independent significant factor of favorable prognosis (p < 0.05).
CONCLUSION: Although lung involvement was indicated to be a favorable prognostic factor for patients with PACLM in the whole cohort, PM were not associated with better survivals in the subset of cases subjected to PSM adjustment.
