INTRODUCTION: Liver metastasis has not been sufficiently evaluated in lung cancer so far. We retrospectively analyzed the distant metastasis of Non-squamous non-small cell lung cancer (NSQ-NSCLC), including liver metastasis, and association between prognosis and therapeutic effect of bevacizumab treatment.
PATIENTS AND METHODS: Clinical data were collected from 1954 patients with lung cancer admitted in our hospital between 1st April 2011 and 31 March 2019. Information is extracted from the electronic medical record. Main collection data was the age, gender, smoking history, performance status, histology and driver mutation, distant metastasis site. Efficacy data of treatment including treatment duration and survival time were obtained from medical record, image data and local registry.
RESULTS: Total 366 patients receiving any chemotherapy with NSQ-NSCLC were eligible for this study. Most frequent extrathoracic metastasis is bone (N = 59) followed by brain (37), liver (18), adrenal gland (23), and OS analysis showed liver metastasis was worse prognosis compared to brain and bone metastasis (median OS: 11.6, 18.9, 15.0, respectively). Bevacizumab treatment was tend to have favorable efficacy in patients with each metastatic sites, especially, induced significant longer OS for patients with liver metastasis. CONCLUSION;: Though this study was retrospective study for small sized metastatic patients, the study suggested that liver metastasis was refractory, and that bevacizumab treatment might improve the worse prognosis.
