Risk factors and survival outcomes in patients with breast cancer and lung metastasis: a population ‐based study

In conclusion, the incidence and prognosis of BCLM varied by tumor subtypes, age, and race. Elderly patients with HER2‐positive or triple‐negative tumors were more likely to have BCLM. The aim of this study was to assess the incidence and survival in patients with breast cancer and lung metastases (BCLM) and associated risk factors on a population level. Of the 11,568 patients with stage IV breast cancer, 4213 (36.42%) had BCLM and 1214 (10.49%) had BCLM confined to lungs. Survival analysis showed that the aged, black race, HR−/HER2+, triple‐negative subtype, higher grade were the independent risk factor for BCLM patients’ survival, while HR+/HER2+ subtype, insured status, and married status suggested better prognosis.
