Prognostic factors and survival outcomes according to tumor subtype in patients with breast cancer lung metastases.

ABSTRACT:

Background

Reports on the incidence and prognoses of lung metastases when diagnosing breast cancer patients with different subtypes are limited. Our study investigated the effect of molecular sub-typing stratification on the prognoses of lung metastatic breast caner patients.

Methods

Patients with breast cancer and lung metastases were identified from Surveillance, Epidemiology and End Results population-based data between 2010 and 2015. Univariate and multivariate Cox regression analyses were performed to identify risk factors and prognoses, overall survival (OS) and breast cancer-specific survival for patients with breast cancer lung metastases.

Results

We identified 6,516 patients with lung metastatic breast cancer, representing 1.7% of the entire cohort and 30.4%
