Can lung surgery improve survival rates for metastatic breast cancer?

Patients with primary breast cancer that has spread to the lungs may live longer if the lung metastases are surgically removed, according to a study published in The Annals of Thoracic Surgery.

Metastatic breast cancer (mBC) is a stage identified when the disease has spread to distant, nonadjacent organs or areas. The median survival of patients with mBC treated with conventional chemotherapeutic regimens ranges from 12 to 24 months. Previously, it had been assumed that these patients would not benefit from surgical intervention.

The researchers found that, with metastasectomy, the median overall survival increased to as much as 103.4 months.
