Bevacizumab-induced chronic interstitial pneumonia during maintenance therapy in non-small cell lung cancer. No definitive data on differential cell count although histopathologic findings indicate relatively modest infiltration of alveolar spaces with monocytes and neutrophils. Ideally the bronchoalveolar lavage process samples predominantly cells and material within the airspaces of terminal bronchioles and alveoli. Although it does require anesthesia, with the associated risks in respiratory-compromised patients, bronchoalveolar lavage (BAL) is a minimally-invasive and well-tolerated procedure that lessen the need to proceed to more invasive interventions, such as surgical lung biopsy.
