Extract

Indeterminate peripheral lung lesions that are suspicious for malignancy are ideally treated by surgical resection.1 However, the high false-positive rate of CT scan, especially in lung cancer screening, suggests that in some cases a biopsy is appropriate.2 The clinical suspicion of a benign diagnosis, high surgical risks that render the patient inoperable, and discordance between clinical judgment and imaging tests (eg, negative lesions in smokers on PET scans) are some indications for such a biopsy.1 A histologic diagnosis of malignancy is relevant even in patients who are nonsurgical candidates because of the availability of potentially curative external-beam radiation, stereotactic radiosurgery, and radiofrequency ablation.
