Top Line: Inoperable early-stage lung cancer is a primary indication for radiation in community practices across the nation.
The Study: A major barrier to routine streamlines of care is that the lung is one of the most risky biopsy sites in the body, particularly for populations at risk of lung cancer (think bullous emphysema). This topic discussion delves into best practices for oncologic management of a radiographic diagnosis of early-stage lung cancer. The first decision point is when radiographic suspicion is high enough to merit intervention. Once this threshold is reached, a determination must be made whether to attempt histologic confirmation versus empirically treat with radiation. The crux of the issue is that, absent readily-available advanced navigational bronchoscopy techniques, percutaneous CT-guided biopsies of peripheral early-stage lung cancers can carry many-fold times the risk of simply beaming on. The authors provide a straightforward framework for when to deem clinical risk of malignancy high enough to feel confident proceeding with straight-forward definition SBRT sans biopsy, as well as noting red flag situations.
TBL: “Ultimately, radiation oncologists can feel comfortable proceeding with empiric treatment for most growing solid peripheral lesions with both a high risk of biopsy and a high calculated risk of malignancy without a formal multidisciplinary discussion.” | Dover, Pract Radiat Oncol 2024
