EP07.01-21 A 22 to 23G Intraoperative Needle Biopsy Does Not Affect Recurrence of Preoperatively Undiagnosed Stage 1 Lung Cancer

The pathological diagnosis of cancer is essential to determine the surgical approach for lung resection surgery; however, the diagnostic rates of a transbronchial lung biopsy for peripheral small-sized lung cancer range from 18% to 62%. Therefore, an intraoperative needle biopsy (INB) is often performed for preoperatively undiagnosed lung lesions, even though this aspiration technique carries a potential risk of dissemination or recurrence. However, the precise impact of an INB on recurrence remains controversial, as both the needle size and clinicopathological factors are associated with recurrence (tumor size, lymphovascular invasion, pleural invasion, and EGFR mutation status).
