However, tumor sizes larger than 7.5 mm (HR = 1.37; p = 0.257) and surgical approaches, such as minimally invasive thyroidectomy (HR = 1.45, p = 0.233) or RET (HR = 1.31; p = 0.464), are not statistically significant risk factors for post-lobectomy recurrence. This evidence concerns the gene RET and neoplasm.
