Minimally invasive resection of benign esophageal tumors is technically safe and associated with a shorter length of stay compared with open approaches. Although no specific cutoff for size could be identified, most tumors greater than 7 cm were removed by thoracotomy. The subsequent development of reflux may be related to the esophageal myotomy required for resection.

High VEGF expression within stage I NSCLC is closely associated with high intratumoral angiogenesis and poor prognosis. Immunohistochemical evaluation of T stage and VEGF expression along with examination of angiolymphatic invasion perioperatively may aid in predicting prognosis. Adjuvant therapies aimed at retarding tumor angiogenesis may be considered for stage I NSCLC patients with high VEGF levels.
