[Radical surgery using modified open door method for anterior apical tumor].

The approach that should be used for an anterior apical tumor still remains controversial. Since a modified open door method was very useful for the widening of the surgical field in a recent patient with an anterior apical tumor, an outline of this case is reported. The patient was a 66-year-old male with squamous cell carcinoma of the anterior apical region of the right lung (suspected to be invading the thoracic wall, cT3N1M0). After a midline sternal incision with a right unilateral collar incision, the medial half of the right clavicle and a few cm of the right 1st rib on the sternal side were resected to sufficiently expose the area from the right brachiocephalic trunk to around the subclavicular artery and vein, where invasion was suspected. This treatment facilitated widening of the visual field around the site of tumor invasion and made safe right upper lobectomy + combined thoracic wall resection + ND2a possible. In this patient, anterolateral incision at the 4th intercostal level, which is made using the original open door method, could be avoided, probably minimizing surgical invasion.
