[Surgical treatment for Pancoast tumors--significance of surgical approach and induction chemoradiotherapy].

ABSTRACT

We analyzed 46 patients with Pancoast tumor who underwent surgical resection. Anterior approach was employed for 16 patients and hook approach for 30 patients. Twenty-one patients received preoperative treatment; chemotherapy for 1 patient, radiotherapy for 11 patients, and chemoradiotherapy for 9 patients. Complete resection was achieved in 59% (27/46) of patients. The overall 5-year survival rate was 10.9%. Five-year survival was significantly higher in the patients received complete resection than the patients received incomplete resection (18.5 vs 0%, p=0.0016). The complete resection rate has improved in recent cases, and one of the reasons seems to be the adoption of preoperative chemoradiotherapy. But postoperative complications occurred more frequently in patients who received induction therapy than the others. Optimal selection of surgical approach and induction chemoradiotherapy for Pancoast tumors appear to provide improved complete resection rate and long term survival.
