Treatment of central type lung cancer by combined cryotherapy: Experiences of 47 patients

Abstract Most patients with central type lung cancer (CTLC) are not candidates for surgery; systemic chemotherapy and external beam radiotherapy are the main treatments but have not greatly affected patient outcome. Combined percutaneous and endobronchial cryotherapy has been used successfully to treat CTLC; this study aimed to determine its feasibility and safety. Forty-seven patients with unresectable CTLC (22 endotracheal, 26 tracheal wall and 21 extratracheal tumors) underwent 69 sessions of combined percutaneous cryosurgery, endobronchial cryosurgery and airway stenting. The long diameter of all tumors was P P P P
