Preliminary results of first year of application of cardiopulmonary exercise test (CPET) in resection lung surgery in Navarra (Spain)

AIM: analyse the clinical and functional results during the first year of application of the ERS/ESTS guidelines on fitness for radical therapy in lung cancer (LC) patients. Methods: prospective analysis of data of those patients proposed to surgical treatment for LC. We analysed pre FEV1, DLCO, VO2%, VO2/kg/min , complications in the first 30 days, mortality at 6 months and six months postFEV1, DLCO, VO2%, VO2/kg/min when available. Results: during 2013,103 patients were proposed to surgical treatment because of LC .All of them were evaluated with FEV1 and DLCO. Of them, 52 needed a CPET (ERS/ESTS guidelines: FEV1 or DLCO 8 complications were registered in first 30 days, three of them moderate. 2 deaths in six months not related to surgery were found. In 12 patients we made a second CPET six months after surgery. Only VO2/kg/min showed a significant difference (p=0.02) Conclusions: -We could apply ERS/ESTS guideline to 100% of our patients -The main cause of CPET indication was impaired DLCO -Half of cases proposed for surgery needed CPET, much more than those if we use previous protocol -we only found deterioration in VO2/k/min but our sample is still small.
