RT Journal Article SR Electronic T1 Preliminary results of first year of application of cardiopulmonary exercise test (CPET) in resection lung surgery in Navarra (Spain) JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P2763 VO 44 IS Suppl 58 A1 Sonia Herrero A1 Vanessa López A1 Amparo Urrizburu A1 María Jesús Martínez A1 José Javier Lorza A1 Juan José Guelbenzu A1 Xenia López A1 Pilar Cebollero YR 2014 UL http://erj.ersjournals.com/content/44/Suppl_58/P2763.abstract AB 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<80%), in 30 patients due to FEV1<80, in 46 due to DLCO<80 and in 24 due to both factors.Using the previous protocol (ppoFEV1 or ppoDLCO<40%) we should use it in only 13 patients. The main functional data were: FEV1 78%(33-113), DLCO 64%(39-106), VO2% 92,4 (63-119), VO2/kg/min 21.6. Five cases were contraindicated for surgery and another patient refused intervention. Of these five, two cases shouldn´t be contraindicated with previous protocol.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.
