Early stage LUng cancer and DYspnea - The ELUDY study

ELUDY (Early stage LUng cancer and DYspnea) is a prospective study on dyspnea in patients with early stage lung cancer. It will include 14-20 patients that have had surgical resection for non-small cell lung cancer and they will do a cardiopulmonary exercise test (CPET) before and 6 monts after the resection as well as answer questionnaires. The primary endpoint is the difference in dyspnea intensity score (Borg CR10 scale) during CPET pre and postoperatively. Secondary endpoint include dyspnea at rest as well as other CPET variables.
