    • Abstract

    Background:
    An increasing interest is seen in the role of preoperative physical function and activity in enhancing postoperative recovery. But, the short-term effect of preoperative physical activity (PA) on recovery after lung cancer surgery is unknown. The purpose of this study was to compare the difference of physical function and activity between General elderly and lung cancer patients before surgery. Also, we compared post-operative Cardiorespiratory fitness (CRF) according to preoperative PA level.
    
    Method:
    Lung cancer patients of this study consisted of patients who were registered for lung cancer cohort. Patients of cohort included were those scheduled to undergo lung cancer surgery, at participating hospitals in the Seoul of South Korea. We are selected a total 69 elderly lung cancer patients in cohort patients. Exclusion criteria of a cohorts of lung cancer study included ECOG PS >1 and neoadjuvant therapy, Multiple cancer, recurrent lung cancer. Patients planned for lung cancer surgery filled out a questionnaire and perform before, as well as at 3 weeks after the operation. Also, we selected 69 general elderly by matching the gender and age, at users of Seniors Welfare Center in Seoul of South Korea. The physical function test included muscle strength, gait ability, and cardiorespiratory fitness (6-minute walk test). PA was assessed using the self-reported short form IPAQ questionnaires.
    
    Result:
    Preoperatively, No difference was seen CRF and PA between General elderly and lung cancer patients before surgery. More active lung cancer patients (MVPA>150min) had higher CRF at 3 weeks after surgery (p<.002*) than inactivity lung cancer patients. Table 1.

    Conclusion:
    The preoperative physical function of elderly lung cancer patients is not different from general elderly, but physical activity is very low. Also, Regular and increase physical activity before surgery with elderly lung cancer has been associated with CRF after surgery.
