BackgroundParticipation in housework and meal preparation are instrumental activity of daily living (IADL) evaluation items that is known to predict prognosis and complications in cancer care. However, these items are often assessed only for females, not for males, in IADL.MethodsWe examined the impact of habit of housework and meal preparation on overall survival (OS) in 1025 Japanese male patients who underwent elective urologic cancer surgery at our institution. The study also used a cohort that was matched by propensity score.ResultsWe found that patients who did not prepare meals or do housework had significantly shorter OS (hazard ratio [HR] = 3.34, P = 0.005; HR = 5.01, P < 0.001, respectively). Even in the cohort of 448 patients matched by propensity score and adjusted for age, body mass index, comorbidities, performance status, living status, cancer type, stage groups of cancer, and surgical approach, lack of participation in housework was associated with shorter OS (HR = 2.92, P = 0.04) and was an independent predictor of worse OS in multivariable analysis (HR = 5.13, P = 0.008).ConclusionsMales who did not regularly do household chores before elective cancer surgery had worse life outcomes. Doing more daily physical activities, such as household chores like making the bed and cleaning the room, might have a positive impact on survival when fighting cancer.Copyright © 2024 Elsevier Inc.
