Association between the Preoperative Two-step Score and Postoperative Length of Stay in Patients with Breast Cancer

Abstract

[Purpose] This retrospective study of patients with breast cancer investigated the relationship between preoperative physical function and the postoperative length of stay (LOS). [Participants and Methods] Eighty-two patients with breast cancer who underwent a total mastectomy were divided into a normal LOS group (n=46, postoperative LOS ≤7 days) and a prolonged LOS group (n=36, postoperative LOS >7 days). Demographic data, clinical findings, and motor function were compared between the two groups. Motor function was assessed using tests that measured the risk of impaired mobility due to locomotive syndrome. [Results] Body height, resection of axillary lymph nodes, and the two-step score were significantly associated with a prolonged postoperative LOS. [Conclusion] The results of this study show that a decreased preoperative two-step score was significantly associated with a prolonged LOS. This finding indicates that this test might be useful for predicting longer LOS in patients with breast cancer.
