An Observational Study of Team Management Approach for CapeOX Therapy in Patients with Advanced and Recurrent Colorectal Cancer: SMILE Study (The Study of Metastatic colorectal cancer to investigate the Impact of Learning Effect).

ABSTRACT

OBJECTIVES: In recent years, CapeOX therapy for patients with colorectal cancer is widely used. We previously reported that a multidisciplinary approach decreases the worsening of adverse events and increases patient satisfaction. In this study, we conducted a multicenter, prospective, observational study to evaluate the incidence of adverse events, health-related quality of life (HRQOL) of the patient, and efficacy of a management (intervention) according to the support system (SMILE study). METHODS: As the interventional method, the following more than one method was carried out in each institute, 1 support with telephone, 2 dosing instruction by a pharmacist, 3 skin care instruction by a nurse, and 4 patient instruction by a doctor. The primary endpoint was the incidence of hand-foot syndrome (HFS) of more than grade 2. The secondary endpoint was the HRQOL evaluation and efficacy. The questionnaire (HADS) was administered before the start of the chemotherapy and in 1, 2, 4, 5, and 8 courses to evaluate quality of life (QOL). RESULTS: From April 2011 to September 2012, 80 patients were enrolled from 14 sites, and all patients were the subjects of analysis. The demographic background was as follows man/woman 46/34, age median 63 (36-75), and management interventional method 1/2/3/4 36/68/73/78. The overall percentage of HFS that exceeded grade 2 within 6 months was 16.3%. It was 11.1% with the telephone support group and 20.5% without the telephone support group (p = 0.26). CONCLUSIONS: A multi-professional telephone support may reduce the deterioration of HFS. Further study which includes larger cohort is needed in the future.
