RESUMO
Background and Objectives: Colorectal cancer (CRC) is a malignant tumor with an extremely high incidence rate worldwide. This study explores the influence of mindfulness-based stress reduction (MBSR) in the care of patients with CRC undergoing bevacizumab (BVZ) plus XELOX chemotherapy, aiming at providing reliable reference and guidance for further improving their rehabilitation and prognosis. Methods: Between January 2019 and March 2020, 88 patients with CRC admitted consecutively to Jiangsu Cancer Hospital in China were enrolled in the study. Of them, 42 patients receiving BVZ plus XELOX chemotherapy, conventional care and MBSR intervention were assigned to the intervention group, and the remaining 46 patients receiving XELOX chemotherapy and conventional care were included in the control group. Clinical efficacy, safety and improvement in functional status were compared. Patients' psychological state, treatment compliance and self-care ability were evaluated. Finally, prognostic quality of life (QoL) was recorded at 1-year follow-up. Results: The overall response rate and incidence of adverse events in the intervention group were not different in the control group, but the total control rate and improvement rate in the intervention group were higher. After treatment, Sedation-Agitation Scale (SAS) and Self-Rating Depression Scale (SDS) scores in the intervention group were decreased, compliance and self-care ability were improved, all of which were better than in the control group. Prognostic follow-up showed that the QoL in the intervention group was also higher than in the control group. Conclusions: The combined use of BVZ in XELOX-based chemotherapy can improve the clinical outcome and functional status of patients with CRC. In addition, MBSR intervention implemented during chemotherapy can effectively optimize patients' psychological state and treatment compliance, strengthen their self-care ability and improve their prognostic QoL.
