Evaluation of Quality of Life among Patients with Various Types of Cancer Treated with Oral Lentinula Edodes Mycelia Extract

Abstract

Extract of Lentinula edodes mycelia (LEM) reportedly maintains and improves the quality of life (QOL) of patients with cancer who undergo chemotherapy. We investigated the influence of LEM extract on the QOL of 73 Japanese patients with different backgrounds and stages of cancer who were undergoing various types of therapy at 16 institutions. All patients were orally administered with LEM (1200 mg/day) for four weeks. We compared changes in their QOL before and after taking LEM using the EORTC-QLQ-C30. The QOL scores for emotional function and fatigue were significantly improved after LEM intake. Global QOL and physical function scores improved only in patients with cancer at stages III and IV. These findings suggest that oral LEM intake improves the QOL of patients with advanced cancer.
