| Summary: | This study examined the changes in physical function and quality of life (QOL) of postoperative patients with pancreatic cancer for 3 months after surgery and examined the factors affecting the QOL at the 3 months after surgery. Methods: This study comprised 32 pancreatic cancer patients who underwent surgery at our hospital. Among these patients, 20 patients for whom data was measured before surgery to 3 months after surgery were selected for statistical analyses: 8 males and 12 females, 69.8 ± 7.4 years. The preoperative and postoperative rehabilitation was given to patients under the guidance of a physiotherapist. Nutritional status, body composition, physical function, gait assessments, and QOL were investigated. Results: Body weight, body fat mass, body fat percentage, body mass index (BMI), and muscle mass significantly decreased 3 months after surgery compared with their respective preoperative values. The mean grip strength at the time of 3 months after the surgery had decreased significantly from 27.3 kg to 24.5 kg. The mean skeletal muscle mass index (SMI) had decreased significantly from 6.3 kg before surgery to 5.9 kg after the surgery. The QOL scores for global health status, physical, and role showed significant decreases 2 weeks after surgery compared with the respective preoperative scores. Significant improvements in these scores were observed 3 months after surgery compared with the respective scores 2 weeks after surgery. Physical function assessments after surgery were associated with QOL 3 months after surgery. Conclusion: Recovery of patients after pancreatic cancer surgery in body weight, BMI, body fat percentage, body fat percentage, muscle mass, SMI, and grip strength was not sufficient at the time of 3 months after surgery. It has been observed that physical function of patients has affected the improvement of QOL.
