文摘

After esophagectomy, esophageal cancer patients suffer from malnutrition, anorexia, and dysfunction of digestion and absorption. Rikkunshito, a traditional Japanese herbal medicine, reportedly attenuates gastrointestinal symptoms and appetite loss after gastrointestinal surgery. We evaluated the clinical effect of rikkunshito and its relationship with ghrelin in esophageal cancer patients after esophagectomy.

Methods

This prospective nonrandomized study included 40 patients with esophageal cancer who underwent esophagectomy at Wakayama Medical University Hospital. They were assigned to either the control group (n = 20, April 2011-January 2012) or the rikkunshito group (n = 20, January 2012-August 2012). Patients in the rikkunshito group received 2.5 g of rikkunshito before every meal for 48 wk beginning 4 wk after surgery. During the 48-week treatment, we assessed body weight loss, nutritional parameters, and quality of life (Functional Assessment of Cancer Therapy-Esophageal scale). The primary end point was the rate of body weight loss in two groups after the 48-week treatments.

Results

The rate of body weight loss was significantly less in the rikkunshito group than in the control group (P = 0.016). The acyl ghrelin level after the 48-week treatments was significantly higher in the rikkunshito group (131.7% ± 74.5%) than in the control group (75.6% ± 47.5%, P = 0.039). For the Functional Assessment of Cancer Therapy-Esophageal symptom scale, satisfaction of food consumption in the rikkunshito group was significantly better than in the control group at 52 wk postoperatively (P = 0.031).

Conclusions

For esophageal cancer patients after esophagectomy, rikkunshito is useful for improving body weight loss in connection with an increase in plasma acyl ghrelin levels.
