Clinical Trial Summary

Colorectal cancer is the third leading cause of cancer death and the fourth most commonly diagnosed cancer in the world. The importance of improving the quality of life of patients after colorectal cancer surgery has been gradually emphasized as the survival period after treatment increases. Especially, patients who underwent rectal cancer surgery experience complex bowel movement abnormalities called 'lower anterior resection syndrome' such as urgency, tenesmus, frequent stool passing, which severely degrades the quality of life after surgery. To manage these symptoms, several treatment modalities including medication, neurostimulation, or biofeedback have been tried, but they are not fully effective. Therefore, we designed this clinical trial to examine the effects of dietary supplementation of the fruit, 'Prune', on improving bowel function after anterior resection rectal cancer surgery. Prune is a dried fruit made from American plums with no seeds, and popular in the worldwide for its sweet and sour flavor and texture. In particular, the high content of sorbitol and dietary fiber softens the stool and improves the overall intestinal function, showing an excellent effect on alleviating constipation symptoms, which has been well studied in several clinical trials. This study is going to be performed on patients under the age of 65 with primary rectal cancer and rectosigmoid colon cancer who underwent low anterior resection (LAR) exclusive of neoadjuvant chemoradiotherapy. Patients who are treated preoperatively with metallic stent insertion will be excluded. Those who have fruit allergy, diabetes, or chronic constipation will also be excluded. Subjects will be randomly assigned to treatment (Prune) or control group (No-prune) immediately after the surgery. Subjects who are assigned to the treatment group consume a total of 100 g of prune per day and the subjects assigned to the control group are allowed to have a normal meal without prune for 18 days. All subjects should fulfill the LAR syndrome questionnaire, The European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-c30), and the defecation habit questionnaire on the day before the surgery and the postoperative day 21. And the subjects also fulfill the defecation diary till the postoperative day 21. The primary endpoint is the incidence of LAR syndrome. The secondary endpoint was the score of EORTC QLQ-C30, defecation habit questionnaire. Prune intake is less costly than conventional medical treatments for improving bowel function, and it is expected to show high compliance for patients due to the ease of application. Furthermore, if this study demonstrates that prune intake improves the symptoms of LAR syndrome and quality of life after rectal cancer surgery, the ingredients and components of prune could be used to develop new drugs for alleviating the symptoms of LAR syndrome.
