Abdominal Massage After Colon Surgery for Cancer

Postoperative ileus is a transient gastrointestinal dysmotility following abdominal surgery that leads to bloating, abdominal distention, visceral pain, nausea, vomiting, and delayed passage of flatus and stool. This paralytic state lasts longer when surgery involves the distal rather than the proximal digestive tract. Its incidence following colorectal surgery is between 10% and 30%. The main factors of postoperative ileus include age, predisposed constipation, method of anesthesia, type of surgical approach, perioperative analgesia, inflammatory reactions, and the psychopathology of the patient. Enhanced recovery after surgery (ERAS) provides patients with optimal means to counteract or minimize the deleterious effects of surgery, in particular toward minimizing postoperative ileus. Expert consensus among surgeons, anesthesiologists, physiotherapists, dieticians, and other team members has been reached that stated 24 clinical statements concerning preoperative, peroperative and postoperative periods that should be included in current rehabilitation programs in colorectal surgery. In China, massage, a 3000-year-old therapy guided by the theory of Yin and Yang, is widely used to treat various diseases. Chapelle and Bowe showed that abdominal massage reduced experimental postoperative ileus in a rat model and suggested that the effect was due to the attenuation of inflammation. Abdominal massage has not widely been applied after colorectal surgery. Due to the scarcity of literature on abdominal massage, it has never been considered to be part of ERAS recommendations in colorectal surgery. Nevertheless, massage involving profound maneuvering of the viscera through abdominal palpation and breathing has been used as part of the local postoperative protocol in our department for many years with interesting results, and no complication has been reported. To our knowledge, only one study has explored the effect of mechanical abdominal massage on the duration of ileus after colectomy. The aim of this prospective, multicenter randomized controlled trial (RCT) is to compare return of intestinal transit using the GI-2 criteria as defined by the time to first defecation and time to tolerance of solid food following the operation in two groups of patients following an ERAS protocol for colonic cancer surgery, one with and the other without early postoperative abdominal massage.

A Phase I, Open-Label, Multi-center Study to Assess the Safety, Tolerability and Pharmacokinetics of AZD6244 (ARRY-142886)

This study is being conducted to determine if a combination of AZD6244 given orally twice a day with standard doses of selected chemotherapies will be safe and tolerable for cancer patients with advanced solid tumors. The highest tolerated dose of AZD6244 in combination with selected chemotherapies will be evaluated. The study will also investigate how AZD6244 in combination with standard chemotherapies are absorbed, distributed and excreted by the body as well as the length of time that the drugs remain in the body. Initial and periodic assessments will establish patient response to the combination therapies

ctDNA-guided Surveillance for Stage III CRC, a Randomized Intervention Trial

IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.

Chinese Colorectal Cancer Database

1. To establish the Chinese people's own clinical data database of colorectal cancer, reflecting the law and characteristics of colorectal cancer patients in China. 2. Based on colorectal cancer surgery, collect clinical data, especially data on clinical manifestations, complications, laboratory tests, auxiliary examinations, postoperative clinical effects, surgical complications, and colorectal cancer recurrence, so as to lead the direction of clinical practice and academic research of colorectal cancer surgery in China. It provides a certain basis for future research on colorectal cancer. 3. Provide academic consultation and data support to national health authorities.
