Filter by:The aim of this observational study is to retrospectively collect current survival data for 3995 primary rectal cancer patients who were extracted from 5097 rectal cancer patients admitted in Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2010. Moreover, based on a Cox model, we want to develope a nomogram that predicts local recurrence, distant metastases, and survival for patients with rectal cancer treated with pre- or postoperative chemoradiotherapy (CRT).
TME (Total mesorectum excision) is the golden standard of radical resection for mid-low rectal cancer. However, the damage of pelvic autonomic nerve following with TME principle will lead to high incidence of urinary and sexual function disorder. PANP (pelvic autonomic nerve preservation) surgery played a role in decreasing incidence of urinary and sexual function disorder. However, 32%-44% patients still suffered from urinary and sexual function disorder when underwent open (O-PANP-TME) or laparoscopic PANP TME surgery (L-PANP-TME). In the early stage of work, the investigators performed preservation of Denovilliers' fascia in L-PANP-TME to discuss the protection of urinary and sexual function of male mid-low rectal cancer patients. The results showed that preservation of Denovilliers' fascia in L-PANP-TME significantly decreased incidence of urinary and sexual function disorder. In order to further confirm the early work, the investigators design a randomized controlled clinical trial to compare differences in urinary and sexual function protection and long-term outcomes between preservation and excision of Denovilliers' fascia in L-PANP-TME.
Indications for colostomy are rectal or anal cancer, diverticular disease, radiation enteritis, complex perirectal fistulas, anorectal trauma, severe incontinence, motility and functional disorders. It is frequently required in critically ill patients who may not be able to tolerate a laparotomy. Laparoscopic-assisted colostomy is an alternative method for colostomy without laparotomy, but require general anesthesia. Additionally, percutaneous anterior colopexy under colonocopic control offers the possibility for improved and faster fixation of the anterior colonic wall to the anterior abdominal wall. The objective of this study is to evaluate the feasibility of performing fecal diversion with the help of a colonoscope and colopexy, without the additional morbidity of abdominal exploration.
The investigators start this prospective study to evaluate the efficacy of laparoscopic total mesorectal excision after concurrent chemo-radiation therapy with hyperthermia in locally advanced rectal cancer.
Although neoadjuvant radiotherapy greatly decreases local recurrence in locally advanced rectal cancer patients undergoing surgery, it inevitably results in short-term and long-term toxicities. More importantly, it has not been confirmed that neoadjuvant radiotherapy could improve overall survival. The purpose of this study is to compare the effects of chemotherapy alone using a combination regimen known as XELOX (capecitabine and oxaliplatin ) and selective use of the standard treatment to the standard treatment of chemotherapy and radiation.
This phase II trial studies how well regorafenib works in reducing the return of disease in patients with rectal cancer that has not spread to another place in the body who have completed curative-intent treatment. Regorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Regorafenib may also help keep cancer from coming back after it has disappeared following the initial therapy.
To evaluate the efficacy and safety of SOX or mFOLFOX6 as neoadjuvant chemotherapy in patients with resectable rectal cancer, and to identify the more promising regimen.
Anastomotic leak after low rectal cancer surgery occurs between 3 and 24% of the cases and is a severe complication leading to sepsis, permanent colostomy, higher risk of local cancer recurrence and eventually death. In order to prevent this complication a protecting diverting stoma is usually fashioned with consequent morbidity due to the stoma and its closure and severe impact on patients' quality of life. This prospective, multi-center, parallel-arm, randomized controlled equivalence trial is aimed to demonstrate whether a transanal reinforcement of the suture line can prevent anastomotic leakage after low rectal cancer surgery thus avoiding the need for a covering ileostomy
The primary objective is to describe the functional outcome of patients that choose for organ saving treatment.
The purpose of this study is to determine the maximum tolerated dose and safety of S-1 plus radiotherapy for patients with rectal cancer
