A Message to Members of ACG, AGA and ASGE Regarding a Statement from the Multisociety Task Force on Colorectal Cancer

The US Multi-Society Task Force (MSTF) on Colorectal Cancer represents theAmerican College of Gastroenterology, the American Gastroenterological Association and The American Society for Gastrointestinal Endoscopy. The MSTF issues recommendations on prevention of colorectal cancer and issued screening recommendations for colorectal cancer in 2017.

The MSTF has previously recommended that colorectal cancer screening for averagerisk persons (persons who do not have a family history of colorectal cancer in a firstdegree relative) begin at age 45 years in African Americans and age 50 in other groups. The MSTF has reviewed the recent recommendation from the American Cancer Society (ACS) to lower the age to begin screening from 50 to 45 years in all Americans. This change was a qualified recommendation based largely on a modeling study utilizing updated data on the incidence of colorectal cancer in younger people.

Evidence from screening stUdies to support lowering the screening age is very limited at this time. Based on the modeling study used to support the ACS recommendation, the MSTF recognizes that lowering the screening age to 45 may improve earlydetection and prevention of CRC. The MSTF expects the new ACS recommendation to stimulate investigation that will clarify the benefits and risks of earlier screening.

As the MSTF has previously noted and discussed, rates of colorectal cancer are increasing in Americans down to age 20 years. Beginning screening at 45 years addresses only part of the increasing risk of colorectal cancer in young persons. For all persons under 50 years, it remains critical to promptly assess symptoms consistent with colorectal cancer. In particular, rectal bleeding and unexplained iron deficiency anemia have substantial predictive value for colorectal cancer and should be thoroughly evaluated.

Certain diets increase risk for colorectal cancer

Inflammation-causing diets, or those high in meats, refined grains and high-calorie beverages, appeared associated with a higher risk for developing colorectal cancer, according to results published in JAMA Oncology.

The association appeared higher among overweight or obese men, lean women, and men and women who did not consume alcohol.

Inflammation is associated with cancer development, including colorectal cancer.

"Intervention studies have shown that diet modulates inflammation; therefore, dietary patterns with higher inflammatory potential may influence colorectal cancer risk," Fred K. Tabung, MSPH, PhD, research associate in the department of nutrition at Harvard T.H. Chan School of Public Health, and colleagues wrote. "There are likely complex added effects and interactions of multiple foods and nutrients in diet."

Fecal Transplant Cost Effective for Recurrent C Difficile

Jim Kling October 25, 2013 SAN DIEGO

A new analysis of the cost effectiveness of various strategies to combat recurring Clostridium difficile infections (CDIs) shows that fecal microbial transplantation delivered by colonoscopy is the best approach.

"Fecal transplant has emerged as a new and effective therapy for CDI, but we know there are costs associated with it," Gauree Gupta Konijeti, MD, a fellow at Massachusetts General Hospital in Boston, told Medscape Medical News. "We wanted to see whether it makes sense on a cost-effectiveness scale." Dr. Konijeti presented the results here at the American College of Gastroenterology 2013 Annual Scientific meeting. There are now several options available to treat the condition, but they have not been evaluated for cost effectiveness when both the initial treatment cost and the health benefits of preventing recurrence have been taken into account. Dr. Konijeti and her team used a decision-analytic model to compare the cost effectiveness of 4 treatment strategies for a first episode of CDI: fecal transplantation, metronidazole, vancomycin, and fidaxomicin. The team tested up to 2 recurrences after the initial episode.

Fecal transplantation delivered by colonoscopy had an incremental cost-effectiveness ratio of $46,419, compared with vancomycin. It also easily outperformed fidaxomicin and metronidazole because of the higher costs and lower efficacy of these drugs. Fecal transplantation remained the most cost-effective approach, with cure rates higher than 96.4%, a CDI recurrence rate below 6.9%, and a cost of less than $1223. The researchers also constructed a model of fecal transplantation that was delivered by enema or nasoduodenal infusion, but found that colonoscopy was more cost effective because it's efficacy is better than the other 2 delivery systems.

Transplantation by Enema or Nasoduodenal Infusion Dr. Konijeti expressed optimism that fecal transplantation delivered by enema or nasoduodenal infusion could, with improvements, match the efficacy of colonoscopy-delivered transplants. "We typically use lower fecal microbiota doses for nasoduodenal and enema delivery, which might be one of the reasons they don't have similar efficacy," she said. If comparable efficacy could be achieved, these delivery systems would be preferable because they cost less than colonoscopy. In clinical settings where colonoscopy was not available, the researchers found that vancomycin was the most cost-effective option.

The cost of fidaxomicin, at $462,706 per quality-adjusted life year, is prohibitive compared with the older drug. "It's a timely study because recurrent C difficile is truly recurrent; a lot of patients have multiple episodes over a period of time," session moderator Jonathan Leighton, MD, from Mayo Clinic Arizona in Scottsdale, told Medscape Medical News. "I think the primary reason that fecal transplant was shown to be the most cost-effective strategy is that, at least in studies to date, fecal transplant has the highest cure rates. You don't have multiple recurrences if you treat them that way." Dr. Konijeti and Dr. Leighton have disclosed no relevant financial relationships.
