Common Gastro Disease Occurs Even With High-Fiber Diet - Drugs.com MedNews

FRIDAY Jan. 27, 2012 -- Eating a high-fiber diet does not lower a person's risk of diverticulosis, but a low-fiber diet might, according to a new study that contradicts what doctors have believed for decades....

Mucinous Tumors of the Ovary: Diagnostic Challenges at Frozen Section and Clinical Implications

Conclusions

Our study showed a 34% rate of discordance between FS and final diagnosis. Given that 5 cases (7%) were of GI origin, intraoperative assessment of the appendix should be performed in all mucinous ovarian tumors.

Highlights

► We examined 73 consecutive cases of mucinous ovarian tumors that had frozen section (FS) at the time of surgery.
► The rate of discordance between FS and final diagnosis was 34%.
► Consideration of appendiceal tumors is important as 7% of all cancers were found to be gastrointestinal in origin.

abstract: Clinical predictors of (Avastin) bevacizumab-associated gastrointestinal perforation

Abstract

OBJECTIVES: Bevacizumab is a generally well-tolerated drug, but bevacizumab-associated gastrointestinal perforations (BAP) occur in 0 to 15% of patients with ovarian carcinoma. Our goal was to evaluate the clinical predictors of BAP in order to identify factors, which may preclude patients from receiving treatment.
METHODS: We conducted a review of patients with recurrent epithelial ovarian carcinoma treated with bevacizumab between 2006 and 2009. Demographic and treatment data were collected for statistical analysis.
RESULTS: Eighty-two patients were identified; perforation occurred in 8 (9.76%). Among patients with perforation, a significantly higher incidence of prior bowel surgeries (p=0.0008) and prior bowel obstruction or ileus.
CONCLUSIONS: Predicting BAP remains a challenge. Bowel obstruction or ileus appears to be associated with increased risk of BAP.

The Gastrointestinal Phenotype of Germline Biallelic Mismatch Repair Gene Mutations (Lynch Syndrome)

Abstract
OBJECTIVES:A novel cancer syndrome associated with biallelic mismatch repair (MMR) mutations has been described recently. Patients presenting with childhood-onset gastrointestinal (GI) cancers may carry biallelic MMR mutations and have a distinct phenotype from classic Lynch syndrome. The aim of this study was to characterize patients with GI small bowel and/or colorectal cancers (CRCs) who have germline biallelic MMR mutations.
METHODS:A search of a Canadian GI cancer registry and literature review to identify patients with biallelic MMR was conducted.
RESULTS:The database identified 237 patients with intestinal cancer diagnosed before the age of 35 years. Five (2.1%) patients had biallelic MMR mutations. Overall, 32 individuals, from 29 families, with biallelic MMR gene mutations and GI cancers were identified by the registry and literature review. Among the 29 patients with CRCs, the mean age of first cancer diagnosis was 16.4 years (range: 5-28).
