clove and Colorectal-Neoplasms

Jaboticaba is a Brazilian native berry described as a rich source of phenolic compounds (PC) with health promoting effects. PC from jaboticaba peel powder (JPP) have low intestinal bio-accessibility and are catabolized by gut microbiota. However, the biological implication of PC-derived metabolites produced during JPP digestion remains unclear. This study aimed to evaluate the antiproliferative effects of colonic fermented JPP (FJPP) in a 3D model of colorectal cancer (CRC) composed by HT29 spheroids. JPP samples fermented with human feces during 0, 2, 8, 24 or 48 h were incubated (10,000 µg mL

Colorectal adenocarcinoma are rare in Madagascar. Over a period of 8 years, such tumors were treated in the cancerology and surgery departments of Antananarivo. The low incidence and the relative young age at the time of diagnosis are comparable to observations made in other developing countries. Men represent 47 of the cases and women 34. On the average, patients were 52.3 years old (range: 23-78 years). The most frequent early symptoms are rectorrhagia (26 cases) for rectal cancer, abdominal pain (9 cases) and transit bowel disorders (9 cases) for colon cancer. Between the first symptom and diagnosis, the average delay is 8.5 months (range: 2 days-37 months). No risk factor was found. Thirteen patients did not receive any treatment, 8 were only submitted to radiotherapy and 60 were surgically treated with a curative intent in 26 cases, a palliative one in 32 cases and for diagnosis in 2 cases. Among the 63 tumors available for modified Dukes' classification of Astler-Coller, 9.5% are stage B1, 23.8% are stage B2, 11% are stage C1, 15.9% are stage C2 and 39.7% are stage D; there are no stage A. There is no epidemiological particularity for these cancers in Madagascar. The poor prognosis is probably mainly related to a lack of appropriate medical and surgical facilities.
