Curcumin Combined with FOLFOX Chemotherapy Is Safe and Tolerable in Patients with Metastatic Colorectal Cancer in a Randomized Phase IIa Trial.

Background: Curcumin is the main active ingredient of the spice turmeric, investigated extensively for putative anticancer properties.

Objectives: This phase IIa open-labelled randomized controlled trial aimed to assess safety, efficacy, quality of life, neurotoxicity, curcuminoids, and C-X-C-motif chemokine ligand 1 (CXCL1) in patients receiving folinic acid/5-fluorouracil/oxaliplatin chemotherapy (FOLFOX) compared with FOLFOX + 2 g oral curcumin/d (CUFOX).

Methods: Twenty-eight patients aged >18 y with a histological diagnosis of metastatic colorectal cancer were randomly assigned (1:2) to receive either FOLFOX or CUFOX.

An Abstract Provides "seAFOod" for Thought.

A recent article published in reports on the seAFOod trial, in which patients with colorectal adenomas received aspirin and/or eicosapentaenoic acid (EPA, an omega-3 polyunsaturated fatty acid) post-resection. The article's abstract indicates that the primary trial endpoint, adenoma detection rate, is negative, but it does not give any indication of the remarkable secondary endpoint (adenoma number) results, which strongly suggest chemopreventive efficacy of both agents. Given the difficulty researchers and physician-scientists experience in staying abreast of the latest literature in the field, inclusion of secondary findings in abstracts should be strongly considered.

Effects of a Grapevine Shoot Extract Containing Resveratrol and Resveratrol Oligomers on Intestinal Adenoma Development in Mice: In Vitro and In Vivo Studies.

Scope: Evidence suggests that the dietary consumption of plant extracts containing polyphenols might help prevent the onset of cancers of the gastrointestinal tract. In the present study, the chemopreventive and antiproliferative efficacy of a grapevine shoot extract (Vineatrol®30) containing resveratrol and resveratrol oligomers is investigated in vivo and in vitro.

Methods And Results: The in vivo study is performed using Apc mice on a high-fat diet, which represents a model of human adenomatous polyposis, while the potential of the extract as well as some of its isolated constituents to inhibit intestinal adenoma cell proliferation in vitro is investigated using APC10.

Response to comment on "Cancer chemoprevention: Evidence of a nonlinear dose response for the protective effects of resveratrol in humans and mice".

Low-dose resveratrol did not have the opposite effect on intestinal adenoma development when given in a standard diet instead of a high-fat diet, although we agree on the need for more information on the interaction of diet-derived compounds such as resveratrol and other lifestyle, metabolic and hormonal factors.

Targeting cancer stem-like cells using dietary-derived agents - Where are we now?

Diet has been linked to an overwhelming proportion of cancers. Current chemotherapy and targeted therapies are limited by toxicity and the development of resistance against these treatments results in cancer recurrence or progression. In vitro evidence indicates that a number of dietary-derived agents have activity against a highly tumorigenic, chemoradiotherapy resistant population of cells within a tumour.
