BACKGROUND/AIMS: MSC (trade-name AVEMAR) is a per os applicable complex of multiple, biologically active molecules obtained from fermented wheat-germ extract. Preclinical studies suggest potent anti-metastatic activity and it has a favorable toxicity profile. It has been aimed in a pilot-scale, phase II clinical study to document whether or not MSC as a support to surgery or plus chemotherapy adds any therapeutic benefit compared to the same combination without MSC in colorectal cancer. METHODOLOGY: From 1998 to June 1999, 18 control patients and 12 consecutive colorectal cancer patients respectively, were enrolled into this study. All patients underwent curative surgery. The control group (18 patients) received no other therapy or adjuvant chemotherapy alone. The MSC group (12 patients) received MSC alone or plus adjuvant chemotherapy. Until now, the median follow-up has been 9 months. RESULTS: Interim data of the study document that in the MSC group no new metastases, neither hepatic nor other, have occurred, so far. On the contrary, several new metastases have developed in the control group. CONCLUSIONS: Orally administered MSC is a potent candidate to be regarded as a supportive therapy to surgery or plus chemotherapy for colorectal cancer patients.

A medical nutriment has supportive value in the treatment of colorectal cancer
MSC (Avemar) is a medical nutriment of which preclinical and observational clinical studies suggested an antimetastatic activity with no toxicity. This open-label cohort trial has compared anticancer treatments plus MSC (9 g once daily) vs anticancer treatments alone in colorectal patients, enrolled from three oncosurgical centres; cohort allocation was on the basis of patients' choice. Sixty-six colorectal cancer patients received MSC supplement for more than 6 months and 104 patients served as controls (anticancer therapies alone): no statistical difference was noted in the time from diagnosis to the last visit between the two groups. End-point analysis revealed that progression-related events were significantly less frequent in the MSC group (new recurrences: 3.0 vs 17.3%, P<0.01; new metastases: 7.6 vs 23.1%, P<0.01; deaths: 12.1 vs 31.7%, P<0.01). Survival analysis showed significant improvements in the MSC group regarding progression-free (P=0.0184) and overall survivals (P=0.0278) probabilities. Survival predictors in Cox's proportional hazards were UICC stage and MSC treatment. Continuous supplementation of anticancer therapies with MSC for more than 6 months is beneficial to patients with colorectal cancer in terms of overall and progression-free survival.
