Popis: 9026^ Background: Malnutrition reduces tolerance to treatment and survival in numerous cancers, including metastatic colorectal cancer (mCRC). Previous studies have shown that chemotherapy toxicity may be linked to sarcopenia. We evaluated the effect of sarcopenia on chemotherapy toxicity among mCRC patients. Methods: In this prospective, cross-sectional, multicenter study, oncological and nutritional data were collected in all consecutive mCRC patients between March 7th and March 20th 2005 in three hospitals. Computed tomography (CT) images were analysed using Slice-O-Matic software V4.3 (Tomovision) to evaluate cross-sectional areas (cm2) of muscle tissue (MT), visceral and subcutaneous adipose tissue (VAT and SAT). The 3rd lumbar vertebra (L3) was chosen as a reference, since L3 and whole-body measurements are linearly related. Indexed on height, MT, VAT and SAT (cm2/m2), were computed and described, after stratification on sex. In accord with the literature, sarcopenia was defined as MT 25kg/m²). These results are to be compared to the 38% (F) and 82% (M) of patients with sarcopenia. Grade 3-4 toxicities were observed in 28% of the cases, with neurotoxicity in 6%, diarrhea 2%, anemia 2%, neutropenia 9%, and nausea and vomiting 6%. In multivariate analysis including age, sex, BMI, sarcopenia, SAT and VAT, the only factor associated with grade 3-4 toxicity was sarcopenia (OR= 13.55 95% CI [1.08;169.31], p=0.043). Conclusions: In mCRC patients undergoing chemotherapy, low muscle tissue was much more frequently observed (68%) than “visible” malnutrition (4%). Despite the small number of patients included in our study, we showed that sarcopenia was associated with severe chemotherapy toxicity in mCRC.
