Acizii grasi Omega-3 reprezinta agenti potentiali de prevenire pentru cancerul de colon recurent.

Exista din ce in ce mai multe probe care sustin procesele tumorale, inclusiv cele colorectale sporadice, sun conduse de catre celulele stem care se reinnoiesc singure si nu numai atat, dar sunt rezistente la agentii chimioterapici. Aceste lucruri obliga la imbunatatirea strategiilor preventive si terapeutice in caz de cancer de colon.
Acizii grasi polinesaturati Omega 3 
Increasing evidence supports the contention that many malignancies, including sporadic colorectal cancer, are driven by the self-renewing, chemotherapy-resistant cancer stem/stem-like cells (CSC/CSLC), underscoring the need for improved preventive and therapeutic strategies targeting CSCs/CSLCs. 
Omega-3 polyunsaturated fatty acids (ω-3 PUFA), have been reported to inhibit the growth of primary tumors, but their potential as a preventive agent for recurring cancers is unexplored. 
The primary objectives of this investigation are (i) to examine whether eicosapentaenoic acid (EPA; one of the ω-3 PUFA) synergizes with FuOx (5-FU+Oxaliplatin), the backbone of colon cancer chemotherapy, and (ii) whether EPA by itself or in combination with conventional chemotherapy prevents the recurrence of colon cancer via eliminating/suppressing CSCs/CSLCs. FuOx-resistant (chemoresistant; CR) colon cancer cells, highly enriched in CSCs, were used for this study. 
Although EPA alone was effective, combination of EPA and FuOx was more potent in (i) inhibiting cell growth, colonosphere formation, and sphere-forming frequency, (ii) increasing sphere disintegration, (iii) suppressing the growth of SCID mice xenografts of CR colon cancer cells, and (iv) decreasing proinflammatory metabolites in mice. In addition, EPA + FuOx caused a reduction in CSC/CSLC population. 
The growth reduction by this regimen is the result of increased apoptosis as evidenced by PARP cleavage. Furthermore, increased pPTEN, decreased pAkt, normalization of β-catenin expression, localization, and transcriptional activity by EPA suggests a role for the PTEN-Akt axis and Wnt signaling in regulating this process. Our data suggest that EPA by itself or in combination with FuOx could be an effective preventive strategy for recurring colorectal cancer.

A fost proiectata ideea ca ridicarea pe tot parcursul anului a nivelurilor serice minime de vitamina D, de la 20 ng/ml pana la 40-60 ng/ml ar putea preveni aparitia a aproximativ 58000 de cazuri noi de cancer de san si a 49000 de cazuri noi de cancer colorectal in fiecare an.
