L'acide ascorbique dans le cancer du côlon: des applications fondamentales aux applications cliniques.

Compte tenu de l'innocuité et des avantages potentiels de l'administration intraveineuse d'acide ascorbique (AA) chez les patients cancéreux, il serait utile d'explorer plus avant ce concept thérapeutique. Dans cette revue, nous discutons des avantages potentiels de l'administration AA par voie intraveineuse sur le cancer colorectal et nous nous intéressons plus particulièrement à son effet sur la glycolyse dans les RAS de type sauvage et mutant. Nous effectuons une recherche MEDLINE sur PubMed et Ovid en utilisant l’acide ascorbique, la vitamine C par voie intraveineuse, la mutation KRAS, la mutation BRAF et le cancer colorectal (CRC) comme mots clés. Au niveau cellulaire, les cellules du cancer colorectal subissent un changement métabolique appelé effet Warburg pour permettre une plus grande absorption du glucose et l'utilisation de la glycolyse. Ce changement permet également à AA d'entrer, ce qui entraîne une perturbation de l'effet Warburg et un arrêt de la voie KRAS en aval dans les cellules cancéreuses du colon KRAS mutées. Au niveau clinique, les AA sont associés à la régression de la tumeur dans la maladie avancée et à une tolérance améliorée et aux effets secondaires du traitement standard. Sur la base de ces résultats, nous concluons que d’autres essais cliniques sont nécessaires à plus grande échelle pour examiner les avantages thérapeutiques des AA dans le cancer du côlon.
