The present invention provides novel uses and compositions for 5,10-methylene tetrahydrofolate ("5,10-CH2-THFA") in the treatment of cancer. The present invention is based on the surprising result that 5,10-CH2-THFA, while increasing the efficacy of 5-fluoruracil (5-FU) in reducing the rate of tumor growth and increasing survivorship, also reduces the toxicity to the patient of 5-FU. The present invention provides methods and compositions for treating cancer patients that include 5-FU, 5,10-CH2-THFA, and one or more additional anticancer drugs. Such methods and compositions can provide increased efficacy and reduced toxicity when compared with current treatment modalities.

La présente invention concerne de nouvelles utilisations et compositions faisant appel au 5,10-méthylène tétrahydrofolate ("5,10-CH2-THFA") pour le traitement du cancer. La présente invention est basée sur l'étonnante découverte selon laquelle le 5,10-CH2-THFA permet non seulement d'augmenter l'efficacité du 5-fluoruracil (5-FU) en termes de ralentissement de la croissance tumorale et d'augmentation de la survie, mais également de réduire la toxicité du 5-FU pour le patient. La présente invention concerne des méthodes et des compositions destinées à traiter des patients cancéreux et faisant appel au 5-FU, au 5,10-CH2-THFA ainsi qu'à un ou plusieurs médicaments anticancéreux additionnels. Ces méthodes et ces compositions permettent d'obtenir une efficacité accrue et une toxicité réduite par comparaison avec les modalités de traitement en cours.
