Response to 5-fluorouracil chemotherapy is modified by dietary folic acid deficiency in Apc(Min/+) mice.

5-Fluorouracil (5-FU) has been the foundation of advanced colorectal cancer treatment for over 40 years. The Apc(Min/+) mouse, which is genetically predisposed to intestinal neoplasia, was used to examine the effects of 5-FU in this system and the impact of dietary folic acid on those effects. 5-FU treatment resulted in a 60-80% reduction in tumor number. Clinically relevant toxicities, including myelosuppression and mucositis, are a part of this response. Tumor numbers rebounded completely following termination of 5-FU therapy, indicating that the drug inhibits tumor growth but does not eradicate them. In mice that were fed with a defined diet containing no folic acid (0 ppm), 5-FU not only induced regression of pre-existing tumors, but also inhibited tumor recovery following drug withdrawal. Our data indicate that a dietary folic acid deficiency, in promoting tumor regression and inhibiting tumor recovery, may enhance the therapeutic effects of 5-FU.

Intracranial calcification mimicking the Sturge-Weber syndrome: a consequence of cerebral folic acid deficiency?

Cerebral cortical calcification identical to that of the Sturge-Weber syndrome was observed in two children. In one child the calcification appeared after intrathecal administration of methotrexate and skull irradiation because of leukemia involving the central nervous system. In the other child, who had coeliac disease and epilepsy, the calcification appeared after treatment with anticonvulsants. This treatment was also contributing to the development of profound megaloblastic anemia. The unspecificity of the Sturge-Weber calcification is stressed and the hypothesis is put forward that the calcification may be secondary to folic acid deficiency interfering with the matabolism in the central nervous system.
