[Sequential methotrexate and fluorouracil in metastasizing colorectal carcinomas. Results of a phase II pilot study (author's transl)].

A sequential combination of methotrexate and 5-fluorouracil was used for treatment of 20 patients with metastasizing colorectal carcinomas. Pretreatment with 5-fluorouracil had been given to five patients. While the chemotherapeutically pretreated patients showed two partial remissions, two minimal remissions and one progression, the remaining patients showed one full remission, six partial remissions, five minimal remissions and three progressions. The average partial remission time of these patients was 7,9 months. The average survival time will probably be more than one year. The toxicity of treatment was slight.
