title: Methyl-CCNU versus methyl-CCNU and 5-fluorouracil in carcinoma of the large bowel.
abstract: 5-Flourouracil (5-FU) and methyl-CCNU have demonstrated separate sensitivities in carcinoma of the large bowel. This study was an attempt to see if methyl-CCNU versus methyl-CCNU plus 5-FU would demonstrate different responses in advanced colorectal carcinoma. Forty-nine patients have been evaluated, 14 receiving methyl-CCNU and 35 receiving 5-FU plus methyl-CCNU. One partial response has been seen with methyl-CCNU alone in a patient with liver metastasis. Thirteen partial responses have been noted in patients treated with the two-drug combination. There was a significant difference in the median survival of the responders versus the nonresponders for the two-drug group. Side effects were expected: nausea and vomiting, leukopenia, and thrombocytopenia. Plasma carcinoembryonic antigen and urine arylsulfatase were measured in all patients and correlated well with response.
