Tastes associated with parenteral chemotherapy for breast cancer.

Abstract: We employed a structured interview to retrospectively study tastes and vomiting associated with the parenteral components of cyclophosphamide, methotrexate, and 5-FU in 45 patients with stage II-IV breast cancer. Sixteen patients (36%) reported tastes which generally occurred in each cycle within 30 minutes of parenteral drug administration, lasted less than or equal to 1 hour, and were bitter. Five patients recalled that tastes seemed to produce vomiting. Tasting was significantly associated with postchemotherapy (P less than 0.01) but not anticipatory vomiting. Employing logistic regression techniques, tasting did not significantly improve prediction of anticipatory vomiting by postchemotherapy vomiting. Tastes may be produced by the action of plasma or salivary cyclophosphamide, methotrexate, and 5-FU on taste buds. While tastes might cause some vomiting, they are not necessary for it. Because this was a retrospective study with a small sample, these findings require confirmation.

Phase I study of N-methylformamide in patients with advanced cancer.

Abstract: N-Methylformamide (N-MF) belongs to a class of polar-planar compounds which induce cellular differentiation. Preclinical antitumor activity was demonstrated against human mammary, colon, and lung tumor xenografts and L1210 and P388 murine leukemias. This phase I study used a single bolus infusion of N-MF given weekly X 3 doses every 6 weeks. Thirty-five patients were treated with N-MF at doses which ranged from 125 to 3125 mg/m2/week. The dose-limiting toxic effects included nausea and vomiting, anorexia, malaise, and liver function abnormalities. No myelosuppression was seen. The recommended dose for phase II trials of N-MF with this schedule is to initiate therapy at 2000 mg/m2 weekly X 3 and escalate to 2500 mg/m2 if the initial dose was well tolerated.
