Lithium carbonate ameliorates neutropenia associated with cancer chemotherapy. The effect of lithium on platelet suppression has not, however, been well established. In the present study, five patients with ovarian carcinoma received daily lithium during alternate cycles of treatment with hexamethylmelamine, cyclophosphamide, adriamycin, and cis‐platinum. Analysis of myelosuppression was performed on 24 paired consecutive cycles given at identical doses, one with and one without lithium. During lithium cycles, nadir leukocyte, neutrophil, and platelet counts were significantly higher (P<0.01, <0.01, <0.05 respectively) and the interval between treatments was shorter (P<0.01). One patient who has received 11 cycles of chemotherapy continues to receive 100% doses owing to the beneficial effect of lithium on chemotherapy‐induced thrombocytopenia. Lithium was poorly tolerated by some patients because of either tremor or nausea and vomiting, in spite of nontoxic serum lithium levels. The amelioration of drug‐induced platelet suppression as well as neutrophil suppression noted in this study suggests that lithium's effect on hematopoiesis is not limited to stimulation of neutrophil production. The ability of lithium to decrease chemotherapyinduced myelosuppression suggests that lithium administration may facilitate escalation of chemotherapy doses in selected patients.
