A few reports have documented overdoses of vincristine sulfate. The present report describes our experience with serious complications of a vincristine overdose in an 18-year-old female who had methotrexate-resistant invasive mole. The patient received VAC therapy as the second line chemotherapy after 2 courses of MTX therapy. In the 6th course of VAC therapy, she was given 5 consecutive daily doses of VCR by mistake. On the 5th day of this VAC therapy, she showed the following toxic symptoms: abdominal pain, lumbago, insomnia, bleeding tendency, absence of motor reflex, leukopenia, and paralytic ileus. These symptoms led to realization of the VCR overdose. Leucovorin calcium administration and supportive treatment were carried out. Although it was difficult to evaluate the efficacy of leucovorin calcium on the vincristine toxic symptoms, she recovered and was discharged on the 36th hospital day.

Vincristine, referred to as a vinka alkaloid, has been used as a component of the various chemotherapeutic regimens. The major side effects of the usual dosage of vincristine are bone marrow suppression, gastrointestinal disorder, and neurotoxicity. A 53-year-old cervical cancer patient received 14 mg (4 mg/m2/day for 2 days) of vincristine instead of vinblastine because of the similarity between the two names. Then life threatening toxicities including paresthesias, bone marrow depression, severe oral mucositis, paralytic ileus, bladder atony, myalgia, muscle weakness, high fever, derangements of various organs (liver, heart), hypertension, and insomnia were encountered. But hypotension and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) were not observed. Other than paresthesias in the extremities, the patient recovered completely from toxic impairments with intensive symptomatic and supportive care. In order to prevent the administration of the overdosed drug, it would be advisable for chemotherapy to be administered only by an experienced physician who is able to check the dose and concentration.
