Mitomycin

Mitomycin for Injection is not recommended as single-agent, primary therapy. It has been shown to be useful in the therapy of disseminated adenocarcinoma of the stomach or pancreas in proven combinations with other approved chemotherapeutic agents and as palliative treatment when other modalities have failed. Mitomycin for Injection is not recommended to replace appropriate surgery and/or radiotherapy.

Mitomycin is contraindicated in patients who have demonstrated a hypersensitive or idiosyncratic reaction to it in the past. Mitomycin is contraindicated in patients with thrombocytopenia, coagulation disorder, or an increase in bleeding tendency due to other causes.

Patients being treated with mitomycin must be observed carefully and frequently during and after therapy. The use of mitomycin results in a high incidence of bone marrow suppression, particularly thrombocytopenia and leukopenia. Therefore, the following studies should be obtained repeatedly during therapy and for at least eight weeks following therapy: platelet count, white blood cell count, differential, and hemoglobin.

The occurrence of a platelet count below 100,000/mm 3 or a WBC below 4,000/mm 3 or a progressive decline in either is an indication to withhold further therapy until blood counts have recovered above these levels. Patients should be advised of the potential toxicity of this drug, particularly bone marrow suppression. Deaths have been reported due to septicemia as a result of leukopenia due to the drug. Patients receiving mitomycin should be observed for evidence of renal toxicity.

Mitomycin should not be given to patients with a serum creatinine greater than 1.7 mg percent. Usage in Pregnancy Safe use of mitomycin in pregnant women has not been established. Teratological changes have been noted in animal studies. The effect of mitomycin on fertility is unknown.
