Mitomycin is an antineoplastic antibiotic which is enzymatically reduced to its active metabolite within susceptible cells. The active metabolite appears to cause cross-linking of DNA (primarily with guanine and cytosine pairs). It is also active against gm+ve bacteria and some viruses.
Increased incidence of cardiotoxicity with doxorubicin.
Hemolytic uremic syndrome (<15%), Myelosuppression (64%), Nausea/ vomiting (14%), Fever (14%), Stomatitis (4%), Increased serum creatinine (2%), Mucous membrane toxicity (4%) , Fatigue, Pulmonary toxicity, Dyspnea, Cystitis, Interstitial fibrosis, Nephrotoxicity, Amenorrhea, Alopecia, Myelosuppression, haemolytic-uraemic syndrome.

Repeated haematologic studies are necessary during treatment and for at least 7 wk after discontinuation of the drug. Discontinue use when the leucocyte count decreases to <4000/mm3 or the platelet count decreases to <150,000/mm3 or if a progressive decline in either occurs. Monitor patient for signs of renal or pulmonary toxicity.
