4.2 Therapeutic Uses

Antibiotics, Antineoplastic; Nucleic Acid Synthesis Inhibitors

National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)


Mitomycin is useful for the palliative treatment of gastric adenocarcinoma, in conjunction with fluorouracil and doxorubicin. It has produced temporary beneficial effects in carcinomas of the cervix, colon, rectum, pancreas, breast, bladder, head and neck, and lung, and in melanoma. It has also shown activity against lymphomas and leukemia, particularly chronic granulocytic leukemia, but not in myeloma.

Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 1247


Thirty patients with advanced colorectal adenocarcinoma were treated by chemotherapy with an alternating regimen consisting of 5-fluorouracil mitomycin C and 5-fluorouracil dacarbazine at 3 wk intervals. ... The toxicity of this regimen was essentially digestive with 30% of grade 3 or 4 nausea and vomiting. In spite of the reported active and synergistic action of drug association in colorectal carcinoma, this treatment schedule is not better than 5-fluorouracil alone. Gastrointestinal toxicity was incr.

PMID:2496369 Herait P et al; Oncology 46 (2): 88-90 (1989)


Forty-two patients with metastatic breast cancer refractory to first line therapies were treated with combination chemotherapy with mitomycin-C and vinblastine. ... The toxicity was acceptable with 20 episodes of moderate myelosuppression (58.8%) and 2 cases with congestive heart failure that responded to medical treatment.

4.3 Drug Warning

Mitomycin is contraindicated in patients with pre-existing myelosupression & anemia.

Knoben, J.E. and P.O. Anderson (eds.) Handbook of Clinical Drug Data. 6th ed. Bethesda, MD: Drug Intelligence Publications, Inc. 1988., p. 417


Because normal defense mechanisms may be suppressed by mitomycin therapy, the patient's antibody response to the vaccine may be decreased. The interval between discontinuation of medications that cause immunosuppression and restoration of the patient's ability to respond to the vaccine depends on the intensity and type of immunosuppression-causing medication used, the underlying disease, and other factors; estimates vary from 3 months to 1 year.

USP Convention. USPDI - Drug Information for the Health Care Professional. 16th ed. Volume I. Rockville, MD: U.S. Pharmaceutical Convention, Inc. 1996 (Plus updates)., p. 2088


cBecause normal defense mechanisms may be suppressed by mitomycin therapy, concurrent use with a live virus vaccine may potentiate the replication of the vaccine virus, may increase the side/adverse effects of the vaccine virus, and/or may decrease the patient's antibody response to the vaccine; immunization of these patients should be undertaken only with extreme caution after careful review of the patient's hematologic status and only with the knowledge and consent of the physician managing the cytarabine therapy. The interval between discontinuation of medication that cause immunosuppression and restoration of the patient's ability to respond to the vaccine depends on the intensity and type of immunosuppression-causing medications used, the underlying disease, and other factors; estimates vary from 3 months to 1 year. Patients with leukemia in remission should not receive live virus vaccine until at least 3 months after their last chemotherapy. In addition, immunization with oral polio-virus vaccine should be postponed in persons in close contact with the patient, especially family members.

Gonadal suppression, resulting in amenorrhea or azoospermia, may occur in patients taking antineoplastic therapy, especially with the alkylating agents. In general, these effects appear to be related to dose and length of therapy and may be irreversible. Prediction of the degree of testicular or ovarian function impairment is complicated by the common use of combinations of several antineoplastics, which makes it difficult to assess the effects of individual agents.

4.4 Drug Indication

For treatment of malignant neoplasm of lip, oral cavity, pharynx, digestive organs, peritoneum, female breast, and urinary bladder. Also used as an adjunct to ab externo glaucoma surgery. Mitomycin is also indicated as a pyelocalyceal solution for the treatment of adults with low-grade upper tract urothelial cancer (LG-UTUC).

5 Pharmacology and Biochemistry
5.1 Pharmacology

Mitomycin is one of the older chemotherapy drugs, which has been around and in use for decades. It is an antibiotic which has been shown to have antitumor activity. Mitomycin selectively inhibits the synthesis of deoxyribonucleic acid (DNA). The guanine and cytosine content correlates with the degree of mitomycin-induced cross-linking. At high concentrations of the drug, cellular RNA and protein synthesis are also suppressed. Mitomycin has been shown in vitro to inhibit B cell, T cell, and macrophage proliferation and impair antigen presentation, as well as the secretion of interferon gamma, TNFa, and IL-2.


5.2 MeSH Pharmacological Classification

Alkylating Agents

Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases. (See all compounds classified as Alkylating Agents.)


Antibiotics, Antineoplastic

Chemical substances, produced by microorganisms, inhibiting or preventing the proliferation of neoplasms. (See all compounds classified as Antibiotics, Antineoplastic.)


Nucleic Acid Synthesis Inhibitors

Compounds that inhibit cell production of DNA or RNA. (See all compounds classified as Nucleic Acid Synthesis Inhibitors.)


Cross-Linking Reagents

Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other. (See all compounds classified as Cross-Linking Reagents.)

Mitomycin is absorbed inconsistently from the gastrointestinal tract, and it is therefore administered intravenously. It disappears rapidly from the blood after injection. Peak concentrations in plasma are 0.4 ug/ml after doses of 20 mg/m sq ... The drug is widely distributed throughout the body but is not detected in the brain.

Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 1247


In animals, highest mitomycin concentrations are found in the kidneys, followed by muscles, eyes, lung, intestines, and stomach. The drug is not detectable in the liver, spleen, or brain which rapidly inactivate mitomycin. Higher concentrations of the drug are generally present in cancer tissues than in normal tissues.

5.8 Mechanism of Action

Mitomycin is activated in vivo to a bifunctional and trifunctional alkylating agent. Binding to DNA leads to cross-linking and inhibition of DNA synthesis and function. Mitomycin is cell cycle phase-nonspecific.


... REACTS WITH BACTERIAL DNA BUT NOT WITH ISOLATED DNA, UNLESS ... REDUCING SYSTEM IS ADDED. CROSS LINKING EFFICIENCY ... INCR IN ISOLATED BACTERIAL DNA CONTAINING INCR AMT OF CYTOSINE & GUANOSINE.

ITS REDUCED FORM CONTAINS INDOLE GROUP EMBODYING ALLYLIC CARBAMATE RESIDUE. ANTIBIOTIC IS CYTOTOXIC & CARCINOGENIC BUT IS INACTIVE AS CYTOTOXIC AGENT UNLESS REDUCED ... IT ACTS AS DIFUNCTIONAL AGENT IN CROSS LINKING DNA.

The drug inhibits DNA synthesis and cross-links DNA at the N6 position of adenine and at the O6 and N2 positions of guanine. In addition, single-strand breakage of DNA is caused by reduced mitomycin; this can be prevented by free radical scavengers. Its action is most prominent during the late G1 and early S phases of the cell cycle.
