Mitomycin should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Appropriate management of therapy and complications is possible only when adequate diagnostic and treatment facilities are readily available.
Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to overwhelming infections in an already compromised patient, is the most common and severe of the toxic effects of mitomycin.
Hemolytic uremic syndrome (HUS), a serious complication of chemotherapy, consisting primarily of microangiopathic hemolytic anemia, thrombocytopenia, and irreversible renal failure has been reported in patients receiving systemic mitomycin. The syndrome may occur at any time during systemic therapy with mitomycin as a single agent or in combination with other cytotoxic drugs; however, most cases occur at doses greater than or equal to 60 mg of mitomycin. Blood product transfusion may exacerbate the symptoms associated with this syndrome. The incidence of the syndrome has not been defined.
Dosage guidance:
Safety: Do NOT substitute mitomycin injection for mitomycin (ureteral gel) or mitomycin (ophthalmic) or vice versa; the products are different and are NOT interchangeable.
Clinical considerations: Refer to the protocol or institutional guidance for additional details of off-label dosing.

Vulvar cancer, advanced (off-label use; based on limited data): IV: 15 mg/m2 on day 1 every 14 days for 2 cycles (in combination with concomitant radiation and fluorouracil) (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
The manufacturer’s labeling states to avoid use in patients with serum creatinine >1.7 mg/dL, although no other dosage modifications are provided. The following adjustments have been recommended:
Krens 2019:
GFR ≥30 mL/minute: No need for dose adjustment is expected.
GFR <30 mL/minute: Use is not recommended.
Hemodialysis: Use is not recommended.
There are no dosage adjustments provided in the manufacturer’s labeling. However, the following adjustments have been recommended:
Mild or moderate impairment: No need for dose adjustment is expected (Ref).
Severe impairment: Consider reducing dose to 50% of the original dose (Ref).
American Society of Clinical Oncology guidelines for appropriate systemic therapy dosing in adults with cancer with a BMI ≥30 kg/m2 : Utilize patient's actual body weight for calculation of BSA- or weight-based dosing; manage regimen-related toxicities in the same manner as for patients with a BMI <30 kg/m2; if a dose reduction is utilized due to toxicity, may consider resumption of full, weight-based dosing (or previously tolerated dose level) with subsequent cycles only if dose escalations are allowed in the prescribing information, if contributing underlying factors (eg, hepatic or kidney impairment) are sufficiently resolved, AND if performance status has markedly improved or is considered adequate (Ref). Note: Some protocols may have maximum recommended doses.
Note: Other concomitant anticancer medications may also require dosage adjustment.

Miscellaneous: Fever (≤14%)
1% to 10%:
Dermatologic: Dermatologic disorder (4%; including alopecia, cellulitis at injection site, dermal ulcer, erythema of skin, skin rash, stomatitis)
Renal: Increased serum creatinine (2%)
Postmarketing:
Cardiovascular: Heart failure
Hematologic & oncologic: Thrombotic microangiopathy (including hemolytic-uremic syndrome, thrombotic thrombocytopenic purpura) (Blake-Haskins 2011, Khaja 2022, Nishiyama 2001)
Nervous system: Asthenia, malaise
Respiratory: Pulmonary toxicity (including dry cough, dyspnea, interstitial pneumonitis pulmonary infiltrates, pulmonary veno-occlusive disease) (Kunadu 2021; Saif 2010)
Hypersensitivity to mitomycin or any component of the formulation; thrombocytopenia; coagulation disorders, or other increased bleeding tendency.
Concerns related to adverse effects:
• Bladder fibrosis/contraction: Bladder fibrosis/contraction has been reported with intravesical administration (unlabeled administration route).
• Bone marrow suppression: Bone marrow suppression (thrombocytopenia and leukopenia) is common and may be severe and/or contribute to infections. WBC and platelet nadir usually occurs at 4 weeks, although may occur at up to 8 weeks; recovery occurs within 10 weeks. Fatalities due to sepsis have been reported. Myelosuppression is dose-limiting, delayed in onset, and cumulative.
• Extravasation: Mitomycin is a potent vesicant; ensure proper needle or catheter placement prior to and during infusion. Avoid extravasation. May cause necrosis and tissue sloughing; delayed erythema and/or ulceration have been reported.
• Heart failure: In a scientific statement from the American Heart Association, mitomycin has been determined to be an agent that may either cause reversible direct myocardial toxicity or exacerbate underlying myocardial dysfunction (magnitude: moderate) (AHA [Page 2016]).
• Hemolytic-uremic syndrome: Hemolytic-uremic syndrome (HUS) has been reported (incidence not defined); condition usually involves microangiopathic hemolytic anemia (hematocrit ≤25%), thrombocytopenia (≤100,000/mm3), and irreversible renal failure (serum creatinine ≥1.6 mg/dL). HUS may occur at any time (either with single agent or combination therapy), is generally associated with single doses ≥60 mg, and HUS symptoms may be exacerbated by blood transfusion. Other less common effects may include pulmonary edema, neurologic abnormalities, and hypertension. A high mortality from HUS has been reported.
• Pulmonary toxicity: Cases of acute respiratory distress syndrome (ARDS) have been reported in patients receiving mitomycin in combination with other chemotherapy who were maintained at FIO2 concentrations >50% perioperatively; use caution to provide only enough oxygen to maintain adequate arterial saturation and avoid overhydration. Pulmonary toxicity has also been reported as dyspnea with nonproductive cough and appearance of pulmonary infiltrates on radiograph.
Concurrent drug therapy issues:
• Vinca alkaloids: Shortness of breath and bronchospasm have been reported in patients receiving vinca alkaloids in combination with mitomycin or who received mitomycin previously; this acute respiratory distress has occurred within minutes to hours following the vinca alkaloid; may be managed with bronchodilators, steroids and/or oxygen.
Other warnings/precautions:
• Product selection: Mitomycin is available as mitomycin for injection, mitomycin (ophthalmic), and mitomycin (ureteral gel); the products are different and are NOT interchangeable. Verify product label prior to reconstitution and administration to prevent medication errors.

Mitomycin is expected to have a low risk of treatment-related azoospermia and male infertility (ESMO [Lambertini 2020]).
Adverse events have been observed in animal reproduction studies.

The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Mitomycin alkylates DNA to produce DNA cross-linking (primarily with guanine and cytosine pairs) and inhibits DNA and RNA synthesis. Mitomycin is not cell cycle specific but has its maximum effect against cells in late G and early S phases (Perry 2012).
