Mitoxantrone is an anthraquinone antineoplastic agent with structural similarities to doxorubicin. It has a mechanism of action similar to the anthracyclines. Its primary elimination route is hepatic metabolism (only seven percent renal excretion) and it has a terminal half-life of approximately 40 hours. Mitoxantrone has significant activity in the treatment of metastatic breast cancer, acute leukemias, and non-Hodgkin's lymphoma. Some activity is reported in head and neck cancer, Hodgkin's, myeloma, bladder cancer, prostate cancer, non-small-cell lung cancer, and liver cancer. There is a suggestion of incomplete cross-resistance between mitoxantrone and the anthracyclines in certain neoplasms. Some activity is reported with mitoxantrone in patients refractory to the anthracyclines in breast cancer, acute leukemias, and non-Hodgkin's lymphomas. The usual doses used in solid tumors and in lymphomas are mitoxantrone 12-14 mg/m2 iv q3-4wk and in leukemias is mitoxantrone 12 mg/m2/d X 5 d iv for initial induction.

Mitoxantrone at a dose of 12 mg/m2 i.v. q 3 weeks failed to produce a response in 28 adequately treated patients with measurable advanced bladder cancer. The side-effects observed in this group of patients with a good performance status were generally mild. On the basis of this negative result the use of mitoxantrone in this disease cannot be recommended.

Twenty-three patients with multifocal superficial bladder cancer (stage Ta - T1) unresponsive to at least 3 different intravesical agents, were enrolled in a phase II study in order to evaluate the prophylactic effects of intravesical Mitoxantrone (20 mg) after complete endoscopic resection (TUR) of any papillary tumor. The median follow-up was 6 months; 19 patients (82%) experienced superficial tumor recurrence, 1 patient (4%) progression to muscle invasion and 3 (13%) were disease-free, respectively. Six patients (26%) experienced local side-effects. The progression rate is acceptable; the side effects are at least similar to those available in the literature, but in our experience, Mitoxantrone has no prophylactic effects against superficial bladder cancer unresponsive to previous treatment.
