Preclinical studies suggest that the combination of Tumor Necrosis Factor (TNF) and mitoxantrone have a synergistic effect. On this basis, we conducted a study to verify the feasibility of the intraperitoneal administration of these drugs in patients with malignant ascites. Cohorts of three patients were treated with a fixed dose of mitoxantrone (6 mg/m2) and escalating doses of TNF (from 60 up to 200 mcg/m2), intraperitoneally, given for two hours once a week for at least four weeks. Seventeen patients with malignant ascites entered into the study. All but two patients received the planned four cycles. Sixty-six cycles were given. The most common side effects were fever (21-44% of cycles), chills (8-44%), fatigue (19-33%), loss of appetite (17-57%), malaise (25-43%), myalgia (33%), pain injection (25-83%), nausea/vomiting (33-64%). Severe fatigue, malaise and anorexia were observed only at doses of 200 mcg/m2 of TNF. Weekly intraperitoneal administration of mitoxantrone (6 mg/m2) and TNF (200 mcg/m2) is a feasible regimen with acceptable toxicity. The activity of this combination should be studied in properly designed phase II trials. | lld:pubmed |
