In an effort to improve the treatment of patients with refractory or recurrent lymphoma, we developed a protocol using cis-platinum combined with two other agents of known efficacy in these disorders but with differing side effects: VP-16 and MGBG. Twenty-six eligible patients were treated with this regimen. There were 15 men and 11 women with a median age of 54 years (22-73), and performance status of 1 (0-3). Their diagnoses were Hodgkin's disease 5 and non-Hodgkin's lymphoma [NHL] 21 which included 11 with diffuse histocytic lymphoma [DHL]. The median number of chemotherapy regimens was 2 (1-5); 12 also received radiotherapy. Twenty patients are evaluable for response: 15 NHL and 5 Hodgkin's disease. Three patients, all of whom had DHL entered complete remission (20%) with a median time to treatment failure of 7 1/2 months. Six NHL (40%) and one Hodgkin's disease (20%) patients entered a partial remission. There were three early deaths: one due to progressive disease, one to acute respiratory failure, and one with disease status undocumented. Toxicity included leukopenia, thrombocytopenia, anorexia, nausea, vomiting, stomatitis, alopecia, renal failure, profound peripheral neuropathy, and hypersensitivity vasculitis. Treatment was stopped because of the latter two. These agents are non-crossresistant with doxorubicin-containing regimens. The drugs are possibly synergistic and modestly active with moderate to severe toxicity.

Methylglyoxal bis (guanylhydrazone) (MGBG) is an inhibitor of polyamine synthesis. In vitro studies demonstrate the accumulation of some tumor cells in S and G2 phases of the cell cycle. Nineteen patients with advanced head and neck cancer were entered in a Phase II trial of MGBG. MGBG, 500 mg/M2, was administered as a brief intravenous infusion weekly for 4 weeks, then every 2 weeks. Dose modifications were based on cumulative toxicity after 2 weekly treatments. All but three patients had prior exposure to chemotherapy for disease recurrence. Of 17 patients evaluable for response and toxicity, one brief partial response was observed. The most common toxicities were mild to moderate nausea, vomiting, diarrhea, and stomatitis. Myelosuppression occurred in three patients. Dose modifications were required in four patients; a maximum dose of 700 mg/M2 was tolerated. The results of four other Phase II single and combination chemotherapy trials of MGBG in head and neck cancer are reviewed. The single agent response rate in 59 patients was 22% (range, 6%-41%). The poor response rate observed in this trial was similar to that in other trials in which a heavily pretreated group of patients was evaluated. It is concluded that single agent MGBG is not a useful drug in heavily pretreated recurrent disease patients. However, because of its biochemical effects, further testing in combination with cycle specific agents and in larger numbers of patients with minimal prior treatment may be warranted.

Thirty-nine patients received 600 mg/m2 OF MGBG intravenously every week for the treatment of advanced refractory ovarian cancer. Twenty-seven of these received adequate trials, and only two had partial remissions lasting 3 1/2 and 4 months each. Toxicity was substantial, with severe hematologic toxicity in 26%, diarrhea in 22% (severe in 7%), skin rash in 26% (severe in 7%), and vomiting in 70% (severe in 11%). Fatigue, facial paresthesias, and flushing during drug administration were frequent. It appears that MGBG in this dose and schedule has little activity against advanced ovarian cancer.

Methyl-GAG was given to 71 patients with advanced malignancies as a weekly brief infusion (30-120 minutes) or as a biweekly 24- or 120-hour infusion. Mucositis (stomatitis, pharyngitis, esophagitis, and, rarely, inflammation of other mucous membranes) was dose-limiting in all three schedules. Generalized fatigue, malaise, myalgia, dysesthesias, nausea, and vomiting were more frequent in the brief-infusion schedule. Myelosuppression was mild and not dose-related. Fever, ventricular arrhythmias, skin rash, tender swelling of the palms, neuropathy, and paralytic ileus were rare. Toxicity was increased in patients with renal insufficiency or "third-space" fluid but was not increased by hepatic dysfunction. Cumulative and overlapping toxicity was evident only in the weekly schedule. Higher doses of methyl-GAG were tolerated when the duration of infusion was increased. The recommended doses for phase II trials are 700 mg/m2 weekly as a 1-2 hour infusion, 850 mg/m2/24 hours biweekly, and 1500 mg/m2/120 hours biweekly. Therapeutic effects were seen in all schedules and included objective responses in colon carcinoma (one of 13 patients), renal cell carcinoma (one of nine), and Hodgkin's lymphoma (one of two) and objective improvements in esophageal carcinoma (one of three), endometrial carcinoma (two of two), and leiomyosarcoma (one of three).

Methyl-GAG, a polyamine synthesis inhibitor, was prospectively evaluated in the treatment of advanced renal adenocarcinoma. Twenty-five patients with measurable disease received methyl-GAG weekly at a starting dose of 500 mg/m2 iv, with dose escalation by 50 mg/m2/week (maximum dose, 825). All 25 patients are evaluable for response. Four of these patients (16%) achieved responses including three partial responses and one complete response, with a median duration of 9 weeks (range, 4--15). Nine patients (36%) remained stable and 12 (48%) had progressive disease. In the four responders, regression of disease occurred within the first 4 weeks of therapy. Toxic effects were generally mild and included nausea or vomiting (68%), myalgia (44%), mucositis (40%), neuralgia (40%), weight loss (32%), diarrhea (24%), skin rash (8%), leukopenia (8%), and genital ulcers (4%). We conclude that methyl-GAG has clear, albeit limited, activity against renal adenocarcinoma.

Fourteen patients with metastatic renal cell carcinoma received methyl-G weekly at a starting dose of 600 mg/m2 (five patients) and 500 mg/m2 (nine patients) intravenously. All 14 patients are evaluable for response and toxicity. No antitumor responses were observed. Six patients achieved stabilization of disease for 8 to 42 weeks. Toxicity was nonhematologic and included nausea or vomiting (35%), fever with shaking chills (28%), diarrhea (21%), myalgia (63%), paresthesia (49%), and bilateral foot drop (7%). Methyl-G does not appear to have activity against renal cell carcinoma.
