Twenty-one comprehensive cancer centers participated in a national reporting system of common data items, recording information on all patients seen between 1977 and 1982. There were 240,531 patients who had data abstracted. This report describes 1,479 patients with multiple myeloma. Parameters that may effect the type of treatment given during the initial episode of therapy in the center and the effect of these characteristics on survival were studied. In the univariate analysis, age, treatment, and distance traveled to the center were statistically associated with survival. In a multivariate analysis adjusting for potentially confounding covariates, blacks survive better than whites and the effects of sex and socioeconomic status (SES) on survival approach significance. Survival consistently improved with increasing distance traveled to treatment centers. This may be a serious confounding variable in assessing the results by both single and multiinstitution clinical trials.

The Eastern Cooperative Oncology Group evaluated cyclophosphamide 600 mg/m2 intravenously daily × 4 (total dose each cycle 2400 mg/m2) as an aggressive approach to the treatment of patients with advanced multiple myeloma. The overall objective response rate is 43%. This includes a 38% response rate for all previously treated patients and a 29% response rate for patients refractory to prior therapy with cyclophosphamide. The objective response duration was 3 months and the survival of responding patients 9 months. A subjective response rate of 63% was observed, characterized by effective pain relief and improved performance. Sixty‐nine percent of patients experienced leukocyte cell nadirs < 500/mm2 with a mean time to marrow recovery of 17 days. Thrombocytopenia was less severe but required platelet transfusion in 43% of patients. Bone marrow toxicity was encountered in all patients, and death in aplasia is a significant risk. Strict adherence to entry criteria, and a systematic plan for hospitalization for antibiotic and blood component support is required for treatment with this regimen.

Thirty-eight patients with advanced, progressive Hodgkin's disease who had relapsed from or who had not responded to treatment with at least two potentially curative combination chemotherapy regimens were entered into this phase 2 study. All patients received 131I antiferritin antibody administered intravenously (IV) at a dose of 30 mCi on day 0 and 20 mCi on day 5. Antibody was derived from rabbit, pig, and monkey species. Objective partial remission of measurable disease was recorded in 40% of patients. Symptomatic response was recorded in 77% of patients. Toxicity was restricted to bone marrow depression with thrombocytopenia greater than leukopenia. These responses are comparable to other reported phase 2 drugs in this patient population and subsequent trials of antibody free of radioactivity and antibody using a beta emitting isotope are being carried out to expand upon these results.
