Sixty-one of 76 patients entered on a prospective randomized trial of neocarzinostatin ( NCZ ) versus m-AMSA or doxorubicin were eligible for analysis. Among these 61 patients at least one episode of severe toxicity was documented in 39% of patients on NCZ and 58% on m-AMSA. Fifty-one of the 61 patients were previously untreated with chemotherapy. Among these 51 patients objective response was documented in two of 25 patients treated with NCZ , none of 17 treated with m-AMSA, and one of nine treated with doxorubicin. Among previously untreated North American and European (NA/E) patients the median survival times were: NCZ 11 weeks and m-AMSA 12 weeks. The data on South African (SA) patients with similar entrance criteria entered on earlier Eastern Cooperative Oncology Group trials were analyzed with that from the randomized trial and show that for SA patients the median survival times were: NCZ , 11 weeks (31 patients); m-AMSA, 13 weeks (33 patients); and doxorubicin, 15 weeks (29 patients).

Multiple myeloma, a hematological malignancy typified by the clonal expansion of bone marrow plasma cells, contributes to one percent of all malignancies worldwide. Despite myeloma only contributing to 10% of all hematological malignancies, it carries significant morbidity owing to its heterogenous presentation from orthopedic manifestations to renal sequelae. Patients with the disease can be risk stratified into high risk categories by the presence of various cytogenetic and other laboratory measures, albeit expensive. The albumin:globulin ratio and its inverse the globulin:albumin ratio is proposed as a means of predicting survival in this group of patients as a cheaper and more accessible marker of disease.
