By evaluating the results obtained in 50 patients the authors stated that VM-26 given in combination with Natulan and Prednisolone is a drug of value in the therapy of generalized Hodgkin's disease. It cause milder side effects than drugs previously used in combination therapy. Complete or partial remissions were obtained in 84% of patients treated. 75% of the therapy-resistant cases proved to be Hodgkin's sarcoma by the postmortem examination. Remission lasted longer in stage III than in stage IV and the previously untreated patients responded better than the treated one. Definite correlation could not be revealed between histologic type and duration of remission.

Procarbazine hydrochloride (PCZ), a chemotherapeutic agent used extensively to treat Hodgkins disease and other tumors, induces leukemia, lymphoma, mammary gland and other solid tumors in rodents and non-human primates and is strongly implicated as a leukemogen in humans. Lipotrope (choline and methionine) deficiency is a powerful potentiator of chemical carcinogenesis in liver and, under some conditions, in other tissues in rodents. Methotrexate (MTX), another commonly used chemotherapeutic agent, interferes with one-carbon metabolism and limits availability of lipotropes. Studies of PCZ carcinogenesis in lipotrope-deficient or MTX-treated male rats are reported, showing that both deficiency and MTX increased PCZ carcinogenicity in the mammary gland. In addition, PCZ was found to induce abnormalities of hepatic choline metabolism. Weanling male Sprague-Dawley rats were fed control (C) or lipotrope-deficient (D) diet. After 3 weeks, C and D rats were given PCZ, MTX, the two drugs together or 0.9% saline by i.p. injection. Doses were 0.2 or 0.5 mg MTX/kg or 25 mg PCZ/kg, given 2 or 3 days per week for 5 or 14 weeks. After 5 weeks of drug treatment livers were assayed for choline, phosphatidylcholine, phosphocholine (PCho), glycerophosphocholine and betaine. PCZ perturbed choline metabolism, increasing hepatic choline and PCho in deficient or MTX-treated rats and, to a smaller extent, in rats fed control diet. MTX markedly enhanced the effect of PCZ on choline metabolism. PCZ-induced mammary tumor incidence was increased 50-70% by lipotrope deficiency or by MTX. In PCZ-treated rats, cumulative probability of bearing a mammary tumor was significantly increased by lipotrope deficiency (P = 0.05), and was increased similarly but not significantly by MTX (P = 0.1). Cumulative tumor numbers per group in PCZ-treated rats were significantly greater in both deficient and MTX-treated rats compared to rats fed control diet (P less than 0.005). Incidences of leukemia, lymphoma and Zymbal's gland tumors induced by PCZ were not significantly altered by diet or MTX.

Procarbazine hydrochloride is an oral alkylating agent with activity against lymphoma. It is most commonly used in the treatment of Hodgkin's disease. The use of procarbazine-containing chemotherapeutic regimens in non-Hodgkin's lymphoma fell out of favor with the advent of CHOP. We report two patients with relapsed and/or refractory follicular lymphoma that achieved a complete and durable remission with a prolonged course of daily procarbazine.

Elderly Hodgkin lymphoma (HL), commonly defined as occuring in patients over 60 to 65 years of age, is an uncommon disease. In population-based studies, the proportion of HL patients over age 60 years has rangedfrom 15% to 30%. However, the proportion of patients over age 60 years in clinical trials has been considerably lower, typically constituting < 5% to 10% of participants. Elderly HL patients commonly present with mixed cellularity histology, B symptoms, advanced stage, and Epstein-Barr virus-positive disease. Progression-free and overall survival rates for elderly HL patients are disproportionately inferior to those of younger patients. Generally, treatment of elderly HL for all disease stages should be given with curative intent, but more effective, tolerable therapeutic regimens are needed. No standard treatment recommendations exist for elderly HL Bleomycin-containing regimens including ABVD (doxorubicin [Adriamycin], bleomycin, vinblastine, dacarbazine) are associated with pulmonary toxicity, and intensive therapy such as BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine [Oncovin], procarbazine [Matulane], prednisone) is poorly tolerated, whereas less-intensive regimens such as CVP/CEB (chlorambucil [Leukeran], vinblastine, procarbazine, prednisone, cyclophosphamide, etoposide, bleomycin) and ChlVPP (chlorambucil, vinblastine, procarbazine, prednisolone) appear to be less effective than anthracycline-based regimens. Recent data using CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) in this population merit further investigation. In addition, further evaluation of the prognostic value of early PET in elderly HL is warranted. Continued multicenter collaborations with prospective clinical trials, including formal assessment of comorbidity and functional status, will be critical to the successful study of elderly HL.

Procarbazine hydrochloride is an oral alkylating agent primarily used as a component of chemotherapy regimens for Hodgkin's lymphoma, as well as in regimens for primary central nervous system lymphoma and high-grade gliomas. Although the prescribing information for procarbazine lists hepatic dysfunction as a potential adverse reaction, we found only one published report with a probable link between procarbazine and liver injury. We describe a 65-year-old man who developed liver injury due to procarbazine during salvage chemotherapy for non-Hodgkin's lymphoma. The patient had no preexisting liver disease, his lymphoma was without hepatic involvement, and no liver injury developed after initial chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). Due to relapse of his non-Hodgkin's lymphoma, salvage chemotherapy with C-MOPP-R (cyclophosphamide, vincristine, procarbazine, prednisone, and rituximab) was administered, and the patient developed fever and aminotransferase level elevation during the second cycle. After discontinuation of all drug therapy, exclusion of other potential etiologies, and resolution of hepatic injury, the patient was rechallenged with procarbazine and again experienced fever with aminotransferase level elevation. His aminotransferase levels promptly returned to normal after discontinuation of procarbazine, and he experienced no further evidence of liver disease. Use of validated scoring systems of drug-induced liver injury indicated a definitive association between the patient's hepatic injury and procarbazine. Based on our experience with this patient, periodic assessment of hepatic function, as suggested in the package insert, is recommended in patients receiving procarbazine.
