The architectural arrangement of the neoplastic cells and their cytologic identification form the histologic basis of the Rappaport classification of non-Hodgkin's lymphomas clinical studies have shown the favorable prognosis of the nodular lymphomas while the diffuse lymphomas irrespective of cell type have a poor prognosis. Several recent studies have shown that pathologists can identify the nodular and diffuse patterns with a high degree of reproducibility. The cytologic subclassification has, however, not achieved a similar high degree of reproducibility. The Southwest Oncology Group study has shown the most reproducible subgroups to be the nodular poorly differentiated lymphocytic malignant lymphoma (ML) and the diffuse histiocytic ML. The clinical significance of the Rappaport classification when applied to childhood lymphomas is not as clear as in adult lymphomas. In view of the recent description of a new clinicopathologic entity primarily in children and adolescents (ie, lymphoblastic ML), IT IS APPARENT THAT THE CHILDHOOD LYMPHOMAS Will have to be examined more critically in order to determine the clinical significance of this classification. Although some have proposed new classifications of these lymphomas based upon immunologic identification of cell origin, none have been shown to be of clinical significance. Based on recent immunologic and clinical studies, a modified classification of the non-Hodgkin's lymphoma is proposed which does not alter its clinical usefulness.

This paper briefly reviews the various classifications proposed as alternatives to that of Rappaport. Rappaport's classification is valuable because it is applicable to clinicopathologic studies, but there are areas of contention. Following the Airlie Conference, which failed to resolve the current controversy about classification, the National Cancer Institute proposed to support a retrospective study of 1000 cases of non-Hodgkin's lymphoma, during which the various classifications will be applied to the biopsy slides by a selected panel of pathologists. It is hoped that this study will meet the urgent need for a classification which will eliminate controversial terminology and will employ terms acceptable to pathologists in their daily diagnostic work and to hematologists and oncologists burdened with the choice of therapy for patients affected by the non-Hodgkin's lymphomas.

75 cases treated between 1970 and 1976 for malignant follicular non-Hodgkin's lymphoma were analysed for their cardinal signs. Contrary to non-Hodgkin's lymphoma of "higher malignancy degree", the average age of patients with malignant follicular non-Hodgkin's lymphoma is generally over 50 years, being more common in females. By the time the diagnosis is made a generalised stage has usually been reached. In the described group of patients the five-year survival rate was 65%, but compared with the malignant lymphoma of higher malignancy the prognosis is often complicated by secondary diseases resulting from the higher age. The findings confirm the need for histological sub-classification of malignant non-Hodgkin's lymphoma.

Lymphoma Pathology Panel and Repository (LPPR) review of pathologic material from 354 patients registered on Southwest Oncology Group clinical trials substantiated the diagnosis of Hodgkin's disease (Lukes-Butler classification) in 175 (94%) of 186 cases and the diagnosis of non-Hodgkin's lymphoma (Rappaport classification) in 162 (96%) of 168 cases. However, complete agreement (type and subtype) between institutional and LPPR review diagnoses was found in only 66% of confirmed cases of Hodgkin's disease and in only 58% of confirmed cases of non-Hodgkin's lymphomas. In 26 (16%) of 160 cases of non-Hodgkin's lymphoma, the initial interpretation of pattern (nodular vs diffuse) differed: 20 (25%) of 81 nodular lymphomas had been thought to be diffuse and 6 (8%) of 79 diffuse lymphomas had been diagnosed as nodular. The frequency with which initial diagnoses were confirmed on LPPR review was highest for three subtypes of lymphoma: nodular sclerosis Hodgkin's disease (88%), diffuse histiocytic lymphoma (86%), and nodular lymphocytic lymphoma (78%); rates of confirmation for all other subtypes ranged from 13-50%. The results of this analysis emphasize the necessity of having pathologic review of all cases entered on major lymphoma studies so that comparability of cases can be assured and the results of those studies placed in proper perspective.

Piperazinedione given iv once every 3-4 weeks at a starting dose of 9-12 mg/m2 (4.5-12 mg/m2 for patients with myeloma) was evaluated in a Southwest Oncology Group phase II study for patients with far-advanced refractory lymphoma or multiple myeloma. Among 36 patients fully evaluable for tumor response (adequate trial), partial responses were observed in five (71%) of seven patients with Hodgkin's disease, in three (19%) of 16 patients with non-Hodgkin's lymphoma, and in none of 13 patients with multiple myeloma. Response was observed by the time of the second (five patients) or third (three patients) course. The median duration of response was 3.7 months (range, 1-17+ months). The dose-limiting toxic effects were hematologic, with 18 (50%) of 36 patients evaluable for toxicity experiencing severe leukopenia (wbc count less than 2000/mm3) and 22 (61%) experiencing severe thrombocytopenia (platelet count less than 50,000/mm3). Twenty patients had a decrease from their pretreatment hemoglobin level of greater than or equal to 2 g/100 ml. Hematologic toxic effects were often unpredictable and in several patients quite prolonged. This study indicates that piperazinedione had definite antitumor activity in patients with Hodgkin's disease and further trials in this disease using the drug at a reduced dose in combination with other effective drugs appear warranted.

Methotrexate is now used widely for the treatment of acute leukemia, non-Hodgkin's lymphoma, osteogenic sarcoma, choriocarcinoma, breast carcinoma, pulmonary and epidermoid carcinoma, and intrathecal chemotherapy. It is also useful in bone marrow transplantation, severe psoriasis, rheumatoid arthritis, dermatomyositis, Wegener's granulomatosis and sarcoidosis. The recent dramatic intensification of methotrexate therapy can be attributed in part to advances in our understanding of the clinical pharmacology of the folate antagonists, as well as to the combination of positive results and their effective dissemination to medical oncologists. The review summarizes the pharmacologic findings and illustrates how they are currently being applied to the treatment of malignant disease.

Levels of two fusosyltransferases were measured in plasmas of patients with non-Hodgkin's lymphoma at different phases of the disease. The level of a GDP-fucose: galactoside fucosyltransferase (EC 2.4.1.69) was found elevated in nonresponding patients and was correlated with estimated tumor burden. Enzyme levels in the normal range were found in patients in remission, maintained on chemotherapy, or unmaintained. The plasma level of a GDP-fucose; N-acetylglucosaminide fucosyltransferase (EC 2.4.1.68) was elevated in all individuals receiving drug therapy regardless of diesease status, but returned to normal levels during unmaintained remissions.

We have conducted a phase I clinical trial of maytansine, a plant alkaloid with potent tubulin-binding activity. For evaluation of toxicity, the schedule of drug administration consisted of a single iv infusion given every 3 weeks. Dose-limiting toxicity was observed at 2 mg/m2, and was manifested as profound weakness, diarrhea, nausea, and vomiting. Symptoms persisted for 3--14 days after drug administration. No consistent myelosuppression occurred at any dose level. Responses were observed in two patients (one each with non-Hodgkin's lymphoma and ovarian cancer) who were treated on the every-3-week schedule, as well as in two patients with acute lymphocytic leukemia treated with single weekly doses. Three of the four responding patients had received extensive prior treatment with vincristine, and two were clearly resistant to vincristine.

We studied the clinical and pathological features of six cases of non-Hodgkin's lymphoma (diffuse undifferentiated in four cases and diffuse histiocytic in two cases) occuring in patients treated for Hodgkin's disease. All six patients had received both radiation and chemotherapy. Abdominal or gastrointestinal involvement was present in five of the six cases. None of the patients had evidence of Hodgkin's disease when the diagnosis of non-Hodgkin's lymphoma was made. Five of the six patients were among a study group of 579 patients with Hodgkin's disease, prospectively followed since diagnosis. At 10 years the actuarial risk of development of non-Hodgkin's lymphoma in this study group is 4.4 per cent (1.2 to 15.0) (per cent probability with 95 per cent confidence limits) and is similar to that of developing acute leukemia: 2.0 per cent (0.3 to 12.9). Non-Hodgkin's lymphoma is a second tumor that may occur late in the course of patients treated for Hodgkin's disease--particularly in patients who have received both radiation therapy and chemotherapy. Like acute leukemia, non-Hodgkin's lymphoma may be another cancer that represents a substantial late risk of combined-modality therapy.

Vertical studies indicate that, in general, acute phase reactant proteins (APRP) reflect disease activity in both Hodgkin's disease and non-Hodgkin's lymphoma. Longitudinal studies of the selected APRP profile demonstrate the following: 1. The stable profile is characteristic of remission. 2. Considerable elevation of APRPs coincides with relapsed disease. 3. An unstable profile is a feature of relapsing disease and may give early warning of relapse. 4. Patients responding inadequately to treatment frequently have unstable APRP profiles.
