Urinary alkalinization with oral sodium bicarbonate has decreased the incidence of acute nephrotoxicity and subsequent myelotoxicity in 18 adults receiving high-dose methotrexate with calcium leucovorin rescue (MTX-LCV) weekly in doses of 1-7.5 g/m2. Close monitoring of 24-hour serum creatinine and MTX levels can predict patients at risk for serious toxicity. By a prompt (24-36 hours) increase in the LCV dose rate, hematologic and biochemical evidence of myelosuppression has been prevented. Kinetic parameters in serum and lumbar cerebrospinal fluid (CSF) were studied in two patients following iv injection of 3 and 7.5 g/m2 respectively. Lumbar CSF MTX concentrations greater than 1 muM are achieved. The half-life of MTX in the CSF (11.95 hours) is twice as long as the serum half-life. In the presence of carcinomatous meningitis, further delay in the clearance of MTX from the CSF was seen. With weekly MTX-LCV, there have been four objective responses in six patients with non-Hodgkin's lymphoma in CNS relapse, including complete regression in two. It is suggested that therapeutic concentrations can be achieved in the central nervous system following MTX-LCV.

Antiserum was generated in rabbits to the RPMI 8226 tissue culture line of human myeloma cells, and its reactions with fixed smears of bone marrow aspirates from patients with multiple myeloma, macroglobulinemia, benign monoclonal gammopathy (BMG), leukemia, and nonneoplastic plasmacyosis was assessed by indirect immunofluorescence. After absorption with preparations of bone marrow from normal individuals, the antiserum reacted to a significantly higher titer with a specific subpopulation of plasma cells in smears from 81% of patients having multiple myeloma and 50% of patients having BMG than with cells in smears of bone marrow aspirates from normal individuals or patients having leukemia or nonneoplastic plasmacytosis, or than with cells in smears of peripheral blood from patients having Hodgkin's and non-Hodgkin's lymphoma. Absorption of the antiserum with RPMI 8226 cells or with a bone marrow preparation from a patient with multiple myeloma but not the Jijoye line of Burkitt's lymphoma reduced reactivity for cells in myeloma bone marrow. The antiserum reacted at a lower titer with the Jijoye and EB-3 lines of Burkitt's lymphoma, the RPMI 4098 cell line of normal human lymphocytes, and culture lines of human melanoma and osteogenic sarcoma than with the RPMI 8226 cells or bone marrow from certain patients having multiple myeloma. Approximately 50% of the cells reactive with antiserum to RPMI 8226 cells in the bone marrow of patients with multiple myeloma were not producing immunoglobulin, as assessed by double immunofluorescence assay. The data suggested that a subpopulation of plasma cells in the bone marrow of patients with multiple myeloma possesses a tumor-associated antigen.

A modified electrophoretic mobility (EM) test was performed in 150 children to examine their lymphocyte sensitization to myelin basic protein (encephalitogenic factor). Measurements in the cytopherometer were facilitated by using devitalized sheep erythrocytes as indicator particles instead of macrophages. A significant decrease in EM was found in 29/30 children with acute lymphoblastic leukaemia and in 67/75 children with solid tumours, thus giving a false negative rate in malignant disease of 9/105=8-6%, as compared to 6 false positives among 45 children with non-malignant disorders; 5 of the later "false/positive" 6 patients had autoimmune disease. Results of the EM test in the children with leukaemia were compared with those in 9 patients with non-Hodgkin's lymphoma and 2 with Hodgkin's disease at different stages, but no striking change was seen between different diseases, or after cessation of long-term immunosuppressive chemotherapy. Percentage of "slowing" ranged from 4 to 30%. These results indicate that patients with lymphoid malignancies still have lymphocytes which had been sensitized by a common antigen of the malignant cell clone at the beginning of the disease. The EM test, furthermore, could serve as an additional diagnostic aid in differentiating benign from malignant masses in the abdomen, extremities or intracranial disease.

Total-body scintigraphy with 111In-labeled bleomycin was performed in 66 patients with malignant solid tumors and systemic diseases of the lymphatic pathways (Hodgkin's lymphoma and non-Hodgkin's lymphoma). In 38 (58%) of 66 cases positive information was correct. In 12 (18%) of 66, scintigraphic information was correctly negative. With 16 out of 66 (24%), false positive or false negative informations were obtained.

The Southwest Oncology Group (SWOG) has completed five studies of high-dose intermittent combination chemotherapy for the management of advanced (stage III and IV) non-Hodgkin's lymphoma involving 1143 patients from May 1966 to September 1974. Lack of uniform histopathologic interpretation precludes precise analysis of these data. Although there has been little change in complete response duration over the years of this study, there has been an overall improvement in response rate and survival though there is no statistically significant improvement in the best overall survival when compared to the Stanford experience in stage III and IV disease (1960-71). The response rate and survival in diffuse histiocytic lymphoma have improved since the first study. There is definite evidence of a plateau in the survival curve beyond 2 years. The percentage of survival at which the plateau appears has increased over the years to 40% in the most recent studies, and the survival is suggestively better than the Stanford experience (P = 0.09). Over the years there has been a distinct improvement in response rate and survival of patients with nodular lymphocytic lymphoma, although the best SWOG survival is no different than the Stanford experience (P = 0.36).

This paper presents an overview of four Cancer and Leukemia Group B studies in 1266 patients with stage III-IV non-Hodgkin's lymphoma. The cases were analyzed across protocols; the major prognostic determinants were prior chemotherapy, age, and histology. The four studies proved that cyclophosphamide maintenance was superior to no maintenance even after prolonged intensive induction chemotherapy. Furthermore, the reinforcement program of monthly pulse doses of vincristine and prednisone, whose value was established in the treatment of acute leukemia, led to highly significant improvement in remission duration and survival. Other facets of the chemotherapy programs are still being subjected to analysis, but this report sets out some preliminary conclusions.

Lymphoblasts from 6 cases of acute lymphocytic leukemia showed a paucity of receptors for T-cells (E-rosettes) and B-cells (surface membrane immunoglobulin). In contrast, neoplastic lymphoid cells from 5 cases of non-Hodgkin's lymphoma demonstrated that 4 cases could be listed as B cell proliferations and 1 case as a T-cell tumor, Anomalous HLA cytotoxic reactions were observed in all 6 cases of acute lymphocytic leukemia and probably in 1 case of non-Hodgkin's lymphoma. When the HLA antisera was absorbed of its HLA specificity, lymphoblast cytotoxicity was still observed, indicating the presence of some contaminating nonHLA antibody in HLA antisera. Severson et al. (3) demonstrated the presence of anti-B-cell activity in 2 of the 4 antisera used in this study. Lymphoblasts failed to stimulate autologous peripheral blood remission lymphocytes and neoplastic lymphoid cells did not stimulate autologous peripheral blood lymphocytes in mixed lymphocyte culture, indicating the lack of a neoantigen as measured by this technique. However lymphoblasts from 4 cases of acute lymphocytic leukemia and neoplastic lymphoid cells from 2 cases of B-cell lymphoma stimulated better than they responded to allogeneic lymphocytes. The data suggest the possibility that lymphoblasts without receptors of E-rosettes and surface membrane immunoglobulin may contain B-cell antigens which crossreact with HLA antisera and vigorously stimulate allogeneic lymphocytes.

The association of non-Hodgkin's lymphoma and pregnancy is a rarely reported occurrence. We describe the case of a female patient in which a wide-spread lymphoma of mixed lymphohistiocytic diffuse type was diagnosed in the second trimester of the pregnancy. Combination chemotherapy (cyclophosphamide, vincristine, prednisone and bleomycin) was started at approximately the twenty-first week of fetal life. A prompt remission was obtained and a normal full term infant was born. Chemotherapy of progressive lymphoma in women late in pregnancy appears to be rational with little risk of fetal malformation or morbidity.

A group of 25 patients with non-Hodgkin's lymphoma was investigated. Patients diagnosed earlier were reclassified according to the Kiel system. A correlation between age distribution and histological malignancy was found. The time between the onset of symptoms and diagnosis was 1 year on an average. The majority of the patients belonged to stage IV. The survival rate was higher in the low-grade malignancy group than in the high-grade group. When assessing the prognosis, the histological classification as well as the clinical staging ought to be considered. The bone marrow was the most frequent extranodal site of involvement in stage IV. Cytopenic changes were almost invariably accompanied by bone marrow infiltration. All the 7 cases analysed for lymphocyte surface markers proved to be B cell type. No significant difference was seen between the results of single agent and combined chemotherapy.

As a part of an ongoing prospective controlled trial, the Southwest Oncology Group compared the results of treatment of advanced non-Hodgkin's lymphoma with two CHOP regimens (cyclophosphamide, adriamycin, vincristine and prednisone with either low-dose bleomycin or BCG by scarification) to a COP regimen (cyclophosphamide, vincristine and prednisone) with low-dose bleomycin (COP-Bleo). The study design emphasized histopathology review and systematic restaging to define complete remission (CR). Confirmed rates of CR for 443 evaluable patients were 59% for 286 patients receiving the CHOP regimens and 59% for 157 patients receiving COP-Bleo. Rates of CR were higher for patients with nodular lymphoma (69%) compared to those with diffuse lymphoma (54%) (p = 0.005). For patients with nodular lymphoma there was no difference in CR rates according to treatment. For patients with diffuse lymphomas the CR rate was higher with the CHOP programs (58%) than with COP-Bleo (44%) (p = 0.10). Overall duration of CR and survival was significantly longer for patients with nodular lymphoma compared to diffuse lymphoma (p less than 0.01). At this time, remission duration and survival were similar regardless of induction regimen used in patients with nodular lymphoma. However, in patients with diffuse lymphoma, the duration of CR and overall survival were improved by treatment with the CHOP regimens compared to COP-Bleo (p = 0.02). Thus, in this controlled study we have demonstrated that initial combination chemotherapy employing the CHOP regimen was a superior remission induction therapy for patients with diffuse lymphoma.
