In an attempt to further define the nature, occurrence, and relative incidence of splenic sarcoid-like granulomas, 412 splenectomy specimens were studied. In addition to their occurrence in sarcoidosis, granulomas were found in patients with Hodgkin's disease, chronic uremia, non-Hodgkin's lymphoma, and selective IgA deficiency. The inability to demonstrate a specific responsible organism suggests that the lesion is not of infectious cause. The location of the lesions in the areas of antigen-trapping in the spleen, and their occurrence in both neoplastic and nonneoplastic diseases associated with abnormal or defective immunity suggests that they represent morphologic evidence of a nonspecific defect in antigen processing.

The diameters of the cell nuclei were measured in imprint preparations of eight tonsils and 28 lymph nodes, each specimen being from a separate patient. The lymph nodes were from cases of Hodgkin's disease (HD), non-Hodgkin's lymphoma (NHL), and reactive benign states. The nuclear diameters were measured by means of an image-analysing device, the Zeiss Microvideomat. For accurate measurements, the cells had to be well separated, and tissue sections could not be used because the close juxtaposition of nuclei gave erroneous readings. However, cell imprints proved suitable. The results show that the mean nuclear diameters for the HD, NHL, and reactive groups differ and show a considerable scatter. However, the distributions for the NHL and reactive nodes are sufficiently different to suggest that the method may have diagnostic value for the former.

Serum of 70 patients with malignant lymphoma was tested for concentration of ferritin by immunoradiometric assay. Serum of patients with Hodgkin's disease showed an apparently increased ferritin concentration only in the stage III and IV. Concentration of serum ferritin was found normal in patients with chronic lymphocytic leukemia and non-Hodgkin's lymphoma of low malignancy. Among patients with non-Hodgkin's lymphome of high malignancy only one who suffered from advanced immunoblastic sarcoma showed increased concentration of serum ferritin. Patients with elevated concentration of serum ferritin had a decreased level of serum iron and showed also anemia. Their bone marrow reticulum was rich in dyeing iron. These results suggest that hyperferritinemia in patients with advanced Hodgkin's disease is related to a lack of release of iron from reticuloendothelial system.

Tasmania, an island state of the Australian Commonwealth with a population of 400,000 of predominantly Anglo-Saxon heritage, has relatively centralized oncology services. A study was undertaken of all patients known in December 1971 and of all new cases diagnosed since January 1972 with all forms of leukemia, Hodgkin's disease, non-Hodgkin's lymphoma, myeloma, and other myeloproliferative and lymphoproliferative disorders. Data were obtained with respect to lifetime residential and occupational history, schools attended, and known familial cases of any of the myeloproliferative and lymphoproliferative disorders.

In order to assess its potential uses in the staging and treatment planning of lymphoma, CT was performed in 27 newly diagnosed, previously untreated patients with Hodgkin's disease or non-Hodgkin's lymphoma; 18 staging laparotomies provided pathologic correlations. CT detected and defined disease in areas not well evaluated by conventional techniques (high para-aortic, mesenteric, splenic hilar nodes). CT interpretation of splenic size and weight correlated well with splenic weight confirmed at pathology. Nodules were identified in several spleens containing foci of lymphoma.

In patients with Hodgkin's disease or non-Hodgkin's lymphoma, the etiology of low peripheral blood counts is often difficult to determine. Often it is based on the results of a "random" bone marrow biopsy and/or aspirate, plus evaluation of circulating peripheral blood elements. However, these tests may be misleading. The present study evaluates the usefulness of 111Indium chloride bone marrow scanning in conjunction with marrow biopsies in distinguishing intrinsic from extrinsic causes for low peripheral blood counts. Thirty consecutive patients with Hodgkin's disease or non-Hodgkin's lymphoma, presenting with low peripheral blood counts and without any form of antineoplastic treatment for at least 5 weeks, were analyzed. Scan ratings were felt to be clinically accurate in 27 of the 30 patients analyzed (90%). In 18 patients (60%), the scan provided information which was not provided by any other standard test. 111Indium chloride scanning in conjunction with a marrow biopsy appears to be a useful, accurate means of evaluating bone marrow function in patients with depressed peripheral blood counts.

This study was designed to delineate the role of laparotomy for staging in the management of lymphomas and to determine the accuracy of nonsurgical staging procedures. Fifty-four untreated patients with diagnoses of Hodgkin's disease or non-Hodgkin's lymphoma had extensive physical, laboratory, roentgenologic, scintigraphic, nonsurgical and surgical staging evaluation. Forty-five out of 54 patients had clinical Stage I and II disease; clinical Stage IV patients were excluded. One out of eight enlarged spleens, 12 out of 46 normal spleens, none of four enlarged livers and four out of 50 normal livers were positive at laparotomy. None of the preoperative needle biopsies of the liver and iliac crest was positive for lymphoma. The pathologic stage was advanced in six out of 25 of clinical Stage I, six out of 20 Stage II and two out of nine of Stage III. 67Ga scanning and lymphography were accurate in 16 out of 30 and 24 out of 45 patients, respectively. There was no mortality, but morbidity was limited to atelectasis, thrombophlebitis and subphrenic abscess in three patients, respectively. Only when treatment regimen is stage-dependent and only if nonsurgical staging procedures have reliably failed to rule out disseminated disease, then laparotomy for staging indicated in localized lymphomas. Laparotomy for staging should not be done when the treatment plan is not altered by staging data or when there is a medical contraindication or when evidence of disseminated disease has been reliably and consistently obtained by nonsurgical methods as needle biopsies of the liver and bone, lymphography, scintigraphic studies and laparoscopy.

Phase II studies utilizing VP-16-213 in the treatment of 56 patients with malignant lymphoma and 29 patients with malignant melanoma were carried out by the Southwest Oncology Group. All patients had received extensive prior therapy. The initial dose of VP-16-213 administered was 45 mg/m2 by iv infusion over 30-60 minutes on Days 1-5 every 3 weeks but, because, of severe myelosuppression in the lymphoma group, the dose was subsequently reduced to 35 mg/m2. Only three partial regressions lasting 6, 2, and 1 months were noted in 17 patients with Hodgkin's disease. No favorable responses were noted in 35 patients with non-Hodgkin's lymphoma including 16 with the diffuse histiocytic type. No responses were noted in patients with melanoma. The major toxic effect was myelosuppression. VP-16-213 appears to lack significant effectiveness in these previously treated disease.

Thirty-six patients treated for Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) who had been in complete remission and off all therapy for greater than two years were examined for evidence of immunosuppression. All patients were found to have marked depression of their lymphocyte blastogenic response to phytohemagglutinin (PHA) and of their skin test responses. No abnormalities of serum protein or immunoglobulins were found. T cells were significantly lower than normal in patients who had had Hodgkin's disease, but not in those who had had NHL. B cells, on the other hand, were significantly elevated in both groups. Splenectomy elevated the total lymphocyte count, while those who had not had a splenectomy had lower than normal lymphocyte counts. B cells were elevated while T cells tended to be lower in both splenectomy and nonsplenectomy groups, though only in the nonsplenectomized patients did this reach statistical significance. PHA response tended to be higher in patients with less advanced disease and less extensive treatment than in those with more advanced disease and more extensive treatment, although there was no statistically significant difference. Skin test response though, was shown to correlate well with both stage of disease at diagnosis and extent of treatment.

A cluster of Hodgkin's disease (HD) cases occurred in a small rural town of 1250 people. Ten cases of HD and three cases of non-Hodgkin's lymphoma were identified within or linked to this town since 1954. This town therefore had an average annual incidence and mortality for HD of 29.3 and 16.7 cases per 100,000 population, respectively. Most cases of HD demonstrated case-contact associations, and a distinct geographic distribution. The data suggested that there was an environmental agent responsible for the elevated rates of HD. One unique aspect of this cluster is that this town has only one industry, a large grain elevator. The cases closely surrounded this elevator. We postulate that residents of the town are subject to chronic immune stimulation from mitogenic substances in this environment. These agents may alter immunity in the residents of this community and predispose them to acquiring HD.
