In a population-based registry, there were 580 patients with non-Hodgkin's lymphoma (NHL); 236 had primary extranodal lymphoma (41%). The initial localization of the primary extranodal lymphomas varied markedly, although 36% were primary gastrointestinal lymphomas. Histological classification was performed by a regional panel of pathologists according to the Kiel Classification and the International Working Formulation. Twelve per cent of the patients with nodal NHL had a localized disease in contrast to 40% with primary extranodal NHL. Low grade lymphomas were encountered in 30 and 10% of the patients with primary nodal and extranodal NHL, respectively. Recurrence-free survival rate for patients with localized low-grade malignancy and disseminated intermediate grade NHL is significantly better for extranodal lymphoma than for nodal NHL. Patients with disseminated high-grade extranodal NHL had the worst prognosis of all. We conclude that primary nodal and primary extranodal lymphomas should be considered as distinctive and separate entities.

In a population-based registry of 580 patients with non-Hodgkin's lymphoma (NHL) 54 patients had a primary gastric lymphoma, 42 an intestinal, 113 a primary extranodal lymphoma localised elsewhere than in the gastrointestinal tract and 371 a primary nodal NHL. Histological specimens were reviewed by a panel of pathologists and classified according to the Kiel classification and the International Working Formulation. The 4-year survival rates for primary gastric, intestinal, other extranodal and nodal NHL ranged from 50 to 60%; the 4-year recurrence-free survival rates were 50%, 35%, 19% and 19%, respectively. Among patients with localised intermediate-grade disease survival for those with gastric NHL was better than for those with intestinal lymphoma. Because it is population-based, our study cohort was not subjected to exclusion due to age, performance scale, etc. and therefore provides a more realistic picture of the occurrence and presentation of as well as prognosis for lymphoma in the population.

From 1975 to 1983, 51 patients of stage I (30) and II (21) of non-Hodgkin's lymphoma were treated with a combination chemotherapy consisting of vincristine, cyclophosphamide and prednisolone as an adjuvant therapy after radiation or operation. The following results were obtained. 1) Nine patients in stage I and 7 in stage II relapsed, so that 10 year-relapse free survival rates were 68% in stage I and 67% in stage II, respectively. 2) Three patients in nodal lymphomas, 7 in Waldeyer's ring lymphomas and 6 in extranodal lymphomas relapsed, so that 10 year-relapse free survival rates were 80%, 48% and 72%, respectively. 3) Ten year-survival rates were 86% in stage I and 70% in stage II. 4) Ten year-survival rates were 82% in nodal lymphomas, 62% in Waldeyer's ring lymphomas and 86% in extranodal lymphomas. 5) Ten patients relapsed within 1 year, 4 between 1-5 years and 2 after 5 years. Relapses occurred in other than primary sites in most patients. These results suggest that an adjuvant chemotherapy is useful for localized non-Hodgkin's lymphoma, but more intensive chemotherapy before local treatments is necessary.

Modern multidisciplinary treatment of childhood cancer has made extent of disease evaluation important for proper treatment planning. Accurate staging is essential to cooperative group studies and for comparing treatment modalities at different centers. Operative staging plays an important role where clinical or imaging methods are limited, as in abdominal Hodgkin's disease or regional nodal metastasis. Operative staging is carried out either as a special diagnostic procedure, as in lymphoma, or as part of a planned surgical resection of a solid tumor. For lymphomas: Operative staging of abdominal Hodgkin's disease is required where protocols include involved field irradiation and sparing of normal growing tissue in the child. In non-Hodgkin's lymphoma, bulky abdominal tumor may be surgically evaluated after intensive chemotherapy either in delayed primary surgery or in second look procedures. Residual tumor may be excised or tagged with clips for localized irradiation to the tumor sparing normal abdominal organs. For solid tumors: During surgical resection of neuroblastoma, Wilms' tumor and rhabdomyosarcoma, the correct procedure involves regional staging either by formal node dissections or by multiple biopsies to determine extent of spread. Regional node dissections are often part of a correct cancer operation for cure, but also give staging information unobtainable by other methods. The surgeon must plan every procedure carefully with the aim of curing the patient and also deriving maximum information from the operation to enable correct planning of further treatment.

Between 1982 and 1986, 185 adult patients with non-Hodgkin's lymphoma (NHL) were studied at Cukurova University Hospital (CUH), Adana, Turkey. This constituted 13% of all malignant neoplasms diagnosed in the oncology clinic. The mean age for men was 45.5 years and 41 years for women. Fifty-four percent of the cases were nodal lymphoma and the remaining 46% were extranodal lymphoma. Sixty-six percent of the extranodal lymphoma cases were gastrointestinal lymphoma. The stomach was the most common localization (43%), followed by intestinal involvement (30%) and abdominal mass (27%). The mean age of the patients with gastric lymphoma was 49 years, and 36 years for patients with abdominal mass. The following conclusions were reached: (1) the relative frequency rate of NHL in South Turkey is higher than Turkey averages, but similar to other Middle East countries; (2) extranodal lymphomas account for more than 40% of all lymphomas; (3) gastric lymphoma is more prevalent than intestinal lymphoma in our region; and (4) compared with western gastric lymphomas, our patients were 10 years younger and had a higher incidence of small lymphocytic and immunoblastic lymphoma.

From 1966 through 1984, 142 patients with early stage non-Hodgkin's lymphoma of the head and neck were treated. Histologic slides were reviewed and reclassified according to Rappaport's classification and the Working Formulation. Patients were clinically staged; 82 Stage I, and 60 Stage II. Five-year freedom from relapse was 53% for Stage I and 48% for Stage II patients with no statistically significant difference. No patients with favorable histologies of Rappaport's classification or low grade malignancy of the Working Formulation relapsed. By univariate analyses, stage, primary site, the Working Formulation, Rappaport's classification, extent of radiation field, radiation dose, tumor bulkiness and addition of multiple-agent chemotherapy seemed to be prognostic factors for predicting relapse. Multivariate regression analyses (MVA) showed primary site and multiple-agent chemotherapy were independent prognostic factors. Tumor bulkiness provided marginal prognostic significance. Waldeyer's ring lymphomas fared better than nodal or extralymphatic lymphomas; it seems necessary to report Waldeyer's ring lymphomas independently from nodal or extralymphatic lymphomas. Patients receiving more than 3 chemotherapeutic agents had better prognosis than those receiving 3 or less agents, or no chemotherapy. Pathologic grade was another prognostic factor when the Working Formulation was used in MVA. When Rappaport's classification was used, division of unfavorable histologies into histiocytic and non-histiocytic groups provided only marginal significance in MVA. We conclude that Stage I-II non-Hodgkin's lymphomas of the head and neck with favorable histologies of Rappaport's classification or low grade malignancy of the Working Formulation be treated with radiation therapy only; and patients with other histologies should be treated with multiple-agent chemotherapy and radiation therapy.

Pairs of bone marrow trephine samples from 67 patients with known or suspected non-Hodgkin's lymphoma (NHL) were collected. One sample was processed for morphological examination, the other for frozen section immunohistology, using a panel of monoclonal antibodies (MAB) reacting with lymphocyte and macrophage determinants, detected by the immuno-alkaline-phosphatase (APAAP) method. Forty-one cases showed definite (36) or suspected (5) involvement of the marrow by NHL. Most were examples of lymphocytic or centroblastic/centrocytic NHL. The pattern of immunostaining confirmed the presence of NHL in these cases: the phenotype of the neoplastic cells was broadly consistent with nodal histology, where available. In ten cases, the marrow showed no evidence of involvement by NHL, and in 15, the eventual diagnosis was an abnormality of the myeloid series. These two groups of marrows not involved by NHL both showed a 'reactive' pattern of immunostaining, comprising polyclonal B-cells, T-helper and suppressor/cytotoxic cells and macrophages. We conclude that immunohistological examination of the bone marrow is useful in cases where the specimen shows morphological evidence of NHL, including those that are only 'suspect', but does not detect lymphoma where there is no morphological evidence of involvement.

Despite advances in the primary treatment of non-Hodgkin's lymphoma, relapse is common and treatment after relapse is unsatisfactory. Autologous bone marrow transplantation, although sometimes successful, has generally had disappointing results. We conducted a trial of such transplantation in patients with relapsed non-Hodgkin's lymphoma, using strict criteria in selecting patients; we included only those in whom disease was minimal after conventional treatment (nodal disease less than 2 cm and bone marrow involvement less than or equal to 5 percent on histologic examination) and whose tumor cells expressed the B1 antigen. Forty-nine patients meeting these criteria received cyclophosphamide and whole-body irradiation supported by transplantation of autologous bone marrow that had been treated in vitro with anti-B1 monoclonal antibody and complement. All patients had features of a poor prognosis, including relapse from primary chemotherapy, histologic conversion to more aggressive disease, and extra-nodal dissemination. Thirty-three patients had a history of bone marrow involvement--16 at the time that marrow was obtained. Hematologic and immunologic engraftment was achieved in all patients. Only two treatment-related deaths occurred, from venoocclusive disease of the liver and intracerebral hemorrhage, respectively. Disease-free remission without maintenance therapy has lasted from greater than 2 to greater than 52 months in 34 patients (median follow-up, greater than 11 months). These results are similar to those obtained in patients with advanced, high-grade non-Hodgkin's lymphoma treated with primary combination chemotherapy. This study demonstrates that autologous bone marrow transplantation has tolerable toxicity and high efficacy in a subset of patients who are otherwise incurable but still responsive to cytoreductive therapy. The results suggest a role for such transplantation in the treatment of selected patients with newly diagnosed non-Hodgkin's lymphoma.

Eight cases of primary non-Hodgkin's lymphoma of the breast found in the pathology files of the Institute of Oncology, Ljubljana, Yugoslavia, for a period of 25 years (from 1961 to 1985) were analyzed. During the same period 5711 cases of breast carcinoma were seen. Seven cases were diffuse lymphomas, and one case was nodular. Five cases were high-grade large cell lymphomas and three cases were of low-grade type. One case of the latter group was associated with elevated IgA in the serum and showed monoclonal reaction of plasmacytic lymphoma cells for kappa light chain and IgA. In this case amyloid deposits were seen in the breast tumor. In six cases, focal infiltration of ductal/lobular epithelium by lymphoma cells was found. This so-called lymphoepithelial lesion appears to be an important characteristic of various mucosa-associated lymphoid tissue lymphomas which have been described in different extranodal sites (e.g. gastrointestinal tract, and respiratory tract). They may show different behavior from nodal counterparts, especially in terms of their spread to other mucosal sites which may appear before or without nodal dissemination. The breast appears to be yet another location for these lymphomas.

Over the 27-year period from 1954-1981, 51 patients with non-Hodgkin's lymphoma arising in the tonsil were treated at the Regional Radiotherapy Centre, Mount Vernon Hospital. The original biopsy material was reviewed in each case and reclassified using the British National Lymphoma Investigation criteria. Grade 2 non-Hodgkin's lymphoma was reported in 80 per cent of cases. Ninety per cent of patients presented in stages IE or IIE and were treated with radical local radiotherapy. A 5-year survival of 51 per cent was achieved and a 5-year relapse-free survival of 35 per cent. Stage IE patients had a statistically significant survival advantage compared to stage IIE. Sixty-one per cent of patients relapsed, of whom 74 per cent died from active lymphoma. The abdomen was the most frequent site for relapse with involvement of both nodal and extranodal sites.
