    An analysis is presented of the histopathologic, clinical, and prognostic features in a series of 405 previously untreated patients with non-Hodgkin's lymphomas referred to Stanford University Medical Center between 1960 and 1971. All biopsies were histologically classified according to the criteria of Rappaport et al. and clinical extent of disease was thoroughly evaluated prior to treatment and staged according to the Ann Arbor Classification. Nodular lymphomas constituted 44% of the ...

    The pathologic findings in 84 untreated patients subjected to laparotomy and open iliac crest bone marrow biopsy for the staging of malignant lymphomas other than Hodgkin's disease at Stanford University Medical Center are presented. Fifty-one (61%) of these 84 patients had lymphomatous involvement of one or more sites below the diaphragm. The applicability of the histopathologic classification of Rappaport, Winter, and Hicks was confirmed by virtue of the constancy of the histologic ...

    We recently reported two cases of reversible Epstein-Barr virus (EBV)-associated lymphomas in patients undergoing methotrexate therapy for rheumatic disease. The current study was undertaken to investigate how frequently lymphoid neoplasms in patients with rheumatic disease show features of lymphoproliferations occurring in immunocompromised patients. Eighteen patients (including the two previously reported patients) with rheumatoid arthritis or dermatomyositis who developed ...

    Kikuchi's histiocytic necrotizing lymphadenitis is a self-limited disorder that typically involves the cervical lymph nodes of young women. Although a viral etiology has been postulated, a definitive viral agent has not been identified. Recent reports have suggested that human herpesvirus 8 (HHV 8) or Epstein-Barr virus (EBV) may play an etiologic role. We investigated the presence of HHV 8 and EBV in archival tissue from 34 cases of Kikuchi's histiocytic necrotizing lymphadenitis. We ...

    BACKGROUND: Epstein-Barr virus (EBV) positive Hodgkin disease (HD), as defined by the presence of EBV genes or gene products in the malignant cells, differs epidemiologically from EBV negative HD. However, survival patterns for EBV-defined HD have not been well studied. To determine if EBV status influenced survival time after HD, the authors investigated a large, population-based series of female patients.

    METHODS: For 311 female patients living in the Greater San Francisco Bay Area who ...

    BACKGROUND: Epidemiologic characteristics of human immunodeficiency virus (HIV)-related Hodgkin lymphoma (HL) have not been examined in the Greater San Francisco Bay Area, a center of the HIV/acquired immunodeficiency syndrome (AIDS) epidemic, for a decade, despite changes in AIDS-associated diseases after the availability of highly active antiretroviral therapies (HAART).

    METHODS: With population-based cancer registry data for 1988-1998, the authors examined risk factors, Epstein-Barr ...

    The gastrointestinal tract is the most common site for extranodal lymphomas, but follicular lymphomas involving the gut are rare. To study their pathologic features and bcl-2 expression, 31 follicular lymphomas of the GI tract were reviewed and unstained paraffin sections from 24 of the cases were immunohistochemically stained using a monoclonal antibody for the peptide product of the proto-oncogene bcl-2. The most common site of lymphoma involvement was the small intestine, especially ...

    The immunoreactivity of six different monoclonal antigranulocyte antibodies (Leu M1, TG1, 3C4, BY/87a, BY/37a, and 3CD1) has been evaluated in 23 cases of Hodgkin's disease (7 lymphocyte predominant, 12 nodular sclerosing, and 5 mixed cellularity); in a variety of non-Hodgkin's lymphomas and in a series of reactive and benign lesions of lymph nodes. Applying a monoclonal antibody (PD7/26) to leukocyte common antigen (T200), we have also investigated reports that the L&H variants in ...

    A study was made of 117 patients who presented with gastrointestinal lymphoma. The occurrence was 48 in the stomach, 37 in the small intestine, 13 in the ileocecal region, two in the appendix and 11 in the large intestine. In six cases, multiple sites in the gastrointestinal tract were involved, but in five cases this appeared to be secondary to massive mesenteric or retroperitoneal lymph node disease. Using Rappaport's classification, diffuse histiocytic lymphoma was the most frequent ...

    Natural killer (NK) and NK-like T-cell lymphomas are rare hematolymphoid malignancies that predominate in the upper aerodigestive system. They also involve other extranodal sites, including the skin. Primary cutaneous manifestations of NK and NK-like T-cell lymphomas are uncommon, and the clinicopathologic features are poorly understood. We have studied 12 patients of varied ethnic backgrounds with CD56-positive lymphomas in the skin. Six patients subsequently progressed to disseminated ...

    Although diffuse large cell lymphomas can be morphologically divided into large cell (DLC) and immunoblastic (IBL) subtypes, the clinical significance of this subdivision remains controversial. The initial diagnostic materials from 85 patients with recorded diagnoses of diffuse large cell lymphoma who were treated at Stanford between 1975 and 1986 with cyclophosphamide, doxorubicin (Adriamycin; Adria Laboratories, Columbus, OH), vincristine, and prednisone (CHOP); methotrexate, ...

    PURPOSE: Epstein-Barr virus (EBV) in Hodgkin's lymphoma (HL) cells has been considered as a prognostic marker for this heterogeneous disease, but studies have yielded mixed findings, likely because of selected patient series and failure to acknowledge an effect of age on outcome. This study assessed survival after HL in a population-based cohort large enough to examine the joint effects of EBV with other factors including age, sex, and histologic subtype.

    PATIENTS AND METHODS: Included ...
