Diagnosis of Primary Gastrointestinal Lymphomas and Mimics

Primary lymphomas of the gastrointestinal tract.

BACKGROUND A retrospective analysis of 12 years' experience (1987-1999), concerning gastro-intestinal lymphomas (LNH-GI) has been performed, to offer a contribution for the identification of the diagnostic and prognostic criteria. METHODS During this period, 11 cases (9 male and 2 female) have been treated: 8 with gastric localization and 3 with intestinal localization, with age ranging betwe...

Uptake Patterns of Untreated Primary Gastrointestinal Extranodal Lymphomas on Initial Staging 18F-FDG PET/CT and Metabolic Tumor Parameters

OBJECTIVE Non-Hodgkin's lymphomas arising from tissues other than primary lymphatic sites are classified as primary extranodal lymphomas (PEL). PELs of the gastrointestinal system (PGISL) originate from the lymphatic tissues within the gastrointestinal tract. The prognostic value of 18F-FDG PET/CT in lymphomas is high in terms of both overall survival (OS) and disease-free survival (DFS). Our a...

Histological and immunohistochemical studies on primary gastrointestinal lymphomas.

To study the characteristics and histogenesis of the malignant lymphomas derived from the gastrointestinal mucosa, histologic and immunohistochemical analyses were performed on a series of 28 malignant lymphomas of the gastrointestinal tract. By cytomorphologic classification, there were two small lymphocytic lymphomas, one small cleaved cell lymphoma, two mixed small cleaved and large cell lym...

Laparoscopic staging of gastrointestinal tumours.

management of those problems. Only with a complete knowledge of the staging of the disease can the appropriate treatment be applied, be it surgical or medical. Many of the approaches for this pre-operative (or “non operative”) staging are based in imaging exams that have shown, up till now, some degree of failure in its results. This is due to a lack of definition, both in dimensions and in his...
