The role of surgery in the treatment of gastrointestinal lymphomas other than low-grade MALT lymphomas.
BACKGROUND AND OBJECTIVE A bias in clinical investigations on gastrointestinal lymphomas is the lack of testing the intention to treat as to resection, emergency conditions at presentation and selection brought about by the evaluation of feasibility of surgery. DESIGN AND METHODS A prospective study involved 154 patients with gastrointestinal nodular or high-grade MALT lymphomas, 111 with a g...
متن کاملNon-MALT marginal zone lymphomas.
The concept of marginal zone B-cell lymphomas was developed in the 1990s for lymphomas whose cells originate from B lymphocytes normally present in a distinct anatomical location, the so-called ‘marginal zone’ (MZ). MZ has been described in the lymphoid organs—spleen and lymph nodes—and in nonlymphoid organs—mucosa-associated lymphoid tissue (MALT) or non-mucosal tissue such as skin, orbit and ...
متن کاملThe management of nongastric MALT lymphomas.
The group of marginal zone B-cell lymphomas (MZL) comprises three different entities, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (currently called MALT lymphoma), nodal marginal zone B-cell lymphoma (previously known as monocytoid lymphoma), and splenic marginal zone B-cell lymphoma (with or without circulating villous lymphocytes).[1-3] Primary splenic and no...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولBRAF mutation status in gastrointestinal stromal tumors.
Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors characterized by mutations of KIT or PDGFRA. The objectives of this study were to evaluate BRAF mutations in GISTs and then to correlate BRAF mutational status in the tumor with clinical parameters, with B-raf expression, and with activation of some cellular pathways. BRAF mutation was screened in 321 GISTs with 70 wild-type GISTs. ...
