Gastric MALT lymphoma in a population-based study in France: clinical features, treatments and survival.

Background: Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease, and most available data on gastric MALT lymphoma (GML) come from clinical studies of selected patients treated in centres of excellence.

Aims: To analyse the clinical features, management and survival of GML patients in a population-based study in France METHODS: All new cases of GML diagnosed between 2002 and 2010 in 11 French areas covered by cancer registries were included. Pathology reports were verified and, if necessary, reviewed by an expert pathologist.

Impact of Expert Pathologic Review of Lymphoma Diagnosis: Study of Patients From the French Lymphopath Network.

Purpose To prospectively assess the clinical impact of expert review of lymphoma diagnosis in France. Materials and Methods From January 2010 to December 2013, 42,145 samples from patients with newly diagnosed or suspected lymphomas were reviewed, according to the 2008 WHO classification, in real time by experts through the Lymphopath Network. Changes in diagnosis between referral and expert review were classified as major or minor according to their potential impact on patient care.

A Challenging Cutaneous T-Cell Lymphoma.

Cutaneous peripheral T-cell lymphomas not otherwise specified (CPTL-NOS) are rare neoplasms accounting for just 2% of cutaneous peripheral T-cell lymphomas (CPTL). Only very few case series have been reported. They represent a phenotypically and prognostically heterogenous group of CPTL that do not fit into any of CPTL well-defined subtypes.
