IELSG -26

Trial Name

IELSG-26 - A Clinico-pathologic study of primary mediastinal B-cell lymphoma.

Description

This prospective multi-centre cohort study has been designed to investigate the diagnostic and prognostic utility of PET scan in primary mediastinal lymphoma.

Objectives

Aims of the study was the determination of response rate on PET scanning following initial chemo-immunotherapy and a systematic analysis of the phenotype and molecular characteristics of Primary Mediastinal Large B-cell Lymphoma.

Design

Patients were enrolled on the basis of the clinical and pathologic characteristics of their lymphoma. Central review of all pathology carried out, with storage of fresh frozen biopsy material wherever possible. PET scans performed at the start of chemotherapy and at its conclusion, with central review of the images for quality control. Interim (mid-treatment) PET scans permitted according to normal practice in each centre, but was not reviewed centrally. Patients received one of the standard chemo-immunotherapy protocols currently in use for diffuse large B-cell lymphoma (i.e., R-CHOP-21, R-CHOP-14,R-MACOP-B, R-VACOP-B, R-ACVBP). Consolidation radiotherapy to the mediastinum has been carried out according to the local protocol of the treating centre.

Status

Complete

Population

120 patients across 5 countries, who are scheduled to receive R-chemotherapy for Primary Mediastinal B-cell lymphoma.
