Bienvenue sur le site du Groupe d’étude des Tumeurs Endocrines

Le groupe d'étude des tumeurs endocrines est une société savante créée en 2002 réunissant les différentes spécialités impliquées dans la prise en charge des tumeurs neuro-endocrines (TNE) : anatomopathologistes, biologistes, chirurgiens, endocrinologues, gastroentérologues, généticiens, médecins nucléaires, oncologues et radiologues.

Objectifs

Objectif principal : Compare the effect  of capecitabine (cape) + temozolomide (temo) and of 5FU + streptozotozin (strepto) given with a new schedule (LV5FU2 + strepto), two of the most used chemotherapy regimens in the treatment of well differentiated pancreatic neuroendocrine tumors alone or in combination with bevacizumab (beva) on progression-free survival (PFS) and compare the chemotherapy regimens alone or with beva (two by two design) on the same criteria.

Objectifs secondaires :
Compare the tolerance (NCI-CTC) and other parameters of efficacy of two different schedules of chemotherapy, and the effect on tolerance and efficacy of the addition of beva to chemotherapy:

Other parmaters of efficacy will include: objective response and its duration, quality of life (EORTC QLQC 30), and overall survival

Critères d'inclusion

2. Indication for chemotherapy for locally advanced or metastatic disease with proven progression (20% increase of tumor size on a 12 months period of follow-up) or other indication of chemotherapy following the TNCD (liver involvement > 50%, symptoms related to the tumour or its metastases, Ki67>10%)
