Internationally, no clear guidelines have yet been developed for what we should do for patients in whom we find a gastric NET. Although mucosectomy is often advised for lesions of less than 1cm which have not metastasized, some groups advocate the use of surgical management. In addition, it is not clear how treated patients should be followed. Unanswered questions include whether scintigraphic imaging with Octreoescan should be used and whether endoscopies should be performed every 3 months or every 12 months.
No existe en el mundo una guía sobre qué hacer con los pacientes a quienes les encontramos un TNE gástrico; si bien se aconseja realizar mucosectomía a las lesiones menores de 1 cm en las que no existan metástasis, otros grupos aconsejan el manejo quirúrgico, pero no está claro cómo deben seguirse los pacientes ya tratados; si se debe realizar octreoescan o no, si se debe realizar EVDA cada 3 ó 12 meses, etc.
