The foregoing suggests that tumors smaller than 1 cm are usually benign. Tumors between 1cm and 2 cm which appear with chronic atrophic gastritis or with MEN-1 and/or Zollinger Ellison syndrome and hypergastrinemia, whether the tumors are single or multiple, are difficult to predict but generally well located. Tumors bigger than 2 cm are malignant and frequently develop metastases.
Lo anterior sugiere que los tumores menores a un cm tienen un curso benigno, los de 1 a 2 cm únicos o múltiples con GCA o AEM-1/ZE e hipergastrinemia son difíciles de predecir pero en general se encuentran bien localizados, mientras que los mayores de 2 cm son malignos y frecuentemente desarrollan metástasis.
