Observation Alone after Transsphenoidal Surgery for Nonfunctioning Pituitary Macroadenoma

Abstract

Transsphenoidal surgery without postoperative radiotherapy is an effective and safe treatment strategy for NFMA, without evidence for tumor regrowth in 90% of all patients, at least for the duration of follow-up presented in this study. Additional studies are required to exclude higher regrowth and recurrence rates during prolongation of the duration of follow-up.
