Last updated: September 21, 2010
Last verified: September 2010
Purpose of this study is to investigate whether intraoperative imaging using a 1.5T MRI in craniopharyngioma surgery is useful in order to increase the rate of complete tumor removal.

Condition Intervention
Craniopharyngioma Other: Intraoperative imaging using 1.5T MRI

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Intraoperative Use of a MR Tomography System Combined With Neuronavigation - Analysis of the Craniopharyngioma Subgroup ("Intraoperative Nutzung Eines Kernspintomographie-Systems in Direkter Kopplung Mit Einem Neuronavigations-System")

Further study details as provided by Hofmann, Bernd, M.D.:

Primary Outcome Measures:
  • Rate of additional tumor removal [ Time Frame: up to 3-4 months following surgery ]
    Number of patients in whom non suspected tumor remants were indicated by intraoperative MRI and remnants could be removed completely thereafter. Results have to be confirmed in 1st follow up imaging.

  • Rate of achievement of intended extent of removal [ Time Frame: up to three months following surgery ]
    It is examined whether the extent of tumor removal defined prior to surgery was achieved

  • Diagnostic reliability [ Time Frame: within 3 -4 months following surgery ]
    false positive or negative interpretation of intraoperative imaging determined after follow-up imaging 3 - 4 months following surgery

Secondary Outcome Measures:
  • Surgical complication [ Time Frame: within 1st week following surgery ]
    Rate of new deficits following surgery (excluding new endocrine deficits)

Enrollment: 25
Study Start Date: April 2002
