About this study
Official title: Compare Between Endoscopic and Microsurgical Transsphenoidal Resection of Pituitary Adenomas With Intraoperative MRI
Prospective and randomized compare between microsurgical and endoscopic transsphenoidal MRI assisted resection of pituitary adenomas.
Read the detailed description
The main aim of the study is to compare microsurgical and endoscopic transsphenoidal surgery and to determine endocrine outcome. Secondary extent of resection and quality of life will be evaluated.
- Conditions
- Pituitary Adenoma
- Being tested
- Endoscopic resection, Microsurgical resection
- Medical subject headings
- Pituitary Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Endoscopic resectionProcedure or surgery
Transsphenoidal endoscopic resection of pituitary adenoma
Microsurgical resectionProcedure or surgery
Transsphenoidal microsurgical resection of pituitary adenoma
| Study group | Role | What they receive |
|---|---|---|
| microsurgical technique | Active comparator | Not described Receives: Procedure: Microsurgical resection |
| endoscopic technique | Active comparator | Not described Receives: Procedure: Endoscopic resection |
What is being measured
The primary outcome is the main question the study is designed to answer.
endocrine function
Testing of pituitary function with insulin-hypoglycemic test, results will be dichotomized as satisfactory or not satisfactory. Satisfactory outcome is defined, if pituitary function improves or is stable, if compared to preoperative testing.
Measured: 1 year after surgery
Secondary outcomes (2)
Extent of resection
Volumetric analysis of tumor volume before the surgery, intraoperatively and 3 months after surgery will be performed. Gross total resection is defined as no tumor present in gadolinium enhanced T1 sequences
Measured: tumor volume before the surgery, 3 months after surgery
Quality of Life, EQ-5D
EQ-5D will be evaluated before surgery, after the surgery in 3 months and after 1 year.
Measured: 3 months and 1 year after surgery

Primary outcome
endocrine function
Time frame: 1 year after surgery
Testing of pituitary function with insulin-hypoglycemic test, results will be dichotomized as satisfactory or not satisfactory. Satisfactory outcome is defined, if pituitary function improves or is stable, if compared to preoperative testing.
2 secondary outcomes
Extent of resection
Time frame: tumor volume before the surgery, 3 months after surgery
Quality of Life, EQ-5D
Time frame: 3 months and 1 year after surgery
Results and safety
The study was stopped early (reason given: Inadequate recruiting). Results are not available in the source record.

Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 17 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Inadequate recruiting). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
endocrine function (time frame: 1 year after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03515603, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 May 2023; AzTrials last refreshed its copy on 7 Nov 2026.
