To determine the outcomes of patients with different pituitary disorders whether they are managed medically, surgically or expectantly.

Read the detailed description

A chart audit of around 1500 patients seen in two specific clinics, the Medical Pituitary Clinic and the combined Endocrine/Neurosurgical Pituitary Clinic at the University of Alberta Hospital, will be performed to determine the effectiveness of various treatment strategies on the long term outcome of specific pituitary disorders. The investigator's will collect retrospective demographic (age, sex, ethnicity), clinical (mode of presentation, hormonal parameters) and therapeutic outcome (surgical, medical, expectant and / or radiation treatment; co-morbidities and complications) of patients seen in these two clinics between January 2000 and December 2020.

Questions about this trial

What is this clinical trial studying?

An observational study of Pituitary Diseases and Pituitary Neoplasms, run by University of Alberta.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 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: under way, not looking for participants, as of the sponsor's last update on 16 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

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?

Progression free survival after pituitary surgery (time frame: up to 17 years post surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Mar 2026.
