What this trial studies

This clinical trial investigates the use of 90Yttrium colloid as a treatment for cystic tumors located in the sellar and parasellar regions. The study aims to provide an alternative to traditional surgical and radiation therapies, which often come with significant risks and complications. Patients eligible for the trial will undergo standard surgical procedures as determined by the treating neurosurgeon, followed by the administration of the 90Yttrium colloid. The trial will monitor the effectiveness of this treatment in reducing tumor size and improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 17 and older with cystic sellar, suprasellar, or parasellar masses requiring surgical intervention.

Not a fit: Patients with solid tumors or those deemed by the neurosurgeon to have unacceptable surgical risks will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a safer and more effective option for patients with cystic sellar/parasellar tumors.

How similar studies have performed: While there is limited consensus on the best treatment for these tumors, previous cases of intracystic radiotherapy have shown promising results, suggesting potential success for this novel approach.
