Evaluating neurobehavioral functions in newly diagnosed primary CNS lymphoma patients receiving advanced radiation therapy

Prospective Neurobehavioral Evaluation in Newly-diagnosed Patients With Primary CNS Lymphoma Treated With Hyperfractionated Conformal Whole-brain Radiation Therapy Plus Simultaneous Integrated Boost

Chang Gung Memorial Hospital · NCT04006561

This study is testing a new radiation therapy for people newly diagnosed with primary CNS lymphoma to see if it can control the tumor while also helping to protect their thinking and memory skills.

What this trial studies

This observational study focuses on patients newly diagnosed with primary central nervous system lymphoma (PCNSL) who will receive hyperfractionated conformal whole-brain radiation therapy combined with a simultaneous integrated boost. The aim is to achieve effective tumor control while minimizing neurocognitive decline, a common side effect of traditional treatments. Patients will undergo a thorough neurobehavioral and neurocognitive assessment to evaluate the impact of this treatment approach. The study seeks to provide insights into the balance between effective cancer treatment and the preservation of cognitive functions.

Who should consider this trial

Good fit: Ideal candidates include individuals with a confirmed diagnosis of non-Hodgkin's lymphoma in the brain who meet specific health criteria.

Not a fit: Patients with a history of major psychiatric disease or prior cranial irradiation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved survival rates and better quality of life for patients by reducing neurocognitive side effects associated with treatment.

How similar studies have performed: While there have been studies on conventional treatments for PCNSL, this specific approach of hyperfractionated conformal WBRT with SIB is relatively novel and has not been extensively tested.
