Memory Preservation of Hippocampal Avoidance Whole Brain Radiotherapy

The Memory Preservation Study of Whole Brain Radiotherapy With Hippocampal Avoidance for Patients With Brain Metastases

The study aimed to investigate the memory preservation and neurocognitive function protection of hippocampal avoidance whole brain radiotherapy (HA-WBRT) among people who speak Mandarin Chinese or Taiwanese.

Study Overview

Detailed Description

Brain metastasis is very common, about 30% incidence rate for all patients with a diagnosis of cancer. The rising incidence of brain metastasis is most likely due to recent advances in systemic therapy, and use of magnetic resonance imaging (MRI). The most common primary site is the lung followed by breast. One of the standard treatments is whole brain radiotherapy; it can prolong the decline of neurocognitive function and improve quality of life. However, it can also cause decline in neurocognitive function as a late sequela. Memory impairment is the main cognitive function that affected by radiotherapy, and the neuronal stem cells located at hippocampal subgranular zone are highly sensitive to radiotherapy. There have been large randomized trials confirming that by HA-WBRT, the neurocognitive function decline can be reclaimed. In Taiwan, HA-WBRT is a popular and emerging treatment. However, not much study focused on its effects on neurocognitive function. The study is aimed to objectively investigate the memory preservation and neurocognitive function protection of HA-WBRT in people speaking Mandarin Chinese or Taiwanese by utilizing neurocognitive function test and QoL questionnaire.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: HA-WBRT
Patients with brain metastases outside a 5-mm margin around either hippocampus and are eligible to this study will receive hippocampal avoidance whole brain radiotherapy 30 gray (Gy) in 10 fractions. The primary endpoint is Wechsler Memory Scale (Chinese) and cognitive abilities screening instrument (CASI) at 4 months.
Planning target volume(PTV) for whole brain is Whole brain parenchyma plus2mm margin excluding metastases and HA region, 30Gy in 10 fractions will be delivered to PTVwhole brain. Bilateral Hippocampus will be contoured according to Radiation Therapy Oncology Group 0933 and hippocampal avoidance region is Hippocampi + 5mm margin. According to Radiation Therapy Oncology Group 0933 trial, dose to 100% of the hippocampus could not exceed 9 Gy, and maximal hippocampal dose could not exceed 16 Gy; dose to 100% of the hippocampus exceeding 10 Gy
