Hippocampal avoidance whole-brain radiotherapy with simultaneous integrated boost in lung cancer brain metastases and utility of the Hopkins verbal learning test for testing cognitive impairment in Chinese patients: a prospective phase II study

Study Title: Hippocampal Avoidance Whole-Brain Radiotherapy for Lung Cancer Brain Metastases

Summary

This study evaluated the effectiveness of a specific radiotherapy technique and cognitive testing in Chinese lung cancer patients with brain metastases. The results showed promising outcomes in terms of survival and cognitive function.

Key Findings

– The median survival for all patients was 14.8 months, with a progression-free survival of 6.7 months.
– Male sex and newly diagnosed stage IV disease were associated with poorer survival outcomes.
– The Hopkins Verbal Learning Test-Revised (HVLT-R) scores showed a decrease of approximately 9.8% at 6 months after radiotherapy compared to baseline.
– No severe side effects were observed in the patient group.

Conclusion

The study concluded that Hippocampal Avoidance Whole-Brain Radiotherapy with a Simultaneous Integrated Boost (HA-WBRT-SIB) is effective and preserves cognitive function in treating Chinese lung cancer brain metastases.
