About this study

Official title: Neoadjuvant Stereotactic Radiotherapy for Brain Metastasis - Prospective Trial NeoSTROBE

This multicentre proof-of-concept study, involving 4 centers, aims to establish the value of fractionated neoadjuvant stereotactic radiotherapy (NaSRT) as a new treatment paradigm for brain metastases (BM) in the frame of the Czech neurooncology network. Most relevant studies published to date used single-fraction radiotherapy and dealt with the inherent bias related to their retrospective nature. The researchers aim to increase the level of evidence for this treatment paradigm together with other similar ongoing studies.

Read the detailed description

The prospective study will evaluate the efficacy and toxicity of neoadjuvant stereotactic radiotherapy (NaSRT) in patients with brain metastases (BM). Clinical data gathered will include local control (LC), the incidence of leptomeningeal disease (LMD), radiological and clinical signs of radiation necrosis (RN), overall survival, and incidence of metachronous brain metastases. The magnetic resonance imaging (MRI) characteristics of irradiated and subsequently resected BM will be obtained according to the usual protocol and specified time intervals. Clinical monitoring will comprise neurological findings, Karnofsky performance status, and quality of life (FACT-Br/EORTC QLQ-C30 questionnaire and EORTC QLQ-BN20 questionnaire. These questionnaires are designed to measure cancer patients' physical, psychological, and social functions. The questionnaires are composed of multi-item scales and single items). The data obtained from the retrospective control group (estimated for 160 patients) will include the same parameters monitored in the consecutive group of patients who underwent surgery at centers included in our study, with or without adjuvant radiotherapy (RT). Formation of this control group corresponding to the NaSRT group will enable the efficacy and risks of NaSRT to be determined in comparison with established treatment modalities.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Neoadjuvant Stereotactic Radiotherapy (NaSRT)Radiation

    Neoadjuvant Stereotactic Radiotherapy (NaSRT) gives radiotherapy before surgery from many different angles around the body. The beams meet at the tumor. This means the tumor receives a high dose of radiation and the tissues around it receive a much lower dose. This lowers the risk of side effects.

  • Postoperative Stereotactic Radiotherapy (SRT)Radiation

    Postoperative Stereotactic Radiotherapy (SRT) gives radiotherapy after surgery from many different angles around the body. The beams meet at the tumor. This means the tumor receives a high dose of radiation and the tissues around it receive a much lower dose. This lowers the risk of side effects.
