Stereotactic Radiotherapy for Cerebral Metastases With Recent Hemorrhagic Signal (STEREO-HBM)

This is an interventional treatment trial for Hemorrhagic Brain Metastases focused on measuring hemorrhagic, brain metastases, FSRT, Stereotactic radiation therapy Read More

Inclusion Criteria:

• Age> 18 years
• Performance Status 0 or 1
• Patient with less than 4 brain metastases [of a solid tumor with a histologically proven diagnosis for the solid tumor; Patients who have had a metastasectomy and 1 to 3 brain metastatic lesions are eligible.
• Brain injury (s) measuring between 5 and 30 mm in diameter
• Patient eligible for stereotactic radiotherapy after a decision of the multidisciplinary committee

• Presence of intra-tumor bleeding signals on at least one brain injury before stereotactic irradiation and defined by :

  • hyperdense lesion on the non-injected CT (treatment scanner) and / or,
  • spontaneously hyperintense lesion on T1 MRI sequences without gadolinium injection and / or,
  • lesion with hypo signal on T2 sequences *

• Patient with controlled extra-cranial disease under systemic treatment (chemotherapy or targeted therapy):

  • illness in complete response
  • partial response or stable illness for more than 3 months
• Absence of meningeal tumor invasion
• Absence of brainstem metastasis

• Patient without concomitant anti-cancer therapy (chemotherapy, hormone therapy, immunotherapy, anti-angiogenic or other anti-cancer treatments). Treatments should be suspended for at least 7 days before the start of FSRT radiotherapy. The treatment can be resumed 7 days after the end of radiotherapy
• Patient cooperating sufficiently to perform the treatment with the use of a thermoformed mask
