Однофракционная стереотаксическая радиохирургия по сравнению с фракционированной стереотаксической радиохирургией для лечения интактного метастатического заболевания головного мозга, исследование FRACTIONATE
Фаза IIR испытаний однофракционной стереотаксической радиохирургии (SRS) по сравнению с фракционированной SRS (FSRS) при интактном метастатическом заболевании головного мозга (FRACTIONATE)
This phase II trial compares the effect of single fraction stereotactic radiosurgery to fractionated stereotactic radiosurgery for the treatment of patients with cancer that has spread to the brain (metastatic brain disease). Stereotactic radiosurgery (SRS) is a form of radiation therapy that focuses high-power energy on a small area of the body. This trial is being done to determine if single (one) fraction stereotactic radiosurgery is better than fractionated stereotactic radiosurgery or vice versa in controlling tumor and side effects in patients with tumors that have spread to the brain.

Подробное описание
PRIMARY OBJECTIVE:
I. To ascertain if the composite endpoint of cumulative treatment failure, defined by time to either local failure or symptomatic radiation brain necrosis of the largest brain metastasis (target lesion), is increased with fractionated stereotactic radiosurgery (FSRS) compared to single fraction stereotactic radiosurgery (SSRS).
SECONDARY OBJECTIVES:
I. To ascertain whether there is improved overall survival in patients who undergo FSRS compared to patients who receive SSRS.
II. To tabulate and descriptively compare the post-treatment adverse events associated with the interventions, including the potential impact of immunotherapy and targeted therapy.
III. To compare rates of radiation necrosis in patients who receive FSRS to patients who receive SSRS.
IV. To evaluate if there is any difference in central nervous system (CNS) failure patterns (e.g. local, distant brain failure) in patients who receive FSRS compared to patients who receive SSRS.
V. To ascertain whether FSRS prolongs time to neurologic death as compared to SRS.
VI. To determine whether there is improved patient reported outcomes (Functional Assessment of Cancer Therapy [FACT]-Brain Symptom Index [FBrSI]-24) including quality of life for patients who receive FSRS compared to patients who receive SSRS.
VII. To evaluate if there is any difference in CNS failure patterns (e.g. local, distant brain failure) and symptomatic radiation necrosis rates in patients who are treated with gamma knife compared to patients who are treated with a linear accelerator platform.
VIII. To determine whether differences in time to local failure, time to necrosis, or their composite endpoint cumulative treatment failure differs between treatment arms (or other patient or treatment factors) when analyzed on a "per lesion" basis rather than the per patient basis utilized for the primary endpoint.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients undergo single fraction SRS. Patients also undergo magnetic resonance imaging (MRI) at screening and during follow up.
ARM B: Patients undergo fractionated SRS, for 3-5 treatments, given over no more than 8 days. Patients also undergo MRI at screening and during follow up.
After completion of study treatment, patients are followed up at 3 months, every 3 months for 2 years, and then every 6 months for 3 years.

Inclusion Criteria:
-
Age >= 18 years old
-
Presence of presumed brain metastases from an extra-cerebral tumor site (e.g. lung, breast, prostate, etc.)
- Note: Dural based metastases (e.g. commonly seen in breast cancer) are eligible
-
Size of brain metastases
- At least one intact metastasis (not previously treated with radiosurgery) must measure >= 2.0 cm and =< 4.0 cm in maximal extent on the contrasted pre-treatment magnetic resonance imaging (MRI) brain scan obtained =< 28 days prior to registration
- If the largest lesion measures >= 2.0 to =< 4.0 cm in maximal extent the patient will be randomized
-
Able to undergo contrast enhanced MRI brain
-
Negative urine or serum pregnancy test completed =< 7 days prior to registration, for women of childbearing potential only
-
Patient is willing and able to provide written informed consent or have a legally Authorized Representative (LAR) who is responsible for the care and well-being of the potential study participant provide consent.
-
Karnofsky performance status (KPS) >= 50
-
Eastern Cooperative Oncology Group (ECOG) performance score of (PS) >= 2
-
Past radiosurgery or resection is allowed as long as no definitive evidence of progression in these locations
- Note: Repeat radiosurgery to the same location/lesion is not allowed on this protocol
Exclusion Criteria:
-
Any patient who has received previous whole brain radiation
-
Any brain metastasis that is located in the brainstem measuring >= 2.0 cm in maximal extent
-
Any patient with definitive evidence of leptomeningeal metastasis (LMD)
- NOTE: For the purposes of exclusion, LMD is a clinical diagnosis, defined as positive cerebrospinal fluid (CSF) cytology and/or unequivocal radiologic or clinical evidence of leptomeningeal involvement. Patients with leptomeningeal symptoms in the setting of leptomeningeal enhancement by imaging (MRI) would be considered to have LMD even in the absence of positive CSF cytology, unless a parenchymal lesion can adequately explain the neurologic symptoms and/or signs. In contrast, an asymptomatic or minimally symptomatic patient with mild or nonspecific leptomeningeal enhancement (MRI) would not be considered to have LMD. In that patient, CSF sampling is not required to formally exclude LMD, but can be performed at the investigator's discretion based on level of clinical suspicion
-
Any patient with an intact brain metastasis measuring > 4.0 cm
