Glucocorticoids, Immunotherapy and Radiosurgery for Brain Metastases

Background. Brain metastases are the most common intracranial tumor and occur in 20-40% of all oncological patients. The most common primary cancer in brain metastases is lung cancer, followed by melanoma, breast cancer, renal cancer and colorectal cancer. The incidence of brain metastases has been increasing but the occurrence of brain metastases is still associated with high morbidity and poor prognosis. The main treatment methods are stereotactic radiosurgery (SRS), microsurgical resection and whole brain irradiation (WBRT). The stereotactic Gamma Knife Radiosurgery (GKRS) is a non-invasive method, applying high dose radiation into an exact defined volume within the cranium, and thereby associated with significantly decreased neurotoxicity. It is the only treatment method for multiple disseminated and thereby non-resectable brain metastases. A novel treatment method of brain metastases is the combination of GKRS and systematic immunotherapy (IT), targeted therapy (TT) or chemotherapy, which showed significant improvements in survival. Furthermore, patients with brain metastases often develop cerebral edema, which is commonly treated with glucocorticoids to relieve the symptoms and decrease the fluid accumulation, but the long-term use was shown to be unfavorable due to various side effects. One of the potentially concerning side effect of glucocorticoids is the immunosuppressive properties. This raises the question of whether glucocorticoids might influence the effect of immunotherapy. Aim. The aim of the study is to evaluate if the use of glucocorticoids before, during and after treatment with gamma knife radiosurgery and immunotherapy effect the overall survival in patients with brain metastases, in contrast to patients undergoing gamma knife radiosurgery and immunotherapy alone. In addition, the effect of glucocorticoids on progression-free survival and clinical outcome will be evaluated. For the evaluation of the modern oncological treatment, patients with gamma knife radiosurgery, receiving immunotherapy, will be compared to patients not receiving immunotherapy. Patients and methods. The investigators plan to conduct a observational prospective preliminary study including about 200 radiosurgically treated patients with brain metastases. Patients will be included to our study, if they were diagnosed with one of two most common primary cancers (lung cancer or melanoma) and were treated with at least one Gamma Knife radiosurgical treatment for at least one brain metastasis. For the outcome evaluation of the different treatment options, a comprehensive database will be established. The study participations will not interfere with any clincally indicated therapeutic decisions and the study participants will not be exposed to any additional risks.

FLT-PET / MRI Brain Mets

Brain metastasis (BrM) develops in approximately 40% of cancer patients. Stereotactic radiosurgery (SRS) is a form of radiotherapy that delivers high-dose per fraction to individual lesions that is commonly used to treat BrM. Radionecrosis (RN) is an adverse event that occurs in approximately 10 - 25% of patients 6 - 24 months after treatment with SRS. Tumour progression may also occur due to local failure of treatment. Radionecrosis and tumour progression share very similar clinical features including vomiting, nausea, and focal neurologic findings. Radionecrosis and tumour progression also share overlapping imaging characteristics. Due to their similarities, physicians need to perform a surgical resection to diagnose the complication. By using a hybrid FLT-PET/MRI scan, the investigators propose that this combination scan will provide robust data with which to differentiate between radionecrosis and tumour progression without the need for surgery. The investigators plan to conduct a single center feasibility study to investigate the potential in differentiating between SRS and tumour progression in patients who have previously undergone SRS for BrM who are suspected to have either RN or tumour progression using hybrid FLT-PET/MRI imaging.

Role of Hyperpolarized 13C-Pyruvate MR Spectroscopy in Patients With Intracranial Metastasis Treated With (SRS)

Upwards of 40% of cancer patients will develop brain metastases during their illness, most of which become symptomatic. The burden of brain metastases impacts the quality and length of survival. Thus the management of brain metastases is a significant health care problem. Standard treatment options include stereotactic radiosurgery and/or whole brain radiation. There is a great interest in studying the association between the functional characteristics of tumors - such as tumour hypoxia and lactate accumulation - and clinical outcomes in order to guide management. These characteristics may predict future tumor behavior and stratify risk of therapy failure. Hyperpolarized 13C MR imaging is a novel functional imaging technique that uses 13C-labeled molecules, such as pyruvate, and MRS to image in vivo tissue metabolism. There is significant clinical heterogeneity in patients with brain metastasis due to differences in underlying tumour biology. Biochemical differences in tumour metabolism have been shown to correlate with response to therapy. While the significance of tissue hypoxia for radiosensitivity has been established for years, the impact of lactate accumulation on radiosensitivity has only recently been recognized. Studies have shown that tissue lactate levels correlate with radioresistance in several human tumours. Hyperpolarized 13C pyruvate MRS has been shown in numerous pre-clinical studies and a recent clinical study to have great potential as a metabolic imaging tool. Our study seeks to establish the role of hyperpolarized 13C MRS in characterizing the metabolic features of intracranial metastasis. The results of this study will provide insight into intracranial metastatic disease signatures with MR spectroscopy and determine if there is added benefit for incorporation of this new technique into future clinical MRI protocols. If the technique can accurately differentiate between aggressive and indolent tumours based on MR spectroscopic patterns, hyperpolarized 13C MRS may have wide-ranging utility in the future. In the era of personalized medicine, the ability of imaging tests to predict response to therapy would open the door for individualized treatment options specific to each patient's disease biology.

Pilot Phase 2 Study Whole Brain Radiation Therapy With Simultaneous Integrated Boost for Patients With Brain Metastases

This trial is a pilot, Phase 2, sequential two-cohort study designed to test two de-escalated whole brain radiation therapy (WBRT) dose levels and assess their ability to maintain acceptable in-brain distant control. The WBRT dose would decrease as the study moves forward, both in terms of absolute value and equivalent dose in 2 Gray fractions (EQD2) (as determined by the linear quadratic radiobiological model). The absolute value of the simultaneous integrated boost (SIB) dose will change with each dose level because the number of fractions delivered will depend on the WBRT dose. As such, the SIB dose will be manipulated such that the EQD2 will remain essentially equivalent despite the difference in the number of fractions delivered. This design will ensure that the only variable is the change in WBRT dose. The concept is that WBRT with SIB would be expected to maximize both local and in-brain distant control as has already been shown in studies exploring WBRT with SRS boost. However, by itself WBRT with SIB does not address the concern over neurocognitive outcomes. Therefore, investigators hypothesize that there is a lower WBRT dose threshold that will maintain acceptable in-brain distant control, particularly in the setting of a SIB to gross lesions to maintain treated lesion control. In addition, lower overall brain dose (including lower hippocampal dose without specific hippocampal avoidance) may potentially improve neurocognitive function. Investigators are also interested in evaluating treated lesion control, overall survival, neurocognitive sequelae of therapy, quality of life, performance status, and adverse effects of therapy. Biomarker identification for potential correlative circulating tumor DNA and microRNA is an exploratory endpoint to generate data for future prospective evaluation.

Neurocognitive Impact and Dose-Effect Relationship of Hippocampal Avoidance During Whole Brain Radiotherapy Plus Simultaneous Integrated Boost - A Prospective Follow-up Study

For newly-diagnosed patients with brain metastasis, whole brain radiation therapy (WBRT) probably remains a common palliative management even for those with oligometastatic brain disease. However, WBRT-related late sequelae, particularly a decline in neurocognitive functions (NCFs), are a major concern. More importantly, in patients with limited brain metastases and a fair/good performance status, sparing the radiosensitive and vulnerable structures which are responsible for essential NCFs during the WBRT course is one of the reasonable strategies to postpone and prevent the development of WBRT-induced neurocognitive impairments. Actually, radiation-related neurocognitive dysfunction is usually characterized as a decline involving learning and memory, in which the extremely radiosensitive hippocampus indeed plays a critical role. In addition to the neurocognitive preservation by virtue of sparing the radiosensitive structures like the hippocampus, durable intracranial tumor control critically depends on an escalated radiotherapeutic dose level which is adequate enough to eradicate gross metastatic brain lesions. Therefore, in order to achieve both hippocampal sparing and simultaneous integrated boost(s) to gross metastatic foci, a specialized WBRT technique, hippocampal avoidance during WBRT plus simultaneous integrated boost (SIB) will be adopted in this prospective study. Moreover, the dose-effect relationship would be analyzed in order to explore the correlation between the equivalent uniform dose (EUD) irradiating the hippocampus and the neurocognitive change/decline after the above WBRT course measured by objective neurocognitive test tools. Newly-diagnosed cancer patients harboring 1-3 gross metastatic lesions but still in fair/good performance statuses are potentially eligible. All recruited patients should receive baseline functional brain MRI examination and baseline neurobehavioral assessment. Treatment planning will be designed via the technique of volumetric-modulated arc therapy (VMAT) to achieve both hippocampal avoidance and simultaneous integrated boost(s) to gross metastatic lesions. Except for the above regions for which conformal avoidance or SIB is attempted, the prescribed dose to the remaining brain parenchyma will be consistently 3000 cGy in 12 fractions. Accordingly, a battery of neuropsychological measures, which includes 7 standardized neuropsychological tests (e.g., executive functions, verbal and non-verbal memory, working memory, and psychomotor speed), is used to evaluate neurobehavioral functions for our registered patients. The primary outcome measure is delayed recall, as determined by the change/decline in verbal memory or non-verbal memory, from the baseline assessment to 4 months after the start of the WBRT course. This prospective cohort study aims to examine thoroughly the impact of a specialized WBRT technique, integrating both simultaneous integrated boost(s) delivered to gross metastatic foci and conformal hippocampal avoidance, on the status of NCF change/decline in patients with oligometastatic brain disease. It is anticipated that intracranial local control will be more sustainable and durable resulting from the escalated focal dose of SIBs. Ultimately, we also expect the dose-effect relationship will be clearly demonstrated after investigating the correlation between the hippocampal dosimetry and the status of NCF change/decline after receiving HA-WBRT plus SIB.

A Prospective Study of the Impact of Hippocampal Avoidance During Whole Brain Radiotherapy on Neurocognitive Function Decline

Whole brain radiotherapy (WBRT) has long been a practical and effective therapeutic modality for various settings of management in radiation oncology. For example, the indications for WBRT should include brain metastasis or metastases, the setting of prophylactic cranial irradiation (PCI) used mainly for patients with limited-stage small cell lung cancer, and even some patients with extensive-stage small cell lung cancer. The rationales for WBRT are essentially based on that it can target both microscopic and gross intracranial disease. In addition to providing rapid alleviation of neurologic symptoms and enhanced intracranial disease control, WBRT might also prolong the time to develop neurocognitive function (NCF) decline. However, paradoxically NCF decline can also occur due to a sequel of WBRT. In terms of the time course of WBRT-induced NCF decline, it might vary considerably according to the specific domains which are selected to be measured. Early neurocognitive decline occurs within the first 1 - 4 months after WBRT for brain metastases. The domains of early neurocognitive decline principally involve verbal and short-term memory recall. Since several decades ago, it has been understood that hippocampus plays an essential role in memory function. Not little evidence supports that radiation-induced damage to hippocampus should be strongly associated with NCF impairment. Furthermore, several studies have shown that isodose distribution in hippocampus is closely related to neurocognitive function in patients with benign or low-grade brain tumors. As a consequence, it is hypothesized that conformal hippocampal sparing during the course of WBRT (HS-WBRT) might provide significant preservation in terms of cognitive function. This prospective cohort study aims to explore and evaluate the impact of the delivery of HS-WBRT on the pattern of NCF change and the extent of NCF decline in patients receiving prophylactic or therapeutic WBRT. As compared with previous related and relevant studies, it will also be investigated whether neurocognitive functional preservation can be achieved via the integration of hippocampal sparing with the course of WBRT.
