NCT04516070

Brief Summary

This phase II trial investigates how stereotactic radiosurgery affects brain functions while treating patients with small cell lung cancer that has spread to the brain (brain metastasis). Standard of care treatment consists of whole brain radiation therapy, which targets the entire brain, and may result in side effects affecting the nervous system. Stereotactic radiosurgery only targets areas of the brain that are suspected to be affected by the disease. The purpose of this trial is to learn if and how patients' brain functions are affected by the use of stereotactic radiosurgery rather than whole brain radiation therapy in managing brain metastasis caused by small cell lung cancer. Stereotactic radiosurgery may help patients avoid nervous system side effects caused by whole brain radiation therapy.

Outcome Measures

Primary Outcomes (2)

  • Cognitive decline

    Will be defined as a decline of \>= 1 standard deviation from baseline on at least 1 of the 5 cognitive tests. Will be estimated along with the 95% confidence interval. For patients with or without prior radiation therapy to the central nervous system, the cognitive decline rate will also be estimated respectively. Fisher exact test will be used to compare the neurocognitive decline rate at 3 month post-SRS in subgroups (e.g. prior therapy difference).

    At 3 months post-stereotactic radiosurgery (SRS)

  • Incidence of adverse events

    All toxicities will be assessed with National Cancer Institute predefined Common Terminology Criteria for Adverse Events version 5.

    Up to 36 months

Secondary Outcomes (13)

  • Cognitive decline

    Up to 36 months

  • Change in neurocognitive score

    Baseline, up to 36 months

  • Overall survival

    Time from SRS until death or last follow-up, assessed up to 36 months

  • Small cell lung cancer (SCLC)-specific survival

    Time from SRS till SCLC-related death or last follow-up, assessed up to 36 months

  • Time to neurocognitive decline

    Time from date of SRS till the cognitive decline, assessed up to 36 months

  • +8 more secondary outcomes

Study Arms (1)

Treatment (SRS)

EXPERIMENTAL

Patients undergo SRS in the absence of disease progression or unacceptable toxicity. Patients whose disease progresses may be treated with additional courses of SRS per physician discretion.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must have Eastern Cooperative Oncology Group (ECOG) =\< 3
  • All patients must have histologic evidence suggesting small cell lung cancer. Histologic confirmation may be from the primary tumor site, or from another metastatic site (systemic lymph node, etc.). Cytology-alone is not an acceptable method of diagnosis.
  • Patient has 10 or less brain metastases on contrast-enhanced brain MRI scan obtained no greater than 6 weeks prior to study registration. Biopsy of brain metastasis is not required. A patient may be enrolled with zero brain metastasis assuming that the SRS is to be directed at the post-operative surgical cavity of a resected metastasis.
  • Patients must be eligible to have all lesions treated with stereotactic radiosurgery as determined by the study radiation oncologist
  • Patients must sign informed consent indicating that they are aware of the investigational nature of this study in keeping with the policies of the hospital
  • Patients should have normal coagulation \[International Normalized Ratio (INR) \< 1.3\]. within 28 days of enrollment.
  • Patient's primary language is English
  • No prior radiation therapy to the brain, including WBRT, PCI, or SRS
  • Performance Status Assessment
  • Standard ECOG performance status assessment will be used and determined by the treating physician

You may not qualify if:

  • Patients are excluded if they have a history of metastatic cancer in addition to small cell malignancy or a history of uncontrolled non-metastatic cancer. Patients with localized squamous cell carcinoma and/or basal cell carcinoma are not excluded
  • Patients are excluded if there is radiographic evidence of leptomeningeal disease
  • Patients are excluded if there are malignant cells identified in the CSF on cytologic examination
  • Patients are not excluded for circulating tumor deoxyribonucleic acid (DNA) (ctDNA) found in the CSF
  • Female patients of childbearing age are excluded if they are pregnant as determined with a urine or serum beta human chorionic gonadotropin (HCG) no greater than 14 days prior to study registration, or breast-feeding
  • Patients are excluded if they are unable to obtain an MRI scan for any other reason, including gadolinium allergy
  • Patients are excluded with medical history of a psychiatric or neurologic illness, or other comorbidities believed to affect cognitive function. Subjects with neurocognitive deficit related to brain metastasis are an exception to this criterion and may qualify for the study.
