Whole-Brain Radiation Therapy With or Without Hippocampal Avoidance in Treating Patients With Limited Stage or Extensive Stage ...
Avoiding the hippocampus during whole-brain radiation could decrease the chance of side effects on memory and thinking.
a study on Lung Cancer
This randomized phase II/III trial studies how well whole-brain radiation therapy works and compares it with or without hippocampal avoidance in treating patients with small cell lung cancer that is found in one lung, the tissues between the lungs, and nearby lymph nodes only (limited stage) or has spread outside of the lung in which it began or to other parts of the body (extensive stage). Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. The hippocampus is part of the brain that is important for memory. Avoiding the hippocampus during whole-brain radiation could decrease the chance of side effects on memory and thinking. It is not yet known whether giving whole-brain radiation therapy is more effective with or without hippocampal avoidance in treating patients with small cell lung cancer.
Randomized Phase II/III Trial of Prophylactic Cranial Irradiation With or Without Hippocampal Avoidance for Small Cell Lung Cancer
- Determine whether the 12-month intracranial relapse rate following hippocampal avoidance (HA)-prophylactic cranial irradiation (PCI) is non-inferior compared to the rate following PCI for patients with small cell lung cancer (SCLC). (Randomized Phase II Component [Non-Inferiority]) II. Determine whether HA-PCI reduces the likelihood of 6-month deterioration from baseline in Hopkins Verbal Learning Test (HVLT)-Revised (R) delayed recall compared to PCI for patients with SCLC. (Phase III Component [Efficacy])
- Compare time to cognitive failure, as measured by a battery of tests (HVLT-R, Controlled Oral Word Association [COWA] test, and Trail Making Test [TMT] parts A and B), after PCI versus HA-PCI in SCLC.
II. Compare time to cognitive failure as separately measured by each test (HVLT-R for Total Recall and Delayed Recognition, COWA test, and TMT parts A and B), after PCI versus HA-PCI for SCLC.
III. Compare patient-reported cognitive functioning and other quality of life domains (assessed by the European Organization for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire [QLQ]-Core [C]30 and BN20) between PCI versus HA-PCI for patients with SCLC.
IV. Compare overall survival after PCI versus HA-PCI for patients with SCLC. V. Compare 12-month intracranial relapse rate (at completion of phase III) and time to intracranial relapse after PCI versus HA-PCI for patients with SCLC.
VI. Evaluate adverse events according to Common Terminology Criteria for Adverse Events (CTCAE) criteria.
VII. Correlate changes in health-related quality of life (HRQOL) domains with changes in cognitive testing outcomes following PCI versus HA-PCI for patients with SCLC.
VIII. Assess cost-effectiveness of HA-PCI (intensity modulated radiation therapy [IMRT]) and PCI (3-dimensional conformal radiation therapy [3DCRT]) using the EuroQual (EQ)-5-Dimensions (5D)-5L.
- Collect serum, whole blood, and urine for future translational research analyses.
II. Evaluate baseline magnetic resonance (MR) imaging biomarkers of white matter injury and hippocampal volumetry as potential predictors of cognitive decline and differential benefit from HAPCI as compared to PCI.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients undergo PCI using 3DCRT daily for 2 weeks.
ARM II: Patients undergo PCI with HA using IMRT daily for 2 weeks.
After completion of study treatment, patients are followed every 3 months for 1 year, then every 6 months until 3 years and then annually until death.

Open to people ages 18 years and up
- PRIOR TO STEP 1 REGISTRATION
- Histologic proof or unequivocal cytologic proof (fine needle aspiration, biopsy or two positive sputa) of SCLC within 250 days prior to Step 1 registration
- Patients must have a three-dimensional (3D), T1-weighted, spoiled gradient (SPGR), magnetization-prepared rapid gradient echo (MP-RAGE), or turbo field echo (TFE) MRI scan without and with gadolinium contrast-enhanced T1-weighted axial, coronal, and sagittal sequence acquisitions and standard T2-weighted axial and coronal fluid attenuation inversion recovery (FLAIR) sequence acquisitions within 28 days of Step 1 registration; to yield acceptable image quality, the pre-contrast-enhanced should have a resolution of 1 x 1 x 1.2 mm and should follow the protocols established by the Alzheimer's Disease Neuroimaging Initiative (ADNI); performance of this sequence at a 3 Tesla field strength is recommended; sites may contact the Imaging Co-Chair, Dr. Tammie Benzinger, for further information or assistance if needed; to yield acceptable image quality, the gadolinium contrast-enhanced T1-weighted scan should use the smallest possible axial slice thickness not exceeding 1.5 mm; the associated coronal and sagittal sequences can be up to 2.5 mm in slice thickness; this imaging is considered standard of care
- Note: The MRI study as part of response assessment following chemotherapy can be used for this purpose, but the appropriate sequences must be obtained; this sequence cannot be obtained prior to chemotherapy and is mandatory irrespective of randomization to the experimental or control arm of this study
- Patients must sign a study-specific informed consent prior to study entry
- PRIOR TO STEP 2 REGISTRATION
- The following baseline neurocognitive assessments must be completed within 14 days prior to Step 2 registration: HVLT-R, TMT, and COWA; the neurocognitive assessments will be uploaded into the National Surgical Adjuvant Breast and Bowel Project, Radiation Therapy Oncology Group, and Gynecologic Oncology Group (NRG) Oncology RAVE system for evaluation by Dr. Wefel; once the upload is complete, a notification will be sent to the site to proceed to Step 2; note: completed baseline neurocognitive assessments can be uploaded at the time of Step 1 registration
- Patients must have a baseline raw score greater than 2 on the HVLT-R delayed recall
- Prior to chemotherapy or thoracic radiotherapy, patients must be defined as limited-stage or extensive-stage SCLC after clinical staging evaluation involving the following:
- History/physical examination;
- Computed tomography (CT) of the chest and abdomen with contrast (does not have to be done if the patient has had a positron emission tomography (PET)/CT scan within 8 weeks prior to initiating chemotherapy or thoracic radiotherapy)
- MRI of the brain
- For patients without evidence of extensive-stage SCLC on chest and abdomen CT and brain MRI, a PET/CT or bone scan is required to confirm limited-stage SCLC
- Patients must be registered on study no earlier than 1 week and no later than 8 weeks after completing chemotherapy (+/- thoracic radiotherapy)
- After chemotherapy, patients must be restaged using the same diagnostic work-up as required pre-chemotherapy; repeat PET/CT or bone scan is not required; patients must have:
- No central nervous system (CNS) metastases
- Radiographic partial or complete response to chemotherapy in at least one disease site using Response Evaluation Criteria in Solid Tumors (RECIST) criteria
- No progression in any site
- Zubrod performance status 0-2
- Women of childbearing potential and male participants must practice adequate contraception
