NCT Number: NCT02635009
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.

PRIMARY OBJECTIVES:
I. 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])
SECONDARY OBJECTIVES:
I. 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.
IX. Correlate miRNA signatures with cognitive failure in SCLC patients who received PCI and HA-PCI.
X. Evaluate Apolipoprotein E (APOE) genotyping as potential predictor of neurocognitive decline, hippocampal atrophy after brain irradiation and/or differential benefit from hippocampal avoidance.
XI. Evaluate baseline MR imaging biomarkers of white matter injury and hippocampal volumetry as potential predictors of cognitive decline and differential benefit from HA-PCI as compared to PCI.
TERTIARY OBJECTIVES:
I. 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 HA-PCI as compared to PCI.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.

Time frame: Baseline and six months
The HVLT-R delayed recall test assesses verbal learning and memory. The test involves memorizing a list of 12 nouns for 3 consecutive trials to recall after a 20-minute delay. The score is the sum of the number of words correctly recalled and ranges from 0 to 36, with a higher score indicating better functioning. Deterioration is defined a decrease from baseline of at least 3 points.
Time frame: From baseline to 12 months
Intracranial relapse, defined as the development of a new brain metastasis as documented on brain MRI with contrast or head CT with contrast.
Time frame: Randomization to date of failure, death, or last known follow-up whichever occurred first. Maximum follow-up at time of analysis was 7.2 years.
Neurocognitive failure is defined as the first instance of neurocognitive decline in any of six assessments, as determined my reliable change index: Hopkins Verbal Learning Test-Revised (HVLT-R) Total Recall, HVLT-R Delayed Recall, HVLT-R Delayed Recognition, Trail Making Test (TMT) part A, TMT part B, and Controlled Oral Word Association (COWA). Failure time is defined as time from randomization to failure, death (competing event), or last follow-up (censored). Neurocognitive failure rates are estimated using the cumulative incidence method. The distributions of failure times are compared, which is reported in the statistical analysis results. Six-month rates are reported here. Analysis occurred after all patients had been on study for at least six months.
Time frame: Baseline, 3, 6, 12 months.

The TMT is a neuropsychological test of visual attention and task switching that can provide information about visual search speed, scanning, speed of processing, mental flexibility, and executive functioning. Subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. There are two parts to the test: in the first (Part A, reported here), the targets are all numbers (1, 2, 3, etc.) and the test taker needs to connect them in sequential order. The score is the amount of time, in seconds, that it takes the patient to complete the maze. The range for Part A is 0 to 180 (3 minutes). Lower scores indicate better functioning. Deterioration is defined an increase from baseline of at least 12 seconds.

The COWA is a verbal fluency test that measures spontaneous production of words belonging to the same category or beginning with some designated letter. Patients are given 1 minute to name as many words as possible beginning with the designated letter. The procedure is then repeated for the remaining two letters. Two alternate forms of the COWA are employed to minimize practice effects. The score is the sum of the correct responses with a range of 0 to infinity. A higher score indicates better functioning. Deterioration is defined an increase from baseline of at least 12 words.

The Pearson correlation coefficient was calculated for EORTC QLQ-C30 (physical, role, emotional, cognitive, and social functioning domains and global health status) and QLQ-BN20 (motor dysfunction and communication deficit) versus the standardized neurocognitive function (HVLT-R total recall, HVLT-R delayed recall, HVLT-R delayed recognition, COWA, TMT parts A and B) and the Clinical Trial Battery Composite (CTB Comp) score (mean of the z-scores for the six NCF scores) for all patients, treatment arms combined. The Pearson correlation coefficient is computed for each pair of measurements, resulting in 48 correlation coefficients. Possible values range from -1 (negatively correlated) to 1(positively correlated), with 0 indicating no correlation. A correlation with a value in range -0.35 to 0.35 is considered weak and is indicated by "0" in the table. Because of the large number of comparisons, only individual correlation coefficients outside that range are listed here.
Time frame: Baseline to two years
The incremental cost per quality-adjusted life year (QALY) ratio will be calculated as total cost of the PCI with HA using IMRT arm (Arm 2) minus total cost of the PCI using 3DCRT arm (Arm 1), divided by the quality adjusted survival of the Arm 1 patients minus the quality adjusted survival of Arm 2 patients.
Time frame: From the date of randomization to the date of death or last follow-up. Maximum follow-up time at time of analysis was 7.2 years.
Overall survival time is defined as time from randomization to the date of death from any cause or last known follow-up (censored). Overall survival rates are estimated by the Kaplan-Meier method. Analysis occurred after all patients had been on study for at least 8 months.
Time frame: From date of randomization to date of intracranial relapse, death, or last known follow-up, whichever occurred first. Maximum follow-up at time of analysis was 7.2 years.
Intracranial relapse is defined as the development of a new brain metastasis as documented on brain MRI with contrast or head CT with contrast. Time to intracranial relapse is defined as time from randomization to the date of first intracranial relapse, last known follow-up (censored), or death without intracranial relapse (competing risk), whichever occurred first. Intracranial relapse rates are estimated using the cumulative incidence method. The distributions of intracranial relapse times are compared between the arms, which is reported in the statistical analysis results. One-year rates are provided here. Analysis occurred at time of the phase III primary analysis.
Time frame: Baseline to 6 months
Pearson correlation coefficients will be used to assess the effect of hippocampal volume and FLAIR volume change on baseline neurocognitive function, as measured by the HVLT-R, COWA, and TMT, separately for each arm.
