Hippocampal-Avoiding Whole Brain Irradiation With Simultaneous Integrated Boost for Treatment of Brain Metastases

5 de enero de 2021 actualizado por: Robert Timmerman, University of Texas Southwestern Medical Center

Phase II Trial of Hippocampal-Avoiding Whole Brain Irradiation With Simultaneous Integrated Boost for Treatment of Brain Metastases

The investigators hypothesize that avoidance of the hippocampal region with WBRT (Whole-Brain Radiotherapy ) may delay or reduce the onset, frequency, and/or severity of NCF (neurocognitive function) decline, as measured with clinical neurocognitive tools.

Descripción detallada

We propose to use conformal avoidance of the hippocampal region during whole brain radiotherapy to reduce the dose to the hippocampi, thereby putatively limiting the radiation-induced inflammation of the hippocampal region and subsequent alteration of the microenvironment of the neural progenitor cells

Descripción

Inclusion Criteria:

  1. Pathologically (histologically or cytologically) proven diagnosis of a non-hematopoietic malignancy other than small cell lung cancer and germ cell malignancy..

Patients who have been disease free for more than 5 years prior to the appearance of CNS metastases should undergo repeat biopsy of either a systemic metastasis or the CNS metastases to confirm the recurrent malignancy.
  2. Patients with measurable brain metastasis outside a 5-mm margin around either hippocampus
  3. Patients with measurable brain metastasis who have not been or will not be treated with SRS (stereotactic radiosurgery ) or surgical resection (Note: These treatment options are only permitted at relapse)
  4. History/physical examination within 28 days prior to registration
  5. Patients must fall into RTOG (Radiation Therapy Oncology Group) recursive partitioning analysis (RPA) class I or II
  6. Patients must have a life expectancy of at least 4 months.
  7. Age ≥ 18 years
  8. Karnofsky performance status ≥ 70
  9. Patients must provide study-specific informed consent prior to study entry
  10. Women of childbearing potential and male participants must practice adequate contraception
  11. Women of childbearing potential must have a negative, qualitative serum pregnancy test ≤2 weeks prior to study entry

Exclusion Criteria:

  1. Patients with greater than 9 discrete metastases on MRI.
  2. Patients with leptomeningeal metastases
  3. Patients with measurable brain metastasis not resulting from small cell lung cancer and germ cell malignancy
  4. Plan for chemotherapy or targeted therapies during WBRT or over the subsequent 7 days
  5. Contraindication to MR (Magnetic resonance) imaging such as implanted metal devices or foreign bodies, severe claustrophobia AND patients unable to receive gadolinium contrast agents
  6. Serum creatinine > 1.4 mg/dl ≤ 28 days prior to study entry
  7. Prior radiation therapy to the brain
  8. Patients planning to undergo radiosurgery to any CNS lesion OR patients planning to have surgical resection of ALL of their CNS lesions

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Mean Change in *Delayed* Recall Score by Hopkins Verbal Learning Test-Revised (HVLT-R DR) Score
Periodo de tiempo: Baseline, 3 months

The HVLT-R is a validated test to assess neurocognitive function and it incorporates 6 different forms, each including 12 nouns (targets) with 4 words drawn from 3 semantic categories.

*Delayed*recall was measured by recalling the 12 targets after a 20-minute delay.

1 point is awarded for each successfully recalled target. There is no range- recalling more is more memory.

Mean change was calculated by the following formula: 100*(3 month - baseline) / baseline

Baseline, 3 months

*Immediate* recall was measured by memorizing a list of 12 targets for 3 consecutive trials.

1 point is awarded for each successfully recalled target. There is no range- recalling more is more memory.

*Delayed recognition* was measured by using recognition discrimination index.

1 point is awarded for each successfully recalled target. There is no range- recalling more is more memory.

Mean change was calculated by the following formula: 100*(3 month - baseline) / baseline

Baseline, 3 months
Mean Change in Neurocognitive Function as Measured by Controlled Word Association Test
Periodo de tiempo: Baseline, at 3 months

Controlled Word Association Test (COWAT) is used to assess language and executive/frontal skills. The patient produces as many words as possible in 1 min. (each) for a specific letter (C, F, L or P, R, W). Requires about 5 min to complete.

1 point is awarded for each word produced. Mean change was calculated by the following formula: 100*(3 month - baseline) / baseline

Baseline, at 3 months
Mean Change in Trail Making Test (TMT- A) Score
Periodo de tiempo: Baseline, at 3 months

Trail Making Test (TMT) is a measure of visuospatial scanning, attention, sequencing, and speed and executive function. Patients must "connect the dots" either in a numbered sequence or alternating letters and numbers.

The TMT has two parts that are referred to as the Trail Making Test Part A and the Trail Making Test Part B.

In Part A, the circles are numbered 1 - 25, and the patient should draw lines to connect the numbers in ascending order.

Possible score ranges from 0-3 minutes with higher score (more seconds/minutes) indicating significant cognitive impairment.

Mean change was calculated by the following formula: 100*(3 month - baseline) / baseline

Baseline, at 3 months
Mean Change in Trail Making Test (TMT- B) Score
Periodo de tiempo: Baseline, at 3 months

Trail Making Test (TMT) is a measure of visuospatial scanning, attention, sequencing, and speed and executive function. Patients must "connect the dots" either in a numbered sequence or alternating letters and numbers.

The TMT has two parts that are referred to as the Trail Making Test Part A and the Trail Making Test Part B.

In Part B, the circles include both numbers (1 - 13) and letters (A - L). Possible score ranges from 0-5 minutes with higher score (more seconds/minutes) indicating significant cognitive impairment.

Health-related Quality of Life as Assessed by the Functional Assessment of Cancer Therapy With Brain Subscale (FACT-BR)
Periodo de tiempo: 39 months

Quality of life will be assessed using the Functional Assessment of Cancer Therapy with Brain Subscale (FACT-BR). The FACT-BR is a multidimensional, self-report quality of life instrument specifically designed and validated for use with brain malignancy patients. It is written at the 4th grade reading level and can be completed in 5-10 minutes with little or no assistance in patients who are not neurologically incapacitated. It measures quality of life related to symptoms or problems across 5 scales: physical well-being (7 items); social/family well-being (7 items);emotional well-being (6 items); functional well-being (7 items); and concerns relevant to patients with brain tumors (23 items).

Items are rated on a 5-point scale (0-5): 0-"not at all", 1- "a little bit", 2-"somewhat", 3-"quite a bit" and 4-"very much", with HIGHER scores indicating a better quality of life.

39 months
Health-related Quality of Life as Assessed by Euroqol EQ-5D
Periodo de tiempo: 39 months

The EQ (Euroqol)-5D (5 Dimension) health related quality of life questionnaire is a standardized instrument for use as a measure of health outcome.

Applicable to a wide range of health conditions and treatments, it provides a simple descriptive profile and a single index value for health status. . The US version of the EQ-5D will be used, to enable mapping of general HR-QoL (Health-related quality of life) scores from EQ-5D scores into health state utility scores (ranging from 0 to 1) for the US population.

Possible scores range from 0 to 1, with HIGHER scores indicating a better quality of life.
