Brief Summary:
This phase III trial studies magnetic resonance imaging (MRI) surveillance and prophylactic cranial irradiation (PCI) to see how well they work compared to MRI surveillance alone in treating patients with small cell lung cancer. MRI scans are used to monitor the possible spread of the cancer with an MRI machine over time. PCI is radiation therapy that is delivered to the brain in hopes of preventing spread of cancer into the brain. The use of brain MRI alone may reduce side effects of receiving PCI and prolong patients' lifespan. Monitoring with MRI scans alone (delaying radiation until the actual spread of the cancer) may be at least as good as the combination of PCI with MRI scans.

Extensive Stage Lung Small Cell Carcinoma Limited Stage Lung Small Cell Carcinoma Lung Small Cell Carcinoma Procedure: Magnetic Resonance Imaging Radiation: Prophylactic Cranial Irradiation Phase 3

Detailed Description:

PRIMARY OBJECTIVE:

I. To evaluate whether overall survival (OS) with magnetic resonance imaging (MRI) surveillance alone is not inferior to MRI surveillance combined with prophylactic cranial irradiation (PCI) for the treatment of small cell lung cancer (SCLC).

SECONDARY OBJECTIVES:

I. To compare cognitive failure free survival (CFFS) rate up to 12 months after randomization between the arms.

II. To compare brain-metastasis-free survival between the arms. III. To compare OS between the arms within the subgroups of patients with limited-stage and extensive-stage disease.

IV. To compare cognitive failure free survival (CFFS) rates at the assessment times between the arms.

V. To compare the cumulative incidence of cognitive failure with death as a competing risk between the arms.

VI. To compare the frequency and severity of toxicities between the two arms.

ADDITIONAL OBJECTIVE:

I. To collect blood for banking.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients undergo conventional or hippocampal avoidance PCI over 20 minutes 5 days per week for 2 weeks. Patients also undergo MRI scan at 3, 6, 9, 12, 18, and 24 months.

ARM II: Patients undergo MRI scan at 3, 6, 9, 12, 18, and 24 months.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Overall survival (OS) [ Time Frame: From the date of registration to date of death due to any cause, assessed up to 2 years after randomization ]
    Will evaluate OS with magnetic resonance imaging (MRI) surveillance alone and MRI surveillance combined with prophylactic cranial irradiation (PCI) for the treatment of small cell lung cancer (SCLC).


Secondary Outcome Measures :
  1. Cognitive failure-free survival (CFFS) [ Time Frame: Baseline to first neurocognitive failure CF or death due to any cause, assessed up to 12 months after randomization ]
    The comparison of CFFS up to 12 months between the arms will be done using a 1-sided 5% level log-rank test.

  2. CFFS rate [ Time Frame: Baseline to first neurocognitive failure CF or death due to any cause, assessed at 90, 180, 270, 360, 540, and 720 days after randomization ]
    There will be a comparison of the CFFS rates between the arms at each of the assessment times and the cumulative incidence of cognitive failure, evaluating death as a competing risk. The CFFS rates at the landmark times will be estimated using the method of Kaplan-Meier and the difference in rates will be evaluated using a 90% confidence interval using Greenwood?s formula.

  3. Cumulative incidence of cognitive failure [ Time Frame: Neurocognitive function test will be assessed at 90, 180, 270, 360, 540, and 720 days after randomization ]
    The cumulative incidence of cognitive failure in the presence of the competing risk of death will be estimated used the method of Fine and Gray.

  4. OS in an "as-treated" analysis [ Time Frame: From the date of registration to date of death due to any cause, assessed up to 2 years after randomization. Patients will be seen at day 90, 180, 270, 360, 540, and 720 ]
    The comparison of OS in the ?as-treated? analysis will be done as described for the primary analysis, however patients will be categorized per treatment received (patients who do not accept their randomized assignment will be analyzed per treatment received). The number of patients not accepting the randomized assignment will also be summarized.

  5. Brain metastases-free survival (BMFS) [ Time Frame: Up to 2 years after randomization. Patients will have MRI on day 90, 180, 270, 360, 540, and 720 ]
    This will be estimated using the method of Kaplan-Meier and comparisons will be done using a log-rank test at the 1-sided 0.05 level. Hazard ratios and associated confidence intervals will be estimated using a Cox Proportional hazards model. Confidence intervals for medians will be estimated using the method of Brookmeyer-Crowley.

  6. Incidence of adverse events [ Time Frame: Up to 2 years after randomization. Patients will be assessed for adverse event after PCI (for patients on PCI + MRI arm) and at month 3 (all patients) ]
    Binary proportions and associated confidence intervals will be estimated.

  • No more than 8 weeks may have elapsed between day 1 of the last cycle of chemotherapy and randomization
  • Patient must not have received prior radiotherapy to the brain or whole brain radiotherapy. Patients who have undergone prior stereotactic radiosurgery for benign tumors or conditions (e.g., acoustic neuroma, grade I meningioma, trigeminal neuralgia) may be considered on a case-by-case basis
  • Patient must have Zubrod performance status of 0-2
  • Patient must not have a contraindication to MR imaging, such as implanted metal devices or foreign bodies
  • Patient must not have a contraindication to gadolinium contrast administration during MR imaging, such as allergy or insufficient renal function
  • Patient must not have other metastatic malignancies requiring current active treatment

  • Patient must not have any severe active comorbidities, defined as follows:

    • Unstable angina and/or congestive heart failure requiring hospitalization within 6 months prior to randomization
    • Transmural myocardial infarction within 6 months prior to randomization
    • Acute bacterial or fungal infection requiring intravenous antibiotics at the time of randomization
    • Chronic obstructive pulmonary disease exacerbation or other acute respiratory illness precluding study therapy at the time of randomization
    • Severe hepatic disease defined as a diagnosis of Child-Pugh class B or C hepatic disease

    • Human immunodeficiency virus (HIV) positive with CD4 count < 200 cells/microliter

      • Note that patients who are HIV positive are eligible, provided they are under treatment with highly active antiretroviral therapy (HAART) and have a CD4 count >= 200 cells/microliter within 16 weeks prior to randomization
      • Note also that HIV testing is not required for eligibility for this protocol

In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation. However, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures
