简要总结
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving temozolomide together with radiation therapy may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving temozolomide together with radiation therapy works in treating patients with low-grade gliomas.
详细描述
OBJECTIVES:
- Compare the 3-year survival of patients with high-risk low-grade gliomas treated with temozolomide and radiotherapy followed by temozolomide alone with that of patients enrolled on European Organization for Research and Treatment of Cancer (EORTC)clinical trials EORTC-22844 and EORTC-22845.
- Determine the toxicity of this regimen in these patients.
- Determine the association between progression-free survival and O6-methylguanine-DNA methyltransferase (MGMT) methylation status in patients treated with this regimen.
- Determine the association between survival and MGMT methylation status in patients treated with this regimen.
- Determine the quality of life (QOL) of patients treated with this regimen.
- Determine the neurocognitive function of patients treated with this regimen.
- Evaluate the feasibility of collecting patient-reported QOL and neurocognitive assessments over 3 years.
OUTLINE: This is a non-randomized, multicenter study.
Patients receive oral temozolomide once daily on days 1-42 and undergo radiotherapy once daily on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-40, one hour before RT weekdays, in the evening weekends. Beginning 28 days after completion of chemoradiotherapy, patients receive oral temozolomide once daily on days 1-5. Treatment with temozolomide repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline, 6 months, 12 months.

Survival and Progression-free Survival by O(6)-Methylguanine-DNA Methyltransferase (MGMT) Methylation Status
时间窗: Registration to 3 years
Survival time is defined as time from registration to date of death from any cause. Progressive Disease (PD) is defined as 25% or \> increase in the cross-sectional area of enhancing or non-enhancing tumor on consecutive MRI scans, or any new area(s) of tumor. Under exceptional circumstances, disease progression may be declared in the absence of an increase in tumor size based on "clinical deterioration" including the need for increasing doses of steroid and/or a worsening Karnofsky Performance Status(KPS) / Neurologic Function Score(NFS). Survival and progression-free survival are estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact.
Overall Survival Rate at 3 Years
时间窗: Registration to 3 years
Survival time is defined as time from registration to date of death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. This analysis was planned to occur when all patients had been potentially followed for at least 3 years.
Progression-free Survival
时间窗: From registration to last follow-up, up to 7.1 years. Analysis occurs after all patients have been on study for at least 3 years.
Progressive Disease (PD) is defined as 25% or \> increase in the cross-sectional area of enhancing or non-enhancing tumor on consecutive MRI scans, or any new area(s) of tumor. Under exceptional circumstances, disease progression may be declared in the absence of an increase in tumor size based on "clinical deterioration" including the need for increasing doses of steroid and/or a worsening Karnofsky Performance Status(KPS) / Neurologic Function Score(NFS). Progression-free survival time is defined as time from registration to date of progressive disease or death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. Median survival time is reported.
Quality of Life as Measured by the Functional Assessment of Cancer Therapy Scale With Brain Module (FACT-BR)
时间窗: Baseline, 6 months, and 12 months.
Functional Assessment of Cancer Therapy Scale with brain module (FACT-BR): a 50-question self-report questionnaire contains the following domains (scales): Physical well-being (7 questions totalling 0-28), social/family well-being (7 questions totalling 0-28), emotional well-being (6 questions totalling 0-24), functional well-being (7 questions totalling 0-28) and brain cancer subscale which contains concerns relevant to patients with brain tumors (19 questions totalling 0-76). Each question has a value 0-4. For some questions a higher indicates better outcome and others are the opposite. The former are summed as is, the latter are reversed in value before adding, such that each domain ranges from 0 to 4 multiplied by the number of questions in the domain, with 0 indicating worst and the highest possible value indicating best outcome. The FACT-Br total (0-184) is obtained by adding all domains together if the overall question response rate is greater than 80%.
Neurocognitive Function
时间窗: Baseline, 6 months, and 12 months.
Hopkins Verbal Learning Test (HVLT) is a test measuring learning memory retrieval, and memory consolidation processes.; Controlled Oral Word Association Test (COWAT) is a test of phonemic verbal fluency. The patient produces as many words as possible in 1 min. (each) for a specific letter (C, F, L or P, R, W).; Trail Making Test (TMT) is a measure of visuospatial scanning, attention, sequencing, and speed in Part A (TMT A) and executive function in Part B (TMT B). Patients must "connect the dots" either in a numbered sequence or alternating letters and numbers. Difference between pre-treatment baseline and follow-up assessment scores determined by the reliable change (RC) index, using a 90% confidence interval to designate statistically significant change.
