Abstract

BACKGROUND: Glioblastoma, the most common primary brain tumor in adults, is usually rapidly fatal. The current standard of care for newly diagnosed glioblastoma is surgical resection to the extent feasible, followed by adjuvant radiotherapy. In this trial we compared radiotherapy alone with radiotherapy plus temozolomide, given concomitantly with and after radiotherapy, in terms of efficacy and safety. METHODS: Patients with newly diagnosed, histologically confirmed glioblastoma were randomly assigned to receive radiotherapy alone (fractionated focal irradiation in daily fractions of 2 Gy given 5 days per week for 6 weeks, for a total of 60 Gy) or radiotherapy plus continuous daily temozolomide (75 mg per square meter of body-surface area per day, 7 days per week from the first to the last day of radiotherapy), followed by six cycles of adjuvant temozolomide (150 to 200 mg per square meter for 5 days during each 28-day cycle). The primary end point was overall survival. RESULTS: A total of 573 patients from 85 centers underwent randomization. The median age was 56 years, and 84 percent of patients had undergone debulking surgery. At a median follow-up of 28 months, the median survival was 14.6 months with radiotherapy plus temozolomide and 12.1 months with radiotherapy alone. The unadjusted hazard ratio for death in the radiotherapy-plus-temozolomide group was 0.63 (95 percent confidence interval, 0.52 to 0.75; P<0.001 by the log-rank test). The two-year survival rate was 26.5 percent with radiotherapy plus temozolomide and 10.4 percent with radiotherapy alone. Concomitant treatment with radiotherapy plus temozolomide resulted in grade 3 or 4 hematologic toxic effects in 7 percent of patients. CONCLUSIONS: The addition of temozolomide to radiotherapy for newly diagnosed glioblastoma resulted in a clinically meaningful and statistically significant survival benefit with minimal additional toxicity.

  • The standard treatment for high-grade gliomas such as glioblastoma is surgery followed by chemotherapy and radiation therapy.

    “The standard treatment for high-grade gliomas such as glioblastoma (grade IV) is surgery followed by chemotherapy and radiation therapy [45].”

    From 5-Aminolevulinic Acid as a Theranostic Agent for Tumor Fluorescence Imaging and Photodynamic Therapy (2023) · cites this paper as [45]

    The Abstract describes surgery followed by radiotherapy as the then-current standard of care for newly diagnosed glioblastoma; it says adjuvant chemotherapy was commonly prescribed in the United States and tests adding temozolomide. It does not establish surgery, chemotherapy, and radiation as the standard treatment for high-grade gliomas generally. (LLM, conf=0.87)

  • Performance improvements of boundary detection for tumor core (TC) and whole tumor (WT) may contribute to the model's clinical impact and relevance because TC is considered for surgery and WT for radiotherapy.

    “Since the current clinically actionable sub-compartments are TC (i.e., considered for surgery) and WT (i.e., considered for radiotherapy)42, performance improvements of their boundary detection may contribute to the model’s clinical impact and relevance.”
  • Stupp et al. reported that TMZ plus radiation in GBM patients gave about a 20% increase in progression-free survival compared with radiation alone.

    “Stupp et al. originally reported that treatment of patients with GBM with TMZ and radiation resulted in an approximately 20% increase in progression-free survival compared with radiation therapy alone.39”
  • A 20% increase in survival was considered biologically significant when comparing TMZ with T/N-treated mice.

    “An effect size of 20% increase in survival was considered to be biologically significant when comparing survival in TMZ versus combination T/N-treated mice.39”
  • MFH combined with radiotherapy in recurrent glioblastoma patients increased median survival to 13.4 months compared to 6.2 months in historical controls.

    “An increase of median survival of 13.4 months for patients treated with a combination of MFH and radiotherapy after glioblastoma recurrence was obtained (Figure 7E). As compared to the abovementioned historical control group, where the median survival after recurrence was 6.2 months, this increase is substantial.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
