Time frame
From randomization to last follow-up: weekly during treatment, then 1, 3, 6, 9, 12, 18, 24, 30, 36, 48, and 60 months after end of protocol treatment, then annually. Maximum follow-up at time of reporting was 7.3 years. Two-year rates reported here.

What was measured

A lung cancer death is defined as cause of death designated as lung cancer or death with any evidence of disease progression at any site without a direct evidence of other cause of death. Time to lung cancer death is defined as time from randomization to the date of lung cancer death, last known follow-up (censored), or death without lung cancer (competing risk). Lung cancer death rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided.

Analysis population: Eligible participants

Groups in this outcome

Standard Radiation Therapy

60 Gy radiation therapy in 30 once daily fractions concurrent with weekly carboplatin and paclitaxel.

Adaptive Radiation Therapy

A maximum of 80.4 Gy radiation therapy in 30 once daily fractions concurrent with weekly carboplatin and paclitaxel. Radiation therapy dose is individualized for final 9 fractions based on imaging results from PET/CT scan between fractions 18 and 19.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
