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

Overall survival time is defined as time from randomization to the date of death from any cause or last known follow-up (censored). Survival rates are estimated using the Kaplan-Meier method. The protocol specifies that the distributions of survival 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.
