Failure-specific prognostic factors after continuous hyperfractionated accelerated radiotherapy (CHART) or conventional radiotherapy in locally advanced non-small-cell lung cancer: a competing risks analysis.

Patients receiving conventional radiotherapy failed earlier compared to the patients in the CHART arm and advanced clinical stage was asso- ciated with a relatively earlier failure. The results of hypothesis testing are shown in Table 3 where the Hcomb was significant for both the treatment arm (2P = 0.005) and the clinical stage (2P = 0.004), whereas a borderline significance was observed for age (2P = 0.08).
