- Overall survival (OS) [ Time Frame: From the date of randomization and the date of death due to any cause, assessed up to 5 years ]Will compare the distributions of OS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of OS for each arm will be estimated using the Kaplan-Meier method. The associated 90% confidence interval (CI) will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios will be estimated using a stratified Cox regression model.
- Local-failure-free survival (LFFS) [ Time Frame: From randomization to local disease progression or death due to any cause, whichever occurs first, assessed up to 5 years ]Will compare the distributions of LFFS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of LFFS for each arm will be estimated using the Kaplan-Meier method (1958). The associated 95% CI will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios for LFFS will be estimated using a stratified Cox regression model.
- Distant-metastases-free survival (DMFS) [ Time Frame: From randomization to distant metastases or death due to any cause, whichever occurs first, assessed up to 5 years ]Will compare the distributions of DMFS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of DMFS for each arm will be estimated using the Kaplan-Meier method (1958). The associated 95% CI will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios for PFS will be estimated using a stratified Cox regression model.
- Progression-free survival (PFS) [ Time Frame: From randomization to any documented progression or death due to any cause, whichever occurs first, assessed up to 5 years ]Will compare the distributions of PFS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of PFS for each arm will be estimated using the Kaplan-Meier method (1958). The associated 95% CI will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios for PFS will be estimated using a stratified Cox regression model.
- Incidence of treatment-related toxicity [ Time Frame: Up to 5 years ]Adverse events (AEs) will be graded with Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. All adverse events, adverse events leading to withdrawal, interruption or modification of protocol treatment, grade >= 3 adverse events, and serious adverse events will be summarized. Deaths and cause of death will be summarized. The rate of treatment-related adverse events will be reported with the frequency and severity (e.g., type, grade, and attribution) by arm.
- Quality of Life (QOL)/patient-reported Outcome (PRO) [ Time Frame: Up to 5 years ]Measured by European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaires.
- Degree of under-staging, concordant and upstaging between centrally-reviewed clinical staging and pathologic staging [ Time Frame: Up to 5 years ]For each subject, the centrally-reviewed clinical staging (based on positron emission tomography, computed tomography and/or magnetic resonance imaging) will be compared with pathologic staging to determine whether it is under-staging (clinical staging is more extensive than pathologic staging), concordant (clinical staging is same as pathologic staging), or upstaging (clinical staging is less extensive than pathologic staging). The proportion of under-staging, concordant and upstaging, along with the associated 95% confidence intervals, will be reported.
- Association between radiation dose to gross residual disease and local control [ Time Frame: Up to 5 years ]Gross residual disease and local failure will be analyzed as competing risk data (death without gross residual disease or death without local failure as the respective competing event). Association between radiation dose to gross residual disease and local failure will be evaluated similarly in multivariable analyses using Fine-Gray regression model.
- Rate of R0/R1 and R2 resections, by type of procedures (extended pleurectomy/decortication (P/D), P/D and partial pleurectomy) [ Time Frame: Up to 5 years ]Proportions of R0/R1 and R2 resections, by type of procedures (extended pleurectomy/decortication (P/D), P/D and partial pleurectomy), along with 95% confidence intervals, will be reported.
