Primary Outcome Measures
- Modified Response Evaluation Criteria in Solid Tumors (RECIST) progression free survival [ Time Frame: From date of registration to date of first documentation of progression, assessed up to 3 years ] Will be assessed by modified RECIST 1.1. Will be evaluated using the method of Kaplan-Meier. Confidence intervals around the median will be calculated using the Brookmeyer-Crowley method, confidence intervals around landmark time points will use the Greenwood formula for standard errors.
- Overall survival [ Time Frame: From date of initial registration to date of death due to any cause, assessed up to 3 years ] Will be evaluated using the method of Kaplan-Meier. Confidence intervals around the median will be calculated using the Brookmeyer-Crowley method, confidence intervals around landmark time points will use the Greenwood formula for standard errors.
