FIG 2.

Time to treatment failure and overall survival of patients with complete response (CR). (A) Time to treatment failure and (B) overall survival were calculated from the time of CR. Patients were determined to have a CR by RECIST confirmed by 1 of 2 reference radiologists (RECIST cohort), a radiologic CR that could not be confirmed by the reference radiologists (UC RECIST), or major response with a negative biopsy (pathologic). The “other” group includes patients who had a CR by clinical evaluation but did not have radiologically assessable disease or patients who had a radiologic CR as assessed by an outside radiologist but for whom the outside scans were not available for review at our institution.
