DISEASE PROGRESSION, SECONDARY
The key endpoint was progression-free survival (PFS) and the main secondary endpoint was overall survival (OS). In this study, PFS refers to the time from the beginning of therapy to disease progression or death, and OS refers to the time from the start of therapy to death. For patients who did not meet the endpoints, the censoring date was the date when their last clinical assessment was conducted. Other endpoints such as objective response rate (ORR) and time to local progression (TTLP) were recorded in the RCT but were excluded for the construction of this prediction model.
