TROP2 NMR Concordance Study

Because our study is a cross-sectional study, no Discontinuation criteria were set for stage 1\&stage2. The target of stage2 is to accrue a minimum of 1,000 positive samples and 1,000 negative samples at the central lab. Enrollment will be terminated once these accrual targets are achieved; no further specimens will be collected thereafter, even if the total number of specimens does not reach 2,800, or it is also possible that the final enrollment may exceed 2,800 participants.
