  schema:description "A family of 'time to X' endpoints: how long until the cancer grows (TTP, which unlike PFS ignores deaths), until the patient needs another treatment (TTNT), until it spreads (metastasis-free survival), or until symptoms worsen. Each captures something patients care about that survival alone misses."@en ;
