In patients with cervical cancer, the best discrimination was obtained for a cut-off value of post-therapeutic numbers of CD133+ CTCs ≥ 2/ml (83.87% sensitivity and 100% specificity; Supplementary Figure S3D), numbers of CD49f+ CD133+ CTCs ≥ 2/ml (76.67% sensitivity and 100% specificity; Supplementary Figure S3E) and numbers of PD-L1+ CD49f+ CD133+ CTCs ≥ 2/ml (80% sensitivity and 100% specificity; Supplementary Fig. S3F). Here, PROM1 is linked to cervical cancer.
