CKS1B and melanoma: Notably, expression of cytoplasmic Cks1 was significantly higher in primary melanomas from patients with a positive sentinel lymph node metastasis compared to primary melanomas from patients with a negative sentinel lymph node biopsy (55.7 ± 33.4 versus 36.6 ± 34.6, respectively, p = 0.01 for cytoplasmic Cks1 labeling index).
