(A) High cytoplasmic SK1 expression in a low S1P4 expression background is associated with shorter disease-free survival compared with patients with low tumour S1P4 and SK1 expression. (B) High cytoplasmic SK1 expression in a low S1P4 expression background is associated with shorter disease-specific survival compared with patients with low tumour S1P4 and SK1 expression. (C) High SK1 or S1P4 expression is associated with shorter disease-specific survival compared with patients with low SK1 and S1P4 expression in their tumours.
