  1. Expression of SPHK1 protein was analyzed in 124 cases of esophageal squamous carcinoma. After staining, slides were evaluated by two pathologists. SPHK1 expression was determined by scoring intensity and percentage of cell staining. Tissues with no staining were rated as 0; those with faint staining or moderate to strong staining in < 25% of cells as 1; with moderate staining or strong staining in 25-50% of cells as 2; and with strong staining in > 50% of cells as 3. Statistical analysis indicated that in the esophageal carcinoma, SPHK1 expression was correlated with depth of tumor invasion (P < 0.0001) and lymph node metastasis (P = 0.016). There was no significant association with age, sex or tumor differentiation.
