Expression level of wild-type survivin in gastric cancer is an independent predictor of survival

Table 1 Relationship among expression levels of survivin variants and clinicopathologic parameters, proliferative activity or apoptosis

Two-tailed P values were calculated by the Mann-Whitney U test. Differentiated type: Papillary type, Tubular type. Undifferentiated type: Poorly differentiated type, Signet ring cell type, Mucinous type. Not invasion: No invasion of the serosa. Invasion: invasion of the serosa.
