Figure 2From: Pituitary tumor-transforming gene expression is a prognostic marker for tumor recurrence in squamous cell carcinoma of the head and neck Distribution of PTTG expression in primary tumors with different pN stages. Boxplot shows PTTG expression of all analyzed primary tumors (n = 89) grouped to their corresponding pN-stages (a). The pN-stage correlated to PTTG expression level with a significance of P = 0.021. Thereby significant (P = 0.016) differences between the pN0 (n = 25, negative) and pN+ (n = 64, positive) staged patients could be detected (b).Back to article page
