Figure 3From: Pituitary tumor-transforming gene expression is a prognostic marker for tumor recurrence in squamous cell carcinoma of the head and neck PTTG mRNA expression in primary tumors of patients with tumor recurrences. (a) Boxplot shows the PTTG expression in primary tumors of all patients (n = 89) who suffered from a recurrence (positive, n = 49) versus the patients who did not develop a recurrence (negative, n = 40) within the 5-years observation period (P = 0.009). Boxplot (b) shows the distribution of PTTG mRNA levels in primary tumors in comparison to those levels in tumors of pN0 (n = 25) staged patients with (positive) and without (negative) a tumor recurrence (P = 0.006).Back to article page
