Spss advanced statistic 21

Statistical analysis was performed using the statistical package SPSS Advanced Statistic 21 (SPSS Inc, Chicago, IL, USA). The correlations among PTEN, phospho-AKT, and Rictor expression, and between the three markers and individual tumor features were determined using the Fisher test. Statistical significance was based on a 5% (0.05) significance level. Cancer-specific overall survival analysis was performed using the Kaplan–Meier method and both the Tarone–Ware and the log-rank (Mantel–Cox) tests were used to investigate the relationship between different parameters and cancer-specific overall survival.

Statistical analysis was performed using the statistical package SPSS Advanced Statistic 21 (SPSS Inc, Chicago, IL, USA). The associations between Foxp3+ cells and the site of infiltrations; the histological subtype; the histological grade; the presence of lymphatic invasion of tumor cells; the expression of ER, PR, and c-erBb-2 receptors; the number of alive or dead subjects were determined using the Bonferroni corrected post-hoc ANOVA test. Due to the low number of samples within the groups of solid carcinomas and anaplastic carcinomas, these two groups were merged for statistical purposes. Statistical significance was based on a 5% (0.05) significance level. Cancer-specific overall survival analysis was performed using the Kaplan–Meier method and both the Tarone–Ware and the log-rank (Mantel–Cox) tests were used to evaluate the relationship between OS and other variables.
