SSTR2 and hepatocellular carcinoma: In the cores for which the TNM and grading data were available, a statistically significant negative correlation with the T status (tumor size) and also with the tumor stage was found for the SST2 in the hepatocellular carcinomas and particularly in the ovarian carcinomas (Fig. 3, with Kendall τ and Kruskal Wallis values of 0.037/0.089, and 0.004/0.013, respectively).
