Significant tendency correlations between SST2 and SST3 expression were frequently observed (e.g. adrenocortical tumors (Spearman rho = 0.508, p < 0.001), ovarian carcinomas (rho = 0.297, p = 0.037), endometrial carcinomas (rho = 0.583, p < 0.001), renal clear cell carcinomas (rho = 0.355, p = 0.002), and melanomas (rho = 0.363, p < 0.001)). Here, SSTR2 is linked to melanoma.
