In the multivariate Cox regression analysis, the postoperative GH value was independently associated with the outcome (HR 1.042, 95% CI 1.004–1.081, p=0.030), as were the postoperative PRL value (HR 1, 95% CI 1,1.001, p=0.019), the ki-67 level (HR 2.43, 95% CI 1.109–5.330, p=0.026), the postoperative tumor diameter (HR 1.038 95% CI 0.997–1.080, p=0.068) and the expression of SSTRs 2 and 5. Here, PRL is linked to neoplasm.
