Abstract：Objective To analyze factors influencing short-term effect of presurgical pharmacological thera-py and transsphenoidal microsurgery for somatotropinomas. Methods The clinical data of 53 patients underwent presurgical pharmacological therapy and transsphenoidal surgery for somatotropinomas were retrospectively analyzed in order to search for factors influencing effect of presurgical pharmacological therapy and transsphenoidal surgery for somatotropinomas. Results Serum GH inhibition rates decreased<50.00%from baseline in 62.26%of patients receiving presurgical pharmacological therapy. Statistical analysis concerning the influence of sex , neuropathological evaluation, tumor size and presence of invasion on presurgical pharmacological therapy effect were performed using a chi-squared test, no significant correlation was found among these factors and presurgical pharmacological therapy effect. Total remission rates were 43.40%, Statistical analysis concerning the influence of sex , neuropathological e valuation, tumor size, presence of invasion and presurgical pharmacological therapy effect on remission rate were performed using a chi-squared test, a significant correlation was found among tumor size, presence of invasion, presurgical pharmacological therapy effect and remission rate , while no significant correlation was found among the rest of the factors. Further Logistic regression analysis demonstrated a significant correlation among tumor size , presence of invasion and remission rate , while no significant correlation was found between presurgical pharmacolog-ical therapy effect and remission rate. Conclusions Presurgical pharmacological therapy effect revealed no signifi-cant correlation with sex, neuropathological evaluation, tumor size or presence of invasion. Total remission rate cor-related with tumor size and presence of invasion. A better presurgical pharmacological therapy effect may indicated a better outcome, while postoperative remission rate revealed no significant correlation with presurgical pharmacologi-cal therapy in our series.
