    Journal: Gynecol Obstet Invest; 2021; 86(1-2):162-169. PubMed ID: 33640886.
    Abstract:
    OBJECTIVE: The aim of the study was to determine the influence of beta-adrenoceptor (ADRB) antagonists on contractile activity of the nonpregnant human uterus in patients affected by gynecological malignancies. DESIGN: This was a controlled and prospective ex vivo study. SETTING: The work was conducted as a collaboration between 4 academic departments. MATERIALS AND METHODS: Myometrial specimens were obtained from women undergoing hysterectomy for benign gynecological disorders (reference group; N = 15), and ovarian (N = 15), endometrial (N = 15), synchronous ovarian-endometrial (N = 3), and cervical cancer (N = 10). Contractions of myometrial strips in an organ bath before and after applications of ADRB antagonists (propranolol, bupranolol, SR 59230A, and butoxamine) were studied under isometric conditions. RESULTS: Propranolol and bupranolol attenuated contractions in the endometrial and cervical cancer groups similar to that in the reference group (all p < 0.05), whereas opposite effects were observed in the ovarian and synchronous ovarian-endometrial cancer groups. SR 59230A and butoxamine significantly increased contractions in the ovarian cancer group (both p < 0.001). LIMITATIONS: These results require now to be placed into a firm clinical context. CONCLUSIONS: Our study indicates that ovarian cancer considerably alters contractile activity of the nonpregnant human uterus in response to ADRB antagonists. This suggests a pathogenetic role of beta-adrenergic pathways in this malignancy. Furthermore, propranolol and bupranolol substantially influence spontaneous uterine contractility.
