: This article does not contain any studies with animals performed by any of the authors. All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. The tissue samples were retrieved from the archive of Obstetrics and Gynecology, Ludwig-Maximilians-University, Munich, Germany. The study was approved by the Ethics Committee of the Ludwig-Maximilians-University, Munich, Germany (approval number: 18-166). The tumor tissue re-used for our analysis had initially been collected for histopathological diagnostics. At the time, the tissue was examined for the current study all diagnostic procedures had already been fully completed and thus the tissue was classified as “left-over” material. Clinical data and tissue specimens were irreversibly anonymized prior to inclusion in the study. Researchers were blinded from patient data during experimental and statistical analysis.
