AI Article Synopsis

  • High-grade serous ovarian carcinoma (HGSOC) is a really serious type of cancer that affects women and is hard to prevent.
  • Researchers found that a hormone called progesterone can help stop this cancer from happening and spreading.
  • The study showed that progesterone works better in certain models and may encourage cancer cells to die, showing promise for using it as a way to prevent this disease.

Article Abstract

High-grade serous ovarian carcinoma (HGSOC) is one of the most fatal gynecological cancers and has no effective prevention strategies. Herein, we demonstrated that progesterone significantly inhibited the occurrence, metastasis, and ascites of ovarian cancer , and the tumor inhibition effect of progesterone was in the tubo-ovarian intrabursal model than in the intraperitoneal or subcutaneous models. Further data demonstrated that progesterone-treated fallopian tube fibroblasts conditioned medium significantly inhibit HGSOC precancerous cell viability by inducing pyroptosis via the IL-6/ROS/NLRP3/GSDMD pathway, implying that the oviduct microenvironment may enhance progesterone's protective effects on ovarian cancer. This study elucidated progesterone inhibiting ovarian cancer mechanism and provided evidence for progesterone as a chemo-preventive role for HGSOC.

Aims: Classification and risk stratification of endometrial carcinoma (EC) has transitioned from histopathological features to molecular classification, e.g. the ProMisE classifier, identifying four prognostic subtypes: POLE mutant (POLEmut) with almost no recurrence or disease-specific death events, mismatch repair deficient (MMRd) and no specific molecular profile (NSMP), with intermediate outcome and p53 abnormal (p53abn) with poor outcomes.

Accurate cancer risk estimation is crucial to clinical decision-making, such as identifying high-risk people for screening. However, most existing cancer risk models incorporate data from epidemiologic studies, which usually cannot represent the target population. While population-based health surveys are ideal for making inference to the target population, they typically do not collect time-to-cancer incidence data.
