AI Article Synopsis

  • Ovarian cancer is a serious health threat that often goes unnoticed, highlighting the importance of developing effective prevention strategies.
  • Recent research suggests that constant ovulation is linked to increased cancer risk, but the use of oral contraceptives may offer some protective benefits.
  • Alternative methods, like using nonsteroidal anti-inflammatory drugs to temporarily halt ovulation, could be beneficial for women who are at high risk for the disease, but more studies are needed to confirm these findings.

Article Abstract

Ovarian cancer is a silent killer. There is a need to intensify research efforts on prevention strategies. The causative role of incessant ovulation has been supported by the protective effect of oral hormonal contraceptives. The released follicular fluid in the process of ovulation bathes not only the surface of the ovary but also the fimbrial end of the fallopian tube. Evidence has been accumulating about a fimbrial tubal origin for ovarian high-grade serous carcinoma, and for the potential of opportunistic or elective salpingectomy as an intervention strategy. Alternatively, periodic suppression of ovulation could be beneficial among women who have no need or are not using oral hormonal contraceptives. Rupture of the ovarian follicle releasing the ovum and follicular fluid is a prostaglandin-mediated inflammatory process. It can be stopped by nonsteroidal anti-inflammatory drugs, leading to pharmacologic production of a luteinized unruptured follicle, simulating a normal non-conception cycle with unaltered steroid patterns/levels and cycle length. Non-hormonal periodic interruption of incessant ovulation could be recommended for women who are at high risk of ovarian cancer, but further research is needed to validate the potential of this approach.

Article Synopsis
  • Incessant ovulation contributes to ovarian high-grade serous carcinomas (HGSC), which primarily arise from the fallopian tube epithelium (FTE), and receptor tyrosine kinase (RTK) ligands play a key role in this process.
  • A study investigated follicular fluid exosomes from women undergoing in vitro fertilization to identify RTK ligands and their impact on FTE cells, using various RTK inhibitors.
  • The findings revealed that FF exosomes were rich in transformative abilities and essential EGFR ligands, promoting cell growth and migration, indicating their significant contribution to HGSC development.

Estrous cycles are recurring changes in therian mammals induced by estrogen, progesterone, and other hormones culminating in endometrial proliferation, ovulation, and implantation if fertilization occurred. In women, the estrous cycle is the menstrual cycle; but, unlike most mammals, the end of an infertile cycle is marked by endometrial sloughing and the start of another without an anestrous phase. Women stop cycling at menopause, while in most mammals, cycles continue until death.

Incessant ovulation is believed to be a potential cause of epithelial ovarian cancer (EOC). Our previous investigations have shown that insulin-like growth factor (IGF2) and hepatocyte growth factor (HGF) in the ovulatory follicular fluid (FF) contributed to the malignant transformation initiated by p53 mutations. Here we examined the individual and synergistic impacts of IGF2 and HGF on enhancing the malignant properties of high-grade serous carcinoma (HGSC), the most aggressive type of EOC, and its precursor lesion, serous tubal intraepithelial carcinoma (STIC).

A leading theory for ovarian carcinogenesis proposes that inflammation associated with incessant ovulation is a driver of oncogenesis. Consistent with this theory, nonsteroidal anti-inflammatory drugs (NSAIDs) exert promising chemopreventive activity for ovarian cancer. Unfortunately, toxicity is associated with long-term use of NSAIDs due to their cyclooxygenase (COX) inhibitory activity.

During human evolution, major changes in our societal conditions and environment took place without sufficient time for concomitant genetic alterations, leading to out of step adaptation and diseases in women. We first discuss recent societal adaptation mismatch (menstrual bleeding; increases in cancers of reproductive organs, endometriosis; mother's nursing; polycystic ovarian syndrome; transgenerational epigenetic modifications), followed by Darwinian out of step adaptation (labor difficulties; sex chromosomes, human diseases and sex disparity in genomic DNA). We discuss the evolutionary basis of menstrual bleeding, followed by recent increases in cancers of reproductive organs and endometriosis.
