Risk Factors and Pathogenesis
The development of endometrial cancer is influenced by multiple factors:
Age: After menopause, the risk rises dramatically; most instances are detected in women over 60.
Hormonal imbalances: One of the main causes is exposure to estrogen, especially when progesterone is not present. Elevated estrogen levels are frequently associated with obesity and polycystic ovarian syndrome (PCOS), which increases risk.
Genetics: Individuals may be predisposed by mutations in genes such as MLH1 and PTEN.
Lifestyle factors: Smoking, diet, and physical inactivity could all be important.
The etiology of endometrial cancer is a multifactorial interaction between hereditary and environmental variables. Progesterone inhibits the action of estrogen on the growth of endometrial cells. Tumor formation and unchecked cell proliferation can result from imbalances in this balance, which are frequently caused by chronic exposure to estrogen or a lack of progesterone. Furthermore, oncogenes and tumor suppressor genes can be inactivated or activated by genetic alterations, which accelerates the development of cancer.
Types and Diagnosis
Two primary kinds of endometrial cancer can be generally classified as follows:
Type I: These makeup around 80% of cases, have a better prognosis, and are usually estrogen-receptor positive.
Type II: These tend to be more aggressive and have a worse prognosis. They often have high-grade histology and are estrogen-receptor-negative.
Increasing survival rates require early diagnosis. Abnormal vaginal discharge, pelvic pain, and abnormal uterine bleeding are among the symptoms. For more vulnerable women, screening with transvaginal ultrasound or endometrial biopsy is advised.
Treatment and Prognosis
The stage, grade, and type of the tumor are among the many variables that determine the treatment options for endometrial cancer. The cornerstone of treatment is surgery, which frequently includes bilateral salpingo-oophorectomy, lymphadenectomy, and hysterectomy. In certain situations, hormone therapy or radiation therapy may be the main form of treatment, or they may be used in addition to surgery.
The prognosis for endometrial cancer is generally favorable, with early-stage illness showing five-year survival rates above 80%. However, aggressive subtypes and advanced stages impair the prognosis.
Genistein
Because of its possible health benefits, genistein—an isoflavone molecule found in legumes like soybeans—has attracted scientific attention. This study looks at preclinical data that suggests genistein has a variety of pharmacological effects to give readers a thorough grasp of its possible therapeutic uses. Because genistein shares structural similarities with the female hormone estrogen, it has somewhat less potent effects on human health than estrogen. Its varied non-hormonal effects, in addition to its estrogenic activity, add to its potential health benefits.
The amount of genistein that the body can absorb and use, or its bioavailability, is still quite low. To optimize its therapeutic potential, more investigation into improving bioavailability—possibly using nanotechnology delivery systems—is essential.
Health Benefits
Antioxidant and Anti-inflammatory Activities
Free Radical Scavenging: Free radicals are very reactive chemicals that damage cells and are linked to chronic diseases like cancer and heart disease. Genistein functions as a strong antioxidant by scavenging these molecules. Genistein lowers oxidative stress by scavenging these free radicals, safeguarding cells, and maybe lowering the incidence of certain disorders.
Modulation of Inflammation: Although persistent inflammation can be harmful, it is a normal immunological response. By reducing the activity of inflammatory-related enzymes and signaling pathways, genistein may be able to mitigate the negative consequences of inflammation and even provide relief from autoimmune disorders and arthritic conditions.
Cardiovascular Protection
Lipid Metabolism Improvement: Genistein can lead to a better lipid profile by raising "good" HDL cholesterol and lowering "bad" LDL cholesterol levels. This may lessen the chance of atherosclerosis, or the accumulation of plaque in the arteries, which raises the risk of strokes and heart attacks.
Blood Pressure Regulation: Based on its antioxidant and anti-inflammatory qualities as well as its propensity to affect blood vessel function, genistein may have modestly reduced effects on blood pressure, according to certain studies. Together with better lipid metabolism, this may enhance general cardiovascular health.
Cancer Prevention
Estrogen Receptor Binding: Because genistein and estrogen share a structural resemblance, it can bind to estrogen receptors, albeit the precise mechanisms underlying this binding are complex. In some cases, this may be helpful, especially in cases of malignancy like breast cancer, where specific tumor cells need estrogen to proliferate. Genistein may be able to prevent the growth of cancer cells stimulated by estrogen by binding to these receptors.
Additional Mechanisms: In addition to binding to the estrogen receptor, genistein may also have anti-cancer effects by causing cancer cells to undergo programmed cell death, preventing angiogenesis—the development of new blood vessels necessary for tumor growth—and boosting the immune system's capacity to identify and eliminate cancer cells [1].
Role of Genistein in Endometrial Cancer
Asian communities have lower rates of endometrial cancer than those in Western nations, and this difference may be related to food. Many Asian diets include a lot of soy-rich foods, especially those high in genistein, which may help prevent cancer.
By subjecting endometrial cancer cells to varying genistein concentrations, researchers were able to examine the effects of the substance on the cells. They discovered that, at lower, more practical levels, genistein produced a variety of alterations in gene expression, possibly affecting pathways involved in the genesis of tumors. This implies that, depending on dietary intake levels, genistein may have cancer-preventive benefits.
Higher genistein concentrations, however, primarily activated genes related to the stress response, which raises questions regarding the validity of earlier research with non-physiological dosages. Furthermore, Genistein’s involvement in endometrial cancer was complicated by the fact that some of its effects included the estrogen system [2].
Genistein can act through different mechanisms of action in treating endometrial carcinoma such as:
PR Upregulation: Regardless of the presence or absence of the estrogen receptor (ER), genistein markedly raised the expression of both PR-A and PR-B. This action circumvented both epigenetic changes and conventional ER-mediated processes.
JNK Pathway and C/EBPβ Expression: Genistein increased JNK activation and phosphorylation of c-Jun while decreasing the expression of C/EBPβ. This implies that they are involved in the upregulation of PR caused by genistein.
FOXO1 Induction: One possible explanation for the anti-proliferative actions of genistein is that it increased the expression of FOXO1, a downstream target of the PI3K/PKB pathway.
Genistein also possesses several clinical implications while treating the disorder:
Better Prognosis: In young patients with endometrial cancer, elevated PR expression was linked to positive clinical outcomes.
Effects Not Dependent on ER: Genistein has anti-proliferative and PR-upregulating properties that work without the influence of ER, which may be advantageous in both ER-positive and ER-negative situations.
Fertility Preservation: Genistein may be used as a maintenance treatment for young patients who want to maintain their fertility because of its capacity to stimulate FOXO1 induction and PR expression, both of which are consistent with endometrial decidualization [3].
Preclinical and Clinical Trials
Many in vitro studies have been performed that have confirmed the effectiveness of genistein in endometrial cancer. However, only one clinical study is performed now and this has proven that genistein can be highly effective in treating endometrial cancer by acting through different mechanisms.
This clinical study investigated the potential use of the natural substance genistein in the treatment of endometrial cancer in young individuals who want to maintain their fertility. Because progesterone receptor (PR) expression is low in tumors, current therapies like progesterone frequently have limited effects. This study revealed the intriguing correlation between increased PR levels and higher survival rates, indicating that PR upregulation is an important target for better results.
Even in malignancies with a limited expression of the estrogen receptor, genistein efficiently elevated both PR-A and PR-B isoforms. This function, which involves downregulating C/EBPβ and activating the JNK pathway, appears to be independent of established pathways. In addition to upregulating PR, genistein also directly impeded the growth of tumors by causing apoptosis and cell cycle arrest as well as by increasing the tumor-suppressive protein FOXO1.
These results imply that genistein's ER-independent activity may help a larger spectrum of individuals in addition to increasing response rates to fertility-sparing therapies. Its promise as a maintenance medication for fertility preservation is consistent with its capacity to activate other important pathways and enhance PR expression [4].
Conclusion
Although preliminary studies suggest that genistein may be useful in the prevention and treatment of endometrial cancer, especially in younger individuals who want to maintain their fertility, the evidence is still inconclusive. Its broad range of anti-cancer potential, including direct tumor growth inhibition, and antioxidant, and anti-inflammatory effects, is demonstrated by preclinical research. Moreover, progesterone receptor (PR) expression appears to be significantly increased by genistein, which may improve outcomes for patients with endometrial cancer. This is entirely consistent with its potential to preserve fertility since increased PR expression and FOXO1 induction resemble processes that are essential for a successful pregnancy.
