Ovarian cancer is a leading cause of death among women with gynecological cancers, and is often diagnosed at advanced stages, leading to poor outcomes. This review explores genetic aspects of high-grade serous, endometrioid, and clear-cell ovarian carcinomas, emphasizing personalized treatment approaches. Specific mutations such as TP53 in high-grade serous and BRAF/KRAS in low-grade serous carcinomas highlight the need for tailored therapies. Varying mutation prevalence across subtypes, including BRCA1/2, PTEN, PIK3CA, CTNNB1, and c-myc amplification, offers potential therapeutic targets. This review underscores TP53’s pivotal role and advocates p53 immunohistochemical staining for mutational analysis. BRCA1/2 mutations’ significance as genetic risk factors and their relevance in PARP inhibitor therapy are discussed, emphasizing the importance of genetic testing. This review also addresses the paradoxical better prognosis linked to KRAS and BRAF mutations in ovarian cancer. ARID1A, PIK3CA, and PTEN alterations in platinum resistance contribute to the genetic landscape. Therapeutic strategies, like restoring WT p53 function and exploring PI3K/AKT/mTOR inhibitors, are considered. The evolving understanding of genetic factors in ovarian carcinomas supports tailored therapeutic approaches based on individual tumor genetic profiles. Ongoing research shows promise for advancing personalized treatments and refining genetic testing in neoplastic diseases, including ovarian cancer. Clinical genetic screening tests can identify women at increased risk, guiding predictive cancer risk-reducing surgery.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors—serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol—and their roles in the pathophysiology of PCOS and associated psychiatric symptoms. Serotonin deficiency, commonly seen in PCOS patients, is associated with mood and eating disorders. Fluctuations in leptin, the satiety hormone, affect hypothalamic–pituitary–ovarian axis function and ovarian follicle maturation, increasing the risk of infertility. Elevated levels of kisspeptin in PCOS patients contribute not only to hormonal dysregulation but also to increased susceptibility to eating disorders such as bulimia and binge eating, likely due to its influence on the limbic system and glucose metabolism. Hyperinsulinemia and insulin resistance further impair reproductive and metabolic health, while promoting eating disorders such as binge eating and bulimia. Ghrelin and cortisol also emerge as significant factors. The review emphasizes the bidirectional relationship between PCOS and eating disorders, in which hormonal imbalances perpetuate psychiatric conditions, creating a vicious cycle. A multidisciplinary approach including gynecologists, endocrinologists, psychiatrists and nutritionists is recommended to ensure complex treatment. Early identification of those at risk through targeted screening and personalized interventions is key. Future research should focus on discovering the underlying hormonal mechanisms to improve treatment strategies and quality of life for women with PCOS.

Prolactin-inducible protein (PIP), also referred to as gross cystic disease fluid protein 15 (GCDFP-15), has been a trending topic in recent years due to its potential role as a specific marker in breast cancer. PIP binds to aquaporin-5 (AQP5), CD4, actin, fibrinogen, β-tubulin, serum albumin, hydroxyapatite, zinc α2-glycoprotein, and the Fc fragment of IgGs, and the expression of PIP has been demonstrated to be modulated by various cytokines, including IL4/13, IL1, and IL6. PIP gene expression has been extensively studied due to its captivating nature. It is influenced by various factors, with androgens, progesterone, glucocorticosteroids, prolactin, and growth hormone enhancing its expression while estrogens suppress it. The regulatory mechanisms involve important proteins such as STAT5A, STAT5B, Runx2, and androgen receptor, which collaborate to enhance PIP gene transcription and protein production. The expression level of PIP in breast cancer is dependent on the tumor stage and subtype. Higher expression is observed in early-stage tumors of the luminal A subtype, while lower expression is associated with luminal B, basal-like, and triple-negative subtypes, which have a poorer prognosis. PIP expression is also correlated with apocrine differentiation, hormone receptor positivity, and longer metastasis-free survival. PIP plays a role in supporting the immune system’s antitumor response during the early stages of breast cancer development. However, as cancer progresses, the protective role of PIP may become less effective or diminished. In this work, we summarized the clinical significance of the PIP molecule in breast cancer and its potential role as a new candidate for cell-based therapies.

Mesenchymal stem cells (MSCs) and their derivatives can be promising tools in oncology including ovarian cancer treatment. This study aimed to determine the effect of HATMSC2-MVs (microvesicles derived from human immortalized mesenchymal stem cells of adipose tissue origin) on the fate and behavior of primary ovarian cancer cells. Human primary ovarian cancer (OvCa) cells were isolated from two sources: post-operative tissue of ovarian cancer and ascitic fluid. The phenotype of cells was characterized using flow cytometry, real-time RT-PCR, and immunofluorescence staining. The effect of HATMSC2-MVs on the biological activity of primary cells was analyzed in 2D (proliferation, migration, and cell survival) and 3D (cell survival) models. We demonstrated that HATMSC2-MVs internalized into primary ovarian cancer cells decrease the metabolic activity and induce the cancer cell death and are leading to decreased migratory activity of tumor cells. The results suggests that the anti-cancer effect of HATMSC2-MVs, with high probability, is contributed by the delivery of molecules that induce cell cycle arrest and apoptosis (p21, tumor suppressor p53, executor caspase 3) and proapoptotic regulators (bad, BIM, Fas, FasL, p27, TRAIL-R1, TRAIL-R2), and their presence has been confirmed by apoptotic protein antibody array. In this study, we demonstrate the ability to inhibit primary OvCa cells growth and apoptosis induction after exposure of OvCa cells on HATMSC2-MVs treatment; however, further studies are needed to clarify their anticancer activities.

Background and Clinical Significance: Herlyn–Werner–Wunderlich (HWW) syndrome, also known as OHVIRA syndrome (Obstructed HemiVagina and Ipsilateral Renal Anomaly), is a rare congenital anomaly of the female urogenital system characterized by uterine duplication, unilateral vaginal obstruction, and renal agenesis on the same side. The condition often remains undiagnosed until adolescence, when it presents with palpable pelvic mass, dysmenorrhea, and chronic pelvic pain. Case report: We present the case of a 13-year-old female patient diagnosed with OHVIRA syndrome following imaging studies. Surgical treatment involved incision of the vaginal septum and evacuation of accumulated blood, leading to symptom resolution and restoration of reproductive tract patency. Conclusions: This article discusses the clinical characteristics, diagnostic challenges, and the importance of early surgical intervention, emphasizing the necessity of considering this syndrome in the differential diagnosis of adolescent females with cyclic abdominal pain and renal anomalies. Early diagnosis and treatment can prevent severe health complications and improve both patients’ quality of life and fertility.

This study investigates the impact of bisphosphonate therapy on the stomatognathic system in 80 patients with cancer of the breast and prostate with bone metastases. Bisphosphonates are integral for managing skeletal complications in these malignancies but are associated with bisphosphonate-related osteonecrosis of the jaw (BRONJ), affecting 0.8–18.5% of patients. BRONJ manifests with pain, neuropathy, tissue swelling, mucosal ulceration, tooth mobility, and abscesses, yet its pathogenesis remains elusive, complicating risk prediction. The research employed comprehensive dental and radiological evaluations. Dental status was assessed using DMFT and OHI-S indices, Eichner’s classification, and clinical periodontal measurements like the pocket depth (PD), clinical attachment loss (CAL), and modified Sulcus Bleeding Index (mSBI). A radiological analysis included panoramic X-rays for radiomorphometric measurements and TMJ lateral radiographs. Results indicated a significant decline in oral hygiene in patients with cancer after bisphosphonate therapy, marked by increased DMFT and OHI-S scores. Periodontal health also showed deterioration, with increased PD and CAL readings. The incidence of BRONJ symptoms was noted, although exact figures are not quantified in this The study also revealed changes in radiomorphometric parameters, suggesting bisphosphonates’ impact on bone density and structure. No substantial alterations were observed in TMJ function, indicating a need for extended observation to understand bisphosphonates’ long-term effects on the stomatognathic system. These findings highlight the importance of continuous dental monitoring and prophylaxis in patients undergoing bisphosphonate therapy. Implementing meticulous oral care protocols is essential for mitigating BRONJ risk and managing the complex oral health challenges in patients with cancer.
