ABSTRACT

Borderline ovarian tumors typically exhibit indolent behavior and boast a favorable prognosis; however, a subset of patients experiences disease recurrence and progression to low-grade ovarian carcinoma. The complex biology underlying these phenomena has been illuminated through molecular analyses. KRAS and BRAF mutations have emerged as recurrent ?ndings in borderline ovarian tumors. Speci?cally, KRAS mutations have been linked to a higher risk of recurrence and progression to low-grade ovarian carcinoma, while BRAF mutations seem to confer a protective e?ect, inducing a senescent state that mitigates the likelihood of progression. In this comprehensive review, we explore the biology and the molecular pro?le of borderline ovarian tumors, shedding light on recent discoveries that have enriched our comprehension. Additionally, we discuss the current state of borderline ovarian tumors management. Surgery remains the cornerstone of treatment. While cytotoxic therapies role is limited so far, molecular characterization emphasizes the imminent potential for personalized therapeutic approaches.


Os tumores borderline de ovário geralmente exibem comportamento indolente e apresentam prognóstico favorável; no entanto, um subconjunto de pacientes apresenta recorrência da doença e progressão para carcinoma de ovário de baixo grau. A biologia complexa subjacente a estes fenômenos foi iluminada através de análises moleculares. Mutações KRAS e BRAF surgiram como achados recorrentes em tumores borderline de ovário. Especificamente, as mutações KRAS têm sido associadas a um maior risco de recorrência e progressão para carcinoma de ovário de baixo grau, enquanto as mutações BRAF parecem conferir um efeito protetor, induzindo um estado senescente que mitiga a probabilidade de progressão. Nesta revisão abrangente, exploramos a biologia e o perfil molecular dos tumores borderline de ovário, lançando luz sobre descobertas recentes que enriqueceram nossa compreensão. Além disso, discutimos o estado atual do manejo de tumores borderline de ovário. A cirurgia continua sendo o pilar de tratamento. Embora o papel das terapias citotóxicas seja limitado até o momento, a caracterização molecular enfatiza o potencial iminente para abordagens terapêuticas personalizadas.

ABSTRACT

Objective To explore the antitumor effects of metformin on ovarian cancer cells in vitro, particularly on tumor cell proliferation, cell cycle, apoptosis, migration, and possible mechanism. Methods Ovarian cancer cell lines (A2780, CAOV3, and SKOV3) were treated with different concentrations of metformin. Their proliferation was explored using the MTT and clone formation assays, cell migration was examined using the scratch and Transwell assays, and cell cycle and apoptosis were examined using flow cytometry. In addition, metformin’s effects on the phosphorylation of AMPK and mTOR and the expression of CXCR4 and Wnt/β-catenin protein was measured by Western blot. Results The survival rates of ovarian cancer cells decreased significantly with increasing metformin concentration and metformin treatment time. The IC50 values of metformin at 48 h for A2780, CAOV3, and SKOV3 cells were 16.36, 36.65, and 43.44 mmol/L, respectively. Compared with the control group, the clone formation ability and cell migration ability of ovarian cancer cells were significantly inhibited by metformin treatment and cell cycle arrested at the G0/G1 phase, and the apoptosis rate increased. As metformin concentration increased, the expression of phosphorylated AMPK protein gradually increased, and the expression levels of phosphorylated mTOR, CXCR4, Dvl3, β-catenin, cyclin D1, and CDK1 decreased. Conclusion Metformin exerts an antitumor effect on ovarian cancer cells, which is related to the activation of AMPK to inhibit CXCR4-mediated Wnt/β-catenin signaling pathway.

ABSTRACT

ObjectiveThe active ingredients, action targets, and signaling pathways of Cuscutae Semen to control premature ovarian failure were initially predicted by network pharmacology and molecular docking techniques, and an animal model of premature ovarian failure was constructed to explore the mechanism of Cuscutae Semen based on lipid and atherosclerosis signaling pathways. MethodThe effective components and corresponding targets of drugs were obtained from Traditional Chinese Medicines Systems Pharmacology Platform (TCMSP), Swiss Target Prediction, Pharmmapper, and other databases. GeneCards database was used to collect disease-related targets. Venny2.1.0 online tool was used to screen out the intersection targets of drugs and diseases, and STRING database and Cytoscape v3.7.2 software were used to construct the network diagram of "drug-component-target" and protein-protein interaction (PPI). The gene ontology (GO) and the Kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses of the intersection targets were performed by running the R language script. The molecular docking technology was utilized to dock drug components with targets and visualize some of the docking results. The mice were randomly divided into a blank group, a model group, a Cuscutae Semen group, and an estradiol valerate group, and the ovarian premature failure model was prepared by chronic stress. The blank group and the model group were gavaged with the same amount of normal saline, and the Cuscutae Semen group was given a Cuscutae Semen decoction of 2.6 g·kg-1·d-1. The estradiol valerate group was given an estradiol valerate solution of 0.13 mg·kg-1·d-1. After four weeks, samples were collected, and hematoxylin-eosin (HE) staining was performed to observe the histopathological changes in the ovary. Serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), Muller's tube inhibitor/anti-Muller's tube hormone (AMH), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were determined by enzyme-linked immunosorbent assay (ELISA). The expression levels of extracellular regulatory protein kinase (ERK), nuclear transcription factor-κB p65 (NF-κB p65), nuclear transcription factor-κB suppressor α (IκBα), interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) were measured by Western blot. ResultA total of 171 targets of Cuscutae Semen for the prevention and treatment of premature ovarian failure were screened, mainly including tumor protein p53 (TP53), protein kinase B1 (Akt1), sarcoma (SRC), tumor necrosis factor (TNF), epidermal growth factor receptor (EGFR), etc. KEGG pathway enrichment analysis predicts that Cuscutae Semen is mainly involved in lipid and atherosclerosis, TNF signaling pathway, and TP53 signaling pathway to control premature ovarian failure. The animal experiments show that compared with the premature ovarian failure model group, the Cuscutae Semen group can significantly upregulate AMH, E2, and HDL-C (P<0.05, P<0.01), significantly downregulate LH, TC, and LDL-C (P<0.01), greatly reduce IL-1β, IL-6, and TNF-α protein levels, as well as ERK, NF-κB p65, and their phosphorylation levels (P<0.01). ConclusionCuscutae Semen can regulate hormone levels and improve ovarian function through a multi-component, multi-target, and multi-pathway approach, and the mechanism may be related to the regulation of lipid and atherosclerosis signaling pathways.

ABSTRACT

It is believed that kidney deficiency is the fundamental pathogenesis while liver constraint and spleen deficiency, and disharmony of chong (thorough vessel, 冲脉)and ren (conception vessel, 任脉) is the key pathogenesis of infertility patients who adopted controlled ovarian hyperstimulation of in vitro fertilization-embryo transfer (IVF-ET) programme. Therefore, the method of tonifying the kidneys dominantly and treating the liver and spleen simultaneously is proposed, and Chinese herbal medicine is suggested to be used in adjuvant treatment of staged IVF-ET controlled ovrian hyperstimulation. In the regulation stage, modified Liuwei Dihuang Pill (六味地黄丸) can be used to tonify kidney and supplement essence, fortify spleen and nourish liver; in the ovulation promotion stage, modified Wenjing Decoction (温经汤) should be used to warm kidney and assist yang, dispel stasis and nourish blood; in the pre-transplantation endothelial preparation stage, modified Shenling Baizhu Powder (参苓白术散) is suggested to fortify spleen and replenish qi, invigorate blood and resolve stasis; after the transplantation stage, modified Shoutai Pill (寿胎丸) or Taiyuan Decoction (胎元饮) can be taken to fortify spleen and tonify kidney, benefit qi and nourish blood.

ABSTRACT

Aim Based on the apoptotic pathway mediated by receptor interacting protein kinase(RIP)1-RIP3-mixed spectrum kinase domain like protein(MLKL), to explore the effects of naringenin on ovarian granulosa cell apoptosis in rats with polycystic ovary syndrome(PCOS). Methods SD rats were randomly assigned into normal control group, model group, naringenin group, RIP1 inhibitor(Nec-1)group, RIP1-RIP3-MLKL necrosis signal activator(Z-VAD-fmk)group, naringenin+Z-VAD-fmk group, 15 rats per group. ELISA method was performed to measure the levels of IL-1β and TNF-α in ovarian tissue. HE method was performed to observe the shape of the ovary. Granular cells were isolated from ovarian tissue, and flow cytometry was performed to measure apoptosis rate and necrosis rate. Immunohistochemistry was performed to measure the positive expression of p-RIP1 in ovarian tissue. Western blot was employed to detect the expression of RIP1-RIP3-MLKL pathway. Results RIP1 specific inhibitor Nec-1 and naringenin could block the phosphorylation and activation of RIP1, inhibit the RIP1-RIP3-MLKL signaling pathway, reduce the inflammation level in PCOS rats, and alleviate the necrosis and apoptosis of ovarian granulosa cells(P<0.05). Z-VAD-fmk could promote the activation of RIP1-RIP3-MLKL pathway, aggravate the apoptosis of ovarian granulosa cells, and partially weaken the anti-apoptosis effect of naringenin(P<0.05). Conclusions Naringenin may inhibit the apoptosis of ovarian granulosa cells in PCOS rats by blocking the activation of the necrotic apoptotic pathway mediated by RIP1-RIP3-MLKL.

ABSTRACT

ObjectiveTo objectively analyze the effects of traditional Chinese Medicine (TCM) multi-channel intervention on the ovarian function,TCM syndromes and natural conception of poor ovarian responders(kidney-Yin deficiency,liver depression and blood stasis pattern) who planned to receive another in vitro fertilization embryo transfer(IVF-ET)antagonist regimen. MethodThe 128 low-prognosis patients (kidney Yin deficiency,liver depression and blood stasis pattern) who attended the West China Second University Hospital, Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected,and then divided into the treatment group and the control group according to the random number table,with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone(DHEA),while the treatment group was treated with multi-channel TCM(oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema). After 3 menstrual cycles,the relevant indicators for ovarian function evaluation,TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment,the basal follicle stimulating hormone(bFSH),bFSH/basal luteinizing hormone(bLH),basal estradiol(bE2),antral follicle count(AFC),the number of oocytes obtained,the number of normal fertilization,the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment(P<0.05,P<0.01). For the control group, the bFSH/bLH and TCM syndrome scores were increased after treatment(P<0.05), while the bFSH,bFSH/bLH,bE2,AFC,the number of oocytes obtained,the number of normal fertilization,and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment,bFSH,bFSH/bLH,bE2,AFC,the number of normal fertilization,the number of superior embryos and TCM syndrome scores in the treatment group were better (P<0.05,P<0.01),while there was no significant difference in the number of oocytes obtained. After treatment,there were 3 cases of natural conception in the treatment group,while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency,liver depression and blood stasis pattern,multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH,bFSH/bLH values,improve the levels of bE2,increase AFC,the number of oocytes obtained,the number of normal fertilization and the number of superior embryos,improve ovarian function,menstruation and TCM syndromes,improve their quality of life,and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.

ABSTRACT

In recent years, with the continuous progress of medical technology, the survival rate of cancer patients after treatment has been continuously improved, and more and more young cancer patients begin to pay attention to the fertility problem after survival. For prepubertal or adolescent cancer patients who require urgent chemoradiotherapy, and for reproductive female patients, ovarian tissue cryopreservation (OTC) follows by transplantation is the only option to preserve their fertility at present. Although the OTC technology has been carried out as a routine clinical project in a few medical institutions in China, it is still in the stage of clinical trial research in majority medical institutions. There are still many technical and ethical challenges in clinical practice of OTC technology. Therefore, this paper discussed the ethical principles that should be followed in clinical practice of human OTC and transplantation, and briefly analyzed the corresponding ethical issues. When implementing this technology, the indications should be followed strictly, the wishes of patients should be respected and true and full informed consent should be obtained while ensuring that the cancer treatment of patients is not delayed. Besides, it is significants to accumulate enough experience for minor patients to fully protect their rights and interests and promote the construction of relevant national laws and regulations.

ABSTRACT

ObjectiveOvarian cancer is the third most common gynecologic cancer worldwide, with the second highest mortality rate among gynecologic cancers, and age-standardized rates are gradually increasing in many low- and middle-income countries. At present, its etiology and pathogenesis are not clear. There are no obvious symptoms in the early stage, and when the symptoms become obvious, it often indicates the advanced stage. The 5-year survival rate of the advanced stage is only 17%, which poses a great threat to women's health. Therefore, an in-depth study of the etiology and pathogenesis of ovarian cancer is very important to the exploration of prevention and treatment methods for ovarian cancer. Based on the clinical characteristics of ovarian cancer in traditional Chinese and Western medicine, and combined with the existing evaluation methods of animal models, this study evaluated the animal model of ovarian cancer, and provided analysis and suggestions. MethodThis study searched China National Knowledge Infrastructure (CNKI), Wanfang data, VIP information database, and PubMed database using the keywords "ovarian cancer" and "animal model", excluded the articles that did not meet the criteria, and then classified the remaining studies. Combined with the clinical diagnostic criteria of Western medicine and traditional Chinese medicine syndrome differentiation, the related indicators of ovarian cancer animal models were assigned and the degree of agreement was evaluated. ResultThe use of the transplanted animal model exhibited the highest frequency, followed by that of the induced model. The degree of agreement of traditional Chinese medicine for each model was lower than that of Western medicine. The induced ovarian cancer model had a high degree of clinical agreement and was similar to human ovarian cancer in terms of tumor growth pattern, disease progression and complications, which is an ideal animal model of ovarian cancer. Although this animal model can simulate the etiology and pathogenesis of ovarian cancer to a certain extent and reflect some indicators of traditional Chinese and Western medicine, it lacks differentiation of traditional Chinese medicine syndromes. ConclusionOn the basis of the original model, the animal model of ovarian cancer was added with Qi deficiency syndrome, blood deficiency syndrome, Qi stagnation syndrome, blood stasis syndrome, heat-toxin syndrome, and Yang deficiency syndrome to establish an animal model combining traditional Chinese medicine disease and syndrome of ovarian cancer, which could better simulate the clinical actual situation of traditional Chinese and Western medicine and lay a solid foundation for the study of integrated traditional Chinese and Western medicine for the treatment of ovarian cancer.

ABSTRACT

ObjectiveTo investigate the effects of Xinjia Congrong Tusizi decoction (XJCTD) on ovarian functions in the rat model of premature ovarian insufficiency (POI) and decipher the mechanism of regulating the tumor suppressor protein (p53)/nuclear factor E2-related factor 2 (Nrf2) pathway to attenuate granulosa cell ferroptosis. MethodForty-eight SPF-grade female SD rats were randomized into control, model, low-, medium-, and high-dose (1.1, 2.2, 4.4 g·kg-1) XJCTD, and Western medicine (coenzyme Q10, 0.002 7 g·kg-1) groups, with eight rats in each group. The rat model of POI was established by gavage of triptolide (TP), and after successful modeling, each group was administrated with the corresponding drugs by gavage for 14 d. The body weight and ovarian weight of each rat were weighed and the ovarian index was calculated. The morphology of the ovarian tissue was observed by hematoxylin-eosin staining, and the proportions of growing follicles and atretic follicles were calculated. The serum levels of anti-Müllerian hormone (AMM), estradiol (E2), and follicle-stimulating hormone (FSH) were measured by enzyme-linked immunosorbent assay (ELISA). The DCFH-DA fluorescent probe was used to measure the reactive oxygen species (ROS) content in granulosa cells. The content of cellular Ferrous ion (Fe2+), lipid peroxide (LPO), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) was detected by colorimetry. The expression of the tumor suppressor protein p53,Nrf2, solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) was determined by immunohistochemistry and Western blot. ResultCompared with the control group, the model group showed decreased ovarian weight, body weight, and ovarian index (P<0.01), reduced ovarian tissue volume and proportion of growing follicles (P<0.01), increased proportion of atretic follicles (P<0.01), lowered AMH and E2 levels and elevated FSH level in the serum (P<0.01), and elevated levels of Fe2+, ROS, LPO, and MDA (P<0.01) and lowered levels of GSH and SOD in granulosa cells (P<0.01). Moreover, the modeling up-regulated the expression of p53 (P<0.01) and down-regulated the expression of Nrf2, SLC7A11, and GPX4 (P<0.05, P<0.01) in the ovarian tissue. Compared with the model group, XJCTD increased the body weight, ovarian weight, and ovarian index (P<0.01), alleviated the pathological changes in the ovarian tissue, increased the proportion of growing follicles (P<0.01), decreased the proportion of atretic follicles (P<0.01), and reduced the content of ROS in granulosa cells (P<0.05, P<0.01). In addition, medium- and high-dose XJCTD lowered the FSH level (P<0.01) and raised E2 and AMH levels (P<0.01) in the serum, reduced the Fe2+ content (P<0.05, P<0.01), and increased the SOD content (P<0.01) in granulosa cells. High-dose XJCTD reduced the LPO and MDA content (P<0.01) and increased the SOD content (P<0.01) in the granulosa cells, down-regulated the expression of p53 (P<0.05), and up-regulated the expression of Nrf2, SLC7A11, and GPX4 in the ovarian tissue (P<0.05, P<0.01). ConclusionXJCTD may protect the ovarian function in the rat model of POI by regulating the p53/Nrf2 signaling pathway to attenuate the ferroptosis of ovarian granulosa cells.

ABSTRACT

Immune evasion has made ovarian cancer notorious for its refractory features, making the development of immunotherapy highly appealing to ovarian cancer treatment. The immune-stimulating cytokine IL-12 exhibits excellent antitumor activities. However, IL-12 can induce IFN-γ release and subsequently upregulate PDL-1 expression on tumor cells. Therefore, the tumor-targeting folate-modified delivery system F-DPC is constructed for concurrent delivery of IL-12 encoding gene and small molecular PDL-1 inhibitor (iPDL-1) to reduce immune escape and boost anti-tumor immunity. The physicochemical characteristics, gene transfection efficiency of the F-DPC nanoparticles in ovarian cancer cells are analyzed. The immune-modulation effects of combination therapy on different immune cells are also studied. Results show that compared with non-folate-modified vector, folate-modified F-DPC can improve the targeting of ovarian cancer and enhance the transfection efficiency of pIL-12. The underlying anti-tumor mechanisms include the regulation of T cells proliferation and activation, NK activation, macrophage polarization and DC maturation. The F-DPC/pIL-12/iPDL-1 complexes have shown outstanding antitumor effects and low toxicity in peritoneal model of ovarian cancer in mice. Taken together, our work provides new insights into ovarian cancer immunotherapy. Novel F-DPC/pIL-12/iPDL-1 complexes are revealed to exert prominent anti-tumor effect by modulating tumor immune microenvironment and preventing immune escape and might be a promising treatment option for ovarian cancer treatment.

ABSTRACT

ABSTRACT Objective: The aim of this study is to investigate the molecular genetic causes of non-syndromic primary ovarian insufficiency (POI) cases with the gene panel based on next generation sequencing analysis and to establish the relationship between genotype and phenotype. Subjects and methods: Twenty three cases aged 14-40 years followed up with POI were included. Patients with a karyotype of 46, XX, primary or secondary amenorrhea before the age of 40, with elevated FSH (>40 IU/mL) and low AMH levels (<0.03 ng/mL) were included in the study. Molecular genetic analyzes were performed by the next generation sequencing analysis method targeted with the TruSightTM Exome panel. Results: Median age of the cases was 17.8 (14.0-24.3) years, and 12 (52%) cases admitted before the age of 18. Fifteen (65%) patients had consanguineous parents. In 2 (8.6%) cases, variants detected were in genes that have been previously proven to cause POI. One was homozygous variant in FIGLA gene and the other was homozygous variant in PSMC3IP gene. Heterozygous variants were detected in PROK2, WDR11 and CHD7 associated with hypogonadotropic hypogonadism, but these variants are insufficient to contribute to the POI phenotype. Conclusion: Genetic panels based on next generation sequencing analysis technologies can be used to determine the molecular genetic diagnosis of POI, which has a highly heterogeneous genetic basis.

ABSTRACT

ABSTRACT Ovarian steroid cell tumors are rare, representing less than 0.1% of all ovarian neoplasms. Among the myriad causes of hirsutism, ovarian tumors account for 1% of the reported cases. We present the case of a 49-year-old parous postmenopausal woman who sought medical attention for hirsutism for 2 years. This case illustrates the unusual and interesting connection between rare ovarian pathology and the clinical manifestation of hirsutism in a postmenopausal patient. Her ultrasonography and MRI showed a right adnexal mass of solid-cystic consistency with thin septations. Her laboratory workup revealed high levels of total testosterone of 256 ng/ml (8.4-48.1ng/ml) and free testosterone of 7.36 pg/ml (0.2-4.1 pg/ml), while DHEAS - 234 µg/dl (35.4-256 µg/dl) and CA125 - 15.8U/L (0.0-35 U/L) were in the normal range. She underwent exploratory laparotomy with a total abdominal hysterectomy and oophorectomy. Histopathological examination and immunohistochemistry conclusively established the presence of a steroid cell tumor, specifically classified as "Not Otherwise Specified"(NOS), in the right ovary.

ABSTRACT

Resumo Este artigo analisa as publicações de mulheres que sofrem da Síndrome dos Ovários Policísticos (SOP), em grupos na rede social Facebook. A SOP é uma síndrome metabólica experienciada por um vasto número de mulheres em idade fértil. Entre seus sintomas, destacam-se a acne, o aumento de peso e a presença de pelos indesejáveis. Já o tratamento está concentrado na mudança de estilo de vida associado a um controle da dieta e adoção de novos hábitos. Por meio da análise dos depoimentos e imagens postados pelas participantes dos grupos, que expressam as suas transformações entre o antes e depois, constata-se que, atualmente, o diagnóstico, o tratamento e a percepção da SOP estão profundamente associados a fatores estéticos. Discute-se, por fim, como este fenômeno está atrelado ao padrão de gênero binário, centrado nas diferenças corporais, produzido historicamente, e, também, como ilustra a ênfase no aprimoramento de si, especialmente no que se refere à sua expressão nos padrões corporais e estéticos.


Abstract This article analyzes the publications of women who suffer from Polycystic Ovary Syndrome (PCOS) in Facebook groups. PCOS is a metabolic syndrome experienced by a vast number of women of childbearing age. Some of its main symptoms are acne, weight gain, and unwanted hair. On the other hand, the treatment focuses on changing the lifestyle associated with diet control and adopting new habits. The analysis of statements and pictures posted by the participants of the groups, which express their before-after transformations, reveals that diagnosis, treatment, and perception of PCOS are currently deeply associated with aesthetic factors. Finally, we discuss how this event is linked to the historically produced binary gender pattern centered on body differences and how it illustrates the emphasis on self-enhancement, especially concerning its expression in body and aesthetic standards.

ABSTRACT

Polycystic ovarian syndrome (PCOS) is the most common heterogenic endocrine illness in women of reproductive age, caused mostly by an excess of androgen and ovarian dysfunction. The present study was carried out to estimate the prevalence of PCOS among Libyan women who attended infertility center Tripoli, Libya, from 2020-2022, evaluate hormonal profile, Body Mass Index, weight and west circumferential before and after treatment and diet management. A longitudinal cross-sectional study conducted in the Tripoli Fertility Center in Tripoli, Libya, the study population targeting output Libyan female patients who presented to the gynecology and obstetrics (OPD) department and therapeutic nutrition department. Data Retrospectively collected from 2020 until 2022 and diagnosed using Rotterdam's criteria. A total of 603 patients visited the gynecology and obstetrics department and the therapeutic nutrition department between January 2020 and December 2022. Out of which 174 women in the PCOS group and 429 in the non-PCOS group. The prevalence of PCOS was 29.56% in 2020, 37.5% in 2021, and 20.27% in 2022. The mean age of PCOS was 34.90 ± 5.5 SD, and all of the PCOS group were married. Worth to mention that all of PCOS cases was insulin resistance type. In terms of weight in the PCOS group, 19.54% were obese BMI >29, 68.96% were morbid obese with BMI >35, and approximately 68.39% of waist circumference measurements were more than 88cm. Hirsutism and oligomenorrhea were the major clinical features, morbid obese seems to be more prevalent in Libyan PCOS patients, low carbohydrate diet and physical activities may play an important role in PCOS management

ABSTRACT

Introducción. Si bien contamos con recomendaciones basadas en la evidencia en contra de realizar tamizaje de cáncer ovárico con ecografía transvaginal debido a que aumenta el riesgo de resultados falsamente positivos y de cascadas diagnósticas, sin disminuir la mortalidad por esta enfermedad, su solicitud en mujeres sanas es frecuente. Sin embargo, no conocemos la magnitud de la implementación de esta práctica, que constituye un cuidado de bajo valor. Objetivo. Documentar el sobreuso de ecografías transvaginales realizadas en forma ambulatoria en un hospital universitario privado de Argentina. Métodos. Estudio de corte transversal de una muestra aleatoria de ecografías realizadas en forma ambulatoria durante 2017 y 2018. Mediante revisión manual de las historias clínicas, la solicitud de cada ecografía fue clasificada como apropiada cuando algún problema clínico justificaba su realización, o inapropiada cuando había sido realizada con fines de control de salud o por una condición clínica sin indicación de seguimiento ecográfico. Resultados. De un total de 1.997 ecografías analizadas, realizadas a 1.954 mujeres adultas (edad promedio 50 años),1.345 (67,4 %; intervalo de confianza [IC] 95 % 65,2 a 69,4) habían sido solicitadas en el contexto de un control de saludo sin un problema asociado en la historia clínica y otras 54 (8,3 %; IC 95 % 6,3 a 10,7), por condiciones de salud para las que no hay recomendaciones de realizar seguimiento ecográfico. Conclusiones. Esta investigación documentó una alta proporción de sobre utilización de la ecografías transvaginales en nuestra institución. Futuras investigaciones permitirán comprender los motivos que impulsan esta práctica y ayudarán a diseñar intervenciones para disminuir estos cuidados de bajo valor. (AU)


Background. Although we have evidence-based recommendations against screening for ovarian cancer with transvaginalultrasound because it increases the risk of false positive results and diagnostic cascades without reducing mortality from this disease, its request in healthy women is frequent. However, we do not know the magnitude of the implementation of this practice, which constitutes low-value care. Objective. To document the overuse of transvaginal ultrasounds performed on an outpatient basis in a private university hospital in Argentina. Methods. Cross-sectional study of a random sample of outpatient ultrasounds performed during 2017 and 2018. Through a manual review of the medical records, the request for each ultrasound was classified as appropriate when a clinical problem justified its performance or inappropriate when it was carried out for health control purposes or for a clinical condition that had no indication for ultrasound follow-up. Results. Of a total of 1997 ultrasounds analyzed, performed on 1954 adult women (average age 50 years), 1,345 (67.4 %;95 % confidence interval [CI] 65.2 to 69.4) had been requested in the context of a health check-up or without a documented problem in the medical history that would support its performance, and another 54 (8.3 %; 95 % CI 6.3 to 10.7), for health conditions for which there are no treatment recommendations to perform ultrasound follow-up. Conclusions. This research documented a high proportion of overuse of transvaginal ultrasound in our institution. Future research will allow us to understand the reasons that drive this practice and will help design interventions to reduce thislow-value care. (AU)

ABSTRACT

ObjectiveTo study the effect of Xihuangwan extract on mitochondrial energy metabolism in ovarian cancer SKOV3 and HEY cells and to explore the underlying mechanism. MethodSKOV3 and HEY cells were cultured in vitro and treated with different concentrations (0, 5, 10, 15, 20 g·L-1) of Xihuangwan extract. Methyl thiazolyl tetrazolium (MTT) was used to examine the viability of SKOV3 and HEY cells treated with Xihuangwan extract. The adenosine-triphosphate (ATP) levels in SKOV3 and HEY cells were measured by kit. Flow cytometry was employed to measure the content of reactive oxygen species (ROS) in cells. Western blot was employed to determine the protein levels of peroxisome proliferator-activated receptor-γ co-activator 1α (PGC1α), transcription factor A, mitochondrial (TFAM), translocase of outer mitochondrial membrane 20 (TOMM20), and aplasia Ras homologue member Ⅰ (ARHⅠ) in SKOV3 and HEY cells. Mito-Tracker Green staining was used to observe the morphological changes of mitochondria in SKOV3 and HEY cells. ResultCompared with blank group, Xihuangwan extract treatment for 24, 48 h inhibited the viability of SKOV3 and HEY cells in a concentration-dependent manner (P<0.05, P<0.01). Compared with blank group, Xihuangwan extract (10, 15, 20 g·L-1) groups presented lowered ATP levels (P<0.05, P<0.01), and the 20 g·L-1 Xihuangwan extract group had lower ATP level than the 10 and 15 g·L-1 Xihuangwan extract groups (P<0.05). Compared with blank group, Xihuangwan extract increased the content of ROS in SKOV3 and HEY cells in a concentration-dependent manner (P<0.05, P<0.01), and the 20 g·L-1 Xihuangwan extract group had higher ROS content than the 10 g·L-1 Xihuangwan extract group (P<0.05). Compared with blank group, Xihuangwan extract up-regulated the expression level of ARHⅠ protein in SKOV3 and HEY cells in a concentration-dependent manner (P<0.01), and the expression levels of ARHⅠ protein was higher in the 20 g·L-1 Xihuangwan extract group than in the 10 and 15 g·L-1 Xihuangwan extract groups (P<0.05). Compared with the blank group, Xihuangwan extract down-regulated the protein levels of PGC1α, TFAM, and TOMM20 in SKOV3 and HEY cells in a concentration-dependent manner (P<0.05, P<0.01), and the protein levels of TFAM and TOMM20 in the HEY cells treated with 20 g·L-1 Xihuangwan extract were lower than those in the HEY cells treated with 10, 15 g·L-1 Xihuangwan extract (P<0.05). Compared with the blank group, 20 g·L-1 Xihuangwan extract decreased the Mito-Tracker fluorescence intensity of SKOV3 and HEY cells (P<0.05). ConclusionXihuangwan can compromise the mitochondrial function of ovarian cancer SKOV3 and HEY cells and reduce cell energy metabolism to inhibit the proliferation of SKOV3 and HEY cells by up-regulating ARHⅠ and inhibiting PGC1α/TFAM signaling axis.

ABSTRACT

Objetivo: Estimar o custo da sequência de tratamento considerando as terapias com niraparibe e bevacizumabe, respectivamente, como terapias de manutenção de 1L e 2L para pacientes com câncer de ovário (CO) epitelial com deficiência de recombinação homóloga (HRD) e BRCA selvagem (BRCAwt) em um horizonte temporal de cinco anos, sob a perspectiva do sistema de saúde suplementar brasileiro. Métodos: Foi desenvolvido um modelo de sobrevida particionado com três transições de estados de saúde, considerando os seguintes regimes em 1L e 2L, respectivamente: carboplatina + paclitaxel seguido de terapia de manutenção com niraparibe; carboplatina + gencitabina + bevacizumabe seguido pela continuação de bevacizumabe. As posologias em bula e as curvas de sobrevida livre de progressão dos respectivos estudos pivotais em cada uma das linhas terapêuticas foram utilizadas na análise, e o custo de tratamento foi calculado a partir da lista oficial de preços de medicamentos da CMED de abril de 2023. Resultados: O custo em 1L e 2L foi de BRL 868.830 e BRL 403.407, totalizando BRL 1.272.237 em um horizonte temporal de cinco anos, com 2,28 e 0,52 anos de vida livre de progressão, respectivamente, na 1L e 2L, com o total de 2,8 anos. Conclusões: O resultado da análise de custo de sequência de tratamento de câncer de ovário HRD/BRCAwt apresentou um custo total estimado de BRL 1.272.237, com 2,8 anos de vida livre de progressão. Essa análise contribui no entendimento dos custos e da eficácia esperada com o uso da terapia de manutenção de niraparibe em 1L e bevacizumabe em 2L em um horizonte temporal de cinco anos.


Objective: To estimate the cost of the treatment sequence, considering the maintenance therapies niraparib and bevacizumab, respectively, as maintenance therapies in 1L and 2L for patients with epithelial ovarian cancer with homologous recombination deficiency (HRD) and BRCA wild-type (BRCAwt) over a 5-year time horizon from the perspective of the Brazilian supplementary health system. Methods: A partitioned survival model was developed with three health state transitions, considering the following regimens in the 1L and 2L, respectively: carboplatin + paclitaxel followed by maintenance therapy with niraparib; carboplatin + gemcitabine + bevacizumab followed by the continuation of bevacizumab. The product's label and progression-free survival curves from the respective pivotal studies in each of the therapeutic lines were used in the analysis and the cost of treatment was calculated using as a reference the official CMED drug price list from April 2023. Results: The cost in 1L and 2L was BRL 868,830 and BRL 403,407, totaling BRL 1,272,237 over a 5-year period, with 2.28 and 0.52 years of progression-free survival, respectively in 1L and 2L, with a total of 2.8 years. Conclusions: The result of the analysis of the cost of the treatment sequence of ovarian cancer HRD/BRCAwt presented an estimated total cost of 1,272,237 with 2.8 year of progression-free survival. This analysis contributes to understand the expected cost and effectiveness with the use of maintenance therapy niraparib in 1L and bevacizumab in 2L over a 5-year time horizon.

ABSTRACT

Abstract Objective To compare the patterns of systemic inflammatory response in women with epithelial ovarian cancer (EOC) or no evidence of malignant disease, as well as to evaluate the profile of systemic inflammatory responses in type-1 and type-2 tumors. This is a non-invasive and indirect way to assess both tumor activity and the role of the inflammatory pattern during pro- and antitumor responses. Materials and Methods We performed a prospective evaluation of 56 patients: 30 women without evidence of malignant disease and 26 women with EOC. The plasma quantification of cytokines, chemokines, and microparticles (MPs) was performed using flow cytometry. Results Plasma levels of proinflammatory cytokines interleukin-12 (IL12), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α) interleukin-1 beta (IL-1β), and interleukin-10 (IL-10), and C-X-C motif chemokine ligand 9 (CXCL-9) and C-X-C motif chemokine ligand 10 (CXCL-10) were significantly higher in patients with EOC than in those in the control group. Plasma levels of cytokine interleukin-17A (IL-17A) and MPs derived from endothelial cells were lower in patients with EOC than in the control group. The frequency of leukocytes and MPs derived from endothelial cells was higher in type-2 tumors than in those without malignancy. We observed an expressive number of inflammatory/regulatory cytokines and chemokines in the cases of EOC, as well as negative and positive correlations involving them, which leads to a higher complexity of these networks. Conclusion The present study showed that, through the development of networks consisting of cytokines, chemokines, and MPs, there is a greater systemic inflammatory response in patients with EOC and a more complex correlation of these biomarkers in type-2 tumors.


Resumo Objetivo Comparar os padrões de resposta inflamatória sistêmica em mulheres com câncer epitelial de ovário (CEO) ou sem evidência de doença maligna, bem como avaliar o perfil de respostas inflamatórias sistêmicas em tumores dos tipos 1 e 2. Esta é uma forma não invasiva e indireta de avaliar tanto a atividade tumoral quanto o papel do padrão inflamatório durante as respostas pró- e antitumorais. Métodos Ao todo, 56 pacientes foram avaliados prospectivamente: 30 mulheres sem evidência de doença maligna e 26 mulheres com CEO. A quantificação plasmática de citocinas, quimiocinas e micropartículas (MPs) foi realizada por citometria de fluxo. Resultados Os níveis plasmáticos das citocinas pró-inflamatórias interleucina-12 (IL12), interleucina-6 (IL-6), fator de necrose tumoral alfa (tumor necrosis factor alpha, TNF-α, em inglês), interleucina-1 beta (IL-1β), e interleucina-10 (IL-10), e da quimiocina de motivo C-X-C 9 (CXCL-9) e da quimiocina de motivo C-X-C 10 (CXCL-10) foram significativamente maiores em pacientes com EOC do que nos controles. Os níveis plasmáticos da citocina interleucina-17A (IL17A) e MPs derivados de células endoteliais foram menores em pacientes com CEO do que no grupo de controle. A frequência de leucócitos e de MPs derivadas de células endoteliais foi maior nos tumores de tipo 2 do que naqueles sem malignidade. Observou-se um número expressivo de citocinas e quimiocinas inflamatórias/regulatórias nos casos de CEO, além de correlações negativas e positivas entre elas, o que leva a uma maior complexidade dessas redes. Conclusão Este estudo mostrou que, por meio da construção de redes compostas por citocinas, quimiocinas e MPs, há maior resposta inflamatória sistêmica em pacientes com CEO e correlação mais complexa desses biomarcadores em tumores de tipo 2.

ABSTRACT

Existem poucos dados na literatura sobre os resultados obstétricos e oncológicos de adolescentes com tumores borderline de ovário em estádio avançado trata- das com cirurgia preservadora da fertilidade. Uma adolescente de 15 anos com diagnóstico de tumor borderline de ovário estádio IIIc foi inicialmente tratada com tumorectomia ovariana bilateral e quimioterapia adjuvante com esquema de platina/taxano (seis ciclos). Durante o seguimento, foi submetida a outras três tumorectomias devido a tumor borderline de ovário (duas vezes) e cistadenoma ovariano (uma vez). Outra recidiva de tumor borderline de ovário ocorreu seis anos após o diagnóstico inicial, quando ela estava grávida; foi tratada com tumorecto- mia realizada durante a cesariana. Em sua última consulta ambulatorial, a mulher de 27 anos não apresentava evidência da doença e tinha um filho saudável. Mesmo em estádio avançado, a cirurgia de preservação da fertilidade foi segura e factível nessa paciente com tumor borderline de ovário.


There are few data in the literature regarding obstetric and oncological outcomes of adolescents with advanced-stage borderline ovarian tumors treated with fertility spa- ring surgery. A 15 years old adolescent who was diagnosed with a stage IIIc borderline ovarian tumor, was treated with bilateral ovarian tumorectomies and adjuvant chemotherapy with platinum/taxane regimen (six cycles). During follow up she was submitted to other three tumorectomies due to borderline ovarian tumor(twice) and ovarian cysta- denoma (once). Another borderline ovarian tumorrecurren- ce occurred six years after initial diagnosis, when she was pregnant; treated with tumorectomy performed during ce- sarean section. At her last outpatient visit, the 27-year-old woman had no evidence of disease and a had healthy child. Even at an advanced stage, fertility sparing surgery was safe and feasible in this patient with borderline ovarian tumor.

ABSTRACT

O objetivo deste estudo é descrever o caso de mulher com síndrome de Meigs e apresentar a revisão narrativa sobre o tema. Paciente do sexo feminino, 30 anos, nulípara, encaminhada ao hospital por massa anexial e história prévia de drenagem de derrame pleural. Evoluiu com instabilidade hemodinâmica por derrame pleural hipertensivo à direita, sendo submetida a drenagem torácica, com citologia do líquido negativa. Após, foi submetida a laparotomia: realizada salpingo-ooforectomia esquerda. A congelação e a análise histopatológica diagnosticaram fibroma ovariano. A citologia ascítica foi negativa. CA-125 elevado, presença de derrames cavitários e exame de imagem suspeito podem mimetizar um cenário de neoplasia maligna de ovário em estágio avançado. Entretanto, na síndrome de Meigs clássica, o tratamento é cirúrgico, sendo o diagnóstico obtido por meio da análise histopatológica do tumor ovariano. O manejo da síndrome de Meigs clássica é cirúrgico e, após a remoção do tumor, o derrame pleural e a ascite desaparecem.


To describe a case of Meigs syndrome and present a narrative review of the condition. Female patient, 30 years old, nulliparous, referred to the hospital due to an adnexal mass and a previous drainage of pleural effusion. She developed hemodynamic instability due to a hypertensive right pleural effusion being submitted to chest drainage, with negative cytology of the fluid. She underwent laparotomy: Left salpingo-oophorectomy was performed and frozen section and histopathological analysis diagnosed an ovarian fibroma. Ascites cytology was negative. Elevated CA-125, presence of cavitary effusions, suspicious imaging exam can mimic a scenario of ovarian cancer at an advanced stage. However, in classical Meigs syndrome, treatment is surgical, and the diagnosis is obtained through histopathological analysis of the ovarian tumor. Classical Meigs syndrome' management is surgical. After tumor removal, pleural effusion and ascites resolve.
