Factors in malignant transformation of ovarian endometriosis: A narrative review

Endometriosis is a common estrogen-dependent inflammatory disease with a chronic course and a tendency to recur. The association between endometriosis and cancer has been studied for several years. Numerous reports have demonstrated a strong association between specific ovarian malignancies and endometriotic lesions. Atypical endometriosis has been widely described as a malignant precursor to ovarian epithelial tumors, particularly clear cell carcinomas and endometrioid carcinomas. These histological types associated with endometriosis develop predominantly in the ovary rather than in extragonadal sites. The detailed molecular mechanism of etiology remains unclear. Recent studies have analyzed the genetic and molecular mechanisms involved in endometriosis-associated ovarian cancer. A critical role appears to be played by a carcinogenic model based on iron-induced oxidative stress, which is typical of the endometriosis microenvironment. It has been hypothesized that trans-tubal reflux of blood, endometrial cells and associated iron-induced oxidative stress underlie the development of endometriosis-associated ovarian cancer. However, the multifactorial mechanisms of this malignant transformation are not fully understood. The aim of this review is to summaries the current epidemiological, histopathological, genetic and molecular findings in the progression of endometriosis-associated ovarian cancer.

Review of menopausal hormone therapy with estradiol and progesterone versus other estrogens and progestins

Serum HSP70 level in patients with endometrial cancer with and without diabetes

Diabetes mellitus (DM) is associated with an increased risk of endometrial carcinoma (EC). Heat shock proteins have a role in the modulation of both diseases. The aim of this study was to investigate extracellular HSP70 (eHSP70) level alternations in patients with two different types of EC (endometrioid and non-endometrioid) with and without type 2 diabetes. In a case-control study, 88 participants were enrolled in four groups including: 18 EC patients with DM, 19 EC patients without DM, 29 patients with DM, and 22 healthy individuals. Blood samples were taken before surgery in cancer patients. Estradiol, eHSP70, sex hormone-binding globulin (SHBG), FBS, and HbA1c were assessed. Serum HSP70 level was higher in patients with diabetes (52.24 ± 14.2 ng/ml) compared to healthy controls (39.04 ± 6.96) (

Awareness, burden and treatment of uterine fibroids: a web-based Italian survey

Uterine fibroids (UFs) are the most common benign tumors in women of reproductive age and one of the leading causes of hysterectomy in Italy. This survey aimed to report how Italian women perceive and approach UFs, in order to raise healthcare professionals (HCPs)', institutions' and women's awareness of UFs and their treatment options. 1508 Italian women aged 30-50 years completed a web-based survey, answering a structured questionnaire focused on UF prevalence, symptomatology and impact, management and awareness. UF self-reported prevalence was 28.8%. Most UF-diagnosed women had symptom(s) before diagnosis (79.0%), and more than a half of UF-diagnosed participants were symptomatic post-diagnosis (55.8%). The most common symptoms after diagnosis were heavy menstrual bleeding (73.1%), dysmenorrhea (50.4%) and pelvic pain (36.8%). UFs negatively affected the quality of life of most symptomatic women, as well as sexuality and employment. Private gynecologists were the key reference HCPs for consultation and UF diagnosis. The most common UF treatments for symptomatic women were surgery (49.2%), followed by oral contraceptives (39.3%). Surgery was also performed for 22.9% of asymptomatic participants. UF-diagnosed participants were not involved in therapeutic choices in 37.6% of cases. Women's knowledge about UFs was mostly superficial (58.7% of all participants), with gynecologists and family/friends as main information sources. Patient-physician communication was rather unsatisfactory, especially about UF therapeutic options and disease impact on sexuality, fertility and lifestyle. This survey highlights that there is still a need to promote patient's knowledge about UFs and empowerment in treatment decision.

High level of visfatin and the activation of Akt and ERK1/2 signaling pathways are associated with endometrium malignant transformation in polycystic ovary syndrome

This study aimed to assess the clinicopathological significance of serum levels and endometrium tissue expression of visfatin in polycystic ovary syndrome (PCOS) patients. A total of 80 PCOS patients and 80 matching controls were included in this study. We analyzed the relationship between the expression of visfatin in endometrium and clinicopathological characteristics in PCOS patients. The correlation between the expression of visfatin and p-Akt, Akt, p-ERK1/2, and ERK1/2 in PCOS tissues was evaluated as well. Visfatin expression in PCOS endometrial tissues were significantly higher than those in controls (

Adolescent ovarian thecoma presenting as progressive hyperandrogenism: case report and review of the literature

Hyperandrogenism is frequent and under investigated in adolescent girls. A 15-year-6-month-old French girl presented with oligomenorrhea and slowly progressing virilization 2 years post-menarche. Medical history revealed prenatal pesticide exposure through maternal professional activity and recurrent premature thelarche. Severe hirsutism, mild facial acne and clitoromegaly were noted. Serum androgens (testosterone: 94 ng/dL, 4-androstenedione: 8.23 ng/mL) were high and non-classic 21-hydroxylase deficiency was excluded. Pelvic ultrasonography showed a left ovarian mass, confirmed by computed tomography scan. Tumor markers were negative. Laparoscopic surgery was performed. The pathological diagnosis was benign luteinized thecoma. Postoperatively, the menstrual cycle and serum androgens became normal and hirsutism slowly improved. Hyperandrogenism 2 years after menarche should be systematically investigated, even if slowly progressive, since it may be a symptom of a rare virilizing ovarian tumor, like thecoma.

A case series of patients with gonadal dysgenesis-associated mixed malignant ovarian germ cell tumor

Laparoscopic treatment of ovarian granulosa cells tumor developed in the pelvic anterior preperitoneal space 20 years after laparotomic salpingo-oophorectomy: case report and review of literature

Granulosa cells (GC) tumors are rare tumors which account for approximately 2-3% of all ovarian malignancies with a favorable prognosis. We report a case of a 54-year-old postmenopausal woman who developed an ovarian GC tumor in the pelvic anterior preperitoneal space 20 years after laparotomic salpingo-oophorectomy due to small part of the cyst could drop or remain entrapped into the abdominal wound during the closure of laparotomy 20 years before. Then, the patient underwent a second laparoscopic procedure with peritoneal washing, a type A radical hysterectomy, omentectomy, appendectomy, and pelvic and para-aortic lymphadenectomy. This rare case of ovarian GC tumor developing in the site of previous laparotomy demonstrates the importance of a correct and clean surgical procedure to avoid the risk of leaving even small portions of the cyst exposing the patients to either the risk of malignancy or additional surgical procedures.

Papillary thyroid carcinoma in Struma Ovarii

Struma Ovarii is one of the types of mature teratoma, with predominant thyroid tissue (>50%). It occurs in 1% of all cases of ovarian tumors and in 2.7% of dermoid tumors. There are no specific clinical, radiological or serum markers for this rare pathology. Rarely it may be accompanied by ascites and the increased level of CA-125. In general Stuma Ovarii is clinically defined as an ovarian malignancy. It is diagnosed only by histopathological examination of the surgical material. Diagnosis of Struma Ovarii dictates the need for advanced research of the thyroid. Struma Ovarii is mostly benign. Its malignant transformation occurs in only 5% of all cases, That leads to further management planning analogous to the treatment of thyroid cancer. The case of malignant Struma Ovarii of the 50-year-old woman, which led to total thyroidectomy and radioactive iodine therapy - is described.

The expression levels and clinical significance of MFG-E8 and CD133 in epithelial ovarian cancer

The aim of our study was to test whether there is an association between high expression of milk fat globule EGF factor 8 (MFG-E8) and CD133 presence or clinical outcomes of patients with epithelial ovarian cancer (EOC). MFG-E8 and CD133 expression levels were analyzed by immunohistochemistry in 88 EOC tumor specimens. High expression of MFG-E8 directly and significantly correlated with the presence of CD133 immunostaining (

Ovarian steroid cell tumor as an example of severe hyperandrogenism in 45-year-old woman

Approximately, 5% of ovarian tumors have hormonal activity. Steroid cell tumors (SCTs) represent about 0.1% of all ovarian tumors. They cause hyperandrogenism associated with typical virilization. In this case report, we present 45-year-old women with unmalignant ovarian SCT-producing androgens which cause severe virilization and secondary amenorrhea lasting two years. Transvaginal ultrasound, computed tomography of adrenal glands, magnetic resonance imaging of small pelvis, laboratory tests (including serum concentration of FSH, LH, testosterone (T), androstenedione (A), dehydroepiandrosterone sulfate (DHEA-S), as well as ROMA index) were performed. During hormonal evaluation, elevated concentrations of serum T - on admission 1.72 ng/ml and one month later 3.75 ng/ml (normal range 0.08-0.82 ng/ml) and A - 24.90 ng/ml (normal range 0.40-3.40 ng/ml) were found. The ROMA index was within the normal range. Enlargement of the left ovary by solid mass 56 × 43 mm was found during ultrasound examination. Based on small pelvis MRI scan and hormonal finding, patient was qualified for laparotomy. During this procedure, the left salpingo-oophorectomy with removal of the tumor was performed. The histopathological examination identified SCT. During follow-up examination, one day after surgery, we found serum testosterone levels within normal ranges - 0.74 ng/ml (normal range 0.08-0.82 ng/ml). This case shows that hormone-producing ovarian tumors are rare but very important clinical causes of severe hyperandrogenism.

Androgen-secreting adult granulosa cell tumor in a woman with polycystic ovary syndrome: a case report

Endometriomas with low-risk malignancy potential in ultrasonography with high human epididymis protein 4 and risk of ovarian malignancy algorithm: a cases series

Endometriosis is an estrogen-dependent disease that affects 5 to 15% of women of reproductive age. Data from large-cohort and case-control studies indicate an increased risk for ovarian cancers in women with endometrioma. Recently, as an ovarian cancer biomarker, human epididymal secretory protein E4 (HE4) has been increasingly investigated in the differentiating of endometrioma from ovary malignancy and in confirming the benign structure of the endometrioma. This case series study describes women who underwent surgery due to increased serum HE4 levels and higher Risk of Ovarian Malignancy Algorithm (ROMA) index, in whom the final pathology was reported as benign, although, ultrasonography and magnetic resonance imaging (MRI) findings showed features of "typical" endometrioma.

Hyperthyroidism associated with struma ovarii – a case report and review of literature

Hyperthyroidism is a state characterized by elevated serum level of thyroid hormones: thyroxine (T4) and triiodothyronine (T3). This is mainly related to the condition and functioning of the thyroid gland. In 60-80% of cases elevation of these hormones are caused by Grave's disease. Thyrotoxicosis is an extreme presentation of hyperthyroidism which can, in rare cases, be caused by excessive synthesis of thyroxine by tumor cells. Struma ovarii is a rare ovarian teratoma composed of thyroid tissue in more than 50%. To present a case of a 30-year-old female patient with a past history of Grave's disease treated by strumectomy 7 years prior; now presenting for the assessment of secondary amenorrhea. Pelvic ultrasound revealed bilateral solid tumors on the left and right ovary, respectively measuring 5 cm and 6 cm in diameter. Her clinical presentation was suggestive of overt hyperthyroidism, and she presented with a significantly elevated CA-125 (152.7 U/mL). The patient subsequently underwent a bilateral oophorectomy in which both masses were excised and histopathological examination confirmed teratoma maturum cysticum. Struma ovarii was noted as a component of the left ovary teratoma. Establishing a proper diagnosis of hyperthyroidism and elucidating its origin is often challenging. Struma ovarii is a rare cause of hyperthyroidism but should always be considered in case of treatment resistant hyperthyroidism. This case-report lends itself as an example of the value in maintaining gynecological-endocrinological knowledge in the setting if clinical gynecology.

Surgical management of ovarian teratomas in childhood: a multicentric study on 110 cases and a literature review

To compare a multicentric surgical experience on ovarian teratomas in childhood with the current management trends. A retrospective multicentric pediatric ovarian teratomas surgically treated between January 2000 and August 2020 at four Italian institutions. PubMed database was used to search for Reviews and Systematic Reviews published between January 2010 and August 2020: 15 manuscripts reported 3633 ovarian neoplasms in pediatric age, 1219 (33,5%) of which were ovarian teratomas. A hundred-ten patients with a mean age at diagnosis of 11.8 years were enrolled. Mature cystic teratomas accounted for the 90% of the masses. At surgery, 78 were oophorectomies and 32 were ovary sparing surgeries. Laparoscopy occurred in 16.3% of the surgeries.As regarding the current management trends, the mean age at diagnosis was 11.9 years and 80.5% of the cases were represented by mature teratomas. Of 430 procedures, 331 were oophorectomies while 99 were ovary sparing surgeries and laparoscopy was performed in 23.8% of cases. Ovary-sparing surgery with laparoscopic approach is increasingly offered as standard treatment for benign masses that fit the criteria for mature teratomas, in the attempt to achieve the best compromise between the preservation of fertility and the prevention of recurrences. Awareness should be raised among pediatric surgeons to reduce unnecessary radical surgery.

First case report of papillary thyroid carcinoma arising within a functional teratoma in Graves’ disease patient

Mature cystic teratoma is the most common kind of ovarian germ tumor. However, malignant transformation is uncommon, differentiated thyroid carcinoma is even rare. Hyperthyroidism due to coexistence of Graves' disease (GD) and struma ovarii has been reported. Functional teratoma with papillary thyroid carcinoma (PTC) in GD case has never been reported in literature. A 48-year-old woman with GD for 4 years, who visited our hospital with complaints of severe abdominal pain for 1 day. Computed tomography of the abdominal revealed a large fat-containing lesion with dense calcification, measured 8.6 × 7.2 cm in size. Laparotomy right total oophorectomy was performed, and a huge gangrenous right ovary was noted during exploration. The final pathological diagnosis was teratoma with PTC change at right ovary. We performed thyroglobulin, TTF-1 and CK19 staining in the teratoma, the results were positive, suggesting the thyroid-hormone secretion in the PTC tissue. After resection of the ovarian lesion, euthyroidism was achieved. Adjuvant thyroidectomy is not performed for no evidence of thyroid lesion or distant metastases. No GD recurrence in the 2 years after operation. The patient also does not manifest any gynecological disease symptoms, whereas the other ovary, in the follow-up ultrasound examinations, shows normal size and echo structure. PTC can arise within ovarian teratoma and may have thyroid hormone production. Surgeries of unilateral oophorectomy or cystectomy are a reasonable treatment, and follow-up of thyroid image and data is necessary.

Ovarian steroids and cancer: news on the breast, questions on the reproductive tract

Dexamethasone suppression test versus selective ovarian and adrenal vein catheterization in identifying virilizing tumors in postmenopausal hyperandrogenism – a systematic review and meta-analysis

The diagnostic accuracy of tests in identifying virilizing tumors in postmenopausal hyperandrogenism is limited. This systematic review compares the dexamethasone suppression test against selective ovarian and adrenal vein sampling of androgens in distinguishing neoplastic from non-neoplastic causes of postmenopausal hyperandrogenism. Diagnostic test accuracy studies on these index tests in postmenopausal women were selected based on pre-established criteria. The true positive, false positive, false negative, and true negative values were extracted and meta-analysis was conducted using the hierarchical summary receiver operator characteristics curve method. The summary sensitivity of the dexamethasone suppression test is 100% (95% CI 0-100%) and that for selective venous sampling is 100% (95% CI 0-100%). The summary specificity of the dexamethasone suppression test is 89.2% (95% CI 85.3-92.2%) and that for selective venous sampling is 100% (95% CI 0.3-100%). There is limited evidence for the use of dexamethasone suppression test or selective venous sampling in identifying virilizing tumors in postmenopausal hyperandrogenism.

Fertility preservation in ovarian cancer patients

Ovarian cancer is more frequent in post-menopausal women, however it can also occur in young premenopausal women. After diagnosis and cancer staging, health care providers should address the possibility of infertility and might offer fertility preservation options. Chemotherapy, frequently used when treating ovarian cancer, has proven to cause extensive ovarian damage. Standard surgery may be aggressive and the recurrence risk may not be relevant enough to opt for these approaches. Fertility sparing surgery has been progressively accepted and many alternative surgical approaches have proven to be successful in both cancer treatment, fertility preservation and low recurrence rates. Though there are several techniques available for fertility preservation in cancer patients, when dealing with ovarian cancer patients, oocyte and embryo cryopreservation are the only suitable. Ovarian tissue cryopreservation has been largely studied, but no data on ovarian cancer patients exist, due to the risk of reimplanting cancer cells.

From diagnosis to treatment of androgen-secreting ovarian tumors: a practical approach

About 5% of all ovarian tumors develop some form of hormonal activity. Only 1% of ovarian tumors will secrete androgens causing clinical hyperandrogenism. Most androgen-secreting neoplasms (ASN) derive from sex cord or stroma cells of the ovary and may affect both premenopausal and postmenopausal women. Typically, a patient will present reporting symptoms of rapidly increasing hyperandrogenization such as: hirsutism, acne, frontal/male pattern balding, and in severe cases even virilization. Sertoli-Leydig Cell Tumors are the most frequent ASN and constitute about 0.5% of all ovarian neoplasms. Typically affecting women under 30 years of age, these tumors are usually unilateral and benign. They are also the most common tumor in postmenopausal women suffering with hyperandrogenism. Other tumors originating from the sex-cord stroma are also known to develop in this population, but the incidence of these is much lower. Approaching suspected hyperandrogenemia and its related symptoms in a clinical setting can be a significant diagnostic challenge. When evaluating a patient for hyperandrogenism, it is important to assess the severity of symptoms but most of all it is critical to assess the time of onset and dynamics of symptom progression. Diagnostic tools including laboratory tests and imaging studies should also be engaged. When deriving a differential diagnosis for androgen-secreting ovarian tumors, adrenal gland tumors should be considered as well as typical endocrine pathologies including polycystic ovary syndrome, congenital adrenal hyperplasia, Cushing's disease, and acromegaly. Treatment options for an androgen-secreting ovarian tumors is mainly surgical, but in exceptional cases can involve pharmacotherapy alone.

Hyperestrogenemia resulting from a granulosa cell tumor and causing pulmonary thromboembolism: a case report

Estrogen modulates platelet activation and aggregation, and it increases the levels of the von Willebrand factor, factors II, VII, VIII, and X, and of fibrinogen, all of which increase the risk for thromboembolism. We report the case of a 59-year-old woman, postmenopausal for 4 years, not using hormone replacement therapy, who was admitted into the emergency room with shortness of breath and increased abdominal volume. After physical examination and imaging and biochemical tests, she was diagnosed with pulmonary thromboembolism and a large left adnexal tumor. The patient was promptly received full anticoagulation therapy for the pulmonary thromboembolism. High levels of estradiol (810.4 pg/mL), anti-Mullerian hormone (16.39 ng/mL), inhibin (11250 pg/mL), and suppressed FSH (<0.16 IU/L) led to a suspicion of granulosa-cell tumor. After clinical stabilization, she underwent to an exploratory laparotomy with total hysterectomy and bilateral adnexectomy to treat the pelvic tumor. Pathologic report confirmed a granulosa-cell tumor.

Is hemoglobin A1c valuable for predicting concurrent endometrial cancer in diabetic women with endometrial intraepithelial neoplasia?

The purpose of this study was to determine the predictive value of preoperative hemoglobin A1c (HgA1c) level for endometrial cancer in diabetic women with endometrial intraepithelial neoplasia (EIN). Six hundred patients with EIN were retrospectively studied in a tertiary referral center in Turkey between January 2014 and December 2021. One hundred and thirteen diabetic patients with EIN who met the inclusion criteria were enrolled in the study and divided into three groups according to the final pathological results: Group 1 with benign findings ( Mean preoperative HgA1c levels were different among three groups (5.41 ± 0.64, 6.01 ± 0.72, 6.65 ± 1.15, HgA1c could be used in prediction of endometrial cancer. The optimal cutoff value determined in our study could be considered in predicting endometrial cancer in diabetic women with EIN.

Progestin or anti-estrogen treatment for endometrial cancer: choosing the best option for selected patients

Asymptomatic postmenopausal women: what are the risk factors for endometrial malignancies? A multicentric retrospective study

To evaluate the prevalence and risk factors for endometrial malignancies in asymptomatic postmenopausal women. Multicentric retrospective analytical study in two Brazilian Reference Centers. All women without postmenopausal bleeding who were submitted to hysteroscopy with biopsy were included (1665). Excluded women without anatomopathological results (625) and whose medical records were incomplete (37). The variables analyzed were age; parity; body mass index; duration of menopausal status; systemic arterial hypertension; diabetes mellitus; use of hormone replacement therapy; use of tamoxifen; duration of use of tamoxifen; endometrial thickness and biopsy results. The frequency of endometrial malignancies in asymptomatic postmenopausal women was 2.39%. Endometrial thickness ≥8 mm increased the chance of endometrial malignancies, even more, with an endometrial thickness ≥12.55 mm the chance of endometrial malignancies increased by 4.68 times ( The prevalence of endometrial malignancies was low and the only risk factor for endometrial malignancies in asymptomatic postmenopausal women was endometrial thickness.

The polycystic ovary syndrome and gynecological cancer risk

This review updates the knowledge regarding the association between the polycystic ovary syndrome (PCOS) and the risk of gynecological cancer. We performed a literature review of clinical and epidemiological studies concerning PCOS and the risk of breast, endometrial and ovarian cancer after selecting information by quality of scientific methodology. It was found that evidence does not support a link between PCOS and breast cancer risk. There is an increased risk of endometrial cancer, while data concerning ovarian cancer are contradictory. Regarding PCOS and its association to cervical, fallopian tube, and vulvar cancer, the quality of evidence is heterogeneous. In conclusion, women with PCOS should be screened for endometrial cancer and more research is warranted to determine in this population the true risk of developing other gynecological cancers such as breast and ovarian.

Benign polypoid adenomyomatous endometrium associated with hpt-JT syndrome: a case report

Hyperparathyroidism-jaw tumor (HPT-JT) is an autosomal dominant disorder responsible for benign and/or malignant tumors. Affected women often present life-threatening menorrhagia that leads to the identification of uterine tumors, and experience miscarriages and infertility. Overall though, fewer data concerning gynecological pathologies related to HPT-JT syndrome are available. We report the case of a 32-year-old woman with HPT-JT syndrome, referred for recurrent vaginal bleeding, with a history of repeated endometrial polyps and infertility. We also review the literature that explores medical options for these women.

Multicentric adrenocorticotropic hormone -producing steroid cell tumor of the fallopian tube &amp; broad ligament in a 15 year old girl

Steroid cell tumors occur usually in the ovaries with very few reported cases of extra-ovarian origin. Our patient was a fifteen year old female, complaining from secondary amenorrhea and voice deepening. Values of serum cortisol, DHEA, FSH & LH were normal. Serum Testosterone was elevated while ACTH-pm was markedly elevated. MRI described bilateral solid para-ovarian masses. Exploration revealed two bilateral tubal extraluminal cysts & a right broad ligament cyst which were all excised. Pathological examination led to the diagnosis of steroid cell tumor. Serum testosterone & ACTH returned to normal levels after surgery with subsequent regression of the virilizing symptoms. We can conclude that extra-ovarian steroid cell tumors are extremely rare. They are usually presented with virilizing symptoms and hormonal abnormalities. Surgery is the main line of treatment.

Multicenter, prospective, single-arm clinical study to investigate the efficacy and safety of Zoladex (Goserelin acetate) 10.8 mg prior to surgery in Chinese premenopausal women with symptomatic uterine fibroids

To assess the effect and safety of Zoladex (Goserelin acetate) 10.8 mg in patients with uterine fibroids. Fifty-three patients received Goserelin acetate 10.8 mg once and surgery was conducted at 12 weeks ± 7 days after drug injection. All assessments form baseline to week12/before surgery were carried out: fibroids volume, uterine volume, serum hormone (E2, FSH, LH), hemoglobin concentration, uterine arterial resistance index (UA-RI), fibroid arterial RI (FA-RI) and improvements of symptoms (Uterine Fibroid Symptom and Quality of Life (UFS-QOL) and Health-Related Quality of Life (HRQL) scores). Adverse events (AEs) were recorded to evaluate the safety. After 12 weeks of treatment, the volume of uterine fibroids was significantly smaller than before (249.19 ± 297.04 vs. 195.77 ± 418.27 cm3, Goserelin acetate 10.8 mg pretreatment can effectively reduce the volume of uterine fibroids and uterus, lower estrogen levels and improve anemia symptoms. It could also improve the quality of life of patients, showing good safety and tolerance. This pretreatment was effective, safe, and generally well tolerated.

Ovarian steroid cell tumor (not otherwise specified) with subsequent spontaneous pregnancy after tumor removal: a case report and literature review

Steroid cell tumors not otherwise specified are rare sex cord-stromal tumors of the ovary that may produce various steroids and are associated with hirsutism and virilization. We report a rare case of ovarian steroid cell tumor with subsequent spontaneous pregnancy after tumor removal. A 31-year-old woman presented with secondary amenorrhea, hirsutism, and inability to conceive. Clinical and diagnostic evaluations revealed a left adnexal mass and elevated serum total testosterone and 17α-hydroxyprogesterone levels. She underwent a left salpingo-oophorectomy, and histopathological examination confirmed the diagnosis of a steroid cell tumor not otherwise specified. Her serum total testosterone and 17α-hydroxyprogesterone normalized one month after surgery. Her menses resumed spontaneously one month after the operation. She spontaneously conceived 12 months after the surgery. The patient had an uncomplicated pregnancy and delivered a healthy male infant. In addition, we reviewed the literature on steroid cell tumors not otherwise specified with subsequent spontaneous pregnancies after surgery and data regarding pregnancy outcomes.

Estrogen receptor-related receptor γ uppresses hypoxia-induced angiogenesis by regulating VEGFA in endometrial cancer

Estrogen receptor-related receptor γ (ERRγ), is implicated in cancer cell proliferation and metastasis. The function of ERRγ in tumor angiogenesis, however, is to be revealed. This study was designed to elaborate the regulatory effect of ERRγ on angiogenesis in endometrial cancer (EC). Immunohistochemistry (IHC) was adopted to determine the protein expression of ERRγ, VEGFA, CD31 and hypoxia-inducible factor-1 (HIF-1) in tumor tissues. HEC-1A cells stably expressing ERRγ were established bytransfection, and then an endothelial cell tube formation assay was performed. CCK-8 assay was employed for cell viability, and wound healing assay for cell migration ability. Besides, western blot, ELISA and qRT-PCR were used to examine the VEGFA expression. After hypoxia treatment of ERRγ overexpressing HEC-1A cells, the ERRγ expression and VEGFA expression were determined by western blot. Finally, EC xenografts in nude mice were constructed by subcutaneous injection of ERRγ stably expressing HEC-1A cells and control HEC-1A cells. IHC results revealed a negative correlation between the expression of ERRγ and VEGFA in EC tissues. ERRγ overexpression significantly decreased the level of HIF-1 in tumor tissue of nude mice. ERRγ overexpression down-regulated inhibited angiogenesis capability and inhibited the proliferation and migration of HEC-1A cells. Furthermore, ERRγ expression was suppressed under the condition of hypoxia while restoration of ERRγ partially inhibited hypoxia-induced VEGFA expression in HEC-1A cells. ERRγ is an angiogenesis suppressor and involved in hypoxia-induced VEGFA expression in EC. Hence, ERRγ might be a promising antiangiogenic target for human EC.

Occult symptomatic bilateral pure Leydig cell tumors in a postmenopausal woman: a case report

Pure Leydig cell tumors (LCTs) represent 0.1% of ovarian masses. Postmenopausal patients typically present with virilization. Although LCTs can be challenging to locate on conventional imaging, positron emission tomography (PET) has been demonstrated to be effective. A 64-year-old postmenopausal woman presented with alopecia, facial hirsutism, and clitoromegaly. Laboratory findings included elevated testosterone and androstenedione. Ultrasound, computed tomography, and magnetic resonance imaging showed no adnexal masses. PET did not demonstrate ovarian fludeoxyglucose-avidity. Histopathology after bilateral salpingo-oophorectomy revealed bilateral Leydig cell tumors. Her testosterone normalized 2 weeks postoperatively. We describe the occult, symptomatic, bilateral ovarian Leydig cell tumors, an occurrence that has not been described in the literature. Virilizing tumors must be considered in patients with evidence of hyperandrogenism, even without pelvic masses on imaging.

A case of excision of ovarian torsion necrosis due to luteoma in a female who conceived a twin pregnancy through in vitro fertilization misdiagnosed with acute appendicitis

The aim of this study was to describe a case of ovarian torsion necrosis due to delayed treatment of luteoma in a woman with IVF twin pregnancy who was misdiagnosed with acute appendicitis. We summarized the clinical manifestations and diagnosis of luteoma in a woman with IVF twin pregnancy and reviewed the relevant literature. We report the case of a 34-year-old Asian female who became pregnant through

Knockdown of SNHG1 inhibits cervical cancer growth through sponging miR-194 to regulate HCCR

To investigate the mechanism of small nucleolar RNA host gene 1 (SNHG1) in cervical cancer (CC).

Case report: Ovarian steroid cell tumor with CA72-4 elevated

Ovarian steroid cell tumor, not otherwise specified (SCT-NOS), is a rare subtype of sex cord-stromal tumor, characterized by hirsutism and virilization. There are, however, few tumor markers reported in the tumor. The following is a case report. Six years ago, the patient underwent a left adnexectomy after being diagnosed with a yolk sac tumor. Her serum CA72-4 levels were significantly elevated when she was diagnosed with SCT-NOS. She suffered from hirsutism and oligomenorrhea with long menstrual cycles. SCT-NOS was confirmed by her histopathological examination. When the tumor was diagnosed, serum CA72-4 levels were elevated. Following tumor resection, serum CA72-4 levels returned to the average reference interval. Whole-exome sequencing (WES) was utilized to identify ten mutations in MKI67, TICAM1, CHD3, ARID5B, ERBB4, POLD1, FZR1, MTCP1, TBX3, and CLTC genes.

Interaction between XRCC2 gene polymorphism and abdominal obesity on risk of endometrial carcinoma

The aim of this study was to investigate the impact of three single nucleotide polymorphisms (SNPs) within X-Ray Repair Cross Complementary Group 2 (XRCC2) gene and additional gene- abdominal obesity (AO) interaction with endometrial carcinoma (EC) risk. Hardy-Weinberg equilibrium was tested for all participants by using SNPstats (online software: http://bioinfo.iconcologia.net/SNPstats). The best SNP-SNP and gene-AO interaction combination among three SNPs within XRCC2 gene and AO was screened using generalized multifactor dimensionality reduction (GMDR). We employed the logistic regression analysis showed that rs718282-T allele is associated with increased EC risk, adjusted ORs (95%CI) were 1.67 (1.23-2.04). However, we did not find statistical association between rs3218536, and rs3218384 and EC susceptibility. GMDR analysis was used for SNP-SNP- and gene-abdominal obesity analysis. The cross-validation consistency and the testing accuracy for the interaction were calculated. The two-locus model between rs718282 and AO had a testing accuracy of 60.11%, which was significant at the Both the rs718282- T allele, and its interaction with AO were associated with increased EC risk.

Estrogen promotes the proliferation and migration of endometrial cancer cells by upregulating the expression of lncRNA HOTAIR

Estrogen (E2) is the main contributor to the progression of endometrial cancer (EC). The long noncoding RNA HOX antisense intergenic RNA (HOTAIR) is emerging as a new regulator in several cancer types. This study aimed to investigate the role of HOTAIR in EC development and identify the underlying molecular mechanisms. HOTAIR expression levels in human EC tissues and the corresponding adjacent tissues and human EC Ishikawa cells were determined by quantitative PCR. Ishikawa cells were treated with E2 or estrogen receptor (ER) inhibitor ICI182780, transfected with siHOTAIR oligo, or infected with lentivirus expressing shHOTAIR/shNC, alone or in combinations. The protein expression of polycomb repressive complex 2 (PRC2) was evaluated by western blotting, and cell migration was measured by transwell assays. A xenograft tumorigenic model was established by inoculating control or stable shHOTAIR-infected Ishikawa cells into nude mice and implanting 17β-estradiol release pellets. HOTAIR expression was significantly elevated in human EC tissues. E2 exposure markedly increased HOTAIR levels in Ishikawa cells. Notably, E2 increased the protein expression of PRC2 and promoted EC cell migration, which were dependent on HOTAIR expression, as HOTAIR knockdown abolished these effects of E2. Similarly, E2 promoted the Human EC tissues highly express HOTAIR, and E2-induced EC progression depends on HOTAIR expression. This work suggests that the E2-HOTAIR axis is a potential therapeutic target in EC therapy.

Should body mass index replace age to drive the decision for endometrial sampling in premenopausal women with abnormal uterine bleeding?

This study aimed to evaluate risk factors for endometrial intraepithelial neoplasia/malignancy in premenopausal women with abnormal uterine bleeding or oligomenorrhea. Specifically, we aimed to elucidate whether body mass index (BMI) or age confers a higher risk. A retrospective cohort study was performed at a large academic center examining risk factors for endometrial hyperplasia/malignancy in premenopausal women undergoing endometrial sampling. Of the 4170 women ages 18-51 who underwent endometrial sampling from 1987 to 2019, 77 (1.85%) were found to have endometrial intraepithelial neoplasia or malignancy. Clinical predictors of EIN/malignancy in this population included obesity (OR: 3.84, 95%, Increased BMI, may be more predictive of endometrial hyperplasia/malignancy than age in premenopausal women with abnormal uterine bleeding. Modification of evaluation guidelines in a contemporary demographic setting could be considered.
