Krukenberg tumors are very rare. Its origin is difficult to define especially if its gross features mimic a primary ovarian cancer. We present a case of a 24-year-old Filipino female patient with metastatic mucinous ovarian adenocarcinoma of colonic origin that mimicked primary ovarian cancer and genitourinary tuberculosis. Surgery was done and histopathology revealed that the cancer was a metastatic mucinous adenocarcinoma of colonic origin. This case highlights the importance of differentiating between benign and malignant ovarian lesions as well as distinction between primary and metastatic ovarian neoplasms. Radiological imaging has an evolving role in diagnosis of different cancers, which may be improved through better clinical correlation and developing meaningful differential diagnosis while advancing to a more strategized algorithm in the diagnostic approach.

Objective: To evaluate the incidence, treatment, and survival outcomes of Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumor (MGCT-NDG). Methods: A retrospective study was performed on Swyer syndrome patients with MGCT-NDG between January 2011 and December 2022 in Peking Union Medical College Hospital to investigate their characteristics and outcomes. Results: A total of 15 patients (4.9%, 15/307) with Swyer syndrome were identified in 307 MGCT-NDG patients. The average age at diagnosis of MGCT-NDG and Swyer syndrome were (16.8±6.7) and (16.7±6.6) years, respectively. Six cases were preoperatively diagnosed as Swyer syndrome, of which 4 cases received bilateral gonadectomy with or without hysterectomy, while the other 2 cases underwent removal of gonadal tumor and unilateral gonadectomy with hysterectomy, respectively. Of the 9 patients postoperatively diagnosed as Swyer syndrome, unilateral gonadectomy, removal of gonadal tumor, and unilateral gonadectomy with hysterectomy were performed in 6 patients, 2 patients, and 1 patient, respectively. Mixed malignant germ cell tumor (MGCT;10 cases), yolk sac tumor (4 cases), and immature teratoma (1 case) were the pathological subtypes, in the descending order. There were International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ in 6 cases, stage Ⅱ in 3 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case, respectively. Eleven patients received reoperation for residual gonadectomy after a average delay of (7.9±6.2) months, including 8 MGCT-NDG patients and 1 gonadoblastoma patient, no tumor involved was seen in the remaining gonads in the other 2 cases. Ten patients experienced at least one recurrence, with a median event free survival of 9 months (5, 30 months), of which 2 patients received surgery only at the time of initial treatment. All patients with recurrence received surgery and combined with postoperative chemotherapy. After a median follow-up of 25 months (15, 42 months), 10 patients were disease-free, 3 patients died of the tumor, 1 died of side effects of leukemia chemotherapy, and 1 survived with disease. Conclusion: The incidence rate of Swyer syndrome in patients with MGCT-NDG is about 4.9%; timely diagnosis and bilateral gonadectomy should be emphasized to reduce the risk of reoperation and second carcinogenesis in this population.

Small-cell carcinoma of the ovary, hypercalcemic type (SCCOHT), is a rare and aggressive type of ovarian cancer. It generally presents in younger patients, is diagnosed at an advanced stage, and is associated with a dismal prognosis. Due to its rarity and morphologic similarity to more common ovarian tumors, diagnosis may be a challenge. A high index of suspicion followed by appropriate immunohistochemistry stains performed by an expert pathologist is essential to diagnosis. Two cases of SCCOHT are presented: 21 years old with rapidly progressive Stage IIIA1i disease who underwent surgery and succumbed to the illness after 3 months before adjuvant treatment could be given, and a 49 years old with Stage IIIB disease with tumor progression who is on adjuvant chemotherapy and apparently well, 21 months after her first symptoms appeared. Related literature is presented and compared to the features of the index cases. Diagnosis and treatment options are also discussed briefly.

OBJECTIVE

To determine the threshold value for anti-Müllerian hormone (AMH) in the diagnosis of polycystic ovarian syndrome (PCOS) in infertile Filipino women and to ascertain the correlation of AMH with age and body mass index of PCOS women.

A retrospective cross-sectional study was carried out on infertile Filipino women at the Center for Advanced Reproductive Medicine and Infertility from August 2015 to March 2020. The women were separated into the PCOS group and male factor infertility group. Serum AMH was analyzed with Access AMH chemiluminescent immunoassay by Beckman Coulter. The AMH threshold for the diagnosis of PCOS was computed using Youden’s index.

There were 585 women included in the study, 311 (53.16%) were diagnosed with PCOS by the Rotterdam criteria, while 274 (46.84%) were non PCOS women. Mean serum AMH for PCOS was 5.88 ± 3.37 (p < 0.01). A threshold value of serum AMH above 3.86 ng/ml was predictive of PCOS by Youden’s index with a sensitivity of 67.2%, specificity of 77.7%, and correct classification rate of 72.1%. There was a negative correlation of AMH level with increasing age in both PCOS and non – PCOS group but the PCOS group had a higher AMH level. There was no correlation noted with AMH and body mass index in both groups.

AMH levels were higher in the PCOS women compared to those without the diagnosis. AMH threshold level could support the diagnosis of PCOS in infertile Filipino women.

Background: Ovarian, fallopian tube, and peritoneal cancer patients with advanced-stage diagnosis or recurrences spread to the peritoneal surface of the abdomen. Hyperthermic intraperitoneal chemotherapy (HIPEC) can penetrate and eradicate tumors that are microscopic up to those with a diameter of 2.5 cm from the peritoneal surface following cytoreductive surgery (CRS). Objectives: The study aimed to determine the efficacy and safety of CRS with HIPEC versus CRS alone for patients with epithelial ovarian, fallopian tube, and peritoneal cancer. Materials and Methods: This retrospective cohort study included 50 patients (20 patients underwent CRS + HIPEC, while 30 patients underwent CRS alone). Records of these patients from January 2014 to June 2020 were reviewed, tabulated, and analyzed. Results: The difference in recurrence rate between CRS with HIPEC and CRS alone was not statistically significant (50% vs. 43%, P = 0.774). The median time to recurrence was 10 and 9 months, respectively (P = 0.636). Five percent in the HIPEC group succumbed to the disease, while 13% died in the CRS alone group (P = 0.636). More post-operative complications were noted in the HIPEC group (45% vs. 10%, P = 0.007), but among these, only 2 cases had grade 3 to 4 complications (10%). The addition of HIPEC in the management of these patients resulted in a longer operative time (360 vs. 240 min, P < 0.001) and postoperative hospital stay (8 vs. 6 days, P = 0.026). There were no intra- or peri-operative mortalities in both groups. Conclusion CRS with HIPEC and CRS alone showed similar time to recurrence and recurrence rate. CRS with HIPEC had low risk of grade 3-4 complications and may still be considered as a treatment option for advanced, progressive, and recurrent epithelial ovarian, fallopian tube, and peritoneal cancer.

Poly ADP-ribose polymerase inhibitors (PARPi), which approved in recent years, are recommended for ovarian cancer, breast cancer, pancreatic cancer, prostate cancer and other cancers by The National Comprehensive Cancer Network (NCCN) and Chinese Society of Clinical Oncology (CSCO) guidelines. Because most of PARPi are metabolized by cytochrome P450 enzyme system, there are extensive interactions with other drugs commonly used in cancer patients. By setting up a consensus working group including pharmaceutical experts, clinical experts and methodology experts, this paper forms a consensus according to the following steps: determine clinical problems, data retrieval and evaluation, Delphi method to form recommendations, finally formation expert opinion on PARPi interaction management. This paper will provide practical reference for clinical medical staff.

OBJECTIVE: To explore the possible mechanism of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on premature ovarian insufficiency (POI) from the perspective of oxidative stress. METHODS: Sixty female SD rats were randomly divided into a blank group, a model group, a sham acupuncture group, a medication group, and an acupuncture group, 12 rats in each group. Except the blank group, the rats in the remaining groups were intraperitoneally injected with cyclophosphamide to establish the POI model. After the model was successfully established, the rats in the acupuncture group were treated with acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28), with a depth of about 12 mm, and the needle was retained for 30 min; the acupuncture was given once a day, for a total of 4 weeks. The rats in the sham acupuncture group were treated with blunt-head needle to tap the skin surface of "Zhibian" (BL 54), without penetrating the skin, once a day for 4 weeks. The rats in the medication group were treated with estradiol valerate by gastric gavage for 4 weeks. After the intervention, the level of reactive oxygen species (ROS) in the ovarian tissue was detected by fluorescence probe; the expression of c-Jun N-terminal kinase (JNK), forkhead box O1 (FoxO1), tumor suppressor gene protein 53 (p53) and p53 up-regulated modulator of apoptosis (Puma) mRNA and protein in ovarian tissue were detected by real-time fluorescence quantitative PCR and Western blot. RESULTS: Compared with the blank group, the level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the model group were increased (P<0.01). Compared with the model group, the level of ROS and the expression of p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the sham acupuncture group were slightly reduced, but the difference was not statistically significant (P>0.05). The level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the acupuncture group and the medication group were reduced (P<0.01). CONCLUSION Acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) could improve the level of oxidative stress, down-regulate the expression of apoptosis-related factors JNK, FoxO1, p53 and Puma induced by oxidative stress, and inhibit the premature failure of ovarian reserve function caused by apoptosis of ovarian granulosa cells in POI rats.

BACKGROUND: Ovarian cancer is one of the most widespread malignant diseases of the female reproductive system worldwide. The plurality of ovarian cancer is diagnosed with metastasis in the abdominal cavity. Epithelial-mesenchymal transition (EMT) exerts a vital role in tumor cell metastasis. However, it remains unclear whether long non-coding RNA (lncRNA) are implicated in EMT and influence ovarian cancer cell invasion and metastasis. This study was designed to investigate the impacts of lncRNA AC005224.4 on ovarian cancer. METHODS: LncRNA AC005224.4, miR-140-3p, and snail family transcriptional repressor 2 ( SNAI2 ) expression levels in ovarian cancer and normal ovarian tissues were determined using real-time quantitative polymerase chain reaction (qRT-PCR). Cell Counting Kit-8 (CCK-8) and Transwell (migration and invasion) assays were conducted to measure SKOV3 and CAOV-3 cell proliferation and metastasis. E-cadherin, N-cadherin, Snail, and Vimentin contents were detected using Western blot. Nude mouse xenograft assay was utilized to validate AC005224.4 effects in vivo . Dual-luciferase reporter gene assay confirmed the targeted relationship between miR-140-3p and AC005224.4 or SNAI2 . RESULTS: AC005224.4 and SNAI2 upregulation and miR-140-3p downregulation were observed in ovarian cancer tissues and cells. Silencing of AC005224.4 observably moderated SKOV3 and CAOV-3 cell proliferation, migration, invasion, and EMT process in vitro and impaired the tumorigenesis in vivo . miR-140-3p was a target of AC005224.4 and its reduced expression level was mediated by AC005224.4. miR-140-3p mimics decreased the proliferation, migration, and invasion of ovarian cancer cells. SNAI2 was identified as a novel target of miR-140-3p and its expression level was promoted by either AC005224.4 overexpression or miR-140-3p knockdown. Overexpression of SNAI2 also facilitated ovarian cancer cell viability and metastasis. CONCLUSION AC005224.4 was confirmed as an oncogene via sponging miR-140-3p and promoted SNAI2 expression, contributing to better understanding of ovarian cancer pathogenesis and shedding light on exploiting the novel lncRNA-directed therapy against ovarian cancer.

The present study aimed to explore the main active components and underlying mechanisms of Marsdenia tenacissima in the treatment of ovarian cancer(OC) through network pharmacology, molecular docking, and in vitro cell experiments. The active components of M. tenacissima were obtained from the literature search, and their potential targets were obtained from SwissTargetPrediction. The OC-related targets were retrieved from Therapeutic Target Database(TTD), Online Mendelian Inheritance in Man(OMIM), GeneCards, and PharmGKB. The common targets of the drug and the disease were screened out by Venn diagram. Cytoscape was used to construct an "active component-target-disease" network, and the core components were screened out according to the node degree. The protein-protein interaction(PPI) network of the common targets was constructed by STRING and Cytoscape, and the core targets were screened out according to the node degree. GO and KEGG enrichment analyses of potential therapeutic targets were carried out with DAVID database. Molecular docking was used to determine the binding activity of some active components to key targets by AutoDock. Finally, the anti-OC activity of M. tenacissima extract was verified based on SKOV3 cells in vitro. The PI3K/AKT signaling pathway was selected for in vitro experimental verification according to the results of GO function and KEGG pathway analyses. Network pharmacology results showed that 39 active components, such as kaempferol, 11α-O-benzoyl-12β-O-acetyltenacigenin B, and drevogenin Q, were screened out, involving 25 core targets such as AKT1, VEGFA, and EGFR, and the PI3K-AKT signaling pathway was the main pathway of target protein enrichment. The results of molecular docking also showed that the top ten core components showed good binding affinity to the top ten core targets. The results of in vitro experiments showed that M. tenacissima extract could significantly inhibit the proliferation of OC cells, induce apoptosis of OC cells through the mitochondrial pathway, and down-regulate the expression of proteins related to the PI3K/AKT signaling pathway. This study shows that M. tenacissima has the characteristics of multi-component, multi-target, and multi-pathway synergistic effect in the treatment of OC, which provides a theoretical basis for in-depth research on the material basis, mechanism, and clinical application.

Healthy birth and child development are the prerequisite for improving the overall quality of the population. However, premature ovarian failure(POF) threatens the reproductive health of women. The incidence of this disease has been on the rise, and it tends to occur in the young. The causes are complex, involving genetics, autoimmune, infectious and iatrogenic factors, but most of the causes remain unclear. At the moment, hormone replacement therapy and assisted reproductive technology are the main clinical approaches. According to traditional Chinese medicine(TCM), kidney deficiency and blood stasis are one of the major causes of POF, and TCM with the effects of tonifying kidney and activating blood has a definite effect. Through clinical trials, TCM prescriptions for POF have excellent therapeutic effect as a result of multi-target regulation and slight toxicity. In particular, they have no obvious side effects. A large number of studies have shown that the kidney-tonifying and blood-activating TCM can regulate the neuroendocrine function of hypothalamic-pituitary-ovarian axis, improve ovarian hemodynamics and microcirculation, reduce the apoptosis of granulosa cells, alleviate oxidative stress injury, and modulate immunologic balance. The mechanism is that it regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), vascular endothelial growth factor(VEGF), transforming growth factor(TGF)-β/Smads, nuclear factor E2-related factor 2(Nrf2)/antioxidant response element(ARE), and nuclear factor-kappa B(NF-κB) signaling pathways. This article summarized the pathological mechanisms of tonifying kidney and activating blood TCM in the prevention and treatment of POF and explored the biological basis of its multi-pathway and multi-target characteristics in the treatment of this disease. As a result, this study is expected to serve as a reference for the treatment of POF with the tonifying kidney and activating blood therapy.
