RESUMO

Cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) is a common gynecologic tumor and patients with advanced and recurrent disease usually have a poor clinical outcome. Angiogenesis is involved in the biological processes of tumors and can promote tumor growth and invasion. In this paper, we created a signature for predicting prognosis based on angiogenesis-related lncRNAs (ARLs). This provides a prospective direction for enhancing the efficacy of immunotherapy in CESC patients. We screened seven OS-related ARLs by univariate and multivariate regression analyses and Lasso analysis and developed a prognostic signature at the same time. Then, we performed an internal validation in the TCGA-CESC cohort to increase the precision of the study. In addition, we performed a series of analyses based on ARLs, including immune cell infiltration, immune function, immune checkpoint, tumor mutation load, and drug sensitivity analysis. Our created signature based on ARLs can effectively predict the prognosis of CESC patients. To strengthen the prediction accuracy of the signature, we built a nomogram by combining signature and clinical features.

RESUMO

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors originating from perivascular epithelioid cells. In gynecological system, the uterus is one of the most common sites affected by PEComas. Most PEComas are benign, and patients usually have a good prognosis. However, malignant uterus PEComa is rare, and better comprehensive epidemiological investigations are needed. To date, there are a few reported cases of uterus PEComa. We herein report a rare case of malignant PEComa occurred in the uterine corpus and cervix, possibly accompanied by pulmonary lymphangioleiomyomatosis (PLAM). In addition, 55 cases of malignant uterus PEComa were picked out and collected in the data base of PubMed and Medline. On the one hand, the age of onset, population distribution, clinical manifestations, metastatic sites and routes of metastasis were analysed. On the other hand, a summary of the epidemiology, pathogenesis, diagnosis, and treatments of uterus PEComa was given.

RESUMO

Primary small bowel adenocarcinoma (SBA) is a rare gastrointestinal cancer with a low incidence of ovarian metastasis. Differential diagnosis of metastatic and primary ovarian cancer is often challenging. The present study reported the case of a 45-year-old woman with jejunal adenocarcinoma who presented with right ovarian, left ovarian, abdominopelvic implant and local recurrent bowel wall metastases successively after primary tumor resection. The ovarian masses of the patient originated from SBA, which was confirmed by immunohistochemical results. Following four comprehensive evaluations by an experienced multidisciplinary team (MDT) during the disease period, the patient underwent four operations, 28 cycles of chemotherapy, 24 cycles of targeted therapy and maintenance therapy for 8 months. As of February 2023, the patient has survived for 73 months and has a high quality of life. It is suggested that when a patient with SBA presents with an ovarian mass, the differential diagnosis between metastatic ovarian cancer and primary ovarian cancer mainly relies on immunohistochemistry. After a comprehensive evaluation by an experienced MDT, surgical resection is the primary treatment for advanced SBA, thus demonstrating some benefits for patients.

RESUMO

Background: Endometrial cancer (UCEC) is a highly heterogeneous gynecologic malignancy that exhibits variable prognostic outcomes and responses to immunotherapy. The Familial sequence similarity (FAM) gene family is known to contribute to the pathogenesis of various malignancies, but the extent of their involvement in UCEC has not been systematically studied. This investigation aimed to develop a robust risk profile based on FAM family genes (FFGs) to predict the prognosis and suitability for immunotherapy in UCEC patients. Methods: Using the TCGA-UCEC cohort from The Cancer Genome Atlas (TCGA) database, we obtained expression profiles of FFGs from 552 UCEC and 35 normal samples, and analyzed the expression patterns and prognostic relevance of 363 FAM family genes. The UCEC samples were randomly divided into training and test sets (1:1), and univariate Cox regression analysis and Lasso Cox regression analysis were conducted to identify the differentially expressed genes (FAM13C, FAM110B, and FAM72A) that were significantly associated with prognosis. A prognostic risk scoring system was constructed based on these three gene characteristics using multivariate Cox proportional risk regression. The clinical potential and immune status of FFGs were analyzed using CiberSort, SSGSEA, and tumor immune dysfunction and rejection (TIDE) algorithms. qRT-PCR and IHC for detecting the expression levels of 3-FFGs. Results: Three FFGs, namely, FAM13C, FAM110B, and FAM72A, were identified as strongly associated with the prognosis of UCEC and effective predictors of UCEC prognosis. Multivariate analysis demonstrated that the developed model was an independent predictor of UCEC, and that patients in the low-risk group had better overall survival than those in the high-risk group. The nomogram constructed from clinical characteristics and risk scores exhibited good prognostic power. Patients in the low-risk group exhibited a higher tumor mutational load (TMB) and were more likely to benefit from immunotherapy. Conclusion: This study successfully developed and validated novel biomarkers based on FFGs for predicting the prognosis and immune status of UCEC patients. The identified FFGs can accurately assess the prognosis of UCEC patients and facilitate the identification of specific subgroups of patients who may benefit from personalized treatment with immunotherapy and chemotherapy.

RESUMO

Endometriosis is a hormone-dependent inflammatory disease characterized by the existence of endometrial tissues outside the uterine cavity. Pharmacotherapy and surgery are the current dominant management options for endometriosis. The greater incidence of recurrence and reoperation after surgical treatment as well as the adverse effects of medical approaches predispose patients to potential limitations for their long-term usage. Consequently, it is essential to explore novel supplementary and alternative drugs to ameliorate the therapeutic outcomes of endometriotic patients. Resveratrol is a phenolic compound that has attracted increasing interest from many researchers due to its pleiotropic biological activities. Here, we review the possible therapeutic efficacies and molecular mechanisms of resveratrol against endometriosis based on in vitro, animal, and clinical studies. The potential mechanisms of resveratrol include anti-proliferative, pro-apoptotic, anti-angiogenic, anti-oxidative stress, anti-invasive and anti-adhesive effects, thereby suggesting that resveratrol is a promising candidate for endometriosis. Because most studies have investigated the effectiveness of resveratrol on endometriosis via in vitro trials and/or experimental animal models, further high-quality clinical trials should be undertaken to comprehensively estimate the clinical application feasibility of resveratrol on endometriosis.

RESUMO

Endometriosis is an estrogen-dependent inflammatory gynecological disorder that is pathologically defined as the growth of endometrial glands and stroma outside of the uterine cavity. It is estimated that more than 15% of women of reproductive age are affected by endometriosis. Immunological and inflammatory responses, anti-apoptotic effects and angiogenesis processes have been reported to be involved in endometriosis. Surgery and pharmacotherapy are applied in the treatment of this disease. Frustratingly, a high recurrence rate and/or side effects are observed during and after the treatments. In our previous study, we designed and synthesized serial analogs of naturally occurring flavokawain chalcones. Among these molecules, FK-morph exhibited excellent anti-inflammatory activity and showed therapeutic potential in vitro and in vivo. In the current study, we demonstrate the beneficial effects of FK-morph on a surgically induced endometriosis rat model. After treatment with FK-morph, the volumes and adhesion scores of implants in rats were effectively reduced and the levels of inflammatory cytokines and related chemokines in peritoneal fluid and blood were significantly downregulated. FK-morph also mediated cell apoptosis of endometriosis foci. In addition, the angiogenesis process was attenuated by decreasing the expression of VEGF. Meanwhile, the underlying mechanism was further explored. FK-morph effectively reduced the expression of Akt, p-Akt, PI3K, p-PI3K and NF-κB in endometriosis lesions. Overall, the results revealed the efficacy of FK-morph against endometriosis by reducing the levels of inflammatory factors, accelerating apoptosis and attenuating angiogenesis, which may be associated with blocking the activation of the PI3K/Akt and NF-κB signaling pathways.

RESUMO

Ovarian cancer is a malignant tumor of the female reproductive system, with a very poor prognosis and high mortality rates. Chemotherapy and radiotherapy are the most common treatments for ovarian cancer, with unsatisfactory results. Exosomes are a subpopulation of extracellular vesicles, which have a diameter of approximately 30-100 nm and are secreted by many different types of cells in various body fluids. Exosomes are highly stable and are effective carriers of immunotherapeutic drugs. Recent studies have shown that exosomes are involved in various cellular responses in the tumor microenvironment, influencing the development and therapeutic efficacy of ovarian cancer, and exhibiting dual roles in inhibiting and promoting tumor development. Exosomes also contain a variety of genes related to ovarian cancer immunotherapy that could be potential biomarkers for ovarian cancer diagnosis and prognosis. Undoubtedly, exosomes have great therapeutic potential in the field of ovarian cancer immunotherapy. However, translation of this idea to the clinic has not occurred. Therefore, it is important to understand how exosomes could be used in ovarian cancer immunotherapy to regulate tumor progression. In this review, we summarize the biomarkers of exosomes in different body fluids related to immunotherapy in ovarian cancer and the potential mechanisms by which exosomes influence immunotherapeutic response. We also discuss the prospects for clinical application of exosome-based immunotherapy in ovarian cancer.

RESUMO

Drug resistance is always a great obstacle in any endocrine therapy of breast cancer. Although the combination of endocrine therapy and targeted therapy has been shown to significantly improve prognosis, refractory endocrine resistance is still common. Dysregulation of the Hippo pathway is often related to the occurrence and the development of many tumors. Targeted therapies of this pathway have played important roles in the study of triple negative breast cancer (TNBC). Targeting the Hippo pathway in combination with chemotherapy or other targeted therapies has been shown to significantly improve specific antitumor effects and reduce cancer antidrug resistance. Further exploration has shown that the Hippo pathway is closely related to endocrine resistance, and it plays a "co-correlation point" role in numerous pathways involving endocrine resistance, including related pathways in breast cancer stem cells (BCSCs). Agents and miRNAs targeting the components of the Hippo pathway are expected to significantly enhance the sensitivity of breast cancer cells to endocrine therapy. This review initially explains the possible mechanism of the Hippo pathway in combating endocrine resistance, and it concludes by recommending endocrine therapy in combination with therapies targeting the Hippo pathway in the study of endocrine-resistant breast cancers.

RESUMO

This study aimed to develop a novel and practical fluorescent method for GSH detection in complex biological samples. To this end, a series of coumarin-based fluorescent probes was designed and synthesized using various aliphatic halogens as the sensing group. By using a new evaluation method of GSH/Cys/Hcy coexisting conditions, the probe with chloropropionate (CBF3) showed a high selectivity, excellent sensitivity, good stability for GSH detection. The reaction mechanism is proposed as nucleophilic substitution/cyclization and intramolecular charge transfer (ICT), which was confirmed by LC-MS and NMR analysis, as well as density functional theory calculations. In addition, CBF3 was demonstrated to be competent not only for the quantitative detection of GSH in real serum samples, but also for sensing GSH changes in different oxidative stress models in living cells and nematodes. This study showed a practical strategy for constructing GSH-specific fluorescent probes, and provided a sensitive tool for real-time sensing of GSH in real biological samples. The findings would greatly facilitate further investigations on GSH-associated clinical diagnosis and biomedical studies.

RESUMO

Inflammation is a complex biological response to stimuli. Activated macrophages induced excessively release of pro-inflammatory cytokines and mediators such as endogenous radical nitric oxide (NO) play a significant role in the progression of multiple inflammatory diseases. Both natural and synthetic chalcones possess a wide range of bioactivities. In this work, thirty-nine chalcones and three related compounds, including several novel ones, based on bioactive kava chalcones were designed, synthesized and their inhibitory effects on NO production in RAW 264.7 cells were evaluated. The novel compound (E)-1-(2'-hydroxy-4',6'-dimethoxyphenyl)-3-(3-methoxy-4-(3-morpholinopropoxy)phenyl)prop-2-en-1-one (53) exhibited a better inhibitory activity (84.0%) on NO production at 10 µM (IC50 = 6.4 µM) with the lowest cytotoxicity (IC50 > 80 µM) among the tested compounds. Besides, western blot analysis indicated that compound 53 was a potent down-regulator of inducible nitric oxide synthase (iNOS) protein. Docking study revealed that compound 53 also can dock into the active site of iNOS. Furthermore, at the dose of 10 mg/kg/day, compound 53 could both significantly suppress the progression of inflammation on collagen-induced arthritis (CIA) and adjuvant-induced arthritis (AIA) models. In addition, the structure-activity relationship (SAR) of the kava chalcones based analogs was also depicted.

RESUMO

The clinical use of the steroidal aromatase inhibitor Formestane (4-hydroxandrostenedione, 4-OHA) in the treatment of advanced ER+ breast cancer has been discontinued, and therefore, interest in this remarkable drug has vanished. As a C-19 sterol, 4-OHA can undergo extensive intracellular metabolism depending on the expression of specific enzymes in the corresponding cells. We used the metabolites 4ß-hydroxyandrosterone, 4ß-hydroxyepiandrosterone and its 17ß-reduced derivative as standards for the proof of catalytic activity present in the cell culture medium and expressed by the isolated enzymes. All of the aldo-keto reductases AKR1C1, AKR1C2, AKR1C3 and AKR1C4 catalysed the reduction of the 3-keto-group and the Δ4,5 double bond of 4-OHA at the same time. Molecular docking experiments using microscale thermophoresis and the examination of the kinetic behaviour of the isolated enzymes with the substrate 4-OHA proved that AKR1C3 had the highest affinity for the substrate, whereas AKR1C1 was the most efficient enzyme. Both enzymes (AKR1C1and AKR1C3) are highly expressed in adipose tissue and lungs, exhibiting 3ß-HSD activity. The possibility that 4-OHA generates biologically active derivatives such as the androgen 4-hydroxytestosterone or some 17ß-hydroxy derivatives of the 5α-reduced metabolites may reawaken interest in Formestane, provided that a suitable method of administration can be developed, avoiding oral or intramuscular depot-injection administration.

RESUMO

OBJECTIVE: Preterm labor is one of the most significant obstetric problems associated with high rate of actual and long-term perinatal complications. Despite the creation of scoring systems, uterine activity monitoring, cervical ultrasound and several biochemical markers, the prediction and prevention of preterm labor is still a matter of concern. The aim of this study was to examine cervical findings for the prediction and the comparative use of Arabin pessary or cerclage for the prevention of preterm birth in asymptomatic women with high risk factors for preterm labor. MATERIAL AND METHODS: The study group was composed of singleton pregnancies (spontaneously conceived) with high risk factors for preterm labor. Cervical length, dilatation of the internal cervical os and funneling, were estimated with transvaginal ultrasound during the first and the second trimesters of pregnancy. RESULTS: Cervical funneling, during the second trimester of pregnancy, was the most significant factor for the prediction of preterm labor. The use of Arabin cervical pessary was found to be more effective than cerclage in the prolongation of pregnancy. CONCLUSION: In women at risk for preterm labor, the detection of cervical funneling in the second trimester of pregnancy may help to predict preterm labor and to apply the appropriate treatment for its prevention. Although the use of cervical pessary was found to be more effective than cerclage, more studies are needed to classify the effectiveness of different methods for such prevention.

RESUMO

OBJECTIVE: The objective of this study is to assess retrospectively the predictive value of fetal scalp pH and base excess (BE) for fetal acidosis and poor neonatal outcome in term, low-risk, spontaneous deliveries with suspicious or pathological intrapartum cardiotocography (CTG) tracings. METHODS: Umbilical artery pH and BE values obtained immediately after delivery and Apgar score were the outcomes under consideration. Statistics included receiver-operating characteristic curve (ROC) and multiple logistic regression analysis. RESULTS: Four hundred and six deliveries were included in the study. Scalp pH < 7.20 predicted umbilical pH ≤7.1 with 64.3% sensitivity and 92.9% specificity (p < .001). The corresponding positive-predictive value (PPV) was 24.3% and the negative-predictive value (NPV) was 98.6%. Scalp BE ≤ -7 mmol/l (a cut-off value provided by ROC curve analysis) predicted Apgar score ≤ 7 at 5 min with 61.9% sensitivity and 91.7% specificity (p < .001). The corresponding PPV and NPV were 29.5 and 97.7%, respectively. Neither scalp pH nor BE was significantly associated with umbilical BE values. Infants with intrapartum BE ≤ -7 mmol/l were 30 times on an average more likely to get a low Apgar score, independently of intrapartum pH values. CONCLUSION: Our study supports the consideration of both scalp pH and BE values, when fetal blood sampling (FBS) is used.

RESUMO

The approval of the first specific drug catumaxomab for the treatment of malignant ascites is the subject of this review. This trifunctional antibody is known to kill EpCAM-positive tumor cells and therefore attacks the primary cause of malignant ascites formation in the peritoneal cavity. Until today catumaxomab is the only EpCam-targeted antibody approved by the European Medicines Agency. Ovarian cancer is caused by epithelial tumors cells which overexpress epithelial cell adhesion molecule (EpCAM). The existing literature concerning the use of catumaxomab for the treatment of malignant ascites associated with ovarian cancer until today is reported in this article. It is very encouraging that different prospective studies from diverse scientific teams recently presented positive results concerning the efficacy and the safety of catumaxomab in the treatment of malignant ascites in patients with ovarian cancer. A case of a patient with ovarian cancer FIGO IIIc is also referred in this article. A complete remission and stable disease was found after 4 i.p. infusions of catumaxomab.

RESUMO

AIM: The aim of this study was to evaluate the outcome of pregnancies in adolescents in the Department of Obstetrics and Gynaecology of Democritus University of Thrace, North-Eastern Greece. MATERIAL AND METHODS: We retrospectively reviewed 194 cases of adolescent pregnancies, with an average maternal age of 16.5 years, from 1st January 2006 to December 30th 2008. Socioeconomic characteristics, type of delivery and complications, such as preterm labor, preeclampsia, intra- and post-partum complications, were evaluated. RESULTS: The median age at first intercourse was 14.2 years and the average period between first intercourse and pregnancy was 1.2 years. Most teen mothers (86.6%) did not use any contraceptive method. Among the teen mothers recruited for the study, 89.7% were married. Adolescent pregnancies accounted for 9.02% of all deliveries (2150) in our Department. In 49 (25.3%) of the pregnant adolescents, no previous pregnancy was reported. The rates of preterm birth of teen mothers were 11.3%, 41.3% and 47.4% in correlation to <32 weeks, 32-34 weeks and >34 weeks, respectively. In 95.4% of the cases, deliveries were not complicated. According to our results, the main complications, especially in very young girls, are preterm labor, anaemia, hypertensive disease, obstructed labor after premature rupture of the membranes and increased neonatal mortality and morbidity. Antenatal care is often inadequate. CONCLUSION: Early teenage pregnancies have always been considered of increased risk for obstetric complications. Prevention of adolescent pregnancy, by wide use of effective contraception programs, would decrease its frequency and intensive care of pregnant adolescents may reduce the pregnancy complications.

RESUMO

OBJECTIVE: The aim of this comparative study was to ascertain the efficacy of the Sulmycin® Implant E, an antiseptic sponge, on the incidence of peri- and postoperative morbidity in patients subjected to vaginal hysterectomy. MATERIAL AND METHODS: This eleven-year study included 228 patients undergoing vaginal hysterectomy. The patients were divided into two groups. Group A included 169 participants with benign diseases (fibroids, dysfunctional uterine bleeding and prolapse) and group B included 59 patients with early stage endometrial cancer or atypical hyperplasia. Women of both groups were further divided into three subgroups: (a) receiving a single dose of intravenous cefuroxime (2 gr) (group A: 55, group B: 19), (b) receiving three doses of intravenous cefuroxime (2 gr) (group A: 54, group B: 19), and (c) locally placed a collagen sponge containing gentamycin (Sulmycin® Implant E) (group A: 60, group B: 21). RESULTS: The number of postoperative infections (mainly urinary tract infections) did not differ between women of the three subgroups of patients in both groups. There were no important differences affecting the postoperative hospitalization, healing procedure and adhesion of the cuff between women of the three subgroups in both groups. CONCLUSION: The local chemoprophylaxis with Sulmycin® Implant E, a collagen sponge containing gentamycin and placed on the vaginal cuff, is well tolerated and equally effective as intravenous antibiotics.

RESUMO

AIM: The aim of this study was to investigate the impact of radical lymphadenectomy as a prognostic factor in the management of uterine sarcomas. METHODS: Sixty patients with histologically-proven uterine sarcomas were recruited for this study. The patients were evaluated retrospectively, during the time period from September 1990 to June 2008, in the Department of Obstetrics and Gynecology of Aschaffenburg Clinic in Germany. The normality of the quantitative variables was tested using the Kolmogorov-Smirnov test. RESULTS: Of 60 patients, 35 (58.3%) underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and pelvic or para-aortic lymphadenectomy. The excision of iliac nodes was the strongest and most independent factor (ß = 0.64, P = 0.000) associated with survival. Recurrence of disease developed in 14 out of 25 patients (56%) who did not receive lymphadenectomy, but in only 10 out of 35 patients (29%) who underwent lymphadenectomy. The mean survival in years after surgery plus lymphadenectomy was 5.28 years, while in patients who did not undergo lymphadenectomy it was 1.56 years. CONCLUSIONS: Removal of lymphatic tissue in patients with early-stage uterine sarcoma significantly decreases the recurrence rate of the disease and improves the postoperative survival. However, there is a need for further prospective randomized controlled trials to investigate the adequate surgical management of uterine sarcomas and to clarify the prognostic value of lymphadenectomy at the initial surgery.

RESUMO

BACKGROUND: Endometrial carcinoma is the most distressing cause of abnormal vaginal bleeding. The intention of clinical management in the case of postmenopausal bleeding is to achieve an accurate diagnosis without overinvestigation. METHOD: We studied the available literature on the diagnostic evaluation of postmenopausal women with vaginal bleeding, accentuating the most important aspects on this topic: the accuracy of sonography and endometrial biopsy in predicting endometrial hyperplasia and endometrial carcinoma. RESULTS: The accuracy of the above tests in predicting endometrial hyperplasia and endometrial carcinoma is a subject of continuing debate. Μοreover, in the last decades, there has been an explosion of publications indicating that ultrasound may be useful in predicting endometrial pathology. CONCLUSION: Since advanced endometrial carcinoma has been known to occur in cases without noticeable endometrial thickness on ultrasound, the clinician should beware of the diagnostic evaluation of postmenopausal women with vaginal bleeding.

Uterine sarcomas are rare and aggressive gynaecologic malignancies with poor prognosis, arising from myometrial or endometrial tissue. These rare cancers can be aggressive, and account for a greatly disproportionate amount of deaths from uterine cancers. The histological uterine sarcomas classification includes carcinosarcomas (malignant mesodermal mixed tumors), accounting for 40% of cases, leiomyosarcomas (40%) and endometrial stromal sarcomas (10-15%). Each group of these tumors presents differences in diagnosis, prognostic factors, treatment, and outcome. Uterine leiomyosarcomas typically affects women in their sixth decade of life, presenting with atypical symptoms such as abnormal uterine bleeding and abdominal pain. The optimal treatment of uterine leiomyosarcomas is surgery, including total abdominal hysterectomy and bilateral salpingooophorectomy. The aim of this study was to conduct a systematic review of the literature regarding the standard surgical procedure of uterine leiomyosarcomas and investigate whether lymphadenectomy affects the 5-year DSS, as well as other relevant clinical outcomes, in women with uterine leiomyosarcomas. For this purpose, MEDLINE, EMBASE, and the Cochrane Library databases were reviewed, and a critical account of the management strategies of these tumors is presented.
