Gynecological cancers comprise about 19% of all cancers in women whereas the endometrial cancer is the most common malignant tumor of the female reproductive organs. The application of modern imaging tools plays an important role in the preoperative assessment of disease extent and allows the selection of a proper and adequate therapeutic approach for each patient. The purpose of this review was to show the role of magnetic resonance imaging (MRI) in the evaluation of endometrial carcinoma. MRI enables the display of zonal anatomy of the uterus, detection of the anomalies as well as the detection and characterization of pathological processess...

Neoplasms of the ovary are the second most common tumor of the female reproductive system, and the most lethal of the gynecological malignancies. Ovarian tumors are divided into a copious number of different groups reflecting their different features. The present study analyzed 187 ovarian tumors (39 sex-cord stromal tumors, 22 borderline tumors and 126 carcinomas) for the expression of the high-mobility group AT-hook 2 (HMGA2) gene, for mutations in the isocitrate dehydrogenase (NADP(+)) 1, cytosolic (IDH1), isocitrate dehydrogenase (NADP(+)) 2, mitochondrial (IDH2) and telomerase reverse transcriptase (TERT) genes, and for methylation of the O(6)-methylguanine-DNA methyltransferase (MGMT) promoter...

Growth factor receptor-bound protein-2 (Grb2) can act as the scaffold protein recruiting other molecules to the stimulated receptors. Grb2-associated binding protein 1 (Gab1) is involved in cell proliferation, and its expression may enhance the carcinogenesis and cancer progression. However, the function of Gab1 remains to be investigated. Epithelial ovarian cancer (EOC) is the most lethal malignancy in the female reproductive system with increasing incidence and unsatisfied overall survival (OS). We investigated the expression of Gab1 in EOC tissues and the correlations between Gab1 expression and the clinicopathological characteristics of patients with EOC using Spearman rank test...

PURPOSE: Ovarian cancer is the most lethal malignancy of the female reproductive system, and the prevention and treatment of ovarian carcinoma are still far from optimal. Epidemiological studies reported that ovarian cancer risk was inversely associated with low level of 25-hydroxy vitamin D [25(OH)]. Therefore, this study focuses on exploring the chemoprevention of vitamin D on epithelial ovarian cancer induced by 7, 12-dimethylbenz [a] anthracene (DMBA). METHODS: The mouse ovarian surface epithelial cells were isolated from estrus mice by mild trypsinization and maintained in completed culture medium by repeated passaging...

BACKGROUND: Human reproduction depends on an intact hypothalamic-pituitary-gonadal (HPG) axis. Hypothalamic gonadotrophin-releasing hormone (GnRH) has been recognized, since its identification in 1971, as the central regulator of the production and release of the pituitary gonadotrophins that, in turn, regulate the gonadal functions and the production of sex steroids. The characteristic peculiar development, distribution and episodic activity of GnRH-producing neurons have solicited an interdisciplinary interest on the etiopathogenesis of several reproductive diseases...

As one of the most common malignant cancers in female reproductive tract, endometrial cancer accounts for 20-30 % of the most frequent gynecological malignancy, which is originated from endometrial epithelial. The molecular mechanisms for the generation of endometrial cancer are up to now unclear, hindering the development of corresponding therapy. CXCR4 and CXCR7 were receptors of CXCL12 chemokine ligand, which could regulate critical procedures of neoplastic transformation, including proliferation, invasion, and apoptosis of the cells...

Defects of the perineum may result from ablative procedures of different malignancies. The evolution of more radical excisional surgery techniques resulted in an increase in large defects of the perineum. The perineogenital region per se has many different functions for urination, bowel evacuation, sexuality, and reproduction. Up-to-date individual and interdisciplinary surgical treatment concepts are necessary to provide optimum oncological as well as quality of life outcome. Not only the reconstructive method but also the timing of the reconstruction is crucial...

Ovarian cancer remains the dominant cause of death due to malignancies of the female reproductive system. The capability to identify and remove all tumors during intraoperative procedures may ultimately reduce cancer recurrence, and lead to increased patient survival. The objective of this study is to investigate the effectiveness of an optical nano-structured system for targeted near infrared (NIR) imaging of ovarian cancer cells that over-express the human epidermal growth factor receptor 2 (HER2), an important biomarker associated with ovarian cancer...

Ovarian cancer represents the most lethal tumor type among malignancies of the female reproductive system. Overall survival rates remain low. In this study, we identify the serine protease inhibitor Kazal type 1 (SPINK1) as a potential therapeutic target for a subset of ovarian cancers. We show that SPINK1 drives ovarian cancer cell proliferation through activation of epidermal growth factor receptor (EGFR) signaling, and that SPINK1 promotes resistance to anoikis through a distinct mechanism involving protease inhibition...

Cervical cancer is the most common cancer of the female reproductive system up to 20% of malignant tumors of the female genital organs. Surgery is the main method in treatment for local cervical cancer but postoperative complications often are associated with dysfunction of the pelvic organs. Some researchers focus their attention on the preservation of the pelvic innervation without loss of surgery's radicalism, which is represented in this survey. The paper presents the results of comparative analysis of 54 cases of surgical treatment for invasive cervical cancer...

Primary malignant lymphomas affecting the female reproductive system are unusual, accounting for about 30% of all lymphomas. The majority of them are represented by non-Hodgkin lymphomas (over 90%), as their location most commonly involved the ovarian (49%), followed by the uterus (29%), fallopian tubes (11%), vagina (7%), and only in 4% of the cases, the primary lymphomas affecting the vulva. Although rare, lymphomas of the vulva are characterized by high proliferative potential, aggressive clinical course and poor prognosis and may lead to rapid vulvar and perineal destruction...

Due to the increased vascularity as well as the unique anatomical structure, vascular lesions, which occur in the female reproductive system are common observed and diverse by their morphology. The majority of them are benign, including vascular malformations, lesions due to vascular hyperplasia, tumors with significant vascular component and others. Malignant vascular tumors are rare in the area of the vulva accounting about 1% of all vulvar lesions with vascular origin. Kaposi sarcoma, epithelioid hemangioepithelioma and epithelioid angiosarcoma have been reported with vulvar localization...
