PURPOSE: Apparent diffusion coefficient (ADC) histogram analysis has been used to some extent in cervical cancer (CC) to distinguish between low-grade and high-grade tumors. Although this differentiation is undoubtedly helpful, it would be even more crucial in the presurgical setting to determine whether a tumor already gained the potential to metastasize via the lymphatic system. So far, no studies investigated the potential of 3T ADC histogram analysis in CC to differentiate between nodal-positive and nodal-negative entities...

Importance: Cancer occurs in 0.05% to 0.1% of all pregnancies. Despite literature reporting good oncologic and fetal outcomes in women treated for cancer during pregnancy, as many as 44% of gynecologists would offer termination, and 37% would not administer chemotherapy or radiotherapy in pregnancy. Objectives: The aims of this study were to summarize current recommendations for the treatment of cervical and ovarian cancers in pregnancy and to review updates on existing knowledge regarding the safety of surgical and chemotherapeutic treatments in pregnancy, including both oncologic and fetal outcomes...

Cervical cancer is an infectious cancer and the most common gynecologic cancer worldwide. E6/E7, the early genes of the high-risk mucosal human papillomavirus type, play key roles in the carcinogenic process of cervical cancer. However, little was known about its roles in modulating tumor microenvironment, particular extracellular matrix (ECM). In this study, we found that E6/E7 could regulate multiple ECM proteins, especially collagen triple helix repeat containing 1 (CTHRC1). CTHRC1 is highly expressed in cervical cancer tissue and serum and closely correlated with clinicopathological parameters...

The Japanese Gynecologic Oncology Group (JGOG) is leading Japan in the treatment of gynecological malignancies. The JGOG consists of three treatment committees focusing on uterine cervical cancer, endometrial cancer, and ovarian cancer. Each committee makes efforts to improve treatment and diagnosis. In addition, the Supportive and Palliative Care Committee was established in 2015. Novel studies of supportive care and palliative care have been initiated by this committee. Furthermore, surveys about not only treatment results such as overall survival rates but also quality of life (QOL) and cost-effectiveness assessments are performed by the ovarian cancer committee...

PURPOSE: Treatment for gynecologic cancers, such as cervical, recurrent endometrial, and vaginal malignancies, commonly includes external-beam radiation and brachytherapy. In high-dose-rate (HDR) interstitial gynecologic brachytherapy, radiation treatment is delivered via hollow needles that are typically inserted through a template on the perineum with a cylinder placed in the vagina for stability. Despite the need for precise needle placement to minimize complications and provide optimal treatment, there is no standard intra-operative image-guidance for this procedure...

As the advantage of using complex volumetric-modulated arc therapy (VMAT) in the treatment of gynecologic cancer has not yet been fully determined, the purpose of this study was to investigate the dosimetric advantages of VMAT by comparing directly with whole pelvic conformal radiotherapy (CRT) and intensity-modulated radiotherapy (IMRT) in the treatment of 15 postoperative cervical cancer patients. Four-field CRT, seven-field IMRT, and two-arc VMAT plans were generated for each patient with identical objective functions to achieve clinically acceptable dose distribution...

The treatment of advanced gynecologic cancers remains palliative in most of cases. Although systemic treatment has entered into the era of targeted drugs the antitumor efficacies of current therapies are still limited. In this context there is a great need for more active treatment and rationally designed targeted therapies. The PI3K/AKT/mTOR is a signaling pathway in mammal cells that coordinates important cell activities. It has a critical function in the survival, growth, and proliferation of malignant cells and was object of important research in the last two decades...

BACKGROUND: Previous studies revealed low participation in cervical cancer screening among immigrants compared with non-immigrants. Only a few studies about factors associated with immigrants' lower participation rates have been conducted in European countries that have universal access for all eligible women. Our study aimed to explore factors associated with cervical screening participation among women of Russian, Somali, and Kurdish origin in Finland. METHODS: We used data from the Migrant Health and Well-being Survey, 2010-2012...

Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix...

Vulvar cancers, which constitute 5% of all gynecologic cancers, are the fourth most common female genital cancers, preceded by uterine, ovarian and cervical cancers. The treatment methods employed for vulvar cancers have changed over the years, with previously applied radical surgical approaches, such as en bloc resection, being gradually suspended in favor of treatment approaches that require dissection of less tissue. While the removal of less tissue, which today's approaches have focused on, prevents morbidity, this method seems to result in higher risks of recurrence...

Clear cell adenocarcinoma of the cervix (CCAC) is a rare type of gynecological cancer. The risk factors and pathogenesis have yet to be clearly determined. This is a case report of a 19-year-old woman, who was never exposed to DES from her mother, who had gone for an examination for vaginal bleeding. A polypoid mass measured at 3 cm presenting in her cervix was discovered. Histological diagnosis following cervical biopsy proved the tumor to be a clear cell carcinoma. The patient was then referred to our hospital...

Rationale: brachytherapy is administered in the treatment of patients with locally advanced cervical cancer following chemoradiotherapy. Lack of local anatomy evaluation prior to this procedure might lead to the selection of an inappropriate brachytherapy applicator, increasing the risk of side effects (e.g. uterus perforation, painful procedure ...). Objective: To assess the movement of the uterus and cervix prior to brachytherapy in patients with gynecological cancer, in order to select the proper type of brachytherapy applicator...
