The FIGO staging system has undergone many modifications since it first appeared in about the middle of the previous century. Due to the use of modern diagnostic tools, namely computed tomography, magnetic resonance imaging, positron emission tomography, sentinel lymph node biopsy and of neoadjuvant chemotherapy, certain gynecological cancer cases cannot be allocated to a specific stage if one wishes to adhere strictly to FIGO requirements. In these circumstances such cases remain actually unstaged. This should prompt appropriate modifications of the current FIGO staging system so that it fulfills its aims...

Persistent infection with high-risk human papillomavirus (hrHPV) is a key step in the development of cervical cancer. However, making clinical decisions about how to deal with these cases has become a challenge for obstetrics and gynecology (Ob/Gyn) practitioners. Here, we review the latest research findings and propose possible solutions for the management of persistent hrHPV infections.

Endometrial cancer is the most common gynecologic malignancy, about 80% of which is endometrial endometrioid carcinoma. Dysregulation of spindle assembly checkpoint plays a vital role in endometrial endometrioid carcinoma tumorigenesis and progression. The purpose of this study was to explore how tyrosine threonine kinase, a spindle assembly checkpoint-related protein, promotes the endometrial endometrioid carcinoma progression. We found that both messenger RNA and protein levels of tyrosine threonine kinase in endometrial endometrioid carcinoma tissues are higher than those in normal endometrial tissues, and its expression is associated with tumor stages...

Ovarian cancer is the most lethal gynecologic malignancy, due to its high propensity for metastasis. Cancer-associated fibroblasts, as the dominant component of tumor microenvironment, are crucial for tumor progression. However, the mechanisms underlying the regulation of ovarian cancer cells by cancer-associated fibroblasts remain little known. Here, we first isolated cancer-associated fibroblasts from patients' ovarian tissues and found that cancer-associated fibroblasts promoted SKOV3 cells' proliferation, migration, and invasion...

Endometriosis may be a definitive risk factor for ovarian cancer, the most fatal gynecological cancer. The ability of endometriosis to transform into malignancy, first described by Dr. Sampson in 1925, is considered a rare occurrence, affecting approximately 1% of ovarian endometriomas. Recently we conducted a retrospective study regarding the malignant transformation of endometriosis in Japanese women. Many studies have reported a consistent correlation between endometriosis and ovarian cancer according to histological subtypes...

PURPOSE: To provide evidence-based, resource-stratified global recommendations to clinicians and policymakers on the management and palliative care of women diagnosed with invasive cervical cancer. METHODS: ASCO convened a multidisciplinary, multinational panel of cancer control, medical and radiation oncology, health economic, obstetric and gynecologic, and palliative care experts to produce recommendations reflecting resource-tiered settings. A systematic review of literature from 1966 to 2015 failed to yield sufficiently strong quality evidence to support basic- and limited-resource setting recommendations; a formal consensus-based process was used to develop recommendations...

Cervical cancer is one of the most frequently diagnosed cancers and is a major cause of death from gynecologic cancers worldwide; the cancer burden from cervical cancer is especially heavy in less developed countries. Most cases of cervical cancer are caused by persistent infection with carcinogenic human papillomavirus (HPV) genotypes 16 and 18. Non-resolving inflammation caused by HPV infection provides a microenvironment that facilitates cancer development. Molecular alterations during the process of HPV-induced carcinogenesis are characterized by DNA methylation within the HPV genome, promoter hypermethylation of tumor suppressor genes in the host genome, as well as genomic instability caused by viral DNA integrating into the host genome...

Ovarian cancer is the most lethal gynecological malignancy in the world. Our previous studies showed that mangiferin, purified from plant source, possessed anti-neoplasm effect on human lung adenocarcinoma A549 cells. This study aimed to determine the apoptosis-inducing effect of mangiferin on human ovarian carcinoma OVCAR3 cells. By in vitro studies, we found mangiferin significantly inhibited viability of OVCAR3 cells, and remarkably increased the sensitivity of OVCAR3 cells to cisplatin. In addition, the activation of caspase-dependent apoptosis was observed in mangiferin treated ovarian cancer cells...

Gynecological cancer is difficult to be diagnosed at early stages. The relatively high mortality rate has been a serious issue accordingly. We herein reported a diagnosis method by using circulating tumor cells (CTCs) which have been extensively explored as a potential tool for diagnostics and prognostics of ovarian cancers. Nonetheless, the detection of CTCs still remains a challenge because of the difficulty in isolating them from whole blood samples since they are shed into the vasculature from primary tumors and circulate irregularly in the bloodstream in extremely low concentrations...

The Acute Colonic Pseudo-Obstruction (ACPO), also known as Ogilvie's syndrome, is defined by a poor peristaltic activity of the colon that mimics mechanical obstruction in the absence of any mechanical occlusive gut lesion. This case report is the first to be published on ACPO following a robotic- assisted radical hysterectomy. Since robotic-assisted laparoscopic surgery has become the next major stage of advancement for a range of operations especially in gynecologic oncology surgery, this report emphasizes the importance of recognizing precipitating factors associated with this syndrome, including minimally invasive surgery...

: Cervical cancer is one of the most common cancers among women worldwide, and more than 85% of the disease occurs in low- and middle-income countries. Although it ranks as the most common cancer in Ghanaian women, there are no data available on cervical cancer survival. METHODS: Information on women with a diagnosis of cervical cancer from 2010 to 2013 was collected from the Komfo Anokye and Korle-Bu Teaching Hospitals through review of paper-based and electronic medical records (including pathology records) at the oncology units and the departments of obstetrics and gynecology...

Aberrant histone methylation contributes to the progression and development of many tumors. Histone methylation is a dynamic process regulated by both histone demethylase and histone methyltransferase, which ultimately alters the levels of gene transcription. However, the relationship between histone demethylase and histone methyltransferase, as well as their regulatory mechanisms in ovarian cancer development, is still unclear. Lysine-specific demethylase 2B (KDM2B) is a key demethylase of H3K36me3 and H3K4me3 that regulates gene expression and plays a role in tumorigenesis via epigenetic mechanisms...

Ovarian cancer is the most lethal form of all gynecologic malignancies. The presenting clinical symptoms of ovarian cancer are very vague and often appear late in the course of disease. Hence, most patients are diagnosed at later stages. At present, there is no effective screening of ovarian cancer. Primary prevention could be considered a strategy to decrease the mortality from ovarian cancer, not only in women at high risk but also in those at low risk. Most "ovarian cancers," and more specifically the high-grade serous carcinoma (HGSC) subtype of ovarian cancer, actually could originate in the fallopian tube...

BACKGROUND: Epithelial ovarian cancer (EOC) remains the most lethal gynecologic malignancy. The objective of this study was to compare the anti-tumor activity of HER2/neu-targeting monoclonal antibodies, trastuzumab (T), pertuzumab (P), combination of trastuzumab and pertuzumab (T+P) and trastuzumab-emtansine (T-DM1) in EOC with high HER2/neu expression. METHODS: Primary EOC cell lines were established and cell blocks were analyzed for HER2/neu expression. Cytostatic, apoptotic and antibody-dependent cell-mediated cytotoxicity (ADCC) activities of T, P, T+P and T-DM1 were evaluated in vitro...

OBJECTIVES: Nerve-sparing radical hysterectomy for early stage cervical cancer was introduced to improve quality of life after treatment. Sparing the pelvic autonomic nerves reduces bladder, bowel, and sexual dysfunction. The Leiden nerve-sparing radical hysterectomy (LNSRH) was modified to the Swift procedure, the latter being more radical regarding the sacrouterine and parametrial resection. We investigate whether nerve-sparing surgery has comparable oncological outcomes as the conventional radical hysterectomy (CRH)...
