INTRODUCTION: The biological behavior of cancer cells is influenced by the tumor microenvironment in which they develop. In this context, stressor stimuli such as hypoxia are considered critical for tumor development and therapeutic management. Cellular response to various stimuli is evidenced in the activation of intracellular signaling pathways such as JAK/STAT, which is one of the most important for its effects in differentiation and cell proliferation. OBJECTIVE: To evaluate the condition of the JAK/STAT pathway through the expression/activation of the STAT3 protein in cervix cancer cells (HeLa) and endothelial cells (EA...

BACKGROUND: Based on ontogenetic-anatomic considerations, we have introduced total mesometrial resection (TMMR) and laterally extended endopelvic resection (LEER) as surgical treatments for patients with cancer of the uterine cervix FIGO stages I B1 - IV A. For a subset of patients with locally advanced disease we have sought to develop an operative strategy characterized by the resection of additional tissue at risk for tumor infiltration as compared to TMMR, but less than in LEER, preserving the urinary bladder function...

Cervical carcinoma is the fourth most common cause of death in woman, caused by human papillomavirus (HPV) infections and arising from the cervix. Cytoskeleton-associated protein 2 (CKAP2), also known as tumor-associated microtubule-associated protein, has been linked to tumorigenic effects. In the present study, we screened CKAP2 as a new candidate gene which promotes development of cervical carcinoma, in two independent datasets (TCGA and GSE27678). Results showed that CKAP2 expression was significantly up-regulated in cervical cancerous tissues compared with normal counterparts...

The current recommended treatment for stage Ia2 cervical cancer is a radical or modified radical hysterectomy. Although in the United States the incidence of cervical cancer is low and declining, almost 50% of the over 4,000 new cases will present in early stages. An estimated 2,200 women each year will undergo radical hysterectomy and many will suffer from both early- and late-onset complications. The purpose of this review is to examine if there is still a role for radical hysterectomy in the proper treatment of stage Ia2 cervical cancer given most recent data...

REVIEW
Elizabeth R Burton, Joel I Sorosky
An update on the current epidemiology and a review of the risk factors of cervical and endometrial cancers are discussed. Cervical cancer prevention with a focus on human papillomavirus vaccination and cervical cancer screening is reviewed, emphasizing the new focus of less frequent intervention in an effort to maintain high rates of early detection of disease while decreasing unnecessary and anxiety-provoking colposcopies, biopsies, and excisional procedures. The replacement of traditional endometrial hyperplasia terminology with more relevant clinical categories, with an emphasis on the introduction of endometrial intraepithelial neoplasia, is presented...

Verrucous carcinoma (VC) is a very rare variant of squamous cell carcinoma of the cervix, difficult to point out in histology because of its benign appearance. We present the case of a 29-year-old woman with a locally advanced cervical VC who underwent radiotherapy followed by radical hysterectomy. After local relapse and despite pelvic exenteration, her condition deteriorated. Treatment of choice in VC is surgery, because of the risk of anaplastic transformation under irradiation, raising the chances of distant spread and converting this rather benign-like type of cancer to an aggressive cancer...

The role of connexin proteins (Cx), which form gap junctions (GJ), in progression and chemotherapeutic sensitivity of cervical cancer (CaCx), is unclear. Using cervix specimens (313 CaCx, 78 controls) and CaCx cell lines, we explored relationships among Cx expression, prognostic variables and mechanisms that may link them. In CaCx specimens, Cx32 was upregulated and cytoplasmically localized, and three other Cx downregulated, relative to controls. Cx32 expression correlated with advanced FIGO staging, differentiation and increased tumor size...
