In recent years it has become clear that many extra-uterine (pelvic) high-grade serous carcinomas (serous carcinomas) are preceded by a precursor lesion in the distal fallopian tube. Precursors range from small self-limited 'p53 signatures' to expansile serous tubal intraepithelial neoplasms that include both serous tubal epithelial proliferations (or lesions) of uncertain significance and serous tubal intraepithelial carcinomas. These precursors can be considered from three perspectives. The first is biologic underpinnings, which are multifactorial, and include the intersection of DNA damage with Tp53 mutations and disturbances in transcriptional regulation that increase with age...

In the developed world, the incidence of cervical squamous cell carcinoma has decreased, however, the incidence of adenocarcinoma in situ (AIS) and invasive adenocarcinoma increased, predominantly in young females. The goal of this study was to evaluate the most recent incidence rates of AIS, adenocarcinoma, and squamous cell carcinoma of the uterine cervix in the Netherlands in 2004-2013. By using Dutch national pathology and cancer registries, we calculated European standardized incidence rates (ESR) and estimated annual percentage changes (EAPC) for AIS during 2004-2013 and for invasive cervical carcinomas during 1989-2013...

Cancer of the uterine cervix (CACX) is one of the most common carcinoma affecting women worldwide. During treatment, histologically lymph node (LN) metastasis and presence of HPV DNA in blood plasma act as a major prognostic factor. Despite the lack of apparent LN involvement, some early-invasive CACX patients have shown recurrences and poor survival. This is suggestive of undetected early dissemination of cancer cells characterized by presence of HPV DNA in histologically non-metastatic LNs which finally progresses into histologically visible metastasis...

Uterine carcinoma of the lower uterine segment (LUS) is a rare tumor that accounts for 3-3.5% of cases of uterine malignant cancer. The tumor arises from the lower region of the uterine body through the upper region of the cervix. The present study reported a case of clear cell carcinoma that originated from the LUS. A 50-year-old woman visited a local hospital due to irregular vaginal bleeding. She was suspected to have a uterine tumor and was referred to Tachikawa Hospital (Tokyo, Japan). Transvaginal ultrasound and magnetic resonance imaging revealed a uterine tumor from the lower region of the uterine body through the upper region of the cervix...

Uterine carcinosarcoma (UCS) is a form of endometrial cancer simultaneously exhibiting carcinomatous and sarcomatous elements, but the underlying molecular and epigenetic basis of this disease is poorly understood. We generated complete DNA methylomes for both the carcinomatous and the sarcomatous components of three UCS samples separated by laser capture microdissection and compared DNA methylomes of UCS with those of normal endometrium as well as methylomes derived from endometrioid carcinoma, serous endometrial carcinoma, and endometrial stromal sarcoma...

OBJECTIVES: The role of pelvic lymphadenectomy (LA) in women with stage I endometrial carcinoma (EC) is controversial. The objective of this study is to investigate the prognostic impact of LA on survival endpoints in matched cohorts of women with stage I EC solely of endometrioid histology. Survival endpoints included recurrence-free (RFS), disease-specific (DSS) and overall survival (OS). METHODS AND MATERIALS: Patients with FIGO stage I EC who underwent hysterectomy with LA as part of their surgical staging between 1/1990 and 6/2015 were matched to a similar group that underwent hysterectomy without lymphadenectomy (NLA), based on stage, grade and adjuvant management...

OBJECTIVES: The aim of this study was to evaluate if older age alone negatively impacts survival endpoints in women with early-stage uterine endometrioid carcinoma (EC), or its reported prognostic impact is due to an interaction with other well-known adverse factors using matched-analysis methodology. METHODS: We identified 1254 patients with International Federation of Gynecology and Obstetrics stage I-II EC who underwent hysterectomy at our institution. We created 2 matched groups based on International Federation of Gynecology and Obstetrics stage, tumor grade, lymph node dissection status, and the type of adjuvant management...

A 72-year-old male (height: 160 cm, weight: 53 kg) was scheduled to undergo left renal and male with ans uterine tract resection. The patient had previously undergone right radical maxillofacial surgery with orbital exenteration 14 years before the present operation to treat squamous cell carcinoma of the right maxillary sinus, with tumour invasion to the orbital floor. An anaesthesiologist encountered difficulty in performing mask ventilation during the induction of anaesthesia in the patient, despite a good mask fit on the face, because the adhesive tape around the orbit had moved...

Neuroendocrine tumors (NETs) are aggressive diseases developing from neuroendocrine cells that most frequently involve the gastro-entero-pancreatic tract and the lung, but more rarely are found in almost all body tissues. Limited biological and clinical data are currently available for NETs in uncommon sites, such as female genital tract. NETs represent 0.9% to 1.5% of the tumors of the uterine cervix. They are more likely to have lymph-vascular space invasion and lymph node involvement, and to develop local and distant relapses when compared with the mostly common cervical squamous cell carcinomas or adenocarcinomas...

Targeted therapies in endometrial cancer (EC) using kinase inhibitors rarely result in complete tumor remission and are frequently challenged by the appearance of refractory cell clones, eventually resulting in disease relapse. Dissecting adaptive mechanisms is of vital importance to circumvent clinical drug resistance and improve the efficacy of targeted agents in EC. Sorafenib is an FDA-approved multitarget tyrosine and serine/threonine kinase inhibitor currently used to treat hepatocellular carcinoma, advanced renal carcinoma and radioactive iodine-resistant thyroid carcinoma...

Screening for uterine cervical intraepithelial neoplasia (CIN) followed by aggressive treatment has reduced invasive cervical cancer (ICC) incidence and mortality. However, ICC cases and carcinoma in situ (CIS) continue to be diagnosed annually in the United States, with minorities bearing the brunt of this burden. Because ICC peak incidence and mortality are 10-15 years earlier than other solid cancers, the number of potential years of life lost to this cancer is substantial. Screening for early signs of CIN is still the mainstay of many cervical cancer control programs...

BACKGROUND: Uterine serous carcinoma (USC) shows greater morphological, clinical and molecular similarities to high-grade ovarian tubal serous carcinoma than to other types of endometrial cancer. As high-grade ovarian tubal serous carcinoma is known to be associated with BRCA1/2 pathogenic germline mutations (PMs), we aimed to explore whether USC is also a constituent of hereditary breast and ovarian cancer syndrome. METHODS: Pubmed, EMBASE and Web of Science were searched in July 2016 for articles assessing the association between USC and germline BRCA1/2-PMs...

BACKGROUND: The management of uterine-serous-carcinoma (USC) no longer amenable to treatment with surgery, radiation and/or chemotherapy remains dismal. Alternative therapeutic options are desperately needed. CASE: We describe the case of a heavily pretreated 74-year-old patient with a recurrent USC overexpressing HER2/neu at 3 + level by IHC treated with the anti-HER2/neu antibody-drug-conjugate (ADC) trastuzumab-emtansine (TDM-1-Kadcyla-Genentech/Roche). She experienced a remarkable clinical response to TDM-1 with a complete resolution of a large metastatic, radiation/chemotherapy resistant tumor deposit in her abdominal wall muscle confirmed by multiple CAT scans and a prolonged systemic control of her disease...

INTRODUCTION: The immune system plays a critical role in the defense against human papillomavirus (HPV) infection and its persistence. Toll-like receptors (TLRs) are membrane receptors responsible for activation of the innate immune response, and an association between TLR expression and uterine cervical cancer has been shown. Tumor necrosis factors (TNFs) are among the main mediators of skin and mucosa inflammation. The aim of this study was to demonstrate the association between TLR and TNF immune expression and cervical cancer and premalignant cervical lesions...

Cisplatin is a classic chemotherapeutic agent widely used to treat different types of cancers including ovarian, head and neck, testicular and uterine cervical carcinomas. However, cisplatin induces acute kidney injury by directly triggering an excessive inflammatory response, oxidative stress, and programmed cell death of renal tubular epithelial cells, all of which lead to high mortality rates in patients. In this study, we examined the protective effect of protocatechuic aldehyde (PA) in vitro in cisplatin-treated tubular epithelial cells and in vivo in cisplatin nephropathy...
