The rising global incidence of uterine cancer is linked to the escalating prevalence of obesity. Obesity results in alterations in adipocytokines and IGFs, driving cancer progression via inflammation, increased cell proliferation, and apoptosis inhibition, although the precise mechanisms are still unclear. This study examined a set of six markers, namely, adiponectin, leptin, IL6, TNFα, IGF1, and IGF2 and compared them between fifty age-matched endometrial cancer patients (study group) and non-cancer patients with benign gynaecological conditions (control group).

Chronic inflammation has been closely linked to the development and progression of various cancers. The epithelial-mesenchymal transition (EMT) is a process involving the acquisition of mesenchymal features by carcinoma cells and is an important link between inflammation and cancer development. Inflammatory mediators in the tumour micro-environment, such as cytokines and chemokines, can promote EMT changes in cancer cells.

The objective of the study was to document the effect of adipocytokines on endometrial cancer progression. A search of the databases CINAHL, Medline, PubMed, Cochrane, Web of Science, Embase and Google Scholar was performed for English language articles from January 2000 to December 2020 using the keywords: (Endometrial cancer) AND (progression OR metastasis) AND (adipocytokine OR adiponectin OR leptin OR visfatin OR IL-6 OR TNF-α OR adipokine OR cytokine). Forty-nine studies on adipocytokines have been included in this review.

Objective: To investigate the association between circulating levels of adipocytokines (adiponectin, leptin, tumour necrosis factor alpha (TNFα), interleukin 6 (IL-6)) and growth factors (insulin-like growth factor I (IGF-I) and II (IGF-II)), and the risk of endometrial cancer.

Methods: Cochrane, CINAHL, Embase, Medline and Web of Science were searched for English-language manuscripts published between January 2000 and August 2018 using the following string of words: cancer and endometrial and (obesity or BMI) and (adiponectin or TNF* or IGF-I or IGF-II or IL-6 or leptin).

Results: Twenty articles were included in this meta-analysis, which corresponded to 18 studies involving 2921 endometrial carcinoma cases and 5302 controls.

Our understanding of the pathogenesis of Paget's disease of the vulva and the breast remains limited. Current evidence supports the fact that angiogenesis plays an important role in the pathogenesis of several diseases. Therefore, we sought to define its role, as correlated with microvessel density, in Paget's disease of the vulva and the breast.

Objectives: The growing prevalence of endometrial cancer has made it necessary to characterize its molecular and clinical properties and to develop new strategies in treating this disease. A number of molecular and genetic events have been observed in endometrial cancers, which have enabled us to have a better understanding of the biology and development of the disease. For example, PTEN/AKT pathway and its downstream targets and the mTOR (mammalian target of rapamycin) pathway have been shown to play an important role in endometrial cancer pathogenesis.

Aims: Loss of retinoblastoma protein expression and overexpression of cyclin D1 have been implicated in the development and progression of some cancers. Paget's disease of the vulva (PDV) and Paget's disease of the breast (PDB) are uncommon conditions and the pathogenesis of these diseases is still unclear. The aim was to examine the expression of the retinoblastoma and cyclin D1 proteins in PDV and PDB and to correlate any differences between PDV and PDB, and in the presence or absence of an underlying carcinoma.

The growth and metastasis of many cancers is due in part to loss of cell-cell adhesion. E-cadherin, plakoglobin and beta-catenin are important in cell adhesion. Our aim was to examine the presence of these molecules in Paget's disease of the vulva and Paget's disease of the breast, and to correlate any differences in their expression with the presence of invasive disease or an underlying carcinoma.

Paget's disease of the vulva is an uncommon lesion, and gynaecologists and dermatologists generally have limited experience in its management. The British Society for the Study of Vulval Disease has established a register of cases, and we present a review of 76 cases registered to date. The majority of patients were treated by surgical excision and reconstruction, but non-surgical therapies are an option.

Background: Paget's disease of the vulva and the breast are uncommon conditions. The pathogenesis underlying these diseases is still unclear. Vascular endothelial growth factor-A (VEGF-A), a potent angiogenic factor, has been demonstrated in a variety of tumour cell types and is thought to be involved in tumour expansion.
