Alterations of the retinoblastoma (Rb) gene have been described in several human neoplasms and recently, it has been suggested that these alterations may play a role in the development of endometrial carcinomas. Paraffin sections from 31 cases of normal endometrium (16 proliferative, 15 secretory), 35 hyperplastic lesions and 89 endometrial carcinomas were investigated immunohistochemically for...
The relation between hypertension and the risk of selected hormone-related neoplasms in women was investigated in a network of case-control studies conducted in Italy during 1983-1996. Cases were women younger than 75 years with histologically confirmed cancer of the breast (n=3406), endometrium (n=745), ovary (n=970), and thyroid (n=145). Controls were 3054 women admitted in the same geographi...
objective: endometriosis is a common disease in which the endometrial stroma and glands grow abnormally outside the uterine cavity. the establishment of animal models can be effective for determining the etiology of endometriosis. in this study we compare two endometriosis models using endometrial fragments and isolated cultured endometrial cells. methods: we obtained endometrial tissues that ...
spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...
The E2F group of transcription factors transactivates genes that promote progression through the G1-S transition of the cell cycle. Members of the retinoblastoma (Rb) family of proteins bind to E2Fs and inhibit this function. E2F-4, one example of the E2F group, functions as an oncogene when transfected into nontransformed cells in vitro. On the other hand, mice that are homozygously lacking a ...
BACKGROUND Sedentary behavior is ubiquitous in modern adults' daily lives and it has been suggested to be associated with incident cancer. However, the results have been inconsistent. In this study, we performed a systematic review and meta-analysis of prospective cohort studies to clarify the association between sedentary behavior and incident cancer. METHOD PubMed and Embase databases were ...
Ovary is one of the main endocrine glands, also the source of female fertility and at the same time the organ with the largest number of histological varieties of malignant tumors. The most frequent among primary neoplasms are epithelial tumors. Secondary tumors of the ovary arise by direct tumor extension from adjacent organs or tissues, by transtubal or transperitoneal route, as well as hemat...
STUDY QUESTION Is the endometrial mononuclear cell population in infertile patients altered in subjects with classical endometrial polyps (macropolyps) versus endometrial micropolyps that are hysteroscopically recognized as small uterine cavity protrusions? SUMMARY ANSWER Macropolypoid endometrium had a low density of pan-leukocytes, pan-T cells and natural killer (NK) cells, whereas micropol...
INTRODUCTION Endometrial hyperplasia represents a diversified set of disorders which has challenged pathologists for decades. Due to its high likelihood of progression to carcinoma, endometrial intraepithelial neoplasia (EIN) demands prompt and specialized intervention. MATERIALS AND METHODS This 15-month (September 2014 - November 2015) retrospective analysis involved 258 cases of female pat...
BACKGROUND p16 has been reported to disappear by hypermethylation in various cancers. However, the relationship between the frequency of hypermethylation of p16 and the mechanism of its inactivation has not been completely elucidated in endometrial cancer. MATERIALS AND METHODS Hypermethylation in the promoter region of the p16 gene and the expression of the p16 protein in 51 specimens, inclu...
