Objectives: The main aims of the study were to investigate the expression of vimentin and its correlation with the overall survival (OS) of patients with malignant ovarian tumors, and the correlation between vimentin expression and tumor stroma characteristics.
Objectives: There is growing evidence that Treg cell infiltration into the cancer nest is associated with poor prognosis. However, the Treg cell population in the peripheral blood may change when a different type of anticancer therapy is applied. Since Treg cells may support tumor growth by enhancing the suppressive profile of the cancer microenvironment, the assessment of Treg cells can bring to light important information regarding prognosis. Thus we decided to analyze the Treg cell population in the peripheral blood in relation to long-term outcomes in the group of patients with ovarian cancer. Material and methods:The 80 patients included in the study were treated surgically followed by chemiotherapy for ovarian cancer between October 2010 through May 2011.The peripheral blood samples from the patients were collected directly prior to chemotherapy. Information on any patients who died was retrieved from the database of the Cuiavia-Pomerania Regional Office of the National Health System of Poland. CD4+CD25+FOXP3+ lymphocytes T were assed by flow cytometry. We have analyzed the long term outcomes of treatment regarding to the level of Treg cells in peripheral blood. Results:We found that patients with serous adenocarcinomas had significantly higher Treg levels compared to those patients with non-serous types. Patients who had a higher percentage of Treg cells within the CD4+ cell population prior to the beginning of the treatment had worse long-term outcomes from the applied therapy. Conclusions:The assessment of Treg levels prior to the start of chemotherapy is clinically useful and may predict overall survival in ovarian cancer patients.
Objectives:The main aim of the study was to evaluate the impact of levels of serum soluble receptor-binding cancer antigen expressed on SiSo cells (sRCAS1) on the overall survival (OS) rates in patients with endometrial cancer. Furthermore, we analyzed sRCAS1 levels according to the clinicopathological characteristics of the disease. Material and methods:The study group comprised 43 patients who were being treated for endometrial cancer. We included 10 low-risk, 20 intermediate-risk and 13 high-risk endometrial cancers using the criteria of the European Society for Medical Oncology (ESMO), the European Society for Radiotherapy & Oncology (ESTRO) and the European Society of Gynaecological Oncology (ESGO). Serum sRCAS1 levels were obtained before and after surgery. Serum sRCAS1 levels were assessed using the ELISA method. Results:In our univariate analysis, both the pre-and post-surgery high sRCAS1 groups of patients with endometrial cancer indicated a shortened OS. However, in our multivariate analysis, when patients' age and disease-related risk was taken into consideration, only the post-surgery sRCAS1 levels remained as independent prognostic factors of a poor OS. Pre-treatment serum sRCAS1 levels were statistically significantly higher than post-surgery sRCAS1 levels; however, the difference between pre-and post-surgery sRCAS1 levels did not influence the patients' OS rate. Pre-and post-surgery sRCAS1 levels did not differ according to tumor grade, stage of the disease or the disease-related risk group. Conclusions:High post-surgery serum sRCAS1 levels seem to be an independent indicator of shortened overall survival in patients with endometrial cancer.
Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) in the United States, and persistent HPV infection has been established as playing a major role in the development of cervical cancer. Providing HPV vaccination and regular screening tests have reduced the risk of developing cervical cancer or helped to detect the cancer at an early stage. Despite the above measures, cervical cancer still remains a major public health problem worldwide. Infection with HPV, and consequently cervical cancer, affects all people with an intact cervix, so not only heterosexual women, but also women from sexual minorities (SMW) together with people assigned female at birth (AFAB). These populations may be even more likely to develop cervical cancer, mainly because they are less likely to be aware of HPV transmission and prevention of cervical cancer. In our review, we summarized the current state of HPV knowledge, collected data assessing the orientation of this issue among SMW and AFAB, and indicated the causes of possible negligence in the prevention of cervical cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
