Endometrial cancer is the most common malignancy of the female genital tract in industrialized countries. The traditional treatment of endometrial cancer is based on a surgical approach. In recent years, systemic endocrine therapy has demonstrated good efficacy in recurrent or metastatic setting, delaying progression, ameliorating quality of life and palliating symptoms. Areas covered: Phase I and II studies on selective estrogen receptor down-regulators used for the treatment of endometrial cancer treatment have been reviewed. The pharmacokinetic and pharmacodynamic features of selective receptor down-regulators have been also investigated. Expert opinion: Selective estrogen receptor down-regulators may exhibit clinical efficacy in the treatment of gynecological malignancies due to their pure estrogen receptor antagonist properties. However, up to now data are still limited and some unsolved questions remain. Fulvestrant has poor oral bioavailability and low pharmacodynamic characteristics. Further trials are required to examine new selective estrogen receptor down-regulator agents with better pharmacodynamic and pharmacokinetic profiles.

ObjectivesDiagnosis of HPV infection is usually performed from cervical liquid-based cytology specimens (LBC), but these often contain a large amount of human papillomavirus (HPV) genotypes, most of which might cause transient infections. The aim of the study was to evaluate the performance of BD Onclarity HPV test genotyping method on formalin-fixed, paraffin-embedded (FFPE) cervical specimens compared with genotyping results from LBC.Materials and MethodsFormalin-fixed, paraffin-embedded specimens from women surgically treated for cervical intraepithelial lesions (CINs) at the European Institute of Oncology, Milan, from September 2012 to June 2013 were retrieved from the archives of the Department of Pathology of the European Institute of Oncology. The FFPE and LBC specimens were genotyped using the same extended genotyping Onclarity assay.ResultsWe collected 99 samples (26 CIN 1, 30 CIN 2, and 43 CIN 3+), but 15 were excluded from the analysis: these 84 samples show an overall agreement of 89% for HPV status between FFPE Onclarity samples versus LBC samples. The FFPE and LBC samples showed identical genotype in 75% samples, compatible genotype (at least 1 of the genotypes detected in LBC sample was found in the tissue sample) in 14% specimens, and discrepant genotype in 11% samples.ConclusionsOur data demonstrate a very good concordance between HPV genotypes found in cytological and tissue samples, suggesting that the Onclarity method could also be used to detect HPV in tissue samples and that the HPV genotype detected in FFPE samples is one of the HPV detected in cytological samples, supporting the thesis that one lesion is caused by one HPV genotype.
