A poorly differentiated synovial sarcoma (SYT/SSX1) expresses neuroectodermal markers: a xenografts and in vitro culture study.
Synovial sarcoma (SS) is a neoplasm that poses diagnostic problems, due to its histologic heterogeneity. The poorly differentiated variant, in particular, may be histologically indistinguishable from other small round cell tumors. Detection of the synovial sarcoma-associated t(X;18) or SYT-SSX fusion transcripts may be necessary to confirm the diagnosis of SS in difficult cases. Most of SS carry a t(X;18) in about one third of cases as the sole cytogenetic abnormality. We evaluated a case of poorly differentiated synovial sarcoma and their derived tumors in nude mice xenografts and cell cultures. We used a panel of antibodies (including those to intermediate filament, nerve-sheath associate…
Human papillomavirus genotype distribution in cervical cancer cases in Spain. Implications for prevention
Objective. Human papillomavirus (HPV) genotype distribution in invasive cervical cancer (ICC) is critical to guide the introduction and to assess the impact of HPV prophylactic vaccines. This study aims to provide specific information for Spain. Methods. 1043 histological confirmed ICC cases diagnosed from 1940 to 2007 from six Spanish regions were assembled. HPV DNA detection was performed by SPF10 broad-spectrum PCR followed by deoxyribonucleic acid enzyme immunoassay and genotyping by reverse hybridization line probe assay (LiPA(25)) (version 1). Results. Of 1043 ICC cases, 904 were HPV DNA positive (adjusted prevalence: 89.1%). The eight most common types, in decreasing order, were HPV …
