We evaluated the efficacy of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine in preventing HPV-related disease after surgery for cervical lesions in a post-hoc analysis of the PApilloma TRIal against Cancer In young Adults (PATRICIA; NCT00122681). Healthy women aged 15-25 years were randomized (1:1) to receive vaccine or control at months 0, 1 and 6 and followed for 4 years. Women ...
The objective of the study was to compare three methods of monitoring the inhibition by dietary theaflavins of N-nitrosomethylbenzylamine (NMBA)-induced rat esophageal intraepithelial neoplasia: the mean tile grade, measured by computer-assisted quantitative image tile analysis; tumor multiplicity; and mean tumor size. A "tile" is defined as a small portion of a microscopic image at x 40, 87 x ...
Chromosome counts and karyotypes were prepared from samples of dysplasia and carcinoma in situ of the uterine cervix in 14 patients with the use of tissue culture technics. The material for initial culture was identified as neoplastic epithelium in vivo by colpomicroscopy. Then a biopsy was obtained from within this area; one half was fixed for histologie examination, and in the remaining half,...
INTRODUCTION Vaginal intraepithelial neoplasia (VAIN) is a pre-malignant lesion, potentially leading to vaginal cancer. It is a rare disease, representing less than 1% of all intraepithelial neoplasia of the female genital tract. Similar to cervical intraepithelial neoplasia (CIN), there are three different grades of VAIN. VAIN 1 is also known as a low-grade squamous intraepithelial lesion (LSI...
Gallbladder polyps are frequently found on abdominal ultrasonography. Most gallbladder benign. However, the risk of malignancy increases when polyp size exceeds 10 mm. The fifth edition World Health Organization Classification tumors proposed three types preinvasive neoplasms gallbladder: adenoma, intracholecystic papillary neoplasm (ICPN), and biliary intraepithelial neoplasia (BilIN). Herein,...
Cervical intraepithelial neoplasms The cervical intraepithelial neoplasms (CINs) are abnormalities of the squamous ectocervical epithelium. The first group consists of squamous intraepithelial lesions of low histological stage (LSIL) and includes flat condyloma and CIN I, while the second group consists of squamous intraepithelial lesions of high histological stage (HSIL) including CIN II and C...
purpose: to report the clinical and histopathological features of recurrent atypical fibrous histiocytoma of the corneo-scleral limbus followed by intra-epithelial squamous neoplasia. case report: a 25-year-old female patient presented with a recurrent vascularized gelatinous mass in the left nasal limbus. the preliminary histopathological diagnosis of the previously excised lesion was an amela...
PURPOSE The aim of this study was to evaluate the human papillomavirus genotypes and the frequency of multiple human papillomavirus infections, as well as to assess the association between human papillomavirus genotype, cyto-histopathological abnormalities and age range. METHODS A retrospective cross-sectional study was carried out between June 2010 and October 2013 in Salvador, Bahia, Brazil...
Biliary intraepithelial neoplasia (BilIN) is a precursor lesion of hilar/perihilar and extrahepatic cholangiocarcinoma. BilIN represents the process of multistep cholangiocarcinogenesis and is the biliary counterpart of pancreatic intraepithelial neoplasia (PanIN). This study was performed to clarify the histological characteristics of BilIN in relation to PanIN. Using paraffin-embedded tissue ...
