BACKGROUND: Adenocarcinoma-in-situ (AIS) of the uterine cervix is a precursor to cervical adenocarcinoma and may co-exist with both adenocarcinoma and high-grade squamous dysplasia (cervical intraepithelial neoplasia (CIN) 2 and 3). Up to 60% of AIS lesions are detected incidentally following excisional biopsies performed for the treatment of CIN 2/3. To date there are no data regarding risk factors for persisting or progressive cervical neoplasia in these patients. OBJECTIVE: To investigate patient outcomes following incidentally detected cervical AIS after loop electrosurgical excision procedure (LEEP) or cold knife cone (CKC) biopsy performed for the treatment of high-grade cervical intraepithelial neoplasia (CIN)...

OBJECTIVE: The aim of the study was to identify factors associated with the presence of high-grade squamous intraepithelial lesion (HSIL) at surgical margins of loop electrosurgical excision procedure (LEEP) pathology specimens. MATERIALS AND METHODS: All women evaluated for lower genital tract disease at a single academic institution were prospectively entered into a database. The database was queried for all women who had a LEEP performed for indications within contemporary American Society of Colposcopy and Cervical Pathology guidelines between April 1, 2013, and April 30, 2015...

OBJECTIVE: The management of cervical intraepithelial neoplasia (CIN) and early invasive cancer of the uterine cervix is very difficult to approach, especially in case of young woman who wants to preserve her fertility. Conization of the cervix may have various kinds of disadvantage. The objective of this clinical retrospective study is to investigate the therapeutic effects and clinical efficacy of photodynamic therapy (PDT) including combined chemo-photodynamic therapy in patients with pre-malignant CIN and malignant invasive cervical cancer...

Active surveillance has emerged as an alternative to immediate treatment for men with low-risk prostate cancer. Accordingly, identification of environmental factors that faciliate progression to more aggressive stages is critical for disease prevention. Although calcium-enriched diets have been speculated to increase prostate cancer risk, their impact on early-stage tumors remains unexplored. In this study, we addressed this issue with a large interventional animal study. Mouse models of fully penetrant and slowly-evolving prostate tumorigenesis showed that a high calcium diet dramatically accelerated the progression of prostate intraepithelial neoplasia, by promoting cell proliferation, micro-invasion, tissue inflammation and expression of acknowledged prostate cancer markers...

Ovarian carcinoma represents a heterogeneous group of malignant epithelial tumors which could be divided into two fundamental groups: Type I (endometrioid carcinoma, clear cell carcinoma, low grade serous carcinoma, mucinous carcinoma and more rare seromucinous carcinoma and malignant Brenner tumor) and type II (high grade serous carcinoma - HGSC). HGSC is the most frequent ovarian carcinoma which may be etiologically linked to inactivation of tumor suppressor genes BRCA1/2 and TP53 and differs from type I carcinomas by higher aggressiveness, tendency to peritoneal spread and worse prognosis...

The effects of transforming growth factor beta (TGF-β) signaling on prostate tumorigenesis has been shown to be strongly dependent on the stage of development, with TGF-β functioning as a tumor suppressor in early stages of disease and as a promoter in later stages. To study in further detail the paradoxical tumor-suppressive and tumor-promoting roles of the TGF-β pathway, we investigated the effect of systemic treatment with a TGF-β inhibitor on early stages of prostate tumorigenesis. To ensure effective inhibition, we developed and employed a novel trivalent TGF-β receptor trap, RER, comprised of domains derived from the TGF-β type II and type III receptors...

PURPOSE OF REVIEW: Anal cancer is a serious health problem in HIV-positive men who have sex with men, and precursor lesions, anal intraepithelial neoplasia, are well defined. Given the similarities with cervical cancer, screening for and treatment of anal intraepithelial neoplasia might prevent anal cancer. Screening programmes should meet the Wilson and Jungner criteria. We used these criteria to evaluate the current body of evidence supporting a screening programme for anal dysplasia...

BACKGROUND: Uterine serous endometrial intraepithelial carcinoma (SEIC) is an immediate precursor of invasive carcinoma. The majority of stage IA SEICs are curable, but those with latent peritoneal metastasis and/or capillary lymphatics invasion may have poor prognoses Careful pathologic staging is thus needed to predict the risk of recurrence and to determine postoperative therapeutic strategies. CASE PRESENTATION: A 71-year-old woman was hospitalized for the treatment of peritoneal carcinoma...

BACKGROUND: HIV-positive females are more likely to have abnormal Pap smears than HIV-negative women. These abnormal Pap smears are usually associated with low CD4 cell counts and human papilloma virus infection. MATERIALS AND METHODS: This was a prospective hospital-based study from April 2013 till March 2014. A total of 250 (both symptomatic and asymptomatic) HIV-positive females were examined in Gynaecology OPD at R.C.S.M. G.M.C and C.P.R. Hospital, Kolhapur, and their cervical smears were taken...

In this study, the potential price for a therapeutic vaccine against Human Papilloma Virus (HPV)-16 & 18 (pre)-malignant cervical lesions is examined. A decision tree model was built in the context of the new Dutch cervical cancer-screening program and includes a primary test for the presence of HPV. Based on data of cervical cancer screening and HPV prevalence in the Netherlands, cohorts were created with HPV-16 or 18 positive women with cervical intraepithelial neoplasia (CIN) 2 or 3 or cervical cancer stage 1A (FIGO 1A)...

Introduction: Anal carcinoma represents an increasing problem in HIV-infected patients. Anal intraepithelial neoplasia (AIN), the precursor lesion, is currently diagnosed by high-resolution anoscopy (HRA) using optical magnification derived from gynecological colposcopy. This prospective study evaluates anal chromoendoscopy (ACE) using standard gastroenterological video-endoscopes in diagnosing AIN. Methods: After clinical examination, proctoscopy and surface staining with acetic acid followed by Lugol's solution, ACE was performed with a mucosectomy cap on the tip of the endoscope...

The impact of technical feed treatment and diet on stomach lesions and traits of the local and systemic immune system were investigated in fattening pigs. Feeding groups differed in technical feed treatment (standard ground meal vs. finely ground and pelleted feed) and diet (soya bean meal vs. rapeseed meal/DDGS/soya beans). Pigs were fattened approximately 10 weeks by ad libitum feeding and slaughtered subsequently. Gastric alterations were assessed by a macroscopic scoring system [macroscopic stomach score (MSC) 0 =  normal to 4 =  severe lesions]...

REVIEW
Peter V Chin-Hong
Human papillomavirus (HPV) is a common infection in kidney transplant recipients. HPV causes cervical, anal, vulvar, vaginal, penile and head and neck cancers. Kidney transplant recipients have a disproportionate burden of disease given prolonged immunosuppression. Given the long pre-invasive state of precancer lesions such as cervical intraepithelial neoplasia (CIN) and anal intraepithelial neoplasia (AIN) most HPV-cancers are preventable with screening and targeted treatment of disease. Pre-transplant vaccination of age-eligible kidney transplant recipients is otherwise ideal...

PURPOSE: Radiofrequency ablation (RFA) effectively treats esophageal high-grade dysplasia, but its efficacy in treating anal canal high-grade squamous intraepithelial lesions (HSILs) is unsubstantiated. This prospective study assessed the safety and efficacy of applying hemi-circumferential RFA to anal canal HSIL. METHODS: Twenty-one HIV-negative participants with HSIL occupying ≤ half the anal canal circumference were treated with hemi-circumferential anal canal RFA...

OBJECTIVE: To evaluate the reproducibility and accuracy of the HPV16/18-E6 test. METHODS: The study population was comprised of 448 women with a previously abnormal Pap who were referred to the Barretos Cancer Hospital (Brazil) for diagnosis and treatment. Two cervical samples were collected immediately before colposcopy, one for the hr-HPV-DNA test and cytology and the other for the HPV16/18-E6 test using high-affinity monoclonal antibodies (mAb). Women with a histologic diagnosis of cervical intraepithelial neoplasia grade 2 or 3 were considered to be positive cases...

PURPOSE: To describe clinical presentation and histopathological features of a nodulo-ulcerative variant of ocular surface squamous neoplasia (OSSN). METHODS: Retrospective study. RESULTS: Six patients were identified with a nodulo-ulcerative variant of OSSN. Mean age at presentation was 56 years. One patient was immunosuppressed because of human immunodeficiency virus infection. The initial misdiagnosis was necrotizing scleritis/sclerokeratitis (n = 4), intraepithelial neoplasia (n = 1), and chalazion (n = 1)...

p16(INK4a) (p16) tumor-suppressor protein is a biomarker of human papillomavirus (HPV) oncogenic activity that has revealed a high rate of positivity in histological high-gade squamous intraepithelial lesion/cervical intraepithelial neoplasia grade 2 (HSIL/CIN2) lesions. However, there is a paucity of data regarding p16 status as a surrogate marker of HSIL/CIN2 evolution. The aim of this study was to evaluate the outcome of HSIL/CIN2 patients followed up without treatment for 12 months according to p16 immunohistochemical staining...
