The assumption that intestinal metaplasia is a prerequisite for intraepithelial neoplasia/dysplasia and adenocarcinoma in the distal esophagus has been challenged by observations of adenocarcinoma without associated intestinal metaplasia. This study describes our experience of intestinal metaplasia in association with early Barrett neoplasia in distal esophagus and gastroesophageal junction. We reviewed the first endoscopic mucosal resection of 139 patients with biopsy-proven neoplasia. In index endoscopic mucosal resection, 110/139 (79%) cases showed intestinal metaplasia...

Background: Historically the conventional Pap smear has been an effective screening tool for Carcinoma cervix. However the reporting of benign and malignant endometrial cells on Pap smear has remained controversial. There are very few studies addressing the utility of Pap smears in diagnosing endometrial carcinomas. Objective: To rescreen the Pap smears of patients with endometrial adenocarcinoma for the detection of normal/ atypical endometrial cells and to correlate with clinico-pathological parameters. Methods: The present study was carried out at SDM College of Medical Sciences, Dharwad, Karnataka, India for a period of 7 years...

Testicular germ cell tumours (TGCT) typically contain high numbers of infiltrating immune cells, yet the functional nature and consequences of interactions between GCNIS (germ cell neoplasia in situ) or seminoma cells and immune cells remain unknown. A co-culture model using the seminoma-derived TCam-2 cell line and peripheral blood mononuclear cells (PBMC, n = 7 healthy donors) was established to investigate how tumour and immune cells each contribute to the cytokine microenvironment associated with TGCT...

BACKGROUND: Although gastric adenoma is widely accepted as a precursor of gastric cancer, pre-existing adenoma is not always detected in gastric cancer patients. OBJECTIVE: To investigate the clinical characteristics of early gastric cancer (EGC) arising from adenoma, compared with those of EGC without pre-existing adenoma. METHODS: Patients who underwent endoscopic resection for EGC at a single tertiary hospital were divided into two groups based on the presence (ex-adenoma group) or absence (de novo group) of pre-existing adenoma on pathologic specimens...

Infantile myofibromatosis is a rare disorder of fibroblastic/myofibroblastic proliferation and represents the most frequent type of mesenchymal tumor in the neonatal period and primary infancy.Three clinical types have been described: solitary, multicentric, and generalized (with visceral involvement). A correct characterization of the histopathology is essential to diagnose these neoplasias in early infancy. We present a case of multicentric infantile myofibromatosis with regression over time.

PURPOSE: Detecting a recurrence after lung radiofrequency ablation (RFA) is based on a group of arguments that include CT, positron emission tomography (PET-CT) at 3 months and clinical patient follow-up. There is no one examination that is absolutely reliable. Recurrences are diagnosed tardily, when the cancers are locally extended, or when the patients are metastatic. The purpose of this article is to investigate the utility of dual-energy computed tomography (DECT) in order to assess therapeutic responses to RFA for lung neoplasia...

The aim of this study was to investigate the expression of minichromosome maintenance complex component 7 (MCM7) in gastric mucosal lesions, further to find its potential effect as a biomarker to distinguish intraepithelial neoplasia from gastric mucosal lesions. MCM7 and Ki67 were detected in 93 cases of gastric mucosal lesions by immunohistochemistry. MCM7 and Ki67 expression in GT were lowest compared with other groups (P<0.001), meanwhile there were significant differences compared with Group IM and other groups in MCM7 and Ki67 expression (P<0...

The natural development of cervical cancer, which takes many years, is mostly initiated by infection with human papillomavirus (HPV) and is characterized by the development of precancerous lesions, cervical intraepithelial neoplasia 3 (CIN3), which are defined as abnormal changes in epithelial cells that cover the cervix surface. Since the pre-cancerous process is microscopic and asymptomatic, early detection is based on cytological screening, the Pap test. In Israel, Pap tests are performed based on selfreferral for testing and not within the framework of a national screening program because of the low incidence rate of cervical cancer in Israel...

We try to explore the value of aberrant DNA methylation of several cancer-related genes in plasma as non-invasive biomarkers for gastric cancer (GC) and precancerous lesions. By using methylation-specific polymerase chain reaction assay we determined the methylation status of three selected genes ZIC1, HOXD10 and RUNX3 in blood samples from patients with GC and precancerous lesions. We discovered that the methylation rate of ZIC1, HOXD10 and RUNX3 increased significantly in the progression of gastric carcinogenesis...

Human papillomaviruses (HPV) are widespread DNA viruses that can infect epithelial cells of the skin and mucosa. Most HPV infections remain clinically unapparent and clear spontaneously. In few cases, however, HPV infections persist and can cause benign and malignant neoplasms at different anatomic locations. Malignant HPV-induced neoplasms are caused by distinct types of HPV (oncogenic or high-risk (HR) HPV types) and present in the anogenital (anus, penis, uterine cervix, vagina and vulva) and head and neck (particularly oropharynx) region...

Cri du Chat syndrome (CdC) is a chromosomal abnormality (deletion of short arm of chromosome 5) associated with intellectual disability and typical anatomical abnormalities. Research up to now focuses on the management of the disease during childhood. The longer lifespan of these patients warrants deeper investigations of how and if aging could be affected by the syndrome. We decided to focus on the association of the disease with proliferative disorders. Data on proliferative disorders in a cohort of 321 patients from Italian and German Cri du Chat databases were collected...

An update on the current epidemiology and a review of the risk factors of cervical and endometrial cancers are discussed. Cervical cancer prevention with a focus on human papillomavirus vaccination and cervical cancer screening is reviewed, emphasizing the new focus of less frequent intervention in an effort to maintain high rates of early detection of disease while decreasing unnecessary and anxiety-provoking colposcopies, biopsies, and excisional procedures. The replacement of traditional endometrial hyperplasia terminology with more relevant clinical categories, with an emphasis on the introduction of endometrial intraepithelial neoplasia, is presented...

Glyoxalase 2 (Glo2), a metabolic enzyme, is overexpressed in some human cancers which suggests this enzyme may play a role in human tumorigenesis. In prostate cancer (PCa) the role of Glo2 has been scarcely investigated and there are no studies addressing a causative involvement of this protein in this neoplasia. Here we examined the immunohistochemical profile of Glo2 in human PCa and benign adjacent tissues and investigated Glo2 involvement in PCa development in human prostate cell lines. PCa and matched adjacent normal tissues were obtained from paraffin sections of primary PCa from 20 patients who had undergone radical prostatectomy...

Pancreatic ductal adenocarcinoma is a highly malignant tumor with poor prognosis, and the biomarkers for the early diagnosis, targeting therapy, and prognosis are still not clinically available. This study investigated the expression of forkhead box P1 and forkhead box O3a proteins in human pancreatic ductal adenocarcinoma tumor tissues and pancreatic tissues with and without benign lesions using immunohistochemical staining. Results showed that the positive rates of forkhead box P1 and forkhead box O3a protein expression were significantly lower in pancreatic ductal adenocarcinoma tumors compared to peritumoral tissues, benign pancreatic tissues, and normal pancreatic tissues (p < 0...

Primary sclerosing cholangitis (PSC) is a disease of the biliary tract, which has been documented in the literature since 1867. This disease has a strong predilection for affecting men and can be seen in individuals as young as 2 years of age. PSC has a strong associated with inflammatory bowel disease, more commonly with ulcerative colitis, and is also part of the clinical spectrum of IgG4-related diseases. Small-duct PSC, a variant of PSC, also has an association with inflammatory bowel disease. The exact pathogenesis of PSC is not well understood at present, however, is likely a combination of a genetic predisposition with alteration of the molecular structure of the gut...

Pancreatic ductal adenocarcinoma (PDAC) remains a highly lethal disease in critical need of new therapeutic strategies. Here, we report that the stress-inducible 78-kDa glucose-regulated protein (GRP78/HSPA5), a key regulator of endoplasmic reticulum homeostasis and PI3K/AKT signaling, is overexpressed in the acini and PDAC of Pdx1-Cre;Kras(G12D/+);p53(f/+) (PKC) mice as early as 2 mo, suggesting that GRP78 could exert a protective effect on acinar cells under stress, as during PDAC development. The PKC pancreata bearing wild-type Grp78 showed detectable PDAC by 3 mo and rapid subsequent tumor growth...
