BACKGROUND Colorectal cancer (CRC) is the third frequent cancer in Korea. There are several risk factors including male sex, older age, smoking and family history of colon cancer. Recently, obesity is thought to be a risk factor for CRC and advanced colon polyps. Therefore, we designed a cross-sectional study to determine the association between BMI and advanced colorectal neoplasia. METHODS ...

PURPOSE We examined rebiopsies in MUSIC (Michigan Urological Surgery Improvement Collaborative) to understand adherence to guidelines recommending repeat prostate biopsy in patients with multifocal high grade prostatic intraepithelial neoplasia or atypical small acinar proliferation. MATERIALS AND METHODS We analyzed data on men undergoing repeat biopsy, practice patterns and cancer detection...

OBJECTIVES To determine the effect of human papillomavirus (HPV) quadrivalent vaccine on the risk of developing subsequent disease after an excisional procedure for cervical intraepithelial neoplasia or diagnosis of genital warts, vulvar intraepithelial neoplasia, or vaginal intraepithelial neoplasia. DESIGN Retrospective analysis of data from two international, double blind, placebo controll...

Endoscopic treatment of early esophageal neoplasia has widely been established in gastroenterology. It has been shown to be effective and safe also in the long-term follow-up, and it is – in contrast to the previous goldstandard, which is esophageal resection – organ preserving. There is no treatment-related mortality and a very low morbidity. In early Barrett’s neoplasia, the two-step concept ...

AIM To verify if patients with cervical neoplasia produce mediators that reduce leukocyte function. METHODS Control neutrophils incubated with normal serum or serum from pre-invasive or invasive neoplasia patients were assayed for chemotaxis. Mediators were assayed in serum and in leukocyte supernatants. Experiments were also performed in random patients after surgery. RESULTS Neutrophils i...

This past year, we have seen a phenomenal growth in the number of articles submitted to Neoplasia, breaking all previous records. While the number of submitted articles continues to rise on an annual basis, the editorial office continues to maintain a very high standard of scientific quality, which has been consistently maintained over the last 7 years. Since its inception back in 1999, Neoplas...

BACKGROUND Colonoscopic screening for colorectal cancer has been suggested because sigmoidoscopy misses nearly half of persons with advanced proximal neoplasia. OBJECTIVE To create a clinical index to stratify risk for advanced proximal neoplasia and to identify a subgroup with very low risk in which screening sigmoidoscopy alone might suffice. DESIGN Cross-sectional study. SETTING A comp...

BACKGROUND The pathogenesis for colorectal cancer remains unresolved. A growing body of evidence suggests a direct correlation between cyclooxygenase enzyme expression, prostaglandin E2 metabolism and neoplastic development. Thus further understanding of the regulation of epithelial functions by prostaglandin E2 is needed. We hypothesized that patients with colonic neoplasia have altered coloni...

BACKGROUND Primary sclerosing cholangitis (PSC) is 1 of the leading causes of liver transplantation (LTX) in Scandinavia, and an increasing number of PSC patients have been transplanted in Norway during the last 2 decades. This trend is partly attributable to the recently established practice in Norway of offering LTX to PSC patients with cholangiocellular dysplasia. Based on the controversy as...

OBJECTIVE To evaluate the cumulative incidence of cervical intraepithelial neoplasia II or worse (grade II+) or cervical intraepithelial neoplasia grade III+ after short term persistence of prevalently detected carcinogenic human papillomavirus (HPV). DESIGN Population based cohort study. SETTING Guanacaste, Costa Rica. PARTICIPANTS 2282 sexually active women actively followed after enrol...
