CONTEXT: Although the majority of sellar lesions are related to pituitary adenomas, the region gives rise to a variety of neoplasms that can be associated with substantial morbidity and/or mortality. EVIDENCE ACQUISITION: Information from reviews and guidelines of relevant societies dealing with such neoplasms, and articles that have provided new developments which made important contributions in their pathogenesis and treatment up to 2018, were obtained: public indexes such as PubMed/MEDLINE were used with the search items...

While organized screening for colorectal cancer has been extended to the whole of France since 2008, there is no evidence to suggest that this screening based on use of the guaiac test had a significant impact on trends in its incidence and mortality in France in the last 10 years. Following the first prospective trials conducted in Normandy, FIT (Fecal Immunological Test) was proposed to the entire national territory from 2015. Three years after its generalization, it is of course impossible to measure the effects of this modification of strategy on the incidence or mortality from colorectal cancer...

Colorectal cancer screening with colonoscopy is commonly used in candidate patients for liver transplantation. We initiated this study to define the risk-benefit ratio of performing screening colonoscopy in this population. A retrospective observational study of all consecutive patients undergoing colonoscopy during pre-liver transplantation screening between 2004-2017 was conducted. Endoscopic and pathological findings and clinical events potentially related to the colonoscopy in the 30 days after the procedure were registered and compared with a 30 days in-patient control time frame...

Background/aim: Prolonged hypercalcemia impairs renal function, and a reduced glomerular filtration rate (GFR) is typical in advanced primary hyperparathyroidism (PHPT). There are scarce data related to predictors of renal impairment in patients with PHPT. Hence, we aimed to evaluate changes in kidney function in PHPT patients after parathyroidectomy (PTX) and identify factors associated with GFR variation in these patients. Materials and methods: One hundred and twenty-five patients with PHPT who underwent surgery between 2012 and 2014 were enrolled in the study...

Lung cancer is the leading cause of cancer-related death. Two-thirds of cases are diagnosed at an advanced stage that is refractory to curative treatment. Therefore, strategies for the early detection of lung cancer are urgently sought. Total circulating free DNA (cfDNA) and tumour-derived circulating tumour DNA (ctDNA) are emerging as important biomarkers within a 'liquid biopsy' for monitoring human disease progression and response to therapy. Owing to the late clinical diagnosis of lung adenocarcinoma, the potential for cfDNA and ctDNA as early detection biomarkers remains unexplored...

Background Kallikrein-related peptidases (KLKs) are a subgroup of serine proteases located on chromosome 19q13.3. Most KLKs have been extensively studied as potential biomarkers for several carcinomas and other diseases. KLK5 was originally identified from a keratinocyte library, and its enzyme was purified from the stratum corneum of human skin. KLK5 was shown to be differentially expressed in a variety of endocrine tumors, although it is not as yet examined widely in colorectal cancer (CRC). Methods In this study, we quantitatively assessed the mRNA expression status of KLK5 in 197 colorectal tissues from 133 patients (70 cancerous and their paired normal colonic mucosa for 64 of them, as well as 63 colorectal adenomas) by quantitative real-time PCR (qPCR) using TaqMan probes...

OBJECTIVE: Sessile serrated adenomas/polyps (SSA/Ps) are now recognized as potential cancer precursors, but little is known about their natural history. We assessed the in vivo growth rates of histologically proven SSA/Ps at longitudinal CT colonography (CTC) and compared results with non-advanced tubular adenomas (TAs). METHODS: We identified a cohort of 53 patients (mean age, 54.8 ± 5.5 years; M:F, 26:27) from one center with a total of 58 SSA/Ps followed longitudinally at CTC (mean follow-up interval, 5...

BACKGROUND Before partial adrenalectomy for primary aldosteronism due to a primary adrenal adenoma, the aldosterone-producing tumor can be localized by segmental adrenal vein sampling (S-AVS). Cardiologists, who regularly perform percutaneous coronary intervention (PCI), or coronary angioplasty with stent, may not be familiar with the technique of S-AVS. A case of the use of S-AVS is reported in a patient who presented with primary aldosteronism and a right adrenal adenoma. CASE REPORT A 44-year-old man with a history of hypertension presented with a man in the posterior part of the right adrenal gland...

Intraluminal pathologic conditions of the bile ducts and gallbladder are common, most frequently consisting of calculi and adenocarcinoma. In recent years, intraductal papillary neoplasm of the bile ducts (IPN-B), which is analogous to intraductal papillary mucinous neoplasm of the pancreas, has been recognized as a distinct pathologic entity and a precursor lesion to adenocarcinoma of the bile ducts. Intraductal tubulopapillary neoplasm (ITPN) of the bile duct was subsequently described as a distinct pathologic entity...

Background: Craniotomy and transphenoidal microsurgery are surgical options for treatment of pituitary adenoma at Korle Bu Teaching Hospital(KBTH). Despite major advances and reported success rates of transphenoidal resection globally, paucity of local data regarding visual outcome of either procedure exists. We evaluated the visual outcome of patient with pituitary adenoma following surgery in a tertiary hospital in Ghana. Methods: This is a prospective study of 18 of 45 consecutive new patients with pituitary adenoma seen from November 2010 to July 2013 at Korle-Bu Teaching Hospital(KBTH), Accra, Ghana...

BACKGROUND: Colonoscopy is considered a valid primary screening tool for colorectal cancer (CRC). The decreasing risk of CRC observed in patients undergoing colonoscopy is correlated with the adenoma detection rate (ADR). Due to the fact that screening programs usually start from the age of 50, very few data are available on the risk of adenoma between 40 and 49 years. However, the incidence of CRC is increasing in young populations and it is not uncommon in routine practice to detect adenomas or even advanced neoplasia during colonoscopy in patients under 50 years...

BACKGROUND & AIMS: The fecal immunochemical test (FIT) is the tool most frequently used for colorectal cancer (CRC) screening worldwide. It is unclear how the use of aspirin and oral anticoagulants in the screening population affect the diagnostic performance of FIT. METHODS: We performed a cross-sectional study in an ongoing CRC screening trial in Norway. Participants 50-74 years old with a positive result from a FIT (>15μg hemoglobin/g feces) and subsequent colonoscopy (reference standard) were included...
