Abstract Background: Despite recent advances in colorectal cancer (CRC) diagnosis and population screening programs, the identification of patients with preneoplastic lesions or with early CRC stages remains challenging and is important for reducing CRC incidence and increasing patient’s survival. Methods: We analysed 76 colorectal tissue samples originated from early CRC stages, normal or inflamed mucosa by label-free proteomics. The characterisation of three selected biomarker candidates was performed by immunohisto‑ chemistry on an independent set of precancerous and cancerous lesions harbouring increasing CRC stages. Results: Out of 5258 proteins identified, we obtained 561 proteins with a significant differential distribution among groups of patients and controls. KNG1, OLFM4 and Sec24C distributions were validated in tissues and showed differ‑ ent expression levels especially in the two early CRC stages compared to normal and preneoplastic tissues. Conclusion: We highlighted three proteins that require further investigations to better characterise their role in early CRC carcinogenesis and their potential as early CRC markers. [less ▲]

INTRODUCTION: Sessile serrated adenoma/polyp (SSA/p) is a precancerous lesion, mostly located in the right side of the colon (cecum, ascending and transverse colon). The difficulty is to visualize this lesion during colonoscopy because of its subtle appearance. MATERIAL AND METHOD: We compared proteomes of serrated polyps (SSA/p) and conventional adenomas using residual human formalin fixed paraffin embedded (FFPE) samples. FFPE-FASP method was applied on samples before label free proteomic analysis. Immunohistochemistry (IHC) characterisation of one candidate marker was performed for tissue validation on an independent set of samples including: conventional adenomas (low and high-grade dysplasia), serrated polyps (hyperplastic polyps, SSA/p and traditional serrated adenoma) and finally normal colon (taken at the margin of colorectal cancer (CRC) or of diverticular disease). RESULTS: Proteomics provided 765 proteins (out of 5992 proteins identified) significantly discriminating conventional adenomas from serrated lesions. We selected 53BP1 (Tumor suppressor p53-binding protein 1) among these for IHC validation, because of its tumor suppressor gene function and role as a mediator of DNA damage checkpoint. 53BP1 appeared significantly up-regulated in proteomes of low and high grade adenomas compared to these of normal tissue and SSA/p. 53BP1 IHC signal was located in the nucleus and the percentage of positive nucleus decreased in serrated polyps, especially in crypts and in the border epithelium, confirming part of the proteomic results. CONCLUSION: This study highlights potential marker proteins, including 53BP1 from which IHC signal was strongly decreased in some serrated polyps. The loss of 53BP1 has been associated with tumour progression and poor prognosis, while little is currently known about its involvement in precancerous CRC lesions. 53BP1 decrease of expression in the nucleus and therefore possible loss of function in some epithelial cells could reflect important changes occurring during dysplasia to neoplasia progression in serrated lesions.

Abstract The association of primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) is known as an overlap syndrome (OS). OS can also be described in the setting of concomitant presence of AIH and PSC. These diseases can in some cases be associated with ulcerative colitis. In this case report we describe, to our knowledge, the first case in the literature of a young Caucasian male suffering from ulcerative colitis and an overlap syndrome consisting of an association between PSC-AIH, with the concomitant presence of a membranous glomerulonephritis.

Dans les années à venir, nous serons de plus en plus amenés à prendre en charge des patients âgés en oncologie. Dans ce contexte, quelles sont les évidences scientifiques à notre disposition qui nous permettent de prendre en charge de façon correcte cette population oncologique âgée ? Les patients âgés présentent souvent de multiples co-morbidités pouvant interférer avec le traitement oncologique rendant d’autant plus complexe leur prise en charge. Le pic d’inci - dence du cancer du rectum se situe autour des 80 ans, loin au-dessus de l’âge moyen des patients inclus dans les études cliniques. La survie globale des patients traités pour un cancer du rectum s’est améliorée au cours de la dernière décennie, essentiellement pour des patients de moins de 75 ans. Le trai - tement du cancer du rectum nécessite une approche multidis - ciplinaire. L’évaluation gériatrique en fait partie intégrante. Elle permet de définir au mieux la stratégie thérapeutique en fonction de l’état général du patient, de son contexte neuro- psychologique, fonctionnel et social. La radiothérapie joue un rôle majeur dans le traitement du rectum. Quelle est sa place chez les personnes âgées ? Bénéficient-elles également de la radiothérapie, comme la population jeune sélectionnée dans les études contrôlées ? Quel est l’impact de ce traitement sur la qualité de vie ? Voilà des questions essentielles auxquelles nous allons tenter d’apporter une réponse [less ▲]

Depuis plusieurs décades, la radiothérapie préopéra - toire ou postopératoire joue un rôle important dans le contrôle local de l’adénocarcinome du rectum. Cette dernière décennie, avec la systématisation de la chirurgie d’exérèse en totalité du mésorectum (TME), le profil de récidive locale du cancer du rectum a été fortement modifié. Dans un tel contexte, la place de la radiothérapie doit être réévaluée en tenant compte de ces modifications. Dans cet article, nous proposons de faire la revue des différentes grandes études concernant les techniques et les indications d’un traitement de radiothérapie pré- ou post opératoire dans le contexte d’une chirurgie rectale TME.

Introduction: Donation after circulatory death (DCD) donors have been proposed to partially overcome the organ donor shortage. DCD-LT remains controversial, with reported increased risk of ischemic cholangiopathy leading to graft loss. The authors retrospectively reviewed a single centre experience with DCD-LT in a 9-year period. Patients and Methods: 70 DCD-LT were performed from 2003 to November 2012. All DCD procedures were performed in operative rooms. Median donor age was 59 years. Most grafts were flushed with HTK solution. Allocation was centre-based. Median total DCD warm ischemia was 19.5 min. Mean follow-up was 36 months. No patient was lost to follow-up. Results: Median MELD score at LT was 15. Median cold ischemia was 235 min. Median peak AST was 1,162 U/L. Median peak bilirubin was 31.2 mg/dL. Patient and graft survivals were 92.8% and 91.3% at one year and 79% and 77.7% at 3 years, respectively. One graft was lost due to hepatic artery thrombosis. No PNF or graft loss due to ischemic cholangiopathy was observed in this series. Causes of death were malignancies in 8 cases. Discussion: In this series, DCD LT appears to provide results equal to classical LT. Short cold ischemia and recipient selection with low MELD score may be the keys to good results in DCD LT, in terms of graft survival and avoidance of ischemic cholangiopathy. [less ▲]

After fifteen years of use, the anti-TNF antibodies have become the corner stone of the treatment of moderate and severe Crohn's disease. The skill acquired over the years through experimental trials and clinical experience leads to increased therapeutic efficacy and minimized risks. These antibodies are introduced increasingly earlier in Crohn's disease as well as in a broader range of patients, aiming at changing the natural history of the diseases by avoiding the development of intestinal tissue damage and complications.

Introduction. This study investigated changes in kidney function over time among a cohort of patients undergoing pancreas transplantation alone (PTA) from January 2002 to December 2011. Patients and Methods. Ten of eighteen PTA patients bearing functioning grafts for at least 1 year were recruited for the analysis. Primary endpoints were changes in mean serum creatinine (SCr, mg/L) and mean estimated glomerular filtration rate (eGFR) using the 4-variable Levey-MDRD equation (mL/min/1.73 m2) comparing baseline (pretransplantation) to 6-month, 1-year, 3-year, and 5-year posttransplantation values. Mean follow-up time was 75.7 20.5 months (range, 46–106.5). Results. Baseline eGFR was 89.3 27.9 (range, 58–145). eGFR decreased to 75.7 26.2, 71 20.6, 66.5 14.8, and 62.1 11.2 at 6 months, 1, 3, and 5 years representing 15.2%, 20.5%, 15.8%, and 22.6% percentage decreases respectively (P .05 for all pairwise comparisons). The Baseline SCr was 8.6 2.3 mg/L (range, 5–13). SCr progressively increased to 10.1 3, 10.5 3.1, 10.9 3.1, and 11.3 1.7 at 6 months, 1, 3, and 5 years a 17.1%, 22%, 16.6%, and 19.9% increase respectively (P .05 for all pairwise comparisons). One of ten, 2/8, and 3/7 patients displayed an eGFR 60 at transplantation versus 3 and 5 years thereafter, respectively. No patient developed a SCr 25 mg/L or eGFR 30 or needed dialysis or kidney transplantation. Five of ten patients had micro-albuminuria or proteinuria before transplantation. Tacrolimus levels were within recommended therapeutic ranges over time. Conclusion. Kidney function deteriorated significantly after PTA. Understanding of risk factors for the development of renal impairment is important to preserve kidney function and to select appropriate candidates for PTA. [less ▲]
