    La pathologie digestive haute est riche et variĂ©e. Les signes fonctionnels digestifs constituent les motifs frĂ©quents de consultation tant en mĂ©decine gĂ©nĂ©rale qu’en gastro-entĂ©rologie. L’endoscopie constitue l’examen de rĂ©fĂ©rence pour le diagnostic et dans certains cas pour le traitement des pathologies digestives. Nous voulons dĂ©terminer les anomalies rencontrĂ©es en fibroscopie haute Ă  Bangui. MĂ©thodologie : Il s’agissait d’une Ă©tude transversale d’une durĂ©e de deux ans incluant les patients des deux sexes ayant rĂ©alisĂ© l’endoscopie digestive haute (EDH) dont le compte rendu Ă©tait complet. RĂ©sultats : Au total 1233 anomalies ƓsogastroduodĂ©nales ont Ă©tĂ© observĂ©es. Les anomalies les plus frĂ©quentes Ă©taient l’incontinence cardiale (467 cas soit 37,88%) et les anomalies inflammatoires (443 cas soit 35,93%). Six cas de cancer (0,61%) Ă©taient observĂ©s au niveau gastrique. Les lĂ©sions Ă©taient observĂ©es dans l’estomac dans 980 cas (79,48%), Ɠsophage dans 196 cas (15,9%). Les lĂ©sions duodĂ©nales Ă©taient observĂ©es dans 57 cas (4,62%). Les anomalies gastriques Ă©taient dominĂ©es par les gastrites dans 417 cas (42,55%) alors que les lĂ©sions Ɠsophagiennes et duodĂ©nales Ă©taient dominĂ©es respectivement par les varices Ɠsophagiennes dans 139 cas (70,92%) et les ulcĂšres dans 55 cas (96,49%).

Six cases of cancer (0.61%) were observed at the gastric level. The lesions were observed in the stomach in 980 cases (79.48%), esophagus in 196 cases (15.9%). Duodenal lesions were observed in 57 cases (4.62%). Gastric abnormalities were dominated by gastritis in 417 cases (42.55%) while esophageal and duodenal lesions were respectively dominated by esophageal varices in 139 cases (70.92%) and ulcers in 55 cases (96.49%). %).

    Global variation in the long-term outcomes of ypT0 rectal cancers

    Background Colorectal cancer mortality presents world-wide variation. In rectal cancers presenting a complete/nearly-complete tumor response (ypT0/ypTis) following neoadjuvant treatment, the features correlated to nodal metastases and relapses still need to be defined. Methods An international cohort study enrolling ypT0/ypTis rectal cancers surgically treated from 2012 to 2017 was conducted. A propensity matching was used to balance nodal-positive and nodal-negative patients and statistical analyses were performed to investigate survivals, using a bootstrap model for internal validation. The features correlated with nodal metastasis were studied. Countries with participating centers were ranked using the World Bank (WBI), Human Development (HDI) and Global Gender Gap (GGG) indexes to compare survivals. Results 680 ypT0/ypTis from 52 European, Australian, Indian and American Institutions were analyzed. Mean follow-up was of 30.4 months. 96.5% were treated with total mesorectal excision, 7.2% were nodal-positive and 8.8% relapsed. Distal cancers (HR 0.71 95%CI: 0.56-0.91) and nodal metastasis and nodal metastasis (HR 3.85 95%CI:1.12–13.19) correlated with worse DFS, whereas a younger age was of borderline significance (HR 0.95 95%CI:0.91–0.99). The bootstrap analysis validated the model on 5000 repetitions. A short-course radiotherapy (OR 0.18 95%CI:0.09–0.37) correlated with the occurrence of nodal metastasis. Those countries classified in the low/medium-WBI, medium-HDI and lower-GGG ranks documented worse DFS curves (respectively p < 0.0001, p < 0.0001 and p 0.0002). However, the clinical stages were similar and patients from medium-HDI countries received more adjuvant chemotherapy than the others (p < 0.0001). Conclusion Sub-groups at risk for relapses and nodal metastasis were identified. A global variation exists also when benchmarking a rectal cancer complete regression

    Furin Prodomain ppFurin Enhances Ca2+ Entry Through Orai and TRPC6 Channels’ Activation in Breast Cancer Cells

    The intracellular calcium concentration ([Ca2+]i) modulation plays a key role in the regulation of cellular growth and survival in normal cells and failure of [Ca2+]i homeostasis is involved in tumor initiation and progression. Here we showed that inhibition of Furin by its naturally occurring inhibitor the prodomain ppFurin in the MDA-MB-231 breast cancer cells resulted in enhanced store-operated calcium entry (SOCE) and reduced the cell malignant phenotype. Expression of ppFurin in a stable manner in MDA-MB-231 and the melanoma MDA-MB-435 cell lines inhibits Furin activity as assessed by in vitro digestion assays. Accordingly, cell transfection experiments revealed that the ppFurin-expressing cells are unable to adequately process the proprotein convertase (PC) substrates vascular endothelial growth factor C (proVEGF-C) and insulin-like growth factor-1 receptor (proIGF-1R). Compared to MDA-MB-435 cells, expression of ppFurin in MDA-MB-231 and BT20 cells significantly enhanced SOCE and induced constitutive Ca2+ entry. The enhanced SOCE is impaired by inhibition of Orai channels while the constitutive Ca2+ entry is attenuated by silencing or inhibition of TRPC6 or inhibition of Orai channels. Analysis of TRPC6 activation revealed its upregulated tyrosine phosphorylation in ppFurin-expressing MDA-MB-231 cells. In addition, while ppFurin had no effect on MDA-MB-435 cell viability, in MDA-MB-231 cells ppFurin expression reduced their viability and ability to migrate and enhanced their sensitization to the apoptosis inducer hydrogen peroxide and similar results were observed in BT20 cells. These findings suggest that Furin inhibition by ppFurin may be a useful strategy to interfere with Ca2+ mobilization, leading to breast cancer cells’ malignant phenotype repression and reduction of their resistance to treatments.This research was funded by SIRIC-Brio, La Ligue Contre le Cancer and Region Nouvelle Aquitaine to A.M.K. and by PID2019-104084GB-C21 and PID2019-104084GB-C22/AEI/10.13039/501100011033, MICINN (Grant BFU2016-74932-C2) and Junta de Extremadura-Fondo Europeo de Desarrollo Regional (FEDER; Grants IB16046 and GR18061) to J.A.R. and T.S.

    <p>Abstract</p> <p>Background</p> <p>Clinical efficacy of chemotherapy in colorectal cancer is subjected to broad inter-individual variations leading to the inability to predict outcome and toxicity. The topoisomerase I inhibitor irinotecan (CPT-11) is worldwide approved for the treatment of metastatic colorectal cancer and undergoes extensive peripheral and tumoral metabolism. PXR is a xenoreceptor activated by many drugs and environmental compounds regulating the expression of drug metabolism and transport genes in detoxification organs such as liver and gastrointestinal tract. Considering the metabolic pathway of irinotecan and the tissue distribution of Pregnane × Receptor (PXR), we hypothesized that PXR could play a key role in colon cancer cell response to irinotecan.</p> <p>Results</p> <p>PXR mRNA expression was quantified by RT-quantitative PCR in a panel of 14 colon tumor samples and their matched normal tissues. PXR expression was modulated in human colorectal cancer cells LS174T, SW480 and SW620 by transfection and siRNA strategies. Cellular response to irinotecan and its active metabolic SN38 was assessed by cell viability assays, HPLC metabolic profiles and mRNA quantification of PXR target genes. We showed that PXR was strongly expressed in colon tumor samples and displayed a great variability of expression. Expression of hPXR in human colorectal cancer cells led to a marked chemoresistance to the active metabolite SN38 correlated with PXR expression level. Metabolic profiles of SN38 showed a strong enhancement of SN38 glucuronidation to the inactive SN38G metabolite in PXR-expressing cells, correlated with an increase of UDPglucuronosyl transferases UGT1A1, UGT1A9 and UGT1A10 mRNAs. Inhibition of PXR expression by lentivirus-mediated shRNA, led to SN38 chemoresistance reversion concomitantly to a decrease of UGT1A1 expression and SN38 glucuronidation. Similarly, PXR mRNA expression levels correlated to UGT1A subfamily expression in human colon tumor biopsies.</p> <p>Conclusion</p> <p>Our results demonstrate that tumoral metabolism of SN38 is affected by PXR and point to potential therapeutic significance of PXR quantification in the prediction of irinotecan response. Furthermore, our observations are pharmacologically relevant since many patients suffering from cancer diseases are often exposed to co-medications, food additives or herbal supplements able to activate PXR. A substantial part of the variability observed among patients might be caused by such interactions</p
