Early liver transplantation can improve survival in patients with a first episode of severe alcoholic hepatitis not responding to medical therapy. (Funded by Société Nationale Française de Gastroentérologie.).

Early identification of patients with severe (discriminant function > 32) alcoholic hepatitis (AH) not responding to corticosteroids is crucial. We generated a specific prognostic model (Lille model) to identify candidates early on for alternative therapies. Three hundred twenty patients with AH prospectively treated by corticosteroids were included in the development cohort and 118 in its validation. Baseline data and a change in bilirubin at day 7 were tested. The model was generated by logistic regression. The model combining six reproducible variables (age, renal insufficiency, albumin, prothrombin time, bilirubin, and evolution of bilirubin at day 7) was highly predictive of death at 6 months (P < 0.000001). The area under the receiver operating characteristic (AUROC) curve of the Lille model was 0.89 ؎ 0.02, higher than the Child-Pugh (0.62 ؎ 0.04, P < 0.00001) or Maddrey scores (0.66 ؎ 0.04, P < 0.00001). In the validation cohort, its AUROC was 0.85 ؎ 0.04, still higher than the other models, including MELD (0.72 ؎ 0.05, P ‫؍‬ 0.01) and Glasgow scores (0.67 ؎ 0.05, P ‫؍‬ 0.0008). Patients above the ideal cutoff of 0.45 showed a marked decrease in 6-month survival as compared with others: 25% ؎ 3.8% versus 85% ؎ 2.5%, P < 0.0001. This cutoff was able to identify approximately 75% of the observed deaths. Conclusion: In the largest cohort to date of patients with severe AH, we demonstrate that the term "nonresponder" can now be extended to patients with a Lille score above 0.45, which corresponds to 40% of cases. Early identification of subjects with substantial risk of death according to the Lille model will improve management of patients suffering from severe AH and will aid in the design of future studies for alternative therapies. (HEPATOLOGY 2007;45:1348-1354 T he treatment of severe forms of alcoholic hepatitis (AH) constitutes a major challenge in management of severe alcoholic liver disease. Before the era of the Maddrey function (DF), 1,2 clinicians faced substantial difficulties in identifying subgroups of patients with high risk of death over a short term; as a consequence, survival of untreated patients enrolled in randomized controlled trials (RCTs) ranged from 0 to 81%. 3 Since the use of DF (DF Ն 32) in several RCTs, 1,4-6 spontaneous 2-month survival has been approximately 50%. The DF clearly demonstrates the tremendous progress provided by elaborating specific prognostic functions for AH. The advantage of accurate models has been confirmed by the growing importance of the MELD score in the selection of candidates for liver transplantation. [7][8][9] In patients with DF Ն 32, several RCTs and a recent meta-analysis showed that corticosteroids improve shortterm survival. 1,5,10-14 However, novel strategies or molecules are required, in light of the fact that approximately 40% of patients die at 6 months. 15 Therefore, improvement in the prediction of mortality in severe AH is warranted. However, we lack evidence supporting the higher efficacy of new models such as MELD and Glasgow scores compa...

Purpose Metastasis and drug resistance are the major limitations in the survival and management of cancer patients. This study aimed to identify the mechanisms underlying HT29 colon cancer cell chemoresistance acquired after sequential exposure to 5-fluorouracil (5FU), a classical anticancer drug for treatment of epithelial solid tumors. We examined its clinical relevance in a cohort of colon cancer patients with liver metastases after 5FU-based neoadjuvant chemotherapy and surgery. Results We show that a clonal 5F31 cell population, resistant to 1μM 5FU, express a typical cancer stem cell-like phenotype and enter into a reversible quiescent G0-state upon re-exposure to higher 5FU concentrations. These quiescent cells overexpressed the tyrosine kinase c-Yes that became activated and membrane-associated upon 5FU exposure. This enhanced signaling pathway induced the dissociation of the Yes/YAP (Yes-associated protein) molecular complex and depleted nuclear YAP levels. Consistently, c-Yes silencing decreased nuclear YAP accumulation and induced cellular quiescence in 5F31 cells cultured in 5FU-free medium. Importantly, c-Yes and YAP transcript levels were higher in liver metastases of colon cancer patients after 5FU-based neoadjuvant chemotherapy. Moreover, the c-Yes and YAP levels positively correlated with colon cancer relapse and shorter patient survival (p<0.05 and p<0.025, respectively). Conclusions We identified c-Yes and YAP as potential molecular targets to eradicate quiescent cancer cells and dormant micrometastases during 5FU chemotherapy and resistance and as predictive survival markers for colon cancer.
