RESUMO
CONTEXT: Liver transplantation (LT) is considered the ideal therapy for patients with hepatocellular carcinoma (HCC) having cirrhosis but the shortage of liver donors and the risk of dropout from the wait list due to tumor progression severely limit transplantation. A new prognostic score, the HCC-model for end-stage liver disease (HCC-MELD), was developed by combining α-fetoprotein (AFP), MELD, and tumor size, to improve risk stratification of dropout in patients with HCC. OBJECTIVES: In this study, we investigated the ability of the HCC-MELD score in predicting the posttransplant for patients fulfilling Milan criteria (MC). DESIGN: Two hundred patients with stage II tumor were retrospectively reviewed from a total of 1290 transplants performed at our institution from October 1997 through April 2015. Cox regression analysis was performed to identify the prognostic factors impacting the posttransplant survival. RESULTS: Overall survival at 1, 5, and 10 years was 89.3%, 71.1%, and 67.2%, whereas disease-free survival was 86.4%, 66.5%, and 52.4%, respectively. Multivariate analysis showed HCC-MELD score (hazard ratio [HR] 39.6, P < .001) and microvascular invasion (HR 2.41, P = .002) to be independent risk factors for recurrence, whereas HCC diameter (HR 1.15, P = .041), HCC-MELD (HR 15.611, P = .006), and grading (HR 2.17, P = .03) proved to be predictive factors of poor overall survival. CONCLUSION: Our study showed the validity of the HCC-MELD equation in the evaluation of patients undergoing LT for HCC. This score offers a reliable method to assess the risk of waiting list dropout and predict posttransplantation outcomes.

BACKGROUND: Liver transplantation (LT) is considered the best treatment option for HCC patients with cirrhosis. However, the scarce availability of liver donors and the risk of dropout from the waiting list due to the tumor progression severely limit LT for HCC. In this study, we evaluate the survival and recurrence in a cohort of patients undergoing LT for HCC fulfilling "Milan Criteria" (MC) pre-LT. In this study, we propose the development of a new prognostic score which could improve the accuracy in predicting recurrence post-LT. METHODS: Between 1997 and 2011, out of 1010 LT performed in our unit, 131 patients had T2 staged HCC (inside MC). The prognostic model predicting HCC recurrence post-LT was derived from Cox regression analysis. The performance of this model was validated in an external cohort of 198 HCC patients transplanted at another center. RESULTS: Overall survival at 1-3-5 years was 87%, 74.4%, 68.2%, whereas recurrence-free survival was 94.1%, 81.4%, 77.6%, respectively. Predictive factors for recurrence-free survival included high tumor grading (HR 5.01; p = 0.006) and tumor diameter (HR 1.46; p = 0.045). According to this model, the estimated relative risk of HCC recurrence after LT is given by this formula: 0.382 × (Tumor size [cm]) + 1.613 × (if Grading 3-4). The ROC curve was 0.878 (p < 0.001) in predicting HCC recurrence. CONCLUSION: In conclusion, our study showed that the use of this new prognostic score, taking into account maximal tumor diameter and tumor differentiation, improves the accuracy of Milan criteria in predicting HCC recurrence.

We describe an unprecedented, disastrous complication after bilateral lung transplantation (BLT), a bilateral bronchial dehiscence with a right bronchoesophageal fistula leading to life-threatening septic shock. We also report the successful endoscopic management of this complication by double stenting and stress the efficacy of the multidisciplinary approach to this critical case.

To reduce the time needed for clamping or circulatory arrest (or both) during substitution of a prosthesis for the thoracic aorta, we developed an expandable device that can be used with any commercially available prosthetic graft to enable sutureless aortic anastomosis. Improvements upon a previous version of the device include the use of nickel-titanium alloy (Nitinol) instead of stainless steel. This, together with an improved wire-looping design, now enables continuous control of diameter, even when the device is in contact with blood. A further improvement consists of 4 metallic hooks on the outer surface, which enable firm fixation to the aortic stump. In March 2001, a 47-year-old man was admitted to our institution for evaluation of left upper-lobe bronchogenic adenocarcinoma that had infiltrated the distal aortic arch and upper descending aorta. Re-staging of the neoplasm ruled out distant metastasis. We resected the infiltrated aortic wall en bloc with the upper lobe. The expandable device enabled the distal anastomosis of the aortic prosthesis to be performed easily, in less than 3 minutes. The main advantages of this device are an easier, quicker anastomosis and the absolute prevention of suture-line hemorrhage (no suture line). The expandable device overcomes the drawbacks of the intraluminal ringed prosthesis used in the past.
