http://www.D-MELD.com, the Italian survival calculator to optimize donor to recipient matching and to identify the unsustainable matches in liver transplantation.

Optimization of donor-recipient match is one of the exciting challenges in liver transplantation. Using algorithms obtained by the Italian D-MELD study (5256 liver transplants, 21 Centers, 2002-2009 period), a web-based survival calculator was developed. The calculator is available online at the URL http://www.D-MELD.com. The access is free. Registration and authentication are required. The website was developed using PHP scripting language on HTML platform and it is hosted by the web provider Aruba.it. For a given donor (expressed by donor age) and for three potential recipients (expressed by values of bilirubin, creatinine, INR, and by recipient age, HCV, HBV, portal thrombosis, re-transplant status), the website calculates the patient survival at 90days, 1year, 3years, and allows the identification of possible unsustainable matches (i.e. donor-recipient matches with predicted patient survival less than 50% at 5 years). This innovative approach allows the selection of the best recipient for each referred donor, avoiding the allocation of a high-risk graft to a high-risk recipient. The use of the D-MELD.com website can help transplant surgeons, hepatologists, and transplant coordinators in everyday practice of matching donors and recipients, by selecting the more appropriate recipient among various candidates with different prognostic factors.

Neo-adjuvant chemo(radio)therapy in gastric cancer: Current status and future perspectives.

In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence. Remaining concerns pertain to the choice of the optimal therapy regimen, strict patient selection by accurate pre-operative staging, standardization of surgical procedures, and valid criteria for response evaluation. New well-designed trials will be necessary to find the best therapeutic approach in pre-operative settings and the best way to combine old-generation chemotherapeutic drugs with new-generation molecules.
