Clinical trials

Incisional hernia is a common complication after midline laparotomy and may significantly impact quality of life, morbidity, and healthcare costs. Patients undergoing cytoreductive surgery for ovarian cancer are considered at increased risk due to extensive surgical procedures, nutritional status, and exposure to systemic treatments. This prospective randomized clinical trial aims to evaluate whether prophylactic mesh placement during abdominal wall closure reduces the incidence of incisional hernia compared with conventional fascial closure in women undergoing cytoreductive surgery for ovarian cancer through a midline laparotomy. To control for the potential effect of negative pressure wound therapy (NPWT) on surgical site infection, participants will also be randomized to receive NPWT or standard wound dressing, resulting in four treatment arms.

The patients with non-resectable colorectal liver metastases (CRLM) have always being considered a particular subgroup of CRLM in which the therapeutic approach, is focused on strategies that allow a potential surgery like neoadjuvant systemic treatments. But, the underlying biology that causes this particular profile of spread in a proportion of patients that always recur and progress in the liver has not been properly characterized from a biological point of view. Unfortunately, these patients finally develop liver metastasis not amenable for local treatments and become refractory to systemic treatments even without developing extrahepatic liver metastases. As a result, liver transplantation (LT) is a potential for patients without extrahepatic involvement and nonresectable CRLM. There are several studies that aims to evaluate if LT increases overall survival compared to best alternative care. To our knowledge, none of these studies incorporate objectives focused on the underlying tumor biology of this particular population and the development of focused strategies including a dynamic disease monitoring and targeted treatments for this particular population.The METLIVER trial will permit to expand the genetic studies to the whole complexity of metastatic lesions and a more precise evaluation of their genetic heterogeneity. Moreover, it will help to precise the type of genetic analyses on liquid biopsies that can be designed for patients that will unfortunately relapse mostly with lung metastases after LT. Our proposal will maximize the opportunity to produce an unprecedented knowledge on CRLM evolution and will provide new opportunities for relapsed patients.

A prospective multicentre study which includes patients ≤ 70 years-old diagnosed of unresectable perihilar cholangiocarcinoma (pCCA) ≤3cm in radial diameter, without evidence of lymph node or distant metastases. Liver transplantation preceded by neoadjuvant radiochemotherapy will be performed in this selected group. The primary endpoint will be overall survival at 1, 3, and 5 years post-transplant. The secondary endpoints will be: 1) recurrence-free survival at 1, 3 and 5 years post-transplant; 2) intention-to-treat survival of all patients included in the study at 1,3 and 5 years; 3) the rate of patients included in the study who are finally transplanted.
