ABSTRACT
AIM: Sarcopenia is associated with poor prognosis in adult oncologic patients, with little evidence of this association in pediatric population, including hepatoblastoma. METHODS: Retrospective study in patients with hepatoblastoma, divided into those with or without sarcopenia. Sarcopenia was assessed by measuring psoas muscle area (PMA) at L4-L5 level on the CT/MR and defined as z-score values ≤ 2. Relapse and mortality were analyzed. RESULTS: Twenty-one patients (57.1% male) were included, with median age 35.7 months (IQR: 23.5-58.5). Seven (33.3%) had sarcopenia on initial studies compared to 14 (66.7%) who did not. No differences were found between groups in age, weight, PRETEXT, surgical treatment or. α-fetoprotein levels. Sarcopenia was associated with a higher rate of metastases at diagnosis (49.2% vs 0.0%; p = 0.026) and surgical complications (57.1% vs 21.4%, p = 0.047). After a median follow-up of 65.1 months (1.7-144.8), 2 patients (28.6%) had tumor relapse in sarcopenic group compared to 1 (7.1%) in non-sarcopenic group. Two patients died in sarcopenic group and 1 in non-sarcopenic group. Median event-free survival (EFS) was lower in sarcopenic group (100.38 ± 25.63 vs 118.91 ± 11.52 months) as well as overall survival (OS) (101.72 ± 24.86 vs 121.78 ± 8.75 months) with no statistical significance. Five-year EFS was also lower in sarcopenic group (71% vs 93%) as well as 5-year OS (71% vs 87%). CONCLUSIONS: Sarcopenia at diagnosis was associated with a higher rate of metastases and surgical complications in hepatoblastoma. Our data shows the first evidence of its role as a possible poor prognostic factor, influencing survival and risk of relapse. LEVEL OF EVIDENCE: II. TYPE OF STUDY: Original article. Retrospective study.
ABSTRACT
The current shortage of pediatric multivisceral donors accounts for the long time and mortality on the waiting list of pediatric patients. The use of donors after cardiac death, especially after the outbreak of normothermic regional perfusion, has increased in recent years for all solid organs except the intestine, mainly because of its higher susceptibility to ischemia-reperfusion injury. We present the first literature case of multivisceral donors after cardiac death transplantation in a 13-month-old recipient from a 2.5-month-old donor. Once exitus was certified, an extracorporeal membrane oxygenation circuit was established, cannulating the aorta and infrarenal vena cava, while the supra-aortic branches were clamped. The abdominal organs completely recovered from ischemia through normothermic regional perfusion (extracorporeal membrane oxygenation initially and beating heart later). After perfusion with the preservation solution, the multivisceral graft was uneventfully implanted. Two months later, the patient was discharged without any complications. This case demonstrates the possibility of reducing the time spent on the waiting list for these patients.
