- Abstract
Objective: The object of this study was to analyse our results with liver transplantation (LTX) for primitive malignant unresectable liver tumours in children and to discuss the controversial indications, based on our experience., Methods/patients: We report on 12 patients, aged 6 months to 14 years, with hepatic malignant tumours: 11 with hepatoblastoma and 1 with fibrolamellar hepatocelullar carcinoma without cirrhosis. LTX was the primary treatment in 10 patients (PRETEXT IV or any grade, if there was extension to the retrohepatic vena cava, 3 hepatic veins or portal vein) and a rescue therapy after recurrence for 1 and for persistence of unresectable macroscopic residuals in 2 patients. One of the patients who underwent a LTX as primary therapy had lung metastases previously resolved with chemotherapy. We used entire liver (n = 5), left lateral segment from cadaveric donor (n = 3), living related donor (n = 3; 2 segments II-III and 1 right lobe) and left lateral segment from split liver (n = 1). All children received chemotherapy prior and post transplantation following the SIOPEL protocol. We analysed procedure tolerance, survival, recurrence rate, disease-free period and risk factors for adverse evolution., Results: All patients overcame LTX and no early graft loss was recorded. Two cases died because of tumour relapse, 1 after primary LTX and 1 after rescue LTX (survival rate of both groups, 90% and 50%). Graft and patient survival rates at 1 year, 3 years, 5 years and 14 years were 91%, 91%, 82% and 82% respectively. The boy who presented with lung metastases developed new ones one year after LTX that were removed and he is currently free of disease. The disease-free period has a probability at 1, 3 and 5 years of 91%, 75% and 75%, respectively. Tumour tissue persistence was the only risk factor for an adverse clinical course in our series., Conclusions: LTX is a reasonable therapeutic approach for unresectable malignant liver tumours, providing outcomes comparable to those for resectable tumours. Results obtained with LTX are better when it is used as a primary treatment than when used as a rescue procedure. Proper staging and early referral to centres with enough expertise optimise the results. LTX for patients with lung metastases could be a controversial option. Living related-donor transplantation is an excellent alternative to avoid disease progression while on the waiting list for cadaveric donors.

- Abstract
Introduction: The management of children receiving small bowel grafts involves potentially life-threatening complications that affect their nutritional status. The aim of this paper was to define these factors and their influence on nutritional outcome., Patients and Methods: Patients with intestinal failure (IF) who received an isolated small bowel transplantation (SBT) or small bowel/liver transplantation (SBLT) at our hospital during the last 6 years were reviewed for weight Z-score, biochemical nutritional parameters, total parenteral nutrition (TPN) weaning, catheter-related sepsis, rejection and steroid treatment., Results: Twenty patients, 11 females and 9 males, received a SBT or a SBLT and survived the postoperative period; in the present study we only included 11 children with follow-up periods longer than 1 year. Seven males and 4 females with a mean age of 4.5 years (range, 1 to 20 years) received 6 SBLT and 5 SBT. Nine (82%) were weaned from TPN to an amino-acid or peptide enteral formula during the first 6 months after surgery. During the first year there was a significant increase in total protein from 5.11 +/- 1.8 mg/dl to 6.1 +/- 1.5 mg/dl (p < 0.05) and an increase in albumin from 3.8 +/- 0.9 mg/dl to 4.5 +/- 1.1 mg/dl (p < 0.05). There was an increase in weight Z-score in 9 patients (82%) during the first year. Mean Z-score improved from - 2.6 +/- 1 at transplant to - 1.0 +/- 0.6 (p < 0.05) after 1 year. Three patients (27.2%) had at least one rejection period, which was treated with steroids alone or in combination. Mean weight Z-score 1 year after surgery was - 0.9 +/- 0.6 for patients without rejection and - 1.24 +/- 0.8 for those with at least one rejection episode treated with steroids (p > 0.1). Four patients (36%) had at least one catheter-related sepsis episode. Mean weight Z-score 1 year after surgery was - 1.01 +/- 0.6 for patients without catheter-related sepsis and - 1.24 +/- 0.8 for those with at least one catheter-related sepsis episode (p > 0.1)., Conclusions: There was a significant improvement in weight Z-score and biochemical nutritional parameters 1 year after receiving a small bowel graft. No influence of steroids or catheter-related sepsis on children's nutritional status was noted 1 year after surgery, although this point will need further evaluation.
