Comparison of clinical and pathological staging and long-term results of liver transplantation for hepatocellular carcinoma in a single transplant center.

Liver transplantation (OLT) is a treatment for hepatocellular carcinoma (HCC) superimposed on cirrhosis provided that the disease meets defined criteria. The aim of the study was to evaluate our experience with respect to clinical and pathological staging and long-term results. From 1996 to 2005, 50 patients underwent OLT for HCC including 43 men (86%) and seven women (14%) of median age 57 years (range 37 to 67). All patients fulfilled the Milan criteria. The HCC diagnosis was based on preoperative imaging and alpha-fetoprotein levels; no tumor biopsy was performed. Upon histological examination of the resected specimens, we discovered 6 (12%) incidentalomas and 8 (16%) cases of no HCC. Finally we had 42 "true" HCC. Twenty-six patients (52%) have been downstaged and 10 (20%) upstaged by preoperative imaging; 15% were pT1, 45% were pT2, 27% pT3, and 13% pT4a. Twenty-six percent of cases exceeded the Milan criteria. One patient (pT4a) with microvascular invasion died of pulmonary metastases at 14 months after transplantation. No HCC recurrences within the liver have been encountered at a median follow-up of 20 months (range 0 to 80 months). Overall the estimated 1-, 3-, and 5-year survival rates were 83%, 77%, and 72%, respectively. One-, 3-, and 5-year estimated survival rates were 87%, 75%, and 75% for pT1, and pT2, and 75%, 67%, and 67% for pT3 and pT4a, respectively (P = .99). Based on our experience OLT for HCC has long-term results comparable to those without HCC despite the presence of a significant number of cases exceeding the Milan criteria upon pathological staging.

De novo malignancies after kidney and liver transplantations: experience on 582 consecutive cases.

De novo malignancies after transplantation are a growing problem of solid organ transplant recipients, due to longer survival follow-up under chronic immunosuppression. The aim of this study was to analyze a population of 582 consecutive kidney (n = 382) and liver (n = 202) transplant recipients, who survived at least 12 months after transplantation, at a single transplant center for the development of de novo cancers. The incidence of de novo malignancies was 7% after both renal and liver transplantation. The median elapsed time from transplant to the diagnosis of de novo malignancy was 45 months (range 3 to 220) months for kidney and 37 months (range 12 to 101 months) for liver transplants. Skin cancers were the most common within renal recipients, while gastroenteric cancers were more frequently encountered in liver transplants. Oropharyngeal and upper digestive tract tumors were always associated with a history of chronic alcohol consumption in liver recipients. Liver transplant recipients treated for acute rejection had a worse cancer prognosis than patients without rejection 1- and 2-year survivals 83% and 63% versus 36% and 17% (P = .026). The estimated 1- and 2-year survival rates for all types of de novo malignancies were 79% and 66%, including 64% and 51% for solid organ tumors versus 89% and 89% for skin cancers and posttransplant lymphoproliferative disorder (PTLD) (P = .17) in renal transplants and 70% and 42%, including 57% and 28% for solid organ tumors versus 85% and 64% for skin cancers and PTLD (P = .43) in liver transplants respectively.

Laparoscopic cholecystectomy in children with chronic hemolytic anemia. Is the outcome related to the timing of the procedure?

BACKGROUND: The aim of this study was to evaluate whether the outcome in children with chronic hemolytic anemia (CHA) and cholelithiasis undergoing laparoscopic cholecystectomy (LC) is related to the operation timing. METHODS: From June 1995 to December 2004, 46 children with CHA were referred to our division of surgery for cholelithiasis. All 46 children were asymptomatic at the time of the first visit, and an elective LC was proposed to all of them before the onset of symptoms. The operation was accepted in the period of study by 24 children and refused by 22. The patients were divided into three groups (group A, asymptomatic; group B, symptomatic; and group C, emergency admitted) depending on clinical presentation and operation timing, and the respective outcomes were compared. RESULTS: Elective LC in asymptomatic children (group A) is safe with no major complications reported. In children who refused surgery (groups B and C), we observed four sickle cell crises, four acute cholecystitis, and two choledocholithiasis, and all these complications were related to waiting. Two sickle cell crises occurred in symptomatic children waiting for surgery during biliary colic. The risk of emergency admission in children with cholelithiasis and CHA awaiting surgery was found to be high: 28% of the children admitted in emergency after a mean of 32 months (range, 22-36). Morbidity rate and postoperative stay increased when children with hemoglobinopathies underwent emergency LC. CONCLUSIONS: Elective LC should be the gold standard in children with CHA and asymptomatic cholelithiasis in order to prevent the potential complications of cholecystitis and choledocholithiasis, which lead to major risks, discomfort, and longer hospital stay.

[Radiofrequency-assisted hepatic resection--first experience].

AIMS: Intra-operative blood loss during liver, resection remains a major concern due to its association with higher postoperative complications and shorter long-term survival. The aim of this study was to assess the feasibility and safety of a novel concept for liver resection using a Radio-Frequency energy assisted technique. METHODS: From January 2001 to January 2002, 27 patients were operated on using Radio-Frequency energy assisted liver resection. Radio-Frequency energy was applied along the resection edge to create a 'zone of desiccation' prior to resection with a scalpel. RESULTS: Median resection time was 47.5 minutes (range 30-110). The median blood loss during resection was 30 mls (range 15-992) and mean pre-operative and post-operative haemaglobin values were 13.5 g/dL (SD+1.7) and 11.6 g/dL (SD+1.4) respectively. No blood transfusion was registered, nor was any mortality observed. There was one post-operative complication: a sub-phrenic abscess. Median post-operative stay was 8 days (range 5-86). CONCLUSION: Liver resection assisted by RF energy is feasible, easy and safe. This novel technique offers a new method for 'transfusion-free' resection without the need for sutures, ties, staples, tissue glue or admission to Intensive Care Unit.

[Cephalometric evaluation of soft tissue in orthodontic treatment planning].

The starting point of an orthodontic treatment is represented by a complete and a correct diagnosis. Therefore the Authors investigated the need of a soft tissue analysis that is related to the University of Connecticut cephalometric analysis. The authors emphasize the importance of the vertical, horizontal and angular index in some patients with values different from the normal values. The soft tissue and esthetic data allow to finalize the orthodontic treatment to the esthetic improvement (besides occlusal) for the patients needs.
