RESUMO

OBJECTIVE: Hepatocellular carcinoma (HCC) incidence among elderly patients is increasing. Trans-arterial chemo-embolization (TACE) prolongs survival in selected HCC patients. The safety and efficacy of TACE in elderly patients has not been extensively studied. The objective of this study was to assess the safety and efficacy of TACE in elderly patients (older than 75) with HCC. DESIGN: Combined HCC registries (Spain, Italy, China and Israel) and cohort design analysis of patients who underwent TACE for HCC. RESULTS: Five hundred and forty-eight patients diagnosed and treated between 1988 and 2010 were included in the analysis (China 197, Italy 155, Israel 102 and Spain 94,). There were 120 patients (22%) older than 75 years and 47 patients (8.6%) older than 80. Median (95% CI) survival estimates were 23 (17-28), 21 (17-26) and 19 (15-23) months (P=0.14) among patients aged younger than 65, 65-75 and older than 75 respectively. An age above 75 years at diagnosis was not associated with worse prognosis, hazard ratio of 1.05 (95% CI 0.75-1.5), controlling for disease stage, sex, diagnosis year, HBV status and stratifying per database. No differences in complication rates were found between the age groups. CONCLUSIONS: TACE is safe for patients older than 75 years. Results were similar over different eras and geographical locations. Though selection bias is inherent, the results suggest overall adequate selection of patients, given the similar outcomes among the different age groups.

RESUMO

BACKGROUND: Squamous cellular carcinoma antigen (SCCA) is overexpressed in hepatocellular carcinoma (HCC) tissue and in sera of HCC patients. Our aim was to assess hepatic SCCA immunostaining in a series of HCCs and to correlate its presence with cell proliferation, apoptosis and clinical outcome. METHODS: Sixty-one HCC patients were included. Liver specimens were obtained either by biopsy (n = 17) or surgically (resection 27, transplantation 17). Immunostaining for AFP, Ki-67, SCCA and TUNEL assay were performed. RESULTS: SCCA staining was detected in 83.6% of specimens. A statistical significant correlation was found between negative SCCA staining and mortality (p = 0.026) and a higher immunostaining score for Ki67 (p = 0.017). Positive SCCA staining was associated with well and moderate differentiated tumors (p = 0.022). Using multiple logistic regression analysis, Ki67 and TUNEL assay were found to be significant independent predictors of negative SCCA immunostaining. The area under the receiver operator characteristic curve was 0.87. Kaplan-Meier survival analysis revealed a significant difference between the patient group with positive versus negative SCCA immunostaining relating to survival time (p = 0.0106). Cox proportional hazard regression analysis demonstrated that Ki67 immunostaining and liver transplantation or resection were independently associated with mortality. CONCLUSIONS: SCCA is overexpressed in HCC. SCCA status is associated with cell proliferation, apoptosis and survival. SCCA and Ki67 staining can predict survival. Our study results support a potential association of negative SCCA expression with other markers of poor outcome in HCC. More studies are needed to clarify the role of SCCA in HCC and expand the knowledge of the SCCA antigen in HCC patients.

RESUMO

The Israeli population does not meet its transplantation organ needs. Therefore, liver transplantation (LTX) candidates are sometimes transported to centers abroad. We aimed to assess the demographic and clinical issues concerning this policy. Records of all candidates transported (2000-2004) were retrospectively reviewed. Data included etiology, disease severity, outcome, distances traveled and destinations, and medical complication arising en route. Forty-three candidates were transported overseas: 12 patients with fulminant hepatic failure (FHF) and 31 with cirrhosis. Average MELD score was 19.94, and the APACHE II score for patients with FHF was 20.5. Destinations included the United States, Colombia, Belgium, Germany, China, and Italy. Average distance traveled was 4,660 miles. Two patients were intubated and sedated during flight. All patients safely reached their destinations: 8 died prior to transplantation, 5 died after transplantation, 3 are awaiting transplantation, 3 recovered spontaneously, and the rest successfully underwent transplantation and returned home. In conclusion, our results suggest that long-distance transportation of patients awaiting liver transplantation is safe and technically feasible provided precaution measures are taken. Therefore, allocation regions may be broadened to include larger and more distant populations.
