Adherence to Barcelona Clinic Liver Cancer therapeutic algorithm for hepatocellular carcinoma in the daily practice: a multicenter cohort study from Argentina.

BACKGROUND AND AIM: Adherence to the Barcelona Clinic Liver Cancer (BCLC) staging algorithm for the treatment of hepatocellular carcinoma is challenging in the daily practice. We aimed to analyze adherence to BCLC along with its effect on patient survival. PATIENTS AND METHODS: A cohort study was conducted in 14 hospitals from Argentina including patients with newly diagnosed hepatocellular carcinoma (2009-2016). Adherence was considered when the first treatment was the one recommended by the BCLC. RESULTS: Overall, 708 patients were included. At diagnosis, BCLC stages were as follows: stage 0 4%, A 43%, B 22%, C 9% and D 22%. Overall, 53% of the patients were treated according to BCLC, 24% were undertreated, and 23% overtreated. Adherence to BCLC increased to 63% in subsequent treatments. Independent factors associated with adherence to BCLC were the presence of portal hypertension [odds ratio: 1.63; 95% confidence interval (CI): 1.11-2.39] and BCLC stage C (odds ratio: 0.32; 95% CI: 0.12-0.72). In a multivariable model adjusting for portal hypertension and BCLC stages, adherence to BCLC showed improved survival (hazard ratio: 0.67; 95% CI: 0.52-0.87). CONCLUSION: Adherence to BCLC represents a challenge in the daily practice, with almost half of the patients being treated accordingly, showing that the decision-making process should be tailored to each individual patient.

Isolated Intrapulmonary Vascular Dilatations and the Risk of Developing Hepatopulmonary Syndrome in Liver Transplant Candidates.

BACKGROUND: The natural history of intrapulmonary vascular dilations (IPVD) and their impact on patient outcomes in the setting of portal hypertension has only been described in small series. AIMS: To assess the development of hepatopulmonary síndrome (HPS) in patients with isolated IPVD and to evaluate outcomes of IPVD and HPS among patients evaluated for liver transplantation (LT). MATERIAL AND METHODS: Data from a prospective cohort of patients evaluated for LT with standardized screening for HPS were analyzed. IPVDs were defined as the presence of microbubbles in the left atrium > 3 cycles following right atrial opacification. HPS was defined as the presence of IPVD and hypoxemia (Alveolar-arterial gradient ≥ 15 mmHg) in the absence of concomitant cardiopulmonary disease. RESULTS: A total of 104 patients with negative contrast-enhanced echocardiogram (CE) were compared to 63 patients with IPVD and 63 patients with HPS. Only four patients were categorized as 'severe' HPS based on degree of hipoxemia (defined as PaO2 < 60 mmHg). Twenty IPVD patients were followed with ABG over a mean duration of 21 months (range 9-43), of whom 7 (35%) subsequently met HPS criteria. Overall unadjusted survival from the time of LT evaluation using multi-state survival models that accounted for pre- and post-LT time was not statistically different among the three groups (negative CE, IPVD, and HPS; p > 0.5). CONCLUSIONS: Patients with IPVD appear to have a substantial risk of developing oxygenation impairment over time and progress to HPS. In our cohort, survival in patients with HPS and isolated IPVD is not different when compared to those without IPVDs.

Predicting early discharge from hospital after liver transplantation (ERDALT) at a single center: a new model.

BACKGROUND & RATIONALE: Limited information related to Liver Transplantation (LT) costs in South America exists. Additionally, costs analysis from developed countries may not provide comparable models for those in emerging economies. We sought to evaluate a predictive model of Early Discharge from Hospital after LT (ERDALT = length of hospital stay ≤ 8 days). A predictive model was assessed based on the odds ratios (OR) from a multivariate regression analysis in a cohort of consecutively transplanted adult patients in a single center from Argentina and internally validated with bootstrapping technique. RESULTS: ERDALT was applicable in 34 of 289 patients (11.8%). Variables independently associated with ERDALT were MELD exception points OR 1.9 (P = 0.04), surgery time < 4 h OR 3.8 (P = 0.013), < 5 units of blood products consumption (BPC) OR 3.5 (P = 0.001) and early weaning from mechanical intubation OR 6.3 (P = 0.006). Points in the predictive scoring model were allocated as follows: MELD exception points (absence = 0 points, presence = 1 point), surgery time < 4 h (0-2 points), < 5 units of BPC (0-2 points), and early weaning (0-3 points). Final scores ranged from 0 to 8 points with a c-statistic of 0.83 (95% CI 0.77-0.90; P < 0.0001). Transplant costs were significantly lower in patients with ERDALT (median $23,078 vs. $28,986; P < 0.0001). Neither lower patient and graft survival, nor higher rates of short-term re-hospitalization and acute rejection events after discharge were observed in patients with ERDALT. In conclusion, the ERDALT score identifies patients suitable for early discharge with excellent outcomes after transplantation. This score may provide applicable models particularly for emerging economies.
