Combination of TACE and Sorafenib Improves Outcomes in BCLC Stages B/C of Hepatocellular Carcinoma: A Single Centre Experience

ABSTRACT Background & Aim. Transarterial chemoembolization (TACE) or sorafenib is recommended for hepatocellular carcinoma BCLC stages B and C respectively. We studied the role of combination of TACE and sorafenib in BCLC stages B/C. Material and methods. We undertook an observational study on a cohort of cirrhotics with HCC from August 2010 through October 2014. Patients in BCLC stages B/C who had received TACE and/or sorafenib were included. mRECIST criteria were used to assess tumor response. The primary end point was overall survival. Results. Out of 124 patients, 47.6% were in BCLC-B and 52.4% in BCLCC. Baseline characteristics were comparable. The predominant etiology was cryptogenic (37.2% and 38.5%, p = NS). 49.1% in BCLC-B and 56.9% in BCLC-C had received TACE+sorafenib. In BCLC-B, the overall survival improved from 9 months (95% CI 6.3-11.7) using TACE only to 16 months (95% CI 12.9-19.1) using TACE+sorafenib (p < 0.05). In BCLC-C, addition of TACE to sorafenib improved the overall survival from 4 months (95%CI 3-5) to 9 months (95%CI 6.8-11.2) (p < 0.0001). As per mRECIST criteria, patients on TACE+sorafenib had reduced progressive disease (37.8% vs. 83.3%), improved partial response (43.2% vs. 3.3%) and one had complete response compared to those on sorafenib alone (p < 0.0001) in BCLC-C but not in BCLC-B group. Hand foot syndrome was noted in 27.7% patients on sorafenib and post TACE syndrome in 80.2% patients, but both were reversible. No major adverse events were noted. Conclusion. TACE+sorafenib was more effective than TACE or sorafenib alone in HCC BCLC stages B or C with a significant survival benefit and improved tumour regression especially in BCLC-C patients.

Prevalence and risk factors for bacterial skin infection and mortality in cirrhosis.

BACKGROUND: Bacterial infections are often associated with significant morbidity and mortality in cirrhosis. The common practice of outdoor barefoot walking in the developing world may predispose cirrhotic individuals to skin infection. Aims. To determine the prevalence, risk factors, spectrum of infective organism and outcome of bacterial skin infection in cirrhosis. METHODS: Consecutive newly diagnosed patients with cirrhosis (n = 200) between September 2007 and September 2008 were studied. Patients with congestive heart failure (n = 50) and chronic kidney disease (n = 50) on follow up at the same institution served as controls. Baseline demographic details, history of outdoor barefoot walking, details of skin infection along with cultures from skin and blood were obtained. The association between patient factors and risk of skin infection was evaluated using logistic regression. RESULTS: Alcoholism was the predominant etiology for cirrhosis. (50%) Most of them were of Child B cirrhosis. Walking on barefoot was found to be similar in cases and controls. 21(10.5%) patients with cirrhosis had skin infection, three fourth of them had a history of barefoot walking. None of the controls had skin infection. Cellulitis with hemorrhagic bullae, leg ulcers, infected callosity and abscess were observed. The infective organism could be isolated in 17 patients. Escherichia coli was the most frequent organism identified. Logistic regression showed outdoor barefoot walking and serum albumin < 2.5 gm/dL as risk factors for skin infection. Four patients died. CONCLUSION: The prevalence of skin infection in cirrhosis was 10.5% with a mortality of 19%. Escherichia coli was the commonly implicated organism. Outdoor barefoot walking was a strong risk factor for skin infection in cirrhosis.

Hepatopulmonary syndrome - past to present.

Hepatopulmonary syndrome (HPS) is the one of the complication of liver cirrhosis with portal hypertension, irrespective of etiology, age and sex. It has also been observed in non cirrhotic portal hypertension and in acute hepatic conditions. Presence of hypoxemia or abnormal alveolar arterial oxygen tension with intrapulmonary vasodilation in liver cirrhosis is termed as HPS. Contrast echocardiogram is the better screening tool to demonstrate intrapulmonary shunt. Clinicians should be aware of other common chronic pulmonary and cardiac comorbid conditions, in particular COPD, tuberculosis, bronchial asthma and idiopathic pulmonary fibrosis, etc. which may coexist with HPS. There is no specific clinical finding to diagnose but digital clubbing, cyanosis, dyspnoea, platypnoea, and spider naevi are more common among cirrhosis with HPS. The presence of HPS independently worsens prognosis of cirrhosis. Even though number of mechanisms have been proposed to explain arterial hypoxemia in HPS, role of nitric oxide is the major one along with cytokines. Liver transplantation is the choice of treatment though mortality is comparatively high. There is no still effective recommended medical therapy to reverse this condition and anti cytokine/ nitric oxide inhibitors, etc are under preliminary stage.
