RESUMO
BACKGROUND: Approximately 10-40% of hepatocellular carcinoma (HCC) patients have definite vascular invasion at the time of diagnosis. Without curative treatment options, these patients have an abysmal prognosis with a median survival of only a few months following systemic therapy. However, supportive evidence of combining multiple locoregional treatments with systemic therapy is limited. This study compared the outcomes of sorafenib alone versus multimodality therapy with sorafenib, radiotherapy (RT), and transarterial chemoembolization (TACE) in advanced HCC patients with macrovascular invasion (MaVI). METHODS: The process took place over a nine-year period between March 2009 and October 2017, wherein 78 HCC patients with MaVI who underwent either sorafenib therapy alone (n = 49) or combined sorafenib/RT/TACE (n = 29) therapy were chosen for the retrospective study. We compared the overall survival (OS) between the two groups using the Cox regression hazard model and adjusted imbalances using propensity score matching (PSM). RESULTS: At the last follow-up, 76 patients had died, with a median follow-up time of 4.8 months for all patients and 31 months for those who were alive. Patients treated with sorafenib/RT/TACE had superior OS compared to those treated with sorafenib alone, showing a median survival of 9.3 vs. 2.7 months and a one-year survival of 37.1% vs. 6.1% (p < 0.001). In the multivariable analysis, new diagnosis or recurrence of HCC and treatment modalities (sorafenib alone vs. sorafenib/RT/TACE) were independent prognostic factors for OS. Compared to patients treated with sorafenib alone, significantly better OS was further verified using PSM (p < 0.001) in patients who received multiple therapeutic modalities. CONCLUSION: Multimodality therapy with sorafenib/RT/TACE increased OS threefold versus sorafenib therapy alone in HCC patients with MaVI. This study offers promising benefits of combined locoregional and systemic therapy for advanced HCC in current patient management and prospective clinical trials.
RESUMO
Heart failure (HF) and cancer have similar risk factors. HMG-CoA reductase inhibitors, also known as statins, are chemoprotective agents against carcinogenesis. We aimed to evaluate the chemoprotective effects of statins against liver cancer in patients with HF. This cohort study enrolled patients with HF aged ≥20 years between 1 January 2001 and 31 December 2012 from the National Health Insurance Research Database in Taiwan. Each patient was followed to assess liver cancer risk. A total of 25,853 patients with HF were followed for a 12-year period; 7364 patients used statins and 18,489 did not. The liver cancer risk decreased in statin users versus non-users (adjusted hazard ratio (aHR) = 0.26, 95% confidence interval (CI): 0.20-0.33) in the entire cohort in the multivariate regression analysis. In addition, both lipophilic and hydrophilic statins reduced the liver cancer risk in patients with HF (aHR 0.34, 95% CI: 0.26-0.44 and aHR 0.42, 95% CI: 0.28-0.54, respectively). In the sensitivity analysis, statin users in all dose-stratified subgroups had a reduced liver cancer risk regardless of age, sex, comorbidity, or other concomitant drug use. In conclusion, statins may decrease liver cancer risk in patients with HF.
RESUMO
BACKGROUND: Hepatocellular carcinoma accounts for approximately 90% of primary liver cancers and hepatitis virus was believed to have the potential for altering the pathogenesis of arteriosclerosis. However, the influence of the hepatitis virus on coronary artery disease or cerebral vascular disease remains unclear. This study used the Taiwan National Health Insurance Research Database to clarify the virus-associated risk of coronary artery disease and cerebral vascular disease in patients with hepatocellular carcinoma (HCC). METHODS: A total of 188,039 HCC individuals, age 20 years or older, were enrolled from the Longitudinal Health Insurance Database between 2000 and 2017 for cohort analysis. A total of 109,348 with hepatitis B virus (HBV) infection, 37,506 with hepatitis C virus (HCV) infection, 34,110 without HBV or HCV, and 7075 with both HBV and HCV were recorded. Statistically, propensity score matched by sex, age, and index year at a ratio of 15:5:5:1 and a sensitivity test using multivariable Cox regression were used. RESULTS: The risk of coronary artery disease in the HCV-related HCC group was 1.516-fold (95% CI: 1.328-2.034, p < 0.001) higher than in the HBV-related HCC group, followed by the HBV/HCV-related HCC group and the non-B/C HCC group; the cerebral vascular disease risk in the HCV-related HCC group was 1.467-fold higher than in the HBV-related HCC group (95% CI: 1.335 to 1.786, p < 0.001), followed by the HBV/HCV-related HCC group and the non-B/C HCC group. CONCLUSION: Hepatitis C virus infection was found to have a higher risk of developing coronary artery disease or cerebral vascular disease in patients with hepatocellular carcinoma. For patients with hepatocellular carcinoma, our findings warrant the importance in preventing artherosclerotic disease in the setting of hepatitis C virus infection.
