RESUMO
The vast majority of patients with hepatocellular carcinoma (HCC) in China originate from hepatitis B cirrhosis, while 90% of cirrhotic patients may develop portal hypertension, and the HCC patients with portal hypertension account for 15%-30%. Portal hypertension is a group of clinical syndromes characterized by elevated portal venous pressure and formation of portal-systemic collateral circulation, and it is one of the most important complications of liver cirrhosis. HCC and portal hypertension affect each other, and portal hypertension seriously affects the prognosis of HCC patients. The development of systemic treatment regimens for HCC provides more treatment options for patients with advanced HCC, including molecular-targeted drug therapy, immunotherapy, and chemotherapy. Different systemic therapeutic drugs for HCC have different impacts on portal hypertension, and this article reviews the effect of commonly used systemic therapeutic drugs for HCC on portal hypertension.
RESUMO
Objective:To investigate the current status of interventional radiology discipline in the provincial-level and national cancer hospitals of China, and to provide supportive data for the future systematic construction of interventional radiology.Methods:A questionnaire was used to survey 32 provincial and national cancer hospitals of China. The survey included data such as discipline settings, medical treatment, medical education, and scientific research. Then descriptive statistical analysis was performed based on the data.Results:All 32 provincial and national cancer hospitals of China had interventional radiology services and were equipped with independent wards; the deployment rates of DSA, ultrasound, CT, and radiofrequency ablation equipments were: 100%(32/32), 81.3%(26/32), 40.6%(13/32), and 75.0%(24/32), respectively. Of all 32 hospitals, 27 (84.4%) had performed more than 1 000 interventional operations per year. The proportion of hospitals that had interventional subspecialties was 21.9% (7/32). As for the interventional radiology doctors in these hospitals, the ratio of doctors with a background of medical imaging specialty was 69.6%(256/368); the proportion of doctors with ages ≤ 45 years old was 72.0%(265/368); and the ratio of doctors with a master degree was 79.9%(294/368). Among the 32 hospitals, 22 (68.8%) had more than 500 000 yuan research funds in intervention radiology discipline, and 71.9%(23/32) had intervention radiology discipline postgraduate tutors.Conclusions:The overall development of interventional radiology discipline in provincial-level and national cancer hospitals is good. The discipline development pattern might set a good example for interventional radiology discipline construction in general hospitals.
