ABSTRACT
At present,the combined interventional therapy that is based on transcatheter arterial chemoembolization (TACE) technique can control the progression of primary hepatocellular carcinoma (PHC)in different degrees,at the same time the clinical objectives,such as relieving portal hypertension,eliminating portal vein occlusion,controlling refractory ascites and lowering upper gastrointestinal bleeding probability,can be reliably achieved.Thus,the quality of life of the patients can be effectively improved and the survival time will be reliably prolonged.This paper aims to make a comprehensive review about the medical articles concerning TACE combined with other interventional therapies for PHC complicated by portal vein tumor thrombus,which have been published both at home and abroad in recent years,in order to provide practical help for clinical diagnosis and treatment of PHC.
ABSTRACT
Objective To explore the relationship of MDR1 and its encoded product P-gp expressions with clinical efficacy of transcatheter arterial chemoembolization (TACE)in primary liver cancer and their clinical significance.Methods We selected 108 patients with primary liver cancer who came to our hospital between June 2010 and June 2013 as observation subjects.Meanwhile 50 healthy people in our hospital for liver biopsy were selected as controls.MDR1 mRNA level in observation group and control group was determined by real-time quantitative PCR.P-gp protein level was analyzed by immunohistochemistry.According to P-gp level,the 108 patients were divided into drug-resistance groups and non-resistance group;the relationship between P-gp expression level and clinical efficacy was analyzed.Results MDR1 mRNA level in liver tissues significantly enhanced in observation group compared with that in control group (P <0.05).In observation group 32 patients had the ratio of MDR1 mRNA level-normal level of more than 2 and 76 patients had the ratio of MDR1 mRNA level-normal level of less than 2. Immunohistochemistry revealed that MDR1 encoded product P-gp was brownish yellow, mainly expressed in the cell surface of liver cancer cells.There were 35 P-gp protein-negative patients (non-resistance group)and 73 positive patients (resistance group).Clinical efficacy was significantly higher in non-resistance group (74.28%)than in resistance group (43.28%)(P <0.05).The 1 year and 2-year cumulative survival rates were 54. 12% and 27.40% in resistance group and 77.14% and 42.86%% in non-resistance group.They were significantly higher in the latter group (P <0.05 ).Conclusion The overexpressed MDR1 encoded product P-gp in primary liver cancer is associated with multidrug resistance in tumor chemotherapy,suggesting that P-gp can be used as one of the guiding clinical markers of chemotherapy.
ABSTRACT
Objective To explore the imaging diagnostic value of gastrointestinal stromal tumor(GIST).Methods The retrospective study on GIST proved by operation and pathology in 11 cases was done.There were pneumobarium double contrast examination in 10 cases,CT scanning in 4 cases,superior mesenteric ateriography in 2 cases and fiberoptic endoscopy in 7 cases.Results The locations of tumors at gastric were 7 cases,intestinal 2,lipper and row oseophagus to gastric cardiac in 1,respectively.The detective rate of GIST was 100%,75%,100% and 100% respectively by pneumobarium double contrast examination,CT,arteriography and fiberoptic endoscopy.Conclusion Pneumobarium double contrast examination and fiberoptic endoscopy are important methods for diagnosis of GIST.CT and arteriography can better show the location of tumors and differential diagnosis of benign and malignant of tumor.
