A case is a male in his 50's. He received hepatic resections twice for hepatocellular carcinoma. Recurrence was pointed out in the residual liver with tumor thrombus to the right branch of the portal vein. The serum level of AFP was 648 ng/ml. We performed transhepatic arterial embolization (TAE) with Epi-ADM, CDDP, Lipiodol and spongel through the right hepatic artery before re-hepatectomy. Posterior segmentectomy with an extraction of portal vein thrombus was performed. Pathological findings showed complete necrosis not only in the main tumor but in the portal vein thrombus also. He is alive for more than 5 years without recurrence after surgeries following pre-operative TAE. 相似文献

The patients of unresectable cholangiocellular carcinoma (CCC) have extremely poor prognosis. Case 1 was a 72-year-old male who had CCC in the left lobe of liver with intrahepatic metastasis. From June 2003, he received hepatic arterial infusion chemotherapy (FAP: 5-fluorouracil 250 mg/day continuous infusion, day 1-5, adriamycin 10 mg/day, day 1, and CDDP 10 mg/day, day 1). After 5 courses, abdominal CT revealed that the main tumor had regressed. Case 2 was a 66-year-old male who had CCC with portal vein tumor thrombus of anterior branch (Vp2). He received FAP arterial infusion chemotherapy that was a same regimen as with the case 1 patient. After 5 courses were administered, Abdominal CT revealed that the size of the main tumor at S8 had not changed, and that portal vein tumor thrombus had disappeared. In both cases, there was no complication related to the chemotherapy. They are alive for more than 1 year after chemotherapy had started. FAP hepatic arterial infusion chemotherapy might be promising as an effective therapy for non-resectable CCC without extra hepatic metastasis. 相似文献

A 61-year-old male was admitted for advanced hepatocellular carcinoma (HCC) with multiple lung metastases and tumor thrombus in the portal vein and superior vena cava. At first, we planned to perform transcatheter arterial embolization (TAE) to avoid the rupture of the liver tumor. But, due to the severe liver dysfunction, ie Child-Pugh C and 36% ICG R15, hepatic arterial infusion (HAI) of epirubicin 40 mg was performed. After that, the patient was followed at the outpatient ward and his general condition has gradually improved without a special treatment. At the present, one year and ten month after HAI, the serum alpha-fetoprotein (AFP) is almost within normal limits and CT scans show that HCC with multiple lung metastases, and tumor thrombus in the portal vein and superior vena cava almost disappeared. Although, spontaneous regression of HCC was a rare phenomenon, it might have played a major role in the good anticancer efficacy of this patient as well as high anti-cancer agent sensitivity of his liver tumor. 相似文献

We reported a case of hepatocellular carcinoma (HCC) with portal venous tumor thrombus (PVTT) (Vp2) successfully treated by transcatheter arterial chemoembolization (TACE), and the tumor showed complete response and the patient survived for 28 months. A 67-year-old male was diagnosed with HCC in the area of subsegment 5 with PVTT from the P5 to the posterior branch. He was treated by segmental TACE. The tumor markers decreased within normal limits, and localized hepatic infraction in the subsegment 5 and atrophy of the PVTT were recognized. He survived for 28 months with no tumor recurrence after the first TACE. This case suggested that embolization might play a part of treatment to HCC with PVTT, if the liver function was preserved and the lesion of liver infraction was limited. 相似文献

Hepatocellular carcinoma (HCC) with vascular invasion and/or intrahepatic metastasis (IM) has a poor prognosis, so advanced HCC may be considered as a contraindication for hepatectomy. We experienced a case of HCC with hepatic venous and portal venous tumor thrombus and multiple IM who survived over 1 year after the operation with combined locoregional chemotherapy. (Case): A 67-year-old male patient was diagnosed with HCC with extracapsular invasion after transarterial embolization (TAE). CT scan revealed the HCC had a right portal venous tumor thrombus and multiple IM. Posterior lobectomy and thrombectomy of hepatic venous and portal venous tumor thrombus and placement of portal venous catheter ware performed. From the first day after operation the patient received continuous intravenous and intraportal 5-FU for 3 weeks. At the first month after operation, TAE and PEIT were given against residual IM. After discharge the patient received hepatic arterial infusion chemotherapy (MTX/CDDP/5-FU/Leucovorin). Fourteen months after operation, the patient is surviving in good physical condition. 相似文献

The patient, a 79-year-old woman, underwent distal gastrectomy for gastric cancer in November 2002. The lesion was judged to be T1 N0H0POM0 and fStage IA. A hepatohilar tumor was found 1 year after gastrectomy by CT scan. Radiological examinations revealed a presence of right portal vein stenosis and left portal vein obstruction due to hepatohilar bile duct cancer. Surgical treatment was considered to be difficult because of the consequence of the tumor involved in the right hepatic artery. We performed hepatic arterial infusion chemotherapy of 5-fluorouracil 1000 mg/body/week for 8 courses through the reservoir catheter. Radiation therapy was delivered concurrently with hepatic arterial infusion. The condition of the patient was good after receiving 40 Gy, Three months after the additional 20 Gy radiation, the tumor was markedly reduced in size, and was not detected 7 months thereafter. MRI showed no recurrence for three and a half years since chemo-radiation. 相似文献

The study subjects were 49 patients with hepatocellular carcinoma. Twenty-nine patients underwent hepatic arterial blood flow block via thrombosis of the cancer-bearing area with a gelatin sponge, while the other 20 patients underwent a combination of hepatic arterial block and partial blood flow block of the portal vein with a hepatic venous balloon. Percutaneous microwave coagulation therapy (PMCT) was performed on these patients according to the type of hepatic blood flow block, and the diameters of the coagulation areas in the two groups were compared using CT images taken under portal venography. The 29 patients who underwent hepatic arterial block (A-PMCT) had a mean tumor diameter of 19.2 +/- 8 mm, while the 20 patients who underwent hepatic arterial and hepatic venous block (AV-PMCT) had a mean tumor diameter of 25.3 +/- 8.3 mm. PMCT was performed at 60 W. The mean coagulation time and the mean coagulation diameter were 4.2 +/- 1.1 min and 36.3 +/- 12.3 mm, respectively, for the A-PMCT group and 5.5 +/- 1.8 min and 43.9 +/- 9.8 mm, respectively, for the AV-PMCT group. A comparison of the coagulation diameters indicated that the AV-PMCT group had a significantly greater coagulation area than the A-PMCT group (p < 0.05). 相似文献

A 56-year-old man was revealed to be HCC with portal vein tumor thrombus. Curative operation was impossible because we recognized many daughter lesions in the liver. Tumor marker was very high. DSM-TACE was conducted as the first line therapy. There was no remarkable side effect. After two-course, the size of HCC was decreased in CT and tumor marker was normalized. Generally speaking, a prognosis of HCC with portal vein tumor thrombus is poor. Hence, DSM-TACE is one of the effective therapies for HCC with portal vein tumor thrombus. 相似文献

Objective: To investigate the imaging features of primary hepatic leiomyoma. Methods: 3 patients of primary hepatic leiomyoma confirmed by pathology without immunodeficiency were retrospectively analyzed about CT and MRI findings, clinical and pathological correlation. 2 cases had routine CT scan, 2 cases had routine MRI. Results: 2 case CT scans showed low-density lesions, 2 cases MRI showed lesions with long T1 and long T2 signal. One case of uniform density and signal showed homogeneous enhancement; two cases showed uneven density and signal, of which one case was inhomogeneous enhancement. 3 cases presented pseudocapsule without hepatic cirrhosis and venous tumor thrombus. Pathology showed spindle tumor cell proliferation and capillary hyperplasia; one case showed central hyalinization and one case central liquefaction necrosis. Conclusion: Primary hepatic leiomyoma is a hypervascular tumor, and CT and MRI help in the diagnosis. 相似文献

In February, 1996, a 73-year-old male with liver dysfunction was admitted to our hospital for further examination and treatment of liver tumor. The liver tumor was revealed by imaging examination, which was mainly in the S4-S8 of liver with a thrombus growing from the right anterior branch to the right branch of the portal vein, and from the right hepatic vein to the inferior vena cava and right atrium. The serum AFP and PIVKA-II levels were elevated to 3.610 ng/ml and 54 AU/ml, respectively. The patient was diagnosed as having hepatocellular carcinoma, and was treated by arterial administration of anticancer drugs (epirubicin hydrochloride, mitomycin C and carboplatin) and TAE. Though the main tumor (S4-S8 of liver) was reduced by TAE, the portal and atrial tumor thrombus did not respond. One month after TAE (20 May, 1996), the first arterial administration of Lipiodol-SMANCS was given, followed by 4 successive procedures with an interval of about 1.5 months (total dose 15 mg), resulting in remarkable tumor thrombus shrinkage and reduction of AFP levels to 80 ng/ml. This case shows that arterial administration of SMANCS may be one of the effective treatments for hepatocellular carcinoma, even with tumor thrombus of hepatic vein, IVC and right atrium. 相似文献

A 50-year-old man having an advanced hepatocellular carcinoma (HCC) was admitted to our institution. An abdominal computed tomogram showed infiltrative mass in the right liver with tumor thrombus invading into the main trunk and contralateral branch of the portal vein. Repetitive transcatheter arterial chemoembolization reduced a tumor size and shrunken portal vein tumor thrombus. The tumor marker levels such as AFP and PIVKA-II decreased. During follow-up, he was diagnosed as having an impending rupture of HCC with acute abdominal pain. He was successfully treated with interventional technique. He died of liver failure 66 months after the first treatment. Although he had a highly advanced HCC with tumor thrombus of the portal vein, repetitive transcatheter arterial chemoembolization therapy may prolong survival. 相似文献

A 66-year-old-man with a right huge hepatocellular carcinoma (HCC) extending into both the right portal vein and the right atrium underwent transcatheter arterial embolization (TAE) via the right hepatic artery. Prior to the TAE, a temporary inferior vena cava (IVC) filter was placed suprarenally for prevention of pulmonary tumor emboli. When we replaced the temporary IVC filter with a new one 7 days after the TAE, the filter which was pulled out of the IVC captured a fragment of the tumor thrombus. A histopathological specimen demonstrated only ghost cells. The patient has been followed at our outpatient clinic without any tumor thrombus or pulmonary infarction for 13 months after this procedure. 相似文献

The patient was a 67-year-old man who had been operated for eshophageal cancer 4 years ago. He was diagnosed as intrahepatic cholangiocarcinoma by CT after 2 years of the operation. After admission to our hospital, he was treated by hepatic arterial infusion chemotherapy with CDDP, levofolinate calcium (L-LV) and 5-FU with chronomodulation. After a few more months of the treatment, abdominal CT revealed that the size of hepatic tumor decreased remarkably. There were no side effects without bone marrow suppression (grade 1). It seemed that hepatic arterial infusion chemotherapy with chronomodulation may be an effective strategy against intrahepatic cholangiocarcinoma in high risk case. 相似文献
