Methods： 72 patients with advanced primary liver cancer with no indication for surgery received intraperitoneal chemotherapy in combination with other therapies including transcatheter arterial chemoembolization （TACE）, radiofrequency catheter ablation （RFA）, percutaneous ethanol injection therapy （PELT） and radiotherapy. Of them, 29 cases were complicated with hilar or retroperitoneal multiple lymph node metastases, 14 with portal vein embolus, 15 with intrapedtoneal and diaphragmatic metastases, 6 with chylous ascites, one with cancerous ascites, and 7 with suspected cancerous ascites （referring to large amounts of ascites without hypoproteinemia while exfoliative cytology of the ascites was positive）. The mean maximum tumor size was 8.2 cm in diameter. Liver function at the initial treatment was Child A in 53 cases, and Child B in 19 cases. I ntrapedtoneal chemotherapy was performed in all these patients. The intraperitoneal chemotherapy protocols included： 5-FU 0.5-0.75 g/d for 10-15 consecutive days, with a total dosage of 5-12.5 g, and at the last day of chemotherapy 10 mg mitomycin （MMC） or 100 mg carboplatin was injected. For 7 cases of cholangiocarcinoma, Gemzar 800-1000 mg was administered additionally. A majority of all these patients received another one or two therapy methods followed by intraperitoneal chemotherapy. TACE was performed in the patients with multiple tumors or nodule more than 5 cm in diameter in the liver, RFA or PElT with nodule fewer than 4 in number and 5 cm or less than 5 cm in diameter and radiotherapy, only for metastases, with metastatic lymph nodes, localized metastasis within the abdominal cavity or portal vein embolus. Interval time between two methods was one month or so. Two months after the sequential therapy, repeated treatment would be given if general medical condition and liver function were perfect at that time. Results： The median survival time of the group was 13.97 ± 6.27 months. The 1- and 2-year survival rates were 59.7% and 30.6% respectively. The mean survival time of the patients with liver function Child A was 15.91 ± 5.49 months, and that of the patients with Child B was 8.55 ± 5.09 months. The difference was statistically significant （P 〈 0.05）. Conclusion： Intraperitoneal chemotherapy or in combination with other therapies in patients with advanced primary liver cancer with metastases to abdominal cavity is an effective method. It can prolong the survival time and improve life quality for a certain percentage of patients with advanced pnmary liver cancer.展开更多

METHODS： A total of 140 previously untreated cases of HCC were enrolled in this study from 1988 to 2002. The inclusion criteria were： a solitary tumor less than 4 cm in diameter or multiple tumors, fewer than four in number and less than 3 cm in diameter, without extrahepatic metastasis or vessel invasion. As general principles for the treatment of HCC, the patients underwent transcatheter arterial chemoembolization （TACE） prior to PEIT. After the initial treatment of the patients, ultrasonography and computed tomography were performed, and measurement of serum levels of α- fetoprotein （AFP） was determined. When tumor recurrences were detected, PEIT and/or TACE were repeated whenever the hepatic functional reserve of the patient permitted. We then analyzed the variables that could influence prognosis, including tumor size and number, the serum levels of AFP, the parameters of hepatic function （albumin, bilirubin, ALT, hepaplastin test, platelet number, and indocyanine green retention at 15 rain [ICG-R15]）, combined therapy with TACE, distant recurrence, and local recurrence. RESULTS： Univariate analysis identified the ICG test, serum levels of AFP and albumin, tumor size and number, and local recurrence, but not distant recurrence, as significant prognostic variables. In multivariate analysis using those five parameters, the ICG test, tumor size, tumor number, and local recurrence were identified as significant prognostic factors. In both univariate and multivariate analyses, the relative risk for the ICG test was the highest, followed by local recurrence. CONCLUSION： We found that local recurrence is an independent prognostic factor of HCC, indicating that achieving complete treatment for HCC on first treatment is important for improving the prognosis of patients with HCC. 2005 The WJG Press and Elsevier Inc.
