We studied the relation of perioperative blood transfusion and the outcomes in 175 patients with hepatocellular carcinoma (HCC) who underwent hepatic resection from 1986 to 1994 in our hospital. Hepatectomy was performed in 23 (13.1%) patients with and 152 (86. 9%) without blood transfusions. The cumulative cancer-free survival rates for patients who had received blood transfusion was significantly lower than that for patients who had not received blood transfusions (p = 0.003). Further examinations revealed a significant difference in cancer-free survival rates for stage I-II patients (n = 75) of HCC (p = 0.02) but not for stage III-IV patients (n = 56) (p = 0.06). Cox regression analysis for recurrence revealed that blood transfusion was the most significant prognostic indicator (p = 0.001) for recurrence in stage I-II patients but not in stage III-IV patients (p = 0.99). These results suggest that a perioperative blood transfusion may be a significant prognostic indicator for patients with HCC who had underwent hepatectomy, especially in stage I-II patients of HCC.

The combination of radiofrequency ablation and transcatheter arterial chemoembolization using doxorubicin markedly increased the extent of induced coagulation compared with radiofrequency alone, despite a small number of patients and the preliminary nature of this study.

BackgroundRenal cell carcinoma is well-known for its propensity to metastasize to unusual sites. However, metastasis to the gallbladder has been rarely reported in the literature.Case presentationA 75-year-old Japanese (Asian) woman presented for further evaluation of a gallbladder polyp, 15 years after right radical nephrectomy for renal cell carcinoma. Computed tomography revealed a 12 mm enhancing pedunculated tumor in the gallbladder fundus. Open simple cholecystectomy was performed and the tumor was histologically confirmed as a metastasis of renal cell carcinoma to the gallbladder. Our patient is alive and has been disease-free for 3 years after cholecystectomy.ConclusionsAlthough metastasis of renal cell carcinoma is a rare differential diagnosis of gallbladder tumors, simple cholecystectomy is likely to offer a chance of long-term survival for patients with gallbladder metastases of renal cell carcinoma.
