- W2013864453 abstract "The impact of the use of preoperative portal vein embolization (PVE) on long-term survival after surgery was evaluated by retrospective analysis of prognostic factors in patients with advanced-stage hepatocellular carcinoma (HCC) who had undergone hepatic resection with or without PVE.The portal embolization group (Group P) consisted of 26 patients who had undergone major hepatectomy (more extensive than right hepatectomy) with PVE, and the nonembolized group (Group N) consisted of 43 patients who had undergone major hepatectomy without PVE. All patients were diagnosed with advanced HCC graded as Stage III or IV according to the International Union Against Cancer TNM classification system. Patient survival rates, recurrence rates, and recurrence sites after surgery in the two groups were evaluated and compared.The 1-year, 3-year, and 5-year cumulative disease specific survival rates in patients with TNM Stage III HCC, respectively, were 96.0%, 64.4%, and 52.7% in Group N and 92.9%, 57.1%, and 45.7% in Group P, whereas the corresponding values in patients with Stage IV HCC were 53.5%, 40.1%, and 26.8% in Group N and 63.5%, 50.8%, and 19.1% in Group P. There were no statistically significant differences in survival rates between Group P and Group N. Multivariate analysis showed that PVE was not a significant prognostic factor. The 1-year, 3-year, and 5-year cumulative recurrence rates for patients with both stages of disease combined were 44.1%, 80.2%, and 86.8% in Group N, respectively, and 39.9%, 72.2%, and 72.2% in Group P, respectively, with no statistically significant differences between the two groups. To date, 35 patients in Group N and 16 patients in Group P have had tumor recurrences in the liver remnant; of these, 27 patients in Group N and 12 patients in Group P had multiple recurrence foci in the liver remnant. No significant difference was seen between the two groups; however, 10 of 16 patients in Group P (62.5%) had remote organ metastasis in addition to recurrence in the liver remnant compared with only 6 of 35 patients in Group N (17.1%): This difference was significant statistically (P = 0.012).PVE during major hepatic resection neither improves nor worsens long-term prognosis but allows resection in a patient group that, otherwise, is considered as unresectable. Remote metastasis involving the lung, bone, or stomach was seen more frequently postoperatively in Group P compared with Group N, raising a possibly important issue regarding the use of this approach for the treatment of patients with hepatic malignancies, especially HCC." @default.
