Hepatocellular carcinoma (HCC) is the second most common cancer in Taiwan and transcatheter arterial chemoembolization (TACE) is now the mainstay of treatment for noncurative HCC. Due to increasing medical costs yearly and financial problem of the Bureau of National Health Insurance, it is important to reduce medical resource utilization including hospital stay and medical costs. The aim is to figure out the risk factors of extended hospital stay, and increased in-hospital medical costs in hepatocellular carcinoma patients receiving transcatheter arterial chemoembolization. The result of this study should be available for further improvement of medical care quality in the limited medical resource. From January 2008 to January 2010, 162 patients (121 male and 41 female) with histologically proven hepatocellular carcinoma underwent TACE only (131 pts) or TACE followed by catheter placement for hepatic artery infusion chemotherapy (HAIC) (31pts) at district teaching hospital. The extended hospital stay (EHS) and extended post-procedure stay (EPS) are defined as stay larger than their median values (11 & 7 days respectively). Clinical demographic, disease factors, tumor factors, procedure (TACE)-related factors and complications are used to identify the univariate factors related to EHS and EPS statistically. To find out predictors of EHS, EPS and increased in-hospital medical costs, multiple linear regression analyses are used. The risk factors for EPS are procedure-related, including complications and procedure methods ( TACE + HAIC related to TACE only) (R2=.367, p<.001), while those for EHS are complications, encephalopathy, procedure methods, Child-Pugh classification C (related to classification A) and age (R2=.490, p<.001). The predictors for increased in-hospital medical costs include procedure methods, AJCC stage IV, T4 stage, hepatoencephalopathy and complications (R2=0.615, p<.001). Taking total hospital stay into consideration, the most important risk factor related to increased medical cost is total hosptial stay itself. The most powerful risk factor for EPS, EHS is procedure-related complication. The different procedure methods also affect hospital stay and medical costs. In order to reduce medical resource utilization, we should avoid post-procedure complication and pay attention to cirrhotic degree as well as American Joint Committee of Cancer (AJCC) tumor stage system. The result of this study can provide some ideas to adjust medical expense polices for the Bureau of National Health Insurance and to control medical cost for the hospitals.

Purpose: To evaluate the efficiency of a multimodality approach consisting of transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) as bridging therapy for patients with hepatocellular carcinoma (HCC) awaiting orthotopic liver transplantation (OLT) and to evaluate the histopathological response in explant specimens. Materials and Methods: Between April 2001 and November 2011, 36 patients with 50 HCC nodules (1.4–5.0 cm, median 2.8 cm) on the waiting list for liver transplantation were treated by TACE and RFA. The drop-out rate during the follow-up period was recorded. The local efficacy was evaluated by histopathological examination of the explanted livers. Results: During a median follow-up time of 29 (4.0–95.3) months the cumulative drop-out rate for the patients on the waiting list was 0, 2.8, 5.5, 11.0, 13.9 and 16.7% at 3, 6, 12, 24, 36 and 48 months, respectively. 16 patients (with 26 HCC lesions) out of 36 (44.4%) were transplanted by the end of study with a median waiting list time of 13.7 (2.5–37.8) months. The histopathological examination of the explanted specimens revealed a complete necrosis in 20 of 26 HCCs (76.9%), whereas 6 (23.1%) nodules showed viable residual tumor tissue. All transplanted patients are alive at a median time of 29.9 months. Imaging correlation showed 100% specificity and 66.7% sensitivity for the depiction of residual or recurrent tumor. Conclusion: We conclude that TACE combined with RFA could provide an effective treatment to decrease the drop-out rate from the OLT waiting list for HCC patients. Furthermore, this combination therapy results in high rates of complete tumor necrosis as evaluated in the histopathological analysis of the explanted livers. Further randomized trials are needed to demonstrate if there is a benefit in comparison with a single-treatment approach. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
