A differential risk assessment and decision model for Transarterial chemoembolization in hepatocellular carcinoma based on hepatic function.

BACKGROUND: The decision of transarterial chemoembolization (TACE) initiation and/or repetition remains challenging in patients with unresectable hepatocellular carcinoma (HCC). The aim was to develop a prognostic scoring system to guide TACE initiation/repetition. METHODS: A total of 597 consecutive patients who underwent TACE as their initial treatment for unresectable HCC were included. We derived a prediction model using independent risk factors for overall survival (OS), which was externally validated in an independent cohort (n = 739). RESULTS: Independent risk factors of OS included Albumin-bilirubin (ALBI) grade, maximal tumor size, alpha-fetoprotein, and tumor response to initial TACE, which were used to develop a scoring system ("ASAR"). C-index values for OS were 0.733 (95% confidence interval [CI] = 0.570-0.871) in the derivation, 0.700 (95% CI = 0.445-0.905) in the internal validation, and 0.680 (95% CI = 0.652-0.707) in the external validation, respectively. Patients with ASAR< 4 showed significantly longer OS than patients with ASAR≥4 in all three datasets (all P < 0.001). Among Child-Pugh class B patients, a modified model without TACE response, i.e., "ASA(R)", discriminated OS with a c-index of 0.788 (95% CI, 0.703-0.876) in the derivation, and 0.745 (95% CI, 0.646-0.862) in the internal validation, and 0.670 (95% CI, 0.605-0.725) in the external validation, respectively. Child-Pugh B patients with ASA(R) < 4 showed significantly longer OS than patients with ASA(R) ≥ 4 in all three datasets (all P < 0.001). CONCLUSIONS: ASAR provides refined prognostication for repetition of TACE in patients with unresectable HCC. For Child-Pugh class B patients, a modified model with baseline factors might guide TACE initiation.

Assessment of the Surveillance Interval at 1 Year after Curative Treatment in Hepatocellular Carcinoma: Risk Stratification.

Background/Aims: Guidelines recommend surveillance for hepatocellular carcinoma (HCC) recurrence at 3-month intervals during the first year after curative treatment and 6-month intervals thereafter in all patients. This strategy does not reflect individual risk of recurrence. We aimed to stratify risk of recurrence to optimize surveillance intervals 1 year after treatment. Methods: We retrospectively analyzed 1,316 HCC patients treated with resection/radiofrequency ablation at Barcelona Clinic Liver Cancer stage 0/A. In patients without 1-year recurrence under 3-monthly surveillance, a new model for recurrence was developed using backward elimination methods: training (n=582)/validation cohorts (n=291). Overall survival (OS) according to risk stratified by the new model was compared according to surveillance intervals: 3-monthly versus 6-monthly (n=401) after lead time bias correction and propensity-score matching analyses. Results: Among patients without 1-year recurrence, age and international normalized ratio values were significant factors for recurrence (hazard ratio [HR], 1.03; 95% confidence interval [CI], 1.00 to 1.03; p=0.009 and HR, 5.63; 95% CI, 2.24 to 14.18; p<0.001; respectively). High-risk patients stratified by the new model showed significantly higher recurrence rates than low-risk patients in the validation cohort (HR, 1.73; 95% CI, 1.18 to 2.53; p=0.005). After propensity-score matching between the 3-monthly and 6-monthly surveillance groups, OS in high-risk patients under 3-monthly surveillance was significantly higher than that under 6-monthly surveillance (p=0.04); however, OS in low-risk patients under 3-monthly surveillance was not significantly different from that under 6-monthly surveillance (p=0.17). Conclusions: In high-risk patients, 3-monthly surveillance can prolong survival compared to 6-monthly surveillance. However, in low-risk patients, 3-monthly surveillance might not be beneficial for survival compared to 6-monthly surveillance.

Perceived needs for the information communication technology (ICT)-based personalized health management program, and its association with information provision, health-related quality of life (HRQOL), and decisional conflict in cancer patients.

OBJECTIVE: The use of information communication technology (ICT)-based tailored health management program can have significant health impacts for cancer patients. Information provision, health-related quality of life (HRQOL), and decision conflicts were analyzed for their relationship with need for an ICT-based personalized health management program in Korean cancer survivors. METHODS: The health program needs of 625 cancer survivors from two Korean hospitals were analyzed in this cross-sectional study. Multivariate logistic regression was used to identify factors related to the need for an ICT-based tailored health management system. Association of the highest such need with medical information experience, HRQOL, and decision conflicts was determined. Furthermore, patient intentions and expectations for a web- or smartphone-based tailored health management program were investigated. RESULTS: Cancer survivors indicated high personalized health management program needs. Patients reporting the highest need included those with higher income (adjusted odds ratio [aOR], 1.70; 95% [confidence interval] CI, 1.10-2.63), those who had received enough information regarding helping themselves (aOR, 1.71; 95% CI, 1.09-2.66), and those who wished to receive more information (aOR, 1.59; 95% CI, 0.97-2.61). Participants with cognitive functioning problems (aOR, 2.87; 95%CI, 1.34-6.17) or appetite loss (aOR, 1.77; 95% CI, 1.07-2.93) indicated need for a tailored health care program. Patients who perceived greater support from the decision-making process also showed the highest need for an ICT-based program (aOR, 0.49; 95% CI, 0.30-0.82). CONCLUSIONS: We found that higher income, information provision experience, problematic HRQOL, and decisional conflicts are significantly associated with the need for an ICT-based tailored self-management program.

Prognostic stratification of brain metastases from hepatocellular carcinoma.

The aim of this study is to evaluate prognostic factors of brain metastases from hepatocellular carcinoma. Medical records of 95 patients who have been diagnosed of brain metastases from hepatocellular carcinoma between January 2000 and December 2011 were retrospectively reviewed. The median age at diagnosis of brain metastases is 56.1 years. Eighty-two patients were male. Median interval from diagnosis of hepatocellular carcinoma to brain metastases was 29.5 months. Eighty-eight patents had extracranial metastases, and the lung was the most frequent involved organ. Motor weakness was the most frequent presenting symptom (49.5%). Intracranial hemorrhage was present in 71 patients (74.7%). Brain metastases were treated with whole brain radiation therapy (WBRT) alone in 57 patients, radiosurgery alone in 18, surgery and WBRT in 6, surgery and radiosurgery in 3, surgery alone in 3, radiosurgery and WBRT in 2, and conservative management only in 6. Median overall survival was 3.0 months. Multivariate analysis showed ECOG performance status, Child-Pugh class, AFP level, number of brain lesions, and treatment modality were associated with survival (p < 0.05). When patients were stratified with four prognostic factors including ECOG performance status, Child-Pugh class, AFP level, and number of brain lesions, median survival time for patients with 0-1, 2, 3-4 risk factors were 5.8 months, 2.5 months and 0.6 months, respectively (p < 0.001). In conclusion, we can estimate the survival of patients by prognostic stratification, although overall prognosis of patients with brain metastases from hepatocellular carcinoma is poor.
