A model predicting survival of patients with recurrent or progressive hepatocellular carcinoma: the MORE score

Liver resection for large and huge hepatocellular carcinoma: Predictors of failure, recurrence patterns, and prognoses

BACKGROUND

Characteristic symptoms and signs are often absent in patients with hepatocellular carcinoma (HCC). As a result, many patients are not diagnosed until their tumors have grown to large (> 5cm) or huge sizes (> 10cm). Liver resection has traditionally been reserved for patients with small HCC, but more recently it is being used for patients with large and huge tumors. The aim of this study was to determine risk predictors of recurrence, patterns of recurrence, and survival rates for large and huge HCC patients who underwent curative liver resection.

MATERIALS AND METHODS

We retrospectively identified a subgroup of patients who underwent liver resection for HCC with diameters 5 cm or larger. Overall survival (OS) and recurrence-free survival (RFS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to investigate potential risk factors for recurrence and death.

RESULTS

Among 897 patients, the median follow-up was 48 (range, 5-140) months. The 1-, 3-, and 5-year RFS rates were 51.6%, 36.1%, and 30.1%, respectively, and OS rates were 80.2%, 55.4%, and 47.7%, respectively. Significant independent predictors of recurrence were preoperative satellite nodule (HR = 2.25; 95% CI, 1.17-4.31; p = .02), preoperative AFP levels above 400 ng/ml (HR = 1.23; 95% CI, 1.04-1.45; p = .01), resection margins of 1 cm or less (HR = 1.21; 95% CI, 1.00-1.46; p = .047), cirrhosis (HR = 2.64; 95% CI, 2.13-3.28; p < .001), and microvascular invasion (HR = 1.71; 95% CI, 1.45-2.20; p < .001). All of these except narrow resection margin were also independent risk factors of OS.

CONCLUSIONS

Hepatic resection for patients with large and huge HCC without hepatic vascular invasion, extrahepatic metastases, or severe chronic liver disease results in acceptable long-term outcomes.

Predicting outcomes for recurrent hepatocellular carcinoma within Milan criteria after complete radiofrequency ablation

BACKGROUND

Intrahepatic distant recurrence (IDR) is a significant problem for patients who have undergone radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). The objective of the study was to investigate risk factors and to predict outcomes of recurrent IDR within Milan criteria after complete RFA for primary early-stage HCC.

METHOD

This retrospective study reviewed 449 patients with intrahepatic distant recurrent HCC after complete RFA for early-stage HCC. After excluding 100 patients who were beyond Milan criteria, with incomplete lab data, or had follow-up less than three months, a total of 349 patient cases were compiled and their baseline characteristics, further treatment modalities after tumor recurrence and survival were analyzed.

RESULTS

After a median follow-up of 36.2 months, 92 patients had expired. The majority of patients were male (59.9%) with a median age of 64.3 years (range:38-88). The cumulative 5-year overall survival (OS) rates after treatment for recurrent HCC was 67.2%. On multivariate analysis, end-stage renal disease(Hazard ratio (H.R.) = 2.33, p = 0.021), m-ALBI grade 2a (H.R. = 2.86, p = 0.003) and m-ALBI grades 2b or 3 (H.R. = 2.30, p = 0.009), APRI greater than 1 (H.R. = 1.92, p = 0.036) and 2nd recurrence occurring within 1 year (H.R. = 2.69, p<0.001) were significantly associated with worse survival. The cumulative 5-year 2nd recurrence rate was 87.4%. On multivariate analysis, male gender (H.R. = 1.47, p = 0.01), age greater than 65 years (H.R. = 1.72, p<0.001), an alpha fetoprotein level greater than 20ng/ml (H.R. = 1.41, p = 0.016), surgical treatment for recurrent HCC (H.R. = 0.25, p = 0.007), tumor number greater than 1 (H.R. = 1.35, p = 0.046), and IDR developing within 2 years (H.R. = 1.67, p = 0.001) were prognostic factors for 2nd recurrence.

CONCLUSION

Our study suggested that presence of end-stage renal disease, m-ALBI grades 2 and 3, APRI >1 and time to 2nd HCC recurrence were all associated with overall survival while the 2nd HCC recurrence was associated with male gender, age ≥65 years, α-fetoprotein level >20 ng/mL, non-surgical therapy, time to IDR, and tumor number> 1.

All-treatment array of hepatocellular carcinoma from initial diagnosis to death: observation of cumulative treatments

PURPOSE

In clinical practice, most patients with hepatocellular carcinoma require subsequent treatments for remaining, progressing, or recurring tumors. We investigated all-treatment array and outcomes in an HCC cohort from initial diagnosis to death.

METHODS

We enrolled 1687 consecutive patients with HCC who underwent initial diagnosis and treatment at the National Cancer Center, Korea, from January 2004 to December 2009.

RESULTS

In total, 1357 patients (80.4%) showed RPRTs during median 20.4-month follow-up. Initial transplantation resulted in the least rate (32.3%) of RPRTs. Median treatment frequency was 3.0 times (range 1-20) and 382 patients (27.3%) received treatments ≥6 times. The median treatment frequency was different based on four factors (p < 0.05): age, tumor stage, tumor type and initial treatment modality. Patients with Barcelona Clinic Liver Cancer stage 0 received less frequent treatments. As the stage progressed from 0 to B, the median treatment frequency increased. Radiofrequency ablation as initial treatment was associated with the longest median treatment interval at 19.0 weeks, followed by resection at 14.1 weeks. The median treatment interval was significantly shorter as the stage progressed (p < 0.01). TACE was most frequently performed for RPRTs; the median number of subsequent TACE was 3 (range 1-19). Subsequent treatment array was very heterogeneous, and no certain pattern was found.

CONCLUSIONS

Our findings suggest that the survival outcome of patients with HCC is based on the results of cumulative multiple treatments rather than an initial treatment. It is time to consider prospective studies evaluating sequential treatment array of HCC.
