Clinical and Dosimetric Results of Proton or Photon Radiation Therapy for Large (>5 cm) Hepatocellular Carcinoma: A Retrospective Analysis. Int J Radiat Oncol Biol Phys 2024; 118:712-724. [PMID: 37778426 DOI: 10.1016/j.ijrobp.2023.09.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 09/07/2023] [Accepted: 09/21/2023] [Indexed: 10/03/2023]
Abstract
PURPOSE Our purpose was to report the clinical and dosimetric attributes of patients with large unresectable hepatocellular carcinoma (HCC) undergoing proton or photon radiation therapy. METHODS AND MATERIALS We retrospectively analyzed the outcomes and dosimetric indices of 159 patients with >5 cm nonmetastatic HCC who underwent definitive radiation therapy using either protons (N = 105) or photons (N = 54) between 2014 and 2018. Additional photon plans were performed in the 105 proton-treated patients using the same dose prescription criteria for intragroup dosimetric comparison. RESULTS After a median follow-up of 47 months, patients with biologically effective dose (BED10) ≥ 75 Gy exhibited significantly better local control (LC; 2-year: 85.6% vs 20.5%; P < .001), progression-free survival (PFS; median, 7.4 vs 3.2 months; P < .001), and overall survival (OS; median, 18.1 vs 7.3 months; P < .001) compared with those with BED10 < 75 Gy. Notably, proton-treated patients had a significantly higher BED10 (96 vs 67 Gy; P < .001) and improved LC (2-year: 88.5% vs 33.8%; P < .001), PFS (median, 7.4 vs 3.3 months; P = .001), and OS (median, 18.9 vs 8.3 months; P < .001) than those undergoing photon radiation therapy. Furthermore, patients treated with protons had significantly lower V1 of the liver (P < .001), mean upper gastrointestinal tract dose (P < .001), and mean splenic dose (P < .001), with significantly decreased incidences of radiation-induced liver disease (P = .007), grade ≥3 upper gastrointestinal bleeding (P = .001), and grade ≥3 lymphopenia (P = .003). On multivariate analysis, proton radiation therapy consistently correlated with superior LC (P < .001), PFS (P < .001), and OS (P < .001). In intragroup dosimetric comparison, photon plans demonstrated significantly higher mean liver dose (P < .001) compared with actually delivered proton treatments, and 72 (69%) of them had mean liver dose exceeding 28 Gy, which necessitated target dose de-escalation. CONCLUSIONS In the context of large HCC radiation therapy, a higher target BED10 was associated with improved outcomes. Notably, proton therapy has demonstrated the capability to deliver ablative doses while also being accompanied by fewer instances of severe toxicity.

Time variation of high-risk groups for liver function deteriorations within fluctuating long-term liver function after hepatic radiotherapy in patients with hepatocellular carcinoma. Eur J Med Res 2024; 29:104. [PMID: 38326881 PMCID: PMC10848403 DOI: 10.1186/s40001-024-01692-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 01/20/2024] [Indexed: 02/09/2024] Open
Abstract
PURPOSE The purpose of this study is to find essential risk factors associated with liver function (LF) deteriorations within fluctuating long-term LF and their time-varying effects in patients with hepatocellular carcinoma (HCC) receiving hepatic radiotherapy and to identify high-risk groups for adverse LF deteriorations and their changes over time in facilitating the prevention of hepatic decompensation and the improvement of survival. MATERIALS AND METHODS A total of 133 HCC patients treated by hepatic radiotherapy were enrolled. A study design was conducted to convert posttreatment long-term LF with fluctuating levels over time to recurrent LF events using defined upgrades in a grading scale. The hazard ratios (HR) of pretreatment biochemical, demographic, clinical, and dosimetric factors in developing posttreatment LF events were estimated using the Cox model. Methodologies of the counting process approach, robust variance estimation, goodness-of-fit testing based on the Schoenfeld residuals, and time-dependent covariates in survival analysis were employed to handle the correlation within subjects and evaluate the time-varying effects during long-term follow-up. RESULTS Baseline LF score before radiotherapy and gender were significant factors. Initial HR in developing LF events was 1.17 (95% CI 1.11-1.23; P < 0.001) for each increase of baseline LF score and kept almost constant over time (HR, 1.00; 95% CI 1.00-1.01; P = 0.065). However, no difference was observed regarding initial hazards for gender (HR, 1.00; 95% CI 0.64-1.56; P = 0.994), but the hazard for women got higher monthly over time compared with men (HR, 1.04; 95% CI 1.01-1.07; P = 0.006). CONCLUSIONS High-risk groups for adverse LF deteriorations after hepatic radiotherapy may change over time. Patients with poor baseline LF are vulnerable from the beginning. Women require prevention strategies and careful monitoring for deteriorations at a later stage.

Comparison of External Beam Radiation Therapy Modalities for Hepatocellular Carcinoma With Macrovascular Invasion: A Meta-Analysis and Systematic Review. Front Oncol 2022; 12:829708. [PMID: 35242713 PMCID: PMC8887617 DOI: 10.3389/fonc.2022.829708] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 01/24/2022] [Indexed: 12/12/2022] Open
Abstract
Purpose We performed a systematic review and meta-analysis to compare external beam radiation therapy modalities for hepatocellular carcinoma (HCC) with macrovascular invasion (MVI). Methods Studies were selected from online databases from the date of inception to November 2021. The outcomes of interest were overall survival (OS), objective response rate (ORR), and local control rate (LCR). Results Forty-four studies (n = 3730) were selected from 1050 articles. The pooled 1-year OS were 60.9%, 45.3%, and 44.9 for particle radiotherapy (PRT) group, conventional radiotherapy (CRT), and stereotactic body radiotherapy (SBRT) group, respectively; p = 0.005 and 0.002 for PRT vs. CRT and SBRT, respectively. Both the PRT group and the SBRT group have the advantage over the CRT group in the pooled ORR. The PRT group showed significantly higher than the CRT group (p = 0.007) in LCR. For combination therapy, CRT plus transarterial chemoembolization can prolong survival than CRT alone (p = 0.006 for 1-year OS; p = 0.014 for 2-year OS). Among grade ≥ 3 complications, the most frequent type of toxicity in CRT, SBRT, PRT group was hematological toxicity, hepatotoxicity, dermatological toxicity, respectively. Conclusions Among patients with HCC with MVI, the 1-year OS and the 2-year OS were both higher in the PRT group than in the CRT, SBRT groups. The ORR was similar between the PRT and SBRT groups. The combination therapy based on radiotherapy is expectable. PRT is associated with less complications than photon radiotherapy.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) is an aggressive tumor type which results in poor prognosis. ALBI and Child-Pugh score have been widely applied for predicting prognosis in patients with liver diseases. We conducted a systematic review to compare the prognostic ability of ALBI versus Child-Pugh in HCC patients. AREAS COVERED PubMed, EMBASE and Cochrane Library were explored. The data were extracted from every study. Studies investigating HCC patients and comparing the predicting ability between ALBI and Child-Pugh were analyzed. EXPERT OPINION This systematic review revealed that ALBI showed better discriminative ability than Child-Pugh for predicting the prognosis in HCC patients. However, the predictive abilities of two scores should be improved. Except for the most common used serum biomarker AFP for diagnosis and surveillance of HCC, recent studies have also explored all aspects of HCC through genome-wide sequencing, exome sequencing, RNA sequencing and genome-wide methylation analysis which provide essential clues for genotyping of HCC. Further studies should explore biomarkers by advanced techniques to validate new prognostic tools for early diagnosis and prognosis of HCC. Moreover, multicenter prospective studies should be carried out to compare the prognostic values of predictive indicators in HCC population in the future.

Yttrium-90 Radioembolization for BCLC Stage C Hepatocellular Carcinoma Comparing Child-Pugh A Versus B7 Patients: Are the Outcomes Equivalent? Cardiovasc Intervent Radiol 2020; 43:721-731. [PMID: 32140840 DOI: 10.1007/s00270-020-02434-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Accepted: 02/14/2020] [Indexed: 02/08/2023]
Abstract
OBJECTIVE To evaluate yttrium-90 (Y90) radioembolization outcomes across Child-Pugh scores in patients with advanced hepatocellular carcinoma (HCC). MATERIALS AND METHODS From April 2005 to December 2018, 106 consecutive patients with BCLC Stage C HCC who underwent Y90 radioembolization were retrospectively analyzed. Exclusion criteria included additional malignancy (n = 7), death unrelated to liver disease (n = 2), metastases (n = 2), or lack of follow-up data (n = 4). Ninety-one patients were analyzed. Overall survival (OS) was calculated using the Kaplan-Meier method and compared between groups with the log-rank test. Cox regression modeling was used to evaluate the prognostic factors for survival. RESULTS Mean age was 63 years and 85.7% were male. HCV infection was the most common etiology of liver disease (58.2%). Sixty-four (70.3%) patients were Child-Pugh A, 19 (20.9%) patients were B7, and eight (8.8%) patients were B8-9. Median OS after radioembolization was 20.2 [95% confidence interval (CI) 13.0-27.4], 6.0 (95% CI 4.4-7.6), and 5.5 (95% CI 2.5-8.5) months for Child-Pugh A, B7, and B8/9 groups, respectively (P < 0.001 for B7 vs. A; P = 0.537 for B7 vs. B8/9). The multivariable Cox regression analysis showed that Eastern Cooperative Oncology Group (ECOG) score (P < 0.001), Child-Pugh class (P = 0.005), tumor morphology pattern (P = 0.012), and Y90 delivery location (P = 0.020) were significant independent predictors of overall survival. CONCLUSIONS Outcomes from Y90 for BCLC C HCC for Child-Pugh B7 patients were equivalent to B8/9 patients and significantly worse compared to Child-Pugh A patients. Although further research is warranted, these results suggest continued cautious patient selection for radioembolization in advanced HCC.

Abstract
Hepatocellular carcinoma (HCC) has a high predilection with portal vein tumor thrombosis (PVTT). However, part of the PVTT type can be found only under the microscopy, which was namely as type I0. The objective of this study was to establish a simple and inexpensive non-invasive model to predict the presentation of PVTT at HCC patients. A total of 815 HCC patients were retrospectively evaluated and randomly assigned into 2 groups: the training group (n = 408) and validation group (n = 407). A new index model, namely WγAL, was built to predict the presence of PVTT in the training subjects and was further validated in the validation subjects. At the optimal cutoff of 8.90, WγAL identified patients with a hazard ratio (HR) of 7.139 for the presence of PVTT. The area under receiver operating characteristic (AUROC) of WγAL was 0.795 (sensitivity: 71.9%; specificity: 78.6%) for differentiation between PVTT and non-PVTT patients in the training group. The AUROC of WγAL in differentiating patients with PVTT type I0 from non-PVTT patients was 0.748 (sensitivity: 72.1%; specificity: 68.4%) with an HR of 5.355. In addition, WγAL > 8.90 was significantly associated with large tumors, multiple tumor numbers, TNM stage III-IV, metastasis, and overall survival in HCC patients. The novel predictive model represents a simple and inexpensive model that can identify the presence of PVTT in HCC patients with a high degree of accuracy, with important clinical significance in the future therapeutic management of HCC patients.
