RESUMEN
BACKGROUND: To improve the prognosis of advanced intrahepatic cholangiocarcinoma (iCCA), we retrospectively compared the effect and safety of combined hepatic arterial infusion chemotherapy (HAIC), targeted therapy and immunotherapy with systemic chemotherapy (SC) in unresectable iCCA patients. METHODS: We retrospectively enrolled 202 advanced iCCA patients treated with SC or targeted therapy, immunotherapy, and FOLFOX-HAIC combined between March 2015 and June 2023 at our institution. 202 patients were divided into two groups based on the therapeutic regimens. Baseline characteristics and prognosis were reviewed and analyzed. RESULTS: After 1-to-1 propensity score matching, 76 patients were included in each group. The triple combination therapy group demonstrated longer median overall survival (OS, 20.77 vs. 14.83 months, P=0.047), progression-free survival (PFS, 9.07 vs. 6.23 mo, P<0.001), intrahepatic PFS (11.03 vs. 6.73 mo, P<0.001), extrahepatic PFS (11.37 vs. 7.13 months, P=0.0064), and a higher objective response rate (35.5% vs. 14.5%, P=0.003) than the SC group. Fever, thrombocytopenia, elevated ALT, elevated AST, hypoalbuminemia, and hyperbilirubinemia were more common adverse events (AEs) in the triple combination therapy group, while fatigue and anemia were more prevalent in the SC group (P<0.05). For grades 3-4 AEs, the rates of elevated ALT were higher in the triple combination group (P=0.028). CONCLUSIONS: Compared with SC, triple combination therapy comprising HAIC, targeted therapy and immunotherapy appears to be an effective and safe treatment for advanced iCCA.
RESUMEN
BACKGROUND: Few studies have focused on the efficacy of stereotactic body radiation therapy (SBRT) in treating early hepatocellular carcinoma (HCC) for curative intention. This study aims to determine the best option among resection, ablation and SBRT in dealing with single HCC no more than 5 cm. MATERIALS AND METHODS: This multicenter retrospective cohort study included 985 patients from 3 hospitals: 495, 335 and 155 in the resection, ablation and SBRT groups, respectively between January 2014 and December 2021. Subgroup analysis and propensity score matching (PSM) were performed. RESULTS: The SBRT group had unfavorable clinical features including larger tumor size, poorer liver function and more relapsed tumors. The 1-, 3-, and 5-year recurrence free survival (RFS) rates were 84.3%, 66.8% and 56.2% with resection, 73.3%, 49.8% and 37.2% with ablation and 73.2%, 56.4% and 53.6% with SBRT, respectively (P<0.001). The 3-year overall survival (OS) rates were 89.0%, 89.2% and 88.8% in the resection, ablation and SBRT group, respectively (P=0.590). The three modalities resulted in similar RFS and OS after adjusting for clinical factors. Resection provided ideal local tumor control, successively followed by SBRT and ablation. SBRT led to comparable RFS time compared to resection for tumors < 3 cm (HR=0.75, P=0.205), relapsed tumors (HR=0.83, P=0.420) and patients with poor liver function (HR=0.70, P=0.330). In addition, SBRT was superior to ablation regarding RFS when tumors were adjacent to intra-hepatic vessels (HR=0.64, P=0.031). SBRT were more minimally invasive, however, gastrointestinal disorders, hepatic inflammation and myelosuppression occurred more frequently. CONCLUSION: All three approaches could be applied as curative options. Resection remains the best choice for preventing tumor recurrence, and SBRT showed advantages in treating small, recurrent and vascular-type lesions as well as patients with relatively poor liver function.
RESUMEN
Circular RNAs (circRNAs) are covalently closed, single-stranded RNAs that play critical roles in various biological processes and diseases, including cancers. However, the functions and mechanisms of circRNAs in hepatocellular carcinoma (HCC) need further clarification. Here, we identified and confirmed that circATF6 is downregulated in HCC tissues and negatively associated with the overall survival of HCC patients. Ectopic overexpression of circATF6 inhibits malignant phenotypes of HCC cells in vitro and in vivo, while knockdown of circATF6 had opposite effects. Mechanistically, we found that circATF6 bound to calreticulin (CALR) protein and acted as a scaffold to enhance the interaction of CALR with calpain2 (CAPN2), which promoted the degradation of CALR by its enzymatic activity. Moreover, we found that circATF6 inhibited HCC cells by suppressing CALR-mediated wnt/ß-catenin signaling pathway. Taken together, our findings suggest that circATF6 is a potential prognostic biomarker and therapeutic target for HCC.
RESUMEN
Importance: Transarterial chemoembolization (TACE) is commonly used to treat patients with recurrent intermediate-stage hepatocellular carcinoma (HCC) and positive microvascular invasion (MVI); however, TACE alone has demonstrated unsatisfactory survival benefits. A previous retrospective study suggested that TACE plus sorafenib (SOR-TACE) may be a better therapeutic option compared with TACE alone. Objective: To investigate the clinical outcomes of SOR-TACE vs TACE alone for patients with recurrent intermediate-stage HCC after R0 hepatectomy with positive MVI. Design, Setting, and Participants: In this phase 3, open-label, multicenter randomized clinical trial, patients with recurrent intermediate-stage HCC and positive MVI were randomly assigned in a 1:1 ratio via a computerized minimization technique to either SOR-TACE treatment or TACE alone. This trial was conducted at 5 hospitals in China, and enrolled patients from October 2019 to December 2021, with a follow-up period of 24 months. Data were analyzed from June 2023 to September 2023. Interventions: Randomization to on-demand TACE (conventional TACE: doxorubicin, 50 mg, mixed with lipiodol and gelatin sponge particles [diameter: 150-350 µm]; drug-eluting bead TACE: doxorubicin, 75 mg, mixed with drug-eluting particles [diameter: 100-300 µm or 300-500 µm]) (TACE group) or sorafenib, 400 mg, twice daily plus on-demand TACE (SOR-TACE group) (conventional TACE: doxorubicin, 50 mg, mixed with lipiodol and gelatin sponge particles [diameter, 150-350 µm]; drug-eluting bead TACE: doxorubicin, 75 mg, mixed with drug-eluting particles [diameter: 100-300 µm or 300-500 µm]). Main Outcomes and Measures: The primary end point was overall survival by intention-to-treat analysis. Safety was assessed in patients who received at least 1 dose of study treatment. Results: A total of 162 patients (median [range] age, 55 [28-75] years; 151 males [93.2%]), were randomly assigned to be treated with either SOR-TACE (n = 81) or TACE alone (n = 81). The median overall survival was significantly longer in the SOR-TACE group than in the TACE group (22.2 months vs 15.1 months; hazard ratio [HR], 0.55; P < .001). SOR-TACE also prolonged progression-free survival (16.2 months vs 11.8 months; HR, 0.54; P < .001), and improved the objective response rate when compared with TACE alone based on the modified Response Evaluation Criteria in Solid Tumors criteria (80.2% vs 58.0%; P = .002). Any grade adverse events were more common in the SOR-TACE group, but all adverse events responded well to treatment. No unexpected adverse events or treatment-related deaths occurred in this study. Conclusions and Relevance: The results of this randomized clinical trial demonstrated that SOR-TACE achieved better clinical outcomes than TACE alone. These findings suggest that combined treatment should be used for patients with recurrent intermediate-stage HCC after R0 hepatectomy with positive MVI. Trial Registration: ClinicalTrials.gov Identifier: NCT04103398.

BACKGROUND: Alpha-fetoprotein (AFP) has been established as a biomarker for hepatocellular carcinoma (HCC); however, whether its dynamic changes could predict the response to systemic therapy remains elusive. This study explored the AFP trajectory and the association with survival in patients received bevacizumab plus immunotherapy. METHODS: We retrospectively enrolled 536 HCC patients received bevacizumab plus immunotherapy between February 2021 and February 2023. Patients were divided into two groups according to AFP values before treatment (400 ng/ml). Dynamic changes of AFP were fitted using a latent class model to generate the AFP trajectories. Multivariable Cox models were utilized to compute hazard ratios (HRs) for survival. Inverse-probability-of-treatment weighted analyses were conducted to mitigate the influence of unmeasured confounding variables. The primary endpoint is progression free survival (PFS). The second endpoint is overall survival (OS). RESULTS: Three distinct trajectories were identified for AFP-low and AFP-high patients, respectively. In AFP-low group, compared with the high-rising class (25%; n=69), HRs of PFS were 0.39 and 0.2 for the low-stable class (59.1%; n=163) and sharp-falling class (15.9%; n=44), after adjusting by tumor diameter, tumor number, and extra-hepatic metastasis. In AFP-high group, compared with the high-stable class (18.5%; n=48), HRs of PFS were 0.3 and 0.04 for the middle-stable class (56.5%; n=147) and sharp-falling class (25%; n=65), after adjusting by tumor diameter, tumor number, and extra-hepatic metastasis. Furthermore, the AFP trajectories exhibited the utmost relative importance among all covariates regarding PFS and OS in the multivariable regression models. CONCLUSION: The AFP trajectories in HCC patients receiving bevacizumab and immunotherapy, constituted an independent biomarker indicative of clinical outcomes. Findings from this study hold potential clinical utility in dynamically forecasting the prognosis of systemic therapy in HCC patients and facilitating clinical decision-making. Rapid reduction of AFP post-treatment can lead to favorable patient prognoses.
RESUMEN
BACKGROUND: Little is known about the role of vitamin D receptor polymorphisms and their interaction with vitamin D status in hepatocellular carcinoma (HCC) prognosis. METHODS: We evaluated the association of TaqI, BsmI, Cdx-2, and ApaI polymorphisms, individually and in combination, with liver cancer-specific (LCSS) and overall survival (OS) among 967 patients with newly diagnosed HCC. Subsequently, we examined whether these polymorphisms modified the association between serum bioavailable 25-hydroxyvitamin D (25OHD) concentrations and survival. Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: During a median follow-up of 1017 days, 393 deaths occurred, with 360 attributed to HCC. Having TaqI G allele (HRper allele = 1.30, 95% CI = 1.08 to 1.57) or BsmI T allele (HRper allele = 1.41, 95% CI = 1.01 to 1.99) was associated with worse LCSS. Carrying increasing numbers of protective alleles was associated with superior LCSS (HR6-8 vs 0-3 = 0.52, 95% CI = 0.34 to 0.80). The inverse association of bioavailable 25OHD with LCSS was only significant in patients with TaqI AA (HRQuartile 4 vs Quartile 1 = 0.63, 95% CI = 0.44 to 0.92), BsmI CC (HRQuartile 4 vs Quartile 1 = 0.62, 95% CI = 0.44 to 0.88), and 6 to 8 protective alleles (HRQuartile 4 vs Quartile 1 = 0.45, 95% CI = 0.23 to 0.87). Similar associations were observed for OS. CONCLUSIONS: Patients carrying wild-type TaqI, BsmI, or more protective alleles had improved survival and might benefit from optimizing bioavailable 25OHD status.
RESUMEN
Metabolic changes play a crucial role in determining the status and function of macrophages, but how lipid reprogramming in macrophages contributes to tumor progression is not yet fully understood. Here, we investigated the phenotype, contribution, and regulatory mechanisms of lipid droplet (LD)-laden macrophages (LLMs) in hepatocellular carcinoma (HCC). Enriched LLMs were found in tumor tissues and were associated with disease progression in HCC patients. The LLMs displayed immunosuppressive phenotypes (with extensive expression of TREM2, PD-L1, CD206, and CD163) and attenuated the antitumor activities of CD8+ T cells. Mechanistically, tumor-induced reshuffling of cellular lipids and TNFα-mediated uptake of tumoral fatty acids contribute to the generation of triglycerides and LDs in macrophages. LDs prolong LLM survival and promote CCL20 secretion, which further recruits CCR6+ Tregs to HCC tissue. Inhibiting LLM formation by targeting DGAT1 and DGAT2, which catalyze the synthesis of triglycerides, significantly reduced Treg recruitment, and delayed tumor growth in a mouse hepatic tumor model. Our results reveal the suppressive phenotypes and mechanisms of LLM enrichment in HCC and suggest the therapeutic potential of targeting LLMs for HCC patients.
RESUMEN
Ubiquitin-proteasome system dysfunction triggers α-synuclein aggregation, a hallmark of neurodegenerative diseases, such as Parkinson's disease (PD). However, the crosstalk between deubiquitinating enzyme (DUBs) and α-synuclein pathology remains unclear. In this study, we observed a decrease in the level of ubiquitin-specific protease 14 (USP14), a DUB, in the cerebrospinal fluid (CSF) of PD patients, particularly females. Moreover, CSF USP14 exhibited a dual correlation with α-synuclein in male and female PD patients. To investigate the impact of USP14 deficiency, we crossed USP14 heterozygous mouse (USP14+/-) with transgenic A53T PD mouse (A53T-Tg) or injected adeno-associated virus (AAV) carrying human α-synuclein (AAV-hα-Syn) in USP14+/- mice. We found that Usp14 deficiency improved the behavioral abnormities and pathological α-synuclein deposition in female A53T-Tg or AAV-hα-Syn mice. Additionally, Usp14 inactivation attenuates the pro-inflammatory response in female AAV-hα-Syn mice, whereas Usp14 inactivation demonstrated opposite effects in male AAV-hα-Syn mice. Mechanistically, the heterodimeric protein S100A8/A9 may be the downstream target of Usp14 deficiency in female mouse models of α-synucleinopathies. Furthermore, upregulated S100A8/A9 was responsible for α-synuclein degradation by autophagy and the suppression of the pro-inflammatory response in microglia after Usp14 knockdown. Consequently, our study suggests that USP14 could serve as a novel therapeutic target in PD.

BACKGROUND: Lenvatinib is widely used in treatment of unresectable hepatocellular carcinoma (uHCC), but the benefit of its combination with immunotherapy needs to be verified. This study evaluated the efficacy and safety of tislelizumab plus lenvatinib in systemic treatment-naïve patients with uHCC. METHODS: In this multicenter, single-arm, phase 2 study, systemic treatment-naïve patients with uHCC received tislelizumab 200 mg every three weeks plus lenvatinib (bodyweight ≥ 60 kg: 12 mg; < 60 kg: 8 mg; once daily). Dose-limiting toxicities (DLTs) were evaluated in safety run-in phase to determine whether to enter the expansion phase. The primary endpoint was objective response rate (ORR) assessed by independent review committee (IRC) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1). Based on Simon's two-stage design, > 6 responders were needed in stage 1 (n = 30) to continue the study, and ≥ 18 responders were needed by the end of stage 2 (n = 60) to demonstrate statistical superiority to a historical control of lenvatinib monotherapy. RESULTS: Sixty-four patients were enrolled. No DLTs were reported. The study achieved statistical superiority (p = 0.0003) with 23 responders assessed by IRC per RECIST v1.1 in the first 60 patients of the efficacy evaluable analysis set (n = 62). After a median follow-up of 15.7 months, confirmed ORR and disease control rate were 38.7% (24/62, 95% confidence interval [CI], 26.6-51.9) and 90.3% (56/62, 95% CI, 80.1-96.4), respectively. Median progression-free survival was 8.2 months (95% CI, 6.8-not evaluable). Overall survival rate at 12 months was 88.6% (95% CI, 77.7-94.4). Grade ≥ 3 treatment-related adverse events occurred in 18 (28.1%) patients. CONCLUSIONS: Tislelizumab plus lenvatinib demonstrated promising antitumor activity with favourable tolerability as first-line therapy for patients with uHCC.

Background: Given the superior performance of various therapies over sorafenib in advanced hepatocellular carcinoma (HCC) and the absence of direct comparisons, it is crucial to explore the efficacy of these treatments in phase III randomized clinical trials. Objectives: The goal is to identify which patients are most likely to benefit significantly from these emerging therapies, contributing to more personalized and informed clinical decision-making. Design: Systematic review and network meta-analysis. Data sources and methods: PubMed, Embase, ClinicalTrials.gov, and international conference databases have been searched from 1 January 2010 to 1 December 2023. Results: After screening, 17 phase III trials encompassing 18 treatments were included. In the whole-population network meta-analysis, the newly first-line tremelimumab plus durvalumab (Tre + Du) was found to be comparable with atezolizumab plus bevacizumab (Atezo + Beva) in providing the best overall survival (OS) benefit [hazard ratio (HR) 1.35, 95% confidence interval (CI): 0.93-1.92]. Concerning OS benefits, sintilimab plus bevacizumab biosimilar (Sint + Beva), camrelizumab plus rivoceranib (Camre + Rivo), and lenvatinib plus pembrolizumab (Lenva + Pemb) appear to exhibit similar effects to Tre + Du and Atezo + Beva. In the context of progression-free survival, Atezo + Beva seemed to outperform Tre + Du (HR: 0.66 CI: 0.49-0.87), while the effects are comparable to Sint + Beva, Camre + Rivo, and Lenva + Pemb. Upon comparison between Asia-Pacific and non-Asia-Pacific cohorts, as well as between hepatitis B virus (HBV)-infected and non-HBV-infected populations, immune checkpoint inhibitor (ICI)-based treatments seemed to exhibit heightened efficacy in the Asia-Pacific group and among individuals with HBV infection. However, combined ICI-based therapies did not show more effectiveness than molecular-targeted drugs in patients without macrovascular invasion and/or extrahepatic spread. As for grades 3-5 adverse events, combined therapies showed comparable safety to sorafenib and lenvatinib. Conclusion: Compared with sorafenib and lenvatinib, combination therapies based on ICIs significantly improved the prognosis of advanced HCC and demonstrated similar safety. At the same time, the optimal treatment approach should be tailored to individual patient characteristics, such as etiology, tumor staging, and serum alpha-fetoprotein levels. With lower incidence rates of treatment-related adverse events and non-inferior efficacy compared to sorafenib, ICI monotherapies should be prioritized as a first-line treatment approach for patients who are not suitable candidates for ICI-combined therapies. Trial registration: PROSPERO, CRD42022288172.
Lay summary/Key points The efficiency of various systemic therapies in advanced HCC patients with specific characteristics remains to be explored. This study revealed that the efficacy of ICI combined therapies is influenced by factors such as tumor staging, etiology, patient demographics, and more. Additionally, ICI monotherapies should be prioritized as a first-line treatment approach for patients who are not suitable candidates for ICI combined therapies. Complementing to recent guidelines, this study indicated that several critical factors needed to be took into consideration for patients with advanced HCC.
RESUMEN
Purpose: The aim of this study was to investigate the efficacy and safety of conversion surgery for advanced hepatocellular carcinoma (HCC) after hepatic arterial infusion chemotherapy (HAIC). Patients and Methods: Data from 172 HCC patients treated at Sun Yat-sen University Cancer Center between January 2016 and June 2021 with effective assessment of HAIC treatment response were retrospectively analyzed. Clinical pathological data, treatment process, survival, and occurrence of adverse events were recorded. Patients were grouped according to whether they achieved imaging remission after HAIC, underwent conversion surgery, and met the surgical resection criteria. Efficacy and safety were analyzed. Results: The median progression-free survival (PFS) and overall survival (OS) in the imaging remission group were 8.6 months and 26.3 months, respectively, which were longer than the 4.6 months (P<0.05) and 15.6 months (P<0.05) in the nonremission group. Compared with 6.7 months and 18.9 months in the HAIC maintenance group, the median PFS and median OS in the conversion surgery group were 16.5 months (P<0.05) and 45.0 months (P<0.05), but there was a higher risk of treatment-related hemoglobin decrease, alanine aminotransferase increase, aspartate aminotransferase increase, and total bilirubin increase (P<0.05). The risk of biliary fistula, abdominal hemorrhage and ascites in the HAIC conversion surgery group was higher than that of the single surgery group (P<0.05). Compared with the conversion surgery group, the median PFS and median OS of patients in the HAIC maintenance group who met the resection criteria were shorter: 7.1 months (P<0.05) and 21.7 months (P<0.05), respectively. All adverse events during the study were less than moderate, and no toxicity-related deaths occurred during follow-up. Conclusion: HAIC-based conversion therapy had acceptable toxic effects and could effectively stabilize intrahepatic lesions in advanced HCC, improve the survival benefit of patients, and provide some patients with the opportunity for conversion surgery to further improve prognosis.
RESUMEN
The high mortality rate in hepatocellular carcinoma (HCC) is partially due to the fact that a significant number of patients are diagnosed at an intermediate or advanced stage, with surgical treatment options unavailable. Conversion therapy, which involves both locoregional and systemic treatments, has the potential to downstage tumors in selected patients with initially unresectable HCC, thereby making surgical treatment a possibility and potentially increasing long-term survival. To optimize the conversion rate, it is necessary to maximize successful conversions and clearly define the target population for conversion treatment through a collaborative effort. In this review article, we summarize the clinical experience and evidence for conversion therapy in patients with 'potentially resectable' HCC from four perspectives: 1) defining the target population for conversion therapy, 2) selecting the appropriate conversion strategy, placing emphasis on the utilization of combination therapy that exhibits a significant objective response rate, 3) determining the timing and urgency of surgical resection, 4) promoting the adoption of a multidisciplinary team model. The authors are optimistic that with the continuous progress in treatment and a deeper understanding of HCC, the success rate of HCC conversion therapy will increase, and the overall survival of HCC patients will be prolonged.
RESUMEN
Liver cancer is the fourth leading cause of cancer-related mortality worldwide and hepatocellular carcinoma (HCC) is the most common primary liver cancer. In the present study, it was demonstrated that translocated promoter region (TPR) was upregulated in tumor tissues and associated with prognosis and immune infiltration in HCC. The clinical outcome of patients with HCC with aberrant expression of TPR was examined using multiple databases, including Gene Expression Omnibus, The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression, Kaplan-Meier (KM) Plotter and Xiantao tool. The clinicopathologic characteristics of patients from TCGA database that were associated with overall survival were assessed using Cox regression and KM analysis. The potential hallmarks associated with TPR expression were further predicted by Metascape and Gene Set Enrichment Analysis, and the relationship between TPR and immune infiltration was explored using the Tumor-Immune System Interactions Database and the Tumor Immune Estimation Resource. The results demonstrated that TPR expression was higher in HCC and its overexpression was associated with a worse prognosis, alongside a correlation with several clinical features. Furthermore, cell differentiation, a prospective new hallmark of cancer, was differentially enriched in the high TPR expression phenotype pathway. Moreover, TPR may also modulate the tumor immune microenvironment as it was signiï¬cantly associated with immunoregulators and chemokines, as well as different tumor inï¬ltration immune cells. According to the in vitro experiments, TPR silencing inhibited the phosphorylation of AKT and the proliferation of HCC cells. In summary, TPR may be a new marker and target for HCC therapy.
RESUMEN
Background: Hepatitis B virus (HBV) reactivation is a common complication in hepatocellular carcinoma (HCC) patients treated with chemotherapy or immunotherapy. This study aimed to evaluate the risk of HBV reactivation and its effect on survival in HCC patients treated with HAIC and lenvatinib plus PD1s. Methods: We retrospectively collected the data of 213 HBV-related HCC patients who underwent HAIC and lenvatinib plus PD1s treatment between June 2019 to June 2022 at Sun Yat-sen University, China. The primary outcome was the risk of HBV reactivation. The secondary outcomes were overall survival (OS), progression-free survival (PFS), and treatment-related adverse events. Results: Sixteen patients (7.5%) occurred HBV reactivation in our study. The incidence of HBV reactivation was 5% in patients with antiviral prophylaxis and 21.9% in patients without antiviral prophylaxis, respectively. The logistic regression model indicated that for HBV reactivation, lack of antiviral prophylaxis (P=0.003) and tumor diameter (P=0.036) were independent risk factors. The OS and PFS were significantly shorter in the HBV reactivation group than the non-reactivation group (P=0.0023 and P=0.00073, respectively). The number of AEs was more in HBV reactivation group than the non-reactivation group, especially hepatic AEs. Conclusion: HBV reactivation may occur in HCC patients treated with HAIC and lenvatinib plus PD1s. Patients with HBV reactivation had shorter survival time compared with non-reactivation. Therefore, HBV-related HCC patients should undergo antiviral therapy and HBV-DNA monitoring before and during the combination treatment.

BACKGROUND: The optimal subsequent management for patients with initially unresectable hepatocellular carcinoma (uHCC) who have achieved complete response (CR) following conversion therapy remains unclear. This study aims to evaluate the feasibility and outcomes of the watch-and-wait (W-W) strategy versus surgical resection (SR) for these patients. MATERIALS AND METHODS: This retrospective study reviewed patients with initially uHCC who underwent conversion therapy employing transarterial therapies combined with or without systemic therapies. Radiologic CR (rCR), clinical CR (cCR), and pathologic CR (pCR) were evaluated. Overall survival (OS) and progression-free survival (PFS) were compared between the W-W and SR groups. RESULTS: Among 1880 patients with uHCC who underwent conversion therapy, 207 (11.0%) achieved rCR. Finally, we enrolled 149 patients meeting the inclusion criteria, including 74 receiving W-W strategy and 75 undergoing SR. Among the 149 patients with rCR, the W-W group demonstrated comparable 3-year OS rates to the SR group (80.9 vs 83.1%, P =0.77), but demonstrated inferior PFS rates (14.4 vs 46.5%, P =0.002). These results remained consistent after propensity score matching. For the 57 patients who achieved cCR, the W-W group exhibited comparable 3-year OS (88.1 vs 87.9%, P =0.89) and PFS rates (27.8 vs 40.8%, P =0.34) compared to SR group. Among the 75 patients in the SR group, 31 (41.3%) achieved pCR and 44 (58.7%) reached non-pCR. When compared with patients with pCR, those who achieved rCR in the W-W group showed comparable OS but inferior PFS rates. Moreover, patients who achieved rCR in the W-W group displayed both comparable OS and PFS rates to those with non-pCR. CONCLUSION: The W-W strategy offered comparable survival outcomes to SR in patients with initially uHCC who achieved rCR or cCR after conversion therapy. For these patients, the W-W strategy could be offered as an alternative treatment option.

BACKGROUND: Indocyanine green (ICG) clearance test is a classical measurement of hepatic reserve, which involves surgical safety and patient recovery of hepatocellular carcinoma (HCC). The authors aim to compare effects of hepatic arterial infusion chemotherapy (HAIC) and transcatheter arterial chemoembolization (TACE) on liver function and outcomes of subsequent hepatectomy. MATERIAL AND METHODS: HCC patients receiving HAIC/TACE in SYSUCC with repeated ICG clearance tests were retrospectively enrolled. ICG eliminating rate (ICG-K), ICG retention rate at 15 min (ICG-R15) and ordinary laboratory tests were collected. Peri-therapeutic changes of values were compared between the groups. Propensity score matching (PSM) and inverse probability of treatment weighing (IPTW) were employed to validate findings. Post-hepatectomy liver failure (PHLF), overall survival (OS) and recurrence-free survival (RFS) were analyzed in patients with subsequent curative hepatectomy. RESULTS: Two hundred and four patients treated with HAIC ( n =130) and TACE ( n =74) were included. ΔICG-R15 was greater in the HAIC arm before matching (mean, 3.8% vs. 0.7%, P <0.001), after PSM (mean, 4.7% vs. 1.1%, P =0.014) and IPTW (mean, 2.0% vs. -3.6%, P <0.001). No difference was found for ΔALB, ΔALBI, ΔTBIL, ΔALT, ΔAST and ΔPT-INR. Multivariable analyses revealed elder age, cirrhosis, HAIC, greater ΔTBIL and ΔALBI were associated with deteriorating ICG-R15. Among those (105 for HAIC and 48 for TACE) receiving hepatectomy, occurrence of grade B/C PHLF (4.8% vs. 8.3%, P =0.616), OS (median, unreached vs. unreached, P =0.94) and RFS (median, 26.7 vs. 17.1 months, P =0.096) were comparable between the two arms. In subgroup analyses, preoperative HAIC yield superior RFS (median, 26.7 vs. 16.2 months, P =0.042) in patients with baseline ICG-R15 less than or equal to 10%. CONCLUSION: Preoperative FOLFOX-HAIC caused apparent impairment of ICG clearance ability than TACE yet comparable impact on liver function and post-hepatectomy outcomes.

BACKGROUND: To explore the role of gender in the incidence of chronic thromboembolic pulmonary hypertension after acute pulmonary embolism. METHODS: Two researchers search the PubMed Database, Embase Database and Cochrane Library Database from their establishment to October 2022, using Endnote software for document management and RevMan5.3 software for the meta-analysis of the included literature. A total of 11 studies are selected, including 5788 acute pulmonary embolism events and 391 patients (179 males and 212 females) with chronic thromboembolic pulmonary hypertension (CTEPH) under the stated conditions. The results show that there is no statistically significant difference in the incidence of CTEPH between males and females after PE (Pâ =â .28), with combined OR of 0.89 and 95% CI 0.72-1.10. RESULTS AND CONCLUSIONS: Gender is found to be absent as a factor in the incidence of CTEPH after acute pulmonary embolism. This may indicate that gender is not a risk factor for CTEPH and that female patients are not necessarily more likely to have a higher incidence than male patients. As such, accurate judgments should be made on the possible complications of all patients after acute pulmonary embolism, which will be conducive to early detection and intervention in the treatment of CTEPH.

Hepatocellular carcinoma (HCC) is one of the most common malignancies and the third leading cause of cancer-related deaths globally. Hepatic arterial infusion chemotherapy (HAIC) treatment is widely accepted as one of the alternative therapeutic modalities for HCC owing to its local control effect and low systemic toxicity. Nevertheless, although accumulating high-quality evidence has displayed the superior survival advantages of HAIC of oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX) compared with standard first-line treatment in different scenarios, the lack of standardization for HAIC procedure and remained controversy limited the proper and safe performance of HAIC treatment in HCC. Therefore, an expert consensus conference was held on March 2023 in Guangzhou, China to review current practices regarding HAIC treatment in patients with HCC and develop widely accepted statements and recommendations. In this article, the latest evidence of HAIC was systematically summarized and the final 22 expert recommendations were proposed, which incorporate the assessment of candidates for HAIC treatment, procedural technique details, therapeutic outcomes, the HAIC-related complications and corresponding treatments, and therapeutic scheme management.

BACKGROUND: High rate of tumor recurrence jeopardized the long-term survival of hepatocellular carcinoma (HCC) patients with complete response to transarterial chemoembolization (TACE). This study aims to evaluate the survival benefit of liver resection (LR) following the complete response to TACE for intermediate-stage HCC. METHODS: A total of 281 intermediate-stage HCC patients with complete response to TACE followed by persistent observation (TACE group) or LR (TLR group) from 01 January 2011 to 31 December 2021 from three institutions in China were included. Overall survival (OS) and disease-free survival (DFS) of patients were compared between the two groups by propensity score-matching (PSM). RESULTS: After PSM, the 1-year, 3-year, and 5-year OS rates were 91.4, 71.5, and 57.1% in the TACE group, and 96.6, 81.8, and 72.1% in the TLR group. The 1-year, 3-year, and 5-year DFS rates were 50.6, 22.6, and 6.8% in the TACE group, and 77.3, 56.3, and 38.7% in the TLR group. Compared with the TACE group, the TLR group showed significantly longer OS (HR, 0.528; 95% CI: 0.315-0.887; P =0.014) and DFS (HR, 0.388; 95% CI: 0.260-0.580; P <0.001). In patients beyond up-to-seven criterion, no difference was observed with OS (HR, 0.708; 95% CI: 0.354-1.419; P =0.329). LR following the complete response to TACE was safety. CONCLUSIONS: This study suggests that intermediate-stage HCC patients could benefit from LR following the complete response to TACE, resulting in longer OS and DFS. In addition, patients beyond up-to-seven could not benefit from the LR treatments.

BACKGROUND: The leading course of death in patients with advanced hepatocellular carcinoma (HCC) is intrahepatic progression and associated hepatic failure. The study aimed to evaluate the efficacy of locoregional therapy targeting intrahepatic lesions after intrahepatic progression for advanced HCC. METHODS: Consecutive 263 HCC patients who received lenvatinib combined with immunotherapy were reviewed. Until to last follow-up, 178 patients had disease progression:107 patients had intrahepatic progression (IP group) with or without extrahepatic progression, and 71 patients only had extrahepatic progression (EP group). After intrahepatic progression, 47 patients received systemic therapy (Systemic group), 23 patients received locoregional-systemic therapy (Loco-systemic group), and 37 patients received best supportive therapy (Supportive group). RESULTS: The EP group showed significantly longer OS (overall survival) than the IP group (not reached vs 16.2 months, P = 0.009). Median OS was significantly longer in the Loco-systemic group (20.3 v 8.8 months; P = 0.03) than in the Systemic group. The median PFS (progression-free survival) was 11.7 months in the Loco-systemic group and 5.3 months in the Systemic group (P = 0.046). In patients who progressed fast in first-line treatment, there was no significant difference in OS and PFS between the two groups. CONCLUSION: Intrahepatic progression was associated with a poorer survival outcome compared with extrahepatic progression in advanced HCC. After intrahepatic progression, additional locoregional therapy based on systemic therapy may offer clinical benefits on OS and PFS in second-line treatment, the benefits were limited to patients who had once achieved tumor control during their first-line treatments.
