Hepatic Arterial Infusion Chemotherapy Combined with Lenvatinib Plus Humanized Programmed Death Receptor-1 in Patients with High-Risk Advanced Hepatocellular Carcinoma: A Real-World Study.

Purpose: The treatment of hepatocellular carcinoma (HCC) patients with high-risk features (Vp4, and/or tumor occupancy≥50%) has not been standardized and has poor outcomes. The present study aimed to assess the safety, efficacy, and prognostic impact of lenvatinib, hepatic arterial infusion chemotherapy (HAIC), and humanized programmed death receptor-1 (PD-1) in treating high-risk patients and to explore the biomarkers that may predict the efficacy. Methods: HCC patients with high-risk features treated with lenvatinib, HAIC, and PD-1 were analyzed retrospectively. Overall survival (OS), progression-free survival (PFS), duration of response (DOR), objective response rate (ORR), and disease control rate (DCR) were calculated to evaluate the antitumor efficacy. Treatment-related adverse events (TRAEs) were analyzed to assess the safety profiles. Results: Between February 2020 and July 2022, 97 patients were enrolled in this retrospective cohort study. The median follow-up time was 447 days. During analysis, 65 patients had disease progression, and 39 patients died. The median PFS and OS were 295 and 579 days, respectively. According to RECIST 1.1 and mRECIST, the ORR was 64.9% and 78.3%, respectively, and the DCR was 92.8%. The median and intrahepatic DOR was 363 and 462 days, respectively. Treatment-related grade 3 or 4 adverse events occurred in 64 (65.9%) patients, and the most common adverse events were hypertension (9.3%), thrombocytopenia (7.2%), and elevated aspartate transaminase (7.2%). Participants with low levels of serum procalcitonin (PCT) had satisfactory prognosis. Conclusion: Lenvatinib, HAIC, and PD-1 were safe and showed promising antitumor activity against HCC with high-risk features. The initial levels of procalcitonin might be the predictive biomarkers for the combined treatment.

CalliSpheres drug-eluting beads transarterial-chemoembolization in the treatment of liver metastases from breast cancer: Initial experience in 14 patients.

ABSTRACT: Breast cancer patients with liver metastases are associated with high mortality. However, no standardized treatment approach is available for these patients who have undergone chemotherapy and hormonal therapy. We aimed to assess the clinical outcomes of patients with breast cancer liver metastases (BCLM) who underwent drug-eluting beads used for transarterial-chemoembolization (DEB-TACE).We retrospectively enrolled 14 patients with 39 lesions who underwent DEB-TACE for liver metastases following mastectomy for primary breast cancer. The incidence of complications, overall survival (OS), and local tumor progression-free survival (PFS) were assessed.A total of 14 patients with 39 liver metastases were treated with DEB-TACE from July 2017 to July 2020. The objective response rates (ORR) and disease control rates (DCR) were 71.4% and 92.8% at the 3-month period and 50% and 71.4% at the 6-month period, respectively. During the follow-up period the local tumor PFS was 8.0 months. The median OS was 20.0 months (range, 8-40 months) and the 1-, 2-year OS rates were 84.4% and 47.4%, respectively. No severe complications caused by this technique were detected.DEB-TACE for BCLM was characterized as a low trauma technique, with a limited number of complications. The results indicated that this method was safe and effective for patients with BCLM and could be widely adopted as a palliative treatment in clinical practice.

Effect of partial splenic embolization on transarterial chemoembolization for hepatocellular carcinoma with hypersplenism.

ABSTRACT: This study retrospectively studied transarterial chemoembolization (TACE) combined with partial splenic embolization (PSE) in the treatment of hepatocellular carcinoma (HCC) with severe hypersplenism.Seventy patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stage B or C with hypersplenism were divided into non-partial splenic embolization group (N-PSE, n = 51) and partial splenic embolization group (PSE, n = 19). The N-PSE group was further divided into N-PSE with mild to moderate hypersplenism (N-PSE-M, 47 cases) and N-PSE with severe hypersplenism (N-PSE-S, 4 cases).In the PSE group, leukocytes, neutrophils, lymphocytes, and platelets were significantly increased (P < .05) and were significantly different from that in the N-PSE group (P < .05). In the N-PSE group, except for a slight increase in neutrophils, other blood cells were decreased, including lymphocytes that were significantly decreased (P < .05). There was no significant difference in the changes of liver function between the 2 groups before and after surgery (P > .05). The analysis showed a significant increase in ascites after 6 months of TACE in the N-PSE group (P < .05). According to the follow-up results, the median overall survival (OS) in the PSE group was 24.47 ±â€Š3.68 (months) and progression-free survival (PFS) was 12.63 ±â€Š4.98 (months). Regardless of OS or PFS, the PSE group was superior to the N-PSE group and its subgroups, with a statistically significant difference in PFS between the N-PSE group and PSE group (P < .05). Moreover, the time of extrahepatic progression was significantly earlier in the N-PSE group than in the PSE group (P < .05). N-PSE-S group had the worst prognosis, and PFS and OS were worse than the other 2 groups, suggesting that PSE in severe hypersplenism may improve PFS and OS.In patients with HCC and severe hypersplenism, TACE should be actively combined with PSE treatment.

Type of Necrosis Influences Prognosis in Hepatocellular Carcinoma After the First Transarterial Chemoembolization.

BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common tumors. Transarterial chemoembolization (TACE) is the first choice of treatment for intermediate HCC and an important treatment option for advanced HCC. This retrospective study compared the prognosis between patients showing coagulative necrosis and patients showing liquefactive necrosis after the first TACE procedure. MATERIAL AND METHODS We divided 171 patients with Barcelona Clinic Liver Cancer (BCLC) Stage B or C HCC into 2 groups; a coagulative necrosis group (79 patients) and a liquefactive necrosis group (92 patients). The coagulative and liquefactive necroses were identified by computed tomography after the first TACE procedure. Kaplan-Meier analysis was used to identify the differences in the overall survival (OS) and progression-free survival (PFS) between the 2 groups, and the associated risk factors and safety of TACE were analyzed. RESULTS The median OS durations were 23.27±1.40 months and 8.83±2.15 months (P=0.004) and the median PFS durations were 9.33±0.96 months and 3.70±0.44 months (P=0.002) in the coagulative necrosis and liquefactive necrosis groups, respectively. Intrahepatic in situ progression, new intrahepatic metastasis, and extrahepatic progression occurred significantly earlier in the liquefactive necrosis group (P<0.05). Univariate analysis and multivariate analyses showed liquefactive necrosis was the main risk factor for OS. There was no significant difference in the hepatic function impairment or post-embolism syndrome after TACE. CONCLUSIONS After the first TACE procedure, the patients with liquefactive necrosis experienced recurrence and metastasis earlier and had a worse prognosis. Therefore, these patients should be considered for earlier administration of targeted therapies or immunotherapies after TACE.

Transcatheter arterial chemoembolization (TACE) for lymph node metastases in patients with hepatocellular carcinoma.

OBJECTIVE: To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) with regional lymph node metastases. METHODS: Forty-eight patients with HCC and regional lymph node metastases were enrolled in this study. The patients were allocated into two groups: Group A (28 patients) underwent TACE for both intrahepatic tumors and lymph node metastasis and Group B (20 patients) received TACE for intrahepatic tumors only. RESULTS: The patients were followed-up by contrast enhanced CT scan 6-8 weeks after TACE treatment. In Group A, seven and nine patients achieved complete and partial response for lymph node metastasis, respectively, with 1-year and 2-year overall survival rates of 60.7% and 35.7%, respectively. In contrast, none of the patients in Group B achieved a complete response, whereas four patients achieved a partial response. The 1-year and 2-year survival rates for the patients in Group B were 40% and 0%, respectively. The difference in survival between the two groups was statistically significant (P = 0.001). CONCLUSIONS: TACE is an effective treatment to regional lymph node metastasis in HCC without significant side effects and could provide survival benefits to the patients with advanced HCC.

Pure transcatheter arterial chemoembolization therapy for intrahepatic tumors causes a shrink in pulmonary metastases of hepatocellular carcinoma.

OBJECTIVE: Pulmonary metastasis of hepatocellular carcinoma (HCC) could be defined as advanced HCC and systematic treatment is the main therapeutic modality. However, local therapy of intrahepatic tumor, which is significantly associated with the prognosis of HCC, remains important for advanced HCC. METHODS: Twenty-six HCC patients with pulmonary metastasis underwent intrahepatic transcatheter arterial chemoembolization (TACE). We investigated the progression of lung metastastic tumors, overall survival and risk factors related to survival of these patients. RESULTS: Of the 26 patients who underwent TACE for one to four times, 10 patients achieved complete remission (CR) of intrahepatic tumors and among these 10 patients, 4 patients successfully received hepatic artery-venous shunt embolization combined with TACE. The lung metastasis lesions also achieved CR and the survival time was significantly longer than the other 22 patients. The lung metastastic lesions of the other 6 patients of intrahepatic tumors achieved stable disease (SD). Six patients acquired partial remission (PR) of intrahepatic tumors after TACE, while the lung metastastic lesions showed SD or progress disease (PD). Patients who showed CR and PR of intrahepatic tumors had longer survival time than patients with SD and PD. Portal vein tumor thrombus and size of the lung metastastic lesions were significant prognostic factors in these advanced HCC patients. CONCLUSIONS: With respect to HCC patients with lung metastasis, TACE was an effective and important therapeutic tool to control pulmonary metastatic tumor growth, and prolong the survival of advanced HCC patients, especially patients with hepatic artery-venous shunt.

Therapeutic value of transcatheter arterial chemoembolization combined with portal vein embolization for primary hepatocellular carcinoma with portal vein tumor thrombus: a pilot study.

AIM: To compare clinical outcome and safety of transcatheter arterial chemoembolization (TACE) + portal vein embolization (PVE) with TACE alone in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT). METHODS: We retrospectively collected patients of HCC with PVTT treated with TACE (5-FU, oxaliplatin and mitomycin) or TACE + PVE (doxorubicin) between October 2000 and July 2008. Outcomes evaluated include overall survival, response to treatment and side effects. RESULTS: One hundred and sixteen patients were assessed. The median follow-up of TACE group and TACE + PVE group was 83 and 85 months, respectively. The tumor response rates were respectively 48/64 and 49/52. The 1-, 3- and 5-year overall survival rates for the TACE and TACE + PVE groups were 39/64, 16/64, 0/64 and 42/52, 19/52, 6/52 respectively (P = 0.015, 0.046 and 0.002, respectively). Three factors were shown as the risk factors which affect the survival of patients: treated by TACE + PVE or TACE; type of PVTT; and absence of cirrhosis. CONCLUSION: TACE + PVE may be better than TACE alone to treat primary HCC with PVTT.

The association of HMGB1 expression with clinicopathological significance and prognosis in hepatocellular carcinoma: a meta-analysis and literature review.

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer, and it is the second most common cancer-related mortality globally. The prognostic value of high mobility group box 1 (HMGB1) remains controversial. The purpose of this study is to conduct a meta-analysis and literature review to evaluate the association of HMGB1 expression with the prognosis of patients with HCC. METHODS: A detailed literature search was made in Medline, Google Scholar and others for related research publications. The data were extracted and assessed by two reviewers independently. Analysis of pooled data were performed, Hazard Ratio (HR) and mean difference with corresponding confidence intervals (CIs) were calculated and summarized respectively. RESULTS: 10 relevant articles were included for this meta-analysis study. HMGB1 mRNA levels in HCC were significantly higher than those in normal (p<0.00001) and para-tumor tissues (p = 0.002) respectively. The protein levels of HMGB1 in HCC were significantly higher than those in para-tumor tissues (p = 0.005). Two studies reported the serum HMGB1 levels in patients with HCC of TNM stages, and indicating significantly different between stage I and II, stage II and III, as well as stage III and IV (two studies showed p<0.01 and p<0.001 respectively). The overall survival (OS) was significantly shorter in HCC patients with high HMGB1 expression compared those with low HMGB1 expression and the pooled HR was 1.31 with 95% CI 1.20-1.44, Z = 5.82, p<0.0001. Two additional studies showed that there were higher serum HMGB1 levels in patients with chronic hepatitis than those in healthy people (p<0.05). CONCLUSIONS: The results of this meta-analysis suggest that HMGB1 mRNA and protein tissue levels in the patients with HCC are significantly higher than those in para-tumor and normal liver tissues respectively. Tissue HMGB1 overexpression is a potential biomarker for HCC diagnosis, and it is significantly associated with the prognosis of patients with HCC.

Association of serum microRNA expression in hepatocellular carcinomas treated with transarterial chemoembolization and patient survival.

BACKGROUND AND AIM: Hepatocellular carcinoma (HCC) is one of the most deadly tumors. Transarterial chemoembolization (TACE) is effective for unresectable HCC. In recent years, miRNAs have been proposed as novel diagnostic and prognostic tools for HCC. This study aimed to identify whether microRNAs (miRNAs) can serve as biomarkers to reliably predict outcome before HCC patients are treated with TACE. METHODS: Eleven miRNAs (miR-, miR-19a, miR-101-3p, miR-199a-5p, miR-200a, miR-21, miR-214, miR-221, miR-222, miR-223 and miR-, -5p) were quantified by quantitative real-time PCR (qRT-PCR) in 136 HCC patients' serum before they received TACE therapy. Univariate and multivariate analysis were used to identify the prognostic value of clinical parameters and miRNAs. Area under the receiver operating characteristic curve (AUC) was used to evaluate the prediction potency. RESULTS: The levels of some miRNAs were dramatically associated with clinicopathologic features regarding Child-Puge class, AFP, tumor size and satellite nodules. Univariate analysis revealed that miR-200a, miR-21, miR-122 and miR-224-5p were significantly associated with patients' survival. Multivariate analysis demonstrated that AFP, satellite nodules and miR-200a were the independent prognostic factors associated with survival in this cohort (p = 0.000, 0.001, 0.000, respectively). The probability of the prognostic accuracy of miR-200a was 81.64% (74.47% specificity and 88.76% sensitivity), which was higher than the classifier established by combination of AFP and satellite nodules (76.87% probability, 70.21% specificity and 69.66% sensitivity). Furthermore, the combination of AFP, satellite nodules and miR-200a demonstrated as a classifier for HCC prognosis, yielding a ROC curve area of 88.19% (93.62% specificity and 68.54% sensitivity). CONCLUSIONS: Our study indicated that serum miR-200a may prognosticate disease outcome in HCC patients with TACE therapy. Therefore, miR-200a can potentially guide individualized treatment for HCC patients with a high risk of TACE treatment failures.
