Objective To explore the safety and efficacy of lenvatinib in combination with transarterial chemoembolization (TACE) and programmed death receptor 1 (PD-1) antibody in the treatment of recurrent liver cancer. Method The clinical data of 22 patients with unresectable recurrent liver cancer admitted to Department of Liver Surgery and Liver Transplantation Center, West China Hospital, Sichuan University and received the conversion therapy of lenvatinib+TACE+PD-1 antibody between January 2019 and January 2022 were retrospectively analyzed. Results All 22 patients experienced some degree of adverse events, with a grade 3 adverse event rate of 18.2% (4/22) and no grade 4 or higher adverse events. At 4 months of treatment, according to the modified response evaluation criteria solid tumors (mRECIST), 2 cases were in complete response (CR), 5 cases were in partial response (PR), and 6 cases were in stable disease (SD), 9 cases were in progressive disease (PD), and the objective response (CR+PR) rate (ORR) was 31.8% (7/22). At the last follow-up, there was 1 case in CR, 5 cases in PR, 1 case in SD, and 15 cases in PD, with an ORR of 27.3% (6/22). The 1-year overall survival (OS) rate was 83.8% and the 1-year progression-free survival (PFS) rate was 38.2%. In the subgroup analysis, the 1-year OS rate for patients with recurrent liver cancer with intrahepatic lesions (n=16) only was 86.2% [95%CI (77.1%, 95.3%)], the 1-year PFS rate was 46.9% [95%CI (34.0%, 59.8%)], and the ORR based on mRECIST criteria was 43.8% (7/16). Patients with intrahepatic combined with extrahepatic lesions (n=6) had a 1-year OS rate of 75.0% [95%CI (53.3%, 96.7%)] and a 1-year PFS rate of 16.7% [95%CI (15.0%, 31.9%)], and the ORR based on mRECIST criteria was 0% (0/6). There were no significant differences in OS (P=0.864) and PFS (P=0.125) between the two subgroups. The ORR of intrahepatic combined with extrahepatic lesions group was worse compared to the intrahepatic lesion group (P=0.049). Conclusion Lenvatinib in combination with TACE and PD-1 antibody is safe and effective in the treatment of unresectable recurrent liver cancer, but there are still many issues that deserve further exploration.

ObjectiveTo investigate the effects of lenvatinib combined with transarterial chemoembolization (TACE) and programmed death protein-1 (PD-1) monoclonal antibody (Abbreviated as LEN-TAP regimen) on residual liver volume and surgical safety in intermediate and advanced hepatocellular carcinoma (HCC). MethodsThe clinicopathologic data of patients with intermediate and advanced HCC were collected retrospectively, who underwent the LEN-TAP conversion therapy and surgical resection in the Department of Liver Surgery, West China Hospital, Sichuan University from October 2020 to December 2021. The total liver volume, tumor volume, and residual liver volume of the patients before and after conversion therapy were analyzed. ResultsA total of 48 patients were included, 26 of whom had partial remission and 22 had stable disease, the objective response rate was 54.2% (26/48) according to the Response Evaluation Criteria in Solid Tumours 1.1 after conversion therapy. Before and after conversion therapy, the total liver volumes including tumor were (1 607.15±712.22) mL and (1 558.03±573.89) mL [mean difference (MD) and 95% confidence interval (CI)=–57.42(–134.30, 19.46), t=–1.503, P=0.140], the total liver volumes excluding tumor tissue were (1 095.28±227.60) mL and (1 260.31±270.71) mL [MD(95%CI)=165.03(128.13, 201.93), t=8.997, P<0.001], the tumor volumes were 260.25(107.75, 699.50) mL and 121.73 (33.00, 332.88) mL [MD(95%CI)=–222.45(–296.46, –148.44), Z=–5.641, P<0.001], and the residual liver volumes were (493.62±154.51) mL and (567.83±172.23) mL [MD(95%CI)=74.21(54.64, 93.79), t=7.627, P<0.001], respectively. The increase rates of tumor volume and residual liver volume after conversion therapy were (–53.34±33.05)% and (16.34±15.16)%, respectively. The conversional resections were successfully completed in all patients, with 13 (27.1%) cases experiencing postoperative complications and without occurrence of postoperative liver failure. ConclusionThe data analysis results of this study indicate that the LEN-TAP conversion therapy can shrink tumor volume and increase the residual liver volume for patients with intermediate and advanced HCC, which helps to improve the safety of conversion resection.
ObjectiveTo compare the value of apparent diffusion coefficients (ADCs) of MR-DWI at different b values in evaluating the progression of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).MethodsAll of 168 patients with HCC who met the inclusion and exclusion criteria and received the TACE for the first time in the Characteristic Medical Center of PAPF were collected retrospectively, who were divided into a stable group and progressive group according to the results of MRI evaluation at the 6th month after the TACE treatment. The clinical and imaging data of the two groups were compared before the TACE treatment. The Cox proportional hazard regression model was used to analyze the risk factors for the disease progression after the TACE treatment. The receiver operating characteristic curve (ROC) was used to analyze the predicting of efficacy evaluation of TACE by the ADC values at different b values.ResultsCompared with the stable group, the proportions of hepatitis B cirrhosis history, portal vein tumor thrombus, and arteriovenous fistula were higher (P<0.05), and the BCLC stage and Child Pugh grade were worse (P<0.05), and the ADC values were higher (P<0.05) in the progressive group. The results of Cox analysis showed that the ADC values at b=600 and 800 s/mm2 before the TACE, history of hepatitis B cirrhosis, portal vein tumor thrombus, arteriovenous fistula, advanced BCLC stage and Child-Pugh grade were the risk factors for the progression at the 6th month after the TACE treatment. When the b value was 800 s/mm2, the ADC value had the highest efficacy in predicting the outcome of patients (area under ROC curve was 0.746), and the best diagnostic cut-off point was 1.20×10–3 mm2/s, the sensitivity was 73.3% and the specificity was 71.8%.ConclusionADC value of MR-DWI could predict progression after TACE in patients with HCC, and ADC value of 800 s/mm2 has a better predictive value for them.
ObjectiveTo investigate the significance of apparent diffusion coefficient (ADC value) for pretrea-tment prediction of short-term treatment effect in patients with hepatocellular carcinoma (HCC) who underwent transca-theter arterial chemoembolization (TACE). MethodsA total of twelve HCC patients with twenty-three HCC lesions who underwent TACE in our hospital from May. 2014 to May. 2015 were enrolled prospectively, to explore the difference between pre-and post-TACE in diameter of tumor, ADC value of HCC lesions, ADC value of liver parenchyma, and analyze the predictive significance of ADC value of HCC lesions for TACE in treatment of HCC. ResultsThere were no statistical difference between pre-and post-TACE in diameter of HCC lesions and ADC value of liver parenchyma (P=0.635, P=0.473), but the ADC value of HCC lesions was higher after TACE than pre-TACE (P=0.003). After TACE, the area of necrosis in HCC lesions was≥50% in 17 lesions (73.9%, good effect group), and <50% in 6 lesions (26.1%, poor effect group). Compared with poor effect group, ADC values of HCC lesions in good effect group were both higher before and after TACE (P<0.050). Area under ROC curve (AUC value) of ADC value in HCC lesions before TACE for predicting the effect of TACE was 0.690 (95% CI:0.510-0.879), with the sensitivity and specificity of 82.3% (95% CI:65.5%-93.2%) and 53.8% (95% CI:25.1%-80.8%) respectively, and the demarcation point for good effect and poor effect was 1.24×103 mm2/s. ConclusionThis preliminary study demonstrates that the ADC value of HCC lesions before TACE may be a useful indicator to predict early response of TACE in treatment of HCC.
ObjectiveTo systematically evaluate efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with Huaier granules in treatment of primary liver cancer (PLC).MethodsThe databases including the PubMed, Embase, Cochrane Library, Wanfang Data, CNKI, VIP were searched to obtain the relevant literatures of Huaier granule combined with TACE therapy (Huaier+TACE group) and alone TACE therapy (TACE group) in the treatment of PLC. The short-term curative effects (objective response rate and disease control rate), 6 and 12-month survival rates, immune function change, and adverse reactions were extracted. The RevMan 5.3 software was applied to carry out the meta analysis.ResultsFifteen studies involving 1 781 cases were enrolled in this study, of which 876 cases underwent the Huaier+TACE, 905 underwent the TACE. The meta analysis results showed that the objective response rate and disease control rate, 6 and 12-month survival rates of the Huaier+TACE group were significantly more superior as compared with of the TACE group (P<0.05), the adverse reaction incidence had no significant difference (P>0.05). Compared with the TACE group, the CD4 +/CD8 + of the Huaier+TACE group was significantly improved (P<0.05).ConclusionFrom results of meta analysis, Huaier granule combined with TACE could improve therapeutic effect, increase survival rate, and improve life quality of PLC.
The treatment of liver cancer is still a challenge in the world, and it is mainly refers to hepatocellular carcinoma (HCC). There are many factors affecting the overall survival rate of HCC; the recurrence of HCC is the main risk factor affecting the survival of patients, hence, it is urgent to explore the clinical treatment of recurrent HCC to obtain long-term survival of the patients. Up to now, surgical treatment is a radical treatment for HCC. Similarly, liver resection and liver transplantation are still the main therapy methods for recurrent HCC. In addition, radiofrequency ablation and transcatheter arterial chemoembolization and other local treatments still play an irresistible role. Therefore, emphasizing the postoperative follow-up of patients, diagnosing recurrent HCC in early stage, paying attention to the risk factors of HCC recurrence and selecting a suitable treatment plan for individuals are critical ways to prolong the survival of patients.
Objective To compare therapeutic effects of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and transcatheter arterial chemoembolization (TACE) on patients with advanced hepatocellular carcinoma. Methods Thirty-five patients with advanced hepatocellular carcinoma admitted in the Department of Hepatobiliary and Pancreatic Surgery of Shiyan Taihe Hospital Affiliated to Hubei University of Medicine from August 1, 2014 to August 1, 2015 were randomly divided into ALPPS group and TACE group, in which 17 cases treated by the ALPPS and 18 cases treated by the TACE. The survival, changes of liver function and life quality, postoperative complications and mortality were compared in these two groups. The follow-up was performed by the telephone and the outpatient. Results ① The baselines such as the age, gender, diameter of tumor, complications had no significant differences in these two groups (P>0.05). ② The changes of liver function and life quality after operation in the ALPPS group were significantly better than those in the TACE group (P<0.05). ③ The complications after operation were observed in 5 cases (there were 2 cases of bile leakage, 1 case of intraabdominal bleeding, 1 case of peritoneal effusion, and 1 case of pulmonary infection) in the ALPPS group, which in 13 cases (there were 6 cases of nausea and vomiting, 4 cases of liver function damage, 2 cases of granulocytopenia, 1 case of fever) in the TACE group. The rate of the overall complications in the ALPPS group was significantly lower than that in the TACE group (5/17versus 13/18, P=0.018). ④ The overall survival in the the ALPPS group was significantly better than that in the TACE group (P=0.024). During follow-up period, the deaths happened in 3 cases duo to hepatocellular carcinoma and 1 case duo to traffic accident, 1 case was lost on month 8, 12 cases were still alive in the ALPPS group; the deaths happened in 10 cases duo to hepatocellular carcinoma, 1 case duo to coronary disease, and 1 case duo to cerebral infarction, 6 cases were still alive in the TACE group. Conclusion Preliminary results of limited cases in this study show that ALPPS has a better effect than TACE on patients with advanced hepatocellular carcinoma.
Objective To summarize the blood supply to the sources and characteristics of advanced breast cancer，and explore the method，efficacy，and clinical applications of preoperative super-selective arterial catheterization chemoembolization under DSA for it. Methods Sixty patients with advanced breast cancer confirmed by the aspiration biopsy from February 2007 to October 2011 in this hospital were selected. Seldinger method was used，distributing of the tumor blood supply artery was identified and intubated the target artery by super-selective arterial catheterization via the femoral artery puncture under the DSA. Then，pirarubicin 60 mg plus paclitaxel 120 mg of two chemotherapy drugs was injected into slowly the target artery and the intervention infusion chemotherapy was performed，finally the tumor blood supply artery was embolizated by gelatin sponge particle. Results A total of 112 conclusive blood supply artery in 60 patients with DSA were found，including eight cases of single blood supply artery，52 cases of multiple blood supply arteries，mainly in the lateral thoracic artery and （or） internal thoracic artery-based. The complete remission rate was 25.0% （15/60），partial remission rate was 73.3% （44/60），stable disease rate was 1.7% （1/60），the total effective rate was 98.3% （59/60）. There was no progression disease. The median remission duration was 19 months，median survival time was 40 months. Conclusions The location of the original foci of breast cancer is closely related to blood supply arteries. The tumor in the lateral of the breast mainly dominates by the lateral thoracic artery blood supply. The tumor in the inner breast mainly dominates by the internal thoracic artery blood supply. The preoperative super-selective arterial catheterization chemoembolization under DSA can obviously improve the therapeutic effect，long-term survival，and the target of interventional chemoembolization.
Objective To investigate the growth of tumors and the natural life length of the rats after the adriamycinethylcellulose microspheres(ADM-EC mc) were injected in the rats bearing transplantable liver cancer through their hepatic arteries.Methods ADM-EC mc were infused into the proper hepatic arteries of the Wistar rats (W256). All of the rats were divided randomly into five groups, group 1: control, group 2: normal saline, group 3: conventional ADM, group 4: placebo ethylcellulose microspheres, and group 5: ADM-EC mc.
