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.
To challenge the 15% enhancement of 5-year survival of cancer for the plan of “Health-China 2030”, we must strive the following measurements to complete the 15% enhancement of 5-year survival of liver cancer: conduct conversion therapy and conversion to resectability for the 70% of unresectable intermediate-to-advanced stage liver cancer so as to prolong survival; try our best to identify and treat the people of HBV and HCV infection, and to screen the risk people so as to reduce the incidence of liver cancer and the proportion for intermediate-to-advanced stage liver cancer; continue to try our best in the full course management of liver cancer under the frame of MDT.
Objective To summarize the current progress in diagnosis and treatment of polycystic liver disease, and provide ideas for further research direction and clinical practice of polycystic liver disease. Method The domestic and foreign literature about polycystic liver disease was reviewed, screened, and summarized. Results The diagnosis, evaluation, and classification of polycystic liver disease were mainly performed clinically by abdominal ultrasound and CT. Surgical treatment was the main treatment, including aspiration sclerotherapy, fenestration, segmental hepatectomy, and liver transplantation. Conclusions The classification and evaluation scheme of polycystic liver disease needs to be improved, and its medical treatment still needs further research. Estrogen receptor and gonadotropin-releasing hormone receptor are promising therapeutic targets.
Objective To investigate the prediction of baseline neutrophil-lymphocyte ratio (NLR) on the prognosis of unresectable hepatocellular carcinoma (uHCC) treated with transarterial chemoembolization (TACE) + lenvatinib + camrelizumab. Method The clinical data of 58 patients treated with TACE + lenvatinib + camrelizumab in the Department of Liver Surgery of West China Hospital of Sichuan University from June 2020 to May 2021 were analyzed retrospectively. Results Among the 58 cases included, 7 cases were complete response (CR), 37 cases were partial response (PR), 11 cases were stable disease (SD), and 3 cases were progressive disease (PD). All cases had different degrees of adverse events, including 58 cases of grade 1, 36 cases of grade 2, 35 cases of grade 3, and 1 case of grade 4. The overall response rate (ORR) and disease control rate (DCR) based on modified Response Evaluation Criteria in Solid Tumors (mRECIST) were 75.9% (44/58) and 94.8% (55/58), respectively. The hepatectomy rate was 31.0% (18/58) and the conversion success rate was 37.9% (22/58). Multivariate logistic regression analysis showed that NLR was an independent risk factor for ORR (OR=0.093, P=0.008). All cases were followed up for 16–60 weeks, with a median follow-up of 34 weeks. Overall survival situation (χ2=4.163, P=0.041) and progression free survival situation (χ2=10.626, P=0.001) in the low NLR group were better than those of the high NLR group. Conclusion NLR has clinical significance in predicting the prognosis of uHCC cases underwent TACE + lenvatinib + camrelizumab, which is worthy of further study.
ObjectiveTo explore the application of the technique of liver venous deprivation (LVD) for two-stage radical hepatectomy in patient with liver cancer underlying hepatitis B virus infection.MethodsA 53 years old patient diagnosed with central primary liver cancer (Ⅴ/Ⅷ segment) could not receive standard right hepatectomy since his future liver remnant was insufficient, so the LVD was performed to induce FLR growth. The general condition and CT scan were repeated at 1-, 2- and 3-week after LVD, the FLR and FLR weigh/ body weight ratio were calculated.ResultsThe FLR and FLR weight/body weight ratio before LVD were 24.2% and 0.459%, the FLR at 1-, 2- and 3-week after LVD were 29.5%, 38.3% and 44.4% respectively, the FLR weight/body weight were 0.545%, 0.707% and 0.820% at 1-, 2- and 3-week after LVD. The standard right hepatectomy was undertaken successfully at 25 days after LVD and discharged safely.ConclusionThe LVD technique could induce a rapid and large FLR volume and offer opportunity for patients with insufficient FLR to receive two-stage radical hepatectomy, is a novel method to induce FLR growth effectively.
ObjectiveTo explore the safety and effectiveness of transarterial chemoembolization (TACE) combined with lenvatinib and programmed cell death protein-1 (PD-1) antibody in the conversion resection for intermediate and advanced unresectable hepatocellular carcinoma (HCC), and to provide new treatment strategies for the treatment of intermediate and advanced unresectable HCC. MethodThirty-eight intermediate and advanced unresectable HCC patients treated at West China Hospital of Sichuan University from October 2020 to June 2021 were prospectively included in our study, all patients treated with TACE + lenvatinib + PD-1 antibody, and the clinical data of these 38 patients were summarized. ResultsThe last evaluation time for the 38 patients was October 20, 2021. According to the mRECIST standard for tumor efficacy evaluation, the objective response rate was 84.2% (32/38), the disease control rate was 94.7% (36/38); the conversion success rate based on imaging was 55.3% (21/38), the actual conversion resection rate was 52.6% (20/38). The incidence of adverse events was 100%, of which 22 patients had grade 3 adverse events, and there was no ≥ grade 4 adverse events. All patients were followed up, the follow-up time was 16–52 weeks, and the median follow-up time was 33.5 weeks. During the follow-up period, only two patients had tumor progression, of which one patient died due to disease progression, and there was no postoperative recurrence. ConclusionsLenvatinib combined with TACE and PD-1 antibody is safe for the treatment of intermediate and advanced unresectable HCC. Triple therapy can achieve satisfactory conversion resection rate of intermediate and advanced unresectable HCC, which will provide a new treatment strategy for it.
Objective To summarize the effect of lenvatinib + transarterial chemoembolization (TACE) + programmed cell death protein-1 (PD-1) antibody in the treatment of hepatocellular carcinoma with main portal vein tumor thrombus and cavernous transformation. Methods In this study, we reported the clinical data of four patients with hepatocellular carcinoma with main portal vein tumor thrombus and cavernous transformation who received conversion therapy with lenvatinib combined with TACE and PD-1 antibody in West China Hospital. Results Among the four patients, two patients achieved complete response and two achieved partial response; tumor markers were significantly decreased after combination treatment. However, all four patients failed to undergo hepatectomy. ConclusionsLenvatinib + TACE + PD-1 antibody is effective for hepatocellular carcinoma with main portal vein tumor thrombus and cavernous transformation. However, there are still many problems worthy of further discussion.
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.
