Treatment Of Primary Liver Cancer Research Articles

Report of the 23rd nationwide follow-up survey of primary liver cancer in Japan (2014-2015).

For the 23rd Nationwide Follow-up Survey of Primary Liver Cancer in Japan, data from 20889 newly registered patients and 42274 previously registered follow-up patients were compiled from 516 institutions over a 2-year period from January 1, 2014 to December 31, 2015. Basic statistics compiled for patients newly registered in the 23rd survey were cause of death, past medical history, clinical diagnosis, imaging diagnosis, treatment-related factors, pathological diagnosis, recurrence status, and autopsy findings. Compared with the previous 22nd survey, the population of patients with hepatocellular carcinoma (HCC) was older at the time of clinical diagnosis, had more female patients, had more patients with non-B non-C HCC, had smaller tumor diameter, and was more frequently treated with hepatectomy. Cumulative survival rates were calculated for HCC, intrahepatic cholangiocarcinoma, and combined hepatocellular cholangiocarcinoma (combined HCC and intrahepatic cholangiocarcinoma) by treatment type and background characteristics for patients newly registered between 2004 and 2015 whose final outcome was survival or death. The median overall survival and cumulative survival rates for HCC were calculated by dividing patients by combinations of background factors (number of tumors, tumor diameter, Child-Pugh grade, or albumin-bilirubin grade) and by treatment type (hepatectomy, radiofrequency ablation therapy, transcatheter arterial chemoembolization, hepatic arterial infusion chemotherapy, and systemic therapy). The same values were also calculated according to registration date by dividing patients newly registered between 1978 and 2015 into five time period groups. The data obtained from this nationwide follow-up survey are expected to contribute to advancing clinical research and treatment of primary liver cancer in the world.

The therapeutic principle of combined clearing heat and resolving toxin plus TACE on primary liver cancer: A systematic review and meta-analysis

Ethnopharmacological relevanceTranscatheter arterial chemoembolization (TACE) is recommended as the first-line therapy for unresected primary liver cancer (PLC), but only partial patients could benefit from TACE due to the serious adverse reactions. Clearing heat and resolving toxin (CHRT), one of most critical traditional Chinese medicine (TCM) therapeutic principles, has been widely used in the treatment of PLC patients especially after TACE. However, there is no enough clinical evidence to confirm the efficacy and safety of the combined therapy. Aim of the studyTo comprehensively evaluate the efficacy and safety of the combined CHRT-CHF with TACE in the treatment of PLC. Materials and methods7 databases were searched from their inception until February 1, 2023. The primary outcomes included survival rate (1-, 2-year), objective response rate (ORR) and disease control rate (DCR), liver function indicators (AST, ALT), adverse reactions including fever, upper digestive tract side and myelosuppression, AFP were selected as the secondary outcomes. RevMan5.4 software was used to evaluate the quality of included studies; meta-analysis, subgroup analysis, meta-regression analysis, publication bias and trial sequential analyses (TSA) was conducted by Stata software 12.0. ResultsThere were 40 RCTs involving 3649 patients. Patients treated with TACE plus CHRT-CHF showed significantly better 1-, 2-year survival (respectively: OR, 2.23 [1.67–2.97]; OR, 2.13 [1.56–2.92]), ORR (OR, 2.14 [1.82–2.52]), DCR (OR, 2.13 [1.73–2.62]) compared with TACE alone. There was a decreased incidence of aspartate transaminase (AST), alanine transaminase (ALT), alpha-fetoprotein (AFP) and postembolization syndrome (PES) in patients receiving the combined TACE with CHRT-CHF compared with TACE alone. Subgroup analysis found that lower proportion (20–30%) of CHRT-CHF significantly enhanced survival rate and DCR, higher proportion (≥40%) of CHRT-CHF reduced PES after TACE treatment. ConclusionThe efficacy and safety of the combined CHRT-CHF with TACE were validated in this meta-analysis, the optimal proportion of CHRT-CHF in enhancing the efficacy may be 20–30%; Additionally, higher proportion (≥40%) of CHRT-CHF appears to reduce PES after TACE treatment. The potential role of combined relative proportion of CHRT-CHF with TACE should be emphasized in clinic.

Safety and efficacy of precision hepatectomy in the treatment of primary liver cancer

BackgroundThe aim of this study was to investigate the safety and efficacy of precision hepatectomy in the treatment of primary liver cancer.MethodsAn randomized controlled trial of 98 patients with primary liver cancer admitted to our hospital from February 2020 to February 2021 were analyzed for the study, and they were divided into 49 cases each in the control group (conventional hepatectomy) and the study group (precision hepatectomy) according to the different surgical methods. The surgical condition, complications and follow-up results of the two groups were counted, and the liver function and immune function of the two groups were observed before and 1 week after surgery.ResultsThe operation time, intraoperative bleeding, hospitalization time and anal venting time in the study group were less than those in the control group (P < 0.05). One week after surgery, AST, TBiL, ALT and ALB levels decreased, with in the study group significantly higher than those in the control group (P < 0.05); CD4+, CD3 + and CD4+/CD8 + levels were significantly higher in the study group (P < 0.05). The incidence of complications in the study group was significantly lower than that in the control group (P < 0.05). After 2 years of follow-up, the recurrence rate and mortality rate of the study group were lower than those of the control group (P < 0.05); the difference was not statistically significant when comparing the metastasis rate between the two groups (P > 0.05).ConclusionPrecision hepatectomy can effectively treat primary liver cancer with high safety and could be promoted in clinical practice.

Assessing the effectiveness of camrelizumab plus apatinib versus sorafenib for the treatment of primary liver cancer: a single-center retrospective study

Although the effectiveness of camrelizumab plus apatinib has been confirmed in a phase II clinical study, the efficacy of camrelizumab plus apatinib versus sorafenib for primary liver cancer (PLC) remains unverified. We retrospectively collected the data of 143 patients with PLC who received camrelizumab plus apatinib or sorafenib as the first-line treatment at The First Affiliated Hospital of Anhui Medical University from April 2018 to November 2021. Of these, 71 patients received an intravenous injection of camrelizumab 200 mg (body weight ≥ 50 kg) or 3 mg/kg (body weight < 50 kg) followed by an oral dosage of apatinib 250 mg/day every 3 weeks and 72 patients received sorafenib 400 mg orally, twice a day in 28-day cycles. The primary outcomes were overall survival and progression-free survival. The secondary outcomes were objective response rate, disease control rate, and safety. The median median progression-free survival and median overall survival with camrelizumab plus apatinib and sorafenib were 6.0 (95% confidence interval (CI) 4.2–7.8) and 3.0 months (95% CI 2.3–3.7) and 19.0 (95% CI 16.4–21.6) and 12.0 months (95% CI 8.9–15.1), respectively (death hazard ratio: 0.61, P = 0.023). Grade 3/4 treatment-related adverse events were noted in 50 (70.4%) patients in the camrelizumab plus apatinib group and 19 (26.4%) patients in the sorafenib group. Two treatment-related deaths were recorded. Clinically significant improvements were observed in overall survival and progression-free survival with camrelizumab plus apatinib versus sorafenib. Although the side effects of camrelizumab plus apatinib are relatively high, they can be controlled.

Traditional Chinese medicine combined with radiofrequency ablation improves primary liver cancer outcomes: A systematic review with meta-analysis

Background & aimsTraditional Chinese medicine and radiofrequency ablation are becoming increasingly important in the treatment of primary liver cancer. However, the clinical outcome of traditional Chinese medicine plus radiofrequency ablation is contentious. This study aimed to conduct a meta-analysis of randomized controlled clinical trials to address this gap. MethodsShort-term efficacy, alpha-fetoprotein level, immune function, liver function, and quality of life outcomes in patients with primary liver cancer treated with Chinese herbal medicine adjuvant radiofrequency ablation were systematically reviewed. ResultsEighteen randomized controlled clinical trials with 1488 patients with primary liver cancer were included. The combination treatment significantly increased the objective remission rate and quality of patient survival compared to the control group. Combination treatment significantly improved immunity and liver function factors, including CD3, CD4, CD4/CD8, alanine aminotransferase, aspartate aminotransferase, total bilirubin, and albumin levels. However, there were no statistical differences in CD8 levels across treatments. Trial sequential analysis showed that the cumulative Z-curve of the Objective response rate crossed the conventional and test sequence monitoring boundaries; however, it did not cross the required information size line. ConclusionsTraditional Chinese medicine combined with radiofrequency ablation for primary liver cancer can effectively reduce alpha-fetoprotein and improve clinical efficacy, immune function, liver function, as well as the quality of life.

Enhancing NKT cell-mediated immunity against hepatocellular carcinoma: Role of XYXD in promoting primary bile acid synthesis and improving gut microbiota

Ethnopharmacological relevance‘Xiayuxue decoction’ (XYXD) is a traditional Chinese medicine compound, composing of three natural medicines: Rheum officinale Baill., Prunus persica (L.) Batsch and Eupolyphaga sinensis Walker. It is derived from the famous traditional Chinese medical classics ‘Jingui Yaolue’ and has been used for thousands of years. In the Guidelines for the Diagnosis and Treatment of Primary liver Cancer issued by China's Health Commission, XYXD was applied in the treatment of primary liver cancer. Aim of the studyTo clarify the pharmacodynamic material basis and mechanism of XYXD in the treatment of hepatocellular carcinoma (HCC). Materials and methodsFirstly, the active components of XYXD and its distribution in vivo were identified by Ultraperformance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Then, the effective components and mechanism of XYXD against HCC were explored by network pharmacology combined with cell experiments in vitro. Furthermore, the anti-HCC effect of XYXD was determined by animal experiments in vivo. Metagenomic sequencing was used to detect its effect in gut microbiota, and targeted metabolism was used to detect the changes of bile acids in the liver. Finally, the related targets of NKT cell immune function activation were detected by RT-qPCR and Elisa. ResultsA total of 113 active ingredients in XYXD were identified, and the distribution of active ingredients in blood, liver, tumor, cecum, intestinal contents and feces was clarified. The circulation process and active ingredient group of XYXD were preliminarily clarified. In addition, we found five anti-HCC active ingredients in XYXD through network pharmacology combined with cell experiments in vitro, among which aloe emodin had the most significant effect, and predicted the potential mechanism of XYXD against HCC through NKT cell pathway. Moreover, the inhibitory effect of XYXD on liver tumor growth was clarified by animal experiments in vivo. The mechanism was mainly to promote the production of bile salt hydrolase (BSH) by increasing the abundance of Bacteroides and Lactobacillus, BSH converts conjugated bile acids into primary bile acids, and reduces the conversion of primary bile acids to secondary bile acids by reducing the abundance of Eubacterium, thereby increasing the content of primary bile acids. Primary bile acids trigger NKT cells in the liver to produce interferon-γ to exert anti-HCC immune effects. ConclusionThis study found that the traditional Chinese herbal formula XYXD can trigger the immune effect of NKT cells against HCC by regulating the interaction between gut microbiota and bile acids.

Efficacy and safety of different PD-1 inhibitors in combination with lenvatinib in the treatment of unresectable primary liver cancer: a multicentre retrospective study

Immune checkpoint inhibitors (ICIs) are safe and efficacious treatments for advanced primary liver cancer (PLC). The efficacy of different ICIs in the treatment of liver cancer remains unclear. The purpose of this study was to explore whether there is a difference in the efficacy and safety of various programmed cell death protein 1 (PD-1) inhibitors in combination with lenvatinib in the treatment of unresectable PLC. Patients with PLC treated with lenvatinib in combination with PD-1 inhibitors (camrelizumab, tislelizumab, sintilimab, or pembrolizumab) between January 2018 and December 2021 were retrospectively enrolled. Tumor response, adverse events, and grades were evaluated. Kaplan–Meier analysis and log-rank test were used to compare the overall survival and progression-free survival of patients treated with different PD-1 inhibitors. Cox regression analysis was used for univariate and multivariate analyses to identify clinical variables related to treatment efficacy. This study included a total of 176 patients who received a combination of lenvatinib and PD-1 inhibitors. Of these, 103 patients received camrelizumab, 44 received tislelizumab, 20 received sintilimab, and 9 received pembrolizumab. There was no significant difference in the pairwise comparison of camrelizumab, tislelizumab, sintilimab, and pembrolizumab using Kaplan–Meier survival analysis. Adverse events occurred in 40 (22.7%) patients (grade ≥ 3, 2.3%). The incidence of grade 3 adverse events among the four PD-1 inhibitor groups was below 5%. Camrelizumab, tislelizumab, sintilimab, and pembrolizumab are viable options for patients with unresectable PLC. These PD-1 inhibitors in combination with lenvatinib showed good safety profiles. The results guide selecting treatment for patients with unresectable PLC.

Liver organoids: a promising three-dimensional model for insights and innovations in tumor progression and precision medicine of liver cancer.

Primary liver cancer (PLC) is one type of cancer with high incidence rate and high mortality rate in the worldwide. Systemic therapy is the major treatment for PLC, including surgical resection, immunotherapy and targeted therapy. However, mainly due to the heterogeneity of tumors, responses to the above drug therapy differ from person to person, indicating the urgent needs for personalized treatment for PLC. Organoids are 3D models derived from adult liver tissues or pluripotent stem cells. Based on the ability to recapitulate the genetic and functional features of in vivo tissues, organoids have assisted biomedical research to make tremendous progress in understanding disease origin, progression and treatment strategies since their invention and application. In liver cancer research, liver organoids contribute greatly to reflecting the heterogeneity of liver cancer and restoring tumor microenvironment (TME) by co-organizing tumor vasculature and stromal components in vitro. Therefore, they provide a promising platform for further investigation into the biology of liver cancer, drug screening and precision medicine for PLC. In this review, we discuss the recent advances of liver organoids in liver cancer, in terms of generation methods, application in precision medicine and TME modeling.

Chinese expert consensus on CT-guided thermal ablation treatment of primary liver cancer

In order to standardize CT-guided local ablation as treatment of liver cancer in China, integrate advanced concepts of "precision medicine", adopt the image guided thermal ablation (IGTA) technique, and improve multidisciplinary approach in the treatment of liver cancer, experts from the Society of Tumor Ablation Therapy of the Chinese Anti-Cancer Association, the Ablation Expert Committee of the Chinese Society of Clinical Oncology (CSCO), and the Expert Group on Tumor Ablation Therapy of the Chinese Medical Doctors, discussed and developed a consensus on CT-guided percutaneous thermal ablation therapy for primary liver cancer, based on current treatment guidelines in ablation therapy. This was an attempt to standardize and develop clinical practice related to CT-guided thermal ablation treatment in patients with primary liver cancer.

The intervention effect of Aitongxiao prescription on primary liver cancer rats was evaluated based on high-throughput miRNA sequencing and bioinformatics analysis.

Liver cancer is a common malignant tumor known for its difficult treatment and poor prognosis. As a traditional Chinese medicine prescription, Aitongxiao prescription (ATXP) has been used in clinical treatment of primary liver cancer (PLC) for more than ten years, and its therapeutic effect is obvious and has been verified over time. However, the mechanism of ATXP in treating PLC has not been fully elucidated. This study aimed to detect the liver-protective effect of ATXP on a PLC rat model and explore its potential mechanism from the perspective of plasma extracellular vesicle miRNAs. Fifty SPF male SD rats were randomly selected, with six rats as the control group, and the remaining rats were injected with DEN to establish a primary liver cancer model. The model rats were randomly divided into the model group and the ATXP group. After 4 weeks of intervention, the liver-protective effect of ATXP was evaluated using plasma biochemical indicators and histopathological methods. Plasma extracellular vesicles were isolated and extracted, and identified by transmission electron microscopy, nanoparticle tracking analysis, and western blot. Significant differentially expressed miRNAs in extracellular vesicles were screened by Illumina sequencing to explore the therapeutic targets of ATXP and conduct functional analysis. The results showed that ATXP significantly reduced plasma liver function in PLC rats and alleviated liver pathological damage. In addition, plasma extracellular vesicles were isolated and identified. According to the results of GO and KEGG analysis, they were related to multiple biological processes and covered multiple signaling pathways (PI3K-Akt and MAPK signaling pathways, etc.). The interaction between miR-199a-3p and MAP3K4 was determined by bioinformatics methods and dual-luciferase reporter gene detection, confirming that MAP3K4 is the target gene of miR-199a-3p. In conclusion, ATXP protects the liver from DEN-induced PLC, which may be related to the regulation of plasma extracellular vesicle miR-199a-3p. This study further reveals the mechanism of ATXP in treating liver cancer and provides a theoretical basis for subsequent research.

Real-world 10-year retrospective study of the guidelines for diagnosis and treatment of primary liver cancer in China.

Hepatocellular carcinoma (HCC) is a common malignant tumor worldwide. Many regions across the world have issued various HCC diagnosis and treatment protocols to improve the diagnosis and targeted treatment of patients with HCC. However, real-world studies analysing the practice, application value, and existing problems of the China Liver Cancer (CNLC) staging system are scarce. To analyze the current situation and problems associated with the Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China. We collected the medical records of all patients with HCC admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2011 to December 31, 2019, and recorded the hospitalization information of those patients until December 31, 2020. All information on the diagnosis and treatment of the target patients was recorded, and their demographic and sociological characteristics, CNLC stages, screening situations, and treatment methods and effects were analyzed. The survival status of the patients was obtained from follow-up data. This study included the medical records of 3022 patients with HCC. Among these cases, 304 patients were screened before HCC diagnosis; their early-stage diagnosis rate was 69.08%, which was significantly higher than that of patients with HCC who were diagnosed without screening and early detection (33.74%). Herein, patients with no clinical outcome at discharge were followed up, and the survival information of 1128 patients was obtained. A Cox model was used to analyse independent risk factors affecting overall survival, which were revealed as age > 50 years, no screening, alpha-fetoprotein > 400 ng/mL, Child-Pugh grade B, and middle and late CNLC stages. Based on the Cox model survival analysis, in our study, patients with HCC identified via screening had significant advantages in overall and tumor-free survival after hepatectomy. Early diagnosis and treatment can be achieved by screening groups at high risk for HCC based on the guidelines; however, real-world compliance is poor.

Surgical management of primary liver cancers during the COVID-19 pandemic: overcoming the dilemma with standardization

BackgroundThe present study evaluates the impact of the pandemic on outcomes after surgical treatment for primary liver cancer in a high-volume hepatopancreatobiliary surgery center. MethodsPatients, who underwent liver resection for primary liver resection between January 2019 and February 2020, comprised pre-pandemic control group. The pandemic period was divided into two timeframes: early pandemic (March 2020–January 2021) and late pandemic (February 2021–December 2021). Liver resections during 2022 were considered as the post-pandemic period. Peri-, and postoperative patient data were gathered from a prospectively maintained database. ResultsTwo-hundred-eighty-one patients underwent liver resection for primary liver cancer. The number of procedures decreased by 37.1% during early phase of pandemic, but then increased by 66.7% during late phase, which was comparable to post-pandemic phase. Postoperative outcomes were similar between four phases. The duration of hospital stay was longer during the late phase, but not significantly different compared to other groups. ConclusionDespite an initial reduction in number of surgeries, COVID-19 pandemic had no negative effect on outcomes of surgical treatment for primary liver cancer. The structured standard operating protocol in a high-volume and highly specialized surgical center can withstand negative effects, a pandemic may have on treatment of patients.

Complications of Transcatheter Arterial Chemoembolization for Treatment of Primary Liver Cancer

AbstractTranscatheter arterial chemoembolization (TACE) is the standard practice in treating both primary and metastatic liver neoplasms. TACE is a practical, minimally invasive procedure involving the delivery of chemotherapeutic agents into the artery supplying a tumor while simultaneously embolizing its blood supply. This approach can be used for curative and palliative intent across multiple cancer types. Historically, TACE has been instrumental in the treatment algorithms for hepatocellular carcinoma, allowing patients with unresectable disease to be downstaged and to slow disease progression, affording opportunities for transplantation and increased survival. Although benefits of TACE include lower morbidity and mortality versus systemic chemotherapy and surgical approaches, the procedure has risks and complications. Interventional radiologists and physicians involved in the care of these patients should be aware of the associated complications including avoidance and treatment strategies.

Analysis of the intestinal flora in patients with primary liver cancer*

Abstract Objective To investigate the differences in intestinal flora of patients with primary liver cancer and of healthy individuals and to investigate the effect of the differential flora on the development of liver cancer. Methods Overall, 67 patients with primary liver cancer who received systematic and complete treatment between January 2019 and December 2020 at the Sixth People’s Hospital of Qingdao and had complete clinical data were enrolled in this study, and 26 individuals who were healthy on physical examination in the same period were used as healthy controls. Macro genome and 16s ribosome Deoxyribo Nucleic Acid (rDNA) high-throughput sequencing were performed on the stool flora of the enrolled patients and controls, and the differences in the intestinal flora were analyzed using the LEfSe bioinformatics software. Results Compared with the control samples, all the tested patient samples showed statistically significant differences in the number of colonies of 5 bacterial phyla, 5 orders, 8 families, 11 genera, and 14 species (P &lt; 0.05). Conclusion Compared with healthy people, patients with primary liver cancer have significant differences in the intestinal flora composition. The alteration of the intestinal flora may be correlated with the occurrence of primary liver cancer, and the intestinal flora may become a novel target for the prevention and treatment of primary liver cancer.

The Emerging Role of Tumor Microenvironmental Stimuli in Regulating Metabolic Rewiring of Liver Cancer Stem Cells

Primary liver cancer (PLC) is one of the most devastating cancers worldwide. Extensive phenotypical and functional heterogeneity is a cardinal hallmark of cancer, including PLC, and is related to the cancer stem cell (CSC) concept. CSCs are responsible for tumor growth, progression, relapse and resistance to conventional therapies. Metabolic reprogramming represents an emerging hallmark of cancer. Cancer cells, including CSCs, are very plastic and possess the dynamic ability to constantly shift between different metabolic states depending on various intrinsic and extrinsic stimuli, therefore amplifying the complexity of understanding tumor heterogeneity. Besides the well-known Warburg effect, several other metabolic pathways including lipids and iron metabolism are altered in PLC. An increasing number of studies supports the role of the surrounding tumor microenvironment (TME) in the metabolic control of liver CSCs. In this review, we discuss the complex metabolic rewiring affecting liver cancer cells and, in particular, liver CSCs. Moreover, we highlight the role of TME cellular and noncellular components in regulating liver CSC metabolic plasticity. Deciphering the specific mechanisms regulating liver CSC-TME metabolic interplay could be very helpful with respect to the development of more effective and innovative combinatorial therapies for PLC treatment.

Impact of treatment-duration-ratio of traditional Chinese medicine on survival period of primary liver cancer —A real-world study

IntroductionIn China, traditional Chinese medicine (TCM) is regarded as an effective treatment for primary liver cancer (PLC). The present study analyzed the effect of TCM on the survival period of patients with PLC by analyzing the relationship between the treatment-duration-ratio of traditional Chinese medicine (C-TDR, (traditional Chinese medicine treatment duration)/(Overall treatment duration) × 100%) and the survival time of 1002 patients with PLC. MethodsIn this study, 1002 patients with PLC admitted to TCM Oncology Department of Changhai Hospital from January, 2015 to December, 2019 were enrolled. The univariate and multivariate Cox regression equation, propensity score matching (PSM) were performed to identify independent prognostic factors for survival outcomes of PLC patients at different stages and estimate the influence of C-TDR on survival time. ResultsCox regression analysis indicated that C-TDR was an independent prognostic factor for survival outcome (P＜0.05) and a corresponding reduction of relative risk of death of 75.67% (relative risk (RR) = 0.2433; 95%Confedential Interval (CI) = 0.1747–0.3388). Similarly, it is also an independent prognostic factor for patients outcome of each stage (P＜0.05). The 251 patients of BCLC-A reduced 96.09% risk of mortality (RR = 0.0391; 95%CI = 0.0151–0.1012). The 396 BCLC-B patients decreased risk of death of 81.24% (RR = 0.1876, 95%CI = 0.1112–0.3163). Moreover, 355 patients of stage C demonstrated a 51.36% lower risk of death (RR = 1.0016, 95%CI = 0.9885–1.0149). Significant differences were found in the median overall survival (OS) both higher and lower C-TDR of all patients. Even after PSM, the overall survival of two groups were significantly improved following each stage. ConclusionEarlier administration of traditional Chinese medicine can reduce the risk of mortality and prolong survival in patients with liver cancer.

The role of tumor microenvironment reprogramming in primary liver cancer chemotherapy resistance.

Primary liver cancer (PLC), including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), and other rare tumours, is the second leading cause of cancer-related mortality. It has been a major contributor to the cancer burden worldwide. Of all primary liver cancer, HCC is the most common type. Over the past few decades, chemotherapy, immunotherapy and other therapies have been identified as applicable to the treatment of HCC. However, evidence suggests that chemotherapy resistance is associated with higher mortality rates in liver cancer. The tumour microenvironment (TME), which includes molecular, cellular, extracellular matrix(ECM), and vascular signalling pathways, is a complex ecosystem. It is now increasingly recognized that the tumour microenvironment plays a pivotal role in PLC prognosis, progression and treatment response. Cancer cells reprogram the tumour microenvironment to develop resistance to chemotherapy drugs distinct from normal differentiated tissues. Chemotherapy resistance mechanisms are reshaped during TME reprogramming. For this reason, TME reprogramming can provide a powerful tool to understand better both cancer-fate processes and regenerative, with the potential to develop a new treatment. This review discusses the recent progress of tumour drug resistance, particularly tumour microenvironment reprogramming in tumour chemotherapy resistance, and focuses on its potential application prospects.
