Irreversible electroporation for metastatic pancreatic carcinoma with liver metastasis:What does the evidence say

Irreversible electroporation is a promising non-thermal ablation method that has been shown to increase overall survival in locally advanced pancreatic cancer in some studies.However,higher quality studies with proper controls and randomization are required to establish its superiority when added with neoadjuvant chemotherapy over the current management of choice,which is chemotherapy alone.Further studies are required before establishment of any survival benefit in metastatic pancreatic carcinoma,and such evidence is lacking at present.

Downstaging strategies for unresectable hepatocellular carcinoma

A significant number of patients with hepatocellular carcinoma(HCC)are usually diagnosed in advanced stages,that leads to inability to achieve cure.Palliative options are focusing on downstaging a locally advanced disease.It is wellsupported in the literature that patients with HCC who undergo successful conversion therapy followed by curative-intent surgery may achieve a significant survival benefit compared to those who receive chemotherapy alone or those who are successfully downstaged with conversion therapy but not treated with surgery.Hepatic artery infusion chemotherapy can be a potential downstaging strategy,since recent studies have demonstrated excellent outcomes in patients with colorectal liver metastatic disease as well as primary liver malignancies.

Conversion therapy for unresectable hepatocellular carcinoma:Advances and challenges

Recently,the World Journal of Gastrointestinal Oncology published an article entitled“Pathologically successful conversion hepatectomy for advanced giant hepatocellular carcinoma after multidisciplinary therapy:A case report and review of the literature”,in which the authors shared their successful experience with complete surgical resection after multidisciplinary conversion therapy.The study by Chu et al demonstrates the great challenges that the advanced hepatocellular carcinoma(HCC)poses to surgical oncology,reveals the complexity of conversion therapy for unresectable HCC,emphasizes the important role of a multidisciplinary management model in conversion therapy,and enriches our understanding of the dynamics of personalized treatment for different patients.At present,conversion therapy is a hot research topic in the treatment of unresectable HCC,which has brought new hope to many patients with moderately advanced HCC.However,there are still many urgent problems to be solved in conversion therapy.Here,we would like to further discuss the advances and challenges of conversion therapy for unresectable HCC with the authors and the general readers.

Endobronchial metastasis secondary to renal clear cell carcinoma:A case report

BACKGROUND Endobronchial metastases(EBMs)are tumours that metastasise from a malignant tumour outside the lungs to the central and subsegmental bronchi,and are visible under a bronchofibrescope.Most EBMs are formed by direct invasion or metastasis of intrathoracic malignant tumours,such as lung cancer,oesophageal cancer or mediastinum tumours.Renal cell carcinoma(RCC),accounting for 2%to 3%of all tumours,is a common malignant tumour of the urinary system.Renal clear cell carcinoma(RCCC)constitutes the predominant pathological subtype of RCC,comprising approximately 70%to 80%of all RCC cases.RCCC can spread and metastasise through arterial,venous and lymphatic circulation to almost all organs of the body.Moreover,lung,bone,liver,brain and local recurrence are the most common metastatic neoplasms of RCCC.However,EBM from RCCC has a low complication rate and is often misdiagnosed as primary lung cancer.CASE SUMMARY A 71-year-old male patient who had undergone radical left nephrectomy 7 years prior due to RCCC was referred to our hospital due to a 1-mo history of productive cough.The results of an enhanced chest CT scan indicated the presence of a soft tissue nodule in the upper lobe of the left lung,and flexible bronchoscopy revealed a hypervascular lesion in the bronchus of the left lung's superior lobe.Therefore,the patient underwent thoracoscopic left superior lobe wedge resection,and pathology confirmed EBM from the RCCC.CONCLUSION EBM from RCCC has a low incidence and no characteristic clinical manifestations in the early stage.If a bronchial tumour is found in a patient with RCCC,the possibility of bronchial metastatic cancer should be considered.

Cetuximab combined with chemotherapy for simultaneous esophageal squamous cell carcinoma and colon adenocarcinoma:A case report

BACKGROUND Multiple primary carcinomas(MPCs)are defined as two or more independent primary cancers that occur simultaneously or sequentially in the same individual.Synchronous MPCs are rarer than solitary cancers or metachronous MPCs.Accurate diagnoses of synchronous MPCs and the choice of treatment are critical for successful outcomes in these cases.CASE SUMMARY A 64-year-old patient presented with dysphagia,without obvious cause.A diagnosis of synchronous esophageal squamous cell carcinoma and colon adenocarcinoma with liver metastasis was confirmed based on examination and laboratory results.After multi-disciplinary consultations,combination chemotherapy(a 3-wk cycle with oxaliplatin 212 mg administered on day 1 and capecitabine 1.5 g twice daily on days 1-14)and esophageal cancer radiotherapy were initiated.Based on the results of genetic testing,we switched to a regimen of leucovorin+fluorouracil+oxaliplatin and cetuximab regimen for 8 cycles.Subsequently,capecitabine and bevacizumab were administered until the most recent follow-up,at which the tumor remained stable.CONCLUSION Successful cetuximab chemotherapy treatment provides a reference for the nonoperative and homogeneous treatment of different pathological types of synchronous MCPs.

Critical considerations for the management of gastrointestinal mixed neuroendocrine non-neuroendocrine neoplasms and pure neuroendocrine carcinomas

Mixed neuroendocrine non-neuroendocrine neoplasms constitute rare tumors that are located mainly in the gastrointestinal(GI)tract and have high degrees of malignancy,and the frequency of these tumors has been increasing.They consist of a neuroendocrine neoplastic component with another component of adenocarcinoma usually and have a dismal prognosis.The rare GI pure neuroendocrine carcinoma is highly aggressive and requires complex and extensive management since a genetic distinction exists between it and GI non-neuroendocrine neoplasms,which are generally slow-growing lesions.The most common GI-mixed neuroendocrine non-neuroendocrine neoplasms are colorectal,followed by gastric,mainly in the gastroesophageal junction.Current imaging modalities of nuclear medicine and radiology play important roles in the accuracy of diagnosis.Liquid biopsy may contribute to early detection and timely diagnosis.Ultrasonography,either endoscopic or abdominal,is a technique that contributes to a diagnosis;additionally,contrast-enhanced ultrasonography is very helpful in followup appointments.Histopathology establishes a definite diagnosis and stage by evaluating the cell differentiation grade and the cell proliferation index Ki67.The genetic profile can be valuable in diagnosis and gene therapy.Surgical resection with wide lymphadenectomy,whenever possible,and adjuvant chemotherapy constitute the main therapeutic management strategies.Targeted therapy and immunotherapy achieve encouraging results.

Liver-directed therapiesfor fibrolamellar carcinoma:Asingle-center experience

Background:This article aims to present the single-institution outcomes of patients with Fibrolamellar Carcinoma(FLC)treated with liver-directed therapies(LDT).Methods:In this single-center retrospective study,all patients diagnosed with FLC who underwent LDT were identified.Between July 2012 and July 2023,six patients were identified.One patient was excluded due to bleeding.Demographic and clinical parameters were recorded.Complications within 30 days of the LDT were evaluated.Radiological treatment responses at 1,6,and 12 months were assessed per mRECIST.Results:A total offive patients,which included three females and two males,were reviewed.Three patients were treated with transarterial hepatic embolization(TAE;n=3),transarterial radioembolization(TARE;n=1),and combined TAE+radiofrequency ablation(n=1).The objective response rate at one month was 80%[CR=2(40%),PR=2(40%),and SD=1(20%)].At 12 months(n=4),two patients demonstrated CR(50%)and two demonstrated PR(50%).Overall survival from LDT atfive years was 50%.There was no 30-day mortality among this group of patients or any adverse event attributable to the LDT.Conclusion:TAE,TARE,and ablation are safe and effective therapeutic options for FLC.Based on this study and previously published case reports,ablation and TARE yielded the most favorable results.

An overview of the contemporary diagnosis and management approaches for anaplastic thyroid carcinoma

Thyroid carcinoma is a complex disease with several types,the most common being well-differentiated and undifferentiated.The latter,“undifferentiated carcinoma”,also known as anaplastic thyroid carcinoma(ATC),is a highly aggr-essive malignant tumor accounting for less than 0.2%of all thyroid carcinomas and carries a poor prognosis with a median survival of 5 months.BRAF gene mutations are the most common molecular factor associated with this type of thyroid carcinoma.Recent advances in targeted biological agents,immuno-therapy,stem cell therapy,nanotechnology,the dabrafenib/trametinib com-bination therapy,immune checkpoint inhibitors(ICI)and artificial intelligence offer novel treatment options.The combination therapy of dabrafenib and tra-metinib is the current standard treatment for patients with BRAF-V600E gene mutations.Besides,the dabrafenib/trametinib combination therapy,ICI,used alone or in combination with targeted therapies have raised some hopes for improving the prognosis of this deadly disease.Younger age,earlier tumor stage and radiotherapy are all prognostic factors for improved outcomes.Ultimately,therapeutic regimens should be tailored to the individual patient based on surveillance and epidemiological data,and a multidisciplinary approach is ess-ential.

Classificatory updates in verrucous and cuniculatum carcinomas:Insights from the 5^(th) edition of WHO-IARC head and neck tumor classification

The International Agency for Research on Cancer(IARC)and World Health Organization(WHO)collaboratively produce the'WHO Blue Books'essential tools standardizing the diagnostic process for human cancers.Regular updates in this classification accommodate emerging molecular discoveries,advances in immunohistochemical techniques,and evolving clinical insights.The 5th edition of the WHO/IARC classification of head and neck tumors refines the'Oral Cavity and Mobile Tongue'chapter,including sections for non-neoplastic lesions,epithelial tumors,and tumors of uncertain histogenesis.Notably,the epithelial tumors section is rearranged by tumor behavior,starting with benign squamous papillomas and progressing through potentially malignant oral disorders to oral squamous cell carcinoma(OSCC).The section on OSCC reflects recent information on epidemiology,pathogenesis,and histological prognostic factors.Noteworthy is the specific categorization of verrucous carcinoma(VC)and carcinoma cuniculatum(CC),both associated with the oral cavity and distinct in clinical and histologic characteristics.This classification adjustment emphasizes the oral cavity as their predominant site in the head and neck.Designating specific sections for VC and CC aims to provide comprehensive insights into these unique subtypes,elucidating their clinical features,distinct histological characteristics,prevalence,significance,and clinical relevance.By categorizing these subtypes into specific sections,the 5th edition of the WHO classification aims to provide a more nuanced and detailed account,enhancing our understanding of these specific variants within the broader spectrum of head and neck tumors.

Comparative Analysis of Ki-67 Protein as a Proliferative Expression Index in Cutaneous Basal and Squamous Cell Carcinoma in Federal Medical Centre Umuahia, Nigeria

Background: Evaluating the tumor proliferative index helps predict clinical behavior and provides prognostic insights for cutaneous basal cell carcinoma (cBCC) and squamous cell carcinoma (cSCC). Objective: This study aimed to identify differences in the proliferative indices among variants of cBCC and cSCC diagnosed at a tertiary healthcare center. Method: Skin biopsies histologically diagnosed as cBCC and cSCC between 2012 and 2018 at the Federal Medical Centre (FMC) Umuahia, Abia State, Nigeria, were analyzed. Archival formalin-fixed, paraffin-embedded (FFPE) tissue blocks were retrieved along with clinical data, and were prepared on charged microscope slides and the immunohistochemical staining was carried out. The primary antibody used in this study was clone BioCare CRM325C (RM) and adenotonsillar tissue blocks/slides served as positive controls. Ki-67 immunohistochemistry was performed on fresh 4µm sections of the tumor specimens. Results: The application of Ki-67 immunoperoxidase on both BCC and SCC cohort, yielded an intense observable brownish nuclear stain in areas of dense proliferating tumour cells on both cutaneous tumours. The average Ki-67 index for all cSCC cases was 24.7%, with a range of 2.3% - 80%, while the mean for cBCC was 15.8%, ranging from 1.2% - 45.6%. Variants with high proliferative indices were observed in 11.9% of cBCC cases and 29.1% of cSCC cases. Among the low proliferative index category, cSCC accounted for 5.4%, while cBCC represented 14.3%. For mild proliferative indices, cSCC cases made up 7.3% and cBCC, 11.9%. The majority of cases showed moderate proliferative indices, with 61.9% for cBCC and 58.2% for cSCC. Overall, there was a significant difference in proliferative indices between cSCC, cBCC, and their variants. Conclusion: The study found a significantly higher rate of cell proliferation, measured by Ki-67 immunostaining, in cSCC and its variants compared to cBCC. However, certain variants of cBCC also exhibited high Ki-67 expression, indicating they can be as aggressive as some cSCC variants.

Hepatocellular carcinoma-the role of the underlying liver disease in clinical practice

Hepatocellular carcinoma(HCC)is one of the most common causes of cancerrelated mortality.This particular type of cancer has the distinctive characteristic of mostly happening in individuals with an underlying liver disease.This makes the management of patients more challenging,since physicians must take into consideration two different conditions,the chronic liver disease and the tumor.The underlying liver disease has several implications in clinical practice,because different kinds of chronic liver disease can lead to varying degrees of risk of developing HCC,obstacles in surveillance,and differences in the efficacy of the treatment against HCC.A shift in the prevalence of liver diseases has been evident over the last few years,with viral hepatitis gradually losing the leading position as cause of HCC and metabolic dysfunction-associated steatotic liver disease gaining importance.Therefore,in an era of personalized medicine,it is imperative that physicians are aware of the underlying liver disease of individuals with HCC and its impact in the management of their tumors.

Present and future of new systemic therapies for early and intermediate stages of hepatocellular carcinoma

Hepatocellular carcinoma(HCC)is a high mortality neoplasm which usually appears on a cirrhotic liver.The therapeutic arsenal and subsequent prognostic outlook are intrinsically linked to the HCC stage at diagnosis.Notwithstanding the current deployment of treatments with curative intent(liver resection/local ablation and liver transplantation)in early and intermediate stages,a high rate of HCC recurrence persists,underscoring a pivotal clinical challenge.Emergent systemic therapies(ST),particularly immunotherapy,have demonstrate promising outcomes in terms of increase overall survival,but they are currently bound to the advanced stage of HCC.This review provides a comprehensive analysis of the literature,encompassing studies up to March 10,2024,evaluating the impact of novel ST in the early and intermediate HCC stages,specially focusing on the findings of neoadjuvant and adjuvant regimens,aimed at increasing significantly overall survival and recurrence-free survival after a treatment with curative intent.We also investigate the potential role of ST in enhancing the downstaging rate for the intermediate-stage HCC initially deemed ineligible for treatment with curative intent.Finally,we critically discuss about the current relevance of the results of these studies and the encouraging future implications of ST in the treatment schedules of early and intermediate HCC stages.

Treatment of lacrimal gland adenoid cystic carcinoma:a systematic review and Meta-analysis

AIM:To evaluate lacrimal gland adenoid cystic carcinoma(LGACC)of prognosis in patients who underwent different treatment regimens.METHODS:We searched PubMed,EMBASE,and the Cochrane Library for studies done on the treatment of LGACC,between January 1987 and April 2022.A Metaanalysis was conducted to pool the 5-year overall survival rate(OR),and the 5-year recurrence rate(RR)and 5-year metastasis rate(MR)were assessed.RESULTS:The 30 studies involved 585 patients were included in the Meta-analysis.The pooled 5-year OR with surgery alone was 50%,the 5-year RR was 63%,and the 5-year MR was 34%.The pooled 5-year OR with surgery and adjuvant radiotherapy combined was 67%(95%CI 61%,73%),the 5-year RR was 41%,and the 5-year MR was 35%.The pooled 5-year OR with surgery and adjuvant chemoradiotherapy combined was 72%(95%CI 59%,84%),the 5-year RR was 48%,and the 5-year MR was 36%.The pooled 5-year OR with surgery,intra-arterial cytoreductive chemotherapy,and adjuvant chemoradiotherapy combined was 78%(95%CI 68%,89%),the 5-year RR was 15%,and the 5-year MR was 27%.CONCLUSION:Comprehensive treatment is more effective than surgery alone.Surgery combined with intraarterial chemotherapy and adjuvant chemoradiotherapy seems to add value to the therapeutic effect of comprehensive treatment of LGACC but further high-quality research is required to validate this.

Adjuvant therapy for hepatocellular carcinoma:Dilemmas at the start of a new era

Approximately 50%-70%of patients with hepatocellular carcinoma experience recurrence within five years after curative hepatic resection or ablation.As a result,many patients receive adjuvant therapy after curative resection or ablation in order to prolong recurrence-free survival.The therapy recommended by national guidelines can differ,and guidelines do not specify when to initiate adjuvant therapy or how long to continue it.These and other unanswered questions around adjuvant therapies make it difficult to optimize them and determine which may be more appropriate for a given type of patient.These questions need to be addressed by clinicians and researchers.

A Deep Learning Approach for Forecasting Thunderstorm Gusts in the Beijing–Tianjin–Hebei Region

Thunderstorm gusts are a common form of severe convective weather in the warm season in North China,and it is of great importance to correctly forecast them.At present,the forecasting of thunderstorm gusts is mainly based on traditional subjective methods,which fails to achieve high-resolution and high-frequency gridded forecasts based on multiple observation sources.In this paper,we propose a deep learning method called Thunderstorm Gusts TransU-net(TGTransUnet)to forecast thunderstorm gusts in North China based on multi-source gridded product data from the Institute of Urban Meteorology(IUM)with a lead time of 1 to 6 h.To determine the specific range of thunderstorm gusts,we combine three meteorological variables:radar reflectivity factor,lightning location,and 1-h maximum instantaneous wind speed from automatic weather stations(AWSs),and obtain a reasonable ground truth of thunderstorm gusts.Then,we transform the forecasting problem into an image-to-image problem in deep learning under the TG-TransUnet architecture,which is based on convolutional neural networks and a transformer.The analysis and forecast data of the enriched multi-source gridded comprehensive forecasting system for the period 2021–23 are then used as training,validation,and testing datasets.Finally,the performance of TG-TransUnet is compared with other methods.The results show that TG-TransUnet has the best prediction results at 1–6 h.The IUM is currently using this model to support the forecasting of thunderstorm gusts in North China.

Enhancing Deep Learning Soil Moisture Forecasting Models by Integrating Physics-based Models

Accurate soil moisture(SM)prediction is critical for understanding hydrological processes.Physics-based(PB)models exhibit large uncertainties in SM predictions arising from uncertain parameterizations and insufficient representation of land-surface processes.In addition to PB models,deep learning(DL)models have been widely used in SM predictions recently.However,few pure DL models have notably high success rates due to lacking physical information.Thus,we developed hybrid models to effectively integrate the outputs of PB models into DL models to improve SM predictions.To this end,we first developed a hybrid model based on the attention mechanism to take advantage of PB models at each forecast time scale(attention model).We further built an ensemble model that combined the advantages of different hybrid schemes(ensemble model).We utilized SM forecasts from the Global Forecast System to enhance the convolutional long short-term memory(ConvLSTM)model for 1–16 days of SM predictions.The performances of the proposed hybrid models were investigated and compared with two existing hybrid models.The results showed that the attention model could leverage benefits of PB models and achieved the best predictability of drought events among the different hybrid models.Moreover,the ensemble model performed best among all hybrid models at all forecast time scales and different soil conditions.It is highlighted that the ensemble model outperformed the pure DL model over 79.5%of in situ stations for 16-day predictions.These findings suggest that our proposed hybrid models can adequately exploit the benefits of PB model outputs to aid DL models in making SM predictions.

Efficacy and predictive factors of transarterial chemoembolization combined with lenvatinib plus programmed cell death protein-1 inhibition for unresectable hepatocellular carcinoma

BACKGROUND The efficacy and safety of transarterial chemoembolization(TACE)combined with lenvatinib plus programmed cell death protein-1(PD-1)for unresectable hepato-cellular carcinoma(HCC)have rarely been evaluated and it is unknown which factors are related to efficacy.AIM To evaluate the efficacy and independent predictive factors of TACE combined with lenvatinib plus PD-1 inhibitors for unresectable HCC.METHODS This study retrospectively enrolled patients with unresectable HCC who received TACE/lenvatinib/PD-1 treatment between March 2019 and April 2022.Overall survival(OS)and progression-free survival(PFS)were determined.The objective response rate(ORR)and disease control rate(DCR)were evaluated in accordance with the modified Response Evaluation Criteria in Solid Tumors.Additionally,the prognostic factors affecting the clinical outcome were assessed.RESULTS One hundred and two patients were enrolled with a median follow-up duration of 12.63 months.The median OS was 26.43 months(95%CI:17.00-35.87),and the median PFS was 10.07 months(95%CI:8.50-11.65).The ORR and DCR were 61.76%and 81.37%,respectively.The patients with Barcelona Clinic Liver Cancer Classification(BCLC)B stage,early neutrophil-to-lymphocyte ratio(NLR)response(decrease),or early alpha-fetoprotein(AFP)response(decrease>20%)had superior OS and PFS than their counterparts.CONCLUSION This study showed that TACE/lenvatinib/PD-1 treatment was well tolerated with encouraging efficacy in patients with unresectable HCC.The patients with BCLC B-stage disease with early NLR response(decrease)and early AFP response(decrease>20%)may achieve better clinical outcomes with this triple therapy.

Telomerase-related advances in hepatocellular carcinoma:A bibliometric and visual analysis

BACKGROUND As a critical early event in hepatocellular carcinogenesis,telomerase activation might be a promising and critical biomarker for hepatocellular carcinoma(HCC)patients,and its function in the genesis and treatment of HCC has gained much attention over the past two decades.AIM To perform a bibliometric analysis to systematically assess the current state of research on HCC-related telomerase.METHODS The Web of Science Core Collection and PubMed were systematically searched to retrieve publications pertaining to HCC/telomerase limited to“articles”and“reviews”published in English.A total of 873 relevant publications related to HCC and telomerase were identified.We employed the Bibliometrix package in R to extract and analyze the fundamental information of the publications,such as the trends in the publications,citation counts,most prolific or influential writers,and most popular journals;to screen for keywords occurring at high frequency;and to draw collaboration and cluster analysis charts on the basis of coauthorship and co-occurrences.VOSviewer was utilized to compile and visualize the bibliometric data.RESULTS A surge of 51 publications on HCC/telomerase research occurred in 2016,the most productive year from 1996 to 2023,accompanied by the peak citation count recorded in 2016.Up to December 2023,35226 citations were made to all publications,an average of 46.6 citations to each paper.The United States received the most citations(n=13531),followed by China(n=7427)and Japan(n=5754).In terms of national cooperation,China presented the highest centrality,its strongest bonds being to the United States and Japan.Among the 20 academic institutions with the most publications,ten came from China and the rest of Asia,though the University of Paris Cité,Public Assistance-Hospitals of Paris,and the National Institute of Health and Medical Research(INSERM)were the most prolific.As for individual contributions,Hisatomi H,Kaneko S,and Ide T were the three most prolific authors.Kaneko S ranked first by H-index,G-index,and overall publication count,while Zucman-Rossi J ranked first in citation count.The five most popular journals were the World Journal of Gastroenterology,Hepatology,Journal of Hepatology,Oncotarget,and Oncogene,while Nature Genetics,Hepatology,and Nature Reviews Disease Primers had the most citations.We extracted 2293 keywords from the publications,120 of which appeared more than ten times.The most frequent were HCC,telomerase and human telomerase reverse transcriptase(hTERT).Keywords such as mutational landscape,TERT promoter mutations,landscape,risk,and prognosis were among the most common issues in this field in the last three years and may be topics for research in the coming years.CONCLUSION Our bibliometric analysis provides a comprehensive overview of HCC/telomerase research and insights into promising upcoming research.

Construction and validation of somatic mutation-derived long noncoding RNAs signatures of genomic instability to predict prognosis of hepatocellular carcinoma

BACKGROUND Long non-coding RNAs(LncRNAs)have been found to be a potential prognostic factor for cancers,including hepatocellular carcinoma(HCC).Some LncRNAs have been confirmed as potential indicators to quantify genomic instability(GI).Nevertheless,GI-LncRNAs remain largely unexplored.This study established a GI-derived LncRNA signature(GILncSig)that can predict the prognosis of HCC patients.AIM To establish a GILncSig that can predict the prognosis of HCC patients.METHODS Identification of GI-LncRNAs was conducted by combining LncRNA expression and somatic mutation profiles.The GI-LncRNAs were then analyzed for functional enrichment.The GILncSig was established in the training set by Cox regression analysis,and its predictive ability was verified in the testing set and TCGA set.In addition,we explored the effects of the GILncSig and TP53 on prognosis.RESULTS A total of 88 GI-LncRNAs were found,and functional enrichment analysis showed that their functions were mainly involved in small molecule metabolism and GI.The GILncSig was constructed by 5 LncRNAs(miR210HG,AC016735.1,AC116351.1,AC010643.1,LUCAT1).In the training set,the prognosis of high-risk patients was significantly worse than that of low-risk patients,and similar results were verified in the testing set and TCGA set.Multivariate Cox regression analysis and stratified analysis confirmed that the GILncSig could be used as an independent prognostic factor.Receiver operating characteristic curve analysis of the GILncSig showed that the area under the curve(0.773)was higher than the two LncRNA signatures published recently.Furthermore,the GILncSig may have a better predictive performance than TP53 mutation status alone.CONCLUSION We established a GILncSig that can predict the prognosis of HCC patients,which will help to guide prognostic evaluation and treatment decisions.

Leveraging machine learning for early recurrence prediction in hepatocellular carcinoma:A step towards precision medicine

The high rate of early recurrence in hepatocellular carcinoma(HCC)post curative surgical intervention poses a substantial clinical hurdle,impacting patient outcomes and complicating postoperative management.The advent of machine learning provides a unique opportunity to harness vast datasets,identifying subtle patterns and factors that elude conventional prognostic methods.Machine learning models,equipped with the ability to analyse intricate relationships within datasets,have shown promise in predicting outcomes in various medical disciplines.In the context of HCC,the application of machine learning to predict early recurrence holds potential for personalized postoperative care strategies.This editorial comments on the study carried out exploring the merits and efficacy of random survival forests(RSF)in identifying significant risk factors for recurrence,stratifying patients at low and high risk of HCC recurrence and comparing this to traditional COX proportional hazard models(CPH).In doing so,the study demonstrated that the RSF models are superior to traditional CPH models in predicting recurrence of HCC and represent a giant leap towards precision medicine.
