Donor-recipient race-ethnicity concordance and patient survival after liver transplantation.

INTRODUCTION: We assessed the association between patient survival after liver transplantation (LT) and donor-recipient race-ethnicity (R/E) concordance. METHODS: The Scientific Registry of Transplant Recipients (SRTR) was retrospectively analyzed using data collected between 2002 and 2019. Only adults without history of prior organ transplant and recipients of LT alone were included. The primary outcome was patient survival. Donors and recipients were categorized into five R/E groups: White/Caucasian, African American/Black, Hispanic/Latino, Asian, and Others. Statistical analyses were performed using Kaplan-Meier survival curves and Cox Proportional Hazards models, adjusting for donor and recipient covariates. RESULTS: 85,427 patients were included. Among all the R/E groups, Asian patients had the highest 5-year survival (81.3%; 95% CI = 79.9-82.7), while African American/Black patients had the lowest (71.4%; 95% CI = 70.3-72.6) (P < 0.001). Lower survival rates were observed in recipients who received discordant R/E grafts irrespective of their R/E group. The fully adjusted hazard ratio for death was statistically significant in African American/Black (aHR 1.07-1.18-1.31; P < 0.01) and in White∕Caucasian patients (aHR 1.00-1.04-1.07; P = 0.03) in the presence of donor-recipient R/E discordance. CONCLUSION: Disparities in post-LT outcomes might be influenced by biological factors in addition to well-known social determinants of health.

Interaction between cold ischemia time and Kidney Donor Profile Index on postrenal transplant outcomes.

We analyzed whether there is an interaction between the Kidney Donor Profile Index (KDPI) and cold ischemia time (CIT) in recipients of deceased donor kidney transplant (KTs). Adults who underwent KTs in the United States between 2014 and 2020 were included and divided into 3 KDPI groups (≤20%, 21%-85%, >85%) and 4 CIT strata (<12, 12-17.9, 18-23.9, ≥24 hours). Multivariate analyses were used to test the interaction between KDPI and CIT for the following outcomes: primary graft nonfunction (PGNF), delayed graft function (DGF), estimated glomerular filtration rate (eGFR) at 6 and 12 months, patient survival, graft survival, and death-censored graft survival (DCGS). A total of 69,490 recipients were analyzed: 18,241 (26.3%) received a graft with KDPI ≤20%, 46,953 (67.6%) with KDPI 21%-85%, and 4,296 (6.2%) with KDPI >85%. Increasing KDPI and CIT were associated with worse post-KT outcomes. Contrary to our hypothesis, howerver, the interaction between KDPI and CIT was statistically significant only for PGNF and DGF and eGFR at 6 months. Paradoxically, the negative coefficient of the interaction suggested that increasing duration of CIT was more detrimental for low and intermediate-KDPI organs relative to high-KDPI grafts. Conversely, for mortality, graft survival, and DCGS, we found that the interaction between CIT and KDPI was not statistically significant. We conclude that, high KDPI and prolonged CIT are independent risk factors for inferior outcomes after KT. Their interaction, however, is statistically significant only for the short-term outcomes and more pronounced on low and intermediate-KDPI grafts than high-KDPI kidneys.

Living donor liver transplantation for colorectal cancer liver metastases: Midterm outcomes at a single center in North America.

In recent years, liver transplantation has emerged as a treatment for patients with stage IV colorectal liver metastases (CRLM). Given the limited number of available deceased donor grafts, the use of living donor liver transplantation (LDLT) can be an important option. We performed a retrospective analysis of 10 patients that underwent LDLT for CRLM at our institution. A total of 90% of patients were male, with median age of 58 years and median model for end-stage liver disease score of 11 (range: 6-32). The rectum was the most common primary location (40%). Synchronous liver tumors were found in 50%. Pretransplant patients underwent resection (60%), hepatic-artery infusion pumping (50%), and/or radiofrequency ablation (50%). Everybody underwent adjuvant chemotherapy. Median cold ischemia time was 103 minutes (range: 93-207 minutes), and median total OR time was 11.5 hours (range: 8.5-13.9 hours). In total, 30% of patients had postoperative complications requiring reoperation. Mean recurrence-free survival was 2.2 years (95% confidence interval, 1.2-3.2 years), and mean overall survival was 3.0 years (95% confidence interval, 2.5-3.6 years). In total, 30% of patients suffered a recurrence, and 90% of patients are currently alive. This study represents the largest single-center analysis in North America of patients undergoing LDLT for CRLM. LDLT is a safe and effective alternative for patients with CRLM who do not have progressive disease or extrahepatic metastasis.

Safety of Patients with Renal Artery Aneurysm to Proceed with Living Donation.

BACKGROUND: Renal artery aneurysm (RAA) is a rare condition that involves dilation of all layers of the arterial wall of the renal artery. The risk of rupture is rare, but intervention is recommended for larger aneurysms. Surgical decision-making regarding live donor renal transplantation (LDRT) centers around safety for the living donor, and laterality of the donated kidney is based on providing the donor with the best longevity pertaining to the remaining kidney. We looked to review our long-term outcomes surrounding live donor transplants from donors with RAA with ex vivo resection and reconstruction prior to implantation. METHODS: A retrospective review was done of all laparoscopic live donor transplant nephrectomies with ex vivo aneurysm resection, reconstruction, and implantation at a single center. RESULTS: Three pairs of patients underwent successful laparoscopic donor nephrectomy, RAA resection, reconstruction, and transplantation of kidney. 2 males and 1 female ages 47 to 58 years of age underwent transplantation. The donors at 5 years of follow-up were noted to be functioning appropriately with no long-term sequelae of their donation and a mean remanent kidney function of 63 mL/min. DISCUSSION: For potential live donors with asymptomatic, unilateral renal artery aneurysm and no systemic disease, live donation with ex vivo resection and reconstruction can be performed with excellent long-term donor and recipient outcomes.

Incidence of hepatocellular carcinoma in nonalcoholic fatty liver disease without cirrhosis or advanced liver fibrosis.

BACKGROUND: HCC can develop in the absence of cirrhosis in patients with NAFLD. We aimed to estimate the incidence of HCC in patients with NAFLD with and without cirrhosis or advanced liver fibrosis. METHODS: We performed a cohort study to determine the incidence of HCC in patients with NAFLD identified by the International Classification of Diseases 9/10 codes in the electronic health records of a US health care system between 2004 and 2018. The incidence of HCC was stratified by the presence or absence of cirrhosis and by the Fibrosis-4 index (FIB-4) at the time of HCC diagnosis. RESULTS: Of 47,165 patients with NAFLD aged 40-89 years, 981 (2.1%) developed HCC (mean follow-up 3.4 y). Among patients with HCC, 842 (85.8%) had cirrhosis, while 139 (14.2%) did not. Of the 139 patients with HCC without cirrhosis-related diagnostic codes, 26 (2.7%) had FIB-4 >2.67 (advanced fibrosis likely), whereas 43 (4.4%) had FIB-4 < 1.30 (excluding advanced fibrosis). The annual incidence of HCC in patients with NAFLD with and without cirrhosis was 23.6 and 1.1 per 1000 person-years, respectively. Among patients without cirrhosis, the annual incidence of HCC was 2.8 per 1000 person-years with FIB-4 >2.67 and 0.7 per 1000 person-years with FIB-4 <1.30. Patients with NAFLD and cirrhosis were 31.8 times (95% CI, 23.3-43.4) more likely to develop HCC than those without cirrhosis and FIB-4 <1.30, after adjustment for age and sex. CONCLUSIONS: Patients with NAFLD without cirrhosis nor advanced fibrosis have a low incidence of HCC.

Textbook Outcomes After Open Live Donor Right Hepatectomy and Open Right Hepatic Lobectomy for Cancer in 686 patients: Redefining the Benchmark.

OBJECTIVE: To compare textbook outcomes (TO) of open live donor right hepatectomy (RH) versus open right hepatic lobectomy for cancer in a single Western center and to identify clinical factors associated with failure to achieve a TO. BACKGROUND: TO, a composite quality measure that captures multiple aspects of perioperative care, has not been thoroughly studied in open RH. We hypothesized that TO rates after RH for live donor transplant could represent the "best-achievable" results of this operation and could serve as the benchmark for RH performed for an oncologic indication. METHODS: A prospective database was reviewed to compare TO rates after RH for live donor purposes versus RH for cancer at a single center from 2010 to 2020. A TO was defined as achieving 7 metrics: no perioperative transfusion, no major postoperative complications, no significant bile leak, no unplanned transfer to the ICU, no 30-day mortality, no 30-day readmission, and no R1 margins for cancer cases. RESULTS: Among 686 RH patients (371 live donor and 315 cancer cases), a TO was achieved in 92.2% of RH donors and 53.7% of RH cancer cases. Live donor patients tended to be younger, healthier, and thinner. Among donors, increased intraoperative blood loss, and in cancer cases, male sex, tumor size, and increased intraoperative blood loss were associated with TO failure. CONCLUSIONS: A TO can be achieved in over 90% of patients undergoing living donor RH and in approximately half of RH cancer cases. These metrics represent a new benchmark for "real-world" TO after open RH.

Reversal of Roux-en-Y Gastric Bypass for Successful Salvage of Renal Allograft.

Enteric hyperoxaluria (EH) is a known complication of Roux-en-Y gastric bypass (RYGB) and can lead to nephrolithiasis, oxalate-induced nephropathy, and end-stage renal disease. Recurrent EH-induced renal impairment has been reported after kidney transplantation and may lead to allograft loss. EH occurs in up to one quarter of patients following malabsorption-based bariatric operations. We present a report of medically refractory EH in a renal transplant recipient with allograft dysfunction that was successfully managed with reversal of RYGB. The patient developed renal failure 7 years following gastric bypass requiring renal transplant. Following an uneventful living donor kidney transplant, the patient developed recurrent subacute allograft dysfunction. A diagnosis of oxalate nephropathy was made based on biopsy findings of renal tubular calcium oxalate deposition in conjunction with elevated serum oxalate levels and elevated 24-hr urinary oxalate excretion. Progressive renal failure ensued despite medical management. The patient underwent reversal of her RYGB, which resulted in recovery of allograft function. This report highlights an under-recognized, potentially treatable cause of renal allograft failure in patients with underlying gastrointestinal pathology or history of bariatric surgery and proposes a strategy for management of patients with persistent hyperoxaluria based on a review of the literature.

Poor Outcomes of Patients With NAFLD and Moderate Renal Dysfunction or Short-Term Dialysis Receiving a Liver Transplant Alone.

The outcomes of patients with moderate renal impairment and the impact of liver disease etiology on renal function recovery after liver transplant alone (LTA) are largely unknown. We explored whether NAFLD patients with pre-LTA moderate renal dysfunction (GFR 25-45 ml/min/1.73 m2) may be more susceptible to develop post-LTA severe renal dysfunction (GFR<15 ml/min/1.73 m2) than ALD patients, as well as other overall outcomes. Using the UNOS/OPTN database, we selected patients undergoing liver transplant for NAFLD or ALD (2006-2016), 15,103 of whom received LTA. NAFLD patients with moderate renal dysfunction were more likely to develop subsequent GFR<15 ml/min/1.73 m2 than ALD patients (11.1% vs. 7.38%, p < 0.001). Patients on short-term dialysis pre-LTA (≤12 weeks) were more likely to develop severe renal dysfunction (31.7% vs. 18.1%), especially in NAFLD patients, and were more likely to receive a further kidney transplant (15.3% vs. 3.7%) and had lower survival (48.6% vs. 50.4%) after LTA (p < 0.001 for all). NAFLD was an independent risk factor for post-LTA severe renal dysfunction (HR = 1.2, p = 0.02). NAFLD patients with moderate renal dysfunction and those receiving short-term dialysis prior to LTA are at a higher risk of developing subsequent severe renal dysfunction. Underlying etiology of liver disease may play a role in predicting development and progression of renal failure in patients receiving LTA.

Long-term immunological outcomes of early subclinical inflammation on surveillance kidney allograft biopsies.

The long-term impact of early subclinical inflammation (SCI) through surveillance biopsy has not been well studied. To do this, we recruited a prospective observational cohort that included 1000 sequential patients who received a kidney transplant from 2013-2017 at our center. A total of 586 patients who underwent a surveillance biopsy in their first year post-transplant were included after excluding those with clinical rejections, and those who were unable to undergo a surveillance biopsy. Patients were classified based on their biopsy findings: 282 with NSI (No Significant Inflammation) and 304 with SCI-T (SCI and Tubulitis) which was further subdivided into 182 with SC-BLR (Subclinical Borderline Changes) and 122 with SC-TCMR (Subclinical T Cell Mediated Rejection, Banff 2019 classification of 1A or more). We followed the clinical and immunological events including Clinical Biopsy Proven Acute Rejection [C-BPAR], long-term kidney function and death-censored graft loss over a median follow-up of five years. Episodes of C-BPAR were noted at a median of two years post-transplant. Adjusted odds of having a subsequent C-BPAR was significantly higher in the SCI-T group [SC-BLR and SC-TCMR] compared to NSI 3.8 (2.1-7.5). The adjusted hazard for death-censored graft loss was significantly higher with SCI-T compared to NSI [1.99 (1.04-3.84)]. Overall, SCI detected through surveillance biopsy within the first year post-transplant is a harbinger for subsequent immunological events and is associated with a significantly greater hazard for subsequent C-BPAR and death-censored graft loss. Thus, our study highlights the need for identifying patients with SCI through surveillance biopsy and develop strategies to prevent further alloimmune injuries.

Back Table Preparation of the Right Lobe Live Donor Liver Allograft: A Crucial Part of the Adult Live Donor Liver Transplant Procedure.

INTRODUCTION: We aimed to describe our procedure for vascular reconstruction and back table bench preparation for the right lobe live donor allograft. Live donor liver transplantation (LDLT) remains an important option for the expansion of the donor pool. The procedure has been widely used, and its success is dependent on a technically perfect operation with appropriate inflow and outflow of the allograft. Adequate preparation of the right lobe (RL) allograft prior to implantation remains a vital part of the procedure. METHODS: Our technique of back table vascular reconstruction of the RL allograft has been performed using a hepatic vein patch venoplasty, inferior hepatic vein inclusion, portal vein reconstruction, and segment V and VIII reconstruction for all of our LDLTs. RESULTS: Between March 2009 and January 2020, 321 consecutive adult LDLTs were performed and underwent back table reconstruction with the techniques described. During that time period, no patients had hepatic insufficiency. There was a single thrombosis of a superior mesenteric vein (SMV) to PV jump conduit. CONCLUSIONS: Our technique of back table reconstruction of the LDLT right lobe graft remains a crucial part of the operative procedure. Our experience with RL grafts without middle hepatic vein (MHV) and our systematic approach for inflow and outflow reconstruction has yielded excellent results with no technical outflow issues and minimal inflow complications.

The closing survival gap after liver transplantation for hepatocellular carcinoma in the United States.

BACKGROUND: Socio-economic inequalities among different racial/ethnic groups have increased in many high-income countries. It is unclear, however, whether increasing socio-economic inequalities are associated with increasing differences in survival in liver transplant (LT) recipients. METHODS: Adults undergoing first time LT for hepatocellular carcinoma (HCC) between 2002 and 2017 recorded in the Scientific Registry of Transplant Recipients (SRTR) were included and grouped into three cohorts. Patient survival and graft survival stratified by race/ethnicity were compared among the cohorts using unadjusted and adjusted analyses. RESULTS: White/Caucasians comprised the largest group (n=9,006, 64.9%), followed by Hispanic/Latinos (n=2,018, 14.5%), Black/African Americans (n=1,379, 9.9%), Asians (n=1,265, 9.1%) and other ethnic/racial groups (n=188, 1.3%). Compared to Cohort I (2002-2007), the 5-year survival of Cohort III (2012-2017) increased by 18% for Black/African Americans, by 13% for Whites/Caucasians, by 10% for Hispanic/Latinos, by 9% for patients of other racial/ethnic groups and by 8% for Asians (All P values<0.05). Despite Black/African Americans experienced the highest survival improvement, their overall outcomes remained significantly lower than other ethnic∕racial groups (adjusted HR for death=1.20; 95%CI 1.05-1.36; P=0.005; adjusted HR for graft loss=1.21; 95%CI 1.08-1.37; P=0.002). CONCLUSION: The survival gap between Black/African Americans and other ethnic/racial groups undergoing LT for HCC has significantly decreased over time. However, Black/African Americans continue to have the lowest survival among all racial/ethnic groups.

Function and longevity of renal grafts from high-KDPI donors.

BACKGROUND: High kidney-donor profile index (KDPI) kidneys have a shorter survival than grafts with lower KDPI values. It is still unclear, however, whether their shorter longevity depends on an inferior baseline function, faster functional decline, or the combination of both. METHODS: We analyzed the estimated glomerular filtration rate (eGFR) of 605 consecutive recipients of deceased donor kidney transplants (KT) at 1, 3, 6, 12, 18, 24, 36, 48, and 60 months. Comparisons were performed among four groups based on KDPI quartile: Group I-KDPI ≤ 25% (n = 151), Group II-KDPI 26-50% (n = 182), Group III-KDPI 51-75% (n = 176), and Group IV-KDPI 〉 75% (n = 96). Linear mixed model analysis was subsequently used to assess whether KDPI was independently associated with the decline in eGFR during the first 5-years after KT. We also analyzed the incidence of delayed graft function (DGF), rejection within the first year after KT, patient survival, graft survival, and death censored graft survival based on KDPI group. FINDINGS: High-KDPI grafts had lower eGFR immediately after KT, had a higher incidence of DGF and rejection. However, there were no signifcant differences in the adjusted rate (slope) of decline in eGFR among the four KDPI groups (P = .06). Although patient survival was signigicantly lower for recipients of high-KDPI grafts, death-censored graft survival was similar among the four KDPI groups (P = .33). CONCLUSIONS: The shorter functional survival of high-KDPI grafts seems to be due to their lower baseline eGFR rather than a more rapid functional decline after KT.

Treatment modalities and long-term outcomes of hepatic hemangioendothelioma in the United States.

BACKGROUND: We analyzed the outcomes of patients with hepatic epithelioid hemangioendothelioma (HEHE) in the United States after stratification by their most definitive treatment. METHODS: The National Cancer Data Base was used to identify patients with HEHE between 2004 and 2018. Patients were divided in four treatment groups: no surgical therapy, ablation, liver resection or liver transplantation. Demographics and clinical characteristics were compared, and Kaplan Meier functions and Cox-regression were used for unadjusted and adjusted survival analyses. RESULTS: Among a total of 334 patients, 218 (65.2%) were managed non-surgically, 74 (22.1%) underwent hepatic resections, 35 (10.4%) underwent liver transplantation and 7 (2.1%) underwent ablations. The overall median survival was 111 months (95%CI 73-149) after liver transplantation, 69 months (95%CI 45-92) after hepatic resection, 38 months (95%CI 0-78) after ablation and 80 months (95%CI 70-90) for patients managed by watchful waiting (P < 0.001). After adjustment, patients who underwent liver transplantation were found to have a better survival when compared to other therapies (Hazard Ratio: 0.61, 95% Confidence Interval: 0.38-0.97, p = 0.035). CONCLUSIONS: This study reports the outcomes of the largest cohort of patients with HEHE. The longest survival was observed after liver transplantation, followed by non-surgical management and hepatic resection. Because of selection bias, future studies to better characterize what criteria should be used for the selection of treatment modalities for HEHE are urgently needed.

The Clinical Impact of Anti-HLA Donor Specific Antibody Detection Through First Year Screening on Stable Kidney Transplant Recipients.

Anti-HLA Donor Specific Antibody (DSA) detection post kidney transplant has been associated with adverse outcomes, though the impact of early DSA screening on stable patients remain unclear. We analyzed impact of DSA detection through screening in 1st year stable patients (n = 736) on subsequent estimated glomerular filtration rate (eGFR), death censored graft survival (DCGS), and graft failure (graft loss including return to dialysis or re-transplant, patient death, or eGFR < 20 ml/min at last follow up). Patients were grouped using 1st year screening into DSA+ (Class I, II; n = 131) or DSA- (n = 605). DSA+ group were more DR mismatched (p = 0.02), more sensitized (cPRA ≥90%, p = 0.002), less Caucasian (p = 0.04), and had less pre-emptive (p = 0.04) and more deceased donor transplants (p = 0.03). DSA+ patients had similar eGFR (54.8 vs. 53.8 ml/min/1.73 m2, p = 0.56), DCGS (91% vs. 94%, p = 0.30), and graft failure free survival (76% vs. 82%, p = 0.11). DSA timing and type did not impact survival. Among those with a protocol biopsy (n = 515), DSA detected on 1st year screening was a predictor for graft failure on multivariate analysis (1.91, 95% CI 1.03-3.55, p = 0.04). Overall, early DSA detection in stable patients was an independent risk factor for graft failure, though only among those who underwent a protocol biopsy.

Increasing Living Donor Liver Transplantation Using Liver Paired Exchange.

BACKGROUND: Living donor liver transplantation (LDLT) continues to be the primary modality of liver transplantation in Asia, but it accounts for about 5% of all liver transplantations in the US. ABO incompatibility is the primary reason motivated donors are declined. Although kidney paired exchanges are common, liver paired exchange (LPE) is still evolving in the US. STUDY DESIGN: This is a retrospective review (between January 1, 2019, and July 31, 2021) of our initial experience with LPE. RESULTS: A total of 10 LPEs (20 LDLTs) were performed during the study period. Seven LPEs were initiated by a nondirected O donor. The other 3 pair sets involved 1 ABO compatible and 1 ABO incompatible pair. Transplantations in a pair set were completed within a mean of 4.8 (range 1-14) days of each other. All 20 donors are doing well with no major complications at 12.7 (range 1-20) months. Seventeen of 20 recipients are alive and have good allograft function. One recipient died in the early postoperative period. Two late deaths of patients with functioning allografts were due to COVID-19 (at 8 months) and peritoneal carcinomatosis and gram-negative sepsis (at 9 months). CONCLUSIONS: LPE is feasible in a high-volume LDLT center and is a useful option to increase LDLT by overcoming ABO incompatibility. Nondirected donors can be utilized to initiate an LPE.

Rabbit antithymocyte globulin dose and early subclinical and clinical rejections in kidney transplantation.

Antithymocyte globulin (ATG) is a commonly used induction agent in kidney transplant recipients. However, the optimal dosing has not been well defined. Our protocol aims for a 5-6 mg/kg cumulative dose. It is unclear if a dose lower than 5 mg/kg is associated with more rejection. We performed a retrospective cohort study of patients who received a kidney transplant at our center between January 1, 2013 and December 31, 2016. Primary outcome was biopsy proven acute rejection (clinical and subclinical) in the first 6 months after kidney transplant. CMV viremia in high risk (D+/R-) recipients and BK viremia was compared as a secondary endpoint. Of the 543 patients, the Low Dose (LD) group (n = 56) received <5 mg/kg ATG and Regular Dose (RD) group (n = 487) received ≧5 mg/kg. Patients in RD were more sensitized (higher PRA and CPRA). LD received a dose of 4 ± 1.1 mg/kg ATG whereas RD received 5.6 ± .3 mg/kg ATG (P < .001). TCMR (Banff 1A or greater) was present in 34% of patients in LD versus 22% in RD (P = .04) (OR 2.1; 95%CI 1.12-3.81; P = .019). There was no difference in the incidence of CMV or BK viremia. ATG doses lower than 5 mg/kg may be associated with a heightened risk of rejection despite a low degree of sensitization.

The Use of Machine Learning to Create a Risk Score to Predict Survival in Patients with Hepatocellular Carcinoma: A TCGA Cohort Analysis.

Introduction: Hepatocellular carcinoma (HCC) accounts for approximately 90% of primary liver malignancies and is currently the fourth most common cause of cancer-related death worldwide. Due to varying underlying etiologies, the prognosis of HCC differs greatly among patients. It is important to develop ways to help stratify patients upon initial diagnosis to provide optimal treatment modalities and follow-up plans. The current study uses Artificial Neural Network (ANN) and Classification Tree Analysis (CTA) to create a gene signature score that can help predict survival in patients with HCC. Methods: The Cancer Genome Atlas (TCGA-LIHC) was analyzed for differentially expressed genes. Clinicopathological data were obtained from cBioPortal. ANN analysis of the 75 most significant genes predicting disease-free survival (DFS) was performed. Next, CTA results were used for creation of the scoring system. Cox regression was performed to identify the prognostic value of the scoring system. Results: 363 patients diagnosed with HCC were analyzed in this study. ANN provided 15 genes with normalized importance >50%. CTA resulted in a set of three genes (NRM, STAG3, and SNHG20). Patients were then divided in to 4 groups based on the CTA tree cutoff values. The Kaplan-Meier analysis showed significantly reduced DFS in groups 1, 2, and 3 (median DFS: 29.7 months, 16.1 months, and 11.7 months, p < 0.01) compared to group 0 (median not reached). Similar results were observed when overall survival (OS) was analyzed. On multivariate Cox regression, higher scores were associated with significantly shorter DFS (1 point: HR 2.57 (1.38-4.80), 2 points: 3.91 (2.11-7.24), and 3 points: 5.09 (2.70-9.58), p < 0.01). Conclusion: Long-term outcomes of patients with HCC can be predicted using a simplified scoring system based on tumor mRNA gene expression levels. This tool could assist clinicians and researchers in identifying patients at increased risks for recurrence to tailor specific treatment and follow-up strategies for individual patients.
