RESUMO
BACKGROUND: Small bowel adenocarcinoma is a rare disease. The genomic profiling tumours according to clinical characteristics and its impact on the prognosis remains unclear. METHODS: A pooled analysis of clinical data, genomic profiling and MisMatch Repair (MMR) status from three databases was performed. RESULTS: A total of 188 tumour samples were analysed. A predisposing disease was reported in 22.3%, mainly Lynch syndrome and Crohn's disease. The tumours were localized in 80.2% and metastatic in 18.8%. The most frequent mutations were KRAS (42.0%) among them 7/79 are G12C, TP53 (40.4%), APC (19.1%), PIK3CA (18.6%), SMAD4 (12.8%) and ERBB2 (9.6%). Mutation distribution differed according to predisposing disease for TP53, ERBB2, IDH1, FGFR3, FGFR1 and KDR. KRAS and SMAD4 mutations were more frequent in metastatic tumour, whereas ERBB2 mutations were absent in metastatic tumour. For localized tumour, APC mutation was independently associated with a poor overall survival (OS) (p = 0.0254). 31.8% of localized tumours and 11.3% of metastatic tumours were dMMR (29.8% of the entire cohort). A dMMR status was associated with a better OS (HR = 0.61 [0.39-0.96], p = 0.0316). CONCLUSIONS: There is a different genomic profile according to the stage and predisposing disease. dMMR and APC mutation in localized tumour predict a better prognosis.

INTRODUCTION: Overweight is a negative prognostic factor in the general population in the long term. However, the role of body mass index (BMI) in the short-mid term in advanced tumours is unclear. The present analysis investigates the role of BMI weight classes in a large sample of patients affected by HCC and receiving atezolizumab plus bevacizumab or lenvatinib as first-line treatment. METHODS AND MATERIAL: The cohort included consecutive patients affected by BCLC-c and BCLC-B HCC patients from a multicenter international study group who received atezolizumab plus bevacizumab or lenvatinib as first-line therapy. Population was stratified according to the BMI in under-, over- and normal-weight according to the conventional thresholds. The primary objective of the study was to evaluate the prognostic and predictive impact of BMI in patients affected by advanced or intermediate HCC. Survival curves were estimated using the product-limit method of Kaplan-Meier. The role of stratification factors was analysed with log-rank tests. RESULTS: 1292 consecutive patients with HCC were analysed. 466 (36%) patients were treated with lenvatinib and 826 (64%) patients were treated with atezolizumab plus bevacizumab. In the atezolizumab plus bevacizumab arm, 510 (62%) patients were normal-weight, 52 (6%) underweight and 264 (32%) overweight. At the univariate analysis for OS, underweight patients had significantly shorter OS compared to normal-weight patients, whereas no differences were found between normal-weight versus overweight. Multivariate analysis confirmed that underweight patients had significantly shorter OS compared to normal-weight patients (HR: 1.7; 95% CI: 1.0-2.8; p = .0323). In the lenvatinib arm, 26 patients (5.6%) were categorized as underweight, 256 (54.9%) as normal-weight, and 184 (39.5%) as overweight. At the univariate analysis for OS, no significant differences were found between normal-weight versus underweight and between normal-weight versus overweight, which was confirmed at multivariate analysis. CONCLUSION: Our analysis highlighted a prognostic role of BMI in a cohort of patients with advanced HCC who received atezolizumab plus bevacizumab, while no prognostic role for low BMI was apparent in patients who received lenvatinib.

BACKGROUND: Clinical benefits of atezolizumab plus bevacizumab (atezolizumab-bevacizumab) are observed only in a subset of patients with hepatocellular carcinoma and the development of biomarkers is needed to improve therapeutic strategies. The atezolizumab-bevacizumab response signature (ABRS), assessed by molecular biology profiling techniques, has been shown to be associated with progression-free survival after treatment initiation. The primary objective of our study was to develop an artificial intelligence (AI) model able to estimate ABRS expression directly from histological slides, and to evaluate if model predictions were associated with progression-free survival. METHODS: In this multicentre retrospective study, we developed a model (ABRS-prediction; ABRS-P), which was derived from the previously published clustering-constrained attention multiple instance learning (or CLAM) pipeline. We trained the model fit for regression analysis using a multicentre dataset from The Cancer Genome Atlas (patients treated by surgical resection, n=336). The ABRS-P model was externally validated on two independent series of samples from patients with hepatocellular carcinoma (a surgical resection series, n=225; and a biopsy series, n=157). The predictive value of the model was further tested in a series of biopsy samples from a multicentre cohort of patients with hepatocellular carcinoma treated with atezolizumab-bevacizumab (n=122). All samples in the study were from adults (aged ≥18 years). The validation sets were sampled between Jan 1, 2008, to Jan 1, 2023. For the multicentre validation set, the primary objective was to assess the association of high versus low ABRS-P values, defined relative to cross-validation median split thresholds in the first biopsy series, with progression-free survival after treatment initiation. Finally, we performed spatial transcriptomics and matched prediction heatmaps with in situ expression profiles. FINDINGS: Of the 840 patients sampled, 641 (76%) were male and 199 (24%) were female. Across the development and validation datasets, hepatocellular carcinoma risk factors included alcohol intake, hepatitis B and C virus infections, and non-alcoholic steatohepatitis. Using cross-validation in the development series, the mean Pearson's correlation between ABRS-P values and ABRS score (mean expression of ABRS genes) was r=0·62 (SD 0·09; mean p<0·0001, SD<0·0001). The ABRS-P generalised well on the external validation series (surgical resection series, r=0·60 [95% CI 0·51-0·68], p<0·0001; biopsy series, r=0·53 [0·40-0·63], p<0·0001). In the 122 patients treated with atezolizumab-bevacizumab, those with ABRS-P-high tumours (n=74) showed significantly longer median progression-free survival than those with ABRS-P-low tumours (n=48) after treatment initiation (12 months [95% CI 7-not reached] vs 7 months [4-9]; p=0·014). Spatial transcriptomics showed significantly higher ABRS score, along with upregulation of various other immune effectors, in tumour areas with high ABRS-P values versus areas with low ABRS-P values. INTERPRETATION: Our study indicates that AI applied on hepatocellular carcinoma digital slides is able to serve as a biomarker for progression-free survival in patients treated with atezolizumab-bevacizumab. This approach could be used in the development of inexpensive and fast biomarkers for targeted therapies. The combination of AI heatmaps with spatial transcriptomics provides insight on the molecular features associated with predictions. This methodology could be applied to other cancers or diseases and improve understanding of the biological mechanisms that drive responses to treatments.

INTRODUCTION: The prognostic nutritional index (PNI) is a multiparametric score introduced by Onodera based on the blood levels of lymphocytes and albumin in patients with gastrointestinal neoplasms. Regarding hepatocellular carcinoma (HCC), its prognostic role has been shown in patients treated with sorafenib and lenvatinib. The aim of this real-world study was to investigate the association between clinical outcomes and PNI in patients being treated with atezolizumab plus bevacizumab. METHODS: The overall cohort of this multicentric study included 871 consecutive HCC patients from 5 countries treated with atezolizumab plus bevacizumab in first-line therapy. The PNI was calculated as follows: 10 × serum albumin concentration (g/dL) + 0.005 × peripheral lymphocyte count (number/mm3). RESULTS: Data regarding lymphocyte counts and albumin levels were available for 773 patients; therefore, these patients were included in the final analysis. The cut-off point of the PNI was determined to be 41 by receiver operating characteristic analysis. 268 patients (34.7%) were categorized as the PNI-low group, while the remaining 505 (65.3%) patients as the PNI-high group. At the univariate analysis, high PNI was associated with longer overall survival (OS) (22.5 vs. 10.1 months, HR 0.34, p <0.01) and progression-free survival (PFS) (8.7 vs. 5.8 months, HR 0.63, p <0.01) compared to patients with low PNI. At the multivariate analysis, high versus low PNI resulted as an independent prognostic factor for OS (HR 0.49, p <0.01) and PFS (HR 0.82, p = 0.01). There was no difference in objective response rate between the two groups (high 26.1% vs. low 19.8%, p = 0.09), while disease control rate was significantly higher in the PNI-high group (76.8% vs. 66.4%, p = 0.01). CONCLUSION: PNI is an independent prognostic factor for OS and PFS in HCC patients on first-line treatment with atezolizumab plus bevacizumab.

BACKGROUND: The TOPAZ-1 phase III trial reported a survival benefit with the anti-programmed death cell ligand 1 (anti-PD-L1) durvalumab in combination with gemcitabine and cisplatin in patients with advanced biliary tract cancer. The present study investigated the efficacy and safety of this new standard treatment in a real-world setting. METHODS: The analysed population included patients with unresectable, locally advanced or metastatic adenocarcinoma of the biliary tract treated with durvalumab in combination with gemcitabine and cisplatin at 17 Italian centres. The primary endpoint of the study was progression-free survival (PFS), whereas secondary endpoints included overall survival (OS), overall response rate (ORR) and safety. Unadjusted and adjusted hazard ratios (HRs) by baseline characteristics were calculated using the Cox proportional hazards model. RESULTS: From February 2022 to November 2022, 145 patients were enrolled. After a median follow-up of 8.5 months (95% CI: 7.9-13.6), the median PFS was 8.9 months (95% CI: 7.4-11.7). Median OS was 12.9 months (95% CI: 10.9-12.9). The investigator-assessed confirmed ORR was 34.5%, and the disease control rate was 87.6%. Any grade adverse events (AEs) occurred in 137 patients (94.5%). Grades 3-4 AEs occurred in 51 patients (35.2%). The rate of immune-mediated AEs (imAEs) was 22.7%. Grades 3-4 imAEs occurred in 2.1% of the patients. In univariate analysis, non-viral aetiology, ECOG PS >0 and NLR ≥3 correlated with shorter PFS. CONCLUSION: The results reported in this first real-world analysis mostly confirmed the results achieved in the TOPAZ-1 trial in terms of PFS, ORR and safety.

AIM: Lenvatinib is used to treat advanced hepatocellular carcinoma (HCC). Metabolic dysfunction-associated fatty liver disease (MAFLD) is becoming a major etiology of HCC. We aimed to evaluate the impact of MAFLD on the efficacy of lenvatinib. METHODS: We enrolled 320 patients with HCC who were treated with lenvatinib. All patients were classified into the MAFLD (n = 155) and non-MAFLD (n = 165) groups. Independent factors for overall survival (OS) were analyzed. In the stratification analysis, HCC was categorized as non-viral (n = 115) or viral HCC (n = 205). RESULTS: The OS rate was significantly higher in the MAFLD group than in the non-MAFLD group (median 21.1 vs. 15.1 months, p = 0.002). Multivariate analysis demonstrated that, in addition to albumin-bilirubin grade and Barcelona Clinic Liver Cancer stage, MAFLD was identified as an independent factor for OS (HR 0.722, 95% CI 0.539-0.966, p = 0.028). In the stratification analysis, the OS rate was significantly higher in the MAFLD group than in the non-MAFLD group among patients with non-viral HCC (median 21.1 vs. 15.1 months, p = 0.002), but not in patients with viral HCC. Furthermore, MAFLD was an independent negative risk factor for OS in patients with non-viral HCC (HR 0.506, 95% CI 0.297-0.864, P < 0.01). However, MAFLD was not an independent factor for OS in patients with viral HCC. CONCLUSIONS: MAFLD was a beneficial factor for survival in patients with HCC treated with lenvatinib. Moreover, the better OS of the MAFLD group was more pronounced in patients with non-viral HCC. Lenvatinib may be a suitable agent for patients with non-viral HCC and MAFLD.
RESUMO
Isocitrate dehydrogenase (IDH)1/2 mutations are the most frequent druggable alterations in intrahepatic cholangiocarcinoma (iCCA), reported in ~20% of cases. Preclinical evidence indicates that these mutations are associated with homologous recombination deficiency (HRD), which could be exploited as a target for platinum chemotherapy (ChT) and PARP inhibitors. However, the role of IDH1/2 mutations as surrogate biomarkers for platinum efficacy is unknown. We conducted a multicenter, propensity score-matched analysis to investigate the impact of IDH1/2 mutations on progression-free survival (PFS), overall response rate (ORR) and disease control rate (DCR) in patients with iCCA treated with platinum-based ChT. An exploratory comparison of complex HRD estimates between IDH1/2 mutated and wild-type tumors from TCGA was also performed. A total of 120 cases were matched in a 1:1 ratio (60 IDH1/2 mutant and 60 wild-type). No differences were observed for platinum-based PFS (7.7 vs 7.3 months, P = .970), DCR (66.1% vs 74.1%, P = .361) and ORR (27.8% vs 25.0%, P = .741). IDH1/2 mutations showed mutual exclusivity with genomic alterations in ATM, BRCA2, MST1R, NF1, FGFR2 and CDKN2A/B losses, respectively, with no clear survival and response differences. Among TCGA tumors, IDH1/2 mutated CCA did not show higher HRD compared to wild-type cases. IDH1/2 mutations are not associated with increased sensitivity to platinum-based ChT in iCCA patients. Deeper genomic sequencing is needed to elucidate the HRD phenotype in IDH1/2 mutant iCCA and exploit its therapeutic vulnerabilities.

AIM: The identification of new prognostic factors able to stratify hepatocellular carcinoma patients candidate to first-line therapy is urgent. In the present work we validated the prognostic value of the lenvatinib prognostic index. METHODS: Data of Eastern and Western patients treated with lenvatinib as first-line for Barcelona Clinic Liver Cancer stage B or C hepatocellular carcinoma were recollected. The lenvatinib prognostic index was composed by three classes of risk according with our previous study. The "low risk" group includes patients with prognostic nutritional index (PNI) >43.3 and with previous transarterial chemoembolization. The "medium risk" group includes patients with PNI >43.3, but without previous transarterial chemoembolization and patients with PNI <43.3, albumin-bilirubin grade 1 and Barcelona Clinic Liver Cancer stage B. The "high risk" group includes patients with PNI <43.3, albumin-bilirubin grade 2, and patients with PNI <43.3, albumin-bilirubin grade 1 and Barcelona Clinic Liver Cancer stage C. RESULTS: A total of 717 patients were included. The median overall survival was 20.7 months (95% CI 16.1-51.6) in patients with low risk (n = 223), 16.7 months (95% CI 13.3-47.0) in patients with medium risk (n = 264), and 10.7 months (95% CI 9.3-12.2) in patients with high risk (n = 230; HR 1, 1.29, and 1.92, respectively; p < 0.0001). Median progression-free survival was 7.3 months (95% CI 6.3-46.5) in patients with low risk, 6.4 months (95% CI 5.3-8.0) in patients with medium risk ,and 4.9 months (95% CI 4.3-5.5) in patients with high risk (HR 1, 1.07, 1.47 respectively; p = 0.0009). CONCLUSION: The lenvatinib prognostic index confirms its prognostic value on an external cohort of hepatocellular carcinoma patients treated with Lenvatinib.
RESUMO
Background: This multicenter study investigated the predictive value of baseline AFP and on-treatment AFP response for survival in hepatocellular carcinoma (HCC) patients with regorafenib. Materials & methods: A total of 578 patients with HCC treated with regorafenib from 12 institutions in South Korea and Italy were included. Baseline AFP (cutoff, 400 ng/ml) and AFP response (20% reduction from baseline) were analyzed for overall survival (OS) and progression-free survival (PFS). Results: Baseline AFP below 400 ng/ml was a significant factor that was independently associated with longer OS and PFS. AFP response was also a significant factor independently associated with longer OS and PFS. Conclusion: Baseline AFP and AFP response may be used as prognostic factors for survival in HCC treated with regorafenib.
Regorafenib is standard second-line therapy for patients with hepatocellular carcinoma (HCC) who show failure to sorafenib treatment, but there is no reliable factor to predict survival. In this multicenter, retrospective study with patients from South Korea and Italy, we have found that both baseline AFP level and on-treatment AFP response have independent predictive value for survival in patients with HCC under regorafenib treatment. We observed similar results when the patients were divided according to their nationality (South Korea vs Italy), despite the fact that the baseline characteristics of the patients from the two cohorts were significantly different.

BACKGROUND AND AIMS: In the last few years, there has been increasing interest in non-cancer medications and their potential anti-cancer activity. Data are not available in cholangiocarcinoma (CCA) patients. The aim of this study is to fill this gap by investigating the potential impact in terms of clinical outcome of the common non-cancer medications. METHODS: All consecutive patients with CCAs were retrospectively identified from 7 Italian medical institutions. We investigated the role of intake of vitamin D, aspirin, metformin, statins, and diuretics. RESULTS: A total of 537 patients with CCAs were identified; 197 patients undergoing surgery were evaluated for disease-free survival (DFS), and 509 patients with an advanced stage were evaluated for overall survival (OS). A longer DFS was found in patients with intake of vitamin D versus never users (HR 0.55, 95% CI 0.32-0.92, p = 0.02). In an advanced stage an association with OS was found in patients with intake of metformin versus never users (HR 0.70, 95% CI 0.52-0.93, p = 0.0162), and in patients who have started taking metformin after chemotherapy versus before chemotherapy and never users (HR 0.44, 95% CI 0.26-0.73, p = 0.0016). CONCLUSIONS: Our results highlighted that vitamin D intake improves DFS in patients undergoing surgery. Metformin intake after starting chemotherapy can improve the clinical outcome in advanced disease. These results could open up new therapeutic strategies in cholangiocarcinoma patients. We are planning to undertake a prospective study to validate these data.

PURPOSE: Data from common clinical practice were used to generate balanced cohorts of patients receiving either sorafenib or lenvatinib, for unresectable hepatocellular carcinoma, with the final aim to investigate their declared equivalence. METHODS: Clinical features of lenvatinib and sorafenib patients were balanced through inverse probability of treatment weighting (IPTW) methodology, which weights patients' characteristics and measured outcomes of each patient in both treatment arms. Overall survival was the primary endpoint and occurrence of adverse events was the secondary. RESULTS: The analysis included 385 patients who received lenvatinib, and 555 patients who received sorafenib. In the unadjusted cohort, lenvatinib did not show a survival advantage over sorafenib (HR: 0.85, 95% CI 0.70-1.02). After IPTW adjustment, lenvatinib still not returned a survival advantage over sorafenib (HR: 0.82, 95% CI: 0.62-1.07) even in presence of balanced baseline characteristics. Lenvatinib provided longer survival than sorafenib in patients previously submitted to TACE (HR: 0.69), with PS of 0 (HR: 0.73) or without extrahepatic disease (HR: 0.69). CONCLUSION: Present results confirmed randomized controlled trial in the real-life setting, but also suggests that in earlier stages some benefit can be expected.

BACKGROUND AND AIM: Lenvatinib is a standard of care option in first-line therapy of advanced hepatocellular carcinoma (HCC). In the present study, we aim to identify, in patients with HCC treated with lenvatinib, a possible association between occurrence and grading of adverse events (AEs) and outcome. METHODS: We performed a retrospective analysis of 606 Japanese and Italian patients treated with lenvatinib in first-line setting and investigated the possible correlation between the onset of AEs, toxicity grade (G) and outcome measures such as overall survival (OS) and progression-free survival (PFS). RESULTS: The appearance of arterial hypertension G ≥ 2 independently predicted prolonged OS [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.46-0.93, P = .0188], whereas decreased appetite G ≥ 2 independently predicted decreased OS (HR 1.70, 95% CI 1.25-2.32, P = .0007) by multivariate analysis. Appearance of hand-foot skin reaction independently predicted prolonged PFS (HR 0.72, 95% CI 0.56-0.93, P = .0149), whereas decreased appetite G ≥ 2 predicted decreased PFS (HR 1.36, 95% CI 1.04-1.77, P = .0277). CONCLUSIONS: Our main findings are that the occurrence of arterial hypertension G ≥ 2 is a predictor of longer survival, whereas decreased appetite G ≥ 2 predicts for a poor prognosis. A careful management of AEs under lenvatinib treatment for HCC is required, to improve patients' quality of life, minimize the need for treatment discontinuation and achieve optimal outcome.

BACKGROUND: Standard treatment of advanced biliary tract cancer (aBTC) is represented by first-line chemotherapy (CT1). However, some patients do not gain any benefit from CT1, contributing to the overall dismal prognosis of aBTC. The present study aimed to devise a prognostic model in aBTC patients receiving CT1. METHODS: A large panel of clinical, laboratory, and pathology variables, available before the start of CT1, were retrospectively assessed in a multi-centric cohort to determine their prognostic value on univariate and multivariate regression analysis. The variables that showed a significant correlation with overall survival (OS) were computed in a three-tier prognostic score. External validation of the prognostication performance was carried out. RESULTS: Clinical histories of 935 patients (median OS 10.3 months), with diagnosis dates ranging from 2001 to 2017, were retrieved from 14 institutions. According to multivariate analysis, Eastern Cooperative Oncology Group performance status, carbohydrate antigen 19.9, albumin levels, and neutrophil/lymphocyte ratio were strongly associated with OS (p <0.01). The prognostic score could generate a highly significant stratification (all between-group p values ≤0.001) into groups of favorable (comprising 51.5% of the sample), intermediate (39.2%), and poor prognosis (9.3%): median OS was 12.7 (CI95% 11.0-14.4), 7.1 (CI95% 5.8-8.4), and 3.2 months (CI95% 1.7-4.7), respectively. This OS gradient was replicated in the validation set (129 patients), with median OS of 12.7 (CI95% 11.0-14.3), 7.5 (CI95% 6.1-8.9), and 1.4 months (CI95% 0.1-2.7), respectively (all between-group p values ≤0.05). CONCLUSION: A prognostic score, derived from a limited set of easily-retrievable variables, efficiently stratified a large population of unselected aBTC patients undergoing CT1. This tool could be useful to clinicians, to ascertain the potential benefit from CT1 at the start of treatment.

AIM: A link has been established between malnutrition, immunological status, and hepatocellular carcinoma (HCC). The prognostic nutritional index (PNI) has been recognized as a prognostic indicator in early-stage HCC and in patients treated with first-line therapy. However, to date, the role of the PNI in HCC patients treated with regorafenib has not been reported. METHODS: We undertook a multicentric analysis on a cohort of 284 patients affected by advanced HCC treated with regorafenib. The PNI was calculated as follows: 10 × serum albumin concentration (g/dl) + 0.005 × peripheral lymphocyte count (number/mm3 ). Univariate and multivariate analyses were used to investigate the association between PNI and survival outcomes. RESULTS: A PNI cut-off value of 44.45 was calculated by a receiver operating characteristic analysis. The median overall survival was 12.8 and 7.8 months for patients with high (>44.45) and low (≤44.45) PNI, respectively (hazard ratio, 0.58; 95% confidence interval, 0.43-0.77; p = 0.0002). In the univariate and multivariate analyses, low PNI value and increased serum bilirubin level emerged as independent prognostic factors for overall survival. No differences were found between high and low PNI in terms of progression-free survival (p = 0.14). CONCLUSION: If validated, the PNI could represent an easy-to-use prognostic tool able to guide the clinical decision-making process in HCC patients treated with regorafenib.
RESUMO
BACKGROUND: Advanced Hepatocarcinoma (HCC) is an important health problem worldwide. Recently, the REFLECT trial demonstrated the non-inferiority of Lenvatinib compared to Sorafenib in I line setting, thus leading to the approval of new first-line standard of care, along with Sorafenib. AIMS AND METHODS: With aim to evaluate the optimal choice between Sorafenib and Lenvatinib as primary treatment in clinical practice, we performed a multicentric analysis with the propensity score matching on 184 HCC patients. RESULTS: The median overall survival (OS) were 15.2 and 10.5 months for Lenvatinib and Sorafenib arm, respectively. The median progression-free survival (PFS) was 7.0 and 4.5 months for Lenvatinib and Sorafenib arm, respectively. Patients treated with Lenvatinib showed a 36% reduction of death risk (p = 0.0156), a 29% reduction of progression risk (p = 0.0446), a higher response rate (p < 0.00001) and a higher disease control rate (p = 0.002). Sorafenib showed to be correlated with more hand-foot skin reaction and Lenvatinib with more hypertension and fatigue. We highlighted the prognostic role of Barcelona Clinic Liver Cancer (BCLC) stage, Eastern Cooperative Oncology Group Performance Status (ECOG-PS), bilirubin, alkaline phosphatase and eosinophils for Sorafenib. Conversely, albumin, aspartate aminotransferase (AST), alkaline phosphatase and Neutrophil-Lymphocyte Ratio (NLR) resulted prognostic in Lenvatinib arm. Finally, we highlighted the positive predictive role of albumin > Normal Value (NV), ECOG > 0, NLR < 3, absence of Hepatitis C Virus positivity, and presence of portal vein thrombosis in favor of Lenvatinib arm. Eosinophil < 50 and ECOG > 0 negatively predicted the response to Sorafenib. CONCLUSION: SLenvatinib showed to better perform in a real-word setting compared to Sorafenib. More researches are needed to validate the predictor factors of response to Lenvatinib rather than Sorafenib.
RESUMO
BACKGROUND AND AIM: The aim of our retrospective study is to evaluate the prognostic significance of aspirin in patients with advanced HCC treated with sorafenib. METHODS: 304 patients with HCC,consecutively treated with sorafenib from May 2007 to September 2018, were included in the clinical study. Of Them 93 patients token aspirin. Progression-free survival (PFS)and overall survival (OS)were estimated with the Kaplan-Meier method and compared with the log-rank test. RESULTS: The concomitant use of sorafenib and aspirin was associated with a median OS of 18.3 months compared to 8.8 months of patients who did not receive aspirin (HR 0.57; P < 0.0001). The concomitant use of sorafenib and aspirin was associated with a median PFS of 7.3 months compared to 3.0 months of patients who did not receive aspirin (HR 0.61; P = 0.0003). In the multivariate analysis, the use of aspirin maintained an independent prognostic value for OS(HR 0.61; P = 0.0013). In second line the concomitant use of regorafenib and aspirin was associated with a median OS of 16.9 months compared to 8.0 months of patients who did not receive aspirin (HR 0.30; P = 0.02). CONCLUSION: Globally, our data seem to suggest that aspirin use may improve the clinical outcome of patients with advanced hepatocellular carcinoma receiving sorafenib and regorafenib.

INTRODUCTION: Advanced hepatocellular carcinoma (HCC) represents a significant global health burden, whose treatment has been recently revolutionized by the advent of biologic treatments. Despite that, innovative therapeutic regimens and approaches, especially immune-based, remain to be explored aiming at extending the therapeutic benefits to a wider population of patients. AREAS COVERED: This review comprehensively discusses the evolving landscape of biological treatment modalities for advanced HCC, including immune checkpoint inhibitors, antiangiogenic monoclonal antibodies, tumor-targeting monoclonal antibodies either naked or drug-conjugated, therapeutic vaccines, oncolytic viruses, adoptive cell therapies, and cytokine-based therapies. Key clinical trials and preclinical studies are examined, highlighting the actual or potential impact of these interventions in reshaping treatment paradigms for HCC. EXPERT OPINION: Tailored and rational combination strategies, leveraging the synergistic effects of different modalities, represent a promising approach to maximize treatment efficacy in advanced HCC, which should aim at conversion endpoints to increase the fraction of patients eligible for curative approaches. The identification of predictive biomarkers holds the key to optimizing patient selection and improving therapeutic outcomes.

INTRODUCTION: Incidental Gallbladder Cancer (IGBC) following cholecystectomy constitutes a significant portion of gallbladder cancer diagnoses. Re-exploration is advocated to optimize disease clearance and enhance survival rates. The consistent association of residual disease (RD) with inferior oncologic outcomes prompts a critical examination of re-resection's role as a modifying factor in the natural history of IGBC. METHODS: All patients diagnosed with gallbladder cancer between 2012 and 2022 were included. An elastic net regularized regression model was employed to profile high-risk predictors of RD within the IGBC group. Survival outcomes were assessed based on resection margins and RD. RESULTS: Among the 181 patients undergoing re-exploration for IGBC, 133 (73.5 %) harbored RD, while 48 (26.5 %) showed no evidence. The elastic net model, utilizing a selected λ = 0.029, identified six coefficients associated with the risk of RD: aspiration from cholecystectomy (0.141), hepatic tumor origin (1.852), time to re-exploration >8 weeks (1.879), positive margin status (2.575), higher T stage (1.473), and poorly differentiated tumors (2.241). Furthermore, the study revealed a median overall survival of 44 months (CI 38-60) for IGBC patients with no evidence of RD, compared to 31 months (23-42) for those with RD (p < 0.001). CONCLUSION: Re-resection revealed a high incidence of RD (73.5 %), significantly correlating with poorer survival outcomes. The preoperative identification of high-risk features provides a reliable biological disease profile. This aids in strategic preselection of patients who may benefit from re-resection, underscoring the need to consolidate outcomes with tailored chemotherapy for those with unfavorable characteristics.

INTRODUCTION: Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the first for primary liver tumors. In recent years greater therapeutic advancement was represented by employment of tyrosine kinase inhibitors (TKIs) either in monotherapy or in combination with immune checkpoint inhibitors (ICIs). AREAS COVERED: Major attention was given to target therapies in the last couple of years, especially in those currently under phase II trials. Priority was given either to combinations of novel ICI and TKIs or those targeting alternative mutations of major carcinogenic pathways. EXPERT OPINION: As TKIs are playing a more crucial role in HCC therapeutic strategies, it is fundamental to further expand molecular testing and monitoring of acquired resistances. Despite the recent advancement in both laboratory and clinical studies, further research is necessary to face the discrepancy in clinical practice.

BACKGROUND: The results reported in the TOPAZ-1 phase III trial led to the approval of the combination of cisplatin and gemcitabine with durvalumab as the new first-line standard of care for patients with locally advanced or metastatic cholangiocarcinoma. OBJECTIVE: We performed a clustering analysis to classify patients into different groups based on their mutation profile, correlating the results of the analysis with clinical outcomes. METHODS: We selected 51 patients with cholangiocarcinoma who were treated with the combination of chemotherapy and durvalumab and who were screened using the next-generation sequencing-based FoundationOne gene panel. We conducted mutation-based clustering of tumors and a survival analysis. RESULTS: Three main clusters were identified. Cluster 1 is mostly characterized by mutations in genes belonging to the chromatin modification pathway, altered in 100% of patients. Cluster 2 is characterized by the alteration of several pathways, among which DNA damage control, chromatin modification, RTK/RAS, cell-cycle apoptosis, TP53, and PI3K were the most affected. Finally, most altered pathways in cluster 3 were RTK/RAS and cell-cycle apoptosis. Overall response rate was 4/13 (31%), 12/24 (50%), and 0/10 (0%) in cluster 1, cluster 2, and cluster 3, respectively, and the difference between the three clusters was statistically significant (p = 0.0188). CONCLUSIONS: By grouping patients into three clusters with distinct molecular and genomic alterations, our analysis showed that patients included in cluster 2 had higher overall response rates, whereas patients included in cluster 3 had no objective response. Further investigations on larger and external cohorts are needed in order to validate our results.
