RESUMEN
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.

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.

INTRODUCTION: The prognosis of patients with advanced biliary tract cancer (BTC) is still poor, and new strategies improving patients' outcome are needed. In our trial we investigated safety and activity of nab-paclitaxel in combination with gemcitabine and oxaliplatin as first-line systemic treatment for patients with advanced BTC. METHODS: In this investigator-initiated, multicenter, dose-escalation, single-arm phase I/II trial, patients were accrued into cohorts of 3 patients and dose escalation was performed following the standard 3 + 3 rule. Primary endpoint was the proportion of patients free from progression at 6 months. Secondary endpoints included safety and tolerability of the combination; progression-free survival (PFS); overall survival (OS); objective response rate (ORR); duration of response. RESULTS: Between July 2017 and December 2020, 67 patients were treated. Among the 10 patients in the phase I, no dose-limiting toxicity was observed, and dose level 2 was defined as recommended phase II dose for the phase II part. At data cutoff, the 6-month PFS rate was 49.1 % (95 % CI 40.8-57.5 %) with 28 patients out of 57 free from progression or death at 6 months. Median PFS was 6.3 months (95 % CI 3.6-10.1) and median OS was 12.4 months (95 % CI 8-23). ORR was 20.89 %. Most common grade 3 and grade 1-2 drug-related adverse events were neutropenia and peripheral neuropathy, respectively. CONCLUSION: Triple chemotherapy demonstrated a favorable safety profile. However, the study did not meet its primary endpoint. Future studies will clarify the benefit of chemotherapy combinations in different settings. This trial is registered with ClinicalTrials.gov, NCT03943043.

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.

Introduction: Lenvatinib is indicated for the forefront treatment of advanced hepatocellular carcinoma (aHCC), but its use may be limited by the risk of esophagogastric varices (EGV) bleeding. This study assessed the prevalence, predictors, and complications of EGV in aHCC patients treated with lenvatinib. Methods: In this multicenter international retrospective study, cirrhotic patients treated with lenvatinib for aHCC, were enrolled if upper-gastrointestinal endoscopy was available within 6 months before treatment. Primary endpoint was the incidence of EGV bleeding during lenvatinib therapy; secondary endpoints were predictors for EGV bleeding, prevalence, and risk factors for the presence of EGV and high-risk EGV at baseline, as well as impact of EGV bleeding on patients' survival. Results: 535 patients were enrolled in the study (median age: 72 years, 78% male, 63% viral etiology, 89% Child-Pugh A, 16% neoplastic portal vein thrombosis [nPVT], 56% Barcelona Clinic Liver Cancer-C): 234 had EGV (44%), 70 (30%) were at high risk and 59 were on primary prophylaxis. During lenvatinib treatment, 17 patients bled from EGV (3 grade 5), the 12-month cumulative incidence being 3%. The only baseline independent predictor of EGV bleeding was the presence of baseline high-risk EGV (hazard ratio: 6.94, 95% confidence interval [CI]: 2.23-21.57, p = 0.001). In these patients the 12-month risk was 17%. High-risk varices were independently associated with Child-Pugh B score (odds ratio [OR]: 2.12; 95% CI: 1.08-4.17, p = 0.03), nPVT (OR: 2.54; 95% CI: 1.40-4.61, p = 0.002), and platelets <150,000/µL (OR: 2.47; 95% CI: 1.35-4.50, p = 0.003). Conclusion: In hepatocellular carcinoma patients treated with lenvatinib, the risk of EGV bleeding was mostly low but significant only in patients with high-risk EGV at baseline.
RESUMEN
BACKGROUND: The TOPAZ-1 phase III trial reported a survival benefit with the anti-programmed cell death ligand 1 (anti-PD-L1) durvalumab in combination with gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). OBJECTIVE: The present study investigated for the first time the impact on survival of adding durvalumab to cisplatin/gemcitabine compared with cisplatin/gemcitabine in a real-world setting. PATIENTS AND METHODS: The analyzed population included patients with unresectable, locally advanced, or metastatic BTC treated with durvalumab in combination with cisplatin/gemcitabine or with cisplatin/gemcitabine alone. The impact of adding durvalumab to chemotherapy in terms of overall survival (OS) and progression free survival (PFS) was investigated with univariate and multivariate analysis. RESULTS: Overall, 563 patients were included in the analysis: 213 received cisplatin/gemcitabine alone, 350 received cisplatin/gemcitabine plus durvalumab. At the univariate analysis, the addition of durvalumab was found to have an impact on survival, with a median OS of 14.8 months versus 11.2 months [hazard ratio (HR) 0.63, 95% confidence interval (CI) 0.50-0.80, p = 0.0002] in patients who received cisplatin/gemcitabine plus durvalumab compared to those who received cisplatin/gemcitabine alone. At the univariate analysis for PFS, the addition of durvalumab to cisplatin/gemcitabine demonstrated a survival impact, with a median PFS of 8.3 months and 6.0 months (HR 0.57, 95% CI 0.47-0.70, p < 0.0001) in patients who received cisplatin/gemcitabine plus durvalumab and cisplatin/gemcitabine alone, respectively. The multivariate analysis confirmed that adding durvalumab to cisplatin/gemcitabine is an independent prognostic factor for OS and PFS, with patients > 70 years old and those affected by locally advanced disease experiencing the highest survival benefit. Finally, an exploratory analysis of prognostic factors was performed in the cohort of patients who received durvalumab: neutrophil-lymphocyte ratio (NLR) and disease stage were to be independent prognostic factors in terms of OS. The interaction test highlighted NLR ≤ 3, Eastern Cooperative Oncology Group Performance Status (ECOG PS) = 0, and locally advanced disease as positive predictive factors for OS on cisplatin/gemcitabine plus durvalumab. CONCLUSION: In line with the results of the TOPAZ-1 trial, adding durvalumab to cisplatin/gemcitabine has been confirmed to confer a survival benefit in terms of OS and PFS in a real-world setting of patients with advanced BTC.

BACKGROUND: The TOPAZ-1 phase III trial showed a survival benefit with durvalumab plus gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). To understand this combination's real-world efficacy and tolerability, we conducted a global multicenter retrospective analysis of its first-line treatment outcomes. METHODS: We included patients with unresectable, locally advanced, or metastatic BTC treated with durvalumab, gemcitabine, and cisplatin at 39 sites in 11 countries (Europe, the United States, and Asia). The primary endpoint was overall survival (OS). RESULTS: 666 patients were enrolled. Median OS was 15.1 months and median PFS was 8.2 months. The investigator-assessed overall response rate was 32.7 %, with stable disease in 45.2 % of patients. High baseline CEA levels, ECOG PS > 0, metastatic disease, and NLR > 3 were associated with poor survival. Any grade adverse events (AEs) occurred in 92.9 % of patients (grade >2: 46.6 %). Immune-related AEs (irAEs) occurred in 20.0 % (grade >2: 2.5 %). Three deaths (0.5 %) were deemed treatment-related, none linked to immunotherapy. Common irAEs were rash (8.2 % all grades; 0.3 % grade >2), itching (10.3 % all grades; 0.2 % grade >2), and hypothyroidism (5.1 % all grades; 0.3 % grade >2). Durvalumab discontinuation rate due to AEs was 1.5 %. ESMO-recommended genes were analyzed and no outcome differences were found. A comparative analysis with a historical cohort of patients treated with chemotherapy alone confirmed the positive survival impact of durvalumab in combination with cisplatin/gemcitabine. CONCLUSION: This first global real-world analysis largely confirmed the TOPAZ-1 findings, supporting gemcitabine, cisplatin, and durvalumab as a first-line standard of care for patients with advanced BTC.

Background: The results of the phase III ClarIDHy trial led to the FDA approval of ivosidenib as a therapeutic option for patients with locally advanced or metastatic cholangiocarcinoma (CCA) harboring isocitrate dehydrogenase 1 (IDH1) mutations. We recently published the first data on the use of ivosidenib in a real-world setting. Objective: Here we report the updated survival results of 11 patients with locally advanced or metastatic IDH1-mutated CCA who received ivosidenib in clinical practice. Patients and methods: Patients treated with ivosidenib as second- and third-line treatments for advanced CCA have been collected with the aim to evaluate the survival outcomes. A molecular study has been performed by next generation sequencing essay. Results: Overall, 11 patients were included. After a median follow-up of 13.7 months, median progression-free survival from the start of treatment with ivosidenib was 4.4 months (95% CI: 2.0-5.8), whereas median overall survival was 15 months (95% CI: 6.6-15.0) regardless of treatment line. Disease control rate was 63%, with two patients achieving a partial response (18%). Eighteen percent of patients experienced at least one treatment-related adverse events (AEs), but no grade ⩾3 was reported. The most frequently observed grade 2 AEs were prolonged QT interval and hypomagnesemia. A molecular profiling was performed on 8 out of 11 patients, highlighting TP53, BAP1, CDKN2A, and CDKN2B as the most common co-altered genes in these patients. Conclusion: The present update confirms the results of our previous real-world experience on the use of ivosidenib in IDH1-mutated CCA. Real-world evidence on larger numbers of patients is needed to confirm our findings.
RESUMEN
PURPOSE: BRAF mutations are rare in biliary tract cancers (BTC), but are of interest given the recent developments in targeted therapy for BTC. We investigated the clinical outcomes in a cohort of BRAF-mutant advanced BTC treated with first-line chemotherapy. Furthermore, we investigated the genomic landscape of BRAF class I, II, and III mutations in the intrahepatic cholangiocarcinoma (iCCA) subgroup of BTC. EXPERIMENTAL DESIGN: We analyzed two nonoverlapping cohorts. We examined the genomic landscape of BRAF-mutated iCCA in a "genomic cohort" [187 class I, 82 class II, 113 class III BRAF mutants and 8,026 wildtype (WT)]. We also analyzed median progression-free survival (PFS) and overall survival (OS) on first-line chemotherapy in a separate multi-institutional "clinical cohort" of patients with BTC (including iCCA and extrahepatic cholangiocarcinoma (eCCA) and gallbladder cancer; 41 class I, 32 class II+III BRAF mutants and 1,042 WT). RESULTS: In the entire BTC clinical cohort, the median PFS was shorter for class I [HR, 2.11 (P < 0.001)] and class II+III [HR, 1.72 (P = 0.007)] as compared with BRAF WT. OS was also shorter in class I [HR, 2.04 (P = 0.011)] and class II+III [HR, 1.86 (P = 0.002)] as compared with BRAF WT. In the iCCA subgroup, class I alterations were mutually exclusive with FGFR2, IDH1/2, ERBB2, and KRAS mutations. Class II+III mutations appear to be mutually exclusive with FGFR2 and KRAS. CONCLUSIONS: In BTC, all classes of BRAF mutations are associated with a worse prognosis. BRAF mutations occur in 5% of iCCA subgroup and may be mutually exclusive with other targetable mutations.

INTRODUCTION: Cholangiocarcinomas (CCA) are rare, highly invasive tumors often diagnosed at an advanced disease stage with an associated poor prognosis. Surgery represents the only chance for curative-intent treatment, but recurrence rates remain high. Neoadjuvant or adjuvant chemotherapy are options for patients with resectable CCA to increase recurrence-free survival and overall survival, while palliative chemotherapy represents the treatment for unresectable disease. Global efforts are currently focused on the development of novel more effective therapies. AREAS COVERED: A review was conducted in August 2021 using the PubMed database with the following keywords: 'cholangiocarcinoma,' 'chemotherapy,' and 'therapy.' Manuscripts reporting on first- and second-line chemotherapy, neoadjuvant and adjuvant treatment regimens, and targeted therapies currently being tested or employed in the management of CCA were examined. EXPERT OPINION: The prognosis of CCA is negatively affected by several factors including a lack of reliable biomarkers leading to delayed diagnoses, high inter- and intra-tumoral heterogeneity, and few effective chemotherapy regimens. In pursuit of more effective therapies, ongoing trials are testing both conventional and targeted drugs.

Second-line treatments are standard care for advanced hepatocellular carcinoma (HCC) patients with preserved liver function who are intolerant of or progress on first-line therapy. However, determinants of treatment benefit and post-treatment survival (PTS) remain unknown. HCC patients previously treated with sorafenib and enrolled in second-line clinical trials were pooled according to the investigational treatment received and the subsequent regulatory approval: approved targeted agents and immune checkpoint inhibitors (AT) or other agents (OT) not subsequently approved. Univariate and multivariate analyses using Cox proportional hazards models established relationships among treatments received, clinical variables, and overall survival (OS) or PTS. For 174 patients (80 AT; 94 OT) analyzed, baseline factors for longer OS in multivariate analysis were second-line AT, absence of both portal vein thrombosis and extrahepatic spread (EHS). Treatment with AT (versus OT) was associated with significantly longer OS among patients with EHS (pinteraction = 0.005) and patients with low neutrophil-to-lymphocyte ratio (NLR; pinteraction = 0.032). Median PTS was 4.0 months (95% CI 2.8−5.3). At second-line treatment discontinuation, alpha-fetoprotein (AFP) levels <400 ng/dl, albumin-bilirubin (ALBI) grade 1, and enrolment onto subsequent trials independently predicted longer PTS. Treatment with AT, PVT, and EHS were prognostic factors for OS, while AFP, ALBI grade and enrolment onto a third-line trial were prognostic for PTS. Presence of EHS and low NLR were predictors of greater OS benefit from AT.
RESUMEN
Benefits of early palliative care referral in oncology are well-validated. At the Veneto Institute of Oncology-IRCCS, a simultaneous-care outpatient clinic (SCOC) has been active since 2014, where patients with advanced cancer are evaluated by an oncologist together with a palliative care team. We prospectively assessed SCOC patients' characteristics and SCOC outcomes through internal procedure indicators. Data were retrieved from the SCOC prospectively maintained database. There were 753 eligible patients. The median age was 68 years; primary tumor sites were gastrointestinal (75.2%), genitourinary (15.0%) and other sites (9.8%). Predominant symptoms were psychological issues (69.4%), appetite loss (67.5%) and pain (65.9%). Dyspnea was reported in 53 patients (7%) in the referral form, while it was detected in 226 patients (34.2%) during SCOC visits (p < 0.0001). Median survival of patients after the SCOC visit was 7.3 months. Survival estimates by the referring oncologist were significantly different from the actual survival. Psychological intervention was deemed necessary and undertaken in 34.6% of patients, and nutritional support was undertaken in 37.9% of patients. Activation of palliative care services was prompted for 77.7% of patients. Out of 357 patients whose place of death is known, 69.2% died at home, in hospice or residential care. With regard to indicators' assessment, the threshold was reached for 9 out of 11 parameters (81.8%) requested by the procedure. This study confirmed the importance of close collaboration between oncologists and palliative care teams in responding properly to cancer patients' needs. The introduction of a procedure with indicators allowed punctual assessment of a team's performance.
RESUMEN
BACKGROUND: The results of the pivotal RESORCE trial led to the approval of the tyrosine kinase inhibitor regorafenib as second-line treatment in advanced hepatocellular carcinoma (HCC) after sorafenib failure. Data about prognostic factors in a second-line HCC setting are scarce. OBJECTIVE: The aim of the present study was to investigate prognostic factors in a cohort of patients with advanced HCC treated with regorafenib after progressing on sorafenib. METHODS: We retrieved the data of 259 patients affected by advanced HCC treated with regorafenib as second-line treatment from four different Italian institutions and one South Korean institution and performed a recursive partitioning analysis to build a score system. RESULTS: At the first-step univariate analysis for overall survival (OS), alkaline phosphatase (ALP) was the most significant parameter and was chosen as the first node in our tree model. In the subpopulation of patients presenting with ALP ≤122 U/L (n=155) at baseline, the most statistically significant split was by progression-free survival (PFS) on previous sorafenib treatment, between patients with a PFS ≥ 6 months (n = 59) and patients with a PFS < 6 months (n = 96). In the subpopulation of patients with ALP ≤ 122 U/L and PFS to sorafenib ≥ 6 months, the final split was determined between patients with hepatitis B virus (HBV)-related liver disease (n = 22) and patients with no HBV-related liver disease (n = 37). In the subpopulation of patients presenting ALP >122 U/L (n = 104) at baseline, the most statistically significant split was by aspartate aminotransferase (AST) value, between patients with AST ≤ 56 U/L (n = 48) and patients with AST > 56 U/L (n = 56). We built the Regorafenib Prognostic Index (REP index) stratifying the population into "low-risk," "medium-risk," and "high-risk" groups. The difference in median OS between the three risk groups was statistically significant, being 20.8 months (95% confidence interval [CI] 10.0-46.3) in the "low-risk" group, 8.4 months (95% CI 7.2-1435.8) in the "medium-risk" group, and 5.5 months (95% CI 3.5-13.2) in the "high risk" group. The median PFS was 7.7 months (95% CI 3.7-19.3), 2.5 months (95% CI 2.1-28.8), and 2.4 months (95% CI 1.6-9.1) for the "low-risk," "medium-risk," and "high-risk" groups, respectively. CONCLUSION: The REP index is an independent prognostic factor for OS and PFS in patients with advanced HCC treated with regorafenib.

BACKGROUND: Recently, three published phase III trials highlighted the superiority of investigational drugs compared to placebo, thus leading to their approval in the second-line setting. We report here a MAIC of second-line MKI options for patients with HCC previously treated with sorafenib using individual real-world data of regorafenib and aggregate data of second-line cabozantinib from the CELESTIAL trial. METHODS: Data from 278 patients who received regorafenib as second-line therapy after sorafenib failure for unresectable HCC were used as IPD. Data inclusion were adapted to those reported in the CELESTIAL trial in the subset of patients who received sorafenib as the only prior therapy. Survival medians and rates were obtained from Kaplan-Meier curves, and differences between regorafenib and cabozantinib groups were explored through Cox regression adjusted for weights originating from MAIC. RESULTS: The median OS of the weighted regorafenib group was 11.1 months (IQR: 5.6-16.4) and 11.3 (IQR: 6.7-22.4) for cabozantinib; HR 0.83 (95%CI 0.62-1.09). The median PFS of the weighted regorafenib group was 3.0 months (IQR: 1.9-4.8) and 5.5 (IQR: 2.3-9.3) for cabozantinib; HR 0.50 (95%CI 0.41-0.62). In the subgroup who received prior sorafenib for < 3 months, the median OS of the regorafenib group was 6.5 months (IQR: 4.7-10.9) and 9.5 months (IQR: 5.9-18.2) for cabozantinib; HR 0.68 (95%CI 0.39-1.16). In the subgroup receiving prior sorafenib for 3 to < 6 months, the median OS of the regorafenib group was 8.0 months (IQR: 4.2-15.2) and 11.5 (IQR: 6.5-23.9) for cabozantinib; HR 0.66 (95%CI 0.42-1.02). In the subgroup receiving prior sorafenib for ≥ 6 months, the median OS of the regorafenib group was 13.4 (IQR: 8.1-46.5) and 12.3 (IQR: 6.6-22.9) for cabozantinib; HR 0.89 (95%CI 0.52-1.51). CONCLUSION: Our results confirmed no differences between regorafenib and cabozantinib in terms of OS. However, in earlier progressors on prior sorafenib a larger benefit might be expected from cabozantinib treatment.

PURPOSE: More than 50% of patients with stage IV colorectal cancer (metastatic colorectal cancer [mCRC]) relapse postresection. The efficacy of postoperative systemic treatment is limited in this setting. Thus, these patients would greatly benefit from the use of a reliable prognostic biomarker, such as circulating tumor DNA (ctDNA) to identify minimal or molecular residual disease (MRD). PATIENTS AND METHODS: We analyzed a cohort of 112 patients with mCRC who had undergone metastatic resection with curative intent as part of the PREDATOR clinical trial. The study evaluated the prognostic value of ctDNA, correlating MRD status postsurgery with clinical outcomes by using a personalized and tumor-informed ctDNA assay (bespoke multiple PCR, next-generation sequencing assay). Postresection, systemic therapy was given to 39.2% of the patients at the discretion of the treating physician. RESULTS: Postsurgical, MRD positivity was observed in 54.4% (61 of 112) of patients, of which 96.7% (59 of 61) progressed at the time of data cutoff (hazard ratio [HR]: 5.8; 95% CI, 3.5 to 9.7; P < .001). MRD-positive status was also associated with an inferior overall survival: HR: 16.0; 95% CI, 3.9 to 68.0; P < .001. At the time of analyses, 96% (49 of 51) of patients were alive in the MRD-negative arm compared with 52.4% (32 of 61) in the MRD-positive arm. Patients who did not receive systemic therapy and were MRD-negative in the combined ctDNA analysis at two time points had an overall survival of 100%. In the multivariate analysis, ctDNA-based MRD status was the most significant prognostic factor associated with disease-free survival (HR: 5.78; 95% CI, 3.34 to 10.0; P < .001). CONCLUSION: This study confirms that in mCRC undergoing resection of metastases, postoperative MRD analysis is a strong prognostic biomarker. It holds promises for being implemented in clinical decision making, informing clinical trial design, and further translational research.

INTRODUCTION: Cabozantinib has been approved by the European Medicine Agency (EMA) for hepatocellular carcinoma (HCC) previously treated with sorafenib. Cabozantinib is also being tested in combination with immune checkpoint inhibitors in the frontline setting. Real-life clinical data of cabozantinib for HCC are still lacking. Moreover, the prognostic factors for HCC treated with cabozantinib have not been investigated. METHODS: We evaluated clinical data and outcome of HCC patients who received cabozantinib in the legal context of named patient use in Italy. RESULTS: Ninety-six patients from 15 centres received cabozantinib. All patients had preserved liver function (Child-Pugh A), mostly with an advanced HCC (77.1%) in a third-line setting (75.0%). The prevalence of performance status (PS) > 0, macrovascular invasion (MVI), extrahepatic spread, and alpha-fetoprotein (AFP) >400 ng/mL was 50.0, 30.2, 67.7, and 44.8%, respectively. Median overall survival (OS) and progression-free survival were 12.1 (95% confidence interval 9.4-14.8) and 5.1 (3.3-6.9) months, respectively. Most common treatment-related adverse events (AEs) were fatigue (67.7%), diarrhoea (54.2%), anorexia (45.8%), HFSR (43.8%), weight loss (24.0%), and hypertension (24.0%). Most common treatment-related Grade 3-4 AEs were fatigue (6.3%), HFSR (6.3%), and increased aminotransferases (6.3%). MVI, ECOG-PS > 0, and AFP >400 ng/mL predicted a worse OS. Discontinuation for intolerance and no new extrahepatic lesions at the progression were associated with better outcomes. CONCLUSIONS: In a real-life Western scenario (mostly in a third-line setting), cabozantinib efficacy and safety data were comparable with those reported in its registration trial. Data regarding the prognostic factors might help in patient selection and design of clinical trials.
RESUMEN
BACKGROUND: Regorafenib has been shown to improve clinical outcomes compared to placebo, becoming a standard second-line therapy for sorafenib-progressed and -tolerated hepatocellular carcinoma (HCC) patients. OBJECTIVE: We performed a multicentre, retrospective study in Italy and Korea to evaluate the effectiveness of the treatment sequence sorafenib-regorafenib compared with sorafenib and physician's choice in a real-life setting. PATIENTS AND METHODS: A propensity score model was developed to control the results for baseline variable imbalances between the arm treated with sorafenib and regorafenib (S-R) and the arm treated with sorafenib and physician's choice (S-P). Survival analysis was conducted on the matched population. RESULTS: After the application of propensity score matching, we analysed 99 patients in the arm treated with S-R and 99 patients in the arm treated with S-P. For the S-R group, the median overall survival was 22.2 months (95% CI 17.1-27.4), compared to 17.9 months (95% CI 15.1-50.0) for the S-P group. The results of the univariate analysis showed a 31% reduction of death risk for patients treated with S-R (p = 0.0382) compared to patients treated with S-P. Interaction tests highlighted the predictive role of alpha-fetoprotein (AFP), neutrophil-to-lymphocyte ratio (NLR), and extrahepatic spread. CONCLUSION: This study provides additional proof of the superiority of the S-R treatment over the S-P treatment approach in advanced HCC patients from a real-life setting.

Sorafenib is the first multikinase inhibitor demonstrating a survival benefit for patients suffering from advanced hepatocellular carcinoma (HCC). However, 1 issue remains open: what is the factor able to predict which patients will be long survivors?In the present study, we harnessed the potential of conditional survival, aiming at estimating the probability that a patient receiving sorafenib survives for more than 3 years.The present multicentric study was conducted on a cohort of 438 HCC patients. The primary end point was conditional overall survival. Kaplan-Meier survival analysis was used to calculate conditional overall survival probabilities at 3 years.The 3-year conditional survival of patients without disease progression highlights that NLR and ECOG are the factors that most accurately predict the probability of long survival. The 3-year conditional survival of patients with disease progression showed a medium effect size for HCV status, alpha-fetoprotein and NLR at all time-points. Macro-vascular portal vein invasion, extra hepatic disease, and BCLC we have a large effect size at 6 months and a medium effect size at 12 and 24 months.Our findings support the use of baseline NLR for the identification of patients with a higher probability of long-survival. NLR should be used as a stratification factor in the forthcoming clinical trials on the drugs for the advanced HCC now in pipeline.

BACKGROUND: Inflammation is a long-established hallmark of liver fibrosis and carcinogenesis. Eosinophils are emerging as crucial components of the inflammatory process influencing cancer development. The role of blood eosinophils in patients with hepatocellular carcinoma receiving systemic treatment is an unexplored field. OBJECTIVE: The objective of this study was to analyse the prognostic role of the baseline eosinophil count in patients with sorafenib-treated hepatocellular carcinoma. PATIENTS AND METHODS: A training cohort of 92 patients with advanced- or intermediate-stage sorafenib-treated hepatocellular carcinoma and two validation cohorts of 65 and 180 patients were analysed. Overall survival and progression-free survival in relation to baseline eosinophil counts were estimated by the Kaplan-Meier method. Univariate and multivariate analyses were performed. RESULTS: A negative prognostic impact of low baseline eosinophil counts (< 50*109/L) was demonstrated in all cohorts (training cohort: hazard ratio = 50.1, 95% confidence interval 11.6-216.5, p < 0.0001 for low vs high eosinophil counts; first validation cohort: hazard ratio = 4.55, 95% confidence interval 1.24-16.65, p = 0.022; second validation cohort: hazard ratio = 3.21, 95% confidence interval 1.83-5.64, p < 0.0001). Moreover, low eosinophil counts had a negative prognostic role in patients progressing on or intolerant to sorafenib who received second-line regorafenib, but not capecitabine or best supportive care. CONCLUSIONS: Our analysis identified baseline blood eosinophil counts as a new prognostic factor in patients with sorafenib-treated hepatocellular carcinoma. Concerning second-line therapies, eosinophil counts were associated with survival outcomes only in regorafenib-treated patients, suggesting a possible predictive role in this setting.
