We have read with interest the paper by Gerbes et al,1 which highlights the current developments in the treatment of hepatocellular carcinoma (HCC). Fibrolamellar HCC (FL-HCC) is, in contrast to HCC,2 an infrequent tumour, most often occurring in adolescents or young adults without underlying liver disease.3 Chemotherapy-based regimens are typically used to treat FL-HCC based on studies in small patients’ cohorts and case series.3 Despite anecdotal reports of response to systemic treatment, the prognosis of advanced FL-HCC is poor.4

Introduction Immune checkpoint inhibitor (ICI)-based regimens are transforming the landscape of hepatocellular carcinoma (HCC) treatment. We describe the effect of combined ipilimumab and nivolumab in patients with advanced HCC after the failure of prior ICI-based combination treatments. Methods The clinical course of patients with advanced HCC who received combined ipilimumab and nivolumab after prior ICI-based combination therapies was assessed. Progression-free survival (PFS), overall response rate (ORR) and disease control rate (DCR) per RECIST v1.1 and mRECIST, overall survival (OS), and safety were analyzed. Results Of 109 patients treated with atezolizumab and bevacizumab or other ICI-based combination treatments, ten patients received subsequent therapy with ipilimumab and nivolumab. The majority of patients had Barcelona Clinic Liver Cancer (BCLC) Stage C (80%) HCC and a preserved liver function as defined by Child–Pugh A (80%). At a median follow-up of 15.3 months, ORR for ipilimumab and nivolumab was 30% with a DCR of 40%. Median PFS was 2.9 months and the median OS was 7.4 months. Conclusion This retrospective study demonstrates that combined ipilimumab and nivolumab can be effective and tolerable after prior ICI-based combination therapies and provides a rationale for the prospective clinical evaluation of this treatment sequencing.

Objective: Evaluation of the efficacy and safety of atezolizumab/bevacizumab in a real-world HCC cohort, including patients with impaired liver function and prior systemic therapy. Methods: Retrospective analysis of 147 HCC patients treated with atezolizumab/bevacizumab at six sites in Germany and Austria. Results: The overall response rate and disease control rate were 20.4% and 51.7%, respectively. Seventy-three patients (49.7%) met at least one major exclusion criterion of the IMbrave150 trial (IMbrave-OUT), whereas 74 patients (50.3%) were eligible (IMbrave-IN). Median overall survival (mOS) as well as median progression-free survival (mPFS) was significantly longer in IMbrave-IN versus IMbrave-OUT patients [mOS: 15.0 months (95% confidence interval (CI): 10.7–19.3] versus 6.0 months (95% CI: 3.2–8.9; p < 0.001) and mPFS: 8.7 months (95% CI: 5.9–11.5) versus 3.7 months (95% CI: 2.7–4.7; p < 0.001)]. Prior systemic treatment did not significantly affect mOS [hazard ratio (HR): 1.32 (95% CI: 0.78–2.23; p = 0.305)]. mOS according to ALBI grades 1/2/3 were 15.0 months (95% CI: not estimable), 8.6 months (95% CI: 5.4–11.7), and 3.2 months (95% CI: 0.3–6.1), respectively. ALBI grade and ECOG score were identified as independent prognostic factors [ALBI grade 2 versus 1; HR: 2.40 (95% CI: 1.34 – 4.30; p = 0.003), ALBI grade 3 versus 1; HR: 7.28 (95% CI: 3.30–16.08; p < 0.001), and ECOG ⩾2 versus 0; HR: 2.09 (95% CI: 1.03 – 4.23; p = 0.042)], respectively. Sixty-seven patients (45.6%) experienced an adverse event classified as CTCAE grade ⩾3. Patients in the IMbrave-OUT group were at increased risk of hepatic decompensation with encephalopathy (13.7% versus 1.4%, p = 0.004) and/or ascites (39.7% versus 9.5%; p < 0.001). Conclusion: In this real-world cohort, efficacy was comparable to the results of the IMbrave150 study and not affected by prior systemic treatment. ALBI grade and ECOG score were independently associated with survival. IMbrave-OUT patients were more likely to experience hepatic decompensation.

Immune checkpoint inhibitors (ICIs) belong to the therapeutic armamentarium in advanced hepatocellular carcinoma (HCC). However, only a minority of patients benefit from immunotherapy. Therefore, we aimed to identify indicators of therapy response. This multicenter analysis included 99 HCC patients. Progression-free (PFS) and overall survival (OS) were studied by Kaplan-Meier analyses for clinical parameters using weighted log-rank testing. Next-generation sequencing (NGS) was performed in a subset of 15 patients. The objective response (OR) rate was 19% median OS (mOS)16.7 months. Forty-one percent reached a PFS > 6 months; these patients had a significantly longer mOS (32.0 vs. 8.5 months). Child-Pugh (CP) A and B patients showed a mOS of 22.1 and 12.1 months, respectively. Ten of thirty CP-B patients reached PFS > 6 months, including 3 patients with an OR. Tumor mutational burden (TMB) could not predict responders. Of note, antibiotic treatment within 30 days around ICI initiation was associated with significantly shorter mOS (8.5 vs. 17.4 months). Taken together, this study shows favorable outcomes for OS with low AFP, OR, and PFS > 6 months. No specific genetic pattern, including TMB, could identify responders. Antibiotics around treatment initiation were associated with worse outcome, suggesting an influence of the host microbiome on therapy success.

Cross-sector development partnerships (CSDPs) are project-based collaborative arrangements between business, government, and civil society organizations in support of international development goals such as sustainability, health education, and economic development. Focusing on public private partnerships in development cooperation, we examine different constellations of bridging agents and their effects in the formation of single CSDP projects and longer-term alliances. We conceptualize bridging agency as a collective process involving both internal partner representatives and external intermediaries in initiating and/or supporting roles. We find that the involvement of external intermediaries eases the formation of single projects and longer-term alliances. However, when projects are initiated by external intermediaries they tend to be repetitive and narrow in scope, whereas projects initiated by internal partner representatives often explore novel agendas and embody a greater potential for social innovation. Yet, the longer-term pursuit of these agendas beyond single projects may require external intermediaries in supporting roles. Findings help better understand microprocesses and collective practices of brokerage and alliance formation in transnational governance contexts and beyond.

Background and ObjectiveWith the rising importance of precision oncology in biliary tract cancer (BTC), the aim of this retrospective single-center analysis was to describe the clinical and molecular characteristics of patients with BTC who underwent comprehensive genomic profiling (CGP) and were discussed in the CCCMunichLMU molecular tumor board (MTB).Patients and MethodsIn this single-center observational study, we included BTC patients with intrahepatic cholangiocarcinoma (iCCA), extrahepatic CCA (eCCA), and gallbladder cancer (GB), who had been discussed in the institutional MTB from May 29, 2017, to July 25, 2022. Patients were followed up until 31 January 2023. Data were retrospectively collected by review of medical charts, and MTB recommendation.ResultsIn total, 153 cases were registered to the MTB with a median follow-up of 15 months. Testing was successful in 81.7% of the patients. CGP detected targetable alterations in 35.3% of our BTC patients (most commonly ARID1A/ERBB2/IDH1/PIK3CA/BRAF-mutations and FGFR2-fusions). Recommendations for molecularly guided therapy were given in 46.4%. Of those, treatment implementation of targeted therapy followed in 19.4%. In patients receiving the recommended treatment, response rate was 57% and median overall survival was 19 months (vs 8 months in the untreated cohort). The progression-free survival ratio of 1.45 suggest a clinical benefit of molecularly guided treatment.ConclusionsIn line with previous work, our series demonstrates feasibility and clinical utility of comprehensive genomic profiling in BTC patients. With the growing number of targeted agents with clinical activity in BTC, CGP should become standard of care in the management of this group of patients.

Reliable and effective control systems are a critical component of safe and profitable operations across process industries. And many of our industrial facilities today continue to operate using legacy control systems from the past four decades that are at or near the end of their lifecycles. Migration projects to modern control systems are complex, requiring detailed upfront planning, a methodical implementation strategy and astute project management.

The optimal treatment sequence of tyrosine kinase inhibitor (TKI)-based therapy in patients with hepatocellular carcinoma (HCC) remains unclear. Therefore, sequential systemic therapy after first-line therapy with sorafenib or lenvatinib was compared in a retrospective real-world cohort. In total, 164 patients with HCC were included. Child B cirrhosis was present in 26 patients (16.5%), whereas 132 patients (83.5%) had preserved liver function. In total, 72 patients (44%) discontinued systemic therapy after first-line therapy while 51 (31%) and 31 (19%) patients received 2 or more treatment lines. Most notably, median overall survival (mOS) was influenced by liver functional status and patient performance status at the beginning of first-line therapy. Patients receiving a sequential therapy regimen had significantly longer mOS compared to patients that discontinued systemic therapy after omitting first-line treatment. The choice of the initial TKI did not impact mOS. A clear deterioration of liver function could be observed during the course of TKI-based treatment.

PurposeGadoxetic acid uptake on hepatobiliary phase MRI has been shown to correlate with ß-catenin mutation in patients with HCC, which is associated with resistance to certain therapies. This study aimed to evaluate the prognostic value of gadoxetic acid uptake on hepatobiliary phase MRI in patients with advanced HCC receiving sorafenib.Methods312 patients with available baseline hepatobiliary phase MRI images received sorafenib alone or following selective internal radiation therapy (SIRT) within SORAMIC trial. The signal intensity of index tumor and normal liver parenchyma were measured on the native and hepatobiliary phase MRI images, and relative tumor enhancement higher than relative liver enhancement were accepted as high gadoxetic acid uptake, and its prognostic value was assessed using univariate and multivariate Cox proportional hazard models.ResultsThe median OS of the study population was 13.4 (11.8–14.5) months. High gadoxetic acid uptake was seen in 51 (16.3%) patients, and none of the baseline characteristics was associated with high uptake.In univariate analysis, high gadoxetic acid uptake was significantly associated with shorter overall survival (10.7 vs. 14.0 months, p = 0.005). Multivariate analysis confirmed independent prognostic value of high gadoxetic acid uptake (HR, 1.7 [1.21–2.3], p = 0.002), as well as Child–Pugh class (p = 0.033), tumor diameter (p = 0.002), and ALBI grade (p = 0.015).ConclusionIn advanced HCC patients receiving sorafenib (alone or combined with SIRT), high gadoxetic acid uptake of the tumor on pretreatment MRI, a surrogate of ß-catenin mutation, correlates with shorter survival. Gadoxetic acid uptake status might serve in treatment decision-making process.

Background and aims Prognostic biomarkers identifying patients with early tumor progression after local ablative therapy remain an unmet clinical need. The aim of this study was to investigate circulating miR-21 and miR-210 levels as prognostic biomarkers of HCC treated by CT-guided high-dose rate brachytherapy (HDR-BT). Materials and Methods 24 consecutive HCC patients (BCLC A and B) treated with CT-guided HDR-BT (1 × 15 Gy) were included in this prospective IRB-approved study. RT-PCR was performed to quantify miR-21 and miR-210 levels in blood samples acquired prior to and 2 d after HDR-BT. Follow-up imaging (contrast-enhanced liver MRI and whole-body CT) was performed in 3 months follow-up intervals. Therapy response was assessed with patients classified as either responders or non-responders (12 each). Responders were defined as having no local or diffuse systemic progression within 6 months and no diffuse systemic progression exceeding 3 nodules/nodule diameter > 3 cm from 6 months to 2 years. Non-responders had recurrence within 6 months and/or tumor progression with > 3 nodules or individual lesion diameter > 3 cm or extrahepatic disease within two years, respectively. Biostatistics included parametric and non-parametric testing (Mann–Whitney-U-test), as well as Kaplan–Meier curve construction. Results The responder group demonstrated significantly decreasing miR-21 values 2 d post therapy compared to non-responders (median miR-21 2 −ΔΔCт : responders 0.73 [IQR 0.34], non-responders 1.53 [IQR 1.48]; p  = 0.0102). miR-210 did not show any significant difference between responders and non-responders (median miR-210 2 −ΔΔCт : responders 0.74 [IQR 0.45], non-responders 0.99 [IQR 1.13]; p  = 0.8399). Kaplan–Meier curves demonstrated significantly shorter time to systemic progression for increased miR-21 ( p  = 0.0095) but not miR-210 ( p  = 0.7412), with events accumulating > 1 year post therapy in non-responders (median time to systemic progression 397 days). Conclusion Increasing circulating miR-21 levels are associated with poor response and shorter time to systemic progression in HDR-BT-treated HCC. This proof-of-concept study provides a basis for further investigation of miR-21 as a prognostic biomarker and potential stratifier in future clinical trials of interventional oncology therapies. Trial registration: In this monocentric clinical study, we analyzed prospectively acquired data of 24 patients from the “ESTIMATE” patient cohort (Studiennummer: DRKS00010587, Deutsches Register Klinischer Studien). Ethical approval was provided by the ethics committee “Ethikkommission bei der LMU München” (reference number “17-346”) on June 20, 2017 and August 26, 2020.
