Systemic Treatment of Recurrent Hepatocellular Carcinoma after Liver Transplantation: A Multicenter Trial.

INTRODUCTION: The tyrosine kinase inhibitors (TKIs) sorafenib and lenvatinib represent the first-line systemic therapy of choice for patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). Under sorafenib and lenvatinib, HCC patients have shown increasingly improved overall survival in clinical studies over the years. In contrast, data on overall survival for patients with HCC recurrence after LT under TKIs are scarce and limited to small retrospective series. In this retrospective, multicenter study, we investigated the efficacy of TKI therapy and the influence of immunosuppression in patients with HCC recurrence after LT. METHODS: Retrospective data were collected from four transplant centers from Germany and Austria. We included patients with HCC recurrence after LT between 2007 and 2020 who were treated with a TKI. RESULTS: In total, we analyzed data from 46 patients with HCC recurrence after LT. The most common underlying liver disease was hepatitis C, accounting for 52.2%. The median time to relapse was 11.8 months (range 0-117.7 months). The liver graft was affected in 21 patients (45.7%), and 36 patients (78.3%) had extrahepatic metastases at initial diagnosis of recurrence, with the lung being the most commonly affected (n = 25, 54.3%). Of the total, 54.3% (n = 25) of the patients were initially treated locally; 39 (85.8%) and 7 (15.2%) patients received sorafenib and lenvatinib, respectively, as first-line systemic therapy. Median overall survival of the whole cohort was 10.9 months (95% confidence interval (95% CI) 6.9-14.9 months) and median progression free survival was 5.7 months (95% CI 2.0-9.4 months) from treatment initiation. CONCLUSION: Since history of liver transplantation is considered a contraindication for immunotherapy, prognosis of patients with HCC recurrence after LT remains poor.

Adjuvant Treatment with S-1 in Patients after R0-Resection of Adenocarcinoma of the Stomach and Esophagogastric Junction: A Multicenter Phase I/II Feasibility Study (GMBH-STO-0114).

INTRODUCTION: S-1 has been shown to be an effective adjuvant treatment option for East Asian patients who underwent gastrectomy for stage II/III gastric cancer. We conducted a phase I/II study to evaluate the feasibility, tolerability, and efficacy of administering S-1 in the adjuvant setting after R0-resection of adenocarcinoma of the stomach and esophagogastric junction (EGJ) in Caucasian patients. METHODS: In this single-cohort, open-label, phase I/II trial, we enrolled patients with locally advanced adenocarcinoma of the stomach or EGJ having undergone R0-resection with or without neoadjuvant treatment. One treatment cycle consisted of oral S-1 (30 mg/m2 bid) for 14 days. Cycles were repeated every 3 weeks for 18 cycles (54 weeks). Primary endpoint was feasibility and tolerability. Safety was evaluated according to the Common Toxicity Criteria Adverse Events (CTCAE) version 4.0. Secondary endpoints were 1-year relapse-free survival (RFS) rate, RFS, and overall survival (OS). RESULTS: Between October 2015 and February 2018, 32 patients were enrolled in 12 German centers, and 30 started adjuvant study treatment. Seventeen patients completed all 18 cycles. Two patients terminated study treatment early due to adverse events (AEs), 7 due to patient's or investigator's decision, and 4 due to recurrence or distant metastasis during adjuvant therapy. Dose levels were reduced to 25 mg/m2 in 9 patients and to 20 mg/m2 in 1 patient. Of patients completing all 18 cycles, 5 did so with reduced dosage of S-1. Documented grade ≥3 AEs were neutropenia, diarrhea, vomiting, polyneuropathy, palmar-plantar erythrodysaesthesia, and rash. Serious AEs were observed in 7 patients. Median RFS was 32.2 months. One-year RFS rate was 77%. Data on OS were still premature at the end of the study. CONCLUSION: Adjuvant treatment with S-1 for 1 year is a feasible and safe treatment option for Caucasian patients diagnosed with gastric adenocarcinoma or cancer of the EGJ after R0-resection.

Retrospective Long-Term Evaluation of Conventional Transarterial Chemoembolization for Hepatocellular Carcinoma over 20 Years.

The aim of this study was to retrospectively evaluate the effects of conventional transarterial chemoembolization (cTACE) for the treatment of hepatocellular carcinoma over 20 years regarding overall survival (OS) and prognostic factors for OS. During the period from 1996 to 2016, 836 patients with HCC were treated with cTACE. Data evaluation was performed on the basis of pre- and postinterventional MRI and CT scans. Survival analysis was performed by Kaplan-Meier estimator; prognostic factors were determined by the use of Cox regression analysis. Overall, 4084 (mean 4.89 TACE sessions/patient) procedures were assessed. Median OS was 700 days (99% CI, 632.8-767.2). Depending on the indication, patients treated with a neoadjuvant intention showed the best OS (1229 days, 99% CI 983.8-1474.2) followed by curative intention (787 days, 99% CI 696.3-877.7), and then palliative intention (360 days, 99% CI 328.4-391.6). Portal vein thrombosis (HR 2.19, CI 1.63-2.96, and p < 0.01) and Child-Pugh class B or worse (HR 1.44, CI 1.11-1.86, and p < 0.001) were significantly associated with shorter OS. Patients with HCC benefit from TACE after careful patient selection. Portal vein thrombosis and Child-Pugh class B or worse are significantly unfavorable prognostic factors for patients' survival.

Baseline parenchymal blood volume is a potential prognostic imaging biomarker in patients with malignant liver tumors treated with transarterial chemoembolization.

PURPOSE: To assess the prognostic value of Parenchymal Blood Volume (PBV) in predicting survival, tumor response, and PBV response after transarterial chemoembolization (TACE). METHODS: A total of 137 patients with malignant liver tumors who were treated with TACE between 07/2016 and 07/2018 were evaluated. Computed tomography illustrations were reworked at a dedicated workstation to create a PBV map which was overlapped with the associated magnetic resonance image to determine tumor diameter and PBV. Patients were divided into two groups according to their initial PBV value: PBV < 50 or ≥ 50 ml/l. RESULTS: Retrospectively, for patients with at least 2 TACE and initial PBV < 50 ml/l (n = 27), the tumor volume, regardless of the primary tumor type, decreased by 13.26%, and PBV showed a decrease of 23.11%. For 84 patients with PBV ≥ 50 ml/l, the tumor volume decreased by 24.01%, and PBV showed a more substantial decrease of 44.69% (both p < 0.001). In the overall study population (n = 137), patients with an initial PBV ≥ 50 ml/l (n = 101) survived for an average of 15.05 months, while patients with an initial PBV < 50 ml/l (n = 36) survived for 10.01 months (p < 0.002). Subgroup analysis indicated that median survival in the HCC group was longer at PBV ≥ 50 ml/l. For CRC and other primary tumors, the survival time for high and low initial PBV was almost identical. CONCLUSION: Our study reveals a noteworthy correlation between high initial PBV values and a significant reduction in both relative and absolute tumor volume. This association suggests a potential prognostic indicator, indicating that elevated PBV may signify a more favorable response to transarterial chemoembolization (TACE). Additionally, patients with high initial PBV values experienced an extended overall survival time. Notably, the subgroup analysis highlighted a prolonged survival time in the HCC group with elevated initial PBV values. These findings underscore the potential significance of assessing PBV as a predictive factor in the context of TACE, especially in specific tumor entities such as HCC. Further investigations are essential to validate and extrapolate these observations to optimize patient outcomes.

Diagnostic performance of non-invasive liver fibrosis scores in patients with early-intermediate hepatocellular carcinoma.

PURPOSE: Hepatocellular carcinoma (HCC) arises in individuals with underlying liver disease. Diagnosing the degree of hepatic fibrosis helps to determine the severity of the underlying liver disease and may influence therapeutic decisions in HCC patients. Non-invasive fibrosis scores can be used to estimate the degree of fibrosis in liver disease patients, but most of these scores were developed in patients with viral hepatitis and without HCC. This study explored the ability of the Fibrosis-4 Index (FIB-4), the AST/Platelet Ratio Index (APRI), and the AST/ALT ratio to diagnose or exclude advanced fibrosis (METAVIR F3/4 versus F0-2) in patients with early-intermediate, potentially resectable HCC. METHODS: We retrospectively reviewed 119 patients who underwent hepatic resection for HCC at a tertiary centre (2007-2019), 75 of whom had advanced fibrosis (prevalence 63%). Histological assessment of the surgical liver specimen was used as a reference standard for the degree of fibrosis. RESULTS: Overall diagnostic performance was highest for the FIB-4 Index, with an area under the receiver operating characteristic curve (AUROC) of 0.82, compared with 0.78 for APRI, and 0.56 for the AST/ALT ratio. Using established cut-off values, FIB-4 achieved a 90% positive predictive value at the higher cut-off (3.25) and a 90% negative predictive value at the lower cut-off (1.45). CONCLUSION: The FIB-4 Index could reliably diagnose or exclude advanced fibrosis in patients with early-intermediate HCC, and may thus have a role in guiding therapeutic decisions in these patients.

Adjuvant Gemcitabine Versus Neoadjuvant/Adjuvant FOLFIRINOX in Resectable Pancreatic Cancer: The Randomized Multicenter Phase II NEPAFOX Trial.

BACKGROUND: Although addition of adjuvant chemotherapy is the current standard, the prognosis of pancreatic cancers still remains poor. The NEPAFOX trial evaluated perioperative treatment with FOLFIRINOX in resectable pancreatic cancer. PATIENTS AND METHODS: This multicenter phase II trial randomized patients with resectable or borderline resectable pancreatic cancer without metastases into arm (A,) upfront surgery plus adjuvant gemcitabine, or arm (B,) perioperative FOLFIRINOX. The primary endpoint was overall survival (OS). RESULTS: Owing to poor accrual, recruitment was prematurely stopped after randomization of 40 of the planned 126 patients (A: 21, B: 19). Overall, approximately three-quarters were classified as primarily resectable (A: 16, B: 15), and the remaining patients were classified as borderline resectable (A: 5, B: 4). Of the 12 evaluable patients, 3 achieved partial response under neoadjuvant FOLFIRINOX. Of the 21 patients in arm A and 19 patients in arm B, 17 and 7 underwent curative surgery, and R0-resection was achieved in 77% and 71%, respectively. Perioperative morbidity occurred in 72% in arm A and 46% in arm B, whereas non-surgical toxicity was comparable in both arms. Median RFS/PFS was almost doubled in arm B (14.1 months) compared with arm A (8.4 months) in the population with surgical resection, whereas median OS was comparable between both arms. CONCLUSIONS: Although the analysis was only descriptive owing to small patient numbers, no safety issues regarding surgical complications were observed in the perioperative FOLFIRINOX arm. Thus, considering the small number of patients, perioperative treatment approach appears feasible and potentially effective in well-selected cohorts of patients. In pancreatic cancer, patient selection before initiation of neoadjuvant therapy appears to be critical.

Systemic Drugs for Hepatocellular Carcinoma: What Do Recent Clinical Trials Reveal About Sequencing and the Emerging Complexities of Clinical Decisions?

Liver cancer was the fourth leading cause of cancer death in 2015 with increasing incidence between 1990 and 2015. Orthotopic liver transplantation, surgical resection and ablation comprise the only curative therapy options. However, due to the late manifestation of clinical symptoms, many patients present with intermediate or advanced disease, resulting in no curative treatment option being available. Whereas intermediate-stage hepatocellular carcinoma (HCC) is usually still addressable by transarterial chemoembolization (TACE), advanced-stage HCC is amenable only to pharmacological treatments. Conventional cytotoxic agents failed demonstrating relevant effect on survival also because their use was severely limited by the mostly underlying insufficient liver function. For a decade, tyrosine kinase inhibitor (TKI) sorafenib was the only systemic therapy that proved to have a clinically relevant effect in the treatment of advanced HCC. In recent years, the number of substances for systemic treatment of advanced HCC has increased enormously. In addition to tyrosine kinase inhibitors, immune checkpoint inhibitors (ICI) and antiangiogenic drugs are increasingly being applied. The combination of anti-programmed death ligand 1 (PD-L1) antibody atezolizumab and anti-vascular endothelial growth factor (VEGF) antibody bevacizumab has become the new standard of care for advanced HCC due to its remarkable response rates. This requires more and more complex clinical decisions regarding tumor therapy. This review aims at summarizing recent developments in systemic therapy, considering data on first- and second-line treatment, use in the neoadjuvant and adjuvant setting and combination with locoregional procedures.

Heterogeneity of small duct- and large duct-type intrahepatic cholangiocarcinoma.

AIMS: The histological subtype of intrahepatic cholangiocarcinoma (iCCA) is associated with different mutational characteristics that impact clinical management. So far, data are lacking on the presence of small duct iCCA (SD-iCCA) and large duct iCCA (LD-iCCA) in a single patient. The aim of the current study was to determine the presence and degree of intratumoural heterogeneity of SD- and LD-iCCA features in different tumour regions. METHODS AND RESULTS: All patients treated with surgically resected iCCA at Frankfurt University Hospital between December 2005 and March 2023 were retrospectively analysed. Histomorphological features of SD- and LD-iCCA were evaluated by an expert hepatobiliary pathologist. Tissue samples suspicious for subtype heterogeneity were further investigated. Immunohistochemistry for N-cadherin, S100P, MUC5AC, MUC6, TFF1 and AGR2 and mutational profiling with the Illumina TruSight Oncology 500 (TSO500) assay were performed separately for the SD- and LD-iCCA regions. Of 129 patients with surgically resected iCCA, features of either SD- or LD-iCCA were present in 67.4% (n = 87) and 24.8% of the patients (n = 32), respectively; 7.8% (n = 10) had histomorphological features of both SD- and LD-iCCA, seven patients (5.4%) of which had sufficient formalin-fixed, paraffin-embedded tissue for further analysis. Heterogeneity of both subtypes could be confirmed with immunohistochemistry. In five of seven (71.4%) patients, molecular profiling revealed intratumoural differences in genetic alterations between the SD- and LD-iCCA region. In one patient, a BRAF mutation (p.V600E) was found in the SD-iCCA but not in the LD-iCCA region of the tumour. CONCLUSIONS: A marked portion of patients with iCCA exhibits both SD- and LD-iCCA in different tumour regions. In case of the presence of histopathological heterogeneity, mutational profiling should be considered to avoid missing therapeutically relevant genetic alterations.

Development and clinical validation of a novel algorithmic score (GAAD) for detecting HCC in prospective cohort studies.

BACKGROUND: Alpha-fetoprotein (AFP) and des-gamma carboxyprothrombin (DCP), also known as protein induced by vitamin K absence-II (PIVKA-II [DCP]) are biomarkers for HCC with limited diagnostic value when used in isolation. The novel GAAD algorithm is an in vitro diagnostic combining PIVKA-II (DCP) and AFP measurements, age, and gender (biological sex) to generate a semi-quantitative result. We conducted prospective studies to develop, implement, and clinically validate the GAAD algorithm for differentiating HCC (early and all-stage) and benign chronic liver disease (CLD), across disease stages and etiologies. METHODS: Patients aged ≥18 years with HCC or CLD were prospectively enrolled internationally into algorithm development [n = 1084; 309 HCC cases (40.7% early-stage) and 736 controls] and clinical validation studies [n = 877; 366 HCC cases (47.6% early-stage) and 303 controls]. Serum samples were analyzed on a cobas® e 601 analyzer. Performance was assessed using receiver operating characteristic curve analyses to calculate AUC. RESULTS: For algorithm development, AUC for differentiation between early-stage HCC and CLD was 90.7%, 84.4%, and 77.2% for GAAD, AFP, and PIVKA-II, respectively. The sensitivity of GAAD for the detection of early-stage HCC was 71.8% with 90.0% specificity. Similar results were shown in the clinical validation study; AUC for differentiation between early-stage HCC and CLD was 91.4% with 70.1% sensitivity and 93.7% specificity. GAAD also showed strong specificity, with a lower rate of false positives regardless of disease stage, etiology, or region. CONCLUSIONS: The GAAD algorithm significantly improves early-stage HCC detection for patients with CLD undergoing HCC surveillance. Further phase III and IV studies are warranted to assess the utility of incorporating the algorithm into clinical practice.

The Diagnosis and Treatment of Ampullary Carcinoma.

BACKGROUND: Ampullary or papillary carcinoma is a malignant tumor arising from the mucosa in the region of the major duodenal papilla, also known as the ampulla of Vater. Uniform treatment recommendations are lacking both for the adjuvant situation and for palliative care. METHODS: A selective literature search was carried out in PubMed in order to identify the most informative publications concerning the epidemiology, clinico-pathological background, and surgical and medical treatment of this condition. RESULTS: Ampullary carcinoma has an incidence of 0.5 to 0.9 per 100 000 persons and a poor prognosis, with a 5-year survival rate of 41% to 45% for locally confined and 4% to 7% for metastatic disease. Most such tumors are of an intestinal or a pan - creaticobiliary immunohistochemical subtype; the latter has a worse prognosis (median survival, 72-80 vs. 33-41 months). Targeted treatment is not yet available for either subtype, nor is there enough scientific evidence available for the formulation of specific therapeutic recommendations in either the adjuvant or the palliative situation. The treatment of choice for ampullary carcinoma is radical oncological resection of the head of the pancreas with systematic lymphadenectomy. Five-year overall survival is between 10% and 75% depending on the stage. No definitive recommendation for adjuvant therapy can be given. Palliative therapy can be oriented to the published treatment strategies for cancer of the colon, pancreas, and bile duct. CONCLUSION: The current state of the evidence on the treatment of ampullary carcinoma is poor. Therapeutic decisions should be discussed in an interdisciplinary tumor board and should, in our opinion, take the histological subtype into account.

Active Autophagy Is Associated with Favorable Outcome in Patients with Surgically Resected Cholangiocarcinoma.

Data on the impact of autophagy in primary cholangiocarcinoma (CCA) remain scarce. Here, we therefore investigated the role of active autophagy and its impact on survival in CCA patients. All CCA patients who underwent surgical resection with curative intent between 08/2005 and 12/2021 at University Hospital Frankfurt were evaluated. Autophagic key proteins were studied by immunohistochemistry. iCCA processed for gene expression profiling of immune-exhaustion gene sets was used for an autophagy approach in silico. Active autophagy was present in 23.3% of the 172 CCA patients. Kaplan-Meier curves revealed median OS of 68.4 months (95% CI = 46.9-89.9 months) and 32.7 months (95% CI = 23.6-41.8 months) for active and non-active autophagy, respectively (p ≤ 0.001). In multivariate analysis, absence of active autophagy (HR = 2, 95% CI = 1.1-3.5, p = 0.015) was an independent risk factor for OS. Differential-expression profiling revealed significantly upregulated histone deacetylases (HDAC) mRNA in patients showing non-active autophagy. In line with this, pan-acetylated lysine was significantly more prominent in CCA patients with ongoing autophagy (p = 0.005). Our findings strengthen the role of active autophagy as a prognostically relevant marker and a potential therapeutic target.

Chemotherapy and Targeted Therapy Strategies in Patients with Unresectable or Borderline Resectable Metastatic Colorectal Cancer: Evidence for a Lack of Focus on Resection Rates.

BACKGROUND AND AIMS: Chemotherapy (CTx) with targeted therapy (TT) have increased the overall response rate (ORR) and improved survival in unresectable or borderline resectable metastatic colorectal cancer (mCRC). However, the resection rate is an endpoint with often suboptimal expert involvement. The aim was to investigate whether the improvements in ORR have translated to improved resection rates (RR). STUDY DESIGN: A systematic literature search was performed using the PICO process. STATISTICAL ANALYSIS: Odds ratios, and 95% confidence intervals (OR, 95% CI) were analyzed for ORR and RR using dichotomous values with the Mantel-Haenszel method. Progression-free survival (PFS) and overall survival (OS) were analyzed using the inverse-variance method and displayed as hazard ratios and 95% confidence intervals (HR, 95% CI). RESULTS: The literature search returned 469 records. Sixteen articles with 5724 patients were selected for analysis. The qualitative analysis revealed low and moderate risk of bias endpoints. Higher ORR was observed with CTx + TT versus CTx only (OR: 0.62 [95% CI 0.45; 0.82], p = 0.002) and with triplet CTx + TT versus doublet CTx + TT (OR: 0.61 [95% CI 0.46; 0.81], p < 0.001). PFS and OS were improved by use of TT (HR: 0.68-0.84; p < 0.001 to 0.04). The overall RR was low (< 15%) and did not improve in the same way as the other endpoints. CONCLUSION: The ORR and survival rates in unresectable and borderline resectable mCRC were improved by modern CTx and TT that did not translate into higher RR, mostly due to the lack of expert involvement.

Phase 2 trial of bintrafusp alfa as second-line therapy for patients with locally advanced/metastatic biliary tract cancers.

BACKGROUND AND AIMS: Biliary tract cancers are rare, heterogeneous cancers with poor prognoses. Bintrafusp alfa, a first-in-class bifunctional fusion protein composed of the extracellular domain of TGF-ßRII (a TGF-ß "trap") fused to a human IgG1 monoclonal antibody blocking programmed death ligand 1, was evaluated in patients with locally advanced/metastatic chemorefractory biliary tract cancers. APPROACH AND RESULTS: This multicenter, single-arm, open-label, phase 2 study (NCT03833661) enrolled adults with locally advanced or metastatic biliary tract cancer that was intolerant to or had failed first-line systemic platinum-based chemotherapy. Patients received 1200 mg bintrafusp alfa intravenously Q2W. The primary endpoint was confirmed objective response according to Response Evaluation Criteria in Solid Tumors 1.1 assessed by IRC. Secondary endpoints included duration of response, durable response rate, safety, progression-free survival, and overall survival.Between March 2019 and January 2020, 159 patients were enrolled. Median follow-up was 16.1 (range, 0.0-19.3) months; 17 patients (10.7%; 95% CI: 6.4%-16.6%) achieved an objective response. Median duration of response was 10.0 (range, 1.9-15.7) months; 10 patients (6.3%; 95% CI: 3.1%-11.3%) had a durable response (≥6 mo). Median progression-free survival was 1.8 months (95% CI: 1.7-1.8 mo); median overall survival was 7.6 months (95% CI: 5.8-9.7 mo). Overall survival rates were 57.9% (6 mo) and 38.8% (12 mo). Grade ≥3 adverse events occurred in 26.4% of patients, including one treatment-related death (hepatic failure). Frequent grade ≥3 adverse events included anemia (3.8%), pruritus (1.9%), and increased alanine aminotransferase (1.9%). CONCLUSIONS: Although this study did not meet its prespecified primary endpoint, bintrafusp alfa demonstrated clinical activity as second-line treatment in this hard-to-treat cancer, with durable responses and a manageable safety profile.

Impact of IDH1 mutation on clinical course of patients with intrahepatic cholangiocarcinoma: a retrospective analysis from a German tertiary center.

PURPOSE: IDH1 mutation is a known biomarker for targeted therapy of intrahepatic cholangiocarcinoma (iCCA), while its prognostic relevance for current palliative chemotherapy is still unclear. Aim of this study was to analyze clinicopathological characteristics of patients with IDH1 mutations and to outline a potential impact on the outcome after state-of-the-art palliative chemotherapy regimens. METHODS: All patients with iCCA receiving large panel molecular profiling and follow-up treatment at Frankfurt University Hospital until 04/2022 were retrospectively analyzed. Clinicopathological characteristics were assessed for IDH1 mutated (mut) and IDH1 wild type (wt) patients, and progression-free survival (PFS) and overall survival (OS) were determined. RESULTS: In total, 75 patients with iCCA received molecular profiling. Of the patients with available DNA data, pathogenic mutations in IDH1 were found in 14.5% (n = 10). IDH1 mut status was associated with lower serum CA-19/9 (p = 0.023), lower serum lactate dehydrogenase (p = 0.006), and a higher proportion of primary resectability (p = 0.028) as well as response to chemotherapy after recurrence (p = 0.009). Median PFS was 5.9 months (95% CI 4.4-7.3 months) for IDH1 wt in comparison to 9.8 months (95% CI 7.7-12 months) for patients with IDH1 mut (p = 0.031). IDH1 wt was a significant risk factor for shortened PFS in univariate (p = 0.043), but not in multivariate analysis (p = 0.061). There was no difference in OS between both groups. CONCLUSION: Patients with IDH1 mutated iCCA seem to have a favorable tumor biology including a longer PFS for palliative chemotherapy regimens compared to IDH1 wild type.

Liver resection after Transjugular Portosystemic Stent Shunt (TIPSS).

Hepatocellular carcinoma (HCC) often arises in cirrhotic livers. Generally, decompensated liver cirrhosis is a contraindication to surgery. Even in compensated liver cirrhosis, liver resection for HCC carries a high risk of post-hepatectomy liver failure and decompensation of cirrhosis. Thus, in current staging systems such as the Barcelona Classification of Liver Cancer (BCLC) or the Hong Kong Classification of Liver Cancer (HKLC), liver resection is limited to smaller tumors in compensated cirrhosis. While transjugular portosystemic stent shunts (TIPSS) are widely used for the treatment of complications of portal hypertension such as recurrent esophageal bleeding or refractory ascites, the presence of a TIPSS is generally considered a contraindication for liver resection. Herein, we describe - to our knowledge for the first time - liver resection of an intermediate HCC with a diameter of 11 cm in a patient who had previously received a TIPSS for decompensated cirrhosis. With open surgery, radical resection (R0) was able to be achieved, and the patient left the hospital after 6 days following an uncomplicated postoperative course. Thus, in highly selected cases, liver resection following TIPSS may be considered.

Colonization with multidrug-resistant organisms is associated with impaired survival of patients with surgically resected cholangiocarcinoma.

BACKGROUND & AIMS: Colonization with multidrug-resistant organisms (MDRO) has been shown to impair survival in patients with various malignancies. Despite the increasing spread of MDRO, its impact on patients with cholangiocarcinoma (CCA) is unclear. Aim of this study was to analyse the impact of MDRO-colonization on overall prognosis in CCA patients. METHODS: All patients with surgically resected CCA diagnosed between August 2005 and November 2021 at the University Hospital Frankfurt were screened for MDRO. CCA patients with a positive MDRO screening before or within the first 90 days after diagnosis of CCA were defined as colonized. Patients with a negative MDRO screening were defined as non-colonized. RESULTS: Hundred and sixty nine patients were included. 32% (n = 54) were screened MDRO positive, while 68% (115) were non-colonized. Median overall survival (OS) for colonized patients was 17.1 months (95% CI = 9-25.2 months) compared to 50 months (95% CI = 37.1-62.8) for MDRO-negative patients (p ≤ .001). Non-cancer-related mortality (p ≤ .001) and infectious-related death (p ≤ .001) was significantly higher in the MDRO-colonized group. In multivariate analysis, MDRO colonization (HR = 2.1, 95% CI = 1.4-3.3, p = .001), ECOG 1 (HR = 2.5, 95% CI = 1.6-4, p ≤ .001) and N1 status (HR = 1.7, 95% CI = 1.1-2.6, p = .017) were independent risk factors for OS. CONCLUSION: MDRO-colonization contributes to poor survival in patients with surgically resected CCA. MDRO surveillance is necessary to optimize clinical management of infections and to potentially reduce mortality in this critical population.
