The European Society for Medical Oncology (ESMO) annual meeting in Madrid in October 2023 showcased advancements in gastroesophageal oncology. Several studies were presented, including the SANO trial, which found that active surveillance after neoadjuvant chemoradiotherapy could be an alternative to standard resection for patients with locally advanced esophageal cancer. The Keynote-585 study explored the addition of pembrolizumab to perioperative chemotherapy for gastroesophageal adenocarcinoma and found improved response rates and event-free survival. The Matterhorn study showed that adding durvalumab to perioperative chemotherapy increased response rates in gastroesophageal cancer. Additionally, the Keynote-811 trial demonstrated that pembrolizumab improved progression-free survival in HER2-positive advanced gastroesophageal adenocarcinoma. The text also discussed trials evaluating treatments for HER2-negative metastatic gastric or gastroesophageal junction cancer, including pembrolizumab, sugemalimab, and zolbetuximab, which all showed promising results in improving survival and response rates. These findings provide potential treatment options for patients with HER2-negative mGC/GEJC. [Extracted from the article]

The document discusses various clinical trials and studies related to these types of cancer. For localized pancreatic cancer, the PREOPANC-2 trial compared different treatment approaches and found that gemcitabine-based chemoradiotherapy was more effective than neoadjuvant FOLFIRINOX. In advanced pancreatic cancer, the JCOG1611-GENERATE trial showed that nab-paclitaxel plus gemcitabine was more effective than modified FOLFIRINOX or S-IROX. The document also mentions studies on hepatocellular carcinoma and cholangiocellular cancer, highlighting the use of targeted therapies. Overall, the document provides valuable information for researchers and healthcare professionals interested in these areas of oncology. [Extracted from the article]

Background and Aims: Combination atezolizumab/bevacizumab is the gold standard for first‐line treatment of unresectable hepatocellular carcinoma (HCC). Our study investigated the efficacy and safety of combination therapy in older patients with HCC. Methods: 191 consecutive patients from eight centres receiving atezolizumab and bevacizumab were included. Overall survival (OS), progression‐free survival (PFS), overall response rate (ORR) and disease control rate (DCR) defined by RECIST v1.1 were measured in older (age ≥ 65 years) and younger (age < 65 years) age patients. Treatment‐related adverse events (trAEs) were evaluated. Results: The elderly (n = 116) had higher rates of non‐alcoholic fatty liver disease (19.8% vs. 2.7%; p <.001), presenting with smaller tumours (6.2 cm vs 7.9 cm, p =.02) with less portal vein thrombosis (31.9 vs. 54.7%, p =.002), with fewer patients presenting with BCLC‐C stage disease (50.9 vs. 74.3%, p =.002). There was no significant difference in OS (median 14.9 vs. 15.1 months; HR 1.15, 95% CI 0.65–2.02 p =.63) and PFS (median 7.1 vs. 5.5 months; HR 1.11, 95% CI 0.54–1.92; p =.72) between older age and younger age. Older patients had similar ORR (27.6% vs. 20.0%; p =.27) and DCR (77.5% vs. 66.1%; p =.11) compared to younger patients. Atezolizumab‐related (40.5% vs. 48.0%; p =.31) and bevacizumab‐related (44.8% vs. 41.3%; p =.63) trAEs were comparable between groups. Rates of grade ≥3 trAEs and toxicity‐related treatment discontinuation were similar between older and younger age patients. Patients 75 years and older had similar survival and safety outcomes compared to younger patients. Conclusions: Atezolizumab and bevacizumab therapy is associated with comparable efficacy and tolerability in older age patients with unresectable HCC. [ABSTRACT FROM AUTHOR]

Background Lenvatinib is approved as first-line treatment for patients with advanced hepatocellular carcinoma (HCC). The efficacy of lenvatinib in Caucasian real-world patients is insufficiently defined. The purpose of this study was to evaluate the efficacy of lenvatinib in a multi-center cohort (ELEVATOR) from Germany and Austria. Methods A retrospective data analysis of 205 patients treated with first-line systemic lenvatinib at 14 different sites was conducted. Overall survival, progression free survival, overall response rate and adverse event rates were assessed and analyzed. Results Patients receiving lenvatinib in the real-world setting reached a median overall survival of 12.8 months, which was comparable to the results reported from the REFLECT study. Median overall survival (mOS) and progression free survival (mPFS) was superior in those patients who met the inclusion criteria of the REFLECT study compared to patients who failed to meet the inclusion criteria (mOS 15.6 vs 10.2 months, HR 0.55, 95% CI 0.38-0.81, p=0.002; mPFS 8.1 vs 4.8 months HR 0.65, 95% CI 0.46-0.91, p=0.0015). For patients with an impaired liver function according to the Albumin-Bilirubin (ALBI) grade, or reduced ECOG performance status ≥2, survival was significantly shorter compared to patients with sustained liver function (ALBI grade 1) and good performance status (ECOG performance status 0), respectively (HR 1.69, 95% CI 1.07-2.66, p=0.023; HR 2.25, 95% CI 1.19-4.23, p=0.012). Additionally, macrovascular invasion (HR 1.55, 95% CI 1.02-2.37, p=0.041) and an AFP ≥200 ng/mL (HR 1.56, 95% CI 1.03-2.34, p=0.034) were confirmed as independent negative prognostic factors in our cohort of patients with advanced HCC. Conclusion Overall, our data confirm the efficacy of lenvatinib as first-line treatment and did not reveal new or unexpected side effects in a large retrospective Caucasian real-world cohort, supporting the use of lenvatinib as meaningful alternative for patients that cannot be treated with IO-based combinations in first-line HCC.

The combination of the anti-PD-L1 antibody atezolizumab and the anti-VEGF bevacizumab is the first approved immunotherapeutic regimen for first-line therapy in patients with unresectable hepatocellular carcinoma (HCC), currently approved in more than 80 countries. The efficacy and tolerability of this regimen suggest that the use of atezolizumab + bevacizumab could be extended to the treatment of patients with intermediate-stage HCC in combination with transarterial chemoembolization (TACE). The authors describe the rationale and design of the DEMAND study. This investigator-initiated, multicenter, randomized phase II study is the first trial to evaluate the safety and efficacy of atezolizumab + bevacizumab prior to or in combination with TACE in patients with intermediate-stage HCC. The primary end point is the 24-month survival rate; secondary end points include objective response rate, progression-free survival, safety and quality of life. Clinical Trial Registration: NCT04224636 (ClinicalTrials.gov). [ABSTRACT FROM AUTHOR]

Background and aims: Patients with liver cirrhosis (LC) are considered to be at increased risk for mortality when acquiring SARS-CoV-2 infection and subsequently developing Corona Virus Disease 2019 (COVID-19). During the COVID-19 pandemic, hospitals are regarded as sites with increased risk of infection. Therefore, patient contacts are often limited to urgent indications, which could negatively affect disease monitoring. However, data regarding actual infection rates in cirrhotic patients is limited. The aim of this prospective study was to assess the incidence of COVID-19 in patients with LC with/without hepatocellular carcinoma (HCC) with physical presentation at our University Medical Center. Methods: Patients were enrolled between 1st April and 30th June 2020 at the University Medical Center Hamburg-Eppendorf, Germany. Symptoms of upper airway infection at baseline and presence of SARS-CoV-2 antibodies (IgG/IgM/IgA) were assessed at baseline and follow-up (FU) using an Electro-chemiluminescence immunoassay (Roche Elecsys). FU visits, including liver function test, clinical assessment and symptom questionnaire, were conducted after 6–8 weeks (FU-1) and 6 months (FU-2). Prior to inclusion of the first patient, obligatory face masks and personal distance were implemented as protective measures. Results: A total of 150 patients were enrolled, 23% (n = 35) also had diagnosis of HCC (median age: 64 years, range: 19–86), 69% were male. Liver function according to Child-Pugh score (CPS) was: CPS A: 46% (n = 62); CPS B: 37% (n = 50); CPS C: 17% (n = 23). Clinical symptoms indicating upper airway infection were present in 53% (n = 77): shortness of breath (n = 40) and coughing (n = 28) were the most frequent. For the 150 patients enrolled, 284 outpatient visits were registered and 33 patients were admitted to the University Medical Center during the follow-up period. After a median of 52 days, n = 110 patients completed FU-1 and n = 72 completed FU-2 after a median of 6.1 months. Only in one patient, an 80-year-old man with stable liver function (CPS A) and advanced HCC, SARS-CoV-2 antibodies were detected at baseline and FU-1, while antibody testing was negative in the remaining patients at baseline, FU-1 and FU-2. Conclusion: The incidence of COVID-19 at our tertiary medical center during the pandemic was low in LC and HCC patients, when simple protective measures were implemented. Therefore, a routine care for patients with chronic liver diseases does not increase the risk of SARS-CoV-2 infection and should be maintained with protective measures. [ABSTRACT FROM AUTHOR]

Background and Aims: The multikinase inhibitor cabozantinib has been approved for hepatocellular carcinoma (HCC) previously treated with sorafenib. We report safety and efficacy data of an international, multicenter, real-life cohort of patients with advanced HCC treated with cabozantinib. Methods: Patients with HCC who were treated with cabozantinib were retrospectively identified across 11 centers in Austria, Switzerland, and Germany. Patients' characteristics, adverse events, duration of treatment and overall survival (OS) data were analyzed until April 1, 2020. Results: Eighty-eight patients from 11 centers were included. The predominant underlying liver diseases were NAFLD/NASH in 26 (30%) and hepatitis C infection in 21 (24%) patients. Seventy-eight patients (89%) were classified as Barcelona clinic liver cancer (BCLC) stage C. Sixty patients (68%) were Child-Pugh A, whereas 22 (25%) were Child-Pugh B, respectively. Cabozantinib was used as systemic second- and third-line or later treatment in 41 (47%) and 46 (52%) patients, respectively. The following best responses under cabozantinib were documented: partial response in 6 (7%), stable disease in 28 (32%), and progressive disease in 28 (32%) patients, respectively. Fifty-two patients (59%) died during follow-up. The median OS from start of cabozantinib treatment was 7.0 months in the entire cohort and 9.7 months in Child-Pugh A patients, while Child-Pugh B patients had a median OS of 3.4 months, respectively. Thirty-seven (42%) patients fulfilled the CELESTIAL inclusion and exclusion criteria, showing a median OS of 11.1 months. Most common adverse events were fatigue (15.6%) and diarrhea (15.6%). Conclusion: Cabozantinib treatment was effective, safe, and feasible in patients with advanced HCC in patients with compensated cirrhosis. Patients in the real-life setting had more advanced liver disease – in which 25% of patients were Child-Pugh B. However, OS in patients with Child-Pugh A cirrhosis was similar to that reported in the phase 3 trial (CELESTIAL). [ABSTRACT FROM AUTHOR]

Summary: Background: Programmed cell death protein‐1‐targeted immunotherapy has shown promising results in phase II studies of hepatocellular carcinoma. Aim: To evaluate safety and efficacy of nivolumab and pembrolizumab in an international, multicentre, real‐world cohort of patients with advanced hepatocellular carcinoma. Methods: Sixty‐five patients treated with nivolumab (n = 34) or pembrolizumab (n = 31) between July 10, 2015 and December 31, 2018 (data cut‐off) across six centres in Austria and Germany were retrospectively analysed. Results: Child‐Pugh class A/B/C was 32 (49%)/28 (43%)/5 (8%). Immunotherapy was used as systemic first‐/second‐/third‐/fourth‐line treatment in 9 (14%)/27 (42%)/26 (40%)/3 (5%) patients. Fifty‐four patients had at least one follow‐up imaging and were, therefore, available for radiological response assessment. The overall response and disease control rates were 12% and 49% respectively. Of 52 evaluable patients, four (8%) had hyperprogressive disease. Median time to progression was 5.5 (95% CI, 3.5‐7.4) months, median progression‐free survival was 4.6 (95% CI, 3.0‐6.2) months, and median overall survival was 11.0 (95% CI, 8.2‐13.8) months. Most common adverse events were infections (n = 7), rash (n = 6), pruritus (n = 3), fatigue (n = 3), diarrhoea (n = 3) and hepatitis (n = 3). Efficacy and safety results were comparable between Child‐Pugh A and B patients; however, median overall survival (OS) was shorter in Child‐Pugh B patients (16.7 vs 8.6 months; P = 0.065). There was no difference in terms of efficacy and adverse events between patients who received immunotherapy as first‐/second‐line and third‐/fourth‐line respectively. Conclusions: Programmed cell death protein‐1‐targeted immunotherapy with nivolumab or pembrolizumab showed promising efficacy and safety in patients with advanced hepatocellular carcinoma, including subjects with Child‐Pugh stage B and patients with intensive pretreatment.

Background: Hepatocellular carcinoma has a dismal prognosis due to recurrence rates of up to 70% after curative resection. Early recurrence is driven by synchronous microscopic intrahepatic metastases. The predictive value of histological parameters is discussed controversially and adjuvant therapy is not established. The aim of this study was to identify patients at high risk for early intrahepatic recurrence by expression profiling of selected micro RNAs.Methods: In 52 patients undergoing HCC resection between 2011 and 2014, liver and tumor tissue was collected during surgery. Twelve patients with incomplete data regarding HCC recurrence, secondary liver transplantation, or perioperative death were excluded, leaving 40 patients with early recurrence <12 months (R+) or without recurrence for >24 months (R-) to compare grading, T, L, V, and R status. If tissue quality permitted, micro RNAs were measured in HCC and liver tissue.Results: Ten women and 30 men (64.0 ± 10.2 years) were analyzed. R+ occurred in 29 patients 6.2 ± 4.5 months after resection. Surveillance of R- was 26.2 ± 5.2 months. High intratumoral expression of miR-135a was associated with high risk of recurrence (HR = 4.2, p = 0.024, time to recurrence 8.8 ± 2.0 vs. 24.8 ± 4.4 months in patients with low miR-135a expression). As expected, T3 status was correlated with early recurrence, while other histological parameters and expression of miR-21, miR-122, and miR-125a did not.Conclusions: We show a significant association between high expression of miR-135a and early HCC recurrence. Therefore, high intratumoral miR-135a expression might serve as a novel biomarker to identify patients urgently requiring adjuvant therapy post resection. [ABSTRACT FROM AUTHOR]

Advanced hepatocellular carcinoma (HCC) with vascular invasion and/or extrahepatic spread and preserved liver function, according to stage C of the Barcelona Clinic Liver Cancer (BCLC) classification, has a dismal prognosis. The multi-targeted tyrosine-kinase receptor inhibitor (TKI) sorafenib is the only proven active substance in systemic HCC therapy for first-line treatment. In this review, we summarize current aspects in patient selection and management of side effects, and provide an update on response evaluation during first-line sorafenib therapy. Since second-line treatment options have been improved with the successful completion of the RESORCE trial, demonstrating a survival benefit for second-line treatment with the TKI regorafenib, response monitoring during first-line therapy will be critical to deliver optimal systemic therapy in HCC. To this regard, specific side effects, in particular worsening of arterial hypertension and diarrhea, might suggest treatment response during first-line sorafenib therapy; however, clear predictive clinical markers, as well as laboratory test or serum markers, are not established. Assessment of radiologic response according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST) is helpful to identify patients who do not benefit from sorafenib treatment.

Background: Despite complete resection, disease-free survival (DFS) of patients with cholangiocarcinoma (CCA) is less than 65 % after one year and not more than 35 % after three years. For muscle invasive gallbladder carcinoma (GBCA), prognosis is even worse, with an overall survival (OS) of only 30 % after three years. Thus, evaluation of adjuvant chemotherapy in biliary tract cancer in a large randomized trial is warranted. Methods/Design: ACTICCA-1 is a randomized, multidisciplinary, multinational phase III investigator initiated trial. With respect to data obtained in the ABC-02 trial, we selected the combination of gemcitabine and cisplatin for 24 weeks as investigational treatment. Based on adjuvant trials in pancreatic cancer with comparable postoperative recovery time, inclusion of patients within a maximum interval of 16 weeks between surgery and start of chemotherapy was stipulated. Due to the different prognosis and treatment susceptibility of muscle invasive carcinoma, two separate cohorts (CCA and GBCA) were included to capture the potentially different treatment effects. Randomization is stratified for lymph node status for both cohorts and localization for CCA. The primary endpoint is DFS and secondary endpoints include OS, safety and tolerability of chemotherapy, quality of life, and patterns of disease recurrence. For CCA, adjuvant chemotherapy should increase DFS 24 months post-surgery from 40 to 55 % to be considered relevant. With a power of 80 % and a significance level of 5 %, 271 evaluable study patients have to be followed for 24-28 months to observe 166 events. For GBCA, chemotherapy should increase DFS 24 months post-surgery from 35 to 55 % to be of relevance; thus, 154 evaluable study patients have to be monitored for 24-28 months to observe 90 events. In both cohorts, randomization will be 1:1 with chemotherapy for 24 weeks and imaging every twelve weeks. In 2014, the study was initiated in Germany and in The Netherlands (funded by the Deutsche Krebshilfe, the Dutch Cancer Society, and supported by medac GmbH). Sites in Australia, Denmark, and the United Kingdom (funded by Cancer Research UK) are joining 2015. [ABSTRACT FROM AUTHOR]
