Background: Precision oncology is gaining momentum in managing patients with gastrointestinal cancers. This study examines the implementation of personalized medicine technologies in upper gastrointestinal (UGI) oncology across European academic centers. Material and methods: Forty-five oncology specialists from 41 European institutions completed a survey designed by the Personalized Medicine Task Force of the European Organization of Research and Treatment of Cancer (EORTC) Gastrointestinal Tract Cancer Working Group, providing insights into molecular testing, timing, availability of targeted therapies, funding sources, and utilization of molecular tumor boards (MTBs) for patients with UGI cancers. Frequencies and percentages were calculated. Results: Routine testing for human epidermal growth factor receptor 2 (HER2, 100%), programmed death-ligand 1 (PD-L1, 89%), and DNA mismatch repair (MMR, 91%) is implemented in most centers. Comprehensive gene panels on tumor tissue are frequently utilized, especially in biliary tract cancer, with almost all centers incorporating them into routine practice. Blood-based sequencing is increasingly employed, and half of centers carry out comprehensive gene panels for circulating tumor DNA analyses. MTBs are regularly held in 76% of centers, predominantly utilizing ESMO Scale for Clinical Actionability of molecular Targets (ESCAT)-based recommendations for tissue molecular alterations. The translation of genomic information into prescribed treatments remains limited, however, with the majority of centers reporting ∼25% of molecularly stratified treatment decisions following comprehensive genetic testing. Conclusion: This survey provides important insights into current personalized medicine practice in European academic clinical centers for UGI oncology. Despite widespread adoption of molecular testing and implementation of MTBs, further efforts are needed to optimize the integration of personalized medicine into clinical practice.

Abstract Background This study evaluated the impact of time to surgery (TTS) on overall survival (OS), disease free survival (DFS) and postoperative complication rate in patients with upfront resected pancreatic adenocarcinoma (PA). Methods We retrospectively included patients who underwent upfront surgery for PA between January 1, 2004 and December 31, 2014 from four French centers. TTS was defined as the number of days between the date of the first consultation in specialist care and the date of surgery. DFS for a 14-day TTS was the primary endpoint. We also analyzed survival depending on different delay cut-offs (7, 14, 28, 60 and 75 days). Results A total of 168 patients were included. 59 patients (35%) underwent an upfront surgery within 14 days. Patients in the higher delay group (> 14 days) had significantly more vein resections and endoscopic biliary drainage. Adjusted OS (p = 0.44), DFS (p = 0.99), fistulas (p = 0.41), hemorrhage (p = 0.59) and severe post-operative complications (p = 0.82) were not different according to TTS (> 14 days). Other delay cut-offs had no impact on OS or DFS. Discussion TTS seems to have no impact on OS, DFS and 90-day postoperative morbidity.

Pachydermoperiostosis (PDP) is the primary form of hypertrophic osteoarthropathy. It is a very rare disease consisting of pachydermia, digital clubbing and radiologic periostosis. Various digestive symptoms in PDP are seen in 11–49% of patients and juvenile polyps may be found at gastric endoscopy. We report here the history of a patient with PDP who was referred for assessment of severe anemia. Endoscopy of the upper digestive tract showed multiple polyps of the stomach with two huge lesions exhibiting foci of high-grade dysplasia. This observation suggests that PDP can be considered as a precancerous condition of the stomach and systematic screening using endoscopy should be considered in these patients.

Introduction: Molecular profiling has become essential in the management of patients with biliary tract cancer (BTC). The aim of this study was to evaluate the practices of French genetics platforms in the management of BTCs., Methods: A survey was developed by a multidisciplinary group and distributed to each of the 28 French genetics platforms over a one-month period., Results: Twenty-one platforms answered the survey (75%). A majority (62%) had performed more than 50 analyses for BTCs over the last two years, with an average turnaround time for results evaluated between 11 and 15 days for 62% of them. Three quarters (76%) of the platforms performed both DNA and RNA analysis, while a quarter (24%) performed RNA analysis only. A commercial panel was used by 50% of platforms for DNA analysis, and 80% for RNA. Panels included between 10 and 50 genes for 76% of platforms. All responding platforms systematically tested for IDH1 mutations, FGFR2 fusions and BRAF mutations. A majority systematically tested for HER2 amplification, MSI status and TP53 mutation (88%, 81% and 69% respectively)., Discussion: This national survey of French genetics platforms shows good performance and compliance with recommendations for molecular analysis. However, many medical, financial and organizational obstacles remain upstream of these platforms., (Copyright © 2024 Société Française du Cancer. Published by Elsevier Masson SAS.

Intrahepatic cholangiocarcinoma (iCCA) is the second most common malignant primary liver cancer. iCCA may develop on an underlying chronic liver disease and its incidence is growing in relation with the epidemics of obesity and metabolic diseases. In contrast, perihilar cholangiocarcinoma (pCCA) may follow a history of chronic inflammatory diseases of the biliary tract. The initial management of CCAs is often complex and requires multidisciplinary expertise. The French Association for the Study of the Liver wished to organize guidelines in order to summarize the best evidence available about several key points in iCCA and pCCA. These guidelines have been elaborated based on the level of evidence available in the literature and each recommendation has been analysed, discussed and voted by the panel of experts. They describe the epidemiology of CCA as well as how patients with iCCA or pCCA should be managed from diagnosis to treatment. The most recent developments of personalized medicine and use of targeted therapies are also highlighted., (© 2024 The Authors. Liver International published by John Wiley & Sons Ltd.)

Background: Management of ampullary tumors (AT) is challenging because of a low level of scientific evidence. This document is a summary of the French intergroup guidelines regarding the management of AT, either adenoma (AA) or carcinoma (AC), published in July 2023, available on the website of the French Society of Gastroenterology (SNFGE) (www.tncd.org)., Methods: A collaborative work was conducted under the auspices of French medical, endoscopic, oncological and surgical societies involved in the management of AT. Recommendations are based on recent literature review and expert opinions and graded in three categories (A, B, C), according to quality of evidence., Results: Accurate diagnosis of AT requires at least duodenoscopy and EUS. All patients should be discussed in multidisciplinary tumor board before treatment. Surveillance may only be proposed for small AA in familial adenomatous polyposis. For AA, endoscopic papillectomy is the preferred option only if R0 resection can be achieved. When not possible, surgical papillectomy should be considered. For AC beyond pT1a N0, pancreaticoduodenectomy is the procedure of choice. Adjuvant monochemotherapy (gemcitabine, 5FU) may be proposed. For aggressive tumors (pT3/T4, pN+, R1, poorly differentiated AC, pancreatobiliary differentiation) with high risk of recurrence, 6 months polychemotherapy (CAPOX/FOLFOX for the intestinal subtype and mFOLFIRINOX for the pancreatobiliary or the mixed subtype) may be a valid alternative. Clinical and radiological follow up is recommended for 5 years., Conclusions: These guidelines help to homogenize and highlight unmet needs in the management of AA and AC. Each individual case should be discussed by a multidisciplinary team., Competing Interests: Conflict of interest VH: AAA, Amgen, Esteve, Ipsen, Deciphera, Merck, Pierre Fabre, Servier AT: personal fees from Servier, Viatris, Incyte Bioscience, BMS, Merck and grants from AstraZeneca and MSD outside the submitted work MC: Medtronic, Boston Scientific, Cook Medical, AMBU CN: Honoraria / consulting: Amgen, AstraZeneca, Baxter, Bristol-Myers Squibb, Fresenius Kabi, Incyte Biosciences, Merck, MSD, Mundipharma, Novartis, Nutricia, OSE Immunotherapeutics, Pierre Fabre, Roche, Sanofi, Servier, Viatris.

Purpose: Treatment of retroperitoneal lymph node metastases (RPN) from colon cancer (CC) is a therapeutic challenge. Available evidence supporting a curative approach is weak and uncertainties remain concerning the extent of the dissection, the optimal timing for surgery, and the role of adjuvant radiotherapy. We report the outcomes of a curative intent strategy in a recent monocentric series of patients., Methods: We did a retrospective review of all curative intent surgical treatment of RPN from CC performed consecutively in a French university hospital from June 2015 to April 2021. Demographics, clinicopathological, and molecular characteristics were evaluated. We describe recurrence-free and overall survival and factors related to recurrence., Results: Records from 18 patients were reviewed. The median age was 69 years. Most of the patients were male (55%), ASA 1-2 (94%), had a left-sided primary colon cancer (73%), and had metachronous RPN (62%). Thirteen patients (72%) experienced recurrence. Recurrence was often limited to RPN (27%) or liver (22%). Four patients underwent a second surgery for RPN recurrence. Median disease-free and overall survival were 22 months and 50 months after RPN surgery. We did not find any factor associated with recurrence. Short-term recurrence (< 6 months) was associated with shorter overall survival (0.031)., Conclusion: The current results suggest that RPN resection is feasible and associated with long survival in selected patients. Further studies evaluating the benefit of curative strategies including radical surgery for patients with potentially resectable RPN are warranted., (© 2024.

Background & Aims: Accumulating data has shown the rising incidence and poor prognosis of early-onset gastrointestinal cancers, but few data exist on biliary tract cancers (BTC). We aimed to analyse the clinico-pathological, molecular, therapeutic characteristics and prognosis of patients with early onset BTC (EOBTC, age ≤50 years at diagnosis), versus olders., Methods: We analysed patients diagnosed with intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gallbladder adenocarcinoma between 1 January 2003 and 30 June 2021. Baseline characteristics and treatment were described in each group and compared. Progression-free survival, overall survival and disease-free survival were estimated in each group using the Kaplan-Meier method., Results: Overall, 1256 patients were included, 188 (15%) with EOBTC. Patients with EOBTC demonstrated fewer comorbidities (63.5% vs. 84.5%, p < .0001), higher tumour stage (cT3-4: 50.0% vs. 32.3%, p = .0162), bilobar liver involvement (47.8% vs. 32.1%, p = .0002), and metastatic disease (67.6% vs. 57.5%, p = .0097) compared to older. Patients with EOBTC received second-line therapy more frequently (89.5% vs. 81.0% non-EOBTC, p = .0224). For unresectable patients with BTC, median overall survival was 17.0 vs. 16.2 months (p = .0876), and median progression-free survival was 5.8 vs. 6.0 months (p = .8293), in EOBTC vs. older. In advanced stages, fewer actionable alterations were found in EOBTC (e.g., IDH1 mutations [7.8% vs. 16.6%]; FGFR2-fusion [11.7% vs. 8.9%]; p = .029)., Conclusions: Patients with EOBTC have a more advanced disease at diagnosis, are treated more heavily at an advanced stage but show similar survival. A distinctive molecular profile enriched for FGRF2 fusions was found., (© 2024 The Authors. Liver International published by John Wiley & Sons Ltd.)

Background and Aims: To gather real-life data on biliary tract cancer (BTC) in France, an ambispective ACABi GERCOR Pronobil cohort was initiated. This nested study, Amber, utilized data from this cohort to document clinical practices in this setting., Methods: Inclusion criteria encompassed patients with locally advanced/metastatic BTC managed between 2019 and 2021 in nine French referral hospitals. Objectives included describing demographic and clinical data, treatments outcomes (safety and efficacy), and overall survival., Results: Of the 138 patients (median age 65 years, a balanced sex ratio) included, most displayed ECOG 0-1 (83 %), at least one comorbidity (79 %), and had intrahepatic (56 %) and metastatic (82 %) BTC. Among surgically-resected patients, 60 % received adjuvant chemotherapy, mainly capecitabine (67 %). CisGem, the primary first-line palliative chemotherapy (69 %), showed a 23 % objective response rate, a median progression-free survival of 5.3 months, and a median overall survival of 13.4 months. Second-, third-, and fourth-line were given to 75 % (FOLFOX: 35 %, targeted therapy: 14 %), 32 %, and 13 % of patients. In total, 67 % of patients had a molecular profile (IDH1 mutations and FGFR2 fusions: accounting for 21 % each in intrahepatic cholangiocarcinoma)., Conclusion: BTC patients were predominantly treated according to international recommendations. The obtained demographic, tumor, and molecular data were consistent with existing literature., Competing Interests: Conflict of interest MD: reports receiving research funding from AstraZeneca.

Introduction: This document is a summary of the French intergroup guidelines of the management of biliary tract cancers (BTC) (intrahepatic, perihilar and distal cholangiocarcinomas, and gallbladder carcinomas) published in September 2023, available on the website of the French Society of Gastroenterology (SNFGE) (www.tncd.org)., Methods: This collaborative work was conducted under the auspices of French medical and surgical societies involved in the management of BTC. Recommendations were graded in three categories (A, B and C) according to the level of scientific evidence until August 2023., Results: BTC diagnosis and staging is mainly based on enhanced computed tomography, magnetic resonance imaging and (endoscopic) ultrasound-guided biopsy. Treatment strategy depends on BTC subtype and disease stage. Surgery followed by adjuvant capecitabine is recommended for localised disease. No neoadjuvant treatment is validated to date. Cisplatin-gemcitabine chemotherapy combined to the anti-PD-L1 inhibitor durvalumab is the first-line standard of care for advanced disease. Early systematic tumour molecular profiling is recommended to screen for actionable alterations (IDH1 mutations, FGFR2 rearrangements, HER2 amplification, BRAF V600E mutation, MSI/dMMR status, etc.) and guide subsequent lines of treatment. In the absence of actionable alterations, FOLFOX chemotherapy is the only second-line standard-of-care. No third-line chemotherapy standard is validated to date., Conclusion: These guidelines are intended to provide a personalised therapeutic strategy for daily clinical practice. Each individual BTC case should be discussed by a multidisciplinary team., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Gael Roth declares consulting or advisory role or invitation as a speaker for Servier, AstraZeneca, Bristol-Myers Squibb, MSD, Amgen, Ipsen, Accord Healthcare, Pierre Fabre, Incyte, Netris Pharma and Alpha Tau, as well as travel accommodations, or expenses from Servier, AstraZeneca, Bristol Myers Squibb, MSD, Roche, Amgen, Viatris, Pierre Fabre and Ipsen.

The maintenance and optimization of functional capacities before, during, and after treatment are major challenges for frailty persons as cancer's patients. It is now known that physical activity in prehabilitation plays a crucial role in limiting, among other things, post-operative complications. The benefits have already been demonstrated in various studies, including a decrease in hospitalization duration, an increase in cardiorespiratory endurance, improvement in quality of life, and better fatigue management. It is observed that patients who undergo prehabilitation are those who recover their preoperative capacities the fastest. However, it is estimated that only one-third of patients with access to prehabilitation improve their physical capacities., (Copyright © 2024 Elsevier Masson SAS. All rights reserved.)

Purpose: GEMPAX was an open-label, randomized phase III clinical trial designed to assess the efficacy and tolerability of gemcitabine plus paclitaxel versus gemcitabine alone as second-line treatment for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) who previously received 5-fluorouracil, oxaliplatin, and irinotecan., Methods: Patients with histologically or cytologically confirmed mPDAC were randomly assigned (2:1) to receive GEMPAX (paclitaxel 80 mg/m 2 + gemcitabine 1,000 mg/m 2 ; IV; once at day (D) 1, D8, and D15/arm A) or gemcitabine (arm B) alone once at D1, D8, and D15 every 28 days until progression, toxicity, or patient's decision. The primary end point was overall survival (OS). Secondary end points included progression-free survival (PFS), objective response rate (ORR), quality of life, and safety., Results: Overall, 211 patients (median age, 64 [30-86] years; 62% male) were included. After a median study follow-up for alive patients of 13.4 versus 13.8 months in arm A versus arm B, the median OS (95% CI) was 6.4 (5.2 to 7.4) versus 5.9 months (4.6 to 6.9; hazard ratio [HR], 0.87 [0.63 to 1.20]; P = 0.4095), the median PFS was 3.1 (2.2 to 4.3) versus 2.0 months (1.9 to 2.3; HR, 0.64 [0.47 to 0.89]; P = 0.0067), and the ORR was 17.1% (11.3 to 24.4) versus 4.2% (0.9 to 11.9; P = 0.008) in arm A versus arm B, respectively. Overall, 16.7% of patients in arm A and 2.9% in arm B discontinued their treatment because of adverse events (AEs). One grade 5 AE associated with both gemcitabine and paclitaxel was reported in arm A (acute respiratory distress), and 58.0% versus 27.1% of patients experienced grade ≥3 treatment-related AEs in arm A versus arm B, among which 15.2% versus 4.3% had anemia, 15.9% versus 15.7% had neutropenia, 19.6% versus 4.3% had thrombocytopenia, 10.1% versus 2.9% had asthenia and 12.3% versus 0.0% had neuropathy., Conclusion: While GEMPAX did not meet the primary end point of OS versus gemcitabine alone in patients with mPDAC in the second-line setting, both PFS and ORR were significantly improved.

Background: Pemigatinib is approved for patients with pretreated, locally advanced or metastatic CCA harboring FGFR2 rearrangements or fusions. We aim to assess the effectiveness and safety of pemigatinib in real-world setting., Material and Methods: A joint analysis of two multicentre observational retrospective cohort studies independently conducted in France and Italy was performed. All consecutive FGFR2-positive patients affected by CCA and treated with pemigatinib as second- or further line of systemic treatment in clinical practice, within or outside the European Expanded Access Program, were included., Results: Between July 2020 and September 2022, 72 patients were treated with pemigatinib in 14 Italian and 25 French Centres. Patients had a median age of 57 years, 76% were female, 81% had ECOG-PS 0-1, 99% had intrahepatic CCA, 74% had ≥ 2 metastatic sites, 67% had metastatic disease at diagnosis, while 38.8% received ≥ 2 previous lines of systemic treatment. At data cut-off analysis (April 2023), ORR and DCR were 45.8% and 84.7%, respectively. Median DoR was 7 months (IQR: 5.8-9.3). Over a median follow-up time of 19.5 months, median PFS and 1-year PFS rate were 8.7 months and 32.8%. Median OS and 1-year OS rate were 17.1 months and 60.6%. Fatigue (69.4%), ocular toxicity (68%), nail toxicities (61.1%), dermatologic toxicity (41.6%) hyperphosphataemia (55.6%), stomatitis (48.6%), and diarrhea (36.1%) were the most frequent, mainly G1-G2 AEs. Overall incidence of G3 AEs was 22.2%, while no patient experienced G4 AE. Dose reduction and temporary discontinuation were needed in 33.3% and 40.3% of cases, with 1 permanent discontinuation due to AEs., Conclusions: These results confirm the effectiveness and safety of pemigatinib in a real-world setting., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: High tumor mutational burden (TMB) was reported to predict the efficacy of immune checkpoint inhibitors (ICIs). Pembrolizumab, an anti-PD-1, received FDA-approval for the treatment of unresectable/metastatic tumors with high TMB as determined by the FoundationOne®CDx test. It remains to be determined how TMB can also be calculated using other tests., Results: FFPE/frozen tumor samples from various origins were sequenced in the frame of the Institut Curie (IC) Molecular Tumor Board using an in-house next-generation sequencing (NGS) panel. A TMB calculation method was developed at IC (IC algorithm) and compared to the FoundationOne® (FO) algorithm. Using IC algorithm, an optimal 10% variant allele frequency (VAF) cut-off was established for TMB evaluation on FFPE samples, compared to 5% on frozen samples. The median TMB score for MSS/POLE WT tumors was 8.8 mut/Mb versus 45 mut/Mb for MSI/POLE-mutated tumors. When focusing on MSS/POLE WT tumor samples, the highest median TMB scores were observed in lymphoma, lung, endometrial, and cervical cancers. After biological manual curation of these cases, 21% of them could be reclassified as MSI/POLE tumors and considered as "true TMB high." Higher TMB values were obtained using FO algorithm on FFPE samples compared to IC algorithm (40 mut/Mb [10-3927] versus 8.2 mut/Mb [2.5-897], p < 0.001)., Conclusions: We herein propose a TMB calculation method and a bioinformatics tool that is customizable to different NGS panels and sample types. We were not able to retrieve TMB values from FO algorithm using our own algorithm and NGS panel., (© 2024. The Author(s).)

The management of anal squamous cell carcinoma (ASCC) has yet to experience the transformative impact of precision medicine. Conducting genomic analyses may uncover novel prognostic biomarkers and offer potential directions for the development of targeted therapies. To that end, we assessed the prognostic and theragnostic implications of pathogenic variants identified in 571 cancer-related genes from surgical samples collected from a homogeneous, multicentric French cohort of 158 ASCC patients who underwent abdominoperineal resection treatment. Alterations in PI3K/AKT/mTOR, chromatin remodeling, and Notch pathways were frequent in HPV-positive tumors, while HPV-negative tumors often harbored variants in cell cycle regulation and genome integrity maintenance genes (e.g., frequent TP53 and TERT promoter mutations). In patients with HPV-positive tumors, KMT2C and PIK3CA exon 9/20 pathogenic variants were associated with worse overall survival in multivariate analysis (Hazard ratio (HR) KMT2C  = 2.54, 95%CI = [1.25,5.17], P value = .010; HR PIK3CA  = 2.43, 95%CI = [1.3,4.56], P value = .006). Alterations with theragnostic value in another cancer type was detected in 43% of patients. These results suggest that PIK3CA and KMT2C pathogenic variants are independent prognostic factors in patients with ASCC with HPV-positive tumors treated by abdominoperineal resection. And, importantly, the high prevalence of alterations bearing potential theragnostic value strongly supports the use of genomic profiling to allow patient enrollment in precision medicine clinical trials., (© 2023 UICC.)

Backgound and Aims: In advanced, liver-only intrahepatic cholangiocarcinoma (iCCA), selective internal radiation therapy (SIRT) has been suggested as promising in nonrandomized studies. We aimed to compare data from patients with advanced, liver-only iCCA treated in the first line in clinical trials with either chemotherapy alone or the combination with SIRT., Approach and Results: We collected individual patients' data from the ABC-01, ABC-02, ABC-03, BINGO, AMEBICA, and MISPHEC prospective trials. Data from patients with liver-only iCCA treated in chemotherapy-only arms of the first 5 trials were compared with data from patients treated with SIRT and chemotherapy in MISPHEC. Emulated target trial paradigm and Inverse Probability of Treatment Weighting (IPTW methods) using the propensity score were used to minimize biases. We compared 41 patients treated with the combination with 73 patients treated with chemotherapy alone, the main analysis being in 43 patients treated with cisplatin-gemcitabine or gemcitabine-oxaliplatin. After weighting, overall survival was significantly higher in patients treated with SIRT: median 21.7 months (95% CI: 14.1; not reached) versus 15.9 months(95% CI: 9.8; 18.9), HR = 0.59 (95% CI: 0.34; 0.99), p = 0.049. Progression-free survival was significantly improved: median 14.3 months (95% CI: 7.8; not reached) versus 8.4 months (95% CI: 5.9; 12.1), HR = 0.52 (95% CI: 0.31; 0.89), p < 0.001. Results were confirmed in most sensitivity analyses., Conclusions: This analysis derived from prospective clinical trials suggests that SIRT combined with chemotherapy might improve outcomes over chemotherapy alone in patients with advanced, liver-only iCCA. Randomized controlled evidence is needed to confirm these findings., (Copyright © 2023 American Association for the Study of Liver Diseases.)

Neuregulin 1 ( NRG1 ) fusions are oncogenic drivers that have been detected in non-small-cell lung cancer (NSCLC), pancreatic ductal adenocarcinoma (PDAC) and other solid tumors. NRG1 fusions are rare, occurring in less than 1% of solid tumors. Patients with NRG1 fusion positive (NRG1+) cancer have limited therapeutic options. Zenocutuzumab is a novel, bispecific IgG1 antibody that targets both HER2 and HER3 proteins and inhibits NRG1 binding through a 'Dock & Block ® ' mechanism of action. Here, we describe the rationale and design of the phase II component of the eNRGy trial, part of the overall, open-label phase I/II, multicenter trial exploring the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and antitumor activity of zenocutuzumab in patients with NRG1+ NSCLC, PDAC or other solid tumors.

Background: The impact of adapted physical activity (APA) on health-related quality of life (HRQoL) in patients with advanced pancreatic ductal adenocarcinoma (aPDAC) is unknown. This study evaluated whether APA in addition to standard care improved HRQoL in patients who have aPDAC who are receiving first-line chemotherapy., Patients and Methods: Patients with locally advanced/metastatic PDAC and an ECOG performance status of 0 to 2 were randomized (1:1) to receive standard care (standard arm) or standard care plus a home-based 16-week APA program (APA arm). The primary objective was the effect of the APA program on 3 dimensions of the EORTC QLQ-C30: global health status, physical function, and fatigue at week 16 (W16), with a one-sided type I error of 0.017 for each dimension. The primary HRQoL analysis was performed in patients with available baseline and W16 scores for the dimensions (ie, the modified intention-to-treat population 1 [mITT1]), and secondary longitudinal HRQoL analyses using the mixed model for repeated measures (MMRM) and time until definitive deterioration (TUDD) methods were performed in the mITT1 population and in patients with baseline and at least one follow-up questionnaire (mITT2 population). A difference of ≥5 points was considered to be clinically relevant., Results: Of 326 included patients, 313 were randomized to the standard (n=157) or APA (n=156) arms. In the mITT1 population (n=172), the mean differences in global health status, physical function, and fatigue at W16 adjusted from baseline were -0.98 (SD, 23.9; P=.39), -2.08 (SD, 21.3; P=.26), and 4.16 (SD, 29.2; P=.17), respectively, showing a non-statistically significant benefit with APA. In the mITT2 population (n=259), APA was associated with statistically significant and clinically relevant improvement in 5 and 8 dimensions of the HRQoL in the longitudinal MMRM and TUDD analyses, respectively., Conclusions: APA improved several dimensions of HRQoL in patients with aPDAC receiving first-line chemotherapy and standard care.

Purpose: Treatment of pulmonary metastases (PM) from colorectal cancer (CRC) is the standard of care by several guidelines from Europe and the USA, but the validity of this strategy has been recently questioned, and the available evidence supporting this strategy is weak. We report the outcomes of a curative intent strategy in a very recent and homogenous series of patients., Methods: We did a retrospective review of all curative intent surgical or ablative treatment of PM from CRC performed consecutively in 3 French institutions from January 2015 to December 2019. Demographics, clinicopathological, and molecular characteristics were evaluated. Cox regression models were used to identify prognostic factors related to local recurrence and disease-free survival., Results: Records from 152 patients were reviewed. One-hundred thirty-five patients (88%) had surgical metastasectomy. Median age was 67 years. Most of the patients had a single lesion (66%), and 16% had synchronous PM. Eighty-one patients (53%) experienced recurrence, and the thorax was the most common site of recurrence. Median disease-free survival and overall survival were 35 months and 78 months after PM treatment. At the end of the study, only 17% of the patients died. Pulmonary tumor burden was correlated with disease-free survival in univariate analysis, but multivariate analysis did not find any prognostic factor independently associated with local recurrence or survival., Conclusion: Our finds corroborate existing recommendation for the invasive treatment of PM from CRC in selected patients., (© 2023.

Pancreatic ductal adenocarcinoma is associated with a poor prognosis and there are few treatment options. The development of immunotherapy in pancreatic ductal adenocarcinoma has been difficult, and immune checkpoint inhibitors are only effective in a very small subset of patients. Most obstacles for treatment have been related to intertumoural and intratumoural heterogeneity, the composition of tumour stroma, and crosstalk with cancer cells. Improved molecular characterisation of pancreatic ductal adenocarcinoma and a better understanding of its microenvironment have paved the way for novel immunotherapy strategies, including the identification of predictive biomarkers, the development of rational combinations to optimise effectiveness, and the targeting of new mechanisms. Future immunotherapy strategies should consider individual characteristics to move beyond the traditional immune targets and circumvent the resistance to therapies that have been developed so far., Competing Interests: Declaration of interests VC-R received grants from the Pancreatic Cancer Action Network and the Francois Wallace Monahan Fund in loving memory of Michael Insel.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers with increasing incidence. Even if progress have been made, the five-year overall survival remains lower than 10%. There is a desperate need in therapeutic improvements. In the last two decades, new in-vitro models have been developed and improved, including tridimensional-culture spheroids and organoids. However, animal studies remain mandatory in the upscaling before clinical studies. Orthotopic and syngeneic grafting is a robust model to test a drug efficiency in a tumor and its microenvironment., Methods: We described a method for orthotopic and syngeneic graft of KRAS mutated, p53 wildtype, 8305 cells in a C57BL/6J mouse model., Results: With this microsurgical method, 30 mice were grafted, 24 by a junior and six by a senior, resulting in 95,8 and 100% of (partial and total) successful tumoral implantation, respectively. Twenty mice underwent ultrasound follow-up. It was an efficient method for the tumoral growth evaluation. At day 16 after grafting, 85% of the tumors were detectable by ultrasound, and at day 22 all tumors were detected., Conclusions: The presented method appears to be a robust and reliable method for pre-clinical studies. A junior master student can provide positive results using this technique, which can be improved with training.

The European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines, shortened in 2021, are widely used for providing the most suitable nutrition support to patients with cancer. However, there is a lack of specialized guidelines for different cancer types. In 2020, members of the French medical and surgical societies involved in digestive oncology, nutrition and supportive care developed the Thésaurus National de Cancérologie Digestive (TNCD) practice guidelines which are specific nutritional and physical activity guidelines for patients with digestive cancers. These guidelines were recently updated in 2022. This review discusses the French intergroup guidelines, specifically in the context of pancreatic cancer at different stages of the disease. Pancreatic cancer is highly prevalent in Europe, with an increasing worldwide incidence over the last three decades. In France alone, about 14,000 new cases of pancreatic cancer are reported annually. More than 60% of patients with pancreatic cancer reportedly experience malnutrition and other nutritional issues which are known to have a negative impact on quality of life, treatment tolerability, general morbidity, and mortality. Given that the recommendations of TNCD guidelines correlate to other guidelines like the International Study Group on Pancreatic Surgery (ISGPS; for the perioperative setting), ESPEN and Spanish Society of Medical Oncology (SEOM) guidelines, their use can be suitably applied in other European countries. This review discusses the recommendations issued by nutrition guidelines, the challenges with effective integration of nutrition support in oncologic treatment, and the proposed algorithms on patient care pathways for pancreatic cancer management in the clinical setting., Competing Interests: Declaration of Competing Interest R.

Immune checkpoint inhibitors (ICI) have deeply changed the therapeutic management of a broad spectrum of solid tumors. Recent observations showed that obese patients receiving ICIs might have better outcomes than those with normal weight, while obesity was historically associated with a worse prognosis in cancer patients. Of note, obesity is associated with alterations in the gut microbiome profile, which interacts with immune and inflammatory pathways, both at the systemic and intratumoral levels. As the influence of the gut microbiota on the response to ICI has been repeatedly reported, a specific gut microbiome profile in obese cancer patients may be involved in their better response to ICI. This review summarizes recent data on the interactions between obesity, gut microbiota, and ICIs. In addition, we highlight possible pathophysiological mechanisms supporting the hypothesis that gut microbiota could be one of the links between obesity and poor response to ICIs., Competing Interests: Declaration of Competing Interest CN: Amgen, AstraZeneca, Baxter, Bristol-Myers Squibb, Fresenius Kabi, Incyte Biosciences, Merck, MSD, Mylan, Novartis, Nutricia, Pierre Fabre, Roche, Sanofi, Servier (consultant), Roche (research funding), AstraZeneca, Bristol-Myers Squibb, OSE Immunotherapeutics (clinical trials).

Two tumor (Classical/Basal) and stroma (Inactive/active) subtypes of Pancreatic adenocarcinoma (PDAC) with prognostic and theragnostic implications have been described. These molecular subtypes were defined by RNAseq, a costly technique sensitive to sample quality and cellularity, not used in routine practice. To allow rapid PDAC molecular subtyping and study PDAC heterogeneity, we develop PACpAInt, a multi-step deep learning model. PACpAInt is trained on a multicentric cohort (n = 202) and validated on 4 independent cohorts including biopsies (surgical cohorts n = 148; 97; 126 / biopsy cohort n = 25), all with transcriptomic data (n = 598) to predict tumor tissue, tumor cells from stroma, and their transcriptomic molecular subtypes, either at the whole slide or tile level (112 µm squares). PACpAInt correctly predicts tumor subtypes at the whole slide level on surgical and biopsies specimens and independently predicts survival. PACpAInt highlights the presence of a minor aggressive Basal contingent that negatively impacts survival in 39% of RNA-defined classical cases. Tile-level analysis ( > 6 millions) redefines PDAC microheterogeneity showing codependencies in the distribution of tumor and stroma subtypes, and demonstrates that, in addition to the Classical and Basal tumors, there are Hybrid tumors that combine the latter subtypes, and Intermediate tumors that may represent a transition state during PDAC evolution., (© 2023.

Supportive care plays a central role in the management of patients with esophagogastric cancers, at all disease stages. Malnutrition has a high prevalence in this population, reaching up to 60 % of the patients. Sarcopenia and cachexia are also common. These complications have negative impact on functional abilities, quality of life and overall survival. They impair anti-tumor treatments effectiveness and increase their toxicity. Early detection and management are needed, before reaching advanced stages, which are refractory to therapeutic interventions. Specific nutritional support is recommended, relying on different nutritional support tools (dietetic counseling, oral supplements, artificial nutrition), depending on the clinical situation. When artificial nutrition is recommended, enteral nutrition (nasogastric tube, gastrostomy or jejunostomy) should be preferred. When enteral nutrition is impossible or insufficient, parenteral nutrition could be necessary. For patients with advanced esophagogastric cancers, digestive prostheses and decompressive radiation therapy may have a symptomatic benefit on dysphagia. Adapted physical activity is also recommended at all stages of cancer care and ongoing clinical trials will help to specify its modalities and to optimize its place in the therapeutic strategy. Finally, psychosocial support could be useful. A combined approach of these different interventions on the nutritional, physical and psychological aspects is beneficial for patients with esophagogastric cancers. This multimodal and multidisciplinary approach applies to both the early stages of the disease, with prehabilitation and/or rehabilitation to reduce perioperative morbidity and mortality and the advanced stages, with a benefit on survival and quality of life, in parallel with anti-tumor treatments., (Copyright © 2022 Société Française du Cancer.

Background: Data on the role of the microbiota in cancer have accumulated in recent years, with particular interest in intratumoral bacteria. Previous results have shown that the composition of intratumoral microbiome is different depending on the type of primary tumour and that bacteria from the primary tumour could migrate to metastatic sites., Methods: Seventy-nine patients with breast, lung, or colorectal cancer and available biopsy samples from lymph node, lung, or liver site, treated in the SHIVA01 trial were analysed. We performed bacterial 16S rRNA gene sequencing on these samples to characterise the intratumoral microbiome. We assessed the association between microbiome composition, clinicopathological characteristics, and outcomes., Results: Microbial richness (Chao1 index), evenness (Shannon index) and beta-diversity (Bray Curtis distance) were associated with biopsy site (p = 0.0001, p = 0.03 and p < 0.0001, respectively) but not with primary tumour type (p = 0.52, p = 0.54 and p = 0.82, respectively). Furthermore, microbial richness was inversely associated with tumour-infiltrating lymphocytes (TILs, p = 0.02), and PD-L1 expression on immune cells (p = 0.03), or assessed by Tumor Proportion Score (TPS, p = 0.02) or Combined Positive Score (CPS, p = 0.04). Beta-diversity was also associated with these parameters (p < 0.05). Patients with lower intratumoral microbiome richness had shorter overall survival (p = 0.03) and progression-free survival (p = 0.02) in multivariate analysis., Conclusion: Biopsy site, rather than primary tumour type, was strongly associated with microbiome diversity. Immune histopathological parameters such as PD-L1 expression and TILs were significantly associated with alpha and beta-diversity supporting the cancer-microbiome-immune axis hypothesis., (Copyright © 2023 Elsevier Ltd.

Purpose: Cholangiocarcinoma (CCA) is usually diagnosed at advanced stages, with limited therapeutic options. Preclinical models focused on unresectable metastatic CCA are necessary to develop rational treatments. Pathogenic mutations in IDH1/2, ARID1A/B, BAP1, and BRCA1/2 have been identified in 30%-50% of patients with CCA. Several types of tumor cells harboring these mutations exhibit homologous recombination deficiency (HRD) phenotype with enhanced sensitivity to PARP inhibitors (PARPi). However, PARPi treatment has not yet been tested for effectiveness in patient-derived models of advanced CCA., Experimental Design: We have established a collection of patient-derived xenografts from patients with unresectable metastatic CCA (CCA&#95;PDX). The CCA&#95;PDXs were characterized at both histopathologic and genomic levels. We optimized a protocol to generate CCA tumoroids from CCA&#95;PDXs. We tested the effects of PARPis in both CCA tumoroids and CCA&#95;PDXs. Finally, we used the RAD51 assay to evaluate the HRD status of CCA tissues., Results: This collection of CCA&#95;PDXs recapitulates the histopathologic and molecular features of their original tumors. PARPi treatments inhibited the growth of CCA tumoroids and CCA&#95;PDXs with pathogenic mutations of BRCA2, but not those with mutations of IDH1, ARID1A, or BAP1. In line with these findings, only CCA&#95;PDX and CCA patient biopsy samples with mutations of BRCA2 showed RAD51 scores compatible with HRD., Conclusions: Our results suggest that patients with advanced CCA with pathogenic mutations of BRCA2, but not those with mutations of IDH1, ARID1A, or BAP1, are likely to benefit from PARPi therapy. This collection of CCA&#95;PDXs provides new opportunities for evaluating drug response and prioritizing clinical trials., (©2022 The Authors; Published by the American Association for Cancer Research.)

Biliary tract cancers (BTCs) are a heterogeneous group of tumors that are rare in Western countries and have a poor prognosis. Three subgroups are defined by their anatomical location (intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma and gallbladder carcinoma) and exhibit distinct clinical, molecular, and epidemiologic characteristics. Most patients are diagnosed at an advanced disease stage and are not eligible for curative-intent resection. In addition to first- and second-line chemotherapies (CisGem and FOLFOX, respectively), biologic therapies are now available that target specific genomic alterations identified in BTC. To date, targets include alterations in the genes for isocitrate dehydrogenase (IDH) 1, fibroblast growth factor receptor (FGFR) 2, v-raf murine sarcoma viral oncogene homolog B1 (BRAF), human epidermal growth factor receptor 2 (HER2 or ERRB2), and neurotrophic tyrosine receptor kinase (NTRK), and for those leading to DNA mismatch repair deficiency. Therapies targeting these genomic alterations have demonstrated clinical benefit for patients with BTC. Despite these therapeutic advancements, genomic diagnostic modalities are not widely used in France, owing to a lack of clinician awareness, local availability of routine genomic testing, and difficulties in obtaining health insurance reimbursement. The addition of durvalumab, a monoclonal antibody targeting the immune checkpoint programmed cell death ligand-1, to CisGem in the first-line treatment of advanced BTC has shown an overall survival benefit in the TOPAZ-1 trial. Given the high mortality rates associated with BTC and the life-prolonging therapeutic options now available, it is hoped that the data presented here will support updates to the clinical management of BTC in France., (© 2023.

Cholangiocarcinoma is a deadly cancer comprising very heterogenous subtypes with a limited therapeutic arsenal in all comers. However, recent significant advances were made with immunotherapy in the first-line treatment of advanced cholangiocarcinoma, with the addition of durvalumab to cisplatin-gemcitabine chemotherapy showing a survival benefit. In the second line setting, only FOLFOX (5FU/folinic acid-oxaliplatin) is validated by a phase 3 trial, yet with a very modest benefit on survival; new options using 5FU with nanoliposomal-irinotecan may emerge in the next few years. The advent of molecular profiling in advanced cholangiocarcinoma in the last decade revealed frequent targetable alterations such as IDH1 mutations, FGFR2 fusions or rearrangements, HER2 amplification, BRAF V600E mutation and others. This strategy opened the way to personalised medicine for patients which are still fit after first-line treatment and the use of targeted inhibitors in first line constitutes a huge challenge with many ongoing trials to improve patients' care. This review exposes the recent clinical trial findings in non-molecularly selected advanced cholangiocarcinoma, offers a focus on how systematic molecular screening should be structured to allow patients to access to personalised medicine, and details which are the therapeutic options accessible in case of actionable alteration., Competing Interests: Conflict of interest statement Gael S Roth declares consulting or advisory role for Servier, AstraZeneca, Bristol Myers Squibb, MSD, Servier, Amgen, Ipsen, Viatris, Accord Healthcare, Sanofi; travel, accommodations or expenses from Servier, AstraZeneca, Bristol Myers Squibb, MSD, Roche, Amgen, Ipsen.

After failure of first line FOLFOX-bevacizumab for metastatic colorectal cancer (mCRC), adding either bevacizumab or aflibercept to second-line FOLFIRI increases survival compared to FOLFIRI alone. In this French retrospective multicentre cohort, we included patients with a mCRC treated with either FOLFIRI-aflibercept or FOLFIRI-bevacizumab. The primary endpoint was overall survival (OS), and secondary endpoints were progression-free survival (PFS), disease control rate (DCR: CR + PR + SD) and safety. We included 681 patients from 36 centers, 326 and 355 in the aflibercept and bevacizumab groups, respectively. Median age was 64.2 years and 45.2% of patients were men. Most patients had RAS-mutated tumors (80.8%) and synchronous metastases (85.7%). After a median follow up of 31.2 months, median OS was 13.0 months (95% CI: 11.3-14.7) and 10.4 months (95% CI: 8.8-11.4) in the bevacizumab and aflibercept groups, respectively (P &lt; .0001). Median PFS was 6.0 months (95% CI: 5.4-6.5) and 5.1 months (95% CI: 4.3-5.6) (P &lt; .0001). After adjustment on age, PS, PFS of first line, primary tumor resection, metastasis location and RAS/BRAF status, bevacizumab was still associated with better OS (HR: 0.71, 95% CI: 0.59-0.86, P = .0003). FOLFIRI-bevacizumab combination was associated with longer OS and PFS, and a better tolerability, as compared to FOLFIRI-aflibercept after progression on FOLFOX-bevacizumab., (© 2022 UICC.)

Background: Overall response rate (ORR) and progression-free survival (PFS) are commonly used as endpoints for phase II trials. However, the ultimate goal is to bring survival benefit for the patients. We aimed to assess the correlation between ORR, median PFS and overall survival (OS) using aggregated data from a systematic review of second-line systemic therapies in advanced biliary tract cancer (BTC) patients., Methods: Clinical trials were identified using Medline database. Studies only enrolling patients with gallbladder cancer were not included. Searches were last updated on April 2020. Eligible studies reported OS, PFS and/or ORR data for BTC patients receiving second-line systemic chemotherapy. Pearson weighted correlation was estimated between OS and ORR and between median OS and PFS., Results: Seventeen studies (N = 912 patients) were selected. There was a strong correlation between median OS/ORR in the overall analysis (r = 0.85; P < 0.0001), both for trials with chemotherapy (r = 0.90; P=0.0152) and targeted therapy (r = 0.84; P = 0.0006). In contrast, the correlation between median OS/PFS, albeit significant in the overall analysis (r = 0.80; P < 0.0001), remained significant only for targeted therapies in the sensitivity analysis (r = 0.83; P = 0.0009)., Conclusions: ORR seems to be a more interesting intermediate endpoint in BTC in second line for both chemotherapy and targeted therapies, while PFS may be relevant only for targeted therapy trials. Further well-designed studies for surrogacy evaluation should be performed to confirm this observation., Competing Interests: Declaration of Competing Interest CN: honoraria/consultancy: AAA/Novartis, Amgen, AstraZeneca, Baxter, Bristol-Myers Squibb, Fresenius Kabi, Incyte Biosciences, Merck, MSD, Mylan/Viatris, Nutricia, Pierre Fabre, Roche, Sanofi, Servier.
