| 2 | Impact of radiotherapy on the immune landscape in oesophageal adenocarcinoma显示文摘BACKGROUND In the contemporary era of cancer immunotherapy,an abundance of clinical and translational studies have reported radiotherapy(RT)and immunotherapies as a viable option for immunomodulation of many cancer subtypes,with many related clinical trials ongoing.In locally advanced disease,chemotherapy or chemoradiotherapy followed by surgical excision of the tumour remain the principal treatment strategy in oesophageal adenocarcinoma(OAC),however,the use of the host immune system to improve anti-tumour immunity is rapidly garnering increased support in the curative setting.AIM To immunophenotype OAC patients’immune checkpoint(IC)expression with and without radiation and evaluate the effects of checkpoint blockade on cell viability.METHODS In the contemporary era of cancer immunotherapy,an abundance of studies have demonstrated that combination RT and IC inhibitors(ICIs)are effective in the immunomodulation of many cancer subtypes,with many related clinical trials ongoing.Although surgical excision and elimination of tumour cells by chemotherapy or chemoradiotherapy remains the gold standard approach in OAC,the propagation of anti-tumour immune responses is rapidly garnering increased support in the curative setting.The aim of this body of work was to immunophenotype OAC patients’IC expression with and without radiation and to establish the impact of checkpoint blockade on cell viability.This study was a hybrid combination of in vitro and ex vivo models.Quantification of serum immune proteins was performed by enzyme-linked immunosorbent assay.Flow cytometry staining was performed to evaluate IC expression for in vitro OAC cell lines and ex vivo OAC biopsies.Cell viability in the presence of radiation with and without IC blockade was assessed by a cell counting kit-8 assay.RESULTS We identified that conventional dosing and hypofractionated approaches resulted in increased IC expression(PD-1,PD-L1,TIM3,TIGIT)in vitro and ex vivo in OAC.There were two distinct subcohorts with one demonstrating significant upregulation of ICs and the contrary in the other cohort.Increasing IC expression post RT was associated with a more aggressive tumour phenotype and adverse features of tumour biology.The use of anti-PD-1 and anti-PD-L1 immunotherapies in combination with radiation resulted in a significant and synergistic reduction in viability of both radiosensitive and radioresistant OAC cells in vitro.Interleukin-21(IL-21)and IL-31 significantly increased,with a concomitant reduction in IL-23 as a consequence of 4 Gray radiation.Similarly,radiation induced an anti-angiogenic tumour milieu with reduced expression of vascular endothelial growth factor-A,basic fibroblast growth factor,Flt-1 and placental growth factor.CONCLUSION The findings of the current study demonstrate synergistic potential for the use of ICIs and ionising radiation to potentiate established anti-tumour responses in the neoadjuvant setting and is of particular interest in those with advanced disease,adverse features of tumour biology and poor treatment responses to conventional therapies. | Noel E Donlon Maria Davern Fiona O'Connell Andrew Sheppard Aisling Heeran Anshul Bhardwaj Christine Butler Ravi Narayanasamy Claire Donohoe James J Phelan Niamh Lynam-Lennon Margaret R Dunne Stephen Maher Jacintha O'Sullivan John V Reynolds Joanne Lysaght | 2022 | World Journal of Gastroenterology2022,28,21: | 1 |

| 4 | Potential of damage associated molecular patterns in synergising radiation and the immune response in oesophageal cancer显示文摘BACKGROUND There is an intimate crosstalk between cancer formation,dissemination,treatment response and the host immune system,with inducing tumour cell death the ultimate therapeutic goal for most anti-cancer treatments.However,inducing a purposeful synergistic response between conventional therapies and the immune system remains evasive.The release of damage associated molecular patterns(DAMPs)is indicative of immunogenic cell death and propagation of established immune responses.However,there is a gap in the literature regarding the importance of DAMP expression in oesophageal adenocarcinoma(OAC)or by immune cells themselves.AIM To investigate the effects of conventional therapies on DAMP expression and to determine whether OAC is an immunogenic cancer.METHODS We investigated the levels of immunogenic cell death-associated DAMPs,calreticulin(CRT)and HMGB1 using an OAC isogenic model of radioresistance.DAMP expression was also assessed directly using ex vivo cancer patient T cells(n=10)and within tumour biopsies(n=9)both pre and post-treatment with clinically relevant chemo(radio)therapeutics.RESULTS Hypoxia in combination with nutrient deprivation significantly reduces DAMP expression by OAC cells in vitro.Significantly increased frequencies of T cell DAMP expression in OAC patients were observed following chemo-(radio)therapy,which was significantly higher in tumour tissue compared with peripheral blood.Patients with high expression of HMGB1 had a significantly better tumour regression grade(TRG 1-2)compared to low expressors.CONCLUSION In conclusion,OAC expresses an immunogenic phenotype with two distinct subgroups of high and low DAMP expressors,which correlated with tumour regression grade and lymphatic invasion.It also identifies DAMPs namely CRT and HMGB1 as potential promising biomarkers in predicting good pathological responses to conventional chemo(radio)therapies currently used in the multimodal management of locally advanced disease. | Noel E Donlon Maria Davern Andrew Sheppard Fiona O'Connell Brendan Moran Timothy S Nugent Aisling Heeran James J Phelan Anshul Bhardwaj Christine Butler Narayanasamy Ravi Claire L Donohoe Niamh Lynam-Lennon Stephen Maher John V Reynolds Joanne Lysaght | 2023 | World Journal of Gastrointestinal Oncology2023,15,8: | 0 |
