Tumor budding in gastrointestinal neoplasms Group Lugli The main aim of the GI Tissue Medicine research group concerning tumor budding in CRC is the following: to identify potential target molecules in tumor buds and develop an anti-budding therapy. The focus lies on four clinical scenarios: pT1 CRC, stage II CRC, rectal cancer (preoperative) and colorectal liver metastases. Additionally, our group is also a member of the International Budding Consortium (IBC). pT1 colorectal cancer with high grade budding (H&E staining)
Scoring of inflammatory activity in chronic inflammatory bowel disease Group Lugli Our group is currently working on the implementation of the biopsy-based IBD-DCA score to support the prognosis of disease development and the prediction of treatment success in patients with chronic inflammatory bowel disease (IBD). In parallel, in collaboration with the Institute of Pathology at St Vincent's University Hospital in Dublin, we are developing an AI algorithm to automate the scoring. Schematic overview of how information extracted from colorectal biopsies may be used to guide treatment strategy in asymptomatic patients diagnosed with inflammatory bowel disease during colon cancer screening.
Influence of neoadjuvant therapy on the immune profile of esophageal adenocarcinomas Group Lugli Immune checkpoint inhibitors are increasingly used in the adjuvant therapy of locally advanced, neoadjuvantly treated adenocarcinomas of the esophagus. Reliable predictive biomarkers are essential to identify the patient population that shows a significant response to immune checkpoint inhibitors. We are studying the transcriptome, methylome and immunohistochemical expression profile of immunomodulatory molecules in human tumor samples. The aim is to identify key molecules that may influence the response to therapy. In addition, the impact of neoadjuvant therapy on these immunomodulatory molecules will be investigated.
