Dissecting the evolutionary trajectory of resistance and residual disease in EGFR-mutant lung cancer on the single-cell level

 

One Fellow...Two Questions

Sebastian, what was your motivation of becoming an EKFS fellow?

Individual encounters at the clinics and the commitment of patient advocacy groups, such as the ROS1onders, are driving my motivation to improve the prognosis of cancer patients. I am convinced that the integration of pre‐clinical and clinical discovery is essential to foster advances in cancer treatment. The rapid translation of pre‐clinical findings into patient care and vice versa, is only possible through a tight interaction between clinics and clinical and pre‐clinical research. As a clinician and researcher, I aim to fulfil these requirements.

The EKFS postgraduate fellowship program allows me to join the excellent local pre‐clinical structures and to add clinical incentives to the field of lung cancer research.

 

Where lie your clinical and scientific interests?

Since my MD student fellowship at the sarcoma research group of Wolfgang Hartmann (Institute of Pathology, University Hospital of Bonn), I have been fascinated by cancer biology and treatment and quickly discovered, that I wanted to become medical oncologist.

As a clinician scientist at the Lung Cancer Group Cologne, I learned that the biggest medical need was the treatment of acquired resistance to targeted treatments and the understanding of the driving mechanisms. Inspired by the fruitful interaction with the Institute of Pathology and other research groups, I decided to join the genomics research group of Axel Hillmer in January 2020.

The aim of my research there, is to understand the mechanisms that drive genomic and transcriptomic heterogeneity in acquired resistance in lung cancer and to derive potential treatments. In particular, I seek to understand why in the beginning distinct mechanisms of resistance are selected for by the same treatment and why finally increasing intra‐tumor heterogeneity limits the efficacy of targeted treatments in the clinical setting. Therefore, I first focused on the understanding of the biology of drug‐tolerant persister cells and pre‐existing resistant subclones using single cell transcriptomics in primary cell lines and patient‐derived cell models.

Besides this, I will continue to coordinate ongoing and future clinical projects, such as a phase II investigator‐initiated trial, that investigates the role of a new bispecific antibody in the treatment of resistance to EGFR-targeted drugs.

Unraveling the molecular pathogenesis of neuroblastoma using novel genetically engineered mouse models

 

One Fellow...Two Questions...

Anna-Maria, what was your motivation of becoming an EKFS fellow?

As a physician scientist, it is my firm belief that translational research is of upmost importance to the advancement of patients’ treatment in oncology.
The EKFS program is a powerful tool, that supports me as young clinician, by providing the opportunity to focus on my scientific career and to strengthen my scientific profile.The EKFS invests in the advancement of my research and professional development by providing protected research time, as well as excellent scientific education. Through its interdisciplinary design and close contact with other colleagues, it will broaden my scientific horizon and help me to work on my project successfully.
I am excited to be an EKFS fellow and to contribute to the challenge of decoding new mechanisms in cancer pathogenesis to improve cancer therapy in the future.

 

Where lie your clinical and scientific interests?

I have always been interested in the deeper understanding of molecular mechanisms in cancer and fascinated by the rapid progress in this field in recent years. Pediatric oncology offers the combination of taking good clinical care of the young patients and personally accompanying them and their families for a long period of time with ongoing scientific progress in the field. Unfortunately, treatment still remains challenging in a considerable set of our patients, who may go through multiple lines of treatment with limited chances of long-time survival. I am particularly interested in the pathogenesis of neuroblastoma, which is characterized by highly heterogenous clinical courses.
The focus of my project is to unravel new mechanisms of high-risk neuroblastoma pathogenesis, which contribute to this heterogeneity. Identification of new driver mutations would enable a deeper understanding of tumorigenesis and might enable new therapeutical approaches for this disease.

Spatial transcriptomics of esophageal adenocarcinomas: understanding the role of tumor architecture for stroma activity and treatment resistance

One Fellow...Two Questions...

Christoph, what was your motivation of becoming an EKFS fellow?

After three years of clinical training and simultaneous research, I plan to commit more time to projects that provide deeper insights into mechanisms of TME.
Also, becoming acquainted to novel, elaborate technologies will require a stronger focus on research for a defined period of time. The EKFS provides both the freedom to achieve these goals and a distinguished scientific framework.

I am now looking forward to be part of an interdisciplinary group that is focused on ambitious oncologic results.

Where lie your clinical and scientific interests?

Having the opportunity to visualize, analyze and understand the architecture and driver mechanisms of tumors has been the major reason to start my training in pathology.
Clinically, I followed the path towards the complex subtyping of salivary gland carcinomas (SGC) both morphologically and through molecular testing.
Recently, for the first time, we described the extracellular matrix composition of SGC using Nanostring and IHC/ISH. More recently, my focus broadened towards a training in GI pathology.
Scientifically, my overarching interest is to identify the complex interactions of cells within the tissue microenvironment (TME) of carcinomas.

As a next step, I would like to extend my field of research towards the TME of esophageal adenocarcinomas.
I am convinced that we should invest in understanding the spacial dimension to highly-plexed genetic and proteomic analysis which will fuel the discovery of novel cellular interactions.
