There are many techniques that can be implemented to analyze tumors, “when we analyze the tumor, we use multiplex immunofluorescence which really helps us understand protein expression and cytopathology. “We have a project with Olink looking at a large panel of circulating proteins in the setting of immunotherapy response and resistance, and I think that this really has traction,” Boland adds. Cancers of the same grade and stage can have very different clinical outcomes, presumably because of distinct molecular differences. It is well established that detection of circulating tumor biomarkers in the blood can be useful for early cancer detection, supporting diagnosis and monitoring therapeutic response. To demonstrate the potential for proteomics in cancer diagnostics, Biognosys tested blood plasma samples taken from patients with non-small cell lung cancer (NSCLC). However, varying degrees of treatment response and resistance have been observed with these drugs, particularly in patients with advanced disease. It provides a precise readout of all the proteins and the sites within them that bind a particular compound, even in complex mixtures of cell extracts, including identifying undesired off-target binding events. We describe the various mass spectrometry-based approaches and highlight the challenges inherent in biomarker discovery studies. “I really think that what we’re learning from studying both the tumors and these blood-based biomarkers will hopefully feed back and inform risk stratification, even patient selection for therapy, and assist in monitoring patients over time.”. This work illustrates the suitability of next-generation proteomics for large clinical research projects, making large-scale multi-omics a reality.
