Dr. Jessica Lin is medical oncologist and a translational and clinical investigator in the Thoracic Oncology Program and the Henri and Belinda Termeer Center for Targeted Therapies at Massachusetts General Hospital (MGH).
With NFCR support, Dr. Lin collaborates with physician-scientist, Dr. Aaron Hata at Harvard on a project aimed to identify the major ‘drivers’ of resistance to tyrosine kinase inhibitors (TKIs) in non-small cell lung cancer (NSCLC) patients with mutations in the ALK gene (called ALK positive or ALK+.) ALK+ patients eventually experience drug resistance to the 1st, 2nd, and 3rd line TKI therapies. Moreover, in ALK+-cancer cells, ALK-independent pathways can begin to signal abnormal growth.
Therefore, a significant challenge continues in the ability to match each patient with the therapy that is most likely to be effective.
The collaborative team of Lin and Hata are using an innovative and cutting-edge gene expression technology called ‘digital spatial profiling’ to identify the drivers of drug-resistance in ALK+ NSCLC. Combining powerful gene expression profiling with spatial resolution in the cell, digital spatial profiling analyzes approximately 1800 cancer-associated genes from multiple distinct regions in the biopsy sample. The technology also characterizes tumor cells, immune cells and fibroblasts in multiple regions of the tumor biopsy. Previously this type of detailed and systematic analysis was not feasible in standard biopsy samples.
Significantly, their research may develop and confirm the new method can optimally match the right therapy to each patient with advanced ALK+ lung cancer and at the time when resistance occurs.
