What if a cancer treatment worked—until it suddenly didn’t? A new case report, “Acquired RUFY1-RET rearrangement as a mechanism of resistance to lorlatinib in a patient with CD74-ROS1 rearranged non-small cell lung cancer: A case report,” published in Oncotarget, reveals how a non-small cell lung cancer (NSCLC) patient developed drug resistance through a rare genetic alteration, allowing the cancer to evade therapy.
This unexpected finding highlights the importance of advanced genetic testing and personalized cancer treatments.
Non-Small Cell Lung Cancer, Targeted Therapy and Drug Resistance
Non-Small Cell Lung Cancer is the most common type of lung cancer, accounting for nearly 85% of all cases. Some patients with NSCLC have genetic mutations, such as ROS1 gene fusions, that drive tumor growth. These patients often respond well to targeted therapies like lorlatinib, a ROS1 inhibitor that blocks cancer growth.
However, cancer is constantly evolving. Over time, it can develop resistance to targeted therapies, leading to treatment failure. Understanding these resistance mechanisms is crucial for precision oncology, the approach of tailoring cancer treatment based on a patient’s unique genetic profile.
