A new study published in Oncotarget’s Volume 15 on October 11, 2024, titled “Relationship between the expressions of DLL3, ASC1, TTF-1 and Ki-67: First steps of precision medicine at SCLC,” reveals promising insights into small cell lung cancer (SCLC), one of the deadliest forms of lung cancer with limited treatment options.
Led by researchers from the Federal University of Ceará in Brazil, along with teams from Argentina and Spain, the study explores how specific biomarkers in SCLC tumors could pave the way for more personalized treatments. SCLC, which makes up about 15% of lung cancer cases, is notorious for its rapid growth and resistance to treatment. The five-year survival rate for SCLC patients remains below 5%. However, advances in precision medicine aim to improve these odds by targeting the unique characteristics of each patient’s tumor.
The research team, including Samuel Silva, Juliana C. Sousa, Cleto Nogueira, Raquel Feijo, Francisco Martins Neto, Laura Cardoso Marinho, Guilherme Sousa, Valeria Denninghoff, and Fabio Tavora, analyzed tumor samples from 64 SCLC patients using traditional and digital pathology techniques. Their findings highlighted two key biomarkers—Delta-like ligand 3 (DLL3) and Thyroid transcription factor-1 (TTF-1)—as particularly significant.
DLL3 was found in more than 70% of the tumors, suggesting its potential as a target for therapies such as Tarlatamab. Meanwhile, TTF-1 expression was linked to better survival rates, positioning it as a useful prognostic marker for predicting patient outcomes and refining diagnoses.
The researchers also emphasized the role of digital pathology software, QuPath, in improving analysis accuracy. This tool allowed for detailed morphometric studies that could help tailor treatments to individual patients.
In conclusion, the study suggests that clinical trials targeting biomarkers like DLL3 and TTF-1 could improve patient outcomes by personalizing treatment plans. This research represents a significant step forward in the application of precision medicine to treat SCLC.
