A groundbreaking real-world study by Providence, Illumina (NASDAQ: ILMN), and Microsoft Research demonstrates that early Comprehensive Genomic Profiling (CGP) in cancer diagnosis significantly improves personalized treatment and patient outcomes. Published in *Journal of Clinical Oncology - Oncology Practice (JCO-OP)*, the first two years of this five-year study analyzed 3,216 advanced cancer patients.
The study used pathologist-driven CGP testing, delivering results 12 days before patients’ initial oncologist visits. This facilitated earlier, biomarker-informed decisions, with over half of the patients receiving targeted therapy or immunotherapy. Patients on targeted therapy achieved significantly longer survival (25 months) compared to those on chemotherapy alone (17 months, p<0.001).
Key findings include:
- CGP identified actionable mutations in 67% of tumors, compared to 33% with small-panel tests.
- 52% of CGP-tested patients received matched precision therapies, versus 32% receiving chemotherapy.
For non-small-cell lung cancer (NSCLC) patients, a related study revealed CGP's superior performance over small-panel tests, with higher actionable mutation rates (77% vs. 63%), greater use of matched therapies (64% vs. 50%), and improved survival (16 months vs. 7 months, p<0.0001).
Dr. Carlo Bifulco of Providence Genomics emphasized integrating CGP into standard care, as earlier biomarker-matched treatments significantly improve outcomes. CGP’s broad scope and faster results make it a vital tool in oncology, though barriers like insurance coverage persist.
Leveraging AI by Microsoft Research streamlined genomic interpretation and trial matching, expediting insights for molecular tumor boards. “This paradigm shift in oncology ensures better patient outcomes,” said Swaroop Aradhya of Illumina.
The findings advocate for widespread CGP adoption, highlighting its role in improving survival and driving precision oncology forward.
