Selecting Patients with Advanced NSCLC for Chemo
JAMA Oncol; ePub 2017 Nov 1; Shen, Chang, et al
Certain small metabolites could serve as useful biomarkers to help select ideal candidates for platinum-based chemotherapy in patients with non-small cell lung cancer (NSCLC), according to a study involving 220 individuals. Participants had advanced-stage NSCLC with either poor (n=110) or good survival (n=110). Investigators performed metabolomic profiling and then looked at the link between certain metabolites and survival during discovery and validation phases. Among the results:
- The levels of caffeine, paraxanthine, stachydrine, and methyl glucopyranoside (alpha + beta) metabolites were substantially different between patients with poor and good survival during both discovery and validation.
- Increased levels of the 4 metabolites were significantly linked with good survival in both discovery and validation phases.
- Strong cumulative effects on overall survival were also seen.
