Positive data has been building for regimens, which combine platinum-based chemotherapy with anti-PD-L1 immunotherapy. 'To identify these CPR patients is key, since achieving CPR is associated with improved survival,' Alberto Cruz-Bermudez, a researcher at Puerta de Hierro Majadahonda University Hospital in Madrid and co-first author on the study, said in an email.ДЄccording to Bermudez, the success of immunotherapy in later-stage lung cancer has raised hopes that the same drugs can also impact patient outcomes when the disease is identified early.

Using T-cell receptor sequencing on samples from 40 non-small cell lung cancer patients in the Phase II NADIM trial, the team identified two biomarker signatures - a domination of the TCR repertoire by the top 1 percent of clones, and overall TCR 'evenness'В - that predicted which patients would be free of disease when they received surgery. The group published their findings in Clinical Cancer Research last month and are now hoping to validate them in a larger patient cohort with longer follow-up and survival data, which could support clinical translation. NEW YORK вЂ“ Anticipating future approvals for neoadjuvant chemoimmunotherapy in early-stage lung cancer, a team of Spanish investigators has identified a promising biomarker signature based on genomic analysis of the T cell receptor repertoire, which outperformed existing predictors like tumor mutational burdenВ and PD-L1.
