Dr Jack West of City of Hope Comprehensive Cancer Center in Duarte, California, discusses key presentations on early-stage non–small lung cancer (NSCLC) from the 2022 European Society for Medical Oncology Congress.

He begins by reporting on 2 years of additional follow-up from the ADAURA trial, which looked at osimertinib as adjuvant therapy in patients with resected EGFR-mutated disease. The results raise the question of whether the drug needs to be given indefinitely.

Next, he discusses an analysis of data from the ADAURA trial that looked at longitudinal monitoring of circulating tumor DNA (ctDNA) levels. This revealed that both baseline ctDNA and ctDNA clearance were predictive of later recurrence.

Dr West moves on to a large global study that demonstrated a clear link between air pollution and lung cancer. Pollution was shown to be a tumor promoter of rare driver mutations in normal lung tissue.

After discussing disappointing data from CANOPY-A indicating that adjuvant canakinumab does not improve survival outcomes, he closes with an examination of the PATHFINDER study. This involved more than 6600 patients who were screened for cancer after a single blood test. Although the study identified cancer in 1.4% of participants, the low positive predictive value raises questions over the wider application of this test.
