The ADAURA adjuvant randomized trial demonstrated that osimertinib prolonged DFS. It has now been reported that health-related quality of life (HRQoL) was not adversely affected by adjuvant osimertinib. Does this mean that adjuvant osimertinib should now be standard as we await survival results? See related article by Majem et al., p. 2286.

Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) effectively treat EGFR-mutant lung adenocarcinoma, demonstrating initial efficacy but eventually leading to acquired resistance. Small cell transformation is a rare resistance mechanism to EGFR-TKIs in lung adenocarcinoma, which can complicate clinical diagnosis and treatment. We present a patient with lung adenocarcinoma who underwent a prior pneumonectomy and adjuvant chemotherapy and was treated with osimertinib after the recurrence of lung cancer.

Introduction: Treatment with adjuvant osimertinib for three years is the standard-of-care for resected stage IB-IIIA non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR)-mutations. The role of neoadjuvant osimertinib in the perioperative setting is yet to be elucidated in the NeoADAURA study (NCT04351555).
Methods: This is a single center, pilot study of patients with clinical stage IA-IIIA NSCLC (AJCC 8th edition) harboring an activating EGFR mutation (Exon 19 deletion, L858R) (NCT04816838).
Aims: We investigate the value of postoperative minimal residual disease (MRD) detection using circulating tumor DNA (ctDNA) in guiding adjuvant therapy for patients with potentially high recurrence risk in non-small cell lung cancer (NSCLC) due to the presence of MRD.
Patients And Methods: A randomized controlled trial will enroll stage IA-IIA NSCLC patients with Epidermal Growth Factor Receptor (EGFR) mutation and negative resection margins to evaluate the clinical value of MRD in guiding adjuvant osimertinib. That is, if the patient's peripheral blood does not show ctDNA (negative) after next generation sequencing (NGS) testing, postoperative observation and follow-up are sufficient.

Background: Although clinical trials of systemic chemotherapy for advanced non-small-cell lung cancer (NSCLC) have included both postoperative recurrence and de novo unresectable cases, postoperative recurrence is reported to have a better efficacy and prognosis. However, there are no efficacy data of first-line osimertinib for postoperative recurrence.
Methods: We conducted a post hoc analysis of a multicenter, prospective, observational study that evaluated the efficacy of first-line osimertinib in patients with epidermal growth factor receptor (EGFR)-positive NSCLC.

Background And Objective: Non-small cell lung cancer (NSCLC) in early-stages (I-IIIA) with epidermal growth factor receptor (EGFR) mutation may have specific epidemiological, clinical characteristics and treatment implications. This review aims to summarise the available evidence on these particularities, especially focusing on patient characteristics, treatment outcomes and safety with EGFR-tyrosine-kinase inhibitor (TKI).
Methods: An exhaustive search of international bibliographic databases, as well as in abstracts of communications from major international congresses was performed for evidence related to EGFR-mutated NSCLC or early-stage NSCLC published in English before December 31st, 2023.
