Key Differences Between ESMO 2025 and Previous Recommendations for Early-Stage and Locally Advanced NSCLC
We have previously published a structured summary of ESMO's recommendations for the management of non-small cell lung cancer (NSCLC), which have evolved considerably this year, marking a major turning point in the perioperative therapeutic approach. The most significant changes of these new guidelines focus on the integration of immunotherapy in neoadjuvant and adjuvant strategies.
Evolution Towards Perioperative Immunotherapy
New Recommendations for Neoadjuvant Immunotherapy
New 2025 guidelines mark the definitive adoption of immunotherapy in combination with chemotherapy in neoadjuvant treatment. This evolution is based on compelling results from several pivotal studies:[1]
[2]
- - CheckMate 816: The combination of nivolumab plus platinum-based chemotherapy demonstrated a significant progression-free survival benefit (HR 0.63) and final overall survival (HR 0.72) [3][4]
- - KEYNOTE-671: Perioperative pembrolizumab showed improved event-free survival with an HR of 0.57 and overall survival benefit[5][6]
Changes in Eligibility Criteria
Unlike previous recommendations that limited neoadjuvant immunotherapy to patients with PD-L1 ≥1%, the new 2025 guidelines extend this approach to all eligible patients, including those with PD-L1 <1%. This extension is supported by recent meta-analyses demonstrating an event-free survival benefit even in this subpopulation (HR 0.74).[7]
[8]Evolution of Adjuvant Targeted Therapies
Expansion of Osimertinib Indications
The 2025 recommendations consolidate and extend the use of adjuvant osimertinib for patients with EGFR mutations. New data from the ADAURA study show: [9]
[10]
- - 4-year disease-free survival benefit of 73% versus 38% with placebo
- - 73% reduction in recurrence risk (HR 0.27) [10]
An important new indication has been approved for osimertinib in unresectable locally advanced (stage III) cancer after chemoradiotherapy, with a remarkable progression-free survival benefit (39.1 months versus 5.6 months). [11]
[12]Changes in Diagnostic Approach and Biomarkers
The Strengthening of Molecular Testing
The 2025 guidelines place greater emphasis on the importance of comprehensive molecular testing before treatment initiation, particularly in never-smokers where the frequency of targetable alterations is very high (EGFR 52%, ALK 8%).
[13]Integration of Liquid Biopsy
Despite suboptimal sensitivity in current assays, with a large proportion of false-negative results in patients that subsequently experience recurrence. ESMO gives a conclusion that currently available assays are prognostic but not predictive of treatment outcomes and cannot be used for treatment de-escalation after curative-intent therapy at this time. Further technological advances are needed before clinical implementation. Finally, the use of circulating tumor DNA is now better integrated into recommendations, particularly for resistance detection and therapeutic monitoring. [14]
[10]Noteworthy, ESMO's 2025 guidelines seamlessly align with major liquid biopsy programs across Europe, integrating ctDNA testing into routine NSCLC care.
The NHS leads globally with its "blood test–first" model, offering liquid biopsies to 15,000 lung cancer patients annually and reducing turnaround by two weeks. France’s Plan Médecine Génomique 2025 invested €239 million, enabling in-house testing via FoundationOne Liquid CDx at Gustave Roussy. Germany’s robust reimbursement framework underpins a $940.9 million market in 2024, projected to $1.75 billion by 2030. Spain’s Vall d’Hebron Institute hosts Europe’s first Guardant Health service, while Italy’s GerSom initiative offers combined somatic/germline profiling of 467 genes. The European Liquid Biopsy Society (93 institutions in 21 countries) standardizes implementation and tackles IVDR compliance and reimbursement. A $1.24 billion European market in 2024, forecast to $5.58 billion by 2033, provides the commercial foundation supporting these clinical efforts. One can easily picture that the integration of liquid biopsies in the guidelines will have strong consequences in terms of common law coverage of this molecular screening technique in Europe.
Changes in Treatment Stratification
New Therapeutic Hierarchy
The 2025 recommendations establish a clear hierarchy of approaches:
- Patients with EGFR mutations: Adjuvant osimertinib remains the standard for resectable stages IB-IIIA
- Patients without targetable mutations: Neoadjuvant chemoimmunotherapy becomes the preferred approach for stages II-IIIA
- Perioperative approach: Preference for neoadjuvant chemoimmunotherapy followed by adjuvant immunotherapy.
Different Regional Regulatoy Approaches
The 2025 recommendations reflect approval disparities between the EMA and FDA. While the FDA approves neoadjuvant immunotherapy for all eligible patients, the EMA maintains a restriction to patients with PD-L1 ≥1%, creating access differences in Europe. [8][3]
[7]Impact on Clinical Management
New Practical Considerations
The 2025 guidelines integrate new practical considerations:
- - Assessment of pathological response as an important endpoint (MPR and pCR)
- - Management of perioperative immunological toxicities
- - Importance of surgical timing after neoadjuvant chemoimmunotherapy
- - Post-operative surveillance adapted to new treatments
Considering treatment duration and sequencing, the new recommendations specify the following optimal durations:
- - 3-4 cycles of neoadjuvant before surgery
- - Continuation of adjuvant immunotherapy up to 1 year after surgery
- - Need for multidisciplinary evaluation to optimize sequencing [15][5]
These developments represent a major paradigm shift towards a personalized approach that systematically integrates biomarkers and prioritizes perioperative strategies to improve outcomes for patients with early-stage and locally advanced NSCLC.
