Predictors, surrogate, and patient-reported outcomes in immunotherapy and salvage surgery for unresectable lung cancer: a single-center retrospective study

Revamping Non-Small Cell Lung Cancer Treatments in Stages II and III: Preparing Healthcare for Cutting-Edge Immuno-Oncology Regimens

Non-small cell lung cancer (NSCLC) poses a significant challenge in clinical oncology, necessitating continual refinement of treatment approaches in stages II and III. Recent advancements have highlighted the potential of neoadjuvant therapy in optimising patient outcomes. Biomarker testing guides neoadjuvant therapy decisions, including epidermal growth factor receptor (EGFR) mutation and programmed death-ligand 1 (PD-L1) expression testing. Neoadjuvant therapy aims to improve oncological outcomes by treating micrometastatic disease and assessing tumour response before surgery. Disease-free survival is a surrogate endpoint for overall survival in both neoadjuvant and adjuvant settings. Multidisciplinary collaboration is crucial for individualised treatment planning and optimising patient care. The management of NSCLC requires a comprehensive approach, integrating expertise across disciplines and tailoring treatment strategies to individual patient needs. Neoadjuvant therapy shows promise in improving long-term outcomes, with biomarker testing guiding treatment decisions. Challenges such as defining borderline resectability and differentiating pseudoprogression highlight the need for ongoing research and collaboration.

Multi-omics integrative modelling for stereotactic body radiotherapy in early-stage non-small cell lung cancer: clinical trial protocol of the MONDRIAN study

BACKGROUND

Currently, main treatment strategies for early-stage non-small cell lung cancer (ES-NSCLC) disease are surgery or stereotactic body radiation therapy (SBRT), with successful local control rates for both approaches. However, regional and distant failure remain critical in SBRT, and it is paramount to identify predictive factors of response to identify high-risk patients who may benefit from more aggressive approaches. The main endpoint of the MONDRIAN trial is to identify multi-omic biomarkers of SBRT response integrating information from the individual fields of radiomics, genomics and proteomics.

METHODS

MONDRIAN is a prospective observational explorative cohort clinical study, with a data-driven, bottom-up approach. It is expected to enroll 100 ES-NSCLC SBRT candidates treated at an Italian tertiary cancer center with well-recognized expertise in SBRT and thoracic surgery. To identify predictors specific to SBRT, MONDRIAN will include data from 200 patients treated with surgery, in a 1:2 ratio, with comparable clinical characteristics. The project will have an overall expected duration of 60 months, and will be structured into five main tasks: (i) Clinical Study; (ii) Imaging/ Radiomic Study, (iii) Gene Expression Study, (iv) Proteomic Study, (v) Integrative Model Building.

DISCUSSION

Thanks to its multi-disciplinary nature, MONDRIAN is expected to provide the opportunity to characterize ES-NSCLC from a multi-omic perspective, with a Radiation Oncology-oriented focus. Other than contributing to a mechanistic understanding of the disease, the study will assist the identification of high-risk patients in a largely unexplored clinical setting. Ultimately, this would orient further clinical research efforts on the combination of SBRT and systemic treatments, such as immunotherapy, with the perspective of improving oncological outcomes in this subset of patients.

TRIAL REGISTRATION

The study was prospectively registered at clinicaltrials.gov (NCT05974475).
