A multicentre single arm phase II trial assessing the efficacy of immunotherapy, chemotherapy and stereotactic radiotherapy to metastases followed by definitive surgery or radiotherapy to the primary tumour, in patients with synchronous oligo-metastatic non-small cell lung cancer
CHESS: Immunotherapy, Chemotherapy, Radiotherapy and Surgery for Synchronous Oligo-metastatic NSCLC
Immunotherapy has substantially improved the outcome in metastatic NSCLC and has become first-line treatment of choice in patients with high PD-L1 expression and without EGFR or ALK mutations. However, only about one-third of NSCLC patients present a PD-L1 expression of ≥50%, excluding most patients from first-line immunotherapy. Various strategies are currently pursued to increase the number of patients that may benefit from immunotherapy and to further improve the outcome of patients with metastatic NSCLC.
The CHESS trial builds on encouraging data from combined chemo-radiotherapy with immune-checkpoint inhibitors and the excellent local control provided by radiotherapy and surgery.
