Brief Summary
Lung cancer presents a significant treatment challenge, particularly in the heterogeneous stage III NSCLC patient population. While chemotherapy combined with high-dose radiotherapy (60 Gy in 30 fractions of 2 Gy once daily) is currently the recommended approach for unresectable stage III cases, it is associated with significant rates of locoregional and distant failures. Notably, the introduction of durvalumab consolidation therapy after chemoradiotherapy (CRT), as demonstrated in the PACIFIC study, has shown improved overall survival, primarily attributed to enhanced distant control. This improvement prompts further interest in investigating whether further improvements in locoregional control can lead to improved survival for patients. The present study aims to evaluate the feasibility of post-CRT surgery in patients with initially considered unresectable stage III (non-N3) NSCLC.

Interventions
Patients with initially unresectable stage III NSCLC will undergo surgery after chemoradiotherapy completion when the tumor is deemed resectable by the thoracic oncology tumor board and will then receive durvalumab
Eligibility Criteria
You may qualify if:
- Histologically or cytologically confirmed stage III (non-N3) NSCLC (TNM 8th edition), before start of concurrent chemoradiotherapy (CRT).
- In case of suspected N2-disease, mediastinal invasive staging (EUS, EBUS and/or mediastinoscopy) to prove N2 involvement before start of concurrent CRT is preferred.
- Initial MDT recommendation for a non-surgical treatment comprising concurrent CRT (platinum-doublet, 60 Gy in 30 fractions of 2 Gy once daily) followed by durvalumab
- Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Written informed consent and any locally required authorization (eg, European Union \[EU\] Data Privacy Directive in the EU) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations.
- Age \> 18 years at time of study entry, i.e. the day of signing informed consent.
- Have a performance status of 0-1 on the ECOG Performance Scale at time of restaging.
- Body weight \>30 kg
- Demonstrate adequate normal organ and marrow function, as deemed acceptable by the treating physician in the context of CRT.
- Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
- Must have a life expectancy of at least 12 weeks
You may not qualify if:
- Patients with TxN3 or M1 disease
- Patients with known actionable genomic alterations.
- The use of any CRT schemes other than those in ESMO recommendations (platinum doublet, 30 once-daily fractions of 2 Gy)
- Patients deemed inoperable based on cardiopulmonary function tests or comorbidity
- Unable to undergo CT-scan with iv-contrast
- Unable to remain supine for 15 min for the PET-low-dose CT scan
- Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways.
- Participation in another clinical study with an investigational product during the last 4 weeks.
- Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study
- Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
- Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.
- Receipt of the last dose of anticancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies) ≤4 weeks prior to the first dose of study drug. If sufficient wash-out time has not occurred due to the schedule or PK properties of an agent, a longer wash-out period will be required, as agreed by AstraZeneca/MedImmune and the investigator.
- Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.
- Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP.
- History of allogenic organ transplantation.
