Main barriers in the treatment of stage III non-small cell lung cancer found by our panel of experts
| Main barriers | |
|---|---|
| 1. | Low chemoradiotherapy rates due to long waiting times for radiotherapy, especially for advanced RT techniques and/or radiotherapy and chemotherapy performed by different institutions. |
| 2. | Long referral process among different specialities (general practitioner, pneumologist, medical oncologist, radiotherapist). |
| 3. | Poor health literacy and social status of patients influence awareness of lung cancer symptoms, risk factors and treatment. |
| 4. | Late access to imaging and diagnostic procedures, especially PET-CT – long waiting times, low capacity. |
| 5. | Barriers to implementing targeted population screening programs. |

Evidence based clinical recommendations consensus
| Statement | 1st round average N = 9 | Final consensus | |
|---|---|---|---|
| 1. | All patients planned for stage III NSCLC treatment should undergo a diagnostic contrast-enhanced CT scan of the chest and upper abdomen followed by a PET or a combined PET-CT using a CT technique with adequately high resolution for initial staging purposes. | 4.8 | Consensus |
| 2. | All patients planned for curative stage III NSCLC treatment should receive brain imaging for initial staging. | 4.8 | Consensus |
| 3. | Concurrent CRT is the treatment of choice in patients evaluated as unresectable in stage IIIa, IIIb, and IIIc. | 4.6 | Consensus |
| 4. | If concurrent CRT is not possible - for any reason - sequential ChT followed by definitive RT represents a valid and effective alternative. | 4.8 | Consensus |
| 5. | An experienced multidisciplinary team is of paramount importance in any complex multimodality treatment strategy decision. | 4.9 | Consensus |
| 6. | In the absence of contraindications, the optimal ChT to be combined with radiation in stage III NSCLC should be platinum-based therapy. | 4.3 | Consensus |
| 7. | When delivered perioperatively, platinum-based combinations are considered the treatment of choice, in the absence of contraindications. | 4.6 | Consensus |
| 8. | In the stage III disease CRT strategy, two to four cycles of concomitant ChT should be delivered. | 4.9 | Consensus |
| 9. | In the perioperative setting, three to four cycles of platinum-based ChT are recommended. | 4.8 | Consensus |
| 10. | 60–66 Gy in 30–33 daily fractions is recommended for concurrent CRT. The maximum overall treatment time should not exceed 7 weeks. | 5.0 | Unanimity |
| 11. | In sequential approaches, RT delivered over a short overall treatment time is recommended. | 4.3 | Consensus |
| 12. | Adjuvant anti PD-L1 checkpoint inhibitor durvalumab is indicated for unresectable NSCLC with PD-L1 ≥ 1% without progression after chemoradiotherapy with a platinum-based regime. | 5.0 | Unanimity |
