Plasma miRNAs Predict Radiosensitivity of Different Fractionation Regimes in Palliative Radiotherapy for Advanced Non-small Cell Lung Cancer：Multicenter Controlled Study.(RadmiR-01)

Plasma miRNAs Predict Radiosensitivity of Different Fractionation Regimes in Palliative Radiotherapy for Advanced Non-small Cell Lung Cancer：Multicenter Controlled Study.

Lung cancer is a malignant tumor that causes the highest morbidity and mortality, and the main pathological type is non-small cell lung cancer (NSCLC). Most of them present with advanced stage at diagnosis. Radiotherapy is an important treatment strategy for advanced non-small cell lung cancer. However patients have different responses to radiotherapy due to individual differences, thus there is still lacking of sensitive markers to predict treatment response at present. Using bioinformatics to process the data and small sample clinical trial, our previous study found 5 plasma miRNAs were related to radiosensitivity. The design is controlled clinical trial. According to the size of lung lesions, the investigators divided the patients into hyperfractionated radiotherapy group（50Gy/11F/2W) with lesion ≤5cm in diameter and conventional fractionated radiotherapy group（60Gy/30F/6W）with lesion >5cm in diameter.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: hyperfractionated radiotherapy group; According to the size of lung lesions,we divided the patients with lesion ≤5cm in diameterand into hyperfractionated radiotherapy group（50Gy/11F/2W).	Radiation: radiotherapy; The patient in supine position with hands catch the plate column by crossing the head, and body fixed by vacuum mould. An enhanced 4DCT scan is conducted with a layer thickness and a distance each of 5 mm. the imaging information is input into the Eclipse program system,the gross tumor volume of the primary tumor (GTVt) and pathological lymph nodes (GTVn) are delineated,GTV is expanded in all 3D direction to create PGTV by 5mm margin for squamous cell carcinoma, or an 8mm margin for adenocarcinoma.Radiaion therapy is delivered by 5F-IMRT.For conventional fractionated radiotherapy,the prescribed dose covering 95% of PGTV is 60Gy/30F/6W.For hyperfractionated radiotherapy,the prescribed dose covering 95% of PGTV is 50Gy/11F/2W.lung V20 <25%, lung V30 <18%, spinal cord <36 Gy.
