What this Trial Is About

Definitive radiotherapy is one of the important methods for inoperable locally advanced lung cancer. The recommended dose for definitive radiotherapy is 60-70Gy, and the optimal dose is still uncertain. Residual lesion after radiotherapy is a risk factor for recurrence. High doses to targeted tumor areas can effectively improve the local control rate, while minimizing toxic side effects. The regression pattern of primary lesions in lung caner after radiotherapy has not been clarified. This study intends to retrospectively collect clinical data of lung cancer patients with definitive radiotherapy, and explore the pattern of tumor regression after radiotherapy. It will help optimize the radiotherapy plan for lung cancer, so as to improve the efficacy and prognosis.
