About

The primary objective is to assess the safety and efficacy of hypofractionated radiotherapy followed by hypo-boost combined with concurrent weekly chemotherapy in unresectable LA-NSCLC patients.

Full description

Patients receive four cycles of weekly docetaxel(25mg/㎡) and nedaplatin(25mg/㎡), each of 1 day's duration, concurrent with split-course thoracic radiotherapy of 40 Gy/10 fractions and 28 Gy/7 fractions administered in the first and second courses, respectively, with one-month break. The primary end point is progression-free survival, which is the time that passes from the first day of radiotherapy to the date at which disease progresses. Progression-free survival will be calculated using the Kaplan-Meier method.Toxicities will be graded according to CTCAE v. 4.0.

Experimental group

Description:

The radiotherapy is delivered using simultaneous integrated boost (SIB)-intensity-modulated radiotherapy (IMRT). Patients are irradiation at a palliative dose at the initial course: 40Gy/10f to gross tumor. The disease is re-evaluated one month after the end of the initial course using CT. The patient who achieved a partial remission according to the RECIST criteria and had a recovery of lung function should get the additional boost. At the second course, the tumor is re-simulated. The residual tumor was then treated with the second course of radiotherapy. A dose of 28Gy/7f is delivered to the residue tumor. Concurrent chemotherapy consists of weekly docetaxel(25mg/㎡) and nedaplatin(25mg/㎡), each of 1 day's duration.

Treatment:

Drug: concurrent chemotherapy

Radiation: split-course radiotherapy
