Hypofractionated Radiotherapy Followed by Hypo-boost for Local Advanced NSCLC

October 25, 2022 updated by: Hui Liu, Sun Yat-sen University

Hypofractionated Radiotherapy Followed by Hypofractionated Boost With Weekly Concurrent Chemotherapy for Unresectable Stage III Non-Small Cell Lung Cancer: A Prospective, Single Arm Phase II Study

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.

Study Overview

Detailed 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: split-course radiotherapy
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.
Patients are irradiation at a palliative dose at the initial course: 40Gy/10f to PTV-GTV. 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 repositioned and scanned. 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.
