Accelereated hyperfractionated with uneven crushing daily dose with chemoradiation treatment of inoperable non-small cell lung cancer

This study presents the results of chemoradiation treatment with accelerated hyperfractionated regime with uneven crushing daily dose in patients with unresectable non-small cell lung cancer. The study included 187 patients with confirmed diagnosis of non-small cell lung cancer. Patients were divided into three groups: the first (control) group included 75 patients who underwent radiotherapy in conventional fractionation regimen (60-66 Gy in 30-33 daily fractions) with sequential 2-4 cycles of chemotherapy of cisplatin + etoposide. In the second (intermediate group) included 66 patients who underwent radiation therapy to hyperfractionated accelerated regimen (1 Gy and 1.5 Gy b.i.d. in 48-56 fractions) with sequential 2-4 cycles of chemotherapy of cisplatin + etoposide. In the third (main) group consisted of 46 patients who underwent radiation therapy to hyperfractionated accelerated regimen (1 Gy and 1.5 Gy b.i.d. in 48-56 fractions) with simultaneous 2 cycles of cisplatin + etoposide. Complete and partial response rate was 60.0 % in the control group, 89.4 % in the intermediate group and 76.0 % in the study group. Five-year overall and disease-free survival rates were in control, intermediate and main groups, 6.6 %, 10.5 %, 21.4 % and 2.5 %, 10.1 %, 16.4 %, respectively.
