Purpose : This study was undertaken to evaluate the treatment outcome and side
effects of accelerated radiotherapy (RT) using concomitant boost for stage ¥² non-small
cell lung cancer (NSCLC).
Methods : Between April 1991 and December 1994, 102 patients with stage ¥² NSCLC
who had the favorable prognostic factors by CALGB criteria, were treated with
concomitant boost radiotherapy. Patients were treated with standard large fields to 54
Gy in 6 week. The boost treatment was administered concomitantly during the last 2
weeks with a dose of 13 Gy in 10 fractions. The interfraction interval was at least 6
hours. The total tumor dose was 66¡­70 Gy, given over 6 weeks.
Results : With 30 months¡¯ median follow-up period for survivors, median survival
was 15 months with 2 and 3-year overall survival rates of 34% and 19%, respectively
Thirty patients(29%) who had achieved complete remission after RT showed
significantly better 2-year survival rates than those without complete remission (58% vs
22%, p=0.001). Local failure and distant metastases as the first or only failure occurred
in 40 (44%) and 13(14%), respectively, and ultimate local and distant failure rates were
45% and 29%, respectively. Although Grade ¥³ esophageal complication of T-E fistula
was observed in one patient, most patients with pulmonary complication showed mild,
transient radiation pneumonitis.
Conclusion : This result suggests that the treatment of stage ¥² NSCLC with
concomitant boost RT may improve survival rates without enhanced radiation induced
toxicity compared with conventional RT. Further investigation of dose escalation by
conformal radiotherapy or combining chemotherapy and accelerated RT is warranted.
