Purpose : This study was performed to analyze the efficacy of induction chemotherapy
followed by radiation therapy in locally advanced non-small cell lung cancer.
Materials and Methods : Eighty patients with locally advanced non-small cell lung
cancer treated from 1989 to 1995 at Pusan Paik hospital were analyzed retrospectively.
Twenty-one patients were treated with induction chemotherapy followed by radiation
therapy and Fifty-nine patients were treated with radiation therapy alone. Chemotherapy
regimen consisted of cisplatin-based combination(2 or 3 drugs). All Patients were treated
by Co-60 or 6 MV linear accelerators. Radiation dose ranged from 50 Gy to 80 Gy
(median, 64.8 Gy). We evaluated response rate, survival rate, and pattern of failure in
both treatment groups.
Conclusion : Overall response rate in induction chemotherapy group and radiotherapy
alone group were 48% and 45%, respectively. Of the 80 patients, 46 patients were
evaluable for pattern of failure. Initial failure pattern in induction chemotherapy group
was as follows 8 (67%) at locoregional, 4 (33) in distant metastasis. Radiation alone
group was 21 (71%) and 5 (29%), respectively Results showed no difference of distant
failure between induction chemotherapy group and radiation alone grouts. The 1 and 2
year survival rate in induction chemotherapy group were 43% and 14%, respectively and
in radiotherapy alone group, 31% and 7%, respectively (p=0 135).
Conclusion : In stage ¥² nor-small cell lung cancer, induction chemotherapy and
radiation therapy showed increased tendency in survival with no statistical significance,
Induction chemotherapy seems to have no effect of decreasing distant failure and no
survival advantage compared with radiotherapy alone.
