Purpose : We performed this study to evaluate the prognostic factors and the effect of
induction chemotherapy in locally advanced non-small cell lung cancel (NSCLC).
Materials and Methods : A retrospective analysis was done for 130 patients with
locally advanced NSCLC treated with curative radiotherapy alone or induction
chemo-radiotherapy from January 1986 to October 1996. Eighty-five patients were
treated with radiotherapy alone, forty-five with induction chemotherapy and radiotherapy.
Age, sex, performance status, histopathologic type, and stage were evenly distributed in
both groups. The patients were treated with 6 MV or 10 MV X-ray. Conventional
fractionation with daily fraction size 1.8¡­2.0 §í was done. Of the patients, 129 patients
received total dose above 59.6 §í (56¡­66 §í, median 60 §í). Induction chemotherapy
regimen were CAP (Cyclophosphamide, Adriamycin, Cisplatin) in 6 patients, MVP
(Mitomycin, Vinblastine, Cisplatin) in 9 patients, MIC (Mitomycin, Ifosfamide Cisplatin)
in 13 patients, and EP (Etoposide, Cisplatin) in 17 patients. Chemotherapy was done in
2¡­5 cycles (median 2).
Results : Overall 1-, 2-, and 3-year survival rate (YSR) for all patients were 41.5%,
13.7%, and 7%, respectively (median survival time 11 months). According to treatment
modality, median survival time, overall 1-, 2-, and 3-YSR were 9 months, 32.9%, 10.5%,
6% for radiotherapy alone group, and 14 months, 57.8%, 20%, 7.6% for induction
chemotherapy group, respectively (p=0.0005). Complete response (CR) to overall
treatments was 25% (21/84) in radiotherapy alone and 40.5% (17/42) in induction
chemotherapy group (P=0.09). The Prognostic factors affecting overall survival were
hemoglobin level (p=0.04), NSE (neuron-specific enolase) level (p=0.004), and response to
overall treatment(p=0.004). According to treatment modalities, NSE (neuron-specific
enolase) (p=0.006) and response to overall treatment (p=0.003) were associated with
overall survival in radiotherapy alone group, and response to overall treatment (p=0.007)
in induction chemotherapy group. The failure pattern analysis revealed no significant
difference between treatment modalities. But, in patients with CR to overall treatment,
distant metastasis were found in 11/19 patients with radiotherapy alone, arid 3/13
patients with induction chemotherapy and radiotherapy (p=0.07). Locoregional failure
patterns were not different between two groups (10/19 vs 6/13).
Conclusion : Induction chemotherapy and radiotherapy achieved increased 2YSR
compared to radio-therapy alone. At least in CR patients, there was decreased tendency
in distant metastasis with induction chemotherapy But, locoregional failures and
long-term survival were not improved. Thus, there is need of more effort to increasing
local control and further decreasing distant metastasis.
