arms: paclitaxel 45mg/m2 /week (TP), docetaxel 20mg/m2 /week (DP), gemcitabine
350mg/m2 /week (GP) in addition to cisplatin 20mg/m2 /week. Three-dimensional
conformal radiotherapy (3DCRT) was given once daily, 2-2.4Gy fraction to the
GTV, weekly 5 fractions and the total prescription dose was over 60 Gy. Four
weeks after the completion of CCRT, we proceeded to the three weekly consoli-
dation chemotherapy. The primary end-point was response rate and the secondary
end-points were survival and toxicity.
Results: For this preliminary analysis, we included the fifty-one patients (TP: 19,
DP: 14, GP: 18). Similar overall response rates are observed; TP: 94.7%, GP:
92.9%, DP: 94.4%, respectively (p=1.0). There is no significant difference in me-
dian survival; TP: not reached, GP: 13 months, DP: not reached (p=0.31). Radiation
esophagitis (≥grade 2) was noted in 5%(TP), 3%(DP), and 8%(GP, p=0.673) and
radiation pneumonitis (≥grade 2) was observed in 2%(TP), 0%(DP), and 6%(GP,
p=0.017). During the CCRT, both hematologic (p=0.31) and non-hematologic
toxicities (p=0.27) were not different in three arms.
Conclusions: Among the 3 arms, no significant difference in response rate and
survival is observed. Tendency of different toxicity profiles are being observed.
