Purpose: To analyze the treatment results of concurrent chemoradiation with oral 5-FU plus Gemcitabine or Paclitaxel for unresectable pancreatic cancer.

Materials & Methods: The patients, who were diagnosed by imaging modalities or by explo-laparotomy, were treated with concurrent chemoradiation. Radiotherapy was delivered to primary tumor and regional lymph nodes, and the total dose was 45
§í.
Patients received Gemcitabine 1,000 §·/§³ or Paclitaxel 50 §·/§³ weekly and oral 5-FU daily. The total number of cycles of chemotherapy ranged from 1 to 39 (median, 11 cycles). The follow-up period ranged from 6 to 36 months. Survival was analyzed
using
the Kaplan-Meier method.

Results: Fifty-four patients between Jan. 1999 to Nov. 2001 were included in this study. Forty-two patients who completed the planned treatment were included in this analysis. The patients' age ranged from 37 to 73 years (median, 60 years)
and
the male to female ratio was 30:12. Treatment was interrupted for 12 patients due to; disease progression for 6 (50%), poor performance status for 4 (33.3%), intercurrent disease for 1 (8.3%), and refusal for 1 (8.3%). Response evaluation was
possible
for 40 patients. One patient gained complete remission and 24 patients gained partial remission, hence the response rate was 59%. The survival rates were 46.7% and 17.0% at 1 year and 2 years, respectively with a median survival time of 12
months.
Patients treated with Paclitaxel showed superior outcomes compared to those patients treated with Gemcitabine, in terms of both response rate and survival rate although this difference was not statistically significant. Grade ¥² or ¥³ hematologic
toxicity was shown in 8 patients (19%), while grade ¥² or ¥³ non-hematologic toxicity was shown in 5 patients (12%).

Conclusion: Concurrent chemoradiation with oral 5-FU and Gemcitabine or Paclitaxel improves both the response rate and survival rate in patients with unresectable pancreatic cancer. A prospective study should be investigated in order to
improve
both the patient selection and the treatment outcome as well as to reduce the toxicity.
