Purpose : To evaluate survival rate and prognostic factors affecting survival of
patients with esophageal cancer treated with concurrent chemoradiation.
Materials and Methods : Eligibility included biopsy Proven invasive carcinoma of the
cervical or thoracic esophagus confined to esophagus and mediastinum with or without
regional lymph node and supraclavicular lymph node, and ECOG Performance status
Ho-Ha. Patients received radiation therapy with 5940cGy over 7 weeks and
chemotherapy, consisted of 5-FU(1000mg/m2/day in continuous infusion for
5 days, days 1 to 5 and days 29 to 33) and mitomycin C(8mg/m2
intravenous bolus at day 1). After concurrent chemoradiation maintenance chemotherapy
was followed with 5-FU(1000mg/m2/day in continuous infusion for 5 days
at 9th, 13th, and 17th weeks) and cisplatin(80mg/m2 intravenous bolus at
the first day of each cycle).
Results : From November 1989 to November 1995, 44 patients were entered in this
study. After treatment, complete response rate and partial response rate were 59% and
41% Overall 1, 2, and 5-year survivals were 59%, 38%, and 9.6%(median 17 months).
Prognostic factors affecting survival were response to treatment and T-stage. Among 26
complete responders, there were 6 local recurrences, 3 distant recurrences, 1 local and
distant recurrence, and 2 unknown site recurrences. Acute and chronic complication rates
with grade 3 or more were 20% and 13.6% and there was no treatment-related
mortality.
Conclusion : Concurrent chemoradiation, compared with historical control groups that
treated with radiation alone, improved median survival and did not significantly increase
treatment-related complications. Complete responders had longer survival duration than
partial responders. Predominant failure pattern was local failure. So efforts of improve
local control should be proposed.
