| Background: To investigate the role of surgical treatment for locally advanced esophageal cancer, we compared
the outcomes of chemoradiotheroy alone (CRT) to postoperative chemoradiotherapy (S/CRT), using, Regional
Radiotherapy Center, database. Materials and Methods: This retrospective study was conducted in North-West
of Iran, included of 255 consecutive patients with esophageal cancer. Eligible operable and non-operable, were
treated with S/CRT and CRT respectively. Radiotherapy (RT) was delivered at 1.8-2 Gy/day for fve consecutive
days in a given week. Chemotherapy (CT) consisted of cisplatin and 5-fluorouracil. Results: From March 2006
to March 2011 255 patients: male/female 129/96, median age 68 (35-90), squamous/adeno 213/12, received CRT
/S+CRT 166/59, median radiation dose 45±13.6Gy, Median survival 13.5 (11-15), overall survival (OS) One/
Two/Three 57/21/16%, Died/alive 158/97, Univariate analysis prognostic factors: age/stag/differentiation/dose of
RT/fraction/treatment, Multivariate analysis predictor factor: dose of RT/fraction. Conclusions: Although this
treatment offers some possibility for improvement of patients with esophageal cancer, there remains a signifcant
need for development of new drug and new therapeutic approaches that can substantially impact survival. |
