Purpose : Oral capecitabine has demonstrated to be safe and efficient as neoadjuvant concurrent chemoradiotherapy (NCRT) for locally advanced rectal cancers. The aim of this study was to evaluate the long-term oncologic outcomes of NCRT with capecitabine and radical surgery.
Methods : From January 2000 to June 2010, 238 patients were treated at our center for locally advanced rectal cancers using conventional NCRT with capecitabine and radical surgery. Univariate and multivariate analyses were used to evaluate the factors associated with oncologic outcomes with log rank and Cox regression tests.
Results : The incidence of grade >3 capecitabine-related toxicity was found to be 4.6%. A pathologic complete response was observed in 14.7% of patients. The 5-year overall and 5-year disease-free survival rate, local and systemic recurrence rate were 82.8%, 75.1%, 4.8%, and 20.3%. Abdominoperineal resection and node-positive disease were independent prognostic factors of 5-year overall survival, 5-year disease-free survival, and systemic recurrence.
Conclusion : NCRT with capecitabine and radical surgery showed favorable long-term oncologic outcomes with benefits of acceptable toxicity and convenience. We suggest that capecitabine can be one of the favorable therapeutic options for NCRT in rectal cancer.
