ABSTRACT

Background and objectivesThis study is to evaluate the safety and efficacy of preoperative radiotherapy (RT) combined with bolus infusional 5-fluorouracil (5-FU) or oral capecitabine in patients with locally advanced rectal cancer (LARC).Materials and methodsSeventy-four patients were retrospectively analyzed. Twenty-seven patients were treated with 5-FU (350 mg/m2 IV bolus) and leucovorin (20 mg/m2 IV bolus) for 5 days/week during week 1 and 5 of RT. Forty-seven patients were treated with capecitabine (850 mg/m2, twice daily for 5 days/week). Both groups received the same RT course (45–50.4 Gy/25 fractions, 5 days/week, for 5 weeks). Patients underwent surgery in 6 weeks after completion of the chemoradiotherapy. Data of the observational study were collected.ResultsGrade 3 or 4 toxicities occurred in 40.7% (5-FU) and 19.1% (capecitabine) of the patients (P = 0.044). Six patients in the 5-FU group (22.2%) and six patients in the capecitabine group (14%) achieved complete response. Primary tumor (T) downstaging were achieved in 51.9% (5-FU) and 69.8% (capecitabine) of the patients. The pathological ypT0-2 stage was 40.7% (5-FU) and 67.4% (capecitabine) (P = 0.028).ConclusionsIn consideration of the better ypT0-2 downstaging rate, less severe toxicities, and no need for indwelling intravenous device on oral capecitabine regimen, the administration of oral capecitabine with RT may be a more favorable option in the neoadjuvant treatment for LARC.

Twenty-seven patients were treated with 5-FU (350\u00a0mg/m2 IV bolus) and leucovorin (20\u00a0mg/m2 IV bolus) for 5\u00a0days/week during week 1 and 5 of RT. Forty-seven patients were treated with capecitabine (850\u00a0mg/m2, twice daily for 5\u00a0days/week). Both groups received the same RT course (45\u201350.4\u00a0Gy/25 fractions, 5\u00a0days/week, for 5\u00a0weeks). Patients underwent surgery in 6\u00a0weeks after completion of the chemoradiotherapy. Data of the observational study were collected.ResultsGrade 3 or 4 toxicities occurred in 40.7% (5-FU) and 19.1% (capecitabine) of the patients (P\u2009=\u20090.044). Six patients in the 5-FU group (22.2%) and six patients in the capecitabine group (14%) achieved complete response. Primary tumor (T) downstaging were achieved in 51.9% (5-FU) and 69.8% (capecitabine) of the patients. The pathological ypT0-2 stage was 40.7% (5-FU) and 67.4% (capecitabine) (P\u2009=\u20090.028).ConclusionsIn consideration of the better ypT0-2 downstaging rate, less severe toxicities, and no need for indwelling intravenous device on oral capecitabine regimen, the administration of oral capecitabine with RT may be a more favorable option in the neoadjuvant treatment for LARC.",

28 schema:description Background and objectivesThis study is to evaluate the safety and efficacy of preoperative radiotherapy (RT) combined with bolus infusional 5-fluorouracil (5-FU) or oral capecitabine in patients with locally advanced rectal cancer (LARC).Materials and methodsSeventy-four patients were retrospectively analyzed. Twenty-seven patients were treated with 5-FU (350 mg/m2 IV bolus) and leucovorin (20 mg/m2 IV bolus) for 5 days/week during week 1 and 5 of RT. Forty-seven patients were treated with capecitabine (850 mg/m2, twice daily for 5 days/week). Both groups received the same RT course (45–50.4 Gy/25 fractions, 5 days/week, for 5 weeks). Patients underwent surgery in 6 weeks after completion of the chemoradiotherapy. Data of the observational study were collected.ResultsGrade 3 or 4 toxicities occurred in 40.7% (5-FU) and 19.1% (capecitabine) of the patients (P = 0.044). Six patients in the 5-FU group (22.2%) and six patients in the capecitabine group (14%) achieved complete response. Primary tumor (T) downstaging were achieved in 51.9% (5-FU) and 69.8% (capecitabine) of the patients. The pathological ypT0-2 stage was 40.7% (5-FU) and 67.4% (capecitabine) (P = 0.028).ConclusionsIn consideration of the better ypT0-2 downstaging rate, less severe toxicities, and no need for indwelling intravenous device on oral capecitabine regimen, the administration of oral capecitabine with RT may be a more favorable option in the neoadjuvant treatment for LARC.
