Abstract

The objective of this study was to improve the immediate and long-term results of combined treatment of patients with locally advanced rectal cancer. The study included 128 patients with morphologically confirmed diagnosis and clinical stage cT3/T4 and N-/N+, treated from 1998 to 2009. The comparison group had 64 patients, combined treatment included prolonged preoperative radiotherapy 4 Gy and 40 Gy, surgery was performed after 4 weeks. In the study group - also 64 patients - combined treatment consisted of preoperative chemoradiotherapy (continuous a-120 hour infusion of 5-fluorouracil at a dose of 500 mg/m 2 in the first and last week of radiotherapy in 2 Gy to 50 Gy), surgery was performed through 6 weeks after chemoradiotherapy. Excision of the primary tumor was performed in 40 (62.5 %) patients in the control group and in 53 (82.8 %) patients in the study group. Wherein R-0 resections were performed in 32 (67 %) patients and in 41 (73 %), and R-1 resections - in 1 (2 %) patients, and 7 (13 %) patients in the control and study groups respectively. A. 5-year survival rate was 43,6 ± 7,2 % control and 62,7 ± 5,1 % in the study group.
