Abstract 111P
Background
In present time, neoadjuvant chemoradiotherapy for distal rectal cancer is part of clinical guidelines in Europe and the USA. According to the literature, there are no unified standards for upper rectal cancer.
Methods
The study included data from patients over 18 years old, with histologically proven adenocarcinoma with TNM stage T2-4aN0-2M0 and tumour location in the upper part of the rectum (10-15 sm). In the main group (A), preoperative chemoradiotherapy was performed: short-course radiotherapy (5x5 Gy), with capecitabine 2000 mg/m2 × 2 times for 14 days, followed by surgical treatment. In the control group (B) only surgical treatment was performed - partial or total mesorectumectomy.
Results
From January 2004 to December 2014, 226 (99.6%) underwent surgical treatment. The incidence of postoperative complications byClavien-Dindo scale was:group A - 17 (16.5%) and group B - 11 (8.9%). Local recurrences in group A occurred in 1 patient (1.2%), in group B - in 3 (2.5%) patients (p = 0.413). Distant metastases in group A developed in 10 (10.2%) patients, in group B -15 (12.6%) patients (p = 0.581). Overall survival was in group A - 90.6%, recurrence-free - 89.6%; in group B - 82.8% and 81.9%, respectively (p = 0.46). Multivariate analysis showed that the affected regional lymph nodes were the main predictor of poor prognosis (p = 0.001, OR = 0.094, CI = 0.035-0.250) and significantly reduced the 5-year disease-free survival rate (p = 0.001, OR = 4.213, CI = 2.010-8.830).
Conclusions
The results of the study showed that neoadjuvant chemoradiotherapy in comparison with the surgical method does not have an advantage for patients with upper rectum cancer.
