“…The pCR rate ranged from 7% to 31% in most of the previously reported studies with capecitabine and RT, 14,[21][22][23][24][25][26][27][28][29][30] and FOLFOX and radiation therapy and 5-FU and radiation therapy up to a level of 18-25%. [31][32][33][34] The pCR rate in the current study (13.6%) is comparable to those found by Kim 14 The higher figures in these studies in comparison to the present study may be due to a more favorable distribution of the T stage, 22 the use of a radiation boost to the tumor, or the use of leucovorine in addition to capecitabine. 14 These discordant results may be due to differences in staging of the primary tumor; as we know, EUS seems to provide more accurate staging for mobile T1 and T2 lesions, whereas MRI seems to be superior for fixed, more locally advanced disease.…”
