“…The addition of irinotecan to 5-FU/FA, irrespective of regimen, conferred a significant clinical benefit, in terms of RR (35 vs 22, 39 vs 21, 54 vs 32%), progression-free survival (PFS: 6.7 vs 4.4, 7.0 vs 4.3, 8.5 vs 6.4 months) and overall survival (17.4 vs 14.1, 14.8 vs 12.6, 20.1 vs 16.9 months) compared with the corresponding 5-FU/ FA regimen alone (respectively for Douillard et al, 2000;Saltz et al, 2000;Köhne et al, 2005). Also, although the more recent phase III study of Köhne et al, failed to demonstrate a statistically significant improvement in overall survival, the trend of 43 months increase led to one of the longest median overall survival times, to date, in this clinical setting.…”
