Is the Effect of Tumor Localization on Prognosis Compatible with Real-life Data in Metastatic Colon Cancer? Single-Center Experience: A Retrospective Analysis.

Although tumors located in the right colon have been considered to be worse in terms of progression-free and overall survival in clinical trials, the results of this study showed that in daily practice, there was no difference between left and right colon localized tumors in progression-free and overall survival. Further, in k-ras wild-type colon cancers, tumor localization predicts the treatment response. This study is important with the presentation of real-life data and compatibility with the data of the studies to daily life.
