Colorectal cancer in elderly patients: A single-center experience.

As the current population ages and more people live longer, the incidence of cancer in elderly patients (pts) is expected to rise. Several studies have shown that cancer treatment is beneficial for elderly pts in adjuvant and palliative setting. However, elderly pts with cancer have been underrepresented in clinical trials and there is little literature on this pts group. We now want to present our own experience in the treatment of elderly pts with colorectal cancer (CRC). Methods: Since July 2006 all pts with new diagnosed CRC were recorded in a tumor registry at the Klinikum Wels- Grieskirchen.
