CTCs detection by CellSearch is a highly reproducible method that correlates with stage but not with other clinical and morphological variables in patients with colorectal cancer. Colon cancer tumor cells are detectable in all stages. Further studies are warranted.

CTC detection was not associated with worse DFS and OS in patients with stage III CRC. Given the scarcity of CTC in these patients, it is likely that CTC determined by CellSearch system does not have a prognostic role in this setting. However, a longer follow-up is needed.

Serum FGF23 concentrations remain increased in long-term kidney graft recipients, even in the early stages of CKD. It remains to be seen whether measures aimed at reducing serum levels of PTH and phosphate and/or corticosteroid doses might help to lower serum FGF23 and whether this will improve kidney recipient outcomes.

There is a subgroup of carcinomas which develop via the MSI pathway that carry an alteration of the BRAF gene. This alteration confers a poorer outcome on these patients within the total group of patients with MSI who have a better prognosis. This hypothesis should be further investigated in a larger study population due to the low incidence of BRAF mutations in colorectal cancer.
