Abstract:
Colorectal cancer (CRC) is the third most common cancer and is associated with a poor prognosis. The mutation profile and related involved pathways of CRC have been, in broad terms, analyzed. The main current therapeutic approaches have been comprehensively reviewed here, and future possible therapeu-tic options and related technologies have been perspectively presented. The complex scenario represented by the multiple-level resistance mechanism in the epidermal growth factor receptor (EGFR) pathway, including mutations in KRAS, NRAS, and BRAF V600E, is discussed. Examples of engineered therapeutic approaches from the literature along with a drug combination tested in clinical trials are discussed. The encouraging results observed with the latter combination (the BEACON clinical trial), totally free from chemotherapy, prompted the authors to imagine a future possible nanotechnology-assisted therapeutic approach for bypassing multiple-level resistance mechanisms, hopefully allowing, in principle, a complete biological cancer remission.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
