Oral Adjuvant Therapy for Colorectal Cancer: Recent Developments and Future Targets

Colorectal cancer is considered the third most frequent malignant neoplasm occurring in both men and women worldwide. Most approaches that have been used to fight and treat this type of malignancy are either invasive or nonselective. Noninvasive therapy using oral route can increase patient compliance and reduce treatment costs. Innovative measures such as use of nanotechnology and theranostic systems have been initiated in the oral therapy, which has been proven to be greatly advantageous in decreasing side effects, improving detection and diagnoses. This manuscript investigates recent innovative and novel therapeutic approaches through oral route and potential targets in the treatment of colorectal cancer.
