Abstract
Future options for the management of stage IV colorectal cancer are primarily focused
on personalized and directed therapies. Interventions include precision cancer medicine,
utilizing nanocarrier platforms for directed chemotherapy, palliative pressurized
intraperitoneal aerosol chemotherapy (PIPAC), adjunctive oncolytic virotherapy, and
radioembolization techniques. Comprehensive genetic profiling provides specific tumor-directed
therapy based on individual genetics. Biomimetic magnetic nanoparticles as chemotherapy
delivery systems may reduce systemic side effects of traditional chemotherapy by targeting
tumor cells and sparing healthy cells. PIPAC is a newly emerging option for patients
with peritoneal metastasis from colorectal cancer and is now being used internationally,
showing promising results as a palliative therapy for colorectal cancer. Oncolytic
virotherapy is another emerging potential treatment option, especially when combined
with standard chemotherapy and/or radiation, as well as immunotherapy. And finally,
radioembolization with yttrium-90 (90Y) microspheres has shown some success in treating patients with unresectable liver
metastasis from colorectal cancer via selective arterial injection.
