| Summary: | Background: Colorectal cancer (CRC) with subsequent bone metastasis is associated with a poor prognosis compared with patients who do not develop bone metastasis. However, metastasis in bone is rare, contrasted with more common locations such as the liver and lungs. As a result, the treatment methods targeting CRC bone lesions are limited. This review aims to compile information regarding current and potential medical and surgical treatment methods for colorectal cancer with specific regard to bone metastasis. Methods: A computer-based literature review of animal- and human-based studies was conducted using multiple database searches. Case reports were excluded. Results: Preliminary findings demonstrate that treatments specifically targeting bone metastasis due to colorectal cancer are categorized by local vs. systemic treatment. The primary goals are the alleviation of skeletal-related events and improvement in quality of life. Current options include: chemotherapy, radiation, monoclonal antibodies, and surgery. Emerging options include intratumoral mellitin, MRgFUS, and bone microenvironment targeting. Conclusion: Treatment of CRC metastasis to bone is necessary to slow down metastatic progression, alleviate symptoms, and improve quality of life. With a possible rise in bone metastasis due to increased overall CRC survival rates, more clinical trials should be performed to address this growing concern.
