Colorectal cancer (CRC) is the third most common cause of cancer mortality in adults in the United States. With improved population-based screening allowing removal of premalignant polyps, CRC incidence in adults older than 50 years has decreased since the 1990s but has been increasing by 1 to 2 annually since the 1990s in adults younger than 50 years (early onset EO-CRC). Patients with EO-CRC present with more advanced stages of disease compared with older patients (63 vs 49, respectivley). Although there is no universal definition of oligometastatic disease, it is generally used to refer to potentially resectable CRC. Complete resection of both primary and meta-static disease in CRC is associated with improved survival and potential cure, so it is especially important to evaluate outcomes of patients with EO-CRC who present with oligometastatic disease. The aim of this review is to determine the outcomes of oligometastatic disease in the EO-CRC population.
