Primary Outcomes (1)

  • Age

    colorectal cancer (CRC) patients younger than 35 years and comparing them against CRC patients older than 35 years of age.

    20 years

Study Arms (1)

colorectal cancer (CRC) patients younger than 35

The hypothesis is that patients younger than 35 years of age with CRC will present with more advanced disease at diagnosis but will have longer survival overall through more aggressive therapy.

Other: Colorectal cancer

Interventions

CRC is a disease that is often associated with older adults (\<50 years). CRC remains the second most common cause of cancer death in males and the third most common cancer death in women. Despite this, CRC incidence has steadily declined in older adults; however, there is a concerning rise of incidence of colorectal cancer in young patients. The incidence of CRC in men and women under the age of 50 steadily increased 2.1 percent per year from 1992 through 2012.
