Burden of illness in second-line colorectal cancer: A systematic literature review.

e14061 Background: Colorectal cancer (CRC) is the third and second most common cancer in males and females, respectively, worldwide. Based on cases diagnosed in 2008, the age-adjusted incidence rate of CRC was 47.2/100,000/year in the US. Approximately 15-25% of all new cases are diagnosed with metastases and half of all cases result in metastases, representing an increased health and economic burden.

No information on the number of patients treated for second-line mCRC was found. Estimate...
