Abstract
Metastatic colorectal cancer is the 3rd most prevalent cancer globally and ranks 2nd in terms of cancer-related deaths. In Egypt, colon and rectal cancers were the 9th and 18th most common malignancies and the 11th and 16th most prevalent cause of cancer-related mortality in the country, respectively. In the management of mCRC, there is need to determine predictive and prognostic factors that are likely to impact the tumor response and survival outcomes of systemic treatment. This is particularly true as the 1st and 2nd systemic lines of treatment are still the most effective treatment modalities available to control the illness. Real-world studies show that patients derive maximal benefit from 1st and 2nd line therapies as a later line of treatment do not provide a similar level of benefits. They must thus be optimized. AIM OF THE STUDY: The aim of this study was to identify the factors affecting tumor response in metastatic colorectal cancer patients to first line and second line treatment. PATIENTS AND METHODOLOGY: A retrospective cohort study investigating the factors affecting tumor response in mCRC patients to 1st and 2nd line treatment with a sample size of 110 patients managed for mCRC between January 2019 and December 2023. The study extracted information on demographic data, clinical, pathological, laboratory data, and molecular characteristics. The results were statistically analyzed with clinical outcomes.
