A Multi-center, Prospective, Observational Study to Assess the Treatment Patterns and Prognosis of Second and Later-line Palliative Chemotherapy in Patients With Metastatic Colorectal Cancer Who Failed First-line Palliative Chemotherapy
This study aims to comprehensively identify the various treatment patterns of second- or subsequent-line palliative chemotherapy used in patients with metastatic colorectal cancer who have experienced failure of first-line palliative chemotherapy and to evaluate the prognosis of each treatment.
• Patients who have signed the informed consent after receiving information about the purpose and method of this study.
• Patients with histologically and radiologically confirmed metastatic colorectal cancer (colorectal cancer) who have evaluable (measurable) lesions.
• Patients scheduled to receive their first second-line palliative chemotherapy following failure of first-line palliative chemotherapy (including those who relapse during or within 6 months after completion of postoperative adjuvant therapy, necessitating palliative chemotherapy).
• Patients who understand the research, are cooperative in the research process, and are deemed capable of participating until the completion date.
