**3. Multidisciplinary CRC: introduce for contents**

In the clinical sense, a multidisciplinary approach for treating CRC means that can support the providing seamless coordination of treatment and has important goals in achieving improved outcomes crucially [5]. As it can be inferred from the foregoing paragraph, however, this book is not intended to emphasize an integrated approach that takes advantage of the optimal options for CRC treatment, including surgery, chemotherapy, and radiation therapy. It contains a variety of unique academic texts on the prevention, prognostic, and therapeutic application for understanding the pathogenesis and progression of CRC. For providing preventative or prolific factors, one chapter provides an overview regarding the role of diet, alcoholic beverages, vitamins, fatness, physical activity, and dietary supplements. Another chapter explains the pathogenesis of CRC, which can be identified as the recent advances in molecular biology, through the risk factors, and also contains contents providing the applicability to new drug development for targeting advanced CRC. In addition, a chapter for therapeutics introduces a method with photodynamic therapy, describing the introduction of unconventional CRC therapy and known efficacy and potential for recent developments. Another chapter includes an introduction to the relationship between immune scores and microbiomes in prognosis in CRC patients by using a scoring system that analyzes the consequences of the immune balance beyond the concept of prognostic prediction through biological markers. In the other chapter, a comparison was made in terms of currently available systemic treatment options, efficacy, and safety profiles for understanding the patients with advanced metastatic colorectal cancer that has remained a challenge for oncologists.
