AI Article Synopsis
Article Abstract
Deaths caused by colorectal cancer (CRC) are among the leading causes of cancer-related death in the United States and around the world. Approximately 150,000 Americans are diagnosed with CRC each year and around 50,000 will die from it. Mutations in many key genes have been identified that are important to the pathogenesis of CRC. Among the genes mutated in CRC, RAS and RAF mutations are common events. Both RAS and RAF are critical mediators of the mitogen-activated protein kinase (MAPK) pathway that is involved in regulating cellular homeostasis, including proliferation, survival, and differentiation. In this review, we provide a historical perspective and update on RAS/RAF mutations as related to colorectal cancer. Additionally, we will review recent mouse models of RAS and RAF mutations that have an impact on CRC research.

Aim: Colorectal cancer (CRC) ranks as the second most diagnosed and third most deadly cancer worldwide. Despite advances in early diagnosis and treatment, CRC remains a leading cause of cancer-related deaths. Up to 30% of CRC patients are diagnosed during emergency department visits, leading to surgical procedures that may not adhere to oncological principles due to complications like obstruction, bleeding, or perforation.

Aim: Colorectal cancer (CRC) primarily arises from a combination of genetic, environmental, and dietary factors. Compared to traditional open surgery, minimally invasive laparoscopic surgery offers several advantages in managing CRC. This study investigates the factors influencing dynamic intestinal obstruction following laparoscopic colorectal radical surgery.

Aim: This research aimed to evaluate the long-term survival rates and relapse-free status of colorectal cancer (CRC) patients with peritoneal metastases who underwent cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC). The data are expected to provide valuable insights for determining therapeutic options for these patients.

Understanding the molecular signaling pathways of colorectal cancer (CRC) can be accepted as the first step in treatment strategy. Permanent mTOR signaling activation stimulates the CRC process via various biological processes. It supplies the survival of CRC stem cells, tumorigenesis, morbidity, and decreased response to drugs in CRC pathogenesis.
