Research Article: Identification and Validation of Key miRNAs for Colon Cancer Based on miRNA-Gene Integration Analysis

Date Published: 2023-12-05

Abstract:
With nearly million new cases and million deaths worldwide in , colorectal cancer is the third-most common cancer and the second leading cause of cancer-related deaths. According to data from the US Surveillance, Epidemiology and End Results program and the National Program of Cancer Registries program, the incidence of colorectal cancer among people aged to years and young adults under years is increasing by % and % per year, respectively. Among them, colon cancer is nearly one-third more common than rectal cancer. In addition, patients with colon cancer have lower - and -year survival and a worse prognosis than patients with rectal cancer. Colon cancer treatment requires multimodal management, such as surgery, radiotherapy, chemotherapy, immunotherapy, and molecular targeted therapy. Although existing treatment strategies have achieved specific results, obstacles such as limited drug selection, drug resistance, complex anatomical localization, and post-operative recurrence rates have brought colon cancer to the forefront of the research agenda. The initial symptoms of colorectal cancer are atypical, and the early diagnosis rate is relatively low, with more than % of patients already at an advanced stage at the initial diagnosis. Therefore, elucidating the pathogenesis of colon cancer, identifying novel molecular targets, and developing targeted drugs are the critical measures needed to improve the treatment and survival of individuals with this aggressive disease.
