Role of Cellular Biomolecules in Screening, Diagnosis and Treatment of Colorectal Cancer.

Abstract

Prevention is the primary strategy to avoid the occurrence and mortality of colorectal cancer. Generally, the concentrations of tumor markers tested during the diagnosis and believed to assist the detection of disease in the early stages of cancer. Some of the biomarkers are also important during treatment and real-time monitoring of the progress of treatment. We considered a rationale search of key references from the database of peer-reviewed research and review literatures of colorectal cancer. The topic of search was focused on the novel methods and modern techniques of Screening, Diagnosis, and Treatment of colorectal cancer. The screened publications were critically analysed using a deductive content analysis and the matter was put in separate headings and sub headings. It was found that endoscopic examination, early detection, and surgery are some of the common strategies to manage colorectal cancer because late stages are difficult to treat due to the high-cost requirement and fewer chances of survival. As far as chemotherapy is concerned, systemic chemotherapy has been shown to offer the maximum benefit to patients with cancer metastasis. Among different chemotherapy measures, primary colorectal cancer prevention agents involve pharmaceuticals, phytochemicals, and dietary supplements are some of the standard options. In this review article, we have provided a comprehensive analysis of different biomarkers for the detection of colorectal cancer as well as different formulations developed for efficient treatment of the disease. The use of dietary supplements, the combinatorial approach, and nanotechnology-based strategies for colorectal cancer diagnosis and treatment are some of the recent and modern methods of cancer management.
