Multi drug resistance in Colorectal Cancer- approaches to overcome, advancements and future success

Abstract

A significant obstacle to treating cancer is multidrug resistance (MDR), which is the capacity of cancerous cells to develop resistance to both traditional and cutting-edge chemotherapeutic treatments. Following the initial discovery that cellular pumps reliant on ATP were the root of chemotherapy resistance, more research has revealed the involvement of additional mechanisms, including increased drug metabolism, reduced drug entry, and compromised apoptotic pathways. Numerous projects have focused on MDR, and innumerable research has been conducted to better understand MDR and develop methods to mitigate its consequences. Multidrug resistance (MDR) is a key challenge in treating cancer. 90% of cancer-related fatalities are brought on by tumor metastasis and recurrence, which is possible with MDR. Drug resistance in cancerous cells is influenced by diverse internal and extrinsic variables, including genetic and epigenetic changes, drug efflux systems, DNA repair mechanisms, apoptosis, and autophagy. In this review paper, we list the potential hazards associated with cancer therapy in general, primarily multidrug resistance developing a theory for colorectal cancer in particular. We discussed the unique instance of multidrug resistance in colorectal cancer in malignancies generally and 5-fluorouracil, curcumin, and lipids as viable therapy options for the condition. The use of nanotechnology (mainly nanoparticles) has facilitated better in vitro as well as in vivo efficacy during preclinical phases, summarized below, allowing for a more thorough investigation of colorectal cancers and pancreatic carcinomas with their translation to following clinical trials.
