Recent updates on innovative approaches to overcome drug resistance for better outcomes in cancer.

Abstract

The multi-dimensional challenge of drug resistance is one of the pivotal hindrances for cancer chemotherapy. A reductive approach to define and distinguish the main aspects of drug resistance, such as tumor growth kinetics about tumor micro-environment (tumor multifariousness), therapeutic pressure, physical barricades, irreversible genetic mutation, as well as role of the immune system, are the main causes of failure in cancer therapy are presented systematically. We are focusing on general approaches to reduce drug resistance: earlier diagnosis of tumors allowing for cancer halting; dynamic surveillance throughout treatment; the adding of new therapeutic strategies and improve pharmacodynamics precepts resulting in profound effects; and identification of cancerous cells repositories using high-throughput monitoring, as well as the interoperability of clinical- gene mapping statics are described in detail. These strategies could be potentially constructed for any tumor at any precise moment and used to guide therapy selection. Chemotherapeutic agents results in mild improved survival in clinical trials owing to several pathophysiologic obstacles, such as intra-tumoral dispersion, invasion & intra-cellular transportation. This review highlights recent advancements in developing new therapeutic innovations to combat drug resistance in cancer therapy by overcoming various barricades in the tumor microenvironment.
