Abstract

Major advances in cancer research in the last two decades have provided us with a better understanding of the dynamics of the cancer cell and its microenvironment. This has consequently led to the development of new therapies and treatment strategies either targeting the cancer cell or the tumor microenvironment. In this review we will discuss the major existing and promising future treatment approaches in medical oncology. Therapies targeting the cancer cell include hormonal therapies, small molecules, and monoclonal antibodies. They are used mostly in the advanced disease setting. Strategies developed more recently are antibody drug conjugates (trastuzumab emtansine and radioimmunotherapy) and oncolytic viruses. Molecular therapies targeting the tumor microenvironment include angiogenesis inhibitors and the new agents and approaches that interfere with the immune system (immune checkpoint inhibitors and adoptive cell therapy). The development of resistance (primary and acquired) to targeted therapies is unfortunately a common phenomenon that can be overcome or delayed using multiple strategies like the use of second- or third-generation molecular therapies targeting the emerging resistant mutations or genetic abnormalities, m...Continue Reading

Cell Checkpoints & Regulators

Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.

Angiogenesis Inhibitors to Treat Cancer

Cancer treatments including angiogenesis inhibitors prevent tumor cells from receiving nutrients and oxygen. Here is the latest research on angiogenesis inhibitors for the treatment of cancer.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
