Angiogenesis plays an important role in the progression of colorectal cancer (CRC). Studies have indicated vascular endothelial growth factor (VEGF) is the predominant angiogenic factor. Cyclin D1 (CCND1) induces production of VEGF and is required for migration of blood vessels. Our aim was to determine the roles of CCND1 and VEGF overexpression in CRC patients. ⋯ Co-existence of CCND1 and VEGF overexpression would potentially assist in TNM staging systems to predict the prognosis of these patients who would benefit from intensive follow-up and therapeutic programs.

Cancer is one of the leading causes of death worldwide. The global cancer burden (GCB) is expected to rise significantly and will disproportionately affect the less developed world (LDW). The aim of this review is to analyze the trends in GCB and describe the types, estimates, and causes of new cancer cases. The challenges and strategies associated with tackling this rising GCB are described in which surgeons can play a vital role.
