Overview
Historical Perspective
Discovery
- Appendix cancer was first described in the published literature by Sir George Thos. Beatson, an English surgeon, in 1913.[1]
Landmark Events in the Development of Treatment Strategies
- Genetic studies revolutionized cancer treatment; appendix cancer is not an exception.
- Traditionally appandiceal cancers were approached the same as colorectal cancers. Recent genetic studies demonstrated that appendiceal tumors are clearly differ from colorectal cancers.[2]
- Presence of mutated TP53 and APC genes were significantly lower in appendiceal cancers compared to colorectal cancers.
- It has been shown that mutation profiles are associated with the patients’ prognosis. [3]
- Mutations in the TP53 significantly decrease life expectancy in patients with appendix cancer.
- Regardless of tumor grade, Tp 53 mutations were associated with poorer outcomes.
- Patients with GNAS mutations had a life expectancy of 10 years after diagnosis.
- Appendiceal tumors with GNAS mutations rarely develop into high-grade tumors.
Famous Cases
The following are a few famous cases of appendix cancer:
- Celebrated actress, Audrey Hepburn was the most famous victims of appendix cancer, she passed away in 1993.[4]
- Stuart Scott, ESPN sportscast anchor was diagnosed with appendix cancer in 2007 and died 8 years later in 2015.[5]
