Overview

Epidemiology and Demographics

  • Epidemiology of appendix cancer should be discussed with respect to the histological characteristics.
  • Prevalence, risk factors, age distribution as well as prognosis is different in two major types of apendiceal cancers.
  • According to the SEER database, Adenocarcinoma accountede for 58% of appendiceal tumours.
  • Carcinoid tumors comprise 50-77% of appendiceal malignancies.

Incidence

  • The incidence of carcinoid tumor of appendix is approximately 0.075 per 100,000 individuals worldwide.

Prevalence

  • The estimated prevalence of appendix cancer is approximately 0.12 cases per 100,000 individuals in the United States.[1]
  • The estimated prevalence of adenocarcinoma of the appendix is 0.2 cases per 100,000 individuals worldwide;[1] on the other hand,
  • Appendiceal neoplasms account for approximately 0.4% of gastrointestinal tumors.


Case-fatality rate/Mortality rate

  • In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
  • The case-fatality rate/mortality rate of [disease name] is approximately [number range].

Age

  • The incidence of apendix cancer increases with age; meanwhile, patients with carcinoid tumors are generally younger than patients with adenocarcinoma.
  • The median age at diagnosis is 65 years for Adenocarcinoma, compared to t 32-43 years (range, 6 to 80 years) for Carcinoid tumors.
    • Patients with Tubular carcinoids are significantly younger than the patients with goblet cell carcinoids.

Race

  • There is no racial predilection to [disease name].
  • [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].

Gender

  • Generally appendiceal cancers affects men and women equally.
  • While in adenocarcinoma there is a male dominant pattern of prevalence, females are more commonly affected by appendiceal carcinoids than men, This might be because of high incidental appendicectomies in women. Nevertheless, in the SEER database, the male to female ratio is approximately 1 to 1.
