Overview
Epidemiology and Demographics
- Epidemiology of appendix cancer should be discussed with respect to the major histological characteristics of tumors.
- Prevalence, risk factors, age distribution as well as prognosis are different in two major types of apendiceal cancers.[1]
- According to the SEER database, adenocarcinoma accounted for 58% of appendiceal tumors. [2]
- Carcinoid tumors comprise 50-77% of appendiceal malignancies.[3]
Incidence
- The incidence of carcinoid tumor of appendix is approximately 0.075 per 100,000 individuals worldwide.[4]
- The incidence of adenocarcinoma of the appendix is approximately 0.2 per 100,000 individuals worldwide.[5]
Prevalence
- Appendiceal neoplasms account for approximately 0.4% of gastrointestinal tumors.
- The estimated prevalence of appendix cancer is approximately 0.12 cases per 100,000 individuals in the United States.[6]
- The estimated prevalence of adenocarcinoma of the appendix is 0.2 cases per 100,000 individuals worldwide;[6] on the other hand,?????????
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].
- ???????????there are for acute diseases generally????
- The 5-year survival
- Appendiceal carcinoid tumors
- 94% localized disease
- 85% regional disease
- 34% distant metastases
- goblet cell 12.5%
- Tubular tumors are benign clinically
- Adenocarcinoma
- localized 95%
- Distant metastasis 0%
- Mucinous
- localized 80%
- Distant metastasis 51%
- Poor prognostic factors for adenocarcinoma are as follows: advanced stage, high grade, nonmucinous histology, spread of the tumor beyond the left lower quadrant, presence of malignant cells outside of the visceral peritoneum of the appendix .
Age
- The incidence of apendix cancer increases with age; meanwhile, patients with carcinoid tumors are generally younger than their adenocarcinoma counterparts.
- The median age at diagnosis is 65 years for adenocarcinoma, compared to t 32-43 years (range, 6 to 80 years) for carcinoid tumors.[7][4]
- The patients with Tubular carcinoids are significantly younger than the patients with goblet cell carcinoids.[8]
Race
- There is no racial predilection to appendiceal cancers.[1]
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; [4][5]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.[1][7][5]
