TEST BANK
True/False Questions
- Epidemiologic features of vaginal, vulvar, and anal cancer are similar to cervical cancer since all are etiologically linked to infection of the respective tissues by oncogenic strains of human papilloma virus (HPV).
- Worldwide in 2018, cancers of the vagina, vulva, and anus were diagnosed in 90,180 women and caused 32,795 deaths.
- Anal cancer also afflicted 20,196 men in 2018, causing an additional 9,618 deaths in the male population.
- In contrast to cervical cancer, malignancies of the vagina and vulva are relatively rare and account for less than 0.5% of all female cancers and less than 5% of malignancies of the female genital tract.
- Most vaginal, vulvar, and anal malignancies (90-95%) are squamous cell carcinomas that arise from the stratified epithelium that covers these anatomic sites.
- The Population Attributable Fraction is an estimate of the proportion of cases of a specific disease (cancer) that could theoretically be avoided if exposure to a specific risk factor (such as HPV infection) was eliminated.
- Approximately two-thirds of cases of vaginal, vulvar, and anal cancer are attributable to infection by oncogenic strains of HPV.
- Co-infection by HIV has no effect on the development of HPV-related malignancies of the anogenital tract.
- Development of clear cell adenocarcinomas of the vagina in young girls has been causally linked to in utero exposure to diethylstilbestrol (DES).
- Cigarette smoking is not a risk factor for vaginal, vulvar, or anal cancer.
