Summary
Women with vulvar or vaginal cancer have increased risks of developing second cancers, primarily linked to smoking and human papillomavirus infection. Smoking cessation is crucial for follow-up care.
Area of Science:
- Gynecologic Oncology
- Cancer Epidemiology
- Public Health
Background:
- Vaginal and vulvar cancers are rare gynecologic malignancies.
- Understanding the risk of subsequent primary cancers is crucial for patient management and public health strategies.
Purpose of the Study:
- To investigate the incidence of second primary cancers following diagnoses of vaginal and vulvar cancers.
Main Methods:
- A cohort of women diagnosed with in situ or invasive vaginal (n=1349) and vulvar (n=5583) cancers between 1973-1988 was identified from nine population-based cancer registries.
- Follow-up through 1989 was conducted to ascertain the development of subsequent primary cancers.
Main Results:
- Women with vulvar cancer showed increased risks for subsequent cancers (in situ: O/E=1.5; invasive: O/E=1.3).
- Women with invasive vaginal cancer also had an elevated risk (O/E=1.2).
- The majority of these second cancers were associated with smoking (lung, oral, esophageal) or human papillomavirus (HPV) infection (cervical, anal, vulvar, vaginal).
Conclusions:
- Follow-up care for vaginal and vulvar cancer patients should prioritize smoking cessation interventions.
- The findings suggest a potential common etiology, possibly HPV, for cancers of the cervix, vulva, vagina, and anus.
