Incidence:
global public health issue
450,000 – 500,000 women diagnosed each
year worldwide
In developing countries, it is the most
common cause of cancer death
340,000 deaths in 1985
United States Incidence
15,000 women diagnosed annually
4,800 annual deaths
Mortality Rates
• <2/100,000: Finland, France, Greece,
Israel, Japan, Korea, Spain, Thailand
• 2.7/100,000: USA
• 12-15.9/100,000: Chile, Costa Rica,
Mexico
Lifetime risk of developing
cervical cancer
5% - South America
0.7% - USA
Cervical CA Risk Factors
•
•
•
•
•
•
•
Early age of intercourse
Number of sexual partners
Smoking
Lower socioeconomic status
High-risk male partner
Other sexually transmitted diseases
Up to 70% of the U.S. population is infected with
HPV
Screening Guidelines for the Early
Detection of Cervical Cancer,
American Cancer Society 2003
• Screening should begin approximately three years after a women
begins having vaginal intercourse, but no later than 21 years of
age.
• Screening should be done every year with regular Pap tests or
every two years using liquid-based tests.
• At or after age 30, women who have had three normal test results
in a row may get screened every 2-3 years. However, doctors may
suggest a woman get screened more if she has certain risk factors,
such as HIV infection or a weakened immune system.
• Women 70 and older who have had three or more consecutive Pap
tests in the last ten years may choose to stop cervical cancer
screening.
• Screening after a total hysterectomy (with removal of the cervix) is
not necessary unless the surgery was done as a treatment for
cervical cancer.
American Cancer Society. Cancer Facts & Figures. 2004. Atlanta, GA; 2005
Pap Smear
• Single Pap false negative rate is 20%.
• The latency period from dysplasia to
cancer of the cervix is variable.
• 50% of women with cervical cancer have
never had a Pap smear.
• 25% of cases and 41% of deaths occur in
women 65 years of age or older.

Histology
Squamous
85-90%
Adenocarcinoma
10-15%
Lymphoma

Melanoma
Route of Spread
Cervical cancer spreads by direct
invasion or by lymphatic spread
Vascular spread is rare

•
•
•
•
•
Physical exam
Cervical biopsies
Chest x-ray
IVP (Ct scan)
Barium enema, cystoscopy, proctoscopy
Surgical staging
Staging
Stage I – confined to the cervix
IA1 – <3mm depth of invasion
IA2 – stromal invasion 3-5mm in depth
or <7 mm in width
IB1- tumor < 4 cm
IB2 - tumor > 4 cm in diameter
Stage II – extension beyond cervix
IIA – upper 2/3 of vagina
IIB – Parametrial involvement
Staging
Stage III
IIIA – lower 1/3 of vagina
IIIB – extension to pelvic sidewall or
hydronephrosis

Vulvar Cancer
• 3870 new cases 2005
• 870 deaths
• Approximately 5% of Gynecologic
Cancers

Vulvar Cancer
•
•
•
•
85% Squamous Cell Carcinoma
5% Melanoma
2% Sarcoma
8% Others
Vulvar Cancer
• Biphasic Distribution
• Average Age 70 years
• 20% in patients UNDER 40 and appears to
be increasing
Vulvar Cancer Etiology
• Chronic inflammatory conditions and
vulvar dystrophies are implicated in older
patients
• Syphilis and lymphogranuloma venereum
and granuloma inguinal
• HPV in younger patients
• Tobacco
Vulvar Cancer
• Paget’s Disease of Vulva
– 10% will be invasive
– 4-8% association with underlying
Adenocarcinoma of the vulva
Symptoms
• Most patients are treated for “other”
conditions
• 12 month or greater time from symptoms to
diagnosis

Recurrence
• Local Recurrence in Vulva
– Reexcision or radiation and good prognosis if
not in original site of tumor
– Poor prognosis if in original site
Recurrence
• Distal or Metastatic
– Very poor prognosis, active agents include
Cisplatin, mitomycin C, bleomycin,
methotrexate and cyclophosphamide
Melanoma
• 5% of Vulvar Cancers
• Not UV related
• Commonly periclitoral or labia minora
Melanoma
• Microstaged by one of 3 criteria
– Clark’s Level
– Chung’s Level
– Breslow
Melanoma Treatment
• Wide local or Wide Radical excision with
bilateral groin dissection
• Interferon Alpha 2-b
Vaginal Carcinoma
• 2140 new cases projected 2005
