Study Notes

Carcinoma of the Cervix

The oral contraceptive pill has a slightly increased risk of cervical cancer, influenced by other risk factors.
Screening involves Pap smears, which are recommended for HIV-negative women every 10 years starting from age 30, and for HIV-positive women every 6 months for 3 years, and then yearly if no abnormalities are found.

Presentation of Carcinoma of the Cervix

Early symptoms: abnormal vaginal bleeding, post-coital bleeding, and abnormal vaginal discharge.
Late symptoms: pain and weight loss.

Diagnosis of Carcinoma of the Cervix

Colposcopy may be necessary to detect very early lesions that are invisible to the naked eye.
High-risk types of HPV (16, 18, 31, 33, 35, 39, 45, 51, 56, 58, and 66) are associated with carcinoma of the cervix.

HPV and Cervical Cancer

HPV is predominantly sexually transmitted and survives inside epithelial cells.
When host factors are favorable, HPV DNA integrates into host DNA, leading to dysplastic cells.
80% of sexually active women will be exposed to HPV in their teens and early twenties, but most infections will disappear spontaneously.
Only women with persistent high-risk HPV infection after the age of 30 are at risk for developing cervical cancer.

Risk Factors for HPV Exposure

Coital factors: early sexual debut, coitus with multiple partners, and Chlamydia Trachomatis infection.
Other male factors: possible presence of oncogenic proteins in semen.
Racial and cultural factors: women of low socio-economic groups have a higher incidence of cervical carcinoma.
Other factors: smoking cigarettes is associated with a two-fold increase in the risk of developing cervical carcinoma.

Premalignant Lesions of the Cervix

Cervical Intraepithelial Neoplasia (CIN) is a recognized precursor of invasive carcinoma of the cervix.
CIN has three types: CIN 1, CIN 2, and CIN 3, based on the degree of epithelial involvement.
The Bethesda system is used for cytology reporting, with terms such as Squamous Intraepithelial Lesion (SIL) low grade and SIL high grade.
