    Study Notes

    Cervical Cancer Overview

    • 13,000 cases of cervical cancer are diagnosed annually, resulting in over 4,000 deaths.
    • Women aged 40-49 years have the highest incidence of cervical cancer, with 14 cases per 100,000 women per year.
    • 40% of women are older than 40 years at diagnosis.

    Pathogenesis

    • HPV is detected in 99.7% of squamous cell carcinomas and adenocarcinomas.
    • There are 15 known oncogenic strains of HPV, with types 16 and 18 involved in 70% of cervical cancer cases.
    • Most sexually active adults will be exposed to HPV, with over 50% of adults 20-24 years old currently infected.
    • The immune system clears the virus within six months in 50% of women and within two years in up to 90% of women.

    Risk Factors for Cervical Cancer

    • Increased exposure to HPV or decreased ability to clear the virus immunologically.
    • Smoking is associated with an increased risk of squamous cell carcinoma, but not adenocarcinoma.
    • Genetic susceptibility to cervical cancer, with several genetic alterations implicated.
    • Use of oral contraceptives for 5-9 years is associated with an increased risk of cervical cancer.

    Staging of Cervical Cancer

    • Cervical cancer is staged clinically before surgery using the International Federation of Gynecology and Obstetrics 2014 guideline.
    • Staging is determined by tumor size, depth of invasion, spread into surrounding tissue, and distant metastases.
    • Cervical cancer is the only gynecologic cancer staged clinically before surgery.

    Prognosis

    • Prognosis is impacted by stage, tumor volume, depth of cervical stromal invasion, metastases, and LVSI.
    • Disease stage and lymph node status are the two most prognostic factors.
    • Adding bevacizumab (Avastin) to combination chemotherapy can improve overall survival in women with recurrent, persistent, or metastatic cervical cancer.
