Risk calculators and risk factors for Cervical cancer natural history, complications and prognosis

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Prognosis depends on the stage of the cancer. With treatment, 80 to 90% of women with stage I cancer and 50 to 65% of those with stage II cancer are alive 5 years after diagnosis. Only 25 to 35% of women with stage III cancer and 15% or fewer of those with stage IV cancer are alive after 5 years.

Complications

  • Some types of cervical cancer do not respond well to treatment.
  • The cancer may come back (recur) after treatment.
  • Women who have treatment to save the uterus have a high risk of the cancer coming back (recurrence).
  • Surgery and radiation can cause problems with sexual, bowel, and bladder function.

Prognosis

The prognosis for patients with cervical cancer is markedly affected by the extent of disease at the time of diagnosis. More than 90% of cervical cancer cases can be detected early through the use of the Pap test and HPV testing.Pap and HPV testing are not performed on approximately 33% of eligible women, which results in a higher-than-expected death rate.

  • Prognostic Factors
  • Clinical stage
  • Clinical stage as a prognostic factor is supplemented by several gross and microscopic pathologic findings in surgically treated patients.
  • Gynecologic Oncology Group identified the following variables that were significant for progression-free interval and survival:
  • Periaortic and pelvic lymph node status.
  • Tumor size
  • Patient age
  • Performance status
  • Bilateral disease
  • Clinical stage
  • Other prognostic factors
  • Other prognostic factors that may affect outcome include the following:
  • Human immunodeficiency virus (HIV) status: Women with HIV have more aggressive and advanced disease and a poorer prognosis.
  • C-myc overexpression: A study of patients with known invasive squamous carcinoma of the cervix found that overexpression of the C-myc oncogene was associated with a poorer prognosis.
  • Number of cells in S phase: The number of cells in S phase may also have prognostic significance in early cervical carcinoma.
  • HPV-18 DNA: HPV-18 DNA has been found to be an independent adverse molecular prognostic factor. Two studies have shown a worse outcome when HPV-18 was identified in cervical cancers of patients undergoing radical hysterectomy and pelvic lymphadenectomy.
  • A polymorphism in the Gamma-glutamyl hydrolase enzyme, which is related to folate metabolism, has been shown to decrease response to cisplatin, and as a result is associated with poorer outcomes.

Average years of potential life lost from cervical cancer are 25.3 (SEER Cancer Statistics Review 1975-2000, National Cancer Institute (NCI)). Approximately 4,600 women were projected to die in 2001 in the US of cervical cancer (DSTD), and the annual incidence was 13,000 in 2002 in the US, as calculated by SEER. Thus the ratio of deaths to incidence is approximatley 35.4%.

5-Year Survival

  • Between 2004 and 2010, the 5-year relative survival of patients with cervical cancer was 69.6 %.[1]
  • When stratified by age, the 5-year relative survival of patients with cervical cancer was 71.9% and 48% for patients <65 and ≥ 65 years of age respectively.[1]
  • The survival of patients with cervical cancer varies with the stage of the disease. Shown below is a table depicting the 5-year relative survival by the stage of cervical cancer:[1]
Stage 5-year relative survival (%), (2004-2010)
All stages 67.9%
Localized 90.9%
Regional 57.4%
Distant 16.1%
Unstaged 54.3%
  • Shown below is an image depicting the 5-year conditional relative survival (probability of surviving in the next 5-years given the cohort has already survived 0, 1, 3 years) between 1998 and 2010 of cervical cancer by stage at diagnosis according to SEER. These graphs are adapted from SEER: The Surveillance, Epidemiology, and End Results Program of the National Cancer Institute.[1]
