Cervical Cancer Screening

Overview

Cervical cancer Cervical cancer Cervical cancer, or invasive cervical carcinoma (ICC), is the 3rd most common cancer in women in the world, with > 50% of the cases being fatal. In the United States, ICC is the 13th most common cancer and the cause of < 3% of all cancer deaths due to the slow progression of precursor lesions and, more importantly, effective cancer screening. Cervical Cancer

• Cancer of the uterine cervix Cervix The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Externally, the cervix is lined by stratified squamous cells; however, the cervical canal is lined by columnar epithelium. Uterus, Cervix, and Fallopian Tubes: Anatomy
• Major histologic types:
  • Squamous cell carcinoma Squamous cell carcinoma Cutaneous squamous cell carcinoma (cSCC) is caused by malignant proliferation of atypical keratinocytes. This condition is the 2nd most common skin malignancy and usually affects sun-exposed areas of fair-skinned patients. The cancer presents as a firm, erythematous, keratotic plaque or papule. Squamous Cell Carcinoma (SCC): approximately 80% of cervical cancers
  • Adenocarcinoma: 15%
  • Adenosquamous carcinoma: 3%–5%
• Associated with human papillomavirus Human papillomavirus Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV) ( HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact.

Screening Rationale

• Screening Screening Preoperative Care is recommended because:
  • Women 21‒65 years of age are at risk for cervical cancer Cervical cancer Cervical cancer, or invasive cervical carcinoma (ICC), is the 3rd most common cancer in women in the world, with > 50% of the cases being fatal. In the United States, ICC is the 13th most common cancer and the cause of < 3% of all cancer deaths due to the slow progression of precursor lesions and, more importantly, effective cancer screening. Cervical Cancer due to potential exposure to high-risk human papillomavirus Human papillomavirus Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV) (hrHPV) through sexual intercourse.
  • A 75% decline in the incidence Incidence The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from prevalence, which refers to all cases in the population at a given time. Measures of Disease Frequency and mortality Mortality All deaths reported in a given population. Measures of Health Status of cervical cancer Cervical cancer Cervical cancer, or invasive cervical carcinoma (ICC), is the 3rd most common cancer in women in the world, with > 50% of the cases being fatal. In the United States, ICC is the 13th most common cancer and the cause of < 3% of all cancer deaths due to the slow progression of precursor lesions and, more importantly, effective cancer screening. Cervical Cancer occurred in the past 50 years due to screening Screening Preoperative Care.

  • Cervical cancer Cervical cancer Cervical cancer, or invasive cervical carcinoma (ICC), is the 3rd most common cancer in women in the world, with > 50% of the cases being fatal. In the United States, ICC is the 13th most common cancer and the cause of < 3% of all cancer deaths due to the slow progression of precursor lesions and, more importantly, effective cancer screening. Cervical Cancer usually does not cause symptoms.
• Screening Screening Preoperative Care is not recommended earlier than age 21 because:
  • Cancerous and precancerous Precancerous Pathological conditions that tend eventually to become malignant. Barrett’s Esophagus lesions are rare before the age of 21.
  • The progression from hrHPV infection → precancerous Precancerous Pathological conditions that tend eventually to become malignant. Barrett’s Esophagus lesions (cervical intraepithelial neoplasia [ CIN CIN An increased tendency to acquire chromosome aberrations when various processes involved in chromosome replication, repair, or segregation are dysfunctional. Colorectal Cancer]) → invasive cancer takes many years
  • Many precancerous Precancerous Pathological conditions that tend eventually to become malignant. Barrett’s Esophagus lesions and HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV) infections Infections Invasion of the host organism by microorganisms or their toxins or by parasites that can cause pathological conditions or diseases. Chronic Granulomatous Disease will regress.
  • May lead to more harm from psychological distress and unnecessary procedures

Strategies for Screening

Screening Screening Preoperative Care strategies can be done independently or concurrently (co-testing).

• Cervical cytology:
  • Ectocervical and endocervical cells are collected to evaluate the transformation Transformation Change brought about to an organism’s genetic composition by unidirectional transfer (transfection; transduction, genetic; conjugation, genetic, etc.) and incorporation of foreign DNA into prokaryotic or eukaryotic cells by recombination of part or all of that DNA into the cell’s genome. Bacteriology zone (area at risk for cervical cancer Cervical cancer Cervical cancer, or invasive cervical carcinoma (ICC), is the 3rd most common cancer in women in the world, with > 50% of the cases being fatal. In the United States, ICC is the 13th most common cancer and the cause of < 3% of all cancer deaths due to the slow progression of precursor lesions and, more importantly, effective cancer screening. Cervical Cancer).
  • The procedure is performed with either:
    • An endocervical brush and ectocervical spatula
    • A cervical broom Cervical broom Diagnostic Procedures in Gynecology (collects both endocervical and ectocervical cells simultaneously)
  • Preparation methods:
    • Conventional Papanicolaou (Pap) smear: Ectocervical spatula is smeared and the brush rolled onto a slide, with fixative applied immediately
    • Liquid-based thin layer cytology: Collection device is placed and swirled in the liquid fixative solution, which is then processed by the laboratory.
• HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV) testing:
  • Identifies hrHPV subtypes
  • Samples are collected from the endocervix Endocervix Uterus, Cervix, and Fallopian Tubes: Anatomy.
  • If liquid-based cytology is performed, the same cytology specimen can be used.

Cervical Cancer Screening for Average-Risk Individuals

The following recommendations are for average-risk individuals. This group includes individuals who are fully vaccinated against HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV).

• United States Preventive Services Task Force (USPSTF) recommendations:
  • No screening Screening Preoperative Care prior to the age of 21, regardless of sexual history 
  • For ages 21‒29: cytology alone every 3 years
  • For ages 30‒65, options are:
    • Cervical cytology alone every 3 years
    • hrHPV every 5 years
    • Cytology with hrHPV co-testing every 5 years 
  • Screening Screening Preoperative Care ends at the age of 65 if the patient has adequate negative screening Screening Preoperative Care.
• Updated American Cancer Society recommendations (2020):
  • No screening Screening Preoperative Care prior to the age of 25, regardless of sexual history
  • Screen individuals ages 25‒65
  • Preferred test: primary HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation.
