Transcript of "Pap Smears"

  1. 1. Pap Smears Anna Mae Smith, MPAS, PA-C Lock Haven University Physician Assistant Program
  2. 2. Cervical Cancer <ul><li>8th most common malignancy in women </li></ul><ul><li>accounts for 18% of all gynecologic cancers in the US </li></ul><ul><li>Reduced mortality from cervical cancer as much as 75% </li></ul><ul><li>in past 45 years, its incidence has decreased from 45 to 15 per 100,000 women </li></ul><ul><li>an increase has occurred in the prevalence of dysplasia and preinvasive lesions </li></ul>
  3. 4. Pap Smears <ul><li>The Pap smear (more than many other screening tests) has proven its cost effectiveness. </li></ul><ul><li>Early detection of pre-malignant lesions by Pap smears prevent at least 70% of potential cervical cancers. </li></ul>
  4. 5. Of the 30% who actually develop cervical cancer: <ul><li>8% elude cytological detection because of </li></ul><ul><ul><li>imperfections in cytological technology </li></ul></ul><ul><ul><li>biologic behavior of malignant lesions </li></ul></ul><ul><li>22% represent women who develop cervical cancer because of failure to regularly seek Pap smears => women whose cancers could have been prevented with early detection and treatment. </li></ul>
  5. 6. Do not withhold OCPs from women with an abnormal Pap smear . <ul><li>No reason to believe OCPs will hasten the progression of an existing cervical lesion </li></ul><ul><li>Tragic result => unintended pregnancy => makes diagnosis more difficult => treatment is delayed. </li></ul>
  6. 7. Risk Factors for Cervical Cancer <ul><li>early onset of intercourse </li></ul><ul><li>three or more sexual partners </li></ul><ul><li>male partner who has had other partners </li></ul><ul><li>clinical history of HPV </li></ul><ul><li>first child prior to age 20 </li></ul><ul><li>exposure to DES in utero </li></ul><ul><li>cigarette smoking </li></ul>
  7. 8. Protective Factors <ul><li>virginity </li></ul><ul><li>long-term celibacy </li></ul><ul><li>life-long mutual monogamy </li></ul><ul><li>long-term use of condoms </li></ul>
  8. 9. No Effect on Cervical Cancer <ul><li>history of HSV </li></ul><ul><li>circumcision status of male partner </li></ul><ul><li>religious background </li></ul><ul><li>number of pregnancies </li></ul>
  9. 10. Effect of race and social economic status is controversial . <ul><li>higher rates among African-American women </li></ul><ul><li>higher rates among women of lower social economic status </li></ul><ul><li>unclear whether related to access to Pap smears and other medical care or other undetected confounding variables </li></ul>
  10. 11. HIV Infection and Cervical Cancer Risk <ul><li>Pap smears at least annually </li></ul><ul><li>baseline colposcopic evaluation at time of initial diagnosis of HIV </li></ul><ul><li>colposcopy after single reading of ASCUS or SIL Pap </li></ul><ul><li>aggressive treatment of cervical disease will prolong life in most cases </li></ul>
  11. 12. Timing of Pap Smear <ul><li>any time that menstrual bleeding is not present </li></ul><ul><li>optimal timing </li></ul><ul><ul><li>midcycle </li></ul></ul><ul><ul><li>no intercourse for 24 hours prior </li></ul></ul><ul><ul><li>nothing in vagina for 48 hours prior </li></ul></ul><ul><ul><li>no douching </li></ul></ul>
  12. 13. Pap Sampling <ul><li>Moisten speculum with warm water </li></ul><ul><li>Never use other lubricants </li></ul><ul><li>Visualize the entire cervix </li></ul><ul><li>Remove excess cervical mucus </li></ul><ul><li>Sample the ectocervix first using the spatula </li></ul><ul><li>Sample the endocervix using the brush </li></ul><ul><ul><li>Thinprep will do both at the same time. </li></ul></ul>
  13. 14. Pap Procedure continued <ul><li>Evenly distribute the sample over the side and spray immediately! </li></ul><ul><li>Must obtain cells from the transformation zone </li></ul><ul><li>Use correct order in collecting samples </li></ul><ul><ul><li>Pap smear </li></ul></ul><ul><ul><li>GC culture </li></ul></ul><ul><ul><li>chlamydia </li></ul></ul>
  14. 17. Pap Smear Technique <ul><li>Must obtain cells from the transformation zone </li></ul><ul><li>Use spatula </li></ul><ul><li>Spray </li></ul><ul><li>Use cytobrush …insert into OS of T-zone not visible </li></ul><ul><li>Spray again </li></ul>
  15. 19. Pap Slide Preparation <ul><li>1st, sample exocervix by rotating wooden spatula around 360 degrees </li></ul><ul><li>immediately spread sample on glass slide </li></ul><ul><li>2nd, sample endocervix with cytobrush or with saline-moistened cotton-tipped applicator plate this sample directly over 1st sample by gently rolling over the slide </li></ul><ul><li>fix the sample immediately to avoid air drying </li></ul>
  16. 21. Pap Smear Consensus Statement (August 1987) <ul><li>all women who are, or who have been sexually active, or who have reached 18 years of age, (should) have an annual Pap test and pelvic exam </li></ul><ul><li>after a woman has had 3 or more consecutive, satisfactory, normal annual exams, the Pap test may be performed less frequently at the discretion of her physician as long as she has no other risk factors! </li></ul>
  17. 22. Pap Smear Screening Intervals: Extremely Low-Risk <ul><li>virginal </li></ul><ul><li>never an abnormal Pap and > 5 benign Pap smears and hysterectomy for benign disease </li></ul><ul><li>> 10 benign Pap smears, including 1 at older than 60 years; presently over 65 years old </li></ul>
