One of the prerequisites for effective screening is the availability of a suitable cervical screening test that has adequate sensitivity and specificity for detection of precancerous lesions and that yields reproducible results. Such a test should be cheap, simple, and easy to apply; without side effects or complications; as painless as possible; and socio culturally acceptable. 5 R. Sankaranarayanana,T, L. Gaffikin , M.

FOR DEVELOPMENT OF PRECANCEROUS LESIONS OF CX We need infection with HPV Persistence of virus Leads to precancerous lesions If they don’t clear then invasive cancer There is no viremia of natural infection It is only from local tissue changes that we can diagnose premalignant lesions So screening involves exfoliated cells from TZ, from endocervical glands, and HPV DNA Presenct in tissue 10 DR.Maninder Ahuja VP FOGSI 4/8/2015 11 DR.Maninder Ahuja VP FOGSI 4/8/2015 Screening methods available VISUAL INSPECTION: VIA and VILLI (subjective visual inspection with acetic acid &lugol’s iodine Cytology : Pap Smear, LBC (Liquid based cytology) HPV DNA Test: High Risk HPV DNA Test / HPV Typing Follow up with colposcopy or directed biopsy or treat with ablative methods or excisional methods 12 DR.Maninder Ahuja VP FOGSI 4/8/2015 When to start screening?

Women should not be screened regardless of the age of sexual initiation or other risk factors.? 21–29 years Recommends screening with cytology every 3 years. Grade: A recommendation. Screening with cytology alone every 3 years is recommended. 30–65 years Recommends screening with cytology every 3 years or for women who want to lengthen the screening interval, screening with a combination of cytology and HPV testing every 5 years. Grade: A recommendation. Screening with cytology and HPV testing (“co-testing”) every 5 years (preferred) or cytology alone every 3 years (acceptable) is recommended. HPV vaccinated Women who have been vaccinated should continue to be screened. Recommended screening practices should not change on the basis of HPV vaccination status. 14 DR.Maninder Ahuja VP FOGSI society, american socieity of colposcopy and cervical pathology, american society for clinical pathology) 4/8/2015 Older than 65 years Recommends against screening women who have had adequate prior screening¶ and are not otherwise at high risk for cervical cancer. Grade: D recommendation. After hysterectomy Recommends against screening in women who have had a hysterectomy with removal of the cervix and who do not have a history of a high-grade precancerous lesion (ie, CIN 2 or 3) or cervical cancer. Grade: D recommendation Women with evidence of adequate negative prior screening¶ and no history of CIN2+ within the last 20 years should not be screened. Screening should not be resumed for any reason, even if a woman reports having a new sexual partner. Women of any age following a hysterectomy with removal of the cervix who have no history of CIN2+ should not be screened for vaginal cancer. Evidence of adequate negative prior screening is not required. Screening should not be resumed for any reason, including if a woman reports having a new sexual partner. high-risk populations who may need more intensive or alternative screenin. 15 These special populations include women 1) with a history of cervical cancer, 2) who were exposed in utero to diethylstilbestrol (DES), and 3) who are immune-compromised (eg, infection with human immunodeficiency virus). 4/8/2015 DR.Maninder Ahuja VP FOGSI WHO Guidelines for screening cancer cervix •New programmes should start screening women aged 30 years or more, and include younger women only when the highest-risk group has been covered. •Existing organized programmes should not include women less than 25 years of age in their target populations. •If a woman can be screened only once in her lifetime, the best age is between 35 and 45 years. contd…… 16 DR.Maninder Ahuja VP FOGSI 4/8/2015 Contd…. •For women over 50 years, a five-year screening interval is appropriate. • In the age group 25-49 years, a three-year interval can be considered if resources are available. •Annual screening is not recommended at any age. • Screening is not necessary for women over 65 years, provided the last two previous smears were negative. 17 DR.Maninder Ahuja VP FOGSI 4/8/2015 18 DR.Maninder Ahuja VP FOGSI 4/8/2015 What is critical for Pap smear: •Accurate sampling. •Adequate preservation. •Complete evaluation. •Meaningful interpretation. 19 DR.Maninder Ahuja VP FOGSI 4/8/2015 WHEN? 8th – 12th DAY OF MC CERVICAL MUCUS IS ABUNDANT EXT.
