A comparative Study to Assess the Accuracy of Colposcopic Examination and Pap Smear Cytology As Screening Test In Unhealthy Cervix (original) (raw)

It was a prospective comparative study conducted in gynecology OPD of Burdwan Medical College and Hospital on 100 women attending OPD with complains of white discharge, irregular menstruation, post coital bleeding or post-menopausal bleeding. Pap smear, colposcopy with application of 3% acetic acid and on spot cervical biopsy in indicated cases was done. 71% of women were in the age group 20-40 years. 54% had parity of 3 to 4. 69% of women presented with complain of white discharge. 88% had normal Pap smear, 1% had LSIL, 2% had HSIL and 4% had ASCUS on Pap smear. 40% of women had aceto-white reaction on colposcopy, 6% had low grade lesions and 54% had normal colposcopy findings. Final histopathology correlated with a diagnosis of CIN 2/3 in 6%, CIN 1 in 1% and squamous cell carcinoma in 4%, while 89% had chronic nonspecific cervicitis. 72.72% of all those with a positive histopathology presented with complain of white discharge and positivity increased as the parity increased. Overall sensitivity of Pap smear was72.72% which was much lower as compared to colposcopy (100%). But the specificity of Pap smear was 95.5% and of colposcopy was 67.42%. Hence colposcopy is a superior test for the screening of cervical cancer as it is more sensitive than Pap smear in detecting precancerous lesions.
