Colposcopic Findings of Cervix in VIA Positive Cases in Sylhet MAG Osmani Medical College Hospital, Sylhet, Bangladesh
Abstract
Background: Cervical cancer is a preventable disease as the different screening, diagnostic, and therapeutic procedures are effective. The screening procedures, VIA and Colposcopy are important screening tools in the evaluation of cervical pre-malignant conditions. Materials and Methods: In this cross-sectional observational study two hundred fifty VIA positive women were included. Pregnant women and women who had any operative procedure in the cervix were excluded. VIA positive patient was subjected to colposcopy and cervix was visualized for aceto-white lesion under magnification. Finding of colposcopy was recorded and interpreted using Swede Score.
Results: The age of the VIA positive patients 38.02 ± 10.41 (ranged 22 – 68) years with majority (88.4%) patients were in the age group of 22-50 years. Three-quarter of the women were multiparity. Colposcopic diagnosis was carcinoma in situ I (CINI) in 143 (57.2%) patients, CIN II in 37 (19.2%) patients CIN III in 26 (10.4%) patients, invasive cervical carcinoma in 17 (6.8%) patients and normal finding in 27 (10.8%) cases. Histpathologically 69 (27.6%) patients had carcinoma in situ (CIN) I, 49 (19.6%) patients had CIN II, 26 (10.4%) patients had CIN III, 45 (18.0%) patients had chronic cervicitis, 17 (6.8%) patients had endocervical polyp, 17 (6.8%) patients had invasive cervical carcinoma and biopsy was not done in 27 (10.8%) patients. All colposcopy positive CIN 2 (n=37), CIN 3 (n=26) and invasive carcinoma (n=17) were histopathologically proven CIN 2, CIN 3 and invasive carcinoma respectively. While 143 colposcopy positive CIN 1 cases were histopathologically CIN 1 (48.3%), CIN 2 (8.4%), chronic cervicitis (31.5%), and endocervical polyp (11.9%). Colposcopy correctly diagnosed CIN 2, CIN 3 and invasive carcinoma cervix but about half (52.3%) of the cases of CIN 1 compared to histopathology with overall accuracy of colposcopy was 71.7%.
Conclusion: This study revealed that colposcopy correctly diagnosed CIN 2, CIN 3 and invasive carcinoma cervix but about half of the cases of CIN 1 compared to histopathology with overall accuracy of colposcopy was 71.7%. So, colposcopy has a tremendous role in the evaluation of CIN and cervical carcinoma in VIA positive women.
