Background: Cervical cancer (CC) is one of the primary causes of gynaecological cancer death. Cervical cancer is the fourth most frequent cancer worldwide, and it is the second most common cancer in Bangladesh. The stage of cervical cancer at diagnosis has a significant impact on survival. Cervical cancer mortality is high in Bangladesh due to late detection and limited management facilities. The aim of the study was to determine the pattern of human papillomavirus (HPV) genotype among colposcopy diagnosed cervical precancerous lesions.
Methods: This cross-sectional study was conducted in the department of gynecological oncology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka. Total of 142 women attending the colposcopy clinic of BSMMU.
Results: The mean age was found 38.7±7.3 years with a range from 30 to 60 years. 10 (7.0%) patients were found HPV 16 positive followed by 1 (0.7%) HPV 18, another hr-HPV 3 (2.1%), HPV 16 and other hr-HPV 3 (2.1%) and HPV 16, HPV 18 and other hr-HPV 1 (0.7%). Regarding colposcopy reports 99 (69.7%) patients had CIN I, 33 (23.7%) had CIN II and 10 (7.0%) had CIN III identification by colposcopy reports. 61 (43.0%) patients had CIN I followed by 15 (10.6%) had CIN II, 11 (7.7%) had CIN III, 7 (4.9%) had CIS, and 48 (33.8%) had normal or squamous metaplasia by histopathological reports.
Conclusions: It can be concluded that among all the 14 hr-HPV genotype HPV 16 is more prevalent while HPV18 prevalence was very low in colposcopy diagnosed cervical precancer cases. The study revealed HPV16 was more common among high grade lesions.
