Improving Diagnostics in Cervical Dysplasia

Cervical cancer is the fourth most common cancer in women worldwide. It is caused by an infection with human papillomavirus (HPV). A persistent infection with HPV is associated with increased risk of precancerous lesions, which may further develop into cervical cancer. To reduce the disease burden, accurate and timely diagnosis of cervical precancerous lesions are crucial. To identify cervical precancerous lesions, women are referred to colposcopy, which is the most important diagnostic tools to detect cervical precancerous lesions. It allows close visualization of the cervix in order to collect biopsies in the area called transformation zone (TZ), which is where precancerous lesions develop. It is essential for the physician to identify the TZ during colposcopy in order to obtain correct diagnosis. For women aged ≥50 this is often a challenge as TZ naturally with age, will retract further into the cervical canal, making the area for sampling invisible, and thereby the colposcopy inadequate. Consequently, this increases the risk of developing cancer due to diagnostic delay, and the risk of several colposcopy examinations or overtreatment (cone biopsy), before a final diagnosis is achieved. Few studies suggest that pretreatment with local vaginal estrogen prior to colposcopy may improve visualization of the TZ. Thereby, obtaining more accurate biopsies from the cervix, and thus making a more accurate and timely diagnosis in the first outpatient visit. The primary purpose o…
