2. INTERNATIONAL CANCER DAYS (2ND ICD), 16 Eylül - 18 Aralık 2021, ss.229-234
Cervical cancer is the second most common cancer among women worldwide. This type of cancer is
caused by a sexually transmitted virus called Human Papillomavirus (HPV). HPV is effective in the
development of cervical cancer at a rate of 99.9%. Cervical cancer is a cancer that can be prevented by early
diagnosis with screening tests and HPV vaccine. There are two different HPV vaccines licensed by the Ministry
of Health in our country. The first is Gardasil ®, which is effective against four HPV types (6,11,16,18), and
the second is Cervarix®, which is effective against two HPV types (16,18). Finally, Gardasil®9, effective
against nine HPV types (6,11,16,18,31,33,45,52,58) approved by the World Health Organization in 2014, has
not yet been licensed in our country. There is no national vaccination program for HPV vaccination in our
country, but the Turkish Society of Gynecological Oncology recommends vaccination. It has been shown that
there is a significant reduction in the incidence and mortality of cervical precancerous lesions and cancer in
countries where HPV vaccine is routinely administered.
In our study, we wanted to show the long-term effect of HPV vaccination on the reduction in the
incidence of cervical precancerous and cancer formation, in the light of current data.
