Cervical cancer or cervical cancer caused by Human Papillomavirus Virus (HPV). There are at least 118 different types of HPV is the cause but only 8 types of HPV that are most widely spread in more than 90 percent of cervical cancer cases.
International research team led by Silvia de San Jose of the Catalan Institute of Oncology in Barcelona check the HPV types that contribute to cases of cervical cancer.
This study used data from 10,575 cases of cervical cancer in 38 countries for over 60 years. The study involved cancer cases from Europe, North America, South America, Africa, Asia and Oceania.
The results, published in the Lancet medical journal shows that there are 8 types of HPV responsible for 90 percent of cervical cancer cases. Types of HPV are types 16, 18, 45, 33, 31, 52, 58 and 35.
Researchers also identified several rare species such as HPV types 26, 30, 61, 67, 69, 82 and 91, this type can also cause cancer but the percentage is only about 1 percent worldwide.
Drug manufacturer GlaxoSmithKline and Merck & Co. have made a vaccine against strains of HPV that cause most cervical cancer. Cervical cancer is the second most common cancer suffered by women around the world.
Cervarix vaccine from GSK and Merck’s new Gardasil provides protection against HPV types 16 and 18. HPV immunization will be given to girls who are not yet sexually active, but the price of the vaccine is too expensive so can not be maximally accessible in poor countries.
“Prevention of cervical cancer through a vaccine that is still rational, and these results will help develop a second generation vaccine that can protect some types of HPV,” said De San Jose, as quoted by Reuters on Monday (10/18/2010).
