Large, Randomized Study Confirms HPV Testing Is More Sensitive Than Both Conventional and Liquid-Based Pap Test
PR Newswire 2006-06-09
A study of more than 33,000 women published in the June issue of the Journal of the National Cancer Institute found that testing for high-risk types of the human papillomavirus (HPV) is a significantly more sensitive tool for cervical cancer screening than either conventional or liquid-based cytology (Pap testing), announced Digene Corp. (NASDAQ: DIGE).
The study,
which used Digene's Hybrid Capture 2 High-Risk HPV DNA Test(R) (also called The
Digene(R) HPV Test), was funded in part by the European Union and the Italian
Ministry of Health.
"HPV
testing for high-risk types [of the virus] was more sensitive than both
conventional (by approximately 40 percent) and liquid-based (by approximately 30
percent) cytology," concluded the study authors, led by Guglielmo Ronco of
the Unit for Cancer Epidemiology, Centro per la Prevenzione Oncologica in
Turin
,
Italy
. The analysis of preliminary results from the New Technologies for Cervical
Cancer Screening (NTCC) Study, which was conducted at nine organized cervical
cancer screening programs throughout
Italy
, included more than 33,000 women age 35 and older.
Upon reviewing
the study results, Mark S. DeFrancesco, MD, Chief Medical Officer of Women's
Health
Connecticut
, commented, "These findings are important for physicians and payers when
deciding how to integrate the coming new HPV vaccine into actual practice.
Clearly, HPV testing remains an important component of cervical cancer
screening. Since the vaccine will not provide complete or immediate protection,
or perhaps even be appropriate for every woman, screening will continue to be
critical for the foreseeable future. The combination of an HPV vaccine program
long-term, and continued screening with Pap and HPV testing appears to be the
most practical and effective approach to cervical cancer prevention."
Digene markets
the only FDA-approved and CE-marked test for high-risk HPV, a virus that causes
virtually all cases of cervical cancer. In the
United States
, The Digene HPV Test is approved for use along with the Pap to screen women age
30 and older, the group most at risk for developing cervical cancer.
"This is
a milestone study in that it is the first randomized, controlled study to
compare HPV DNA testing to both conventional and liquid-based cytology,"
said Attila T. Lorincz, PhD, Digene's Chief Scientific Officer and Senior Vice
President of Research and Development. "It strongly reinforces results from
earlier, smaller screening studies showing that the use of HPV testing as part
of cervical cancer screening significantly increases our confidence that no
woman at risk of malignancy will go undetected."
Worldwide,
cervical cancer affects more than 400,000 women annually and, after breast
cancer, is the second most common malignancy found in women. In the
United States
, there are an estimated 9,710 cases of cervical cancer resulting in
approximately 3,700 deaths each year.
