Oui c’est tout à fait ça avant qu’elle ne retourne sa culotte sans s’en expliquer en 2007 la FDA (Food & Drug Adminstration) publiait sur son site dans un document que les infections HPV ne causent pas le cancer du col de l’utérus, même celles causées par des HPV dits à « hauts risques », mais que seules
les infections HPV « persistantes » peuvent éventuellement induire des
lésions précancéreuses au niveau du col de l’utérus.

Based on new scientific information published in the past
15 years, it is now generally agreed that identifying and typing HPV
infection does not bear a direct relationship to stratification of the
risk for cervical cancer. Most acute infections caused by HPV are
sel-limiting [1, 4-7]. It is the persistent HPV infection that may act as a tumor promoter in cancer induction [8-11]. Identifying and typing HPV is an important tool for following patients with persistent HPV infection. Repeated
sequential transient HPV infections, even when caused by « high-risk »
HPVs, are characteristically not associated with high risk of
developping squamous intraepithelial lesions, a precursor of cervical
cancer.
A woman found to be positive for the same strain (genotype) of HPV on
repeated testing is highly likely suffering from a persistent HPV
infection and is considered to be at high risk of developing
precancerous intraepithelial lesions in the cervix. It is the persistent infection, not the virus, that determines the cancer risk.
The FDA has accepted the above interpretation of current medical science, as reflected in its March 31, 2003 announcement on aproval of the digene HC2 High-Risk HPV DNA Test while making the following public statements on record [I].
« The FDA today approved expanded use of a laboratory test detect
the presence in women of human papilomavirus (HPV), one of the most
common sexualily transmitted infections. »
« The HPV DNA test does not test for cancer, but for HPV viruses
that can cause cell changes in the cervix. If left untreated, these
changes can eventually lead to cancer in some women. »
« Most women who become infected with HPV are able to eradicate
the virus and suffer no apparent long-term consequences to their health.
But a few women develop a persistent infection that can eventually lead to pre-cancerous changes in the cervix. »
« ...most infections are short-lived and not associated with cervical cancer. »

« Historically, HPV testing [15] was introduced to compensate
for the poor sensitivity and specificity of the Pap smear cytology
often used as a diagnostic tool for borderline precancerous lesions. The
only FDA approved Digene Hybrid Capture 2 (HC2) assay is commonly used
to determine if a cervicovaginal lavage sample harbors »high-risk« HPVs
[16], as an adjunctive test for evaluation of the cytologically
borderline cases [17-19]. However, it is now recognized that
persistent infection of a »high-risk« HPV, not the HPV virus itself, is
the pivotal promoter incausing cervical precancerous lesions and cancer [7-10].
Most
of HPV infections, even caused by »high-risk« genotypes, are transient
with normal Pap cytology in sexually active young women [1, 3-6]. In 93%
of the initially infected women, the same viral type is not detected
upon re-examination four menstrual cycles later [20]. The median
duration of positivity detectable by PCR for a specific HPV type in
these young women is 168 days [21]. Multiple »high-risk« HPV
infections do not constitute a higher risk for the development of
cervical neoplasia when compared with single high-risk HPV infection [22]. For
the development and maintenance of a high-grade squamous intra
epithelial lesion (SIL), the risk is greatest in women positive for the
same genotype of HPV on repeated testing [7-9]. Viral load is
not a useful parameter to predict high-grade SIL [23]. High-grade SIL is
often associated with a viral DNA load lower than that observed in less
severely affected cells [24] »
