CERVICAL CANCER SCREENING IN NIS COUNTRIES
The second of these EC-funded projects (Contract # ERB IC15-CT98-0321) was designed and initiated by the applicant as the coordinator while still
in Kuopio, but at transition abroad in 1999, was transferred to Turku University
(coordinated by prof. S.Syrjänen). This project belongs to the INCO-COPERNICUS
Programme of EC, and is known as the NIS/CCE Cohort Study,
continuing until the first quarter of 2002. This study is participated
by 9 research groups
from two EC countries (Finland and Italy) and those from three NIS/CCE
countries (Russia, Belarus and Latvia), with the main focus being in the
testing of different optional diagnostic tests (PAP smear, PCR and Hybrid
Capture II) as screening tools of cervical cancer in these low-resource
settings. Based on the excellent results of the organised massscreening
programme in Finland, and on the know-how of the coordinator (having run
this programme in East-Finland for 16 years), this multi-national project
is testing the performance of three optional diagnostic tools in early
detection of cervical cancer precursors. The long-term aim is to use this
information as the basis for selecting the cost-effective strategies for
cervical cancer prevention in these three NIS countries with high-incidence
but limited resources for preventing this disease.
This combined cross-sectional and cohort study is based on meticulous examination and prospective follow-up of 3.187 women, representing patients in three categories of risk for cervical HPV infections and cancer. Due to the prospective nature of this study, the main publication activity had to be postponed until the termination of the follow-up. Thus, the full exploitation of the results was started just recently, and several important papers have been recently published.

4.Abstract:
ASSESSMENT OF GENITAL HUMAN PAPILLOMAVIRUS (HPV) INFECTIONS AS A HEALTH PROBLEM IN RUSSIA, BELARUS AND LATVIA. Measures Necessary for Their Early Detection, Treatment and Control of Cervical Cancer and Its Precursor (CIN) Lesions.
Background:
To date, over 80 different human papillomavirus (HPV) types have been recognised
and characterized, and a significant risk for the development of invasive
cervical cancer has been ascribed to infections of the high-risk HPV types
(IARC 1995). The natural history of cervical HPV infections seems to be identical
with that of cervical precancer lesions (Syrjänen, 1997). An invasive
cervical cancer invariably develops through these well defined precursor
lesions (dysplasia, CIN), the early detection and eradication of which is
a prerequisite for a successful prevention of cervical cancer. Although cervical
cancer remains to be a major health problem worldwide (>500.000 new cases/year),
it still is the only malignant human tumour which can be effectively prevented
by medical intervention, as shown by the data e.g. from Finland, where an
organized mass-screening programme has reduced the incidence of invasive
cervical cancer to the lowest figures in the world, 2.7/105 (Syrjänen,
1997; Hakama, 1997). Because of the fact that organized mass-screening programmes
are not realistic in most of the developing countries (including NIS/CCE),
other measures should be searched for to alleviate the cancer burden in these
areas, as recently recommended by the joint expert conference (WHO&EUROGIN)(Franco
et al., 1996; 1997). Such alternative measures suggested include e.g. the
screening of genital HPV infections by the available new molecular diagnostic
tools (hybridization and PCR).
Objectives:
In the present proposal, an approach is made 1) to assess the magnitude of
genital HPV infections, CIN and cervical cancer as a health problem in the
participating NIS/CCE countries, 2) to disclose the risk groups for this
disease within these countries, 3) to elucidate the optimal (and the minimum)
requirements for an appropriate detection of these risk groups by taking
into account the local (and limited) resources, and finally 4) by combining
the research and development component of this project, to create an effective
health care system in the participating NIS/CCE centers, capable of independently
diagnosing and treating genital HPV and CIN, with the decreased disease burden
due to cervical cancer as the main long-term objective. A potential European
dimension will be provided by the future implementation of such a system
in other European countries with cervical cancer as a major health problem.
Study Design:
This study is a classical population-based, crosss-sectional (prevalence)
study combined with a prospective cohort study. Thus, during the first year
of this project, consecutive series of women attending the participating
centers in the NIS/CCE are screened for cervical HPV infections and CIN,
and the positive women (=prevalence data, geographic variation) will then
comprise the cohort to be prospectively followed-up in these centers up to
the end of this 3-year project (=disease prognosis). To asssess the different
levels of risk for HPV and CIN, the study is focused on two target populations
of women in the NIS/CCE; 1) those attending the Gyn. Obst. clinics, and 2)
those attending the STD clinics. The detection of the disease will be completed
through two arms: 1) by PAP smears (ARM I), and 2) by PCR (ARM II). This
enables the comparison of the efficacy, feasibility and cost-effectiveness
of the new molecular diagnostic tools (PCR, ISH) with the traditional HPV/CIN
detection methods (PAP smear, colposcopy, biopsy). PCR-negative women will
consitute the Control Group for all HPV/CIN women, to be analysed for the
epidemiological risk factors by questionnaires. Depending on the severity
of the lesion on biopsy, the women are allocated to two mutually exclusive
outcomes: 1) prospective follow-up, and 2) prompt treatment.
Partners and Coordination:
This proposal is a joint research project, contributed by three centers in
two EC countries (Finland, Italy), and 5 centers from three NIS/CCE countries
(Russia, Belarus, Latvia), with the Coordination in Kuopio, Finland and Scientific
Coordination in Moscow, Russia.
Significance:
The main significance of the proposed cooperation will be in the fact the
existing but clearly ineffective health care system in the NIS/CCE will be
developed more efficient to cope with this major health problem. This can
only be achieved by a joint research project with the expertise in the EC
and utilizing their existing health care system as a reference.
