Study of Natural History of Human Papillomavirus (HPV) Infections in Adult Women With Recurrent Conizations in Norway

April 16, 2015 updated by: GlaxoSmithKline

A Retrospective Epidemiological Study of Natural History of HPV Infections in Women Aged 18 Years and Above With Recurrent Conization Following a Primary Conization for High Grade Lesions/ Microinvasive Cervical Carcinomas, in Norway

This is a register-based, epidemiological study of HPV type distribution in women aged 18 years and above with recurrent conization following a primary conization for high grade lesions/ microinvasive carcinomas. This study will involve data collection from different databases in the Cancer Registry of Norway.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Probability Sample

Study Population

Women aged 18 years and above registered in the Cancer Registry of Norway.

Description

Inclusion Criteria:

All subjects must meet the following criteria at study entry:

  • Women aged 18 years and above at the time of the collection of the primary cone specimen;
  • Who have undergone for the first time a conization due to high grade lesions or microinvasive cervical carcinomas, histologically diagnosed in 2003, with possible extension backwards in time;
  • Availability of recurrent cone specimen with high grade lesions/ microinvasive cervical carcinomas or invasive cervical cancer;
  • Availability in designated local laboratories of the primary and recurrent cone specimens;
  • The cone specimen was adequately preserved;
  • Written informed consent obtained from the subject. If the subject is deceased, the cone and biopsy specimens will be used according to prior approval from the Ethics Committee.

Exclusion Criteria:

None.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Cohort A
Women aged 18 years and above, diagnosed with high grade lesions or microinvasive cervical carcinomas in primary conization performed and registered in the Cancer Registry of Norway, and presenting with recurrent conization with high grade lesions or microinvasive cervical carcinoma or invasive cervical carcinoma.
Procedure: Cancer Registry of Norway (database)
Review of database to identify women with primary conization presenting with high grade lesions/ microinvasive cervical carcinomas. Recurrent cones with high grade lesions/ microinvasive cervical carcinomas or invasive cervical cancer will be identified for all women with primary cones.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
HPV-types as single group considered as new infections in recurrent conizations with high grade lesions, microinvasive cervical carcinomas or ICC diagnosis.
Time Frame: At the end of the study.
At the end of the study.
HPV-types as single group considered as persistent infections in recurrent conizations with high grade lesions, microinvasive cervical carcinomas or ICC diagnosis.
Time Frame: At the end of the study.
At the end of the study.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
HPV-types as individual types or as different groups considered as new infections in recurrent conizations presenting high grade lesions, microinvasive cervical carcinomas or ICC diagnosis.
Time Frame: At the end of the study.
At the end of the study.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2010

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
