Study of Pap Smears From Patients Enrolled on Clinical Trial GOG-171

November 5, 2010 updated by: Gynecologic Oncology Group

Morphometric Diagnosis of Atypical Glandular Lesions Using a Conventional Pap Smear From GOG-0171 Patients (Enrolled by GOG-Japan) With a Cytologic Diagnosis of Atypical Glandular Cells of Unspecified Significance (AGUS)

RATIONALE: Studying Pap smears in the laboratory from women with atypical glandular cells of unspecified significance may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is looking at Pap smears from women enrolled on clinical trial GOG-171.

Study Overview

Status

Status

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

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.

Detailed Description

OBJECTIVES:

Primary

  • To determine the diagnostic accuracy of using previously reported morphometric criteria for chromatin distribution, shortest distance between nuclei, and/or the ratio of nucleoli area to nucleus area in a conventional Pap smear from patients with a cytologic diagnosis of atypical glandular cells of unspecified significance (AGUS) to predict the presence of significant glandular lesions (i.e., adenocarcinoma in situ [AIS] or invasive cancer) and/or squamous lesions (i.e., cervical intraepithelial neoplasia [CIN2 or CIN3]) of the cervix.

Secondary

  • To optimize the diagnostic accuracy of using chromatin distribution, shortest distance between nuclei, and/or the ratio of nucleoli area to nucleus area in a conventional Pap smear from patients with a cytologic diagnosis of AGUS to predict the presence of significant glandular lesions (i.e., AIS or invasive cancer) and/or squamous lesions (i.e., CIN2 or CIN3) of the cervix.

OUTLINE: Previously collected slides from Pap smears of patients enrolled on clinical trial GOG-171 are assessed for nuclear chromatin distribution, the shortest distances between the central points of neighboring cell nuclei, and nucleoli area/nucleus area (N/N) ratio via morphometric analysis.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
55

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

DISEASE CHARACTERISTICS:

  • Cytologically confirmed atypical glandular cells of unspecified significance

    • Original Pap smear used to define the diagnosis must be available for review

  • Previously enrolled by GOG-JAPAN onto clinical trialGOG-171

    • Must have been eligible and evaluable for the primary objective of GOG-171
    • Gave permission to use specimens for future cancer research in GOG-171
  • Underwent a loop electrosurgical excision procedure/large loop excision of the transformation zone (LEEP/LLETZ) procedure on clinical trial GOG-171 to determine the presence of cervical intraepithelial neoplasia (CIN-2 or CIN-3), significant glandular lesions (AIS), or invasive cancer

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

How is the study designed?

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
Presence of CIN-2 or CIN-3, significant glandular lesions (AIS), or invasive cancer as determined by the GOG Central Pathology Review of the loop electrosurgical excision procedure/large loop excision of the transformation zone tissue specimen

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
Intensity of nuclear chromatin staining and chromatin distribution
Distance between neighboring nuclei
Nucleoli area to nucleus area ratio (N/N)

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.
February 1, 2008

Primary Completion (Anticipated)

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.
