Relationship Between Computed Tomography Manifestation and Histopathological Classification of Thymic Epithelial Tumors

September 19, 2017 updated by: Le Viet Anh, MD, Military Hospital 103

Evaluate the Relationship Between Computed Tomography Manifestation and Histopathological Classification of Thymic Epithelial Tumors

the World Health Organization (WHO) has proposed a classification of histopathological thymic tumor and it significance in prognosis. Chest computed tomography (CT) is the most common method to evaluate thymic epithelial tumors before operation. Therefore, the question is to predict the histopathological type of thymic epithelial tumors before surgery based on CT-scan images , to help determine treatment strategy and prognosis. In Vietnam, there are no published literature on this issue.

Detailed Description

  1. Introduction: the World Health Organization (WHO) has proposed a classification of histopathological thymic tumor and it significance in prognosis. Chest computed tomography (CT) is the most common method to evaluate thymic epithelial tumors before operation. Therefore, the question is to predict the histopathological type of thymic epithelial tumors before surgery based on CT-scan images , to help determine treatment strategy and prognosis. In Vietnam, there are no published literature on this issue.

  2. Materials and methods:

    2.1. Cross-sectional descriptive study on 53 patients with diagnosed of thymoma by CT and had postoperative histopathology results as thymic epithelial tumors

    2.2. Time and Place: in Departement of CTVS, Military Hospital 103, Vietnam from 10/2013 to 7/2017.

    2.3. methods:

    • study in chest CT scan:

      • Measure the maximun diameter of the tumor
      • The contour: smooth contour or irregular contour
      • The shape: round, oval and plaque base on the ratio between long axis and short axis of the tumor
      • Some other characteristics: Degree of enhancement, Level of drug absorbed, Calcification, Invasion the local organs and Capsular destruction.

    • Histopathological study: based on the 2004 WHO classification:

      • Thymoma: type A, AB, B1, B2, B3
      • Thymic carcinoma
    • Data processing: use software Epi Info 2000.

  3. Expectation of results

    • Relationship between the size and histopathological type of thymic epithelial tumors.
    • Comparison of some characteristics of the tumor on preoperative chest CT scans and histopathological type of thymic epithelial tumors

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.
Interventional

Enrollment (Actual)

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.
2

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

17 years to 67 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • All of patient have a chest CT scan pre-operation and a result of thymic epithelial tumors postoperative histopathology

Exclusion Criteria:

  • Incomplete or loss the CT and postoperative histopathology

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: CT and histopathological classification
With each histopathological type of thymic epithelial tumors, we measure the maximun diameter in chest CT scan. Comparison of some characteristics of the tumor on preoperative chest CT scans and histopathological type of thymic epithelial tumors .
Other: CT and histopathological classification
Cross-sectional descriptive study on 53 patients with diagnosed of thymoma by CT and had postoperative histopathology results as thymic epithelial tumors. Base on the characteristics in Chest CT scan in each postoperative histopathology results.

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 (Actual)

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.

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.
