Retrospective Study of Keloid Disorder

October 1, 2016 updated by: Tirgan, Michael H., M.D.
Purpose of this retrospective study is to review and analyze the information and data that has been already been generated during the course of routine practice of medicine by the investigators from 2007 up until Sept 1, 2016 from keloid patients who have sought medical care or medical advice for their keloid disorder.

Study Overview

Status

Status

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

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

To retrospectively review and analyze clinical data that has already been collected from keloid patients including photographs taken of keloid lesions during routine practice of medicine by the investigators 1) To better understand natural history of keloid disorder (KD), 2)To determine the ethnic incidence and prevalence of keloid, 3) To determine the rate of familial keloids, 4) To determine response to different treatment modalities, 5) To determine risk factors for development and worsening of keloid lesions.

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.

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
Measure Description
Time Frame
Rate of development of massive, semi-massive and large Keloids
Time Frame: 1-5 years after surgery
Keloid Recurrence after surgery is a real-world outcome, one that takes time to develop. Study will intend to explore the long term rate of keloid recurrence after surgery. This rate will be reported as percentage of patients who undergo surgery and end up with developing a massive, semi-massive or large recurrent keloid
1-5 years after surgery

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
Measure Description
Time Frame
Rate of poor aesthetic outcome after ear surgery
Time Frame: 1-5 years after surgery
Surgical intervention often results in loss of ear tissue and poor aesthetic outcome. Although fully expected, the actual rates of this outcome is unknown. Study intends to report the actual rate of disfigurement and poor aesthetic outcome after ear surgery for removal of keloid lesions.
1-5 years after surgery

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.

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.
