Inflammatory Response and Tissue Fibrosis/ Lymphatico-venous Bypass

May 5, 2015 updated by: M.D. Anderson Cancer Center

Determination of the Effect of Lymphatico-venous Bypass Surgery on Inflammatory Responses and Tissue Fibrosis

The goal of this clinical research study is to measure the amount of inflammatory proteins inside the body before and after lymphatico-venular bypass surgery. This will help doctors learn if anti-fibrotic or anti-inflammatory drugs/treatments given with the surgery can improve how well the surgery works.

Study Overview

Status

Status

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

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

If you choose to take part in this study, you will have 1 small piece of tissue (about the size of a pencil eraser) collected from the arm with the lymphedema and another small piece of tissue will be collected from the unaffected arm. A total of 4 samples will be collected by excisional biopsy (2 samples before the surgery and 2 more samples again 6 months after the surgery). To collect an excisional biopsy, the area of skin is numbed with anesthetic and a small cut is made to remove all or part of the affected tissue.

Blood (about 5 teaspoons each time) will also be drawn before the surgery and 1 more blood sample again 6 months after the surgery. If possible, the blood samples will be collected during already scheduled blood draws to avoid additional needle sticks.

The tissue and blood samples will be used for testing to evaluate the level of the tissue inflammation and to check for any build-up of excess tissue.

Length of Study:

After both tissue and blood samples have been collected, your participation in this study will be over.

This is an investigational study.

Up to 30 patients will take part in this study. All will be enrolled at MD Anderson.

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

All

Sampling Method

Non-Probability Sample

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.
Punch Biopsy
Procedure: Punch Biopsy
5 mm punch biopsy specimens from the affected, lymphedematous limb will be obtained just prior to lymphatico-venular bypass and six (6) months after lymphatico-venular bypass. Punch biopsies will be obtained from the radial (lateral) aspect of the upper arm approximately 10cm above the olecranon process. Biopsy specimens will be collected from the contralateral (normal) arm at the exact same location.

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.
