  Purpose

Primary Objectives:

  1. To evaluate the material properties, histomorphometric indices, bone mineral density (BMD), and presence of microfractures in retrieved large allograft cortical bone specimens removed from orthopaedic oncology patients.
  2. To correlate physical properties to patient demographics and medical treatment received.

Condition Intervention
Bone Cancer
 Procedure: Tissue Sample

Study Type: Observational
Study Design: Observational Model: Case-Only

Further study details as provided by M.D. Anderson Cancer Center:

Primary Outcome Measures:
  • To learn about properties (such as bone strength, bone density, and new bone formation) of removed transplant tissue and how it integrated with participant's own tissues during the time it was implanted. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To compare information such as the reasons this allograft was used and the length of time before it was removed to other patients who have received similar allograft tissues that were removed. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

A leftover sample of the removed allograft bone will be collected and used to learn about the properties (such as bone strength, bone density, and new bone formation) of the removed transplant tissue.

Groups/Cohorts Assigned Interventions
Retrieved Allograft
Patients that require the retrieval of a bone allograft (transplant).
 Procedure: Tissue Sample
A leftover sample of the removed allograft bone will be collected.

Detailed Description:

Allograft Surgery:

As a standard of care, you will be having surgery to remove allograft tissue that has failed or because there were other complications following your earlier transplant. You will be separately consented for this surgery, which will describe the procedure and its risks in detail.

Tissue Research:

If you agree to take part in this study, leftover sample of the removed allograft bone will be collected and used to learn about the properties (such as bone strength, bone density, and new bone formation) of the removed transplant tissue. This tissue will be stored at the University of Arkansas for use in this study. Any remaining leftover tissue will be destroyed by the end of December 2011.

Data Collection:

Before you have surgery, you will have an x-ray. This is also part of standard of care. If you take part in this study, this x-ray will be used to learn about the properties of the transplant tissue.

All other information will be coming from your medical record, either from your past visits or as a result of your surgery. The information being collected will include information about your graft during the time it was within your body and observations made by your surgeon at its removal.

Length of Study:

Your participation in this study will be over after your tissue and data are collected.

This is an investigational study. Up to 200 patients will be enrolled on this multicenter study. Up to 20 will be enrolled at M. D. Anderson.
