Latent Tuberculosis Infection in Cancer Patients

This study has been completed.
Information provided by (Responsible Party):
M.D. Anderson Cancer Center Identifier:
First received: July 25, 2007
Last updated: September 22, 2011
Last verified: September 2011

Primary Objective:

1. To evaluate the performance of the new T-SPOT.TB test and the conventional TST for screening of Latent Tuberculosis infections in patients with cancer and those undergoing Hematopoietic Stem Cell Transplant.

Secondary Objectives:

  1. To examine the factors associated with positive response to T-SPOT.TB and the TST (tuberculin skin test) in patients with anergy.
  2. To determine the impact of immunosuppressive and antineoplastic therapy on the screening performance of T-SPOT.TB and the TST in cancer patients.

Condition Intervention
Advanced Cancer
Other: T-SPOT TB test

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective

Primary Outcome Measures:
  • Rate of Positive Results of T-SPOT.TB (%) [ Time Frame: Study period 2 Years ]
    Number participants with postitive T-SPOT.TB test results compared to total positive results, derived from Center for Disease Control (CDC) Criteria used for LTBI positive skin test (i.e. a tuberculin skin test (TST) with 5 mm or more of induration). For those individuals with >5 mm induration on TST, chest radiograph performed. Fisher's exact test used to assess the association between categorical variables and the testing results of T-SPOT.TB or TST.

Biospecimen Retention:   Samples With DNA
A blood sample will be collected and used to perform the T-SPOT. TB test.

Enrollment: 24
Study Start Date: June 2007
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Latent Tuberculosis Infection
Patients with cancer at risk for developing active tuberculosis (TB).
Other: T-SPOT TB test
Extra blood draw, followed by ten minutes rest and the injection of Tuberculin subcutaneously on forearm.
