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

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.
- 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.
