Study of Blood Immune Cells in Cancer Patients Compared to Controls

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

Tumors have a systemic immune modifying effect. They affect the immune system similarly to states of chronic inflammation and these effects can:

  • be monitored through analysis of nk t and myeloid cells mainly through studies of the zeta chain but also through other means
  • may be decreased following effective anticancer therapy - may even be used to study the effectiveness of anticancer therapy
  • are important to monitor if the investigators plan on formulation of systemic immune therapy Thus immumonitoring of systemic blood cells may turn out to be an important prognostic and predictive factor in many cancer types

Solid Carcinoma

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Observational Immunomonitoring Study of NK/T and Myelocites Status in Cancer Patients and Controls

Further study details as provided by Hadassah Medical Organization:

Primary Outcome Measures:
  • changes in immune markers mainly cd247-zeta chain - levels in cancer patients undergoing therapy [ Time Frame: 4-2013 24 month ]
    Hopefully by this time the investigators will be able to see if there are lower zeta chain intracellular expression levels in cancer patients and whether response to therapy enhances recovery of zeta chain

  • levels of zeta chain -cd247 in cancer patients [ Time Frame: till begining of 2013 ( putative) ]
    intracellular levels of cd247 compared to other intracellular proteins and other markers of immune response will be monitored in patients with cancer and a control group in cancer patients the investigators will conduct several tests to analyze effects of therapy

Biospecimen Retention:   Samples Without DNA

The investigators will collect peripheral blood for facts analysis of intracellular levels of proteins.

Some of these cells may be frozen for longer periods of time for comparison with other new samples.

Estimated Enrollment: 100
Study Start Date: March 2011
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
cancer patients
as described patietns with solid cancer about to be treated with anticancer therapies
control group
normal populations who domated blood for further use

Detailed Description:

CD247 Known also as the zeta chain is important for relaying T-cell induced signal transduction.

Interestingly studies by Baniash and others have demonstrated that this chain is down regulated in states of chronic inflammation and cancer in peripheral blood T cells and also in NK cells However there has not been a prospective study of this marker in cancer and control patients such a study will reveal not only the levels of CD247 in immune cells of cancer patients compared to controls but may reveal the effect of anticancer therapies on CD247 in cancer patients such a study may contribute significantly to our ability to monitor systemic immune system characteristics in cancer patients and help in any further studies of immunomodulation such as vaccination schemes in such patients
