Study of Blood Immune Cells in Cancer Patients Compared to Controls

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
