susceptible to chemically-induced, as well as spontaneous, tumors. Shankaran, V. et al. IFN and lymphocytes prevent primary tumor development and shape tumor immunogenicity. Nature , 410, 1107–1111 (2001)
Pham SM, 1995. Ann. Thorac.Surg. 60:1623–26
608 cardiac transplant patients at the University of Pittsburgh between 1980 and 1993, the prevalence of lung tumors was 25-fold higher than in the general population .
(A) Age- and sex-matched mice were inoculated with 100 ug MCA and monitored for tumor development for 160 days.
(B) Mice housed in a specific pathogen-free facility were monitored for spontaneous tumor development between 13–24 months.
(C) Infiltrating lymphocytes correlate with the favorable clinical prognosis (ovarian, colon).
(d) Adoptive transfer of tumor specific T cells suppresses tumor growth.

Immunosuppressed transplant recipients have higher incidences of cancers

5692 renal transplant patients from 1964–1982 howed increased standardized cancer incidence ratios for colon, lung, bladder, kidney, ureter, and endocrine tumors compared to the general population.

CANCER IMMUNOSURVEILLANCE IN HUMANS
(a)Immunosuppressed transplant recipients display higher incidences of cancers.
(b) Cancer patients can develop spontaneous adaptive and innate immune responses to the tumors.
