CONTEXT: Solid organ transplant recipients have elevated cancer risk due to
immunosuppression and oncogenic viral infections. Because most prior research has
concerned kidney recipients, large studies that include recipients of differing
organs can inform cancer etiology.
OBJECTIVE: To describe the overall pattern of cancer following solid organ
transplantation.
DESIGN, SETTING, AND PARTICIPANTS: Cohort study using linked data on solid organ
transplant recipients from the US Scientific Registry of Transplant Recipients
(1987-2008) and 13 state and regional cancer registries.
MAIN OUTCOME MEASURES: Standardized incidence ratios (SIRs) and excess absolute
risks (EARs) assessing relative and absolute cancer risk in transplant recipients
compared with the general population.
RESULTS: The registry linkages yielded data on 175,732 solid organ transplants
(58.4% for kidney, 21.6% for liver, 10.0% for heart, and 4.0% for lung). The
overall cancer risk was elevated with 10,656 cases and an incidence of 1375 per
100,000 person-years (SIR, 2.10 [95% CI, 2.06-2.14]; EAR, 719.3 [95% CI,
693.3-745.6] per 100,000 person-years). Risk was increased for 32 different
malignancies, some related to known infections (eg, anal cancer, Kaposi sarcoma)
and others unrelated (eg, melanoma, thyroid and lip cancers). The most common
malignancies with elevated risk were non-Hodgkin lymphoma (n = 1504; incidence:
194.0 per 100,000 person-years; SIR, 7.54 [95% CI, 7.17-7.93]; EAR, 168.3 [95%
CI, 158.6-178.4] per 100,000 person-years) and cancers of the lung (n = 1344;
incidence: 173.4 per 100,000 person-years; SIR, 1.97 [95% CI, 1.86-2.08]; EAR,
85.3 [95% CI, 76.2-94.8] per 100,000 person-years), liver (n = 930; incidence:
120.0 per 100,000 person-years; SIR, 11.56 [95% CI, 10.83-12.33]; EAR, 109.6 [95%
CI, 102.0-117.6] per 100,000 person-years), and kidney (n = 752; incidence: 97.0
per 100,000 person-years; SIR, 4.65 [95% CI, 4.32-4.99]; EAR, 76.1 [95% CI,
69.3-83.3] per 100,000 person-years). Lung cancer risk was most elevated in lung
recipients (SIR, 6.13 [95% CI, 5.18-7.21]) but also increased among other
recipients (kidney: SIR, 1.46 [95% CI, 1.34-1.59]; liver: SIR, 1.95 [95% CI,
1.74-2.19]; and heart: SIR, 2.67 [95% CI, 2.40-2.95]). Liver cancer risk was
elevated only among liver recipients (SIR, 43.83 [95% CI, 40.90-46.91]), who
manifested exceptional risk in the first 6 months (SIR, 508.97 [95% CI,
474.16-545.66]) and a 2-fold excess risk for 10 to 15 years thereafter (SIR, 2.22
[95% CI, 1.57-3.04]). Among kidney recipients, kidney cancer risk was elevated
(SIR, 6.66 [95% CI, 6.12-7.23]) and bimodal in onset time. Kidney cancer risk
also was increased in liver recipients (SIR, 1.80 [95% CI, 1.40-2.29]) and heart
recipients (SIR, 2.90 [95% CI, 2.32-3.59]).
CONCLUSION: Compared with the general population, recipients of a kidney, liver,
heart, or lung transplant have an increased risk for diverse infection-related
and unrelated cancers.

The concept that the immune system can recognize and destroy nascent transformed
cells was originally embodied in the cancer immunosurveillance hypothesis of
Burnet and Thomas. This hypothesis was abandoned shortly afterwards because of
the absence of strong experimental evidence supporting the concept. New data,
however, clearly show the existence of cancer immunosurveillance and also
indicate that it may function as a component of a more general process of cancer
immunoediting. This process is responsible for both eliminating tumors and
sculpting the immunogenic phenotypes of tumors that eventually form in
immunocompetent hosts. In this review, we will summarize the historical and
experimental basis of cancer immunoediting and discuss its dual roles in
promoting host protection against cancer and facilitating tumor escape from
immune destruction.
