Thymomas are the only tumors that are proven to generate mature T
cells from immature precursors. It is unknown, however, whether
intratumorous thymopoiesis has an impact on the peripheral T-cell pool
and might thus be related to the high frequency of thymoma-associated
myasthenia gravis. This study shows, using fluorescence-activated cell
sorting-based analyses and T-cell proliferation assays, that
thymopoiesis and T-cell function in thymomas correspond with
immunologic alterations in the blood. Specifically, the proportion
of circulating CD45RA+CD8+ T cells is
significantly increased in patients with thymoma compared with normal
controls, in accordance with intratumorous T-cell development that
is abnormally skewed toward the CD8+ phenotype. Moreover,
it is primarily the proportion of circulating CD45RA+CD8+ T cells that decreases after
thymectomy. The results also demonstrate that T cells reactive toward
recombinant autoantigens are distributed equally between thymomas
and blood, whereas T-cell responses to foreign antigen (ie, tetanus
toxoid) are seen only among circulating T cells and not among
thymoma-derived T cells. These functional studies support the
hypothesis that thymopoiesis occurring within thymomas alters the
peripheral T-cell repertoire. Because many thymomas are enriched with
autoantigen-specific T cells, a disturbance of circulating T-cell
subset composition by export of intratumorous T cells may contribute to
paraneoplastic autoimmune disease arising in patients with thymoma.
