PURPOSE: We have evaluated irradiation doses received at location of s
econdary solid tumors occurring after bone marrow transplantation (BMT
) in five of 147 patients grafted for severe aplastic anaemia. RESULTS
: All 5 tumors occurred within the radiation field penumbra. The estim
ated received dose varied from 6 Gy for one inner field secondary tumo
r, to 2.5 Gy for the remaining secondary tumors. CONCLUSION: Tumors ma
y arise in the zone where the delivered radiation dose drops dramatica
lly. Irradiation, with associated cofactors, may promote the developme
nt of epidermoid carcinoma in irradiated patients for BMT.
