title: [Histological examinations of late changes of bone marrow and bone following local fractionated gamma irradiation in patients with genital carcinoma (author's transl)].
abstract: In 25 patients iliac crest biopsies have been taken after radiation therapy of genital carcinoma. The radiation doses in the biopsied region ranged up to about 3,000 rads. The time interval from the end of radiation until the control biopsy was 2 months or longer, up to 25 years. The immediate consequences of the radiation, compared with the pretherapeutic picture, have been analyzed in an earlier study (Beil et al., 1974). By histomorphotometric analysis of the samples it can be shown that a more or less severe atrophy of the bone marrow is persisting in the irradiated area for years. The atrophy is accompanied either by normal or increased bony trabecularization, together with increased osteoblastic and -clastic activity. These disturbances are likely to depend of a chronic distortion of the marrow capillarization, which may be influenced by the individual RES activity; different types of the reticuloendothelial response can be demonstrated in our material. Whether this response has a bearing regarding the prognosis of the tumours condition itself remains a matter of speculation, to be proved by further investigations.
