AIDS-related Kaposi's sarcoma is often treated by local therapy for physically or cosmetically disabling symptoms. We present the first case of a bulbar conjunctival Kaposi's sarcoma lesion to be treated with a strontium-90 ophthalmic applicator. The treatment is simple, effective and well tolerated
Because of the polymorphism of osteogenic sarcomas, examination of a biopsy specimen, which is necessarily small, cannot give an accurate evaluation of the differentiation of the whole tumor. Therefore, a test which provides an overall assessment of the functional capacity of the tumor is needed.
A total of 66 primary bone sarcomas were diagnosed in 47 beagles; 43 of these dogs were part of the 403 beagles fed 90Sr and 4 were part of the 162 controls. Multiple primary bone sarcomas were found in 15 of the 47 beagles (32%). The incidence of multiple primary bone sarcoma was restricted to the
In a series of experiments, mainly CBA/H, but also C2H/H, mice aged 3 months were injected intraperitoneally with solutions of 90Sr Cl2, the dose per mouse varying from 7 to 20 muCi, and compared with similar mice treated with 226Ra or 239Pu, discussed elsewhere. In male mice, the commonest tumour
Strontium ralenate is a new anti-osteoporosis agent. The cellular and molecular mechanism underlying the anabolic effect of strontium on bone remains to be elucidated. Osteoblasts, the main bone forming cells are known to be derived from bone marrow mesenchymal stem cells (MSCs). The present study
We report a study of strontium kinetics in two patients who received 89Sr therapy for disseminated osteogenic sarcoma, together with estimates of absorbed dose to the principal metastases and to bone marrow. In neither patient did tumour uptake of strontium have a significant effect on whole-body
Strontium-90 was inject i.v. into pregnant rats on day 18 post conception (p.c.). This caused a remarkable transplacental radioactivity uptake and accumulation in the ossification centers of the skull basis. The total radiation dose within the surface of these regions was consequently calculated to
The localization of ATPases in 7 osteogenic sarcomas of osteoblastic, chondroblastic and fibroblastic type was investigated at the fine structural level using two types of substrates: one with lead as capturing ion and one with strontium (the latter presumed to reveal sites of Na+-K+-dependent
A comparative analysis of the data of roentgenography-angiography, scanning and radiometry with strontium-85 in 54 patients showing osteogenic sarcoma and osteoblastoclastoma has demonstrated a relationship between the quantitative characteristics of the radioactive Sr inclusion and the intensity of
A number of drug classes are licensed for the treatment of osteoporosis including bisphosphonates, recombinant human parathyroid hormone (PTH), strontium, hormone replacement therapy (HRT), selective oestrogen receptor modulators (SERMS) and denosumab. This review discusses the safety of
