[The effect of chemotherapy on the retention of 99mTc-methylenediphosphonate by the osteogenic sarcoma of the mouse (author's transl)].
The cytostatic action of Adriblastin on the accumulation of 99mTc-MDP by a transplantable osteogenic sarcoma in the mouse was investigated. The quantitative determination of the activity concentration in the tumor showed a concentration value 8 days after the administration of the cytostatic which was nearly twice that found in the untreated animals. This could be clearly observed in scintigrams obtained with a gamma-camera using a pinhole-collimator. The histoautoradiography likewise showed a higher concentration of the radiopharmaceutical which can be attributed to higher ossification within the tumor due to the application of the cytostatic agent. Our results indicate that scintigraphy with 99mTc-MDP is a good follow-up method during treatment with cytostatics.
