[Possibilities for optimizing radiotherapy of cervix cancers by measuring the enzyme peak of GPI after initial irradiation].
Following the first irradiation with a dose of 1.6 respectively 2 Gy we determined the activity of glucose-6-phosphate isomerase (GPI) and of creatine kinase in intervals of 30 minutes for 24 hours. In all patients we could observe peaks of GPI-activity 15.5 to 19.5 hours after irradiation corresponding to tumour volume and grading. Frequency depends on present lymph node metastases detected by lymphography and/or computed tomography. Possible reasons have been discussed by the viewpoint of radiation biology and the meaning with respect to an optimal radiation treatment.
