Summary
Mithramycin effectively controlled malignant hypercalcemia but required intermittent use for temporary management. Further research into its mechanism is needed before prolonged administration.
Area of Science:
- Oncology
- Pharmacology
Background:
- Hypercalcemia of malignancy is a common and serious complication.
- Mithramycin is an antibiotic with potential anti-cancer properties.
Purpose of the Study:
- To evaluate the efficacy of Mithramycin in controlling hypercalcemia of malignant disease.
- To assess the duration and requirements for Mithramycin treatment in such cases.
Main Methods:
- Administration of Mithramycin (Mithracin(R)) to patients with hypercalcemia of malignant disease.
- Monitoring of calcium levels and treatment response.
Main Results:
- Mithramycin rapidly controlled hypercalcemia in all patients treated.
- The control achieved was temporary, necessitating intermittent administration of Mithramycin.
- Non-toxic maneuvers like hydration and corticoids can also manage hypercalcemia.
Conclusions:
- Mithramycin offers rapid, albeit temporary, control of malignant hypercalcemia.
- Intermittent administration is currently required for sustained effect.
- Caution is advised for prolonged Mithramycin use until its mechanism in hypercalcemia is fully elucidated.
