Organ culture of craniopharyngioma and its cellular effects induced by colloidal chromic phosphate.

Since a marked clinical improvement has been reported following chromic phosphate treatment in recurrent craniopharyngioma, we have attempted to study the in vitro cellular changes of two craniopharyngiomas maintained in organ culture system and subsequently treated with colloidal chronic phosphate. When incubated for 24 and 48 hours respectively, at a concentration of 10 muCi/ml. of colloidal 32P, only vacuolar degeneration and hyperchromasia of the tumor cells have been observed. When incubated with 50 muCi/ml. for 24 hours, further cellular degeneration and focal necrosis begin to appear. Up to 48 hours after 50 muCi/ml. obvious necrosis and extensive degeneration become apparent. Autoradiography confirms the fact that radioactive material is absorbed by the tumor cells. Brain tumors when maintained in an organ culture system may serve as a useful model for the evaluation of the effects of various chemotherapeutic and radiotherapeutic agents in vitro.[1]
