At. Aas et al., CHLORPROMAZINE IN COMBINATION WITH NITROSOUREA INHIBITS EXPERIMENTAL GLIOMA GROWTH, British journal of neurosurgery, 8(2), 1994, pp. 187-192
Modern cancer therapy has improved the prognosis for several tumour ty
pes. This, however, does not apply to the largest group of brain tumou
rs, the malignant astrocytomas grades III-IV. Hence, there is need for
new ideas to improve treatment. Ca2+ and the Ca2+-binding protein cal
modulin have been shown to be involved in the processes conferring sta
bility to DNA in proliferating neoplastic cells. We have combined the
calmodulin-inhibiting neuroleptic drug chlorpromazine (CPZ), with the
anti-neoplastic drug 1,3-bis(2-chloroethyl-1)-nitrosourea (BCNU) in a
treatment regime for rats with glioma cells implanted in the brain. A
highly significant inhibiting effect upon the tumour growth was notice
d, not by CPZ or BCNU as single drugs, but with their combination.
