INTRODUCTION
The prognosis of patients with supratentorial malignant gliomas still remains very
poor despite many efforts to improve it. Although there is some controversy,
cytoreductive surgery for these tumors has been advocated by numerous studies, yet the
median survival time is only 14 weeks after surgery alone. Currently, the main goals of
surgery are to make a histologic diagnosis, determine the extent of the tumor and
debulk the tumor as much as possible.
The beneficial effects of postoperative radiotherapy have been substantiated by several
prospective studies. It also has been demonstrated that the patients receiving 6,000 cGy
of radiotherapy lived longer than those receiving only 5,000 cGy. The value of adjuvant
chemotherapy in addition to surgery and radiotherapy for patients with glioblastoma
multiforme remains open to question. A study conducted by the BTSG showed a modest
prolongation of median survival time from 36 to 51 weeks by adding BCNU
(1,3-bis(2-chloroethyl)-1-nitrosourea). Other authors have reported similar results using
other chemotherapeutic agents but there are other reports which failed to demonstrate
any benefit from chemotherapy for the treatment of glioblastoma multiforme. Meanwhile,
Levin et al. have reported the results of improved survival for anaplastic astrocytoma
using PCV (procarbazine, CCNU and vincristine), indicating that it may be a tumor
grade specific response/benefit from chemotherapy.
It has been reported that ACNU
(1-(4-amino-2-methyl-5-pirimidinyl)-methy1-3-(2-chloroethy1)-3-nitro sourea
hydrochloride, or nimustine hydrochloride), a water-soluble nitrosourea, has shown
equivalent or higher activity against L-1210 tumor cell line compared with CCNU, and a
broader anti-tumor spectrum compared with other nitrosoureas. The Japanese Brain
Tumor Chemotherapy Study Group studied ACNU as a radiosensitizer. ACNU during
radiotherapy produced more radiologic tumor responses compared with radiotherapy
alone, possibly by their cellular synchronizing effect, but no survival advantage was
demonstrated.
Previous studies have evaluated the effect of chemotherapy on the survival time alone.
We initiated this trial of ACNU to determine its effect on the maintenance of tumor
response as well as survival time.
