26 patients, average age of 7.3 years, has biopsies of a brain stem tumor. 62% of the patients presented with hydrocephalus, and ventriculoperitoneal shunts were placed 7-10 days prior to biopsy. The midbrain was biopsied 13 times, the pons 3 and the medulla 12 times. Tissue for histopathologic examination was obtained at each operation and demonstrated astrocytoma in 13 patients,
glioblastoma
in 6, 'no tumor seen' in 5 and ependymoma in 2. Astrocytomas were usually located in the upper brain stem, and all of the glioblastomas were located in the medulla. The operative mortality was zero, and the morbidity was largely related to increased cranial nerve deficit. All the astrocytoma patients were treated with radiation only; whereas, 4 patients with
glioblastoma
were treated with vincristine, CCNU and methylprednisone in addition to radiation as described by the Children's
Cancer
Study Group (CCG-944). 3 patients with 'no tumor' were not treated and are alive and well 15-41 months following operation. 2 patients with no tumor were treated, one as a glioblastoma multiforme, subsequently verified at postmortem examination, and one as a midbrain astrocytoma. 1 patient with astrocytoma died 3 months following operation, all the remainder are living and well 4-51 months following operation. Irrespective of the treatment, all 7 patients with
glioblastoma
expired within 9 months of diagnosis. The prognosis for survival for patients with brain stem astrocytoma is superior to those with glioblastoma multiforme. Specific histopathologic correlation with clinical management may lead to improved and prolonged survival for patients with brain stem glioma.

One boy, given radiotherapy and cytostatic drugs for a rhabdomyosarcoma died nine years later of acute leukaemia. A girl, who had received radiotherapy for an inoperable suprasellar tumour and also given cytostatic drugs, fell ill seven years later with a
glioblastoma
. Among a total of 750 children with
malignant neoplasm
observed by the authors, a permanent cure rate of about 50% is to be expected among about 300 children treated recently. If this rate applies to the entire Federal Republic of Germany, about 1,000 children are likely to be cured annually. In these circumstances it is likely that 80-160 children treated in any one year will develop a second neoplasm or leukaemia 20 years later, most commonly as a late sequela of the treatment.

Immunoelectrophoresis of extracts of 200 intracranial tumours against rabbit anti-
glioblastoma
serum gave positive results (= precipitation) in all cases of tumours of neuroectodermal origin such as
glioblastoma
, astrocytoma, oligodendroglioma, ependymoma, neurinoma, and spongioblastoma. No immunoelectrophoretic precipitation was seen for any of the tumours of mesenchymal origin, for instance meningioma and metastases of
cancer
. On the basis of these findings, immunoelectrophoresis is considered to be a reliable method for differentiation between tumour tissue of neuroectodermal and non-neuroectodermal origin. Among the 41 posterior fossa tumours some unusual observations were made. Cerebellar angioblastoma (Lindau tumour) showed an atypically located precipitation line, which for the present is interpreted as an immunological reaction to vascular wall tissue. Furthermore, among the group of so-called medulloblastomas, two subgroups were distinguished on the basis of three parameters. The first of these subgroups comprises tumours whose immunoelectrophoretic pattern resembles that of gliomas, which are histologically characterized by neuroectodermal structures and which occur in younger children (5--10 years). The tumours of the second subgroup, which do not show this neuroectodermal immunoelectrophoretic pattern, have a sarcomatous character histologically, and occur in patients aged between 10 and 50 years. The view that medulloblastoma comprises a number of different types of tumour seems to be confirmed by this finding.

An account is given of a family from the Canton of Valais, suffering from hereditary adenocarcinomatosis. The pedigree extends over four generations; the first three comprise 47 individuals (28 males, 19 females), of whom 21 (16 males and 5 females), i.e. 44.6%, are affected with malignant tumours. Of the 32 people in the fourth generation, only one individual is affected to date (a girl aged 21, IV/14). There were 27 tumours in all: 16 adenocarcinomas of the colon, two gastric adenocarcinomas, one duodenal adenocarcinoma, one rectal adenocarcinoma, one papillary carcinoma of the ovary, one osseous sarcoma, one cutaneous fibrosarcoma, a multiform
glioblastoma
of the basal nuclei of the brain, a basocellular epithelioma, also a cerebral metastasis from an adenocarcinoma, the origin of which has not been established, and a tumour invading the biliary tract. Three members of the family suffered from multiple tumours. In three of the patients, the colonic adenocarcinoma was accompanied by one or two polyps. The average age at the onset for all the tumours was 45 years. It was definitely lower in the third than the second generation (anticipation). The transmission was autosomal dominant, with predilection for the male sex (57.1% male and 26.3% female patients). The penetrance was about 80%. The author finally discusses the diagnostic criteria for hereditary adenocarcinoma and reviews the different familial forms of
cancer
.

Surface membrane microprojections and coated vesicles of a well differentiated (Kernohan-Sayre grade I) cerebral fibrillary astrocytoma were compared with those of anaplastic astrocytic (grade IV,
glioblastoma
) cerebral tumors. Both phenomena increase with increased
malignancy
. This provides further evidence for membrane alterations with malignant change in human astrocytic cells. It is the first comparison of fibrillary astrocytoma surface phenomena with those of more malignant astrocytic tumors of the cerebrum.

The correlation existing in several human
malignancies
between lymphocytic infiltration and prolonged survival prompted this study. Two hundred selected patients who were operated on for
glioblastoma
were reviewed to investigate the incidence of the lymphocytic infiltration in the histological slides and its possible relevance to a better clinical course. The group that exhibited a definite lymphocytic infiltration (Group A, 11.5%) had a significantly longer preoperative history and postoperative survival (p less than 0.01) than the other two groups that presented slight or no infiltration (Group B, 23%, and Group C, 65%, respectively). In addition, biopsies of 28 recidivous gliomas were reviewed to study the fate of this lymphocytic infiltration in relation to time and therapy, such as irradiation and steroids which are known to depress the immune response. The authors found that severe lymphocytic infiltration is a rare immunobiological reaction which significantly improves the prognosis of a malignant brain tumor and seems not to be influenced by time, local x-ray therapy, or steroids.

Forty-three patients with inoperable and/or recurring malignant gliomas, and 30 patients with multiple recurring brain metastases were treated with a combination of adriamycine (45 mg/m2) and 4-dimethyl-epipodophyllotoxin D-thenylidene (VM 26) (60 mg/m2 for 2 days) with 1-(2-chloroethyl) -3-cyclohexyl-1-nitroso-urea (CCNU) (60 mg/m2 for two days). These cycles of treatment were repeated as soon as the hematological restoration was complete. The treatment was well tolerated and the clinical condition of 31 out of 43
glioblastoma
patients improved during the two months after the beginning of the treatment. Six out of eight patients with breast cancer metastases, one out of 13 with bronchial cancer metastases and three out of nine with other types of
cancer
metastases also benefitted from the treatment. Examination of the results obtained reveals the following characteristics: -A low degree of efficiency of the combination in the treatment of brain metastases, except for breast cancer metastases. -Absence of complete correlation between the clinical results observed and the cinegammagraphic developments. -Similarity of the results independent of the initial localization. -Establishment of a six-months median survival period, with ten patients at present in a state of apparently complete remission, 180 to 506 days after beginning of the treatment.

Sera from patients with malignant and benign gliomas, as well as sera from healthy donors, were tested by indirect immunofluorescence to detect antibodies against antigens on the membrane of
glioblastoma
, astrocytoma, reactive perimetastatic glia, normal glia and fibroblasts in tissue culture. Sera from
glioblastoma
patients reacted with
glioblastoma
, astrocytoma and reactive glial cells; they were negative on normal glia and on fibroblasts, whereas sera from astrocytoma patients were unreactive. Sera from control patients were positive in 7 out of 15 cases, although some differences were noted in the pattern of reaction. Absorption with astrocytoma powder, with
glioblastoma
and reactive glial cells indicated that all the positive cell lines expressed an astrocytoma-associated antigen "A", while only
glioblastoma
lines and reactive glial line shared a supplementary antigen "G". Neither of these 2 antigens seemed to be present in significant amount in normal brain, since the positive reactions could not be abolished by absorption with normal brain powder. The relationship between these 2 antigens and the process of increasing
malignancy
in gliomas is briefly discussed.

A rather distinct correlation in the content and distribution of DNA with the grade of
malignancy
was estabilished for the following series: normal astrocytes, and oligodendrocytes, typical astrocyfomas and oligodendrogliomas atypical astrocytomas and oligodendrogliomas. For glioblastomas this correlation is impaired, because the polymorphic variant of
glioblastoma
is characterized by particularly great disturbances in the content and distribution of DNA in the form of polyploidy and aneuploidy which, in this case, reflects not only the grade of
malignancy
, but also a pronounced polymorphism of tumour cells. The content of DNA in rapidly growing malignant tumours is not only an expressions of real deviation to the side of polyploidy and the mitotic cycle. In neuroectodermal tumours growing in the condition of cell culture, the similar regularity was observed, although the phenomena of aneuploidy were more distinctly expressed in the majority of tumours.

glioblastoma
patients improved during the 2 months after the beginning of the treatment. Six of eight patients with breast cancer metastases, one of 13 with bronchial cancer matastases, and three of nine with other types of
cancer
metastases also benefitted from the treatment. Examination of the results obtained revealed the following characteristics: 1) This combination had a low degree of efficiency in the treatment of metastases to brain, except for breast cancer metastases; 2) there was no complete correlation between the clinical results observed and the cinegammagraphic developments; 3) the results obtained were similar, independent of the initial localization; and a 6-month median survival period was established, with 10 patients now in a state of apparently complete remission, 180 to 506 days after beginning of the treatment.
