The
neuroblastoma
in the adult is a rare disease which has a bad prognosis. Until now, there are no generally accepted therapy conceptions. The clinical symptoms of the patient whose case is presented here were above all pains in the pelvic region. The histologic diagnosis was difficult and could be proved only by additional examinations of other metastases. Although the
primary tumor
was searched for intensively, is was only found 20 months later. Especially radiotherapy, but also chemotherapy (CYVADIC regimen) have proved to be effective. Above all, the quality of life could be largely maintained over a period of 26 months.

Of 42 radionuclide bone scans in 35 children with
neuroblastoma
, 21 were abnormal for the presence of skeletal metastases. Of the 21 abnormal scans, 16 were corroborated by positive bone-marrow biopsy or clinical data. The false-negative and false-positive rates for bone scanning were 4.8% and 9.5%, respectively. Calcification of the
primary tumor
was seen on pretreatment computed tomographic (CT) scans in 24 (89%) of 27 cases, while only 13 (48%) of 27 were detectable by plain radiographs. Uptake of technetium-99m methylene diphosphate (99mTc-MDP) by the
primary tumor
occurred in 20 of 27 cases, but correlation between tumor uptake and calcification was not statistically significant. All children with markedly elevated urinary vanillylmandelic acid exhibited
primary tumor
uptake. Survival was not affected independently by
primary tumor
uptake.

Sixty-six percent of 54 patients with
neuroblastoma
demonstrated uptake of bone-seeking radioagents by the
primary tumor
. This is a higher incidence than previously reported. Uptake was slightly more common in abdominal than thoracic tumors. There was a significant correlation between the size of the tumor and tracer uptake. Calcification was demonstrated in the
primary tumor
in almost 90% of the 54 patients. This is a much higher incidence of calcification than previously reported. Microscopy shows that the calcification is not always due to tumor necrosis; it also occurs in areas of viable tumor cells. Tracer uptake is believed to be related to calcium metabolism. The rate of metabolic activity rather than the total amount of calcium present within the tumor may be the most important factor in determining the amount of uptake. No significant relationship was found between tracer uptake and tumor stage or homovanillic acid and vanillylmandelic acid metabolic activity.

DNA prepared from cell lines and transplanted tumors originating from five representative types of BKV-induced hamster tumors was examined for the presence of the BKV genome by analyzing DNA/DNA reassociation kinetics. BKV DNA sequences were detected in all cases. There were only a few (1--4) copies of BKV DNA per cell in one osteosarcoma and two ventricular tumors (one choroid plexus papilloma and one ependymoma), but there were multiple (up to 150) copies in one osteosarcoma, one ventricular tumor (choroid plexus papilloma), two insulinomas, one pineocytoma, and one cerebral
neuroblastoma
. In some cases the number of copies of the viral DNA differed among sister cell clones derived from the same
primary tumor
. Apparently some tumors contained nonintegrated free viral DNA besides the integrated BKV genome.

Three enolase isozymes (alpha alpha, alpha gamma, and gamma gamma) and S-100 protein in the extract of neuroendocrine tumors (
neuroblastoma
, ganglioneuroblastoma, ganglioneuroma, and pheochromocytoma) and nonneuroendocrine tumors (Wilms' tumor, rhabdomyosarcoma, and hepatoblastoma) were determined by means of enzyme immunoassay systems. All of the tumors examined showed a high level of alpha alpha-enolase (1.71 to 19.0 micrograms/mg protein). Levels of nervous system-specific enolases (NSE; alpha gamma and gamma gamma) in the neuroendocrine tumors were also rather high (alpha gamma, 1.64 to 7.45 micrograms/mg protein; gamma gamma, 0.052 to 5.56 micrograms/mg protein). However, the NSE concentration in the extract of nonneuroendocrine tumors was low (alpha gamma, less than 0.88 micrograms/mg protein; gamma gamma, 0 microgram/mg protein). The level of S-100 protein was relatively high in ganglioneuroma (greater than 500 ng/mg protein) and ganglioneuroblastoma (greater than 100 ng/mg protein), but low in
neuroblastoma
(less differentiated neuroendocrine tumor) and nonneuroendocrine tumors. Serum levels of enolase isozymes were also determined in
neuroblastoma
patients before and after resection of
primary tumor
or effective chemotherapy. The elevated level of serum NSE (alpha gamma and gamma gamma) was markedly decreased with little change in the alpha alpha level by the treatment.

Members of children's cancer study group designed Study CCG 351 to determine whether three drug chemotherapy improved the survival experience of children with localized
neuroblastoma
. Patients in stages I-III were treated with surgical removal of the
primary tumor
and those in stages II and III received radiation therapy to the tumor bed and chemotherapy. Treatment included cyclophosphamide, imidazolecarboxamide, and vincristine given in 5-day pulses each month for 12 courses. The results were compared to those from a previous study, CCG 011, for localized
neuroblastoma
, in which children were randomized between a treatment regimen that included cyclophosphamide and one with no chemotherapy. There were 133 evaluable patients, subdivided as follows: stages I-26, stages II-74, and stages III-33. The 3-year life-table survival rates by stage of 96, 89 and 50% were not significantly different from the patients in CCG 011 similarly staged who received either no chemotherapy or oral CPM. These data suggest that multiagent chemotherapy, as prescribed, did not improve the outlook for children with locally advanced but nonmetastatic
neuroblastoma
. The staging criteria employed showed a modest difference in outcome between patients in stages I and II, but a significant poorer survival for stage III as compared to either stage I or II.

The results of 112 children with
neuroblastoma
treated at the Memorial Sloan-Kettering Cancer Center between 1949 and 1980 were analyzed. Of these children, 58 were 0-11 months old and 54 were 12-23 months old and there was a median follow-up of 111 months. All 10 patients with Stage I are alive, 21/27 with Stages II and III (78%) are alive, 5/67 patients (7%) with Stage IV are alive, and 7/8 patients with Stage IVS are alive. Age of the children is an independent prognostic factor. The survival of infants with Stage IV is significantly better than it is for older children of the same stage. Two of 15 infants in Stages II and III died, both of early complications, whereas 4/12 older children with the same stages died. Minimal individualized treatment is recommended for children 0-11 months old who have localized and Stage IVS
neuroblastoma
. Children less than 1 year old with localized and Stage IVS
neuroblastoma
had an extremely good prognosis (90% survival) and were usually cured without intensive chemotherapy. Surgical removal of the
primary tumor
was sufficient for Stage I, and partial tumor removal followed by conservative radiation or chemotherapy was sufficient in most Stage II and III patients. Gentle, individualized treatment was adequate for Stage IVS. Children less than 1 with Stage IV
neuroblastoma
had a significantly better prognosis than older children of the same stage, but their prognosis was still poor (18% survival).

Tumor samples, obtained from a single patient at two points in his illness, have enabled us to study clonal evolution in a
neuroblastoma
. Cells from the
primary tumor
demonstrated considerable heterogeneity in terms of chromosome number; cells from 4 subsequent metastases were all nearly diploid; and cells from a tumor produced in a mouse by the injection of cells from the
primary tumor
were hypotriploid in modal number. All of the tumor samples contained the same marker chromosome rearrangements, indicating their origin from a common precursor. Each of the cell lines analyzed (including those from the patient's metastases, those from the tumor in a mouse, and those from the
primary tumor
after 11 months in continuous culture) also contained different and distinguishing chromosome abnormalities. The differences in karyotype among these tumor samples and cell lines presumably reflect the different selection pressures at work in each instance.

Sonograms of 21 children with
neuroblastoma
were reviewed with attention to the following sonographic criteria: size, location, internal echo pattern, anechoic areas, and margination. Fourteen primary tumors were evaluated before therapy. All tumors were heterogeneously echogenic; all had poorly defined margins. Tumor calcification was identified in three, and 10 of 14 primary tumors contained discrete anechoic areas ranging from 0.5 to 4 cm in diameter. The average greatest dimension of
primary tumor
masses was 7.7 cm.

The authors considered 59 stage III and IV
neuroblastoma
cases, which were observed from January 1967 to June 1979. 13 patients (13/59 = 22%) are surviving in complete remission 3 years after surgery: 9/20 (45%) with stage III and 4/39 (10%) with stage IV disease. The children subjected to complete surgical excision are all alive irregardless of age; the children who were not operated on or subjected to a biopsy, have all died. Of the 33 patients who underwent a reductive excision, 6 (all under 2 years of age) are in complete remission (18%). A better prognosis was found in those patients in whom the site of the
primary tumor
was at the mediastinal level. These data show the importance of the role of the surgeon in the multidisciplinary treatment of stage III and IV neuroblastomas; our experience is also favorable to the practice of second-look surgery.
