History of the Journal of Neurosurgery, 1965-1980.

The author, who was editor of the Journal of Neurosurgery from 1975 to 1985, recalls the history of the journal during the 15 hears beginning in 1965, when Dr. Louise Eisenhardt resigned as its first editor. In an addendum, he presents some thoughts on the future of neurosurgery and the role the journal should play in it.

Barnes Hospital and the Washington University Medical Center.

The author documents the development of the Medical School at Washington University since 1891, when the St. Louis Medical College was first included as part of the University. In 1909, Robert Brookings, President of the Corporation of Washington University, acquired a large endowment and moved the clinical and hospital facilities to a new location, enabled by the estate of Robert Barnes. Harvey Cushing was offered the chair of surgery but eventually decided in favor of Harvard University in 1910. Dr. Ernest Sachs was recruited to Washington University by Dr. Fred Murphy, and in 1919 became the first ever Professor of Neurological Surgery. The history of neurosurgery and those who served it at the Washington University Medical Center and Barnes Hospital is recounted.

Prognostic factors and results of therapy for adult thalamic and brainstem tumors.

This report is a retrospective analysis of 83 adults (greater than 16 years of age) with histologically proven or presumed primary neoplasms of the thalamus, hypothalamus, midbrain, pons, and medulla. Patients were treated with combined surgery and postoperative irradiation or with irradiation alone at the Washington University Medical Center (St. Louis, MO) from January 1950 through December 1984. Histologic analysis confirmed the diagnosis of tumor in 21, including nine with well-differentiated astrocytoma, four with astrocytoma with anaplasia, and eight with glioblastoma multiforme. Overall and disease-free survivals at 5 years were 28.7 and 23.2%, respectively. A statistical analysis was performed to ascertain the prognostic importance of the following variables: age, race, gender, duration of symptoms, cranial nerve paresis, primary site, extent of surgery, histology, and irradiation dose. The only factor identified by univariate analysis to be critical for survival was primary location of disease. Patients with supratentorial (thalamus/hypothalamus, midbrain) tumors had a 10-year disease-free survival of 15.4% compared to 29.6% for those with infratentorial (pons, medulla) tumors (P = 0.07). Patients with lesions of the pons had a 5-year disease-free survival of 35.8% compared to 13.8% for those with tumors of the thalamus (P = 0.05). Increasing irradiation dose was not correlated with superior survival. Factors evaluated but established to be insignificant were age (P = 0.27), race (P = 0.63), gender (P = 0.27), duration of symptoms (P = 0.19), cranial nerve paresis (P = 0.71), histologic type (P = 0.16), and extent of surgery (P = 0.94). Follow-up for 13 surviving patients ranged from 2.6 to 28.7 (mean, 12.0) years. Neurologic deficits in surviving patients were absent in 15% (two of 13), mild in 62% (eight of 23), and moderate in 23% (three of 13). One case of brain radionecrosis was identified (6000 cGy, 200 cGy daily).

Prognostic factors and results of surgery and postoperative irradiation in the management of pituitary adenomas.

Prognostic factors and results of therapy were analyzed in a retrospective examination of 121 patients with pituitary adenomas treated with surgery and postoperative irradiation (RT) from January 1954 through December 1982 at the Radiation Oncology Center, Mallinckrodt Institute of Radiology. The 10-year overall and disease-free survival for all patients was 85.1 and 89.4%. The expected survival for an age-, gender-, and race-matched population was not significantly distinct at 85.3% (p = 0.72). Follow-up of 94 surviving patients ranged from 3.4 to 29.5 years (mean, 11.7). Statistical analysis was performed for multiple prognostic factors including age, race, gender, disease bulk, visual field symptoms, disease type, surgical approach, and irradiation dose and volume. The only prognostic variable identified by univariate analysis to significantly alter disease-free survival was irradiation dose. Patients receiving 5000-5400 cGy had a tumor control rate of 94.1% (64/68) compared to 85.0% (17/20) for 4000-4999 cGy, 75.0% (18/24) for 3000-3999 cGy, and 28.6% (2/7) for less than 3000 cGy (p = 0.000059). Factors evaluated but established to be insignificant were age, race, gender, disease bulk, visual field symptoms, disease type, surgical approach, and irradiated volume. The 10-year disease-free survival by classification was 93.3% for patients with amenorrhea/galactorrhea, 89.9% for non-functioning adenomas, and 76.4% for acromegaly (p = 0.21). Overall improvement in visual field defects subsequent to treatment occurred in 48.4% (44/91) of those with visual field defects before RT and was significantly correlated with RT dose. The median time to progression of disease was 10.2 years with the last failure occurring at 25 years following the fulfillment of RT. Severe complications related to RT were apparent in 1.7% (2/121). None were known to have endured brain radionecrosis. Serious surgical complications occurred in 9.9% (12/121).

Multivariate analysis of prognostic factors in pediatric and adult thalamic and brainstem tumors.

A multivariate analysis of prognostic variables was performed on a retrospective review of 136 patients with presumed or histologically proven primary lesions of the thalamus and brainstem treated by combined surgery and post-operative irradiation or by irradiation alone from January 1950 through December 1983. Overall survival for all patients at 5 and 10 years was 34.4 and 27.8%, respectively. Follow-up of 33 living patients ranged from 3 to 22 years. Prognostic variables analyzed by univariate analysis and found to be of significance (p less than 0.05) were race, duration of symptoms, extent of surgery (i.e. subtotal excision), and dose of irradiation. Further evaluation by Cox regression analysis revealed these same factors to be of prognostic significance (p less than 0.05). It is of importance to note that age and tumor site were not significant prognostic variables in the multivariate analysis but were significant by univariate analysis. The 5-year overall survival for patients with thalamic tumors was 59.5 and 20.9% for children and adults, respectively (p = 0.006). The 5-year overall survival for patients with pontine lesions was 46.6 and 16.0% for adults and children, respectively (p = 0.01). Only one patient was known to have expired due to a complication of therapy. Neurologic deficits and functional ability was normal or mild in 57.6% of the surviving patients.

Irradiation of primary thalamic and brainstem tumors in a pediatric population. A 33-year experience.

A retrospective analysis of 70 pediatric patients (less than 16 years of age) with histologically proven or presumed primary neoplasms of the thalamus, hypothalamus, and brainstem, treated with combined surgery and postoperative radiotherapy or radiotherapy alone at the Washington University Medical Center from January 1950 through December 1983, is reported. Overall survival for all patients at 5 and 10 years was 34.9% and 32.7%, respectively. Follow-up of the 22 surviving patients ranged from 3.0 to 20.0 years (median, 10.6 years). Statistical analysis of multiple prognostic factors was performed. Prognostic factors found by single variate analysis to significantly influence survival were primary site of disease, extent of surgery, race, cranial nerve paresis at diagnosis, and dose of radiation. Factors evaluated but found to be insignificant were age at diagnosis, duration of symptoms before diagnosis, sex, and volume irradiated. Multivariate analysis revealed that only total radiation dose and race were of prognostic significance.

CA 19-9 and CA 125 levels in the sera of normal blood donors in relation to smoking history.

CA 19-9 and CA 125 serum levels were evaluated among smoking and nonsmoking healthy blood donors. Smoking did not elevate mean levels of either CA 19-9 or CA 125 in the sera of 496 of these blood donors from Philadelphia, PA. Mean CA 19-9 levels were slightly higher among females than among males. Among smokers there was a trend toward slightly increasing CA 19-9 serum levels with increased age, which was significant among the male donors. Trends toward slightly decreased mean serum levels of CA 125 among smokers were of borderline significance. Serum CA 19-9 and CA 125 levels in none of these donor subpopulations was elevated compared to levels reported by others for gastrointestinal or ovarian carcinoma patients, respectively. Therefore, smoking status should not interfere with use of either the CA 19-9 or CA 125 assays for diagnostic or monitoring applications.

The surgical correction of coronal and metopic craniosynostoses.

Procedures for relief of coronal synostosis and metopic synostosis have resulted in some undesirable sequelae. The authors present combined neurological and plastic surgical modifications to prevent additional synostoses, forehead ridging, and lateral orbital wall step-off. They recommend bifrontal craniotomy with lateral wall osteotomy into the body of the zygoma and self-retaining grafts.

Atrial myxoma with intellectual decline and cerebral growths on CT scan.

A woman with left atrial myxoma had progressive disturbance of intellectual function, headache, and prominent constitutional symptoms. The absence of stroke is noteworthy. Multiple high-density lesions with contrast enhancement were seen by CT scan, suggesting metastatic neoplasms, hematomas, or hemorrhagic infarcts. Serial study showed progressive enlargement of the lesions. The only cerebral lesion examined histologically proved to be an organizing hematoma, originating most likely from adjacent small arteries found to be plugged by embolic myxoma.
