Abstract
Pineal region tumors fall into five broad categories: benign pineal region tumors, glial tumors, papillary tumors, pineal parenchymal tumors, and germ cell tumors. Genetic and transcriptional studies have identified key chromosomal alterations in germinomas (RUNDC3A, ASAH1, LPL) and in pineocytomas/pineoblastomas (DROSHA/DICER1, RB1). Pineal region tumors generally present with symptoms of hydrocephalus including nausea, vomiting, papilledema, and the classical Parinaud's triad of upgaze paralysis, convergence-retraction nystagmus, and light-near pupillary dissociation. Workup requires neuroimaging and tissue diagnosis via biopsy. In germinoma cases, diagnosis may be made based on serum or CSF studies for alpha-fetoprotein or beta-HCG making the preferred treatment radiosurgery, thereby preventing the need for unnecessary surgeries. Treatment generally involves three steps: CSF diversion in cases of hydrocephalus, biopsy through endoscopic or stereotactic methods, and open surgical resection. Multiple surgical approaches are possible for approach to the pineal region. The original approach to the pineal region was the interhemispheric transcallosal first described by Dandy. The most common approach is the supracerebellar infratentorial approach as it utilizes a natural anatomic corridor for access to the pineal region. The paramedian or lateral supracerebellar infratentorial approach is another improvement that uses a similar anatomic corridor but allows for preservation of midline bridging veins; this minimizes the chance for brainstem or cerebellar venous infarction. Determination of the optimal approach relies on tumor characteristics, namely location of deep venous structures to the tumor along with the lateral eccentricity of the tumor. The immediate post-operative period is important as hemorrhage or swelling can cause obstructive hydrocephalus and lead to rapid deterioration. Adjuvant therapy, whether chemotherapy or radiation, is based on tumor pathology. Improvements within pineal surgery will require improved technology for access to the pineal region along with targeted therapies that can effectively treat and prevent recurrence of malignant pineal region tumors.

Abstract
Background: The pineal gland, a small, pinecone-shaped organ deep within the brain, is responsible for producing melatonin. The gland consists of pineal parenchymal cells and glial cells that can form neoplasms. Pineal region neoplasms can also arise from germ cells and adjacent structures. This review focuses on detection of serum and cerebrospinal fluid (CSF) biomarkers of germ cell tumors and pineal parenchymal cell tumors, as these types comprise most neoplasms specific to the pineal region. Methods: For this review, we searched PubMed using the following keywords: biomarkers, germ cell tumor, germinoma, melatonin, pineal, pineal gland, pineal neoplasm, pinealoma, pineal parenchymal cell tumor, pineal region, and pineal tumor. We limited our search to full-text English articles and identified other relevant sources from the reference lists of identified articles. Results: Serum and CSF biomarker assays have a role in cases of suspected pineal germ cell or parenchymal neoplasms. Biomarkers including alpha-fetoprotein, beta-human chorionic gonadotropin, and placental alkaline phosphatase inform diagnosis and treatment and are important for monitoring germ cell tumor response to treatment. No biomarkers are currently available that inform diagnosis or treatment of pineal parenchymal tumors, although melatonin assays may have a role in monitoring response to treatment. Conclusion: Serum and CSF biomarkers in conjunction with clinical and radiographic evidence of a pineal region mass can inform the decision whether to undertake stereotactic biopsy or surgical excision or whether to proceed straight to medical treatment.

Abstract
Thirteen patients with tumors in the pineal region were submitted to pre- and post-operative blood sampling (08:00, 14:00, 20:00, and 02:00 hr) for three or four consecutive days. A single cerebrospinal fluid (CSF) sample was collected at surgery, and melatonin levels determined. In all patients, serum and CSF beta subunit of human chorionic gonadotrophin (betaHCG), carcino embryonic antigen (CEA), and alpha-fetoprotein (AFP) levels were measured. Histology revealed four pineocytomas, one pineoblastoma, four germinomas, one immature teratoma, one pilocytic astrocytoma, one lymphoma, and one meningioma. Serum and CSF levels of serological biomarkers were normal, except for one of the germinoma cases. In most patients, alteration either in the circadian rhythm or in the melatonin concentration was observed before surgery. In benign neoplasms the circadian rhythm was conserved. In pineoblastoma, lymphoma, and three out of four germinomas, melatonin concentrations were undetectable. In one case of germinoma, melatonin levels were high, with the circadian rhythm being abolished. According to conventional histology, all germinomas were similar. Therefore, in a rare case of pineal germinoma with high melatonin levels, the tissue was subjected to an in depth investigation (immunohistochemical and ultrastructural) in order to determine the pathology and the possible differences from the other typical germinomas. Results were compared to those provided from other pineal neoplasms. Electron microscopy examination detected the presence of clusters of intermediate filaments and numerous electrondense granules only in the case of a germinoma producing melatonin.

Abstract
This investigation evaluated the possibility that the occurrence of S-antigen in cerebrospinal fluid (CSF) might be used as a preoperative marker of pineal parenchymal tumors (pineoblastoma and pineocytoma). Such a marker could provide a means of preoperatively differentiating these neoplasms from pineal region tumors of other origin. The S-antigen, also known as the 48-kD protein or arrestin, is a highly antigenic protein originally found in the retina and pineal gland. In the retinal photoreceptors and submammalian pineal photoreceptors the protein is thought to be involved in phototransduction; its function in the mammalian pinealocyte is unknown. S-Antigen immunoreactivity also occurs in certain neoplastic cells of retinoblastomas, pineocytomas, pineoblastomas, and cerebellar medulloblastomas. This study included a group of 13 patients with tumors of the pineal region. Samples of CSF were obtained preoperatively and analyzed for the S-antigen using western blot technology. Tumor biopsy material was classified according to conventional neurohistological criteria and was also examined by immunocytochemical techniques for the presence of the S-antigen. S-Antigen immunoreactivity was found in the preoperative CSF of the one patient found to have pineocytoma; tumor tissue removed from this patient was the only neoplastic tissue examined in this study which contained S-Antigen immunoreactive tumor cells. Furthermore, hydroxyindole-O-methyltransferase activity was detectable in the pineocytoma but not in three other pineal tumors, and melatonin levels in the CSF of the pineocytoma patient were the highest in the patient group examined. These preliminary results suggest that testing for S-antigen in CSF might be useful in characterizing and treating tumors of the pineal region and, when identified in conjunction with other markers, it might also help to better define pineal parenchymal tumors. This study needs confirmation with a larger number of patients. If this approach is eventually found to be a reliable predictor of pineal cell tumors, it may supplant the need for surgical biopsies before initiating appropriate adjunctive therapy.

Abstract
The natural history of primary intracranial germ-cell tumors (GCT's) is defined from 389 previously published cases, of which 65% were germinomas, 18% teratomas, 5% embryonal carcinomas, 7% endodermal sinus tumors, and 5% choriocarcinomas. Intracranial GCT's display specificity in site of origin. Ninety-five percent arise along the midline from the suprasellar cistern (37%) to the pineal gland (48%), and an additional 6% involve both sites. The majority of germinomas (57%) arise in the suprasellar cistern, while most nongerminomatous GCT's (68%) preferentially involve the pineal gland (p less than 0.0001). The age distribution of afflicted patients is unimodal, centering with an abrupt surge in frequency in the early pubertal years; 68% of patients are diagnosed between 10 and 21 years of age. Nongerminomatous GCT's demonstrate an earlier age of onset than do germinomas (p less than 0.0001). Prolonged symptomatic intervals prior to diagnosis are common in germinomas (p = 0.0007), in suprasellar GCT's (p = 0.001), and among females (p = 0.02). Parasellar germinomas commonly present with diabetes insipidus, visual field defects, and hypothalamic-pituitary failure. Nongerminomatous GCT's present as posterior third ventricular masses with hydrocephalus and midbrain compression. Germ-cell tumors may infiltrate the hypothalamus (11%), or disseminate to involve the third ventricle (22%) and spinal cord (10%). Among a subpopulation of 263 conventionally treated patients, two factors were of prognostic significance: 1) histological diagnosis; germinomas were associated with significantly longer survival than nongerminomatous GCT's (p less than 0.0001); and 2) staging of the extent of disease; this emphasizes the ominous character of involvement of the hypothalamus (p = 0.0002), third ventricle (p = 0.02), or spinal cord (p = 0.01). Specific recommendations regarding the necessity of histological diagnosis and staging of the extent of disease are made in light of modern chemotherapeutic advances. The pathogenesis of GCT's may be revealed by their specificity of origin within the positive (suprasellar cistern-suprachiasmatic nucleus) and negative (pineal) regulatory centers for gonadotropin secretion within the diencephalon. The abrupt rise in age distribution at 10 to 12 years suggests that the neuroendocrine events of puberty are an "activating" influence in the malignant expression of these embryonal tumors.

Abstract
Autopsy series of 19 patients with pineal and anterior third ventricle (suprasellar) tumors were analyzed with regard to shift in pituitary-adrenal axis. Germinomas formed the most common subgroup in this series (79%). Metastatic tumor growth in the pituitary gland caused adrenal atrophy in 4 cases. Some patients with pineal neoplasms had larger adrenals in weight compared with age- and sex-matched controls of Japanese. In three patients with sexual precocity, adrenal weight was larger. It is concluded that clinical importance exists in anterior pituitary insufficiency with adrenal atrophy, but hyperfunction of the hypophyseoadrenal system might occur during the course of the disease.

Abstract
Melatonin in chloroform extracts of timed overnight urine collections was measured by radioimmunoassay. Melatonin excretion was determined in 88 boys and 82 girls 9-16 yr of age, in 16 adult males, and throughout the menstrual cycle of one adult female. By succeeding age groups (9-10.9, 11-12.9, 13-14.9, and 15-16.9 yr) boys showed a progressive increase in mean +/- SD melatonin excretion from 3.0 +/- 1.3 ng/hr for the 9-10.9 yr age group to 9.8 +/- 2.8 ng/hr for the 15-16.9 yr age group. The girls' excretion increased for the 11-12.9 yr age group (9-10.9 versus 11-12.9 = 4.0 +/- 2.3 versus 6.1 +/- 2.7 ng/hr, p less than 0.005), plateaued for the 13-14.9 yr age group (5.8 +/- 3.3 ng/hr, p greater than 0.3), and decreased for the 15-16.9 yr age group (2.0 +/- 1.4 ng/hr, p less than 0.005). Subjects with initial signs of puberty as compared to prepubertal subjects had increased melatonin excretion (boys, 4.7 +/- 1.4 versus 2.4 +/- 0.9 ng/hr; girls 5.7 +/- 1.9 versus 2.4 +/- 0.9 ng/hr, p less than 0.005). Excretion of the adult males (1.6 +/- 1.1 ng/hr) was less (p less than 0.005) than that of boys of all age groups. At the time of menstrual bleeding melatonin excretion was elevated; peak excretion (15.5 ng/hr) occurred 3 days prior to the midcycle gonadotropin surge. Follicular phase (10.7 +/- 2.9 ng/hr) excretion was (p less than 0.005) greater than luteal phase (4.2 +/- 1.1 ng/hr) excretion. These data show that melatonin excretion increases when the initial signs of puberty are present. This finding is inconsistent with an inhibitory influence of melatonin on pubertal development. Gonadal function may influence melatonin secretion during puberty and melatonin may play a role in adrenarche.

Abstract
Seventeen patients wih pineal tumors and one ectopic (suprasellar) germinoma were treated with radiation therapy. Surgery was restricted to decompression in 16 patients, and only two patients had resection of the tumor. Thirteen of 18 patients are alive without evidence for disease with a ten-year survival rate of 88%. The tumor dose ranged from 4000 rads to 6000 rads. No age or dose dependence in survival was noted, but patients with whole brain irradiation or generous volume to include ventricular system had better survival. No case of spinal metastasis was noted. The possibility of increased incidence of meningeal seeding following surgical intervention is considered. From their data, the authors feel that radiation therapy with or without surgical decompression should be the primary treatment for pinealoma. Surgery can be used for diagnosis and/or treatment of patients who show delayed response to radiation. Recommendation is made for the use of whole brain irradiation to 4000 rads followed by a boost to the tumor area to 5000 rads.

Abstract
Our knowledge of pineal neoplasms is still fragmentary, but a pattern is beginning to emerge in this highly challenging area of neuro-oncology. In vitro studies and more complete morphologic and biochemical characterization are still needed for these very rare neoplasms. Follow-up data from appropriate clinical series are still almost nonexistent for the evaluation of therapeutic effectiveness. As an illustration of neoplastic development, the demonstration of divergent differentiation in pineal parenchymal tumors represents a most intriguing phenomenon in light of the origin, structure, and function of the pineal gland.

Abstract
Pathologic survey was performed on 43 cases of intracranial germinoma and 12 cases of pinealoma. The present study suggests that, in Japan, the incidence of teratoma groups including germinoma is remarkably higher than that in U.S. and Europe, whereas the rate of true pinealoma is lower. Using ultrastructural, enzyme-histochemical, and fluorescence-histochemical methods for a few surgical specimens, a strong similarity between intracranial germinoma (so-called "pinealoma" with a two-cell pattern) and seminoma and dysgerminoma was confirmed. The true pinealoma could be classified as pineoblastoma and pineocytoma, according to the degree of pineocyte differentiation of the tumor cells, and as "neuroblastoma-like" and "pineal-like" on the basis of the histologic architecture.

Bacteriol. 92:28-34. 1966.-Thirty-seven strains from the genera Micrococcus, Staphylococcus, Gaffkya, and Sarcina were examined for deoxyribonucleic acid base composition and biochemical activity. Organisms were tested for production of catalase, coagulase, deoxyribonuclease, oxidase, phosphatase, hydrogen sulfide, indole, and acetoin; nitrate reduction; gelatin, starch, and urea hydrolysis; citrate and ammonium phosphate utilization; NaCl tolerance; growth at 10 and 45 C, and growth in litmus milk. They were tested for production of acid from dextrose and mannitol under anaerobic conditions, and for aerobic production of acid from dextrose, mannitol, lactose, sucrose, raffinose, maltose, xylose, and glycerol. Organisms could be divided into two groups on the basis of guanine-cytosine (GC) content. Group I had an average GC content of 32%, and included all organisms which produced acid from dextrose. Group II had an average GC content of 62%, and included those organisms incapable of producing acid from dextrose under anaerobic conditions. Sarcina ureae had a GC content of 43%.
