Abstract
Pineal parenchymal tumors are rare central nervous system tumors that pose diagnostic challenges for surgical pathologists. Due to their paucity, their clinicopathologic features are still being defined. We report an 86-year-old woman with a remote history of breast lobular carcinoma who presented with a 2-month neurologic history that included gait instability, blurry vision, and headaches. Magnetic resonance imaging revealed a lobular, heterogeneously enhancing pineal region mass compressing the aqueduct of Sylvius. A biopsy performed concomitant with endoscopic third ventriculostomy consisted of small sheets of cells with eosinophilic to clear cytoplasm, multipolar processes, and ovoid nuclei with stippled chromatin. Whole exome sequencing revealed a small in-frame insertion (duplication) in exon 4 of KBTBD4 (c.931_939dup, p.P311_R313dup/ p.R313_M314insPRR), which has very recently been reported in 2 pineal parenchymal tumors of intermediate differentiation (PPTID). Additionally, variants of uncertain significance in CEBPA (c.863G > C, p.R288P) and MYC (c.655T > C, p.S219P) were identified. Although PPTID is considered a disease of young adulthood, review of 2 institutional cohorts of patients with pineal region tumors revealed that 25% of individuals with PPTID were over 65 years of age. In conclusion, PPTID should be considered in the differential diagnosis of pineal region tumors in older adults.

Abstract
BACKGROUND Pineal tumors are rare, and the pineal region is a challenging surgical location for neurosurgeons. The present study aimed to investigate the effects of microsurgical management in patients with pineal region tumors and explore probable factors associated with preoperative hydrocephalus, postoperative hydrocephalus remission, and prolonged hospital length of stay (LoS). METHODS A retrospective study of patients with pineal region tumors who underwent microsurgical management at the First Affiliated Hospital of Soochow University (Jiangsu, China) between 1 January 2010 and 31 October 2022 was conducted. RESULTS Data from 36 patients were included in this study. The top 5 common symptoms included headache (58%), dizziness (44%), double vision (22%), vomiting (19%), and nausea (14%). Patients with a lower Karnofsky Performance Score (KPS), younger age, and larger maximum tumor diameters were more vulnerable to preoperative hydrocephalus. Preoperative hydrocephalus also led to a prolonged postoperative LoS (P = 0.021). Patients with a lower KPS score (P = 0.020) or larger maximum tumor diameters (P = 0.045) were more likely to achieve postoperative remission of hydrocephalus. Most postoperative complications led to increased hospital LoS. CONCLUSIONS Microsurgical resection of pineal tumors yielded favorable long-term outcomes. Patients with a lower KPS score, younger age, and larger maximum tumor diameters were more vulnerable to preoperative hydrocephalus and prolonged LoS. Patients with a lower KPS score or larger tumor diameter were likely to achieve significant remission of hydrocephalus after tumor resection.

Abstract
INTRODUCTION Pineal region tumors have historically been challenging to treat. Advances in surgical techniques have led to significant changes in care and outcomes for these patients, and this is well demonstrated by our single institution's experience over a 17-year-period in which the evolution of diagnosis, treatment, and outcomes of pineal tumors in pediatric patients will be outlined. METHODS We retrospectively collected data on all pediatric patients with pineal region lesions treated with surgery at Children's National Hospital (CNH) from 2005 to 2021. Variables analyzed included presenting symptoms, presence of hydrocephalus, diagnostic and surgical approach, pathology, and adverse events, among others. IRB approval was obtained (IRB: STUDY00000009), and consent was waived due to minimal risk to patients included. RESULTS A total of 43 pediatric patients with pineal region tumors were treated during a 17-year period. Most tumors in our series were germinomas (n = 13, 29.5%) followed by pineoblastomas (n = 10, 22.7%). Twenty seven of the 43 patients (62.8%) in our series received a biopsy to establish diagnosis, and 44.4% went on to have surgery for resection. The most common open approach was posterior interhemispheric (PIH, transcallosal) - used for 59.3% of the patients. Gross total resection was achieved in 50%; recurrence occurred in 20.9% and mortality in 11% over a median follow-up of 47 months. Endoscopic third ventriculostomy (ETV) was employed to treat hydrocephalus in 26 of the 38 patients (68.4%) and was significantly more likely to be performed from 2011 to 2021. Most (73%) of the patients who received an ETV also underwent a concurrent endoscopic biopsy. No difference was found in recurrence rate or mortality in patients who underwent resection compared to those who did not, but complications were more frequent with resection. There was disagreement between frozen and final pathology in 18.4% of biopsies. CONCLUSION This series describes the evolution of surgical approaches and outcomes over a 17-year-period at a single institution. Complication rates were higher with open resection, reinforcing the safety of pursuing endoscopic biopsy as an initial approach. The most significant changes occurred in the preferential use of ETVs over ventriculoperitoneal shunts. Though there has been a significant evolution in our understanding of and treatment for these tumors, in our series, the outcomes for these patients have not significantly changed over that time.

Abstract
BACKGROUND A pineal region tumor is a rare intracranial tumor, and its specific location leads to its own characteristics. This study aimed to provide some insight for medical practice in the care of pineal region tumors. We investigated the key epidemiological characteristics and survival prognosis of pineal tumors based on the epidemiological data from the Surveillance, Epidemiology, and End Results database. METHODS Data of pineal region tumor patients from 1975 to 2019 were extracted from the Surveillance, Epidemiology, and End Results database. The data were divided into 3 pathologic groups: germ cell tumors, pineal parenchymal tumors, and other. The patients' overall survival (OS) was analyzed using the Kaplan-Meier method. The prognostic effects of the patient characteristics on OS were explored using the Cox proportional hazard model. The analysis results are presented as tabular data, Kaplan-Meier plots, forest plots, and nomograms. A calibration curve was used to verify the nomograms. All analyses were performed for all patients overall and stratified by pathological group using SPSS and R language. RESULTS Based on the predefined inclusion and exclusion criteria, 628 patients were included in this study, of whom 440 (70.1%) were male and 188 (29.9%) were female. Most patients were aged 0-19 years. The pathological type was germinoma for 225 patients (35.8%). Age, surgery, behavioral code, and pathology were significant factors for OS. A calibration curve was used to verify that the nomograms had a good prediction effect. CONCLUSIONS An intuitive nomogram was developed and verified and can predict the prognosis of patients with pineal tumors.

Abstract
OBJECTIVE To assess the efficacy and surgical outcomes of the simultaneous single-trajectory endoscopic biopsy and third ventriculostomy (ETV) in pineal region tumors. METHODS A systematic review and meta-analysis adhering to Cochrane Standards and PRISMA framework were conducted. PubMed, Embase, and Web Of Science databases were searched until December 2023. Outcomes included rate of histopathologic diagnosis success, ETV success, complications, required VPS, and mortality. RESULTS Seventeen studies (N = 388) met inclusion criteria. Histopathologic diagnosis success rate was 90% for general population (95% CI: 86%-95%; I2 = 42%) and 94% for pediatric patients (95% CI: 89%-98%; I2 = 19%). ETV Success rate was 93% (95% CI: 88%-97%; I2 = 60%). An estimated risk of postoperative ETV complications was found to be 16% for the general population (95% CI: 5%-28%; I2 = 90%) and 5% for pediatric patients (95% CI: 0%-13%; I2 = 51%). The risk of requiring VPS was estimated as 2% (95% CI: 0%-4%; I2 = 39%) and for the pediatric population it was 7% (95% CI: 0%-16%; I2 = 69%). Mortality risk was found to be 1% (95% CI: 0%-3%; I2 = 0%). CONCLUSIONS Simultaneous endoscopic biopsy and ETV demonstrated high diagnostic and therapeutic success rates. The procedure's safety profile, with low mortality and complications, supports its role in treating hydrocephalus associated to pineal region tumors. Subgroup analyses revealed higher diagnostic success rates and required VPS in the pediatric population, whilst it had lower complication rates.

Abstract
PURPOSE Pineal region tumors (PRT) represent less than 1% of brain neoplasms. The rare and heterogeneous nature of these tumors is reflected in the variety of treatment modalities employed. METHODS A single-center retrospective review of all pediatric patients with pineal region tumors between November 1996 and June 2021 was performed. Fifty-six cases of pineal tumors were reviewed for age and symptoms upon presentation, diagnostic methods, imaging characteristics, histological classification, treatment modalities, recurrence, and mortality rates. RESULTS The average age at diagnosis was 11.3 years. The majority of patients were male (82.1%) and Caucasian (73.2%). The most common presenting symptoms were headache (n = 38, 67.9%) and visual problems (n = 34, 60.7%). Hydrocephalus was present in 49 patients (87.5%). Germinoma (n = 20, 35.7%) and non-germinomatous germ cell tumor (NGGCT) (n = 17, 30.4%) were the most common tumors. Chemotherapy was employed for 54 patients (96.4%), radiation for 49 (87.5%), and surgical resection for 14 (25.0%). The average duration of treatment was 5.9 months. Progression-free survival was 74.4% at 5 years and 72.0% at 10 years. Overall survival was 85.7% at 5 years and 77.1% at 10 years. CONCLUSION Treatment of pineal region tumors must be targeted to each patient based on presentation, subtype, presence of hydrocephalus, and extent of disease. Upfront surgical resection is usually not indicated. As advances in oncological care proceed, treatment modalities may continue to improve in efficacy.

Abstract
BACKGROUND Pineal parenchymal tumors are exceedingly rare, and optimal disease management has yet to be defined. In this study, we aimed to identify prognostic factors and establish a predictive model for the prognosis of patients with pineal parenchymal tumors. METHODS All patients with pineal parenchymal tumors in the Surveillance, Epidemiology and End Results database between 1975 and 2019 were reviewed. Data were summarized, and survival was modeled with Cox regression analyses. In addition, a nomogram predicting 5- and 10-year survival probability for pineal parenchymal tumors was developed and validated. RESULTS We found 691 pineal parenchymal and 1961 pineal region neoplasms during 1975 and 2019 resulting in an incidence of 35%. In total, 441 patients were excluded due to incomplete data. The final cohort was subdivided into groups based on tumor histology: pineocytomas, pineoblastomas, and pineal parenchymal tumors of intermediate differentiation. Multivariate Cox analysis identified age and beam radiation as prognostic factors in pineoblastomas. Age, histology, tumor size, extent of resection, radiation, and chemotherapy were selected to build a clinical nomogram. The C-index for the nomogram was 0.795 (95% confidence interval 0.738-0.852). The calibration curves of the 5- and 10-year survival rates showed good agreement between the nomogram predictions and actual observations. CONCLUSIONS This nomogram is a convenient and precise tool for clinicians to evaluate prognosis of pineal parenchymal tumors.

Abstract
Pineal germinomas can be very complex in terms of presentation, diagnosis, and management. This review attempts to simplify this complexity in an organized manner, addressing the anatomic relationships that provide the basis for the uniqueness of pineal germinoma. Ocular findings and signs and symptoms of elevated intracranial pressure are the keys to suspecting the diagnosis and obtaining the necessary imaging and cerebrospinal fluid studies. Other symptoms can suggest spread beyond the pineal region. Surgery may only be needed to obtain tissue for a definitive diagnosis, as germinoma is highly responsive to chemotherapy and focused radiation therapy. Hydrocephalus, usually related to tumor obstruction of the cerebral aqueduct, may also need to be addressed. Outcome for pineal germinoma is usually excellent, but relapse can occur and may require additional intervention. These issues are detailed in this review.

Abstract
Simple Summary Pineal region tumors are rare intracranial tumors. A deeper knowledge of these tumors’ molecular mechanisms has been gained in recent years, which has led to a new classification and new potential systemic treatments. Surgery remains the mainstay of treatment, while radiotherapy and systemic therapy depend on histological, molecular, and clinical characteristics. This paper highlights recent developments in the diagnosis and treatment of these tumors. Abstract Pineal region tumors are rare intracranial tumors, accounting for less than 1% of all adult intracranial tumor lesions. These lesions represent a histologically heterogeneous group of tumors. Among these tumors, pineal parenchymal tumors and germ cell tumors (GCT) represent the most frequent types of lesions. According to the new WHO 2021 classification, pineal parenchymal tumors include five distinct histotypes: pineocytoma (PC), pineal parenchymal tumors of intermediate differentiation (PPTID), papillary tumor of the pineal region (PTPR), pinealoblastoma (PB), and desmoplastic myxoid tumor of the pineal region, SMARCB1-mutant; GCTs include germinoma, embryonal carcinoma, yolk sac tumor, choriocarcinoma, teratoma, mixed GCTs. Neuroradiological assessment has a pivotal role in the diagnostic work-up, surgical planning, and follow-up of patients with pineal masses. Surgery can represent the mainstay of treatment, ranging from biopsy to gross total resection, yet pineal region tumors associated with obstructive hydrocephalus may be surgically managed via ventricular internal shunt or endoscopic third ventriculostomy. Radiotherapy remains an essential component of the multidisciplinary treatment approach for most pineal region tumors; however, treatment volumes depend on the histological subtypes, grading, extent of disease, and the combination with chemotherapy. For localized germinoma, the current standard of care is chemotherapy followed by reduced-dose whole ventricular irradiation plus a boost to the primary tumor. For pinealoblastoma patients, postoperative radiation has been associated with higher overall survival. For the other pineal tumors, the role of radiotherapy remains poorly studied and it is usually reserved for aggressive (grade 3) or recurrent tumors. The use of systemic treatments mainly depends on histology and prognostic factors such as residual disease and metastases. For pinealoblastoma patients, chemotherapy protocols are based on various alkylating or platinum-based agents, vincristine, etoposide, cyclophosphamide and are used in association with radiotherapy. About GCTs, their chemosensitivity is well known and is based on cisplatin or carboplatin and may include etoposide, cyclophosphamide, or ifosfamide prior to irradiation. Similar regimens containing platinum derivatives are also used for non-germinomatous GCTs with very encouraging results. However, due to a greater understanding of the biology of the disease’s various molecular subtypes, new agents based on targeted therapy are expected in the future. On behalf of the EURACAN domain 10 group, we reviewed the most important and recent developments in histopathological characteristics, neuro-radiological assessments, and treatments for pineal region tumors.
