Abstract
BACKGROUND AND OBJECTIVES Stereotactic radiosurgery (SRS) has been an attractive treatment modality for both cranial and spinal hemangioblastomas, especially for multiple lesions commonly associated with von Hippel-Lindau (VHL) disease. This study aims to provide the largest long-term analysis of treatment efficacy and adverse effects of SRS for cranial and spinal hemangioblastomas at a single institution. METHODS We evaluated the clinical and radiological outcomes of patients with hemangioblastomas treated with CyberKnife SRS at our institute from 1998 to 2022. The follow-up data were available for 135 hemangioblastomas in 35 patients. Twenty-eight patients had 123 hemangioblastomas associated with VHL, and 7 had 12 sporadic hemangioblastomas. The median age was 36 years, and the median tumor volume accounted for 0.4 cc. The SRS was administered with the median single-fraction equivalent dose of 18 Gy to the 77% median isodose line. RESULTS At a median follow-up of 57 months (range: 3-260), only 20 (16.2%) of the VHL-associated and 1 (8.3%) sporadic hemangioblastomas progressed. The 5-year local tumor control rate was 91.3% for all hemangioblastomas, 91.7% among the sporadic lesions, and 92.9% in patients with VHL. SRS improved tumor-associated symptoms of 98 (74.8%) of 131 symptomatic hemangioblastomas, including headache, neck pain, dizziness, visual disturbances, dysesthesia, ataxia, motor impairment, seizures, and dysphagia. Two patients developed radiation necrosis (5.7%), and 1 of them required surgical resection. CONCLUSION SRS is a safe and effective treatment option for patients with hemangioblastomas in critical locations, such as the brainstem, cervicomedullary junction, and spinal cord, and in patients with multiple hemangioblastomas associated with VHL disease.

Abstract
Von Hippel-Lindau (VHL) disease is a dominantly inherited disorder marked by multiorgan tumors, such as central nervous system benign hemangioblastomas (CHB). Stereotactic radiosurgery (SRS) has also been used to treat CHB for a long time. The purpose of this meta-analysis is to provide a long-term outcome of SRS for VHL-associated CHB by reviewing published studies. We completed a Pubmed/Embase/SCOPUS/Cochrane Library literature search to get eligible studies published from January 1990 to December 2019 about using SRS to treat VHL-associated CHB. 15 studies met eligibility for qualitative systematic review, of which nine studies were ultimately eligible for quantity meta-analysis of 5-year tumor control rates (TCR), representing 170 subjects with a total of 660 lesions. Gamma Knife was the most published SRS method for VHL-associated CHB. The pooled 5-year TCR across the nine studies was 0.919 (95 %CI: 0.881-0.957). The pooled 5-year TCR for only intracranial lesions across eight studies was 0.917 (95 %CI: 0.876-0.957). Individual patient data were extracted from 9 studies, representing 298 lesions of 70 subjects. Sex, tumor volume, radiosurgery methods, marginal doses, maximum doses, the number of tumors for radiosurgery, age at the time of radiosurgery, tumor locations were not proven to be associated with tumor progression. SRS offered a satisfactory 5-year tumor control of CHB for VHL patients. Despite the paucity of randomized control trials, SRS is recommended to patients with limited surgical alternatives. However, the long-term outcomes and underlying factors associated with tumor progression remain to be investigated.

Abstract
Spinal and cerebellar hemangioblastomas are common in von Hippel-Lindau disease (vHLD) and usually treated surgically. Multifocal presence and surgically not amenable locations are issues that require a combined microsurgical and radiosurgical approach to control complex cases. We would like to present the case of a 37-year-old male patient who was diagnosed vHLD with multiple spinal and one infratentorial hemangioblastomas and holocord syrinx formation of the whole spinal cord. Combined microsurgical approaches to two spinal lesions and the cerebellar lesion followed by external beam radiotherapy of the posterior fossa and the whole spinal axis stabilized tumor growth of the asymptomatic lesions, while no recurrent tumors were detected at the site of surgery. A clinical deterioration connected to early postoperative deficits stabilized to a moderate gait ataxia. The follow-up after radiotherapy covered 60 months. A combination of microsurgery and radiosurgery for the surgically not amenable lesions is an adequate treatment regimen to stabilize tumor growth and clinical symptoms of multifocal spinal hemangioblastomas in vHLD, though the therapy should be limited to symptomatic or growing lesions.

Gamma Knife Stereotactic Radiosurgery favorably changes the clinical course of hemangioblastoma growth in von Hippel-Lindau and sporadic patients. J Neurooncol 2019; 142:471-478. [PMID: 30729402 DOI: 10.1007/s11060-019-03118-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Accepted: 02/01/2019] [Indexed: 02/08/2023]
Abstract
PURPOSE This is the first single-institution study of its size to characterize the treatment impact and to address the question of whether hemangioblastoma treatment with Gamma Knife Stereotactic Radiosurgery (GKRS) in both sporadic and VHL patients changes the characteristic saltatory hemangioblastoma growth pattern. METHODS The authors reviewed a single-institution tumor registry to identify patients who had received GKRS for hemangioblastomas between January 1st, 1999, and December 31st, 2017. RESULTS 15 patients with 101 lesions met search criteria with a median age of first GKRS of 39.2 years (interquartile range [IQR] of 25.7-57.4 years), including 96 VHL and 5 sporadic lesions. The median time from GKRS to last follow-up was 5.4 years (IQR 2.3-11.5 years). 4 lesions (4%) and 3 patients (20%) experienced a local failure. The 1-year, 3-year, and 5-year freedom from new hemangioblastoma formation rates were 97%, 80%, and 46% respectively. Multivariate analysis revealed a reduction in tumor volume after GKRS. Several variables associated with a greater percent reduction in volume from GKRS to last follow-up: non-cystic status (p = .01), no prior craniotomy (p = .04), and follow-up time from GKRS (p < .0001). CONCLUSIONS GKRS is a successful long-term treatment option for hemangioblastomas changing the clinical course from saltatory growth to reduction in tumor volume. Non-cystic tumors and those without prior craniotomy were associated with a greater percent reduction in volume from GKRS at last follow-up.

Abstract
Hemangioblastomas are rare, benign, vascular tumors of the central nervous system (CNS), often associated with von-hippel lindau (VHL) disease. Current therapeutic options include microsurgical resection or stereotactic radiosurgery (SRS). With no randomized controlled studies and minimal data beyond single-institution reviews, the optimal management approach for patients with CNS hemangioblastomas is unclear. We completed a Pubmed/SCOPUS literature search from January 1990 to January 2017 for eligible studies on SRS for CNS hemangioblastomas. Relevant articles were identified and reviewed in accordance to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. 26 studies met eligibility criteria for qualitative synthesis, representing 596 subjects and 1535 tumors. The Gamma Knife was the most published SRS method for CNS hemangioblastomas. After critical study appraisal for intra-study bias, 14 studies were used for quantitative meta-analysis of 5-year progression free survival (PFS). The pooled 5-year PFS across all eligible studies was 88.4%. No difference was observed between spine versus intracranial studies. Individual patient data (IPD) was extracted from 14 studies, representing 322 tumors. Univariate analysis of IPD revealed that VHL patients were younger, and had smaller tumors compared to those with sporadic disease. Adverse events were associated with increasing marginal dose, independent of tumor volume. VHL status, sex, radiosurgical method, tumor location, and tumor volume were not found to be significantly associated with tumor progression. Multiple studies show excellent tumor control at 5-year follow up, however, the long-term efficacy of SRS for CNS hemangioblastomas still needs to be investigated, and the studies exploring the role of SRS for early treatment of asymptomatic lesions is wanting.

Abstract
Recent publications have reported stereotactic radiosurgery as an effective and safe treatment for intracranial hemangioblastomas. However, because of the low incidence of these particular tumors, reports on large patient number studies have not yet been available. The objective of this study was to analyze the clinical results of 14 patients with 56 intracranial hemangioblastomas treated with linear accelerator (linac)-based stereotactic radiosurgery (SRS) and radiotherapy (SRT) in the same institute. The median age of patients was 41 years (range, 28-73 years). Nine of the patients (64%) had von Hippel-Lindau disease. A total of 39 lesions (70%) were treated with CyberKnife (CK), and 17 lesions (30%) were treated with X-Knife. The median pretreatment volume was 0.26 cm(3) (range, 0.026-20.4 cm(3)). The median marginal dose was 20 Gy (range, 10-32 Gy) in 1 fraction (range, 1-10 fractions). The median follow-up time was 24 months (range, 11-89 months). At the last follow-up, 47 tumors (84%) were stable, 7 (13%) decreased and 2 (4%) increased. The 1-, 2- and 6-year local control rates were 98%, 88% and 73%, respectively. No radiation complications were observed in this study. There was a trend toward local failure only in cystic tumors, but this trend was not found to be statistically significant. SRS/SRT achieved a high local control rate in intracranial hemangioblastomas without radiation-induced complications.

Abstract
Supratentorial hemangioblastoma is a rare form of hemangioblastoma; little information is available regarding prognosis, treatment, and clinical characteristics, because the available literature is primarily composed of case reports and small case series. Therefore, we performed a systematic review of the literature to analyze clinical characteristics, disease progression, and surgical outcomes with respect to survival for supratentorial hemangioblastomas. The rate of progression-free survival (PFS) was determined using Kaplan-Meier analysis. Differences in categorical factors, including location of tumor and diagnosis of von Hippel-Lindau (VHL) disease, were analyzed using the Pearson χ(2) test. A total of 106 articles met the search criteria, which combined for a total of 132 patients. Of the patients with supratentorial tumors, 60% had VHL disease, and 31 (84%) of 37 patients with tumors in the sellar/suprasellar region had associated VHL (χ(2), P < .001). Five-year PFS for gross-total resection and subtotal resection were 100% and 53%, respectively (Log rank, P < .01). On the basis of our analysis of the literature on published cases of supratentorial hemangioblastoma, gross-total resection appears to be superior to other treatment modalities in extending PFS. Von Hippel-Lindau disease is positively correlated with supratentorial hemangioblastoma when compared with non-supratentorial CNS hemangioblastomas, particularly when present in the sellar/suprasellar region.

Abstract
To determine the effectiveness of stereotactic radiosurgery (SRS) treatment to central nervous system (CNS) hemangioblastomas in von Hippel-Lindau disease (VHL), we analyzed long-term results in VHL patients treated with SRS. Patients were enrolled in a prospective VHL natural history study, undergoing SRS treatment of CNS hemangioblastomas. Treatment regimens, serial clinical evaluations, and longitudinal imaging data were analyzed. Twenty VHL patients (10 males and 10 females) underwent SRS treatment of 44 CNS hemangioblastomas (39 cerebellar and 5 brainstem). Mean (+/-SD) age at treatment was 37.5 +/- 12.0 years (range: 13-67). Mean follow-up was 8.5 +/- 3.2 years (range: 3.0-17.6 years). All patients were alive at last follow-up. Mean treated tumor volume was 0.5 +/- 0.7 cm(3) (range: 0.01-3.6 cm(3)). Mean prescription dose was 18.9 Gy (range: 12-24 Gy) at the tumor margin. Local control rate at 2, 5, 10, and 15 years after SRS treatment was 91%, 83%, 61%, and 51%, respectively. Univariate analysis did not identify variables associated (P > .05) with worse tumor control at last follow-up. Thirty-three percent of SRS-treated small (<1.0 cm diameter), asymptomatic tumors progressed over a long-term follow-up. There were no long-term adverse radiation effects. Although SRS treatment of hemangioblastomas in VHL has a low risk for adverse radiation effects, it is associated with diminishing control over a long-term follow-up. These results indicate that SRS should not be used to prophylactically treat asymptomatic tumors and should be reserved for the treatment of tumors that are not surgically resectable.

Abstract
OBJECTIVE Stereotactic radiosurgery has been used for nearly 2 decades to treat hemangioblastomas, particularly those that are in surgically inaccessible locations or that are multiple, as is common in von Hippel-Lindau disease. There is a paucity of long-term published radiosurgical treatment outcomes, particularly for spinal lesions, in a large patient population. The purpose of this study was to provide a long-term retrospective evaluation of radiosurgical hemangioblastoma treatment effectiveness, with a special emphasis on the relatively recent use of frameless, image-guided radiosurgery in the treatment of spinal lesions. METHODS From 1991 to 2007, 92 hemangioblastomas in 31 patients, 26 with von Hippel-Lindau disease, were treated with radiosurgery (27 tumors treated with frame-based linear accelerator radiosurgery, and 67 tumors were treated with CyberKnife radiosurgery). The mean patient age was 41 years (range, 18-81 years). The radiation dose to the tumor periphery averaged 23.4 Gy (range, 12-40 Gy). The mean tumor volume was 1.8 cm (range, 0.058-65.4 cm). Tumor response was evaluated in serial, contrast-enhanced, computed tomographic, and magnetic resonance imaging scans. RESULTS Clinical and radiographic follow-up data were available for 82 hemangioblastoma tumors. Only 13 (16%) of the treated hemangioblastomas progressed, whereas 18 tumors (22%) showed radiographic regression, and 51 tumors (62%) remained unchanged in size. With median follow-up of 69 months (range, 5-164 months), the actuarial local control rates at 36 and 60 months were 85% and 82%, respectively. Radiosurgery improved lesion-associated symptoms in 36 of 41 tumors. During the follow-up period, 9 patients died of causes unrelated to the progression of their treated hemangioblastomas, and 5 patients developed radiation necrosis. CONCLUSION Stereotactic radiosurgery is safe and effective in the treatment of hemangioblastomas and is an attractive alternative to surgery for patients, including those with von Hippel-Lindau disease.

Abstract
BACKGROUND The results of gamma knife radiosurgery for haemangioblastomas were retrospectively studied to assess the efficacy for tumour growth control and clarify the clinical indications for gamma knife radiosurgery in these tumours. METHODS The medical records of 22 patients with 67 tumours, 12 men and 10 women aged 20-73 years (mean 51.9 years), who underwent gamma knife radiosurgery for haemangioblastomas between January 1993 and January 2006, were retrospectively reviewed. Ten patients with 54 lesions had von Hippel-Lindau disease. The mean tumour volume was 1.69 cm(3) (range 0.0097-16.4 cm(3)). Nineteen patients had undergone 1-4 open surgery procedures (mean 1.5) before gamma knife radiosurgery. Tumours without a cystic component, (the solid type), were found in 54 lesions and tumours associated with cyst, (the mural nodule with cyst type), in 13 lesions. The marginal dose was 8-30 Gy (mean 14.0 Gy). FINDINGS Follow-up magnetic resonance (MR) imaging was performed at 9-146 months (mean 63 months). The control rate for tumour growth was 83.6%. The only factor affecting tumour growth control was the presence of a cystic component at the time of gamma knife radiosurgery in both univariate and multivariate analysis. No complication such as radiation-induced peritumoural oedema or radiation necrosis occurred. CONCLUSION The presence of cystic components at the time of gamma knife radiosurgery was the only factor significantly correlated with unfavourable tumour growth control by gamma knife radiosurgery for haemangioblastomas. Gamma knife radiosurgery is effective for solid type tumours, even if the marginal dose is relatively low. Surgical removal is recommended for mural nodule with cyst type tumours, when possible.

Abstract
PURPOSE To assess the clinical outcomes and toxicity in patients receiving fractionated external beam radiotherapy (EBRT) for hemangioblastoma of the central nervous system, treated at two Canadian radiation oncology institutions. METHODS AND MATERIALS Between January 1980 and December 2004, the data of all patients receiving EBRT for central nervous system hemangioblastoma were retrospectively reviewed. The patient, tumor, and treatment characteristics were collected and overall survival, disease-free survival, and EBRT-related toxicities assessed. RESULTS A total of 18 cases, 5 associated with von Hippel-Lindau disease (VHL) and 13 sporadic (non-VHL), with a total 31 lesions, were documented. These were located in the cerebellum in 20 and spinal cord in 8 patients. EBRT was delivered for recurrence in 12, adjuvantly for residual disease in 4, and definitively in 2. The EBRT schedules ranged from 50.0 to 55.8 Gy in 1.8-2.0-Gy daily fractions (n = 17), typically with parallel-opposed fields to the cerebellar target volumes and direct posterior fields for spinal disease. At a median follow-up of 5.1 years (range, 0.1-14.5), the 5-year OS rate was 69% (95% confidence interval [CI], 50-96%), decreasing to 30% (95% CI, 10-87%) at 10 years. The disease-free survival rate at 5 and 10 years was 57% (95% CI, 37-87%) and 30% (95% CI, 11-83%), respectively. The outcomes differed according to VHL status. The 5-year OS rate was 100% for those with VHL compared with 55% (95% CI, 32-95%) for those with non-VHL disease (log-rank p = 0.003), and the 5-year disease-free survival rate was 80% (95% CI, 52-100%) with VHL compared with 48% (95% CI, 26-89%) without (log-rank p = 0.036). CONCLUSIONS Fractionated EBRT has a role in the management of extensive intracranial and/or spinal cord disease, the adjuvant treatment of residual postoperative disease, and the treatment of recurrence. More favorable outcomes were reported for VHL-associated lesions than for sporadic cases.

Abstract
OBJECTIVE To assess the risk of radiosurgery inducing malignancy in neurofibromatosis-2 (NF2) and von Hippel-Lindau disease. METHODS A retrospective cohort study of 118 NF2 and 19 von Hippel-Lindau disease patients, totalling 906 and 62 patient-years of follow-up data, respectively. RESULTS Two cases of intracranial malignancy were identified, both of which occurred in NF2 patients. One of these was thought to have arisen before the radiosurgery; the other was a glioblastoma diagnosed 3 years after radiosurgery. CONCLUSION Because gliomas may occur in as many as 4% of NF2 patients, this may not represent an increased risk. We continue to offer radiosurgery treatment to selected NF2 and von Hippel-Lindau disease patients and consider that the late risk of malignancy arising after irradiation must be put in the context of the condition being treated, the treatment options available to these individuals, and their life expectancy.

Abstract
Supratentorial hemangioblastomas (HBL) have been rarely described in the literature. Herein we report the fourth case of pituitary stalk HBL diagnosed concurrently with cerebellar HBLs in a 51-year-old woman with von Hippel-Lindau disease. Complete resection of the lesion was achieved using left frontopterional craniotomy and no recurrence was observed after 8 years of follow-up. The clinical presentation, radiological features, pathological findings, and the management of this particular case are discussed in the light of the available literature. To our knowledge, this case is the only pituitary stalk HBL with total resection, and a long follow-up fully documented.

Abstract
Thermal photocoagulation of small peripheral angiomas is the treatment of choice for capillary hemangiomas in patients with von Hippel-Lindau disease. Larger peripheral angiomas are better treated with beta-ray brachytherapy resulting in improved results in terms of local tumor control and the side effects of treatment. Photodynamic treatment is an alternative option in the management of capillary hemangiomas of the retina. Further improvement of the treatment results of photodynamic therapy may be achieved by combination with intravitreal drugs. External beam radiation using either stereotactic techniques or proton radiation must be considered as experimental. The treatment of juxtapapillary angiomas is still a therapeutic dilemma. Vitreoretinal surgery should be confined to advanced stages with tractional detachment or when no other treatment option is available to salvage the eye.

Abstract
A 71-year-old Caucasian female presented to our service with disseminated cranial and spinal haemangioblastomata but no other features to suggest the von Hippel-Lindau syndrome. We feel that this represents cellular dissemination through the cerebro-spinal fluid and may be an intermediate step to the development of frank haemangioblastomatosis. By comparing this presentation to that of other tumours we have suggested a potential pathological mechanism and have discussed its management.

Abstract
In recent years the use of radiation treatment for benign tumours has increased with the advent of stereotactic delivery and, in particular, single high dose gamma knife therapy. This has been particularly true for benign CNS (central nervous system) tumours such as vestibular schwannoma, meningioma, pituitary adenoma, and haemangioblastoma. While short term follow up in patients with isolated tumours suggests this treatment is safe, there are particular concerns regarding its use in childhood and in tumour predisposing syndromes. We have reviewed the use of radiation treatment in these contexts with particular regard to malignant transformation and new tumour induction. This review indicates that much more caution is warranted regarding the use of radiation treatment for benign tumours in childhood and in tumour prone conditions such as the neurofibromatoses.
