Pheochromocytomas can be a part of familial neoplastic syndromes, in which case they tend to be multiple and involve both adrenal glands. Therefore, sparing adrenocortical function represents a major concern while dealing with these hereditary lesions. Herein, we describe the clinical characteristics and the management strategy of a patient with von Hippel-Lindau (VHL) disease who had multiple, bilateral pheochromocytomas as well as bilateral renal masses, pancreatic masses, and a paracaval mass. Only a portion of the left adrenal gland has remained in situ after two consecutive open surgeries and a percutaneous radiofrequency ablation which have been performed to treat the various components of this syndrome. No adrenal or extra-adrenal pheochromocytoma recurrences have been detected during a follow-up period of more than 2 years. Pancreatic and adrenal functions were normal throughout the postoperative period and never necessitated any replacement therapy. Adrenal cortex-sparing surgery is a valid option for VHL disease patients who present with synchronous bilateral adrenal pheochromocytomas.

Vhl Disease

von Hippel–Lindau (VHL) disease is an autosomal dominant disorder caused by heterozygous mutations in the VHL tumor suppressor gene that is characterized by the occurrence of multiple endocrine and nonendocrine lesions. This review focuses on the endocrine manifestations of VHL disease. Pancreatic neuroendocrine proliferations (ductuloinsular complexes, islet dysplasia, endocrine microadenoma, and neuroendocrine tumors), pheochromocytomas, and extra-adrenal paragangliomas are important endocrine manifestations of VHL disease. They frequently display characteristic clinical, biochemical, and histopathologic features that, although not pathognomonic, can be helpful in suggesting VHL disease as the underlying etiology and distinguishing these tumors from sporadic cases. Recent improvements in treatment and outcomes of renal cell carcinomas have allowed pancreatic neuroendocrine tumors to emerge as a significant source of metastatic disease, making the accurate recognition and classification of these neoplasms by the pathologist of utmost importance to determine prognosis, treatment, and follow-up strategies for affected patients.

Long Term Prognosis

Worldwide, the syndromes of paraganglioma (PGL), somatostatinoma (SOM) and early childhood polycythemia are described in only a few patients with somatic mutations in the hypoxia-inducible factor 2 alpha (HIF2A). This study provides detailed information about the clinical aspects and course of 7 patients with this syndrome and brings into perspective these experiences with the pertinent literature. Six females and one male presented at a median age of 28 years (range 11–46). Two were found to have HIF2A somatic mosaicism. No relatives were affected. All patients were diagnosed with polycythemia before age 8 and before PGL/SOM developed. PGLs were found at a median age of 17 years (range 8–38) and SOMs at 29 years (range 22–38). PGLs were multiple, recurrent and metastatic in 100, 100 and 29% of all cases, and SOMs in 40, 40 and 60%, respectively. All PGLs were primarily norepinephrine-producing. All patients had abnormal ophthalmologic findings and those with SOMs had gallbladder disease. Computed tomography (CT) and magnetic resonance imaging revealed cystic lesions at multiple sites and hemangiomas in 4 patients (57%), previously thought to be pathognomonic for von Hippel–Lindau disease. The most accurate radiopharmaceutical to detect PGL appeared to be [18F]-fluorodihydroxyphenylalanine ([18F]-FDOPA). Therefore, [18F]-FDOPA PET/CT, not [68Ga]-(DOTA)-[Tyr3]-octreotate ([68Ga]-DOTATATE) PET/CT is recommended for tumor localization and aftercare in this syndrome. The long-term prognosis of the syndrome is unknown. However, to date no deaths occurred after 6 years follow-up. Physicians should be aware of this unique syndrome and its diagnostic and therapeutic challenges.

Abstract Purpose. von Hippel Lindau (VHL) disease is a familiar syndrome associated with benign and malignant tumors. These tumors appear in the retina, cerebellum, spinal cord, and kidney. Retinal hemangioblastomas are one of the earliest and most frequent manifestations of this entity, and they can lead to blindness at a young age. Propranolol could be a promising treatment for retinal hemangioblastomas in von Hippel Lindau disease. Methods. Prospective cohort study. Seven patients with VHL disease and ocular affection that had rejected conventional treatment were included. Prospective analysis of seven patients was performed. We evaluated them for three years, with a complete ophthalmic evaluation that included: visual acuity, intraocular pressure, an examination of the anterior segment of the eye, fundoscopy, retinography, and optical coherence tomography (OCT). Heart rate and blood pressure on each patient were also measured. During the follow-up evaluation, two patients discontinued the treatment with propranolol after the first year and rejected any further treatment for their ocular affection; the rest continued therapy for the three years. Results: Visual acuity and tumor areas remained stable in 4 patients. Increased and new retinal exudation area was found in the two patients that discontinued the treatment with oral propranolol. Conclusions: Oral propranolol has shown a role in the reabsorption of retinal exudates in patients with von Hippel Lindau affection. It could delay or stabilize the ocular disease, maintaining visual acuity, and avoiding further complications in these patients. It is a well-known and available drug, without so many secondary effects, that could also have a role in other ocular diseases that course with exudation.

Survival Plot

Despite the rise of small renal tumour (SRMs) diagnosis and related surgeries, death rate of kidney cancer is increasing, suggesting a non-optimal management of SRMs. Active Surveillance (AS) for kidney cancer was introduced to deal with this paradox. However, incertitude remains on whether and when AS can replace surgery in selected patients. We performed a literature search, reviewed and discussed the evidence in favour of AS or surgery for SRMs. Histopathology and natural history of SRMs, including the percentage of benign tumours amongst SRMs, tumour growth rate, life expectancy of SRMs patients being generally older, and current results of AS series seem to support its use in selected groups. However, kidney cancer is a heterogeneous entity, metastasis and ≥T3a status can be found also for SRMs and no biomarkers or other parameters are available to identify lethal SRMs. Despite the recent improvement in the diagnostic and prognostic work through imaging modalities, renal biopsies and nomograms, the interpretation of a survival plot subjectively is still not possible. The majority of AS studies are retrospective and extensive level 1 evidence cohorts with long term follow up are lacking. No unanimity is present regarding inclusion and exclusion criteria to undergo AS, follow up timings and AS exit criteria. Surgery is the only definitive treatment and remains the current standard. A better understanding of kidney cancer biology and SRMs behaviour is needed to clarify the role of AS and its indications.

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 cm3 (range, 0.058–65.4 cm3). 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.

Von Hippel Lindau Disease

Abstract OBJECTIVE Hemangioblastomas of the central nervous system are rare vascular tumors that can occur as sporadic lesions or as component tumors of autosomal dominant von Hippel-Lindau disease. With the availability of magnetic resonance imaging, asymptomatic tumors are detected more frequently, especially among patients with von Hippel-Lindau disease, and the questions of whether and when these lesions should be treated arise. To identify surgical outcomes and the timing of surgery for intramedullary hemangioblastomas, we retrospectively analyzed data for a series of 28 consecutive patients whom we surgically treated for intramedullary hemangioblastomas in the past 10 years. METHODS All tumors were completely removed. Functional grades, according to the McCormick scale, were determined before and after surgery and in follow-up assessments. Several clinical characteristics were correlated with changes in functional grades in follow-up assessments, compared with preoperative grades. RESULTS Functional grades in follow-up assessments improved for 28.6% of the patients and remained unchanged for 71.4%. No patient was in worse condition, compared with preoperative status. Peritumoral edema on preoperative magnetic resonance imaging scans was correlated with significantly higher surgical morbidity rates. Four asymptomatic patients were surgically treated because of tumor or pseudocyst progression on serial magnetic resonance imaging scans. All of those patients remained asymptomatic postoperatively. CONCLUSION Intramedullary hemangioblastomas can be removed with low surgical morbidity rates and excellent long-term prognoses. The timing of surgery for patients with von Hippel-Lindau disease and multiple lesions remains a matter of debate. On the basis of our data, we established the strategy of operating also on asymptomatic lesions that exhibit radiological progression, before significant neurological deficits occur, which are often not reversible.
