Approach to the patient: Concept and application of targeted radiotherapy in the paraganglioma patient
J Clin Endocrinol Metab. 2024 Apr 23:dgae252. doi: 10.1210/clinem/dgae252. Online ahead of print.ABSTRACTParagangliomas can metastasize, posing potential challenges in both symptomatic management and disease control. Systemic targeted radiotherapies using 131I-MIBG and 177Lu-DOTATATE are a mainstay in the treatment of metastatic paragangliomas. This clinical scenario and discussion aim to enhance physicians' knowledge of the stepwise approach to treat these patients with paraganglioma targeted radiotherapies.

Microsurgery in carotid body paraganglioma
CONCLUSIONS: The small study size and its retrospective nature suggests caution; however, our results show that microsurgery can allow a safe and precise dissection of the carotids and nerves.PMID:38651551 | DOI:10.14639/0392-100X-N2761 (Source: Acta Otorhinolaryngologica Italica)

Cauda equina neuroendocrine tumor: a report of three cases and review of the literature with focus on differential diagnosis and postoperative management
We report on three patients, two of them presenting with a clinical history of lower back pain and sciatica. In all cases magnetic resonance imaging (MRI) of the lumbosacral spine with and without Gd-DTPA revealed an intradural lesion with strong contrast enhancement, first described as atypical ependymoma or schwannoma. A complete tumor resection was achieved in all cases, the histopathological diagnosis classified the tumors as CENETs.In our literature review, a total of 688 articles were screened and 162 patients were included. Patients demographic data, clinical symptoms, resection and recurrence were recorded.Discussi...

Diagnostic performance of [68Ga]DOTATATE PET/CT, [18F]FDG PET/CT, MRI of the spine, and whole-body diagnostic CT and MRI in the detection of spinal bone metastases associated with pheochromocytoma and paraganglioma
Conclusions[68Ga]DOTATATE PET/CT should be the modality of choice in PPGL-related spinal bone metastases due to its superior detection rate.Clinical relevance statementIn a prospective study of 43 pheochromocytoma/paraganglioma participants with spinal bone metastases, [68Ga]DOTATATE PET/CT had a superior per-lesion detection rate of 98.7% (377/382), compared to [18F]FDG PET/CT (p < 0.001), MRI of the spine (p < 0.001), whole-body CT (p < 0.001), and whole-body MRI (p < 0.001).Graphical abstractKey Points• Data regarding head-to-head comparison between functional and anatomic imaging modal...

Head and neck paragangliomas (HNPGLs) are rare and have high rates of genetic mutations. We conducted a retrospective review of 187 patients with 296 PGLs diagnosed between 1974 and 2023. The mean age of diagnosis was 48.8 years (range 10 to 82) with 69.0% female and 26.5% patients with multiple PGLs. Among 119 patients undergoing genetic testing, 70 (58.8%) patients had mutations, with SDHB (30) and SDHD (26) being the most common. The rates of metastasis and recurrence were higher among patients with SHDB mutations or SDHD mutations associated with multiple PGLs. Metabolic evaluation showed elev...

Paraaortic Extra-Adrenal Paraganglioma: Challenging Robotic Resection
CONCLUSIONS: Robotic-assisted resection can be safe and effective for retroperitoneal malignant paragangliomas. However, management extends beyond surgery and requires cascade genetic testing to address familial risks. Because of the high probability of cancer associated with SDHB mutation, lifelong patient surveillance is imperative.PMID:38615151 | DOI:10.1245/s10434-024-15267-z (Source: Ann Oncol)

Opposing effects of cannabidiol in patient-derived neuroendocrine tumor, pheochromocytoma/paraganglioma primary cultures
CONCLUSIONS: We suggest a potential novel treatment option for some NETs/PPGLs, but also provide evidence for caution when applying cannabinoids as supportive therapy for pain or appetite management to cancer patients, and possibly as health supplements.PMID:38605427 | DOI:10.1210/clinem/dgae241 (Source: The Journal of Clinical Endocrinology and Metabolism)

Outcomes of SDHB pathogenic variant carriers: A systematic review and meta-analysis
CONCLUSION: Penetrance for PPGL in SDHB PV carriers increases linearly with age. Affected carriers are at risk of developing and dying from metastatic disease, or of developing second tumors. Lifelong surveillance is appropriate.PMID:38605204 | DOI:10.1210/clinem/dgae233 (Source: The Journal of Clinical Endocrinology and Metabolism)

Cancers, Vol. 16, Pages 1466: Long-Term Surgical Outcome of Class A and B Tympanomastoid Paragangliomas
Conclusions: Tympanomastoid PGL represents the most common neoplasm of the middle ear space. The most frequent presenting symptoms include pulsatile tinnitus and hearing loss, whereas the presence of retrotympanic mass was evident in all cases at the time of initial otoscopic evaluation. Proper documentation of facial function and audiometric evaluation are crucial elements of preoperative workup. The most preferred preoperative radiologic examination is high-resolution computer tomography (HRCT), whereas magnetic resonance imaging (MRI) with or without gadolinium enhancement is reserved for cases with a dilemma of carotid...
