AI Article Synopsis

  • The study aims to describe the clinical features, imaging, management, and outcomes of brown tumors (BT) of the jaws, while also reviewing existing literature to clarify debates surrounding these lesions.
  • Sixteen patients with BT linked to different forms of hyperparathyroidism were treated, revealing that the majority had primary or secondary hyperparathyroidism and that surgical intervention led to tumor regression in some cases.
  • The findings indicate that parathyroidectomy is the most effective treatment for primary hyperparathyroidism, while effective management of chronic renal insufficiency is crucial for success in treating secondary and tertiary hyperparathyroidism.

Article Abstract

Objectives: (1) Describe the clinical spectrum, imaging features, management, and outcome of brown tumors (BT) of the jaws. (2) Determine via a literature review the facts and controversies around the characteristics and management of this lesion.

Materials And Methods: Our study was approved by the institutional committee of Sahloul University Hospital in accordance with the ethical standards of the Declaration of Helsinki. Sixteen patients with BT in the context of a primary, secondary, and tertiary hyperparathyroidism were treated and followed up during their recovery.

Results: This study reports 16 patients with a mean age of 48 years old. Brown tumor lesions were associated with primary hyperparathyroidism in 6 cases (38%), secondary hyperparathyroidism to chronic kidney failure in 5 cases (31%), and tertiary hyperparathyroidism in the context of a long lasting CRI in 5 cases. Their location was maxillary in 7 cases, mandibular in 5 cases, and bimaxillary in 4 cases. The treatment consisted of parathyroidectomy in 13 patients, maxillary resection in 3 cases, and vitamin D treatment in 2 cases. Favorable outcomes, characterized by tumor regression, were reported in 9 cases, whereas unfavorable evolution was observed among 7 patients.

Conclusion: Parathyroidectomy is the gold standard treatment for primary hyperparathyroidism. It resulted in a total regression in all our cases. Regarding secondary hyperparathyroidism, blood screening and chronic renal insufficiency follow-up are critically valuable to detect this condition at an early stage, hence increasing the success rate of brown tumor regression. Our secondary and tertiary hyperparathyroidism results were miscellaneous; although it is important to emphasize the importance of the chronic renal insufficiency management to ensure a success.

Clinical Relevance: Brown tumors should be included in the differential diagnosis of giant cell lesions. Parathyroidectomy is usually sufficient to induce the total regression of the lesion in primary hyperparathyroidism cases. A more delicate approach is needed regarding secondary hyperparathyroidism. Meticulous control of chronic renal insufficiency is mandatory in addition to parathyroidectomy.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

SSTR2-Targeted Theranostics in Hepatocellular Carcinoma.

Cancers (Basel)

January 2025

The Brown Foundation Institute of Molecular Medicine, McGovern Medical School, The University of Texas Health Science Center, Houston, TX 77054, USA.

Background: While the clinical use of radiolabeled somatostatin analogs is well established in neuroendocrine tumors, there is growing interest in expanding their application to other somatostatin receptor 2 (SSTR2)-expressing cancers. This study investigates the potential utility of SSTR2-targeted theranostics in hepatocellular carcinoma (HCC).

Methods: SSTR2 expression in HCC cell lines and clinical samples was evaluated using qRT-PCR, Western blot analysis, and a public dataset.

Purpose: To investigate whether hormone receptor-positive, human epidermal growth factor receptor 2-low (HR+HER2-low) versus HR+HER2-zero early breast cancers have distinct genomic and clinical characteristics.

Methods: This study included HR+, HER2-negative early breast cancers from patients enrolled in the phase III, randomized BIG 1-98 and SOFT clinical trials that had undergone tumor genomic sequencing. Tumors were classified HR+HER2-low if they had a centrally reviewed HER2 immunohistochemistry (IHC) score of 1+ or 2+ with negative in situ hybridization and HR+HER2-zero if they had an HER2 IHC score of 0.

Triple-negative breast cancer (TNBC) is a highly metastatic subtype of breast cancer. The epithelial-to-mesenchymal transition is a nonbinary process in the metastatic cascade that generates tumor cells with both epithelial and mesenchymal traits known as hybrid EM cells. Recent studies have elucidated the enhanced metastatic potential of cancers featuring the hybrid EM phenotype, highlighting the need to uncover molecular drivers and targetable vulnerabilities of the hybrid EM state.
