Abstract
Spinal cord tumors, though rare, present formidable challenges in clinical management due to their intricate nature. Traditional treatment modalities like surgery, radiation therapy, and chemotherapy have been the mainstay for managing these tumors. However, despite significant advancements, challenges persist, including the limitations of surgical resection and the potential side effects associated with radiation therapy. In response to these limitations, a wave of innovative approaches is reshaping the treatment landscape for spinal cord tumors. Advancements in gene therapy, immunotherapy, and targeted therapy are offering groundbreaking possibilities. Gene therapy holds the potential to modify the genes responsible for tumor growth, while immunotherapy harnesses the body's own immune system to fight cancer cells. Targeted therapy aims to strike a specific vulnerability within the tumor cells, offering a more precise and potentially less toxic approach. Additionally, novel surgical adjuncts are being explored to improve visualization and minimize damage to surrounding healthy tissue during tumor removal. These developments pave the way for a future of personalized medicine for spinal cord tumors. By delving deeper into the molecular makeup of individual tumors, doctors can tailor treatment strategies to target specific mutations and vulnerabilities. This personalized approach offers the potential for more effective interventions with fewer side effects, ultimately leading to improved patient outcomes and a better quality of life. This evolving landscape of spinal cord tumor management signifies the crucial integration of established and innovative strategies to create a brighter future for patients battling this complex condition.

Abstract
Patients with new-onset malignant spinal lesions often have an urgent need for local spine intervention and systemic therapy. For optimal management, it is crucial to diagnose the underlying disease as quickly and reliably as possible. The aim of our current study was to determine the feasibility, sensitivity, specificity, and diagnostic certainty of complementary cytological evaluation of spinal lesions suspected of malignancy. In 44 patients, we performed histopathological biopsies and in parallel cytologic preparations from the malignant site. Cytological smears were prepared and stained for May-Grunwald and Giemsa. Bone biopsies were histopathologically analyzed according to the existing standard-of-care practices. In 42 of 44 cases (95%), a cytological sample was successfully obtained. In 40 cases (95.2%, Cohen’s kappa: 0.77), the cytological diagnosis agreed with the histological diagnosis regarding the identification of a malignant lesion. This resulted in a sensitivity of 97% and a specificity of 80% as well as a diagnostic safety of 95%. Cytological analysis in the context of spinal surgery proved sufficient to establish a diagnosis of malignancy or its exclusion, expanding the existing diagnostic spectrum. Furthermore, implementation of this process as a routine clinical diagnostic might shorten the time to diagnosis and improve the treatment of this vulnerable patient group.

Biopsy of the same organ within 30 days: a potential radiology performance measure. Abdom Radiol (NY) 2021; 46:4509-4515. [PMID: 33963912 DOI: 10.1007/s00261-021-03103-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 04/15/2021] [Accepted: 04/21/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE To assess the potential value of repeat image-guided biopsy within 30 days as a radiology performance metric. METHODS This was a HIPAA-compliant IRB-approved retrospective cohort study of all consecutive ultrasound- and CT-guided core biopsies of the chest, abdomen, and pelvis performed at one institution November 2016 to June 2020. The inclusion criterion was repeat biopsy of the same organ within 30 days of the initial biopsy. Details of both biopsies were recorded, including indication, organ, post-biopsy histology, performing service, performing provider. Histologic concordance between initial and repeat biopsies was calculated. Proportions and 95% confidence intervals were calculated. RESULTS Repeat biopsy was performed after 1.9% (95% CI 1.5-2.4% [N = 89]) of 4637 initial biopsies. For structures with ≥ 100 biopsies performed, the repeat biopsy proportion ranged from 1.3% (5/378, US-guided renal biopsy) to 2.7% (11/413, CT-guided retroperitoneal biopsy). The most common indication for initial biopsy was possible malignancy (66% [59/89]). The most common indication for repeat biopsy was radiology-histology discrepancy (36% [32/89]). Repeat biopsies were more likely to show malignant cells and to have diagnostic tissue (Repeat: 48.3% malignant; 20.2% benign; 1.1% nondiagnostic; Initial: 25.8% malignant; 23.6% benign; 14.6% nondiagnostic). The most common histology difference after repeat biopsy was a change in malignant diagnosis (38.2% [34/89]). CONCLUSION Repeat percutaneous biopsy within 30 days of the same organ is uncommon (~ 2%), but when indicated, it commonly changes diagnosis and improves diagnostic yield. Repeat biopsy within 30 days is a potential performance measure for radiology procedure services.
