Special Issue Information

Dear Colleagues,

This Special Issue will showcase cutting-edge research and clinical insights in the multidisciplinary field of bone and soft tissue tumor diagnosis and management, covering both benign and malignant tumors, such as osteosarcoma, chondrosarcoma, Ewing’s sarcoma, and liposarcoma. The main focus areas will include 1) novel diagnostic techniques, such as advanced imaging, molecular/genomic profiling, and AI-assisted pathological diagnosis; 2) unique case reports highlighting rare cases, diagnostic challenges, or innovative treatment approaches; and 3) translational research linking laboratory findings with clinical practice, prognostic markers, and personalized treatment strategies. We welcome original research, systematic reviews, clinical trials, and case studies, with an emphasis on multidisciplinary collaboration (orthopedic oncology, radiology, pathology, and medical oncology). This Special Issue will serve as a comprehensive resource for clinicians and researchers dedicated to improving the prognosis of patients with bone and soft tissue tumors. Additionally, we encourage submissions exploring the role of emerging technologies, such as liquid biopsy, circulating tumor cells, and single-cell sequencing, in the context of bone and soft tissue tumor diagnosis and management.

Background/Objectives: Mandibular bone invasion is a common and clinically relevant feature of OSCC, particularly in tumors of the lower alveolus, floor of mouth, and retromolar trigone. The prognostic value of the pattern of invasion—rather than its mere presence—remains insufficiently defined. Therefore, we evaluated [...] Read more.
Background/Objectives: Mandibular bone invasion is a common and clinically relevant feature of OSCC, particularly in tumors of the lower alveolus, floor of mouth, and retromolar trigone. The prognostic value of the pattern of invasion—rather than its mere presence—remains insufficiently defined. Therefore, we evaluated the prognostic relevance of erosive vs. infiltrative mandibular invasion and the diagnostic reliability of preoperative CT. Methods: This retrospective, single-center observational cohort study included 83 patients with OSCC involving or adjacent to the mandible who underwent surgical resection at the Department of Oral and Maxillofacial Surgery, University Hospital Olomouc (2008–2018). Bone invasion type was classified histopathologically as erosive or infiltrative. Survival outcomes were analyzed using Kaplan–Meier and Cox regression methods. Correlation between radiologic and histologic findings was assessed using Cohen’s kappa statistics. Results: Mandibular invasion was confirmed in 50.6% of cases, of which roughly two-thirds were infiltrative. DSS differed across invasion groups (log-rank p = 0.012): infiltrative had a median DSS of 14.5 months (95% CI 0.0–32.8), no invasion had 54.2 months (CI not estimable), while erosive did not reach the median (fewer than half experienced the event). In the adjusted model (covariates: invasion type, ENE, grade, margins), infiltrative vs. no invasion was associated with worse DSS (aHR 1.93, 95% CI 1.02–3.64; p = 0.042); for OS, erosive vs. no invasion showed a protective association (aHR 0.39, 95% CI 0.16–0.96; p = 0.041). Positive/close margins were independently adverse across endpoints (e.g., DSS aHR 3.30, 95% CI 1.74–6.22). CT–histology agreement for bone invasion was κ = 0.45, indicating moderate agreement. Conclusions: In this retrospective single-center cohort, the pattern of mandibular bone invasion was associated with survival: infiltrative invasion aligned with worse outcomes, whereas erosive behaved similarly to no invasion, particularly for OS. Prospective, multicenter validation is warranted before routine incorporation into risk stratification or treatment selection. Full article

Malignant peripheral nerve sheath tumors (MPNSTs) are rare sarcomas with an extremely rare perineurial subtype. Herein, we present a case of a perineurial MPNST in the cauda equina. Clinically and radiologically, a mass extending from within the spinal canal at the L5 level to outside the intervertebral foramen was identified, raising suspicion of a neurogenic tumor as the primary diagnosis. Computed tomography-guided biopsy suggested an intermediate- to low-grade malignancy; however, a definitive diagnosis could not be established. Two years later, worsening neurological symptoms prompted further imaging, which revealed significant tumor growth and bone invasion. Open biopsy was performed to obtain a definitive diagnosis of perineurial MPNST. MPNSTs lack distinctive imaging features and are generally diagnosed based on a combination of radiological and histopathological findings. Although MPNSTs have a poor prognosis, the perineurial subtype is considered to have a relatively favorable outcome. Given these factors, early diagnosis followed by surgical resection or radiation therapy is recommended. Full article
