Special Issue Information

Dear Colleagues,

Despite advances in the treatment of primary and metastatic tumors, clinical outcomes are still unfavorable. The majority of primary tumors have a poor response rate to chemotherapy and conventional radiotherapy, and lack the feasibility of oncologically appropriate surgical resection. The skeleton is the third most common site of metastases after the lungs and liver, with the spine being the most frequently affected bone. Metastatic spinal tumors often result in severe pain and neurological symptoms, reducing the performance status (PS). In metastatic tumor patients, a decrease in PS not only directly affects mortality, but also affect it indirectly by preventing the application of effective systemic therapies. Clinicians have a number of issues that need to be resolved and improved in the management and treatment of spinal tumors.

This Special Issue of Cancers aims to highlight recent advanced research on spine tumor which can improve the understanding of different assessments and/or innovative and personalized treatments for the management of primary and metastatic spinal tumors. Authors are encouraged to submit their original research, including systematic reviews and meta-analyses, clinical trials, observational studies, case series study and experimental work which presents recent advances in the management and treatment of spinal tumors.

Background/Objectives: Massive intraoperative blood loss (IBL) is one of the major complications in metastatic spinal tumor surgery (MSTS), and understanding the predictors of this risk is essential. This study aimed to determine the impact of the intratumoral flow void (IFV) observed on standard magnetic resonance imaging (MRI) and its association with IBL in palliative surgery for metastatic spinal tumors. Methods: This retrospective analysis included 88 palliative excisional surgeries performed at a single hospital between 2010 and 2024. Factors such as age, sex, body mass index, tumor location, histological tumor type, spinal instability neoplastic score, revised Tokuhashi score, preoperative radiation, presence of IFV, and IFV diameter were assessed in addition to surgical details such as the number of resected and instrumented vertebrae and surgical duration. Results: Of the 88 patients, 71 (80.7%) exhibited IFV, with a mean IFV diameter of 1.8 ± 1.3 mm. The univariate analysis identified a significant association between IBL and several factors, including the presence of IFV, IFV diameter, hypervascular tumor type, number of instrumented vertebrae, and surgical duration. The multivariate analysis indicated that IFV diameter had the highest standardized coefficient among the examined variables, suggesting its strong potential as a predictor of IBL. Conclusions: This is the first study to identify the IFV diameter as a critical and independent predictor of IBL in MSTS. IFV diameter, which can be easily assessed using standard MRI, should be considered in surgical planning to effectively manage bleeding. Full article

Introduction: Spinal intradural tumors account for 15% of all CNS tumors. Typical tumor entities include ependymomas, astrocytomas, meningiomas, and neurinomas. In cases of multiple affected segments, extensive approaches may be necessary to achieve the gold standard of complete tumor resection. Methods: We performed a bicentric, retrospective cohort study of all patients equal to or older than 14 years who underwent multi-segment surgical treatment for spinal intradural tumors between 2007 and 2023 with approaches longer than four segments without instrumentation. We assessed the surgical technique and the clinical outcome regarding signs of symptomatic spinal instability. Children were excluded from our cohort. Results: In total, we analyzed 33 patients with a median age of 44 years and interquartile range IQR of 30–56 years, including the following tumors: 21 ependymomas, one subependymoma–ependymoma mixed tumor, two meningiomas, two astrocytomas, and seven patients with other entities. The median length of the approach was five spinal segments with a range of 4–14 and with the foremost localization in the cervical or thoracic spine. Laminoplasty was the most chosen approach (72.2%). The median time to follow-up was 13 months IQR (4–56 months). Comparing pre- and post-surgery outcomes, 72.2% of the patients (n = 24) reported pain improvement after surgery. The median modified McCormick scores pre- and post surgery were equal to II IQR (I–II) and II IQR (I–III), respectively. Discussion: We achieved satisfying results with long-segment approaches. In general, patients reported pain improvement after surgery and received similar low modified McCormick scores pre- and post surgery and did not undergo secondary dorsal fixation. Thus, we conclude that intradural tumor resection via extensive approaches does not seem to impair long-term spinal stability in our cohort. Full article

Spinal metastases occur in up to 40% of patients with cancer. Of these cases, 10% become symptomatic. The reported incidence of spinal metastases has increased in recent years due to innovations in imaging modalities and oncological treatments. As the incidence of spinal metastases rises, so does the demand for improved treatments and treatment algorithms, which now emphasize greater multidisciplinary collaboration and are increasingly customized per patient. Uniquely, we discuss the potential clinical applications of AI and NGS in the treatment of spinal metastases. Material and Methods: A PubMed search for articles published from 2000 to 2023 regarding spinal metastases and artificial intelligence in healthcare was completed. After screening for relevance, the key findings from each study were summarized in this update. Results: This review summarizes the evidence from studies reporting on treatment modalities for spinal metastases, including minimally invasive surgery (MIS), external beam radiation therapy (EBRT), stereotactic radiosurgery (SRS), CFR-PEEK instrumentation, radiofrequency ablation (RFA), next-generation sequencing (NGS), artificial intelligence, and predictive models.
