What the literature leaves open

  • The lack of understanding of the prognostic and therapeutic considerations for oligometastatic GIST. The need to investigate the impact of treatment modalities and metastatic distribution on overall survival in patients with oligometastatic GIST.

    Oligometastatic GIST: Impact of Treatment Modalities and Metastatic Distribution on Overall Survival · 2026 · DOI

  • The detection and characterization of bone metastases on MRI can be time-consuming and challenging. There is a need for automated methods to improve the detection and classification of bone metastases. The study identifies a gap in the current literature, with substantial heterogeneity in study design, datasets, and validation strategies.

    Artificial Intelligence for Detection and Characterisation of Bone Metastases on MRI: A Scoping Review · 2026 · DOI

  • The study needs to address the potential bias from crossing curves in the Kaplan-Meier analysis.

  • The lack of effective treatments for pathologic fractures of the humerus that can provide rapid pain relief and functional recovery. The need for a minimally invasive treatment option that can reduce treatment-related morbidity. The limited understanding of the safety and efficacy of photodynamic intramedullary stabilization in this patient population.

    Photodynamic Bone Stabilization in Pathologic Humeral Fractures: Implant Safety, Pain Relief and Functional Outcomes · 2026 · DOI

  • Elderly patients with spinal metastases are often considered poor candidates for aggressive local therapy, due in part to medical comorbidity and limited evidence to guide treatment selection.

  • No studies have investigated the direct clinical benefits of hydrodissection in spinal tumor cryoablation.

    Saline Hydrodissection Does Not Markedly Alter Local Temperatures in Percutaneous Transpedicular Cryoablation · 2025 · DOI

  • While traditional, pain-relieving short-course regimens have been studied comprehensively, real-world SBRT results are still limited.

  • Optimal selection criteria remain to be determined, but in current clinical practice we exclude patients with poor performance status, unfavorable blood test results (high LabBM score) and progressive disease sites not amenable to SBRT.

    Stereotactic radiotherapy for patients with bone metastases: a selected group with low rate of radiation treatment during the last month of life? · 2024 · DOI

  • Single-fraction 8-Gy radiotherapy seemed to be a promising treatment option for painful non-bone-metastasis tumors and warrants further investigation.

    Pain response in single-fraction 8-Gy radiotherapy for painful non-bone-metastasis tumors: a single-center retrospective study · 2024 · DOI

  • However, the extent of lymphopenia caused by palliative radiotherapy and its effect on patient prognosis has not been clarified.

    Lymphopenia after palliative radiotherapy for vertebral metastases · 2024 · DOI

  • In conclusion, overall, compliance rates were high; however, for many QIs, practice remains to be improved in at least some centers.

    Quality of palliative radiotherapy assessed using quality indicators: a multicenter survey · 2024 · DOI

  • However, there is a noted gap in research on the rate and characteristics of subsequent SREs requiring further localized treatment, obligating clinicians to extrapolate from experiences with initial SREs when confronting subsequent ones.

  • The implementation of these tools into clinical practice warrants further investigation and confirmation through subsequent studies with separate databases.

  • There is a lack of accurate prognostic data and survival estimates for patients with bone metastases. Prior studies have not fully considered the importance of body composition measurements in patients with long-bone metastases.

    Prognostic factors for patients undergoing surgery for femur metastases following systemic treatment · 2026 · DOI

  • The lack of standard integration of specialist palliative care into oncological care. The reactive nature of referrals to specialist palliative care.

    Timely Integration of specialist palliative care into oncology care for patients receiving radiotherapy for bone metastases: A study procotol for the TIPZO-RT Randomized Controlled Trial · 2026 · DOI

  • Outcome patterns for stereotactic body radiotherapy (SBRT) of bone oligometastases (BoM) especially for older patients are inadequately defined.

    Outcomes of stereotactic body radiotherapy for bone oligometastases in older patients − A European multicenter cohort study · 2026 · DOI

  • Blood loss was quantified in 7 ways (including the formula from the development study) as no gold standard exists, and the method in the development paper was not clearly defined.

    External validation of a machine learning prediction model for massive blood loss during surgery for spinal metastases: a multi-institutional study using 880 patients · 2025 · DOI

  • Management of Metastatic Humeral Disease is based on a systematic review of published studies surrounding the management of metastatic disease, multiple myeloma, and lymphoma limited to the humerus.

    The Musculoskeletal Tumor Society Clinical Practice Guideline on the Management of Metastatic Humeral Disease · 2024 · DOI

  • The binary application of SINS may overlook biomechanical and tumor-type-specific subtleties.

    Comment on "Analysis of skeletal-related events in a liaison treatment for metastatic spinal tumors: A 10-year retrospective study" · 2026 · DOI

  • The integration of specialist palliative care into oncological care is not standard. Referrals are typically reactive, only when situations are complex, hindered by several barriers for both clinicians and patients.

    Timely Integration of specialist palliative care into oncology care for patients receiving radiotherapy for bone metastases: A study procotol for the TIPZO-RT Randomized Controlled Trial · 2026 · DOI

  • Pseudoprogression was defined as equivocal radiology report for progression or MRI findings with transient growth that subsequently ceased on follow-up MRI without further interventions or treatments. Classification relied exclusively on the radiology report for some cases. Disagreement with radiology reports or across reviewers was reviewed to reach a consensus.
