Accurate soft tissue sarcoma (STS) imaging is crucial for treatment planning and follow-up. Contrast-enhanced CT is a valuable tool for STS, offering comparable planning ability to MRI for limb-sparing surgery.

Area of Science:

  • Oncology
  • Radiology
  • Surgical Planning

Background:

  • Effective management of soft tissue sarcoma (STS) relies on precise tumor imaging for accurate staging, treatment strategy, and patient follow-up.
  • Inadequate preoperative planning can lead to suboptimal primary resections, increasing the likelihood of repeat surgeries, local recurrence, and reduced survival rates.

Purpose of the Study:

  • To highlight the critical role of advanced imaging techniques in the comprehensive management of soft tissue sarcomas.
  • To compare the utility of Magnetic Resonance Imaging (MRI) and contrast-enhanced Computed Tomography (CT) in surgical planning for STS.

Main Methods:

  • Review of imaging modalities for soft tissue sarcoma (STS) staging and treatment planning.
  • Evaluation of contrast-enhanced Computed Tomography (CT) as an alternative to MRI for extremity STS.

  • Assessment of double contrast-enhanced CT for retroperitoneal and intra-abdominal STS, including metastasis detection and surgical margin assessment.

    • Main Results:

    • MRI is often preferred for extremity STS, but contrast-enhanced CT provides equivalent efficacy for operative strategy planning in limb-sparing resections.
    • Contrast-enhanced CT is highly effective for intra-abdominal STS, aiding in the evaluation of liver metastases and identification of critical structures for en bloc resection.
    • CT imaging is vital for defining at-risk margins and identifying adjacent organs susceptible to radiation toxicity.

    Conclusions:

    • Accurate preoperative imaging is essential for optimizing surgical outcomes and minimizing complications in soft tissue sarcoma (STS) management.
    • Contrast-enhanced CT is a versatile and effective imaging modality for both extremity and intra-abdominal STS, comparable to MRI in surgical planning.
    • Long-term postoperative surveillance, including imaging, is necessary due to the persistent risk of late relapse in STS patients.
