MRI surveillance after resection for primary musculoskeletal sarcoma

Area of Science:

• Oncology
• Radiology
• Orthopedic Surgery

Background:

• Musculoskeletal sarcomas require vigilant follow-up post-excision to monitor for recurrence.
• Magnetic Resonance Imaging (MRI) is a key modality in assessing soft-tissue and bone tumors.

Purpose of the Study:

• To evaluate the effectiveness and yield of routine surveillance MRI in detecting local recurrence after musculoskeletal sarcoma excision.
• To analyze the timing and method of recurrence detection (surveillance vs. interval scans).

Main Methods:

• Retrospective review of case notes, MRI, and histology reports for 57 patients treated for musculoskeletal sarcoma.
• Analysis of local tumor recurrence rates and detection methods via surveillance and interval MRI scans.

Main Results:

• A local recurrence rate of 22% (13 out of 57 patients) was observed.
• Nine recurrences were detected by routine surveillance MRI in asymptomatic patients.
• Four recurrences were identified by interval MRI in patients with clinical concerns.

Conclusions:

• Routine surveillance MRI plays a significant role in the early detection of local recurrence in patients with bone and soft-tissue sarcoma.
• Surveillance scanning demonstrates a cost-effectiveness in detecting recurrences, particularly when considering higher-grade tumors.
