Soft Tissue Tumors in Adults: ESSR-Approved Guidelines for Diagnostic Imaging

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Soft tissue sarcomas are rare but require prompt diagnosis and treatment for optimal clinical outcomes.
• Accurate diagnosis and staging are critical for effective management of soft tissue tumors.
• Existing guidelines assist radiologists and clinicians in decision-making for suspected soft tissue tumors.

Purpose of the Study:

• To provide evidence-based recommendations for the diagnostic and staging workup of soft tissue sarcomas.
• To guide radiologists in interpreting imaging findings and reporting requirements.
• To support interdisciplinary collaboration in sarcoma management.

Main Methods:

• Review of current literature and existing guidelines for soft tissue sarcoma diagnosis and staging.
• Recommendations for imaging modalities including ultrasound, magnetic resonance imaging (MRI), radiography, and CT chest.
• Emphasis on the role of biopsy and referral to specialist sarcoma centers.

Main Results:

• Potentially malignant lesions on ultrasound require MRI for staging.
• Radiography can identify matrix calcification and osseous involvement.
• Biopsy is recommended for indeterminate lesions, preferably at specialist centers with multidisciplinary teams.
• CT chest is mandatory for staging all sarcomas.
• Follow-up recommendations include regular monitoring for 10 years post-diagnosis, tailored to tumor grade.

Conclusions:

• Adherence to recommended imaging protocols and multidisciplinary team involvement improves soft tissue sarcoma management.
• Standardized reporting and biopsy procedures enhance diagnostic accuracy.
• Long-term follow-up, though not evidence-based, is suggested for surgically treated sarcomas based on tumor grade.
