Soft-tissue Sarcoma Metastases Identified on Abdomen and Pelvis CT Imaging
The current standard of care for patients with extremity soft-tissue sarcomas is to obtain imaging of the chest for staging and surveillance. Our institutional standard of care has been to obtain CT scans of the chest, abdomen, and pelvis to evaluate for metastatic disease. Cost and radiation risk led us to question the utility of the additional scans. We presumed abdomen and pelvic CT scans would not benefit this patient population. We retrospectively reviewed our sarcoma databases from 2000 to 2008. We included 124 patients with 15 types of extremity soft tissue sarcomas evaluated with CT of the C/A/P. Primary outcomes were (1) location of metastatic disease in relation to (2) sarcoma type. Twenty patients (16%) presented with or developed abdomen/pelvis metastases and 10 of the 15 types of soft tissue sarcomas had abdominal or pelvic metastases. A larger number of patients demonstrated metastatic disease in the abdomen and pelvis than anticipated. We believe routine imaging of the abdomen and pelvic with CT for both staging and surveillance of all types of soft tissue sarcoma should be considered.
