Objectives. The clinical utility of routine cross sectional imaging of the
abdomen and pelvis in the screening and surveillance of patients
with primary soft-tissue sarcoma of the extremities for metastatic
disease is controversial, based on its questionable yield paired
with concerns regarding the risks of radiation exposure, cost, and
morbidity resulting from false positive findings. Methods. Through retrospective review of 140 patients of all ages (mean
53 years; 2 to 88) diagnosed with soft-tissue sarcoma of the extremity
with a mean follow-up of 33 months (0 to 291), we sought to determine
the overall incidence of isolated abdominopelvic metastases, their
temporal relationship to chest involvement, the rate of false positives, and
to identify disparate rates of metastases based on sarcoma subtype. Results. A total of four patients (2.9%) exhibited isolated abdominopelvic
metastatic disease during the surveillance period. In all cases
of concomitant chest and abdominopelvic disease, chest involvement
preceded abominopelvic involvement. There was a significant false
positive rate requiring invasive workup. Conclusions. In the setting of a relative paucity of evidence concerning a
rare disease process and in difference to recently published investigations,
we add a clinical cohort not supportive of routine cross sectional
imaging of the abdomen and pelvis. Cite this article: Bone Joint Res 2015;4:45–9
