Results
170 patients underwent biopsy and/or resection of a retroperitoneal mass,
of whom 44 (25.9%) patients went directly to surgical resection without a pre-surgical biopsy (Fig 1).
5/44 (11.4%) (p = 0.000974) patients would have had a change in clinical management if the histology of the mass was known prior to resection.
These 5 patients had on average a 7.6 (SD 6.4) day length of hospital stay and had on average a 40.3 (SD 25.7) day delay to receiving appropriate therapy (Table 1).
Two representative cases are shown in the accompanying figures where there was a delay in treatment with chemotherapy (Fig 3) and a case where surgical resection may not have been necessary (Fig 4).
Clinical management was appropriate in 15/15 (100 %) of patients with resected liposarcomas where biopsy was not performed (Fig 2).
