Surgical resection of primary soft-tissue sarcoma - Incidence of residual tumour in 95 patients needing re-excision after local resection

We reviewed retrospectively 236 consecutive patients seen in our soft-tissue sarcoma clinic, Of these, 95 had had a primary soft-tissue sarcoma excised elsewhere, but with histologically inadequate resection margins, All these patients had a secondary and wider re-excision, The tissues removed at the secondary re-excision were examined histologically for the presence of residual tumour, Definite tumour tissue aas found in 29 of 55 lower-limb specimens, 16 of 25 upper-limb, 7 of 10 trunk and 4 of 5 head and neck specimens, In 31 cases some residual tumour was visible macroscopically, and in 56 of the 95 patients (59%) the primary tumour had been incompletely excised. Our results indicate that surgical assessment of the adequacy of excision is vers inaccurate and that most local recurrences are the consequence of inadequate primary surgery, The large number of patients who had inadequate initial treatment emphasises the need for a co-ordinated multidisciplinary approach to the management of patients with soft-tissue sarcoma.
