INTRODUCTION: Up to 40% of all initial operations for soft tissue sarcoma (STS) are unplanned, which would leave residual macroscopic tumor in more than 50% of the cases. The effect this has on local recurrence rate, metastases rate and survival has never been fully established, due to the lack of randomized studies. METHODS: Retrospective review of patients with STS treated in our unit between January 2001-January 2016. We classified them whether they had been treated by initial planned or unplanned operation. Outcomes were compared in both groups globally and stage-matched. Endpoints were local recurrence and distant metastases. RESULTS: Twenty-three patients of STS underwent a planned excision and 16 an unplanned excision, 13 of them underwent further re-excision. 40% of patients with planned excision had an advanced stage in regard to the unplanned excision group which presented earlier stages. 77% of patients with unplanned excision had residual tumor identified after surgical re-excision. Local recurrence rate in the unplanned excision group was considerably higher 73,5% vs. 43,8%. Metastases rate was lower in planned excision group, 45,5% vs 56,3% (P > .05). The recurrence pattern in the unplanned excision group was unstable, with worse outcomes in earlier stages. CONCLUSION: The unplanned excision of a soft tissue sarcoma may compromise disease local control, with higher rates of local recurrence and metastases, and worse functional out- comes, despite further oncological treatment. We need to recognize the clinical features for malignancy risk in soft tissue lumps for a safe diagnosis to avoid inadequate resections.
