Recurrence and metastasis of cutaneous and subcutaneous tumors following excision with advanced surgical margin assessment.

ABSTRACT:

Background

Surgical margin status can affect the risk for recurrence in dogs with cutaneous and subcutaneous masses. Histopathology is the current gold standard for margin assessment, despite evaluating small amounts of the surgical margin. Optical coherence tomography (OCT) has been described for surgical margin assessment following the excision of canine cutaneous and subcutaneous tumors.

Objective

To assess the rates of recurrence and metastasis following excision with an incomplete margin on OCT and confirmed with histopathology.

Animals and procedure

Seventy-one excised canine cutaneous and subcutaneous tumors underwent OCT imaging and histopathologic assessment.

Results

Of 61 tumors, 51 were malignant, including 21 soft tissue sarcomas and 21 mast cell tu
