Kaplan-Meier survival curves for dogs treated with no adjuvant therapy (heavy dashed line), surgery and chemotherapy (dashed line), surgery, radiation therapy and chemotherapy (solid line), and surgery and radiation therapy (Unequal dashed line). The MST for dogs treated with surgery alone, surgery, radiation therapy and chemotherapy, and surgery and radiation were 1393 days (range 20–1805 days), 730 days (170–2345 days), and 680 days (231–2077 days), respectively. More than a half of dogs treated with surgery and chemotherapy were censored and the MST was not calculated
