BIRC5 and squamous cell carcinoma: It is important to note that in contrast to the present study’s survivin concentrations of 189 pg/mL [IQR: 62.5–512 pg/mL] in nasal carcinomas and 221.5 pg/mL [IQR: 143.5–321.8 pg/mL] in nasal sarcomas, higher maximum survivin concentrations were observed in dogs with malignant tumors in the cited study, such as, 104 pg/mL [IQR: 25–1,113 pg/mL] in dogs with adenocarcinomas of the mammary glands, 45 pg/mL [IQR: 10–658 pg/mL] in squamous cell carcinomas, and 93 pg/mL [IQR: 18–5,960 pg/mL] in dogs with soft-tissue sarcomas (28).
