Metastatic cancer of unknown source in dogs

Metastatic carcinoma of unknown primary (MCUP) refers to a biopsy-proven malignancy in which the anatomical origin of the primary tumor cannot be detected after a thorough patient history, careful physical examination, and extensive clinical work up. In humans, only 20% of primary sites are identified by extensive diagnostic workup before the patients die. In approximately 70% of patients, the primary site cannot be identified even following necropsy.
