Question

vertebral osteoblastic metastases of breast cancer are characterized by an elevation of serum: amylase alpha-1-antitrypsin alkaline phosphatase acid phosphatase

Explanation:

Osteoblastic metastases are associated with bone - forming activity. Alkaline phosphatase is an enzyme that is elevated in conditions with increased bone turnover, such as osteoblastic bone metastases from breast cancer. Amylase is related to pancreatic and salivary gland function, alpha - 1 - antitrypsin is involved in protecting against proteolytic enzymes, and acid phosphatase is mainly related to prostate and other tissues, not typically elevated in osteoblastic breast cancer metastases.

Answer:

C. alkaline phosphatase
