Elevated labs with breast cancer include which of the following?

Elevated labs with breast cancer include which of the following?

• A. Alkaline phosphatase and calcium
• B. AST and ALT
• C. Lipase and amylase
• D. Sodium and potassium

Answer: (A)

In breast cancer, bone metastases are common and drive increased bone turnover. Alkaline phosphatase is produced by osteoblasts, so when bone remodeling accelerates from metastatic involvement or healing, alkaline phosphatase levels rise. Calcium can become elevated because tumor-related bone destruction or humoral factors (like PTH-related peptide) disrupt calcium homeostasis, leading to hypercalcemia. This combination—alkaline phosphatase elevated due to bone turnover and calcium elevated due to bone metastasis–related processes—is a classic pattern seen with advanced breast cancer. The other lab pairs aren’t as specifically tied to the disease pattern. AST and ALT point more toward liver involvement or hepatotoxicity, lipase and amylase relate to pancreatic enzymes, and sodium and potassium are general electrolytes without the same diagnostic implication for metastatic breast cancer.
