Overview
Pancoast tumor is a subtype of lung cancer located at the lung apex. There are no characteristic diagnostic lab findings associated with Pancoast tumor. The laboratory findings associated with lung cancer are the following neutropenia, hyponatremia, hypokalemia, hypercalcemia, respiratory acidosis, hypercarbia, hypoxia, and tumor cells in sputum and pleural effusion cytology.
Laboratory tests
There are no characteristic diagnostic lab findings associated with Pancoast tumor. The laboratory findings associated with lung cancer are the following:[1][2][3][4]
- Neutropenia in patients with a recent history of chemotherapy
- Hypercalcemia with normal PTH levels from squamous cell carcinoma (from secretion of parathyroid hormone-related peptide (PTH-rP)
- Arterial blood gas
- Sputum cytology demonstrates tumor cells
- Pleural effusion cytology demonstrates tumor cells
