Overview
Other diagnostic studies for cancer of unknown primary that may help establish the origin of the tumor include tumor markers, diagnostic tonsillectomy, and gastrointestinal endoscopy.
Other Diagnostic Studies
Other diagnostic studies for cancer of unknown primary that may help establish the origin of the tumor include:
- Tumor markers such as αFP, βHCG, PSA, CA125, CA 27.29, CA 19.9, and CEA[1]
- αFP and βHCG must be tested in patients presenting with midline metastatic disease.[2]
- PSA must be tested in patients presenting with adencarcinomatous bone metastases.[2]
- Diagnostic tonsillectomy[3]
- Gastrointestinal endoscopy, ENT panendoscopy (which is a combination of laryngoscopy, esophagoscopy, and bronchoscopy), proctoscopy, and colposcopy[4][5]
- Octreoscan and plasma chromogranin A
- In patients with neuroendocrine tumors
