Diagnostic and prognostic yield of tumor markers in cancer of unknown primary site.
J Coll Physicians Surg Pak Jan ;16(2):154-6.

A case of metastatic carcinoma of unknown primary is reported that had widely disseminated disease from the very outset. Every effort was made to find out the primary by integrating all results and specially tumor markers. It was assumed that lung was the most possible site for primary. Tumor markers did not show their diagnostic value even in combined panel, they only showed their prognostic value.
