Placental protein 10 (PP10) in the serum of patients with trophoblastic and nontrophoblastic gynaecological tumours.
Serum levels of placental protein 10 (PP10) were measured by radioimmunoassay in patients with trophoblastic (n = 23) and non-trophoblastic (n = 122) gynaecological tumours before, during and after treatment. Elevated levels (greater than 2.0 micrograms/l) were found in 96% of patients with an untreated trophoblastic tumour, and in 22%, 20% and 12% of patients with endometrial, cervical and ovarian carcinoma, respectively. After treatment the levels fell in patients with trophoblastic disease. Although PP10 may be tumour-associated in such cases, it is premature to assume any significance for PP10 as a tumour marker in clinical practice, because changes in serum hCG levels are much more informative.
