Figure 5From: High prevalence of Y-box protein-1/p18 fragment in plasma of patients with malignancies of different origin YB-1/p18 during therapy in a patient with small cell lung cancer. Serum samples were obtained from a 45-year old male with small cell lung cancer at diagnosis (lane 1) and during chemotherapy with cisplatin/etoposide (lanes 2–3), initially with good response. He was found to progress in month 3 (lane 4), and then was treated with epirubicine, cyclophosphamide, and vincristine (lanes 5–7). Simultaneous measurements of NSE and PGRP are displayed. NSE and PGRP were the only two positive parameters of 13 tumor markers initially tested in this patient. The relative optical density (rel. OD) of the YB-1/p18 signal in immunoblotting is given.Back to article page
