Abstract:
The establishment of new tumor marker combinations including strong lead-time effects in detecting recurrent cervical cancer appears to be warranted. This retrospective study includes 50 patients with recurrent squamous cell cervical cancer after operation or radiotherapy. The serial serum levels of the tumor markers tissue polypeptide specific antigen (TPS) and squamous cell carcinoma antigen (SCC) were determined. Cutoff values of 78.5 U/L for TPS and 1.5 microg/L for SCC were selected according to the 95th percentile of serum concentrations measured in healthy control patients. Comparing with other monitoring modalities, SCC and TPS showed lead-time effective in 27 and 30 cases, respectively. This difference was not statistically significant. The combination of SCC and TPS provided lead-time effects in 42 cases. Our data indicate that combination of TPS and SCC is a valuable tool in the early predicting recurrent cervical cancer.
