[A clinical study on multiple tumor markers following therapy in patients with uterine cervical carcinoma]

In order to evaluate the clinical significance of multiple tumor markers, plasma levels of carcino-embryonic antigen (CEA), squamous cell carcinoma-related antigen (SCC), tissue polypeptide antigen (TPA) and immunosuppressive acidic protein (IAP) were measured before and after treatment in 136 patients (89 surgery cases and 47 radiotherapy cases). The patients had invasive cervical carcinoma (stages I-IV). The effect of radiotherapy was examined by cytology and biopsies obtained by colposcopy. For CEA, SCC and TPA there was a significant reduction (p less than 0.01) in values between the pretreatment and posttreatment periods, but plasma IAP was transiently increased after operation. Cytology and histology revealed negative rates of 95.6% and 86.7%, respectively, after radiotherapy. Regarding recurrence, for the negative groups and positive groups plasma CEA, SCC, TPA and IAP were determined in 24 patients with stage IIIb before radiotherapy. Only the CEA concentration showed a good correlation with the outcome (p less than 0.01). Effective serial plasma determinations of CEA, SCC and TPA in patients with cervical carcinoma following therapy may often be useful in the evaluation of therapy as well as in the earlier detection of recurrent disease.
