PURPOSE: To determine the relationship between pretreatment serum squamous cell carcinoma (SCC) antigen and Cyfra 21-1 levels, and survival in patients with invasive squamous cell carcinoma of the cervix. MATERIALS AND METHODS: One hundred and one cervical squamous cell carcinoma patients were included. Pre-treatment levels of serum SCC antigen and Cyfra 21-1 were measured, with a 5 year minimum follow up. Thirty two recurrent disease (RD) patients were compared to 99 non-recurrent disease (NRD) patients with respect to tumor markers, FIGO stage, lesion size, lymph node status, and parametrial involvement. RESULTS: Pre-treatment serum SCC antigen and Cyfra 21-1 levels were significantly higher in the RD group (p<0.001). Combined serum SCC antigen and Cyfra 21-1 levels showed higher sensitivity for prediction of recurrence (90.6%). Pre-treatment SCC antigen and Cyfra 21-1 levels showed correlation with high FIGO stage, large lesion size, lymph node status, and parametrial involvement (p<0.001). Normal pre-treatment levels of SCC antigen and Cyfra 21-1 showed a 5-year survival rate of 93% and 90% respectively, while elevated levels showed significantly decreased survival rate of 63% and 59%, respectively (p<0.001). Odd ratio for cumulative survival rates were 6.87 for SCC antigen, and 5.07 for Cyfra 21-1 (p<0.001). CONCLUSIONS: Initial pre-treatment levels of serum SCC antigen and Cyfra 21-1 are closely related to FIGO stage, lesion size, lymph node and parametrial involvement in patients with squamous cell carcinoma of the cervix. Also, these markers may be of help to predicting recurrent disease and survival rates.

PURPOSE: Peritoneal metastasis is a crucial factor for the prognosis in gastric cancer, but its diagnosis is difficult before laparotomy. This study analyzed the usefulness of diagnostic imaging and various tumor markers in the detection of peritoneal metastasis in gastric cancer. MATERIALS AND METHODS: The sera from 768 patients with gastric cancer were measured for CEA, CA19-9 and CA125 levels using a commercial immunoradiometric assay. All the patients underwent diagnostic imaging with computed tomography (CT) and ultrasound (US) before laparotomy. RESULTS: Preoperative levels of CEA, CA19-9 and CA125 were above the cut-off levels in 15.4%, 8.7% and 5.7% of all cases, respectively. Eighty-eight patients were diagnosed with peritoneal metastasis by laparotomy. CT and US revealed peritoneal dissemination in 15 of 88 patients (17%). Among the three tumor markers, CA19-9 and CA125 showed similar detection rates of peritoneal metastasis (37.5% and 38.6%, respectively). In particular, the serum CA125 levels showed the best sensitivity (38.6%), specificity (98.4%), and diagnostic accuracy (91.5%), and the highest odd ratio (24.46, 95% CI: 11.17~53.57) for predicting peritoneal metastasis among the markers tested. CEA did not add significant predictive information (p=0.471). CONCLUSION: Preoperative serum CA19-9 and CA125 levels may provide a predictable value in determining peritoneal metastasis in patients with gastric cancer.
