Objective: In the present study, we evaluated changes in CA-125 cut-off values predictive of complete interval debulking surgery (IDS) after neoadjuvant chemotherapy (NAC) using receiver operating characteristic (ROC) analysis. Methods: This retrospective single-institution study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage III epithelial ovarian cancer and a pre-NAC serum CA-125 level of greater than 40 U/mL who were treated with neoadjuvant platinum-based chemotherapy followed by IDS between 1994 and 2009. Logistic regression analysis was used to evaluate univariate and independent multivariate associations with the effect of clinical, pathological, and CA-125 parameters on complete IDS, and ROC analysis was used to determine potential cut-off values of CA-125 for prediction of the possibility of complete IDS. Results: Seventy-five patients were identified. Complete IDS was achieved in 46 (61.3%) patients and non-complete IDS was observed 29 (38.7%). Median pre-NAC CA-125 level was 639 U/mL (range, 57 to 6,539 U/mL) in the complete IDS group and 1,427 U/mL (range, 45 to 10,989 U/mL) in the non-complete IDS group. Median pre-IDS CA-125 level was 15 U/mL (range, 2 to 60 U/mL) in the complete IDS group and 53 U/mL (range, 5 to 980 U/mL) in the non-complete IDS group (p<0.001). Multivariate analyses performed with complete IDS as the endpoint revealed only pre-IDS CA-125 as an independent predictor. The odds ratio of non-complete IDS was 10.861 when the pre-IDS CA-125 level was greater than 20 U/mL. Conclusion: The present data suggest that in the setting of IDS after platinum-based NAC for advanced ovarian cancer, a pre-IDS CA-125 level less than 20 U/mL is an independent predictor of complete IDS.

Objective: The aim of the present study was to assess prognostic factors for patients with locally advanced cervical cancer treated with radiotherapy as the primary treatment and to assess the posttreatment cut-off levels of squamous cell carcinoma antigen (SCC-Ag) to predict three-year overall survival (OS) rates. Methods: One hundred and twenty-eight patients with cervical squamous cell carcinoma (International Federation of Gynecology and Obstetrics [FIGO] stage IIB-IVA) treated using radiotherapy or concurrent chemoradiotherapy were identified. Of these patients, 116 who had SCC-Ag levels >1.5 ng/mL prior to treatment were analyzed retrospectively. Results: Median age was 68 years (range, 27 to 79 years). The complete response rate was 70.7% and the three-year OS rate was 61.1%. The median levels of pretreatment and posttreatment SCC-Ag were 11.5 ng/mL (range, 1.6 to 310.0 ng/mL) and 0.9 ng/mL (range, 0.4 to 41.0 ng/mL), respectively. Multivariate analysis showed that pretreatment anemia (p=0.041), pelvic lymph node metastasis (p=0.016) and posttreatment SCC-Ag levels (p=0.001) were independent prognostic factors for three-year OS. The SCC-Ag level cut-off point for three-year OS rates, calculated using a receiver operating characteristic curve, was 1.15 ng/mL (sensitivity, 80.0%; specificity, 74.0%). Conclusion: Pretreatment anemia and pelvic lymph node metastasis are poor prognostic factors in locally advanced cervical cancer. Furthermore, posttreatment SCC-Ag levels <1.15 ng/mL predicted better three-year OS rates.

Cut-off value of D-dimer for prediction of deep venous thrombosis before treatment in ovarian cancer
Ryuji Kawaguchi,Naoto Furukawa,Hiroshi Kobayashi 대한부인종양학회 2012 Journal of Gynecologic Oncology Vol.23 No.2
Objective: The purpose of the present study was to elucidate the incidence of deep venous thrombosis (DVT) before treatment in ovarian cancer and the appropriate cut-off value of D-dimer (DD) for the diagnosis of DVT. Methods: Between July 2007 and October 2008, eighty seven patients with presumed ovarian cancer (final diagnosis: ovarian cancer, n=59; borderline malignancy, n=28) were enrolled. Measurement of DD levels and subsequent venous ultrasonography were performed before treatment. Results: The mean DD level was 4.1 μg/mL. Subsequent venous ultrasonography revealed DVT in 14 of 87 (16.1%) patients (ovarian cancer, 12 cases; borderline malignancy, 2 cases). None were found to have developed DVT if they had a DD level of <1.5 μg/mL. If 1.5 μg/mL was used as a cut-off value for DD levels to diagnose DVT, sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 61.6%, 33.3%, and 100%. There was noclinical onset of postoperative pulmonary thromboembolism. Conclusion: Our data suggest that presumed ovarian cancer patients with at least more than 1.5 μg/mL should be examined using venous ultrasonogaphy to detect DVT.
