The diagnostic performance of CA 125, CT scan and combination of CA 125 with CT scan in extra-uterine extension, including intra-abdominal lymph node metastasis in apparently early-staged endometrial cancer patients.

The association between the serum levels of cancer antigen 125 (CA125; also termed MUC16) and the prognosis of patients with hepatocellular carcinoma (HCC) has not been widely reported to date. The aim of the present study was to determine the association between preoperative serum CA125 levels and prognosis of patients with hepatitis B virus (HBV)-related HCC after hepatectomy. The study included 306 patients with HBV-related HCC who underwent liver resection and were classified into four subgroups based on their baseline CA125 and α-fetoprotein (AFP) levels. The perioperative clinical data were compared and analyzed. Kaplan-Meier and Cox regression analyses were performed to determine the associations between patient clinicopathological characteristics and survival. The results revealed that the median follow-up time was 35 months. Patients with low preoperative serum CA125 levels presented with improved 3-year disease-free survival (DFS) (79.3 vs. 75.7%; P=0.278) and overall survival (OS) (84.4 vs. 77.1%; P=0.001) rates compared with those among patients with high preoperative serum CA125 levels. High preoperative serum CA125 levels were a risk factor associated with short DFS and OS rates in all patients. In patients with baseline AFP levels >100 ng/ml, low preoperative serum CA125 levels were significantly associated with prolonged DFS and OS rates (log-rank test P=0.002 and P=0.005, respectively). In patients with AFP levels ≤100 ng/ml, no significant differences were observed in DFS or OS rates between the high and low preoperative serum CA125 groups. Patients with high preoperative serum CA125 and AFP levels exhibited the worst prognosis (low DFS and OS rates). In conclusion, high baseline CA125 levels may be associated with a poor prognosis in patients with HBV-related HCC.

Objective : To evaluate the ability of preoperative serum CA-125 level to predict the outcome of primary cytoreductive surgery in patients with epithelial ovarian carcinoma. Methods : We performed a retrospective chart review of 85 consecutive patients with epithelial ovarian carcinoma. All patients had preoperative serum CA-125 levels measured. We used a receiver operating characteristics curve (ROC) to determine the CA-125 level with the maximal power in predicting the outcome of primary cytoreductive surgery. Results : The median CA-125 level was 890.9 U/mL for all patients. Preoperative CA-125 level had significant correlations with histology, tumor grade, stage, and the presence of ascites (p<0.05). Also, preoperative CA-125 level showed significant difference between patients with suboptimal cytoreduction and those with optimal cytoreduction (2584.9 U/mL vs. 524.8 U/mL, p<0.05). Using the ROC, we found that preoperative CA-125 level of 1050 U/mL had the most powerful ability in predicting the outcome of primary cytoreductive surgery, but a poor negative predictive value (sensitivity 66.7%, specificity 64.0%, PPV 81.6%, NPV 44.4%). Optimal cytoreductive surgery was achieved in 81.6% (40/49) among patients with CA-125 <1050 U/mL, but 55.6% (20/36) among those with CA-125=1050 U/mL (p<0.05). Conclusion : We think that preoperative CA-125 level may be used for selection of candidates for neoadjuvant chemotherapy before primary cytoreductive surgery. But preoperative CA-125 level was a weak negative predictor of primary optimal cytoreductive surgery. Thus, preoperative CA-125 level could not be a primary predictor of the outcome of primary cytoreductive surgery and should be considered in the context of other preoperative features.

Can serum CA-125 levels predict the optimal primary cytoreduction in patients with advanced ovarian carcinoma?

Twenty-eight patients with histologically proven pancreatic adenocarcinoma were investigated to evaluate the utility of serum CA19-9 levels as a prognostic indicator after pancreatic resection. Three patients were excluded from the study because their serum CA19-9 levels remained normal throughout the course of the disease. Of the remaining 25 patients, those with preoperative serum CA19-9 levels ≤200U/ml had a better prognosis than those with serum CA19-9 levels >200 U/ml; however, the difference between the two groups was not significant (P=0.13). Serum CA19-9 levels 30 days after pancreatic resection were normalized (≤37 U/ml) in 11 patients (group A), and the survival rate of this group was significantly higher than that of the group of patients with persistently elevated CA19-9 levels (>37 U/ml) (group B) (P<0.005). Other factors i.e., preoperative CA19-9 values, tumor size, lymph node metastasis, histology, and stage classification showed no significant differences between group A and group B. Univariate analysis of the findings for the 25 patients showed that the stage classification and postoperative CA19-9 levels were of prognostic significance for prolonged survival. Other factors, i.e., gender, age, histology, preoperative CA19-9 levels, location of the tumor, and mode of operation, had no significance as prognostic indicators. Multivariate analysis showed that postoperative CA19-9 level was the only significant independent predictor of poor survival. Postoperative serum CA19-9 level appears to be useful as a prognostic indicator after resection of pancreatic cancer.

To evaluate the prognostic significance of preoperative CA-125 levels on overall survival of patients with International Federation of Gynecology and Obstetrics (FIGO) stage I epithelial ovarian cancer (EOC). Data from 518 patients with FIGO stage I EOC treated in seven gynecologic oncology centers throughout Australia between 1990 and 2002 were analyzed. Patients with borderline tumors and nonepithelial ovarian carcinomas were excluded, as were women in whom CA-125 had not been determined preoperatively. Preoperative CA-125 levels were studied in surgically staged and incompletely staged patients and compared with prognostic factors, such as substage, grade, and histologic type. Multivariate Cox models were calculated. CA-125 levels more than 30 U/mL were associated with higher grade, substage 1B and 1C, nonmucinous histologic type, and older age. In univariate analysis, higher histologic grade, the absence of surgical staging, and preoperative CA-125 levels more than 30 U/mL were associated with impaired survival. Multivariate analysis identified histologic grade, preoperative CA-125, and surgical staging as independent predictors for survival. In the subgroup of completely surgically staged patients, the 5-year overall survival rate was 82% (95% CI, 76% to 88%) for patients with CA-125 levels more than 30 U/mL and 95% (95% CI, 90% to 99%) for patients with CA-125 levels of 30 U/mL or less (P = .028). In the group of incompletely staged patients, the 5-year survival rates were similar for patients with elevated and normal serum CA-125 levels. Complete surgical staging, histologic grade, and preoperative serum CA-125 levels are independent prognostic factors and should be included in the decision making for chemotherapy.

ObjectiveThe aim of this study is to establish a noninvasive preoperative model for predicting primary optimal cytoreduction in advanced epithelial ovarian cancer by HE4 and CA125 combined with clinicopathological parameters.MethodsClinical data including preoperative serum HE4 and CA125 level of 83 patients with advanced epithelial ovarian cancer were collected. The sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of each clinical parameter were calculated. The Predictive Index score model and the logistic model were constructed to predict the primary optimal cytoreduction.ResultsOptimal surgical cytoreduction was achieved in 62.65% (52/83) patients. Cutoff values of preoperative serum HE4 and CA125 were 777.10 pmol/L and 313.60 U/ml. (1) Patients with PIV ≥ 6 may not be able to achieve optimal surgical cytoreduction. The diagnostic accuracy, NPV, PPV and specificity for diagnosing suboptimal cytoreduction were 71, 100, 68, and 100%, respectively. (2) The logistic model was: logit p = 0.12 age − 2.38 preoperative serum CA125 level − 1.86 preoperative serum HE4 level-2.74 histological type-3.37. AUC of the logistic model in the validation group was 0.71(95%CI 0.54–0.88, P = 0.025). Sensitivity and specificity were 1.00 and 0.44, respectively.ConclusionAge, preoperative serum CA125 level and preoperative serum HE4 level are important non-invasive predictors of primary optimal surgical cytoreduction in advanced epithelial ovarian cancer. Our PIV and logistic model can be used for assessment before expensive and complex predictive methods including laparoscopy and diagnostic imaging. Further future clinical validation is needed.

To evaluate the relationship between pre-operative CA-125 levels and myometrial invasion in patients with early-stage endometrioid-type endometrial cancer. Two-hundred and sixty patients were diagnosed with endometrial cancer between January 2007 and December 2012. Of these, 136 patients with stage 1 endometrioid histologic-type and documented pre-operative serum CA-125 levels were included in the study. Age, preoperative CA-125 level, histologic grade, surgical grade, and presence of deep myometrial invasion were recorded. Additionally, 16, 20, and 35 IU/ml cutoff values were used and compared to evaluate the relationship between pre-operative CA-125 levels and myometrial invasion. The average serum CA-125 level was 35.4±36.7 in patients with deep myometrial invasion, and 21.5±35.8 in cases without deep myometrial invasion. The relationship between the presence of deep myometrial invasion and CA-125 cut-off values (16, 20, 35 IU/ml) was statistically significant, although the correlation was weak (p<0.05). When the relationship between 16, 20 and 35 IU/ml CA-125 cut-off values and the presence of deep myometrial invasion was studied, specifity and sensitivity values were identified as: 0.60-0.68 for 16 IU/ml; 0.73-0.48 for 20 IU/ml; and 0.89-0.33 for 35 IU/ml. The sensitivity of 16 IU/ml cut-off value was higher when compared to other values. This study demonstrates that preoperative serum CA-125 values maybe used as a predictive test in patients with early stage endometrioid-type endometrium cancer, and as a prognostic factor alone. Further studies should be conducted to identify different CA-125 cut-off values in patients with low risk endometrial cancer.

To explore the clinical significance of preoperative serum CEA, CA125, and CA19-9 levels in predicting the resectability of cholangiocarcinoma. Patients with cholangiocarcinoma diagnosed by radiologic examination and admitted to the Second Affiliated Hospital of Harbin Medical University from September 1, 2011, to November 30, 2017, were retrospectively included. The relationship between the preoperative serum CEA, CA125, and CA19-9 levels and the resectability of cholangiocarcinoma was analyzed by receiver operating characteristic (ROC) curve, as well as the best cut-off point. A total of 112 met the inclusion criteria. In 50 patients with radical surgeries, the levels of preoperative serums CEA, CA125, and CA19-9 were 5.0 ± 13.9 ng/mL, 15.3 ± 11.8 U/mL, and 257.5 ± 325.6 U/mL, respectively, which were lower than those in patients with unresectable tumor. Based on the ROC curve, the ideal CA19-9 cut-off value was determined to be 1064.1 U/mL in prediction of resectability, with a sensitivity of 53.2%, a specificity of 94.0%, and the area under the ROC curve of 0.73 (P < 0.05). The cut-off value of CA125 was 17.8 U/mL with a sensitivity of 72.6%, a specificity of 78.0%, and the area under the ROC curve of 0.81 (P < 0.05). The cut-off value of CEA was 2.6 ng/mL with a sensitivity of 79.0%, a specificity of 48.0%, and the area under the ROC curve of 0.66 (P < 0.05). In addition to this, we found that using the combination of three tumor markers could improve the value in predicting resectability of cholangiocarcinoma. In summary, this study suggested that the preoperative serum CEA, CA125, and CA19-9 levels can help predict the resectability of cholangiocarcinoma.

Value of preoperative serum CA125 in early-stage adenocarcinoma of the uterine cervix without pelvic lymph node metastasis

To determine the prognostic importance of pleural effusions on preoperative computed tomographic (CT) images in patients with advanced epithelial ovarian cancer. The institutional review board waived informed consent for this HIPAA-compliant study of 203 patients with International Federation of Obstetrics and Gynecology stage III (n = 172) or IV (n = 31) epithelial ovarian cancer who underwent CT before primary cytoreductive surgery between 1997 and 2004 (mean age, 61 years; range, 37-96 years). Two radiologists retrospectively evaluated chest and/or abdominal CT images for pleural malignancy and the presence, size, and laterality of pleural effusions. To evaluate survival, Kaplan-Meier methods were used, with log-rank P values for comparisons. Multivariate analyses were conducted by using Cox proportional hazards regression. κ Statistics were calculated for interreader agreement. Median survival was 50 months (95% confidence interval [CI]: 45, 55 months) for patients with stage III disease and 41 months (95% CI: 27, 58 months) for patients with stage IV disease. Readers 1 and 2 found pleural effusions in 40 and 41 stage III and 20 and 21 stage IV patients, respectively. At multivariate analysis, after controlling for stage, age at surgery, preoperative serum CA-125 level, debulking status, and ascites, moderate-to-large pleural effusion on CT images was significantly associated with worse overall survival (reader 1: hazard ratio = 2.27 [95% CI: 1.31, 3.92], P < .01; reader 2: hazard ratio = 2.25 [95% CI: 1.26, 4.01], P = .02). Preoperative CA-125 level, debulking status, and ascites were also significant survival predictors (P ≤ .03 for all for both readers). Readers agreed substantially in distinguishing small from moderate-to-large effusions (κ = 0.764). Moderate-to-large pleural effusion on preoperative CT images in patients with stage III or IV epithelial ovarian cancer was independently associated with poorer overall survival after controlling for age, preoperative CA-125 level, surgical stage, ascites, and cytoreductive status.

ObjectiveMuch of the early investigative work on the usefulness of preoperative serum CA-125 levels in identifying patients with early-stage endometrial carcinoma who have occult metastases were carried out in Europe and the United States. This article reviews CA-125 as a possible index for determining the need for full surgical staging, from the results of large medical centers in Asia, particularly Taiwan and Korea.MethodsA Medline search was performed using CA-125 and endometrial cancer as index words from 1981 to 2012. Those publications felt to be the most important especially from institutions from Asia since 2000 were identified in this review.ResultsMost articles that analyzed the utility of serum CA-125 levels as predictive marker for disease extent or prognosis in uterine cancer used univariate and multivariable logistic regression analysis, and performed receiver operative curves to find the best cut-off values. The main factor of interest was whether clinicians can stratify patients that need lymphadenectomy in early stage disease. Suggested optimal cut-off value ranged from 20 to 210 U/mL. Not only preoperative CA-125 level, but myometrial invasion status by magnetic resonance imaging was the most significant combined parameter for predicting disease extent.ConclusionElevated CA-125 in patients with apparent early-stage disease is clearly a risk factor for the presence of extra-uterine disease although the optimal cut-off levels vary. The evolution of clinical investigations over the past decade, particularly in Asia, suggests employment of the test in a more focused manner to identify high risk patients preoperatively.

To investigate preoperative serum CA-125 levels as a predictive factor for evaluation of lymph node metastasis in epithelial ovarian cancer. Retrospective study. Medical records at Seoul National University Hospital. Ninety-nine patients with epithelial ovarian cancer between January 2004 and March 2007. The significance of the preoperative serum CA-125 level for the prediction of lymph node metastasis was determined using the receiver operating characteristic (ROC) curve, McNemar's test and logistic regression analysis. Clinical prognostic factors affecting survival were evaluated using the Kaplan-Meier analysis with the log-rank test and Cox's proportional hazard analysis. The ROC curve showed the best cut-off value (535 U/mL) of the preoperative serum CA-125 level with regard to sensitivity (70.0%) and specificity (83.1%). Imaging studies combined with the preoperative serum CA-125 level showed the highest sensitivity (90.0%), whereas imaging studies alone showed the highest specificity (89.8%) for the prediction of lymph node metastasis. FIGO stage III-IV, the preoperative serum CA-125 level (> or =535 U/mL) and lymph node involvement on imaging studies were significant factors for the prediction of lymph node metastasis (p<0.05). Suboptimal debulking surgery and lymph node metastasis were poor prognostic factors for progression-free survival and overall survival, respectively (p<0.05). The preoperative serum CA-125 level (> or =535 U/mL) may be important for the prediction of lymph node metastasis in patients with epithelial ovarian cancer. Furthermore, it can be helpful in selecting patients who should undergo systemic lymphadenectomy for the detection of hidden lymph node metastasis.

In Brief Objective: The aim of this study was to evaluate properative serum levels of CA-125 for the prediction of advanced stages of endometrial cancer. Method: Retrospective study evaluated 114 women with pathologically proven endometrial carcinoma treated in our institution that had preoperative serum CA-125 levels between January 1990 and December 2005. The association of preoperative serum CA-125 with a different histopathologic factors was evaluated. Statistical analysis was performed using Mann-Whitney U test and Kruskal-Wallis test and a logistic regression. Results: Elevated serum CA-125 levels were significantly correlated with advanced-stage disease, lymph node metastases, increased depth of myometrial invasion (P < 0,01). Similar correlation was seen between levels of CA-125 and positive peritoneal washing cytology, distant metastases and highest histologic grade. Multivariate analyses using logistic regression showed that lymph node metastases had the most significant effect on the elevation of preoperative serum CA-125 levels. Conclusion: The preoperative serum CA-125 level appears to be a significant independent predictor of advanced-stage disease and lymph node metastasis. Therefore, preoperative serum CA-125 may be a useful tool, in the clinical setting, for optimal individualized patient management. A CA-125 level should be included as a part of the preoperative workup for all patients with endometrial cancer. Preoperative serum CA-125 may be a useful tool, in the preoperative workup for all patients with endometrial cancer.

The aim of our study was to find preoperative or intraoperative pathologic indicators that would discriminate a subgroup of early corpus cancers that would not require lymphadenectomy. A retrospective review of the medical records of 107 patients with endometrioid adenocarcinoma, FIGO grade 1 or 2 tumor, myometrial invasion ≤50%, and no intraoperative evidence of macroscopic extrauterine spread was performed. Clinicopathologic risk factors were analyzed with Fisher ′s exact test with regards to pelvic lymph node metastasis. The median age of the patients was 54 years. Pelvic lymph node metastasis was observed in five of 107 patients (4.7%), where two patients with small tumors of 2 cm or less had positive pelvic lymph nodes. The presence of positive pelvic lymph nodes did not correlate with depth of invasion, histologic grade, cervical invasion, peritoneal cytology, menopausal status, preoperative serum CA125 level, or primary tumor diameter. Only lymphvascular space involvement (P &lt; 0.0001) was significantly correlated to pelvic lymph node metastasis. We suggest that all patients with endometrial cancer who are taken to the operating room for primary therapy should be prepared to undergo extended surgical staging, except when clinical or operative factors increase patients' morbidity.
