Abstract
Gastric cancer (GC) is the fifth most common cancer worldwide and the second leading cause of cancer-related death. GC is usually diagnosed at an advanced stage due to late presentation of symptoms. Therefore, there is a need for establishing more sensitive and specific markers useful in early detection of the disease when a cancer is asymptomatic to improve the diagnostic and clinical decision-making process. Some researchers suggest that chemokines and their specific receptors play an important role in GC initiation and progression via promotion of angiogenesis, tumor transformation, invasion, survival and metastasis as well as protection from host response and inter-cell communication. Chemokines are small proteins produced by various cells such as endothelial cells, fibroblasts, leukocytes, and epithelial and tumor cells. According to our knowledge, the significance of chemokines and their specific receptors in diagnosing GC and evaluating its progression has not been fully elucidated. The present article offers a review of current knowledge on general characteristics of chemokines, specific receptors and their role in GC pathogenesis as well as their potential usefulness as novel biomarkers for GC.

Abstract
Background Gastric cancer (GC) is characterized by aggressive behavior and a high mortality rate. The diagnosis of GC is challenging because the GC is often diagnosed in an advanced stage. The use of tumor markers is a putative way to improve the detection and treatment in patients with GC. Summary In this article, we review the significance of serum carbohydrate antigen (CA) 19-9, carcinoembryonic antigen (CEA), and CA 72-4 in GC. The results from different studies regarding the diagnostic and prognostic role of CA 19-9, CEA, and CA 72-4 in GC are encouraging, but inadequate sensitivity and specificity obstruct their use as standardized and unconditionally reliable markers in GC. New prospective clinical trials are mandatory for clarifying their value in GC. Key Message CA 19-9, CEA, and CA 72-4 should not be used for screening and early diagnosis in GC, whereas they are beneficial in the detection of late GC. CA 19-9, CEA, and CA 72-4 could be used as prognostic and monitoring tools in GC, and their combined measurement in shorter periods of time is the best method to increase sensitivity and specificity. Practical Implications Serum CA 19-9, CEA, and CA 72-4 are useful diagnostic and prognostic tumor markers in GC.

Abstract
In a prospective study we evaluated in 48 patients with primary ovarian carcinoma the prognostic value of the preoperative circulating serum levels of CA 125 and TAG-72. Serum levels of CA 125 were above the cutoff level of 35 U/ml in 68% of patients, TAG-72 levels were higher than 6 U/ml in 50% of patients, while the simultaneous use of the two markers increased the sensitivity to 75%. Pretreatment CA 125 and TAG-72 levels were significantly lower (p < 0.05, for both) in patients with well differentiated tumors than in those with moderate or poor differentiation. Similarly, both marker levels were significantly higher (p < 0.001) in patients with residual disease after cytoreductive surgery than in those with no residual tumor. In addition, the CA 125 levels were also higher in initial stages (I-II) than in more advanced stages (III-IV) (p < 0.05), whereas TAG-72 levels were higher (p < 0.05) in patients with mucinous or endometrioid tumors than in those with serous carcinomas. The results further indicated that high preoperative serum levels of CA 125 and TAG-72 were associated with a shorter overall survival (p < 0.001 and p < 0.01, respectively). Finally, separate Cox multivariate analysis showed that preoperative CA 125 and TAG-72 serum levels were, after stage, the strongest factors to predict overall survival (p < 0.0001, p < 0.05 and p < 0.005, respectively) in patients with ovarian carcinoma.

Abstract
We evaluated in 74 patients with resectable primary gastric carcinoma, the prognostic value of the preoperative circulating serum levels of CEA and TAG-72. Serum levels of CEA were above the cutoff level of 6 ng/ml in 18.9% of patients; TAG-72 levels were higher than 6 U/ml in 31% of patients. Pretreatment mean CEA levels were significantly lower (p<0.01) in patients with stage I tumors (2.9 ± 0.3 ng/ml) than in those with more advanced tumors (stage II: 14.5 ± 6.8 ng/ml; stage HI-TV: 6.8 ± 1.5 ng/ml). Similarly, significant differences in mean TAG-72 serum levels were found between stage I (3.5 ± 1.8 U/ml) and stage II and stage III-IV (30.4 ± 20.7 U/ml and 26.1 ± 9.7 U/ml, respectively) (p<0.05). In addition, TAG-72 levels were also higher in poorly differentiated and moderately differentiated tumors (38.5 ± 20.1 U/ml and 23.1 ± 9.4 U/ml, respectively) than in well differentiated tumors (4.4 ± 0.9 U/ml) (p<0.05). The results further indicated that high preoperative serum levels of CEA predicted shorter relapse-free survival duration (p<0.01), and that high TAG-72 levels were associated with shorter relapse-free and overall survival (p < 0.0001 and p < 0.0005, respectively). In addition, separate Cox multivariate analysis showed that preoperative TAG-72 was, after stage, the strongest factor to predict both relapse-free and overall survival (p < 0.0001 and p < 0.005, respectively) in patients with gastric cancer.

Abstract
The specificity of the tumor markers used to date in patients with gastric cancer has not been satisfactory. For this reason we decided to evaluate the utility of TAG-72 in this disease. Between 1993 and 1998 we determined the levels of TAG-72 in 638 subjects (148 healthy volunteers, 33 patients with chronic renal failure (CRF), 149 patients with benign diseases of the liver, 95 patients with benign gastrointestinal diseases and 213 patients with gastric cancer). TAG-72 was measured using an IRMA method. Statistical analysis of the data was performed with the BMDP package. We established a cutoff for TAG-72 of 3 U/mL, corresponding to the 92.6th percentile of the healthy controls. We observed that neither CRF nor benign liver diseases affected TAG-72 levels, while certain benign gastrointestinal diseases did cause alterations of the marker. Using Cox multivariate analysis we discovered that the preoperative TAG-72 level was an independent prognostic variable associated with both disease-free and overall survival. We conclude that, although TAG-72 is not useful for the diagnosis of gastric cancer, it is a suitable tool for disease monitoring and prognostic assessment.

Abstract
Aim To investigate the relationship between the serum levels of CEA, CA19-9, CA24-2, CA72-4, and AFP in patients with gastric cancer (GC) and their clinicopathological characteristics; to analyze the efficacy of these tumor markers in evaluating the prognosis of GC. Methods Overall, 389 patients with GC either located in the gastric cardia (132), the pyloric antrum (112) or the body of the stomach (145) were included in the study. Serum levels of CEA, CA19-9, CA72-4, and AFP were detected with the ECLIA method, while CA24-2 was measured with ELISA. Results First, the serum level of CEA in GC patients with a cardia-located cancer was significantly higher than in patients with pyloric antrum-located cancer (p=0.050). CA72-4 level in patients with GC located in the gastric body was significantly higher than in patients with cardia and pyloric antrum-located cancers (p=0.042 and p=0.039, respectively). Secondly, serum CA19-9 and CA24-2 levels in females with cardia-located GC were significantly higher than those in males with the same type of tumor (p=0.037 and p=0.033, respectively). Additionally, for females with gastric body-located GC the levels of CEA and CA72-4 were significantly higher than those in male patients with the same type of tumor (p=0.047 and p=0.048, respectively). Conversely, in female GC patients with pyloric antrum-located cancer the serum levels of CA19-9 and CA24-2 were significantly lower than those in male patients with the same type of cancer (p=0.013 and p=0.007, respectively). Moreover, CEA, CA19-9, CA24-2, and CA72-4 levels were strongly related to TNM grade and histological anatomy stage, whereas CEA and CA72-4 levels were strongly related to lymph node stage (p=0.000 and p=0.042, respectively). Patients with vascular embolism had higher serum levels of CEA, CA19-9, CA24-2, and CA72-4 compared with patients without vascular embolism (p=0.005, p=0.031, p=0.007, and p=0.014, respectively). In patients with distant metastases and ascites the levels of CEA, CA19-9, and CA24-2 were higher than in patients without these conditions (p=0.003, p=0.001, p=0.001, p=0.016, p= 0.011, and p=0.030, respectively). Serum CEA, CA19-9, and CA24-2 levels showed correlations with tumor invasive depth and growth types (p=0.001, p=0.040, and p=0.035, respectively). Patients with lump and catheter tumor growth types had significantly higher AFP levels than patients with invasion and anabrosis growth types (p=0.034 and p=0.005, respectively). Tumor size was correlated with the preoperative serum levels of CEA, AFP, and CA72-4 (p=0.007, p=0.020, and p=0.008, respectively). Additionally multiple linear regression analysis showed that preoperative levels of CEA and CA72-4 were correlated to TNM stages, CA19-9 and CA24-2 levels were correlated to both gender and distant metastasis, and AFP was correlated only to ascites. During follow-up there were 115 deaths. Median survival time for GC patients with negative preoperative CEA was 18.07 months, and was 10.97 months for patients with preoperative CEA positive levels (p=0.0005). Similarly, the median survival time for GC patients with negative preoperative CA72-4 was 33.60, and was 16.03 months for patients with preoperative CA72-4 positive levels (p=0.0041). Conclusions The preoperative levels of CEA, CA19-9, CA24-2, CA72-4, and AFP were closely related to TNM grade, gender, distant metastasis and ascites. These makers seem to play important roles in predicting recurrence and metastasis, and in evaluating prognosis.

Abstract
The objective of this study is to quantitatively analyze the predictive strength among the conventional serological tumor biomarkers for gastric cancer in Chinese population. Thirty-three hospital-based case-control studies were searched out through Chinese databases and PubMed during 1999-2009. Gastric cancer cases and healthy volunteers or benign gastric diseases controls were detected of any of serological CA724, CA242, CEA, CA199, CA125, or CA153. Areas under the curve (AUC) and optimal Q indexes of summary receiver operating characteristics (sROC) curves were quantitatively compared. The summary positive and negative likelihood ratios (sLR + and sLR-) were pooled. Totally, 2,390 gastric cancer cases and 2,893 controls were analyzed. CA724 and CA242 both had the greatest AUCs (0.88), respectively, followed by the combination CA724 + CEA + CA199 (0.85), CA125 (0.82), CEA (0.80), and CA199 (0.76), but all of them had no statistical significance to CA153 (negative control) by Z tests, possibly due to relatively great standard errors. The results of Q index analyses were similar to those of AUCs, that CA724 and CA242 had the optimal strength. The sLR + of CA724 (16.08, 95 % confidence interval (CI) 7.86-32.86) or CA242 (11.03, 95 % CI 7.12-17.08) was strong to judge the gastric cancer status based on its positive result. The combination of CA724 + CEA + CA199 had the prior sLR- (0.33, 95 % CI 0.25-0.43) to the others. Serological CA724 or CA242 has predictive effect for screening gastric cancer and can be recommended into the screening program of population-based or symptomatic cases. However, prospective epidemiological studies are required before confirmative conclusion.

Abstract
Objective: Data from prospective studies indicate a positive impact of gastric cancer screening programs on mortality associated with the disease. Unfortunately, endoscopic procedures, widely regarded as uncomfortable, face low patient compliance, thus underscoring the need for reliable biological markers capable of detection of tumor growth in bodily fluids. Furthermore, in light of the emerging patient-friendly, still devoid of histopathological capabilities, capsule endoscopy, gastric fluid may prove valuable for biomarker-assisted cancer diagnosis. We set out to determine whether CA72-4 measurement in gastric fluid may be of benefit for detection of gastric cancer.Design: Open prospective study.Setting: Sample collection was performed at a tertiary referral center for patients with gastroenterological diseases; immunological analysis was performed at the R&D facility of a commercial biotechnology company. Studies were part of an EU-FP6 project (NEMO).Patients: 176 patients referred for endoscopy due to gastrointestinal complaints.Interventions: Gastric juice was aspirated endoscopically according to standard operating procedures, volume and pH were measured immediately and samples stored at -80°C.Outcome measures: Concentration of CA72-4 tumor marker was evaluated by enzyme-linked immunosorbent assay (ELISA).Results: Median CA72-4 levels were about 4-fold higher in cancer patients compared with patients with normal gastric findings, gastric inflammation, intestinal metaplasia or other diseases (p=0.001). Multivariate linear regression analysis revealed that elevated CA72-4 was significantly predicted by gastric carcinoma adjusted for H. pylori status, age, smoking status, PPI dose, and pH of aspirate (R2=0.27, p<0.0001). In this model, diagnosis of gastric carcinoma had by far the greatest influence. At a cut-off level of 100 U/ml, CA72-4 had 75% sensitivity and 89% specificity for detection of gastric cancer.Conclusions: Based on our findings, CA72-4 level assessment in gastric fluid, featuring yet unmatched accuracy of malignant neoplasia detection may prove beneficial for gastric cancer screening.

Abstract
AIM The aim of the present observational study was to evaluate the diagnostic accuracy of CEA, CA 19-9 and CA 72-4 in patients with bowel obstruction. METHODS One-hundred three patients admitted to an emergency unit with clinical and radiological signs of intestinal occlusion of unknown origin were prospectively studied. Patients submitted to emergency surgery were excluded. All patients underwent standard diagnostic procedures and serological assay of tumor markers. RESULTS Colorectal cancer was diagnosed in 22 patients (21.4%), while 81 patients (78.6%) presented a benign condition. The sensitivity of CEA, CA 19-9 and CA 72-4 for colorectal cancer was 36.4%, 31.8% and 9.1%, respectively. Marker specificity was 91.4%, 90.1% and 95.1%, respectively. The combination of CEA and CA 19-9 increased the sensitivity to 45.5% but decreased the specificity to 83.9%. The overall accuracy was 79.6%, 77.7% and 76.7%, respectively. All positive cancer cases had advanced disease. All patients with CEA levels >10 ng/mL or CA 19-9 >100 U/mL had colorectal cancer. CONCLUSIONS Even in a highly selected population, tumor marker sensitivity was rather low and specificity incomplete. However, elevated levels may guide the diagnostic and therapeutic course in patients with obstructing colorectal cancer.

Abstract
BACKGROUND Updated National Academy of Clinical Biochemistry Laboratory Medicine Practice Guidelines for the use of tumor markers in the clinic have been developed. METHODS Published reports relevant to use of tumor markers for 4 cancer sites--liver, bladder, cervical, and gastric--were critically reviewed. RESULTS Alpha-fetoprotein (AFP) may be used in conjunction with abdominal ultrasound for early detection of hepatocellular carcinoma (HCC) in patients with chronic hepatitis or cirrhosis associated with hepatitis B or C virus infection. AFP concentrations >200 microg/L in cirrhotic patients with typical hypervascular lesions >2 cm in size are consistent with HCC. After a diagnosis of HCC, posttreatment monitoring with AFP is recommended as an adjunct to imaging, especially in the absence of measurable disease. Although several urine markers have been proposed for bladder cancer, none at present can replace routine cystoscopy and cytology in the management of patients with this malignancy. Some may, however, be used as complementary adjuncts to direct more effective use of clinical procedures. Although carcinoembryonic antigen and CA 19-9 have been proposed for use gastric cancer and squamous cell carcinoma antigen for use in cervical cancer, none of these markers can currently be recommended for routine clinical use. CONCLUSIONS Implementation of these recommendations should encourage optimal use of tumor markers for patients with liver, bladder, cervical, or gastric cancers.

Abstract
BACKGROUND Early peritoneal recurrence of gastric carcinoma following curative resection remains a great challenge in the treatment and prevention of this disease. AIM To analyze the relationship between levels of tumor markers, carcinoembryonic antigen (CEA) and CA 19-9 in the sera and peritoneal washing, and anatomopathological aspects of the gastric carcinoma. METHODS Of the 46 patients in the study, 29 (63.0%) were males and 17 (37.0%) females. Mean age was 63.6 +/- 11.7 years (31 to 91 years). Peripheral venous blood samples were collected from the upper limb vein from both patient groups after anesthetic induction, in order to determine serum levels of CEA and CA 19-9. After the end of the procedure, 50 mL of physiologic solution was introduced into the bottom of the Douglas sack and a portion aspirated to determine CEA and CA 19-9 levels in the peritoneal washing. Levels of CEA and CA 19-9 in the sera and peritoneal washing were compared to the following variables: lesion diameter < or = 4 cm or > 4 cm, lymph node involvement, angiolymphatic invasion, depth of invasion into gastric wall, and initial or late stage. RESULTS Sera CEA levels were significantly higher in patients with lesions >5 cm. CEA levels in the sera and peritoneal washing were significantly greater in patients with signet ring cell gastric carcinoma. In addition, levels of CEA in peripheral blood and peritoneal washing showed significant association with the degree of carcinoma penetration into the gastric wall, while sera CEA was significantly higher in patients at more advanced stages. There was no significant difference between sera and peritoneal CEA values regarding grade of differentiation. Patients with gastric lesions measuring > 5 cm and more differentiated lesions had significantly higher sera CA 19-9 values. In patients with lymph nodes invasion by gastric carcinoma, CA 19-9 levels in peritoneal washing were significantly higher than in peripheral blood. Levels of CA 19-9 in peritoneal washing were significantly greater at advanced stages than the initial stage of the gastric carcinoma. CONCLUSIONS Elevated levels of CA 19-9 in peritoneal washing were significantly associated with more advance stages of gastric carcinoma and was more reliable predictive factor for staging than sera CA 19-9 levels. CEA levels in the sera more accurately reflected neoplasia stage than levels in peritoneal washing.

Abstract
BACKGROUND: Determining levels of tumor markers in peritoneal washing enables likelihood of peritoneal recurrence to be ascertained in patients with high marker levels, thereby allowing provision of more accurate adjuvant treatment and postoperative follow up. AIM: To analyze the relationship between levels of tumor marker CA72-4 in serum and peritoneal washing, and morphological aspects of gastric carcinoma. METHOD: This study analyzed 32 consecutively-operated patients with gastric carcinoma, who underwent subtotal, total or palliative gastrectomy. The variables studied were CA72-4 levels in serum and peritoneal washing, lesion site, stage, degree of cell differentiation, operation performed, and number of extirpated and involvement lymph nodes. Of the 32 patient sample, 21 (65.6%) were male and 11 (34.4%) female. Mean age was 62.6 ± 14.2 years (29 to 91 years). Following anesthetic induction, peripherical venous blood was collected through percutaneous punction of an upper limb vein. After the procedure, 50 mL of physiologic solution at 37ºC was introduced into the cul-de-sac. A 10 mL volume of this liquid was aspirated from the cavity and the peritoneal washing tested for CA72-4 levels. Normal values for CA72-4 levels in serum were considered <7 U/mL and high levels as >7U/mL, whilst for the peritoneal washing normal levels were <0.61 U/mL, and abnormal >0.61 U/mL. RESULTS: Mean pre-operative serum levels for CA72-4 were 6.55 U/mL ± 15.30 (0.3 to 75.30 U/mL) whilst the mean level of CA72-4 in peritoneal washing was 8.50 U/mL ± 26.72 (0.3 to 142.00 U/mL); correlation between these levels was significant. Lymph nodes involvement by the gastric carcinoma correlated significantly with higher CA72-4 levels in both serum and peritoneal wash. There was no statistically significant correlation between serum level of CA72-4 and invasion into serosa by the gastric carcinoma. There was however, significant correlation between peritoneal washing levels of CA72-4 and involvement of serosa by gastric carcinoma. There was also a significant correlation between more advanced stages of gastric carcinoma and higher levels of CA72-4 in the peritoneal washing, although serum levels of CA72-4 and more advanced stage of gastric neoplasia showed no significant correlation. Degrees of cellular differentiation in the gastric carcinoma did not differ significantly with CA72-4 levels in serum or peritoneal washing. CONCLUSION: High levels of CA72-4 in peritoneal washing correlated significantly with lymph node metastasis and serosa involvement by the neoplasia, and also with more advanced stage of gastric carcinoma. The levels of CA72-4 in the blood correlated significantly with lymph node involvement by the gastric carcinoma, but not with serosa invasion or more advanced stage of neoplasia.

Abstract
The basis of a bacterial pathogenic process consists in the change of a certain host structure to a completely different one. This is accomplished by binding of a bacterial protein product to the host structure. Streptococcal NAD+-nucleosidase was explored as to its binding to the host receptor represented by beef heart extract. The bacterial product was found to bind to the host structure until the available host structure was fully saturated. The similarity of the above flows of macromolecules with some models of morphogenesis indicates the existence of diseases associated with the flow of a protein to the undesirable site in the organism. In such a case therapy with low-molar-mass substances is wrong in principle.

Abstract
BACKGROUND The aim of this study was to evaluate the risk of liver metastases after radical surgical treatment for gastric cancer, the potential risk factors involved, and the sensitivity of serum tumor markers during followup. STUDY DESIGN A total of 208 patients who had undergone curative resection for primary gastric cancer and a prospective followup protocol were studied. The association between clinicopathologic variables and hepatic recurrence was investigated using standard univariate methods and multivariate Cox regression analysis. RESULTS Mean followup time (+/- SD) for the entire patient population was 51 +/- 38 months (median 52 months) and was 88 +/- 24 months (median 81 months) for disease-free patients. Recurrence of gastric cancer was documented in 109 of 208 patients (52.4%). Liver metastases were found in 28 of 208 patients (13.5%); in most of these patients (82.1%) diagnosis was made within 2 years after surgical treatment. The estimated cumulative risk of liver metastases after 5 years was 16.4%. Cox regression analysis identified lymph node involvement (adjusted relative risk [RR] = 6.28, 95% confidence interval [CI] = 2.11 to 18.70, p = 0.001), preoperative positivity for CEA, CA 19-9, or CA 72-4 (RR = 5.18, 95% CI = 1.75 to 15.37, p = 0.003), and intestinal histotype (RR = 3.08, 95% CI = 1.06 to 8.96, p = 0.039) as independent predictors of hepatic recurrence. In 27 of 28 cases hepatic recurrence was associated with an increase in CEA, CA 19-9, or CA 72-4 serum levels above the cutoff, either before or at the time of the clinical diagnosis (sensitivity 96.4%). CONCLUSIONS Preoperative positivity for serum tumor markers, lymph node involvement, and intestinal histotype are risk factors for liver metastases after radical surgical treatment for gastric cancer. Postoperative measurement of serum tumor markers may be useful for an early diagnosis of hepatic recurrence during followup.

Abstract
BACKGROUND The aim of this longitudinal study was to evaluate the effectiveness of the serum tumor markers CEA, CA 19-9, and CA 72-4 in the early diagnosis of recurrence of gastric cancer. METHODS One hundred and thirty-three patients who had undergone potentially curative surgery were considered. Serum samples were obtained preoperatively, 1 week after surgery, and at every follow-up examination. Mean follow-up time for the entire patient population was 41 +/- 33 months, and 71 +/- 27 months for patients classified as disease-free. RESULTS Preoperative positivity was 16% for CEA, 35% for CA 19-9, and 20% for CA 72-4. Recurrence of disease was found in 75 patients (56%). Marker sensitivity in recurrent cases was 44% for CEA, 56% for CA 19-9, and 51% for CA 72-4; the combined use of the three markers increased sensitivity to 87%, which reached 100% in patients with positive preoperative levels. Marker specificity, evaluated in 58 disease-free patients, was 79% for CEA, 74% for CA 19-9, and 97% for CA 72-4. CONCLUSIONS The combined assay of CEA, CA 19-9, and CA 72-4 may be useful for early diagnosis of recurrence of gastric cancer; however, only CA 72-4 positivity should be considered a specific predictor of tumor recurrence.

Abstract
Early gastric cancer recurrence is sometimes difficult to diagnose even by protocols using imaging techniques and tumor markers. We report a gastric cancer recurrence diagnosed by the appearance of a Sister Mary Joseph's nodule that illustrates the lack of sensitivity of these methods. We also discuss the protocol we currently follow for these patients.

Abstract
BACKGROUND To assess the differential diagnostic potential of physical examination, ultrasound, the serum CA 125 assay, and serum CA 72-4 assay, and the contribution of each parameter to a logistic model predicting the probability of malignancy in postmenopausal patients presenting with a pelvic mass. PATIENTS AND METHODS In a multicenter, prospective study a total of 155 patients were evaluated preoperatively using a standard protocol for pelvic examination, transvaginal (occasionally additional abdominal) ultrasound, and serum CA 72-4 (cutoff level 3 U/ml) and CA 125 (cutoff level 35 U/ml). RESULTS Fifty-nine malignant (39%) and 92 benign (61%) pelvic tumors were found in addition to 4 borderline tumors (3%). Forty-three patients appeared to have ovarian carcinoma, FIGO Stage III or IV in 28 cases. Borderline tumors were excluded from the statistical calculations. The diagnostic accuracy of each single parameter, i.e., pelvic examination, ultrasound, and serum CA 125 and CA 72-4 in discriminating between benign and malignant pelvic masses gave highly similar results (81, 76, 78, and 81% respectively). Best sensitivity was found in pelvic examination (92%); best specificity was found in CA 72-4 (93%). Using logistic regression analysis the power of pelvic examination appeared to be the most relevant (adjusted odds ratio 12.1), followed by ultrasound (odds ratio 9.7), serum CA 125 (odds ratio 5.0), and serum CA 72-4 (odds ratio 4.9). Age appeared to be nonpredictive. The logistic model gives a correct prediction in 87% of all cases. CONCLUSIONS The addition of serum CA 72-4 to the combination of pelvic examination, ultrasound, and serum CA 125 leads to an improved discrimination between malignant and benign pelvic masses.
