Evaluation of ovarian cancer remission markers HE4, MMP7 and Mesothelin by comparison to the established marker CA125.

ABSTRACT: Evaluate and compare the effectiveness of CA125, HE4, Mesothelin and MMP7 marker levels to monitor ovarian cancer patients after surgery and chemotherapy. Evaluate the lead time of a rise of marker levels before recurrence.The study consists of 23 patients with advanced stage ovarian/fallopian tube cancer. Blood was drawn after front line surgery and chemotherapy treatment and at 3 month intervals thereafter. One patient had chemoresistant disease, two patients remained in remission and 20 patients had recurring disease and were used for marker evaluation.In five patients HE4 was the only marker to elevate before recurrence with a lead time of up to 4½ months including one patient who did not have a CA125 response at all. In a further two patients, HE4 increased before CA125 did. In four of these seven patients, HE4 levels were consistently at or above threshold during remission when both CA125 and imaging results were negative. MMP7 elevated before recurrence in one patient who was negative for the other markers. Mesothelin elevated in two patients who were also positive for CA125 and HE4.HE4 can predict ovarian cancer recurrence earlier than CA125 and it can be elevated in patients that do not express CA125 at sufficient levels to make a clinical decision. MMP7 and Mesothelin have lower potential as markers for ovarian cancer recurrence to complement CA125. A failure of HE4 levels to normalize at completion of standard therapy may indicate a poor prognosis.

Project description:Risk of Ovarian Malignancy Algorithm (ROMA) combing human epididymis secretary protein 4 (HE4) and CA125 showed better diagnostic accuracy for epithelial ovarian cancer (EOC) when compared with HE4 or CA125 alone; however, other studies showed no or worse diagnostic accuracy. We aim to conduct a prospective and multicenter clinical trial to compare the diagnostic accuracy of HE4, CA125, and ROMA for EOC.A prospective and multicenter (n = 9) trial including 2481 individuals was performed in Chinese women. HE4, CA125, and ROMA diagnostic accuracy were evaluated according to different menopausal status and stages of EOC. Their diagnostic values were evaluated by the area under curve (AUC) and compared by the Z scores. Diagnostic specificity of other kinds of participants (n = 1098) was also evaluated.For discriminating between healthy control (HC) and EOC, only CA125 showed significant difference for discriminating HC and EOC in all the individuals when compared with HE4 and ROMA (P < 0.001 and P = 0.02, respectively), at the cutoff value of 31.5, the sensitivity (SN) and specificity (SP) were 88.6% and 97.1%. For discriminating between benign pelvic mass (BPM) and EOC, ROMA showed significant difference for discriminating BPM and EOC in the all individuals (P = 0.01 and P = 0.02, respectively) and the postmenopausal individuals (P = 0.03 and P = 0.04, respectively), at the cutoff value of 27.3 and 34.5, the SNs were 97.0% and 89.4%, SPs were 81.4% and 82.5%, separately. Within all kinds of diseases, there was no significant difference in specificity between CA125 and HE4.In conclusions, when HE4, CA125, and ROMA were compared with each other according to different menopausal status, and stages. Only CA125 showed significant difference for discriminating HC and EOC in all the individuals, and ROMA for discriminating BPM and EOC in the all individuals and postmenopausal individuals when compared with HE4 or CA125. HE4 has showed no significant difference in specificity with all kinds of diseases when compared with CA125.

Project description:ObjectiveSurvival in epithelial ovarian cancer (EOC) remains poor. Most patients are diagnosed in late stages. Early diagnosis increases the chance of survival. We used the proximity extension assay from Olink Proteomics to search for new protein biomarkers with the potential to improve the diagnostic performance of CA125 and HE4 in patients with ovarian tumors.Material and methodsPlasma samples were obtained from 180 women with ovarian tumors; 30 cases of benign tumor, 28 cases with borderline tumors, 25 early EOC cases (FIGO stage I) and 97 advanced EOC cases (FIGO stages II-IV). Proteins were measured using the Olink® Oncology II and Inflammation panels. For statistical analyses, patients were categorized into benign tumors versus cancer and benign tumors versus borderline + cancer, respectively.ResultsWe analyzed 177 biomarkers. Thirty-four proteins had ROC AUC > 0.7 for discrimination between benign tumors and cancer. Fifteen proteins had ROC AUC > 0.7 for discrimination between benign tumors and borderline tumors + cancer. HE4 ranked highest for both comparisons. A reference model with HE4, CA125 and age (AUC 0.838 for benign tumors vs. cancer and AUC 0.770 for benign tumors vs. borderline tumors + cancer) was compared to the reference model with the addition of each of the remaining proteins with AUC > 0.7. ITGAV was the only individual biomarker found to improve diagnostic performance of the reference model, to AUC 0.874 for benign tumors vs. cancer and AUC 0.818 for benign tumors vs. borderline tumors + cancer (p < 0.05). Cross-validation and LASSO regression was combined to select multiple biomarker combinations. The best performing model for discrimination between benign tumors and borderline tumors + cancer was a 6-biomarker combination (HE4, CA125, ITGAV, CXCL1, CEACAM1, IL-10RB) and age (AUC 0.868, sensitivity 0.86 and specificity 0.82, p = 0.016 for comparison with the reference model).ConclusionHE4 was the best performing individual biomarker for discrimination between benign ovarian tumors and EOC including borderline tumors. The addition of other carcinogenesis-related biomarkers in a multiplex biomarker panel can improve the diagnostic performance of the established biomarkers HE4 and CA125.
