The importance of the Peritoneal Cancer Index (PCI) to predict surgical outcome after neoadjuvant chemotherapy in advanced ovarian cancer. Arch Gynecol Obstet 2022; 306:1665-1672. [PMID: 35357582 PMCID: PMC9519707 DOI: 10.1007/s00404-022-06527-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 03/11/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE Achieving complete cytoreduction (CCR) is crucial for a patient's prognosis with advanced epithelial ovarian cancer (EOC). So far, prognostic predictors have failed to predict surgical outcome after neoadjuvant chemotherapy (NACT). In clinical trials, scores were used to predict operability in recurrent ovarian cancer (Harter et al. in N Engl J Med 385(23):2123-2131, 2021) but there is no known prediction score for CCR after NACT. The Peritoneal Cancer Index (PCI) is an established tool to predict surgical outcome in primary setting (Lampe et al. in 25:135-144, 2015). We now examined the predictive power of the PCI to achieve CCR after NACT. METHODS In this single-center study, the data of patients with advanced stage EOC (FIGO > IIIb) treated between 01/2015 and 12/2020 were analyzed retrospectively. Inclusion criteria were a mandatory staging laparoscopy, a PCI score > 25, and NACT. CT scans were analyzed in blinded fashion according to RECIST criteria (Borgani et al. in 237; 93-99, 2019) Reaction of PCI after NACT was compared with the analysis of radiologic imaging and CA-125 levels. RESULTS Three hundred and sixteen patients were screened, 62 were treated with NACT, and 23 were included in our analysis. 87% of cases presented with an FIGO IIIc stadium. The reduction of PCI itself after NACT showed to be the most powerful predictor for achieving CCR. The reduction of the initial PCI score by minimum of 8.5 points was a better predictor for CCR than reaching a PCI < 25. In contrast to data deriving from patients undergoing primary debulking surgery (PDS), we found a PCI of 17, rather than 25, to be a more valuable cut-off for CCR in neoadjuvant-treated patients. CONCLUSION The extend of PCI reduction after NACT is a better predictor for achieving CCR compared with CA125 levels and radiologic imaging. The PCI must be assessed differently in neoadjuvant setting than in a primary situation. CCR was most likely for a post-NACT PCI < 17.

The added value of CA125 normalization before interval debulking surgery to the chemotherapy response score for the prognostication of ovarian cancer patients receiving neoadjuvant chemotherapy for advanced disease. J Cancer 2021; 12:946-953. [PMID: 33403051 PMCID: PMC7778530 DOI: 10.7150/jca.52711] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Accepted: 11/15/2020] [Indexed: 11/11/2022] Open
Abstract
Objective: To investigate whether CA125 normalization following neoadjuvant chemotherapy (NACT) can complement the chemotherapy response system (CRS) in the prognostication of patients with tubo-ovarian high-grade serous carcinoma (HGSC). Methods: In total, 118 HGSC patients who received NACT followed by interval debulking surgery (IDS) for FIGO stage IIIC-IV disease were included, and their clinical data were retrospectively reviewed. The primary endpoint was progression-free survival (PFS). Cox regression analysis was performed to identify predictors of PFS. Results: Following NACT, CRS3 was noted in 35 patients (29.7%), and CA125 normalization (≤ 35 U/ml) was noted in 54 patients (45.8%). Both CRS3 and CA125 normalization were identified as independent prognosticators of PFS. Combining these two factors, we stratified the 106 patients into three groups with different risks of recurrence: low-risk group (CRS3 + post-NACT CA125≤ 35 U/ml; n = 17, 14.4%), intermediate-risk group (CRS3 + post-NACT CA125 > 35 U/ml; n = 19, 16.1%) and high-risk group (CRS1-2; n= 82, 69.5%). The differences in PFS between the three groups were significant (log-rank test, P < 0.0001). In Cox regression analyses, the new stratification method was found to have an independent prognostic effect. Conclusion: Both the CRS system and the normalization of CA125 following NACT could reliably predict the risk of recurrence following primary treatment. The combination of the two factors refined the prognostic stratification of HGSC patients who were treated with NACT and IDS.

Abstract
Aim: The aim of the study is to evaluate percent fall in CA-125 levels after neoadjuvant chemotherapy (NAC) and preoperative CA-125 value to predict surgical and survival outcomes in women with advanced-stage epithelial ovarian cancer (EOC). Methods: A retrospective review of 406 women receiving NAC for advanced-stage EOC from January 2012 to July 2015 was conducted. Data were collected for demography, radiographic profile, CA-125 levels before and after NAC, chemotherapy, and surgicopathological information. Percent fall in CA-125 was categorized into two groups: <95% (R < 95) and >95% (R > 95) fall from prechemotherapy to preoperative levels. Similarly, women were also categorized using preoperative CA-125 levels of <100 and >100 U/ml. A subset of women from January 2012 to December 2013 was followed to June 2015 for evidence of any recurrence to determine survival outcomes. Results: About 56% women had R > 95 and 44% had R < 95. As compared to R < 95, R > 95 group was more likely to have complete cytoreduction (P = 0.00). Furthermore, women with R > 95 had significant better progression-free survival (PFS) as compared to women with R < 95 (P = 0.009) but no difference in overall survival (OS) (P = 0.28). Women with preoperative CA-125 <100 had significant higher number of complete cytoreduction (55% vs. 40%; P = 0.00) and were associated with both PFS (P = 0.007) and OS benefit (P = 0.02). Conclusion: Our data showed that >95% fall in CA-125 and an absolute preoperative CA-125 value of <100 U/ml is associated with better surgical and survival outcome in women with advanced EOC. These data are important in patient counseling and treatment planning.

Identification of Ovarian Cancer Patients Most Likely to Achieve Chemotherapy Response Score 3 Following Neoadjuvant Chemotherapy: Development of a Predictive Nomogram. Front Oncol 2020; 10:560888. [PMID: 33123471 PMCID: PMC7571668 DOI: 10.3389/fonc.2020.560888] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Accepted: 08/31/2020] [Indexed: 12/27/2022] Open
Abstract
Background: The chemotherapy response score (CRS) system is a reproducible prognostic tool for patients receiving neoadjuvant chemotherapy (NACT) for tubo-ovarian high-grade serous carcinoma (HGSC). Achieving CRS 3 following NACT can be used as a surrogate for progression-free survival (PFS) and overall survival (OS). This study aimed to identify predictors of CRS 3 and develop a predictive nomogram. Methods: Data were extracted from 106 HGSC patients receiving NACT. Logistic regression was used to identify independent predictors for CRS 3. A nomogram was established based on the multivariate regression model. Results: All patients received three cycles of NACT, and CRS 3 was observed in 24 (22.6%) patients. Compared with patients in the CRS 1–2 group, patients in the CRS 3 groups had significantly improved PFS (log-rank test P < 0.0001). The multivariate regression analysis identified post-NACT CA125, percent decrease in CA125, post-NACT human epididymis protein 4 (HE4), and post-NACT hemoglobin level as independent predictors of CRS 3. The Hosmer-Lemeshow test showed goodness-of-fit of this regression model (P = 0.272). The nomogram including these factors presented good discrimination (area under the curve = 0.82), good calibration (mean absolute error = 0.039), and a net benefit within the threshold probabilities of CRS 3 > 5%. Conclusions: We validated the prognostic role of the CRS system and developed a nomogram that predicts the possibility of CRS 3 following NACT. The nomogram helps to identify patients who would benefit the most from NACT. More studies are warranted to validate this model.

Abstract
Introduction: Due to the relatively low mutation rate and high frequency of copy number variation, finding actionable genetic drivers of high-grade serous carcinoma (HGSC) is a challenging task. Furthermore, emerging studies show that genetic alterations are frequently poorly represented at the protein level adding a layer of complexity. With improvements in large-scale proteomic technologies, proteomics studies have the potential to provide robust analysis of the pathways driving high HGSC behavior. Areas covered: This review summarizes recent large-scale proteomics findings across adequately sized ovarian cancer sample sets. Key words combined with 'ovarian cancer' including 'proteomics', 'proteogenomic', 'reverse-phase protein array', 'mass spectrometry', and 'adaptive response', were used to search PubMed. Expert opinion: Proteomics analysis of HGSC as well as their adaptive responses to therapy can uncover new therapeutic liabilities, which can reduce the emergence of drug resistance and potentially improve patient outcomes. There is a pressing need to better understand how the genomic and epigenomic heterogeneity intrinsic to ovarian cancer is reflected at the protein level and how this information could be used to improve patient outcomes.

Abstract
Objectives For patients with advanced ovarian cancer, neoadjuvant chemotherapy (NACT) can significantly increase the rate of optimal cytoreduction. However, this does not translate into a survival benefit. The aim of this study was to investigate the feasibility and effect of neoadjuvant laparoscopic hyperthermic intraperitoneal chemotherapy (NLHIPEC). Methods Between March 2016 and February 2018, 14 patients with advanced ovarian cancer who were not candidates for optimal cytoreduction via primary debulking surgery (PDS) received NLHIPEC. Their clinical data were retrospectively analyzed. Results No patients experienced intraoperative complications during NLHIPEC. Grade 3 adverse events (AEs) were noted in two (14.3%) patients, and all patients received planned NACT without dose delay or dose reduction. Following NACT, CA125 levels <35 U/mL and <20 U/mL were observed in six (42.9%) patients and five (35.7%) patients, respectively. All patients underwent interval debulking surgery (IDS) after the last NACT cycle. After IDS, R0 resection was achieved in 10 (71.4%) patients without intraoperative injury, and one (7.1%) patient developed a grade 3 AE. During a median follow-up time of 16 months, no patients died of disease, and the median progression-free survival (PFS) was not achieved. Progression was noted in six (42.9%) patients (range, 9–21 months). Conclusions NLHIPEC appears to be a feasible option for ovarian cancer patients who have a low likelihood of achieving optimal cytoreduction during PDS.

Abstract
Various kinetic parameters of serum CA-125 have been reported to have better correlation with outcomes for patients treated with neoadjuvant chemotherapy (NAC). This study aimed to compare the available kinetic parameters of serum CA-125 in an external cohort of advanced-stage ovarian cancer. Using the cancer registry databases from the Yonsei Cancer Hospital, we retrospectively reviewed 210 patients with advanced-stage ovarian cancer, treated with NAC followed by interval debulking surgery. We compared area under the receiver-operating characteristics curves (AUCs), false negative rate, and negative predictive value (NPV) using 10 different models for optimal cytoreduction and platinum resistance. In addition, we compared incremental AUC for progression-free survival (PFS) and overall survival (OS). No gross residual tumor was observed in 37.0% and residual tumors <1 cm in 82.2% of patients. No model using CA-125 kinetic parameters had an AUC higher than >0.6 for predicting optimal cytoreduction. After adjusting for age, BMI, disease stage, and histologic subtypes, all models had an AUC >0.70 for predicting platinum resistance. However, no model had a high enough NPV (highest value = 82.0%) to avoid chemotherapy futility. For survival outcomes, no model had an incremental AUC >0.70 for predicting either PFS or OS. None of the proposed serum CA-125 kinetic parameters showed high accuracy in predicting optimal cytoreduction, platinum resistance, or survival in patients receiving NAC. For advanced-stage ovarian cancer treated with NAC, there is a need to discover reliable biomarkers to better stratify patient response groups for optimal treatment decision-making.

Abstract
PURPOSE To determine the most powerful cancer antigen 125 (CA125)-related prognostic factor for advanced epithelial ovarian cancer (EOC) and to identify cut-off values that distinguish patients with a poor prognosis from those with a good prognosis. MATERIALS AND METHODS We included 223 patients who received staging laparotomy and were diagnosed with stage IIC-IV serous EOC. Cox regression analysis was used to determine the most significant prognostic factor among the following variables: serum CA125 before surgery and after the first, second, and sixth cycles of chemotherapy; the nadir CA125 value; the relative percentage change in CA125 levels after the first and second cycles of chemotherapy compared to baseline CA125; CA125 half-life; time to nadir; and time to normalization of the CA125 level. RESULTS The CA125 level after the first chemotherapy cycle was the most significant independent prognostic factor for overall survival (OS). Time to normalization (p=0.028) and relative percentage change between CA125 levels at baseline and after the first chemotherapy cycle (p=0.021) were additional independent prognostic factors in terms of OS. The CA125 level after the first chemotherapy cycle (p=0.001) and time to normalization (p<0.001) were identified as independent prognostic factors for progression free survival (PFS). CONCLUSION Among well-established CA125-related prognostic factors, serum CA125 levels after the first cycle of chemotherapy and time to normalization were the most significant prognostic factors for both OS and PFS.

Abstract
OBJECTIVE To investigate the role of CA-125 percent reduction after neoadjuvant chemotherapy in predicting the extent of the interval debulking surgery (IDS) and outcomes in patients with advanced-stage müllerian carcinoma. METHODS Patients who received neoadjuvant chemotherapy for advanced-stage müllerian carcinoma from 2000 to 2013 were identified. Percent reduction in CA-125 was categorized into 2 groups: ≥ 90% (CA ≥ 90%) and <90% (CA < 90%) reduction from prechemotherapy to preoperative CA-125. RESULTS Of the 115 patients identified, 73% had CA ≥ 90% and 27% had CA < 90%. Optimal and complete IDS were achieved in 87% and 38%, respectively. Compared with the CA < 90% group, the CA ≥ 90% group was more likely to have complete IDS (P = 0.035), less likely to have a bowel resection (P < 0.001), and more likely to have no viable tumor/microscopic disease with treatment effect (P < 0.001). No difference in overall survival (OS; P = 0.81) and progression-free survival (PFS; P = 0.60) was noted between the groups. In multivariable analysis, CA ≥ 90% was not a predictor of PFS (hazard ratio [HR], 1.08; 95% confidence interval [CI], 0.65-1.79; P = 0.77) or OS (HR, 1.45; 95% CI, 0.73-2.9; P = 0.29). Patients with preoperative CA-125 < 20 had significantly longer OS (P = 0.05) and PFS (P = 0.005) than did those with preoperative CA-125 ≥ 20. In multivariable analysis, preoperative CA-125 < 20 was a predictor of PFS (HR, 0.37; 95% CI, 0.20-0.66; P < 0.001) but not OS (HR, 0.64; 95% CI, 0.34-1.21; P = 0.17). CONCLUSIONS A reduction in CA-125 of at least 90% is associated with complete IDS, favorable pathologic response, and fewer bowel resections. A preoperative CA-125 < 20 suggests improved outcome. These findings are helpful for treatment planning and patient counseling.

Abstract
Because the majority of patients present advanced disease at diagnosis, the management of epithelial ovarian cancer needs specialist multidisciplinary teamwork. Expertise in surgery, chemotherapy, imaging and histopathology is essential to achieve optimum outcomes. Computed tomography scans are routinely used to determine the extent of disease and to aid in surgical planning. The histologic classification is crucial to plan the best therapeutic strategy and to define the prognosis of disease. Pathological prognostic factors, such as degree of differentiation, FIGO-stage, and histological type have to be described. This report is fundamental to assessing prognosis and selection of appropriate treatment strategy. An adequate staging procedure is an extensive staging by an experienced gynecological oncologist, exploring the entire upper abdomen, and the pelvic and para-aortic lymph node regions to define the Peritoneal Cancer Index (PCI). The final assessment is the completeness of cytoreduction (CC) score, which is an assessment of residual disease after a maximal surgical effort. Initial management of advanced ovarian cancer is best provided by a specialist multidisciplinary team, including a radiologist, a pathologist, a gynecologic oncologist and a medical oncologist.

Abstract
Changes in serum tumor biomarkers may indicate treatment efficacy. Traditional tumor markers may soon be replaced by novel serum biomarkers, such as circulating tumor cells (CTCs) or circulating tumor nucleic acids. Given their promising predictive values, studies of their kinetics are warranted. Many methodologies meant to assess kinetics of traditional marker kinetics during anticancer treatment have been reported. Here, we review the methodologies, the advantages and the limitations of the analytical approaches reported in the literature. Strategies based on a single time point were first used (baseline value, normalization, nadir, threshold at a time t), followed by approaches based on two or more time points [half-life (HL), percentage decrease, time-to-events…]. Heterogeneities in methodologies and lack of consideration of inter- and intra-individual variability may account for the inconsistencies and the poor utility in routine. More recently, strategies based on a population kinetics approach and mathematical modeling have been reported. The identification of equations describing individual kinetic profiles of biomarkers may be an alternative strategy despite its complexity and higher number of necessary measurements. Validation studies are required. Efforts should be made to standardize biomarker kinetic analysis methodologies to ensure the optimized development of novel serum biomarkers and avoid the pitfalls of traditional markers.

Abstract
PURPOSE Ovarian cancer is the sixth common cancer in women in developed countries. In severe cases, the optimal debulking is necessary. In order to increase optimal debulking and reduce preoperative complications, neoadjuvant chemotherapy followed by debulking surgery, and then chemotherapy again is introduced as substitute for primary surgery. In this study, we aim to evaluate perioperative outcome after neoadjuvant chemotherapy with carboplatin/paclyaxol in comparison with primary cytoreduction in patients with advanced ovarian cancer. METHODS In this prospective study, 60 patients with advanced ovarian cancer due to the disease severity were assigned into neoadjuvant chemotherapy (n = 30) or control (n = 30) groups. In neoadjuvant chemotherapy group, patients received three cycles of carboplatin (5-6 area under the curve) and paclitaxel (175 mg/m(2)) preoperatively followed by interval surgery. The control group received primary surgery plus adjuvant chemotherapy. Preoperative outcome was compared between groups. RESULTS Neoadjuvant group had significantly lower mean levels of CA 125 (p = 0.01) and less severe bleeding (p = 0.03) than control group. There was no significant difference between surgery time, preoperative complications, residual mass less than 1 cm, and hospital stay between groups. There was no mortality during the study. CONCLUSION Neoadjuvant chemotherapy caused less severe bleeding, but has no effect in decreasing complications after surgery; however, neoadjuvant chemotherapy followed by interval debulking surgery was not superior to primary debulking surgery followed by chemotherapy as a treatment option for patients with advanced ovarian carcinoma in this study.

[PMID: 23653831 PMCID: PMC3644690 DOI: 10.3802/jgo.2013.24.2.141] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2012] [Revised: 10/29/2012] [Accepted: 10/30/2012] [Indexed: 11/30/2022] Open
Abstract
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.

Abstract
OBJECTIVES To compare the survival and perioperative morbidity between primary debulking surgery (PDS) and neoadjuvant chemotherapy followed by interval debulking surgery (NAC/IDS) in treating patients with advanced epithelial ovarian cancer (EOC). METHODS We retrospectively reviewed 67 patients with stage IIIC or IV EOC treated at Peking University Cancer Hospital from January 2006 to June 2009. Wherein, 37 and 30 patients underwent PDS and NAC/IDS, respectively. RESULTS No difference in overall survival (OS) or progression-free survival (PFS) was observed between NAC/IDS group and PDS group (OS: 41.2 vs. 39.1 months, P=0.23; PFS: 27.1 vs. 24.3 months, P=0.37). The optimal debulking rate was 60% in the NAC/IDS group, which was significantly higher than that in the PDS group (32.4%) (P=0.024). The NAC/IDS group had significantly less intraoperative estimated blood loss and transfusion, lower nasogastric intubation rate, and earlier ambulation and recovery of intestinal function than the PDS group (P<0.05). CONCLUSIONS NAC/IDS is less invasive than PDS, and offers the advantages regarding optimal cytoreduction rate, intraoperative blood loss, and postoperative recovery, without significantly impairing the survival compared with PDS in treating patients with stage IIIC or IV EOC. Therefore, NAC/IDS may be a valuable treatment alternative for EOC patients.

Abstract
Objective To assess whether there is an association between improvement of computed tomography imaging results prior to interval debulking with survival in patients treated by neoadjuvant chemotherapy. Methods The clinical and outcome data of all advanced ovarian, primary peritoneal and tubal carcinoma patients who after diagnosis had neoadjuvant chemotherapy and underwent interval debulking during the period 2000-2010, were abstracted. Results of computed tomography imaging at diagnosis and prior to interval debulking were compared. Two parameters were assessed: the change of the size and number of abnormal findings and the change in the amount of ascites. CA-125 level response was also calculated. An assessment of progression free survival and of survival by the Kaplan-Meier method was made according to the change in computed tomography imaging results and according to response of CA-125 levels. Results The median progression free survival and the median survival of the 37 study group patients were 7.9 and 49.2 months respectively. No significant difference in progression free survival and survival was observed between patients with marked improvement in the computed tomography results and those with less desirable results (7.93 vs. 7.23 months respectively, p=0.89; 45.8% vs. 52.5% months respectively, p=0.95). There were also no statistically significant difference according to CA-125 level response. Conclusion It seems that neither improvement in imaging results nor CA-125 level response can predict the survival of ovarian carcinoma patients prior to interval debulking after neoadjuvant chemotherapy.

Abstract
CA 125 is the most sensitive and the most used marker in the management of ovarian cancer at various stages of the disease. CA 125 is used at the time of diagnosis of the disease, to evaluate the possibility of complete resection during surgery, to estimate sensibility for adjuvant or neo-adjuvant chemotherapy and for diagnosis of recurrences. CA 125 has a diagnostic and therapeutic value and could be of help during therapeutic evaluation. CA 125 has been the topic of many studies for optimizing the management of epithelial ovarian cancers. Mandatory before any ovarian surgery, serum CA 125 levels is a help for the determination of the appropriate surgery. It appears to be a help in choosing therapeutic strategy, to predict optimal surgery and also global and progression-free survival. Low preoperative rates, half-life and fast normalization of CA 125 during the adjuvant chemotherapy are correlated with an optimal surgery and a better global and progression-free survival. The normal range of CA 125 is a strong predictive factor for disease recurrence even if its role in survival has not yet been determined. The dosage of CA 125 and its dynamic interpretation is an indispensable approach to the diagnosis, therapeutics and follow-up of ovarian cancer. Simple serum CA 125 concentration is a very important prognostic and predictive factor for a personalized care.

Abstract
PURPOSE To assess the significance of CA-125 regression as a prognostic indicator and predictor of optimal cytoreduction at interval debulking surgery (IDS) in women with ovarian or primary peritoneal carcinoma receiving neoadjuvant chemotherapy (NAC). METHODS 63 women treated between 2004 and 2007 with neoadjuvant platinum-based chemotherapy followed by IDS were studied retrospectively. Pre-operative CA-125 values were used to calculate a regression coefficient (CA-125r) using exponential regression analysis. Outcome endpoints were overall survival (OS), time to CA-125 progression (TTC) by Rustin criteria and time to second-line treatment (TTS). RESULTS Women with a CA-125 half-life greater than 18 days had a significantly worse OS compared to those with a half-life less than 12 days on univariate testing (HR 3.34, 95% CI 1.25-8.94, p = 0.017). On multivariable analysis, CA-125r was an independent predictor of OS [HR 1.18 (per 0.01 increase in CA-125r), 95% CI 1.01-1.40, p = 0.043]. CA-125r was independently predictive of TTC and TTS (HR 1.17, p ≈ 0.03 for each). CA-125r was also predictive of achieving optimal cytoreduction at IDS (AUC 0.756, p < 0.001). CONCLUSIONS CA-125 regression rate during pre-operative NAC is of independent prognostic value. CA-125 regression rate strongly predicts for optimal cytoreduction.
