The Impact

5055 Background: There has been conflicting data regarding the relationship between obesity and progression free survival in patients with ovarian cancer. There has been some evidence to suggest that obesity results in altered tumor biology and a poorer prognosis in these patients. The aim of this study was to examine whether obesity is a risk factor for time to recurrence in primary epithelial ovarian cancer. Methods: A multicenter retrospective chart review was performed at Mercy Medical Center and University of Michigan Medical Center. 591 patients were diagnosed with primary epithelial ovarian cancer between 2004-2009. However, 221 patients were excluded from the analysis because of persistent or progressive disease, treatment with neoadjuvant chemotherapy, presence of synchronous tumors or incomplete follow-up data. 370 patients were eligible for analysis. Data collected included: height and weight at the time of surgery, age, race, medical co-morbid illnesses, tumor stage, grade and histology. Treatment related data such as number of cycles of adjuvant chemotherapy; and optimal versus suboptimal tumor debulking was also collected. Body mass index (BMI) was defined according to WHO 2004 criteria. Women with a BMI greater than 30 were categorized as obese. The diagnosis of recurrence was made by positive radiological or pathological diagnosis of cancer recurrence after patient had surgery, received adjuvant chemotherapy and had no clinical, radiological or serological evidence of recurrence during this time. The time to recurrence was then quantified in terms of months from the initial surgery. Survival analyses were performed with the Kaplan-Meier method and compared using log-rank testing. Time to recurrence was analyzed using Mann-Whitney U and Wilcox W tests. Results: 130 (35%) obese patients were compared with 240 (65%) non obese patients. A recurrence was documented in 125 (47.9%) non obese patients and 49 (37.7%) obese patients. Time to recurrence between both BMI groups was found to be identical, at 15 months (p=1.0). The progression free survival was similar in both obese and non obese subjects (p=0.118). Conclusions: Obesity does not impact the time to recurrence in patients with primary ovarian cancer.

The Impact

Aim. The purpose of the present study was to analyze the predictive and prognostic role of soluble (pro)renin receptor (sPRR) as a biomarker for clinicopathological outcome in patients with primary epithelial ovarian cancer (EOC). As part of the renin-angiotensin system (RAS) whose activity is known to increase in ovarian cancer patients, the relation of sPRR and ovarian cancer should be further investigated.Patients and Methods. In this study 197 patients with primary EOC in our institution from 2000 to 2011 were included. sPRR was determined by enzyme-linked immunosorbent assay (ELISA) in preoperative taken blood sera. Associations with clinicopathological outcome were analyzed and serum levels of sPRR in patients have been compared to those in healthy specimen. Kaplan-Meier and logistic/Cox regression assessed the impact of the markers on progression-free survival (PFS) and overall survival (OS).Results. There have been no correlations proved of sPRR levels with neither clinicopathological factors nor prognostic data. Also the distribution of sPRR in patients and controls was normal.Conclusion. sPRR seems to have no predictive, prognostic, or diagnostic value in EOC. As several factors of the RAS which might indicate cancer events have been shown, sPRR seems not to be affected.

ObjectiveTo investigate the efficacy and safety of hu3S193, a humanized anti-Lewis-Y monoclonal antibody, as a consolidation strategy in patients with platinum-sensitive recurrent epithelial ovarian cancer who achieved a second complete response after salvage platinum-doublet chemotherapy.MethodsThis single-arm phase II study accrued patients with recurrent epithelial ovarian cancer with Lewis-Y expression by immunohistochemistry who had achieved a second complete response after five to eight cycles of platinum-based chemotherapy. Patients received intravenous infusions of hu3S193, 30 mg/m2 every 2 weeks starting no more than 8 weeks after the last dose of chemotherapy and continuing for 12 doses, until disease progression, or unacceptable toxicity. The primary endpoint was progression-free survival of the second remission. Secondary objectives were safety and pharmacokinetics.ResultsTwenty-nine patients were enrolled. Most had a papillary/serous histology tumor (94%), stage III disease at diagnosis (75%), and five (17%) underwent secondary cytoreduction before salvage chemotherapy. Two patients were not eligible for efficacy but were considered for toxicity analysis. Eighteen patients (62%) completed the full consolidation treatment while nine patients progressed on treatment. At the time of analysis, 23 patients (85%) of the eligible population had progressed and seven of these patients (26%) had died. Median progression-free survival of the second remission was 12.1 months (95% CI: 10.6–13.9), with a 1-year progression-free survival of the second remission rate of 50.1%. The trial was terminated early since it was unlikely that the primary objective would be achieved. The most commonly reported treatment-related adverse events were nausea (55%) and vomiting (51%).ConclusionsHu3S193 did not show sufficient clinical activity as consolidation therapy in patients with recurrent epithelial ovarian cancer who achieved a second complete response after platinum-based chemotherapy.Trial registrationNCT01137071.

The Impact

<b><i>Background:</i></b> We evaluated the prognostic impact of various global health assessment tools in patients older than 60 years with ovarian cancer (OC). <b><i>Methods:</i></b> G-8 geriatric screening tool (G-8 score), Lee Schonberg prognostic index, Eastern Cooperative Oncology Group (ECOG) performance status, and Charlson Comorbidity Index (CCI) were determined retrospectively in a consecutive cohort of elderly patients with OC. Univariate and multivariate Cox regression analyses and Kaplan-Meier method were performed to analyze the impact of the preoperative global health status on survival. <b><i>Results:</i></b> 116 patients entered the study. In multivariate analysis adjusted for clinical-pathological factors, only the G-8 score retained significance as a prognostic parameter of progression-free survival (PFS) (hazard ratio [HR]: 1.970; 95% confidence interval [CI] [1.056–3.677]; <i>p</i> = 0.033). Fifty-six patients were classified as G-8-nonfrail with an increased PFS compared to 50 G-8-frail patients (53.4% vs. 16.7%; <i>p</i> = 0.010). A higher CCI was associated with decreased PFS (45.1% vs. 22.2%; <i>p</i> = 0.012), but it did not influence the risk of recurrences or death (<i>p</i> = 0.360; <i>p</i> = 0.111). The Lee Schonberg prognostic index, the ECOG, and age were not associated with survival. <b><i>Conclusions:</i></b> The G-8 score independently predicted PFS in elderly OC patients regardless of maximal surgical effort. Thus, it could be useful to assess surgical treatment based on frailty rather than age alone.

CD44, a surface marker for cancer stem cells, interacts with PKM2, a key regulator of aerobic glycolysis, and enhances the glycolytic phenotype of cancer cells leading to antioxidant protection and macromolecules’ synthesis. To clarify the clinical importance of this “cross-talk” as a mechanism of drug resistance, we assessed the expression both of PKM2 and of CD44 in cancer cells of patients with epithelial ovarian cancer (EOC) treated with platinum-based treatment. One hundred and seventy-one patients with EOC were assessed for PKM2mRNA expression and PKM2 and CD44 proteins detection. Associations with progression-free survival (PFS) and overall survival (OS) were assessed with Kaplan–Meier and adjusted Cox regression models. PKM2mRNA and protein as well as CD44 protein were detectable in the majority of patients. Positive correlation between PKM2 and CD44 protein expression was observed (Spearman rho = 0.2, p = 0.015). When we used the median to group patients into high versus low expression, high PKM2mRNA and protein levels were significantly associated with lower progression-free survival (PFS; p = 0.003 and p = 0.002, respectively) and shorter overall survival (OS; p ≤ 0.001 and p = 0.001, respectively). However, high CD44 protein expression was significantly correlated only with shorter OS (p = 0.004). Moreover, patients with both high PKM2 and CD44 protein levels experienced shorter PFS and OS (p = 0.007 and p = 0.003, respectively) compared to patients with low expression of both proteins. Finally, higher PKM2mRNA and protein expression as well as CD44 protein expression (HR: 2.16; HR: 1.82; HR: 1.01, respectively) were independent prognostic factors for decreased median OS (mOS), whereas only PKM2 protein expression (HR: 1.95) was an independent prognostic factor for decreased median PFS (mPFS). In conclusion, PKM2 expression is a negative prognostic factor in EOC patients, but the interaction between CD44 and PKM2 that may be implicated in EOC platinum-resistance needs further investigation.

Standard Response

PURPOSE: To assess CA-125 as a measure of response in patients treated with paclitaxel. PATIENTS AND METHODS: One hundred forty-four patients treated with paclitaxel derived from four different trials and 625 patients treated with platinum from two trials were analyzed using precisely defined 50% and 75% reductions in CA-125. The standard and CA-125 response rates to paclitaxel and platinum were compared. In addition, we analyzed individual patient groups in which there was a difference in response according to the two response criteria. RESULTS: Patients with stable disease as determined by standard criteria who were treated with platinum and responded according to CA-125 criteria have an improved median progression-free survival compared with patients with stable disease who did not respond according to CA-125 criteria (10.6 v 4.8 months; P < .001). Standard and CA-125 response rates for patients treated with platinum (58.93% v 61.31%, respectively) and paclitaxel (30.65% v 31.67%, respectively) were very similar, as were rates of false-positive prediction of response by CA-125 (platinum 2.2% and paclitaxel 2.9%). Responders to paclitaxel had a significantly improved progression-free survival compared with nonresponders by both standard criteria (median progression-free survival, 6.8 v 2.5 months; P < .001) and CA-125 criteria (median progression-free survival, 6.8 v 3.4 months; P < .001). CONCLUSION: For assessing activity of therapy for ovarian cancer, these data show that precise 50% or 75% CA-125 response criteria are as sensitive as standard response criteria. We propose that they may be used as a measure of response in lieu of or in addition to standard response criteria in clinical trials involving epithelial ovarian cancer. Sensitivity is maintained whether patients are treated with platinum or paclitaxel.

The Impact

Aim: To define the impact of polymorphisms in genes involved in platinum-taxane and estrogen activity in the outcome of platinum-based treated ovarian cancer patients (OCP). Patients & Methods: Two hundred and thirty OCP were analyzed for 124 germ-line polymorphisms to generate a prognostic score for overall survival (OS), progression-free survival (PFS) and platinum-free interval (PFI). Results: ABCG2 rs3219191D>I, UGT1A rs10929302G>A and UGT1A rs2741045T>C polymorphisms were significantly associated with all three parameters (OS, PFS and PFI) and were used to generate a score. Patients in high-risk group had a poorer OS (hazard ratio [HR]: 1.8; 95% CI: 1.3–2.7; p = 0.0019), PFS (HR: 2.0; 95% CI: 1.4–2.9; p < 0.0001) and PFI (HR: 1.9; 95% CI: 1.4–2.8; p = 0.0002) compared with those in low-risk group. Conclusion: The prognostic-score including polymorphisms involved in drug and estrogen pathways stratifies OCP according to OS, PFS and PFI.
