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.

PURPOSE: To determine whether precise definitions of response based on serial CA-125 levels can predict the activity of drugs in phase II trials for ovarian cancer as accurately as standard criteria. PATIENTS AND METHODS: Fourteen different drugs for relapsed ovarian cancer were analyzed in 25 treatment groups in 19 clinical trials. Response rates were estimated in 1,457 assessable patients according to standard criteria and in 1,092 assessable patients according to CA-125. For each drug trial, the observed response rates acted as the input data for an evaluation of how the two criteria would perform in a hypothetical Gehan two-stage phase II trial, accepting a target drug efficacy rate of 20% and a rejection error of 5%. RESULTS: CA-125 and clinical response criteria were concordant in 20 of the 25 groups, with less than 5% chance of rejecting the drug in nine groups and greater than 5% in 11 groups. In four groups, the drug had less than 5% chance of being rejected by CA-125 but greater than 5% chance of being rejected by standard criteria. The difference in the classification of drugs by the standard and CA-125 response criteria was not statistically significant (P = .38, McNemar’s test). CA-125 response rates were slightly higher than standard response rates by a factor of 1.11. CONCLUSION: Definitions based on a 50% or 75% decrease of CA-125 levels accurately predicted which drugs in phase II trials for relapsed ovarian cancer were active and justified further investigation.

PURPOSE: A prospective, nonrandomized, multicenter, open feasibility study of cisplatin and docetaxel as first-line chemotherapy in International Federation of Gynecology and Obstetrics (FIGO) stage IC-IV epithelial ovarian cancer was conducted. The primary end point was the incidence of severe fluid retention that necessitated treatment withdrawal. PATIENTS AND METHODS: Cisplatin and docetaxel were administered every 3 weeks for six planned cycles, with a 5-day prophylactic dexamethasone regimen (8 mg two times per day). One hundred patients (median age, 53 years; range, 24 to 71 years) received a total of 512 cycles of chemotherapy in two cohorts: cohort 1, 49 patients, 258 cycles (cisplatin 75 mg/m2 and docetaxel 75 mg/m2); cohort 2, 51 patients, 254 cycles (cisplatin 75 mg/m2 and docetaxel 85 mg/m2). RESULTS: No patients were taken off study because of fluid retention. Sixty-six patients completed six cycles of protocol therapy; 16 stopped early because of toxicity (neurotoxicity in six patients, nephrotoxicity in three, neutropenia in two, and hypersensitivity, diarrhea and vomiting, skin rash, clinical deterioration, and patient's wishes in one patient each). Grade 3/4 neutropenia was observed in more than 75% of patients and seemed to be cumulative. Patients in cohort 2 had significantly more severe neutropenia and lethargy than those in cohort 1. In addition, there were five treatment-related deaths in cohort 2 (three neutropenia and two upper gastrointestinal hemorrhage). Neurotoxicity (mainly sensory, > grade 1) was observed in 23 patients. The overall clinical response rate was 69% (complete response, 38%; partial response, 31%); CA-125 response rate was 73%. Median progression-free survival for the group was 12 months. CONCLUSION: Cisplatin and docetaxel can be administered at doses of 75 mg/m2 and 75 mg/m2, respectively, every 3 weeks, and the utility of this regimen is not limited by fluid retention. However, 33 of 100 patients were unable to complete the planned six cycles, which may explain, in part, the poor overall progression-free survival. Increasing the docetaxel dose to 85 mg/m2 adds unacceptable hematologic toxicity and potential risks to the patient.

ObjectiveMost patients with epithelial ovarian cancer achieve a complete clinical remission (CCR) with normal CA-125 but will still relapse and die from their disease. The present study was designed to determine whether CA-125 levels before, during, and after primary treatment provide prognostic information for both type I and type II ovarian cancer.MethodsIn this retrospective study, we identified 410 patients with epithelial ovarian cancer who had achieved a CCR between 1984 and 2011. A Cox proportional hazards model and log-rank test were used to assess associations between the nadir CA-125, histotype, and prognosis.ResultsThe baseline serum CA-125 concentration was higher in patients with type II ovarian cancer than in those with type I ovarian cancer (P < 0.001). The nadir CA-125 was an independent predictor of progression-free survival (PFS; P < 0.001) and overall survival (OS; P = 0.035) duration. The PFS and OS durations were 21.7 and 79.4 months in patients with CA-125 of 10 U/mL or less and 13.6 and 64.6 months in those with CA-125 of 11 to 35 U/mL, respectively (P = 0.01 and P = 0.002, respectively). Histotype was an independent predictor of PFS (P = 0.041): the PFS and OS durations of the patients with type I ovarian cancer were longer than those of the patients with type II ovarian cancer (P < 0.001 and P < 0.001, respectively).ConclusionsThe nadir CA-125 and histotype are predictive of PFS and OS durations in patients with ovarian cancers who experienced a CCR. Progression-free survival and OS durations were shorter in the patients with CA-125 levels of 11 to 35 U/mL and type II disease than in those with CA-125 levels of 10 U/mL or less and type I ovarian cancer.

IntroductionTo evaluate the incidence of anemia in patients with epithelial ovarian cancer receiving paclitaxel-carboplatin combination therapy (TC) using data from the Japanese Gynecologic Oncology Group (JGOG) 3016 trial, and to examine the effect of severe anemia on survival during dose-dense TC.MethodsRetrospective analysis was conducted in patients enrolled in the JGOG 3016 trial who underwent at least one cycle of the protocol therapy (n = 622). Hemoglobin values at enrollment and during each cycle of TC were collected. One-to-one matching was performed between patients with and patients without grade 3/4 anemia during TC (anemia and nonanemia groups) to adjust the baseline characteristics of the patients. The cumulative survival curve and median progression-free survival were estimated using the Kaplan-Meier method.ResultsGrades 2 to 4 anemia was observed in 19.8% of patients before first-line TC. The incidence of grade 3/4 anemia rapidly increased to 56.1% after the fourth cycle of dose-dense TC. After matching, the median progression-free survival in the anemia (hemoglobin <8.0 g/dL) and nonanemia (hemoglobin >8.0 g/dL) groups was 777 and 1100 days, respectively (P = 0.3493) for patients receiving dose-dense TC. The median progression-free survival in patients receiving conventional TC was similar between the 2 groups.ConclusionsThe difference in progression-free survival between patients with epithelial ovarian cancer with and those without severe anemia during TC was not statistically significant, but for patients receiving dose-dense TC, severe anemia seems to have prognostic relevance. Prospective trials are needed to investigate whether the optimal management of chemotherapy-induced anemia, including appropriate use of erythropoiesis-stimulating agents, would further improve the survival of patients with ovarian cancer receiving dose-dense TC.

5568 Background: Cremorphor EL, used to enhance drug solubility, may add to paclitaxel’s toxicities such as hypersensitivity reactions or peripheral neuropathy. This multi-institutional phase II trial is to evaluate the efficacy and safety of Cremophor-Free, Polymeric Micelle Formulation of Paclitaxel (Genexol-PM) compared to Paclitaxel (Genexol) as a combined chemotherapy with carboplatin in patients with advanced epithelial ovarian cancer. Methods: In this phase II, randomized, parallel study, patients with FIGO stage IC-IV epithelial ovarian cancer after debulking surgery received intravenously Genexol-PM 260 mg/m2 or Genexol 175 mg/m2 combined with carboplatin iv (AUC 5) on day 1 of every 3-week cycle for a maximum of six cycles. The primary endpoint was composite response by GCIG CA-125 Response and Response Evaluation Criteria In Solid Tumors (RECIST). Secondary and exploratory endpoints included overall survival, progression-free survival, time to tumor progression, and safety and tolerability. Results: A total of 102 patients were randomized to Genexol-PM plus carboplatin (n = 51) or Genexol plus carboplatin (n = 51). Composite response rate in patients with or without measurable disease was 88.0% in the Genexol-PM plus carboplatin group and 77.1% in the Genexol plus carboplatin group. Noninferiority of Genexol-PM plus carboplatin compared with Genexol plus carboplatin was confirmed for composite response rate by CA-125/RECIST criteria. There were no differences in progression-free survival and overall tumor progression between the groups. Although there was a higher rate of grade 3 neutropenia in the Genexol-PM plus carboplatin group, the overall rate of hemodynamic adverse events was comparable between the 2 groups. There was no difference in peripheral neuropathy and hypersensitivity. No unexpected safety concerns were identified in this study. Conclusions: High-dose of Genexol-PM in combination with carboplatin was well tolerated, and its response rate was noninferior to that of Genexol plus carboplatin in patients with advanced epithelial ovarian cancer. Clinical trial information: NCT01276548.

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.

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.
