Purpose To assess whether six courses of paclitaxel are effective as consolidation treatment in patients with advanced epithelial ovarian cancer who are in complete response after first-line paclitaxel/platinum–based chemotherapy. Patients and Methods Patients with stages IIb to IV disease in clinical or pathologic complete response after six courses of paclitaxel/platinum–based chemotherapy were randomly allocated to either observation (ie, control) or six courses of paclitaxel 175 mg/m2 every 3 weeks (ie, maintenance). Results Two hundred patients were randomly assigned from March 1999 to July 2006. Because of the low accrual rate, an unplanned interim analysis of futility according to the Bayesian approach was performed. Grade 2 or greater motor neurotoxicity and sensory neurotoxicity were reported in 11.3% and 28.0% of the paclitaxel-arm patients, respectively. After a median follow-up of 43.5 months, 107 patients (53%) had experienced relapse, and 48 patients (24%) had died. Two-year progression-free survival rates were 54% (95% CI, 43% to 64%) and 59% (95% CI, 49% to 69%; P = not significant) in the control and maintenance arms, respectively. Corresponding 2-year overall survival rates were 90% (95% CI, 84% to 97%) and 87% (95% CI, 80% to 94%; P = not significant), respectively. The Cox model showed that residual disease after initial surgery (macroscopic v no macroscopic residuum; hazard ratio [HR], 1.91; 95%CI, 1.21 to 3.03) and stage (IIIc to IV v others; HR, 3.10; 95% CI, 1.13 to 8.48) were independent prognostic factors for progression-free survival, whereas the treatment arm (maintenance v control) had no prognostic relevance. Conclusion A consolidation treatment with six cycles of paclitaxel does not prolong progression-free survival or overall survival in patients in complete response after first-line paclitaxel/platinum–based regimens.

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.

Oligometastatic Disease

IntroductionData supporting stereotactic body radiotherapy for oligometastatic patients are increasing; however, the outcomes for gynecological cancer patients have yet to be fully explored. Our aim is to analyze the clinical outcomes of stereotactic body radiotherapy in the treatment of patients with recurrent or oligometastatic ovarian cancer or cervical cancer.MethodsThe clinical data of 29 patients (35 lesions) with oligometastatic cervical cancer (21 patients, 72%) and ovarian carcinoma (8 patients, 28%) who were treated with stereotactic body radiotherapy for metastatic sites were retrospectively evaluated. All patients had <5 metastases at diagnosis or during progression, and were treated with stereotactic body radiotherapy for oligometastatic disease. Patients with ≥5 metastases or with brain metastases and those who underwent re-irradiation for primary site were excluded. Age, progression time, mean biologically effective dose, and treatment response were compared for overall survival and progression-free survival.ResultsA total of 29 patients were included in the study. De novo oligometastatic disease was observed in 7 patients (24%), and 22 patients (76%) had oligoprogression. The median follow-up was 15.3 months (range 1.9–95.2). The 1 and 2 year overall survival rates were 85% and 62%, respectively, and the 1 and 2 year progression-free survival rates were 27% and 18%, respectively. The 1 and 2 year local control rates for all patients were 84% and 84%, respectively. All disease progressions were observed at a median time of 7.7 months (range 1.0–16.0) after the completion of stereotactic body radiotherapy. Patients with a complete response after stereotactic body radiotherapy for oligometastasis had a significantly higher 2 year overall survival and progression-free survival compared with their counterparts. In multivariate analysis, early progression (≤12 months) and complete response after stereotactic body radiotherapy for oligometastasis were the significant prognostic factors for improved overall survival. However, no significant factor was found for progression-free survival in the multivariable analysis. No patients experienced grade 3 or higher acute or late toxicities.ConclusionsPatients with early detection of oligometastasis (≤12 months) and with complete response observed at the stereotactic body radiotherapy site had a better survival compared with their counterparts. Stereotactic body radiotherapy at the oligometastatic site resulted in excellent local control rates with minimal toxicity, and can potentially contribute to long-term survival.

5551 Background: There is a continuing debate over the role of combination, platinum-based chemotherapy for PS, recurrent ovarian cancer (OC). Although this phase 3 trial was closed prematurely by the SWOG Data Safety and Monitoring Committee (DSMC) due to slow patient accrual, it provided provocative results nonetheless. Methods: Patients with recurrent stage III or IV OC, with a progression-free and platinum-free interval of 6- 24 months after completion of first-line platinum-based chemotherapy, and up to 12 courses of non-platinum containing chemotherapy or biologic therapy as consolidation treatment after the first-line regimen were eligible and observed for progression-free survival (PFS) and overall survival (OS). Patients were randomized to either IV PLD (30 mg/m2) plus IV carboplatin (AUC=5 mg/mL × min) once every 4 weeks (PLD arm) or IV carboplatin (AUC=5mg/ML × min) once every four weeks alone. Results: The PLD arm enrolled 31 patients and the carboplatin alone arm enrolled 30 for a total of 61 patients out of the 900 planned. The response rates were 67% (18/27) for the PLD arm and 32% (9/28) for the carboplatin only arm (Fisher’s exact p=0.02). The estimated median PFS on the PLD arm was 12 months and 8 months on the carboplatin only arm. The estimated median OS on the PLD arm was 26 months and 18 months on the carboplatin only arm (p=0.02). 26% of the patients on the PLD arm reported grade 4 toxicities, all hematological in nature. Conclusions: Although this study was closed early, because of slow patient accrual the results for the PLD arm are intriguing for response rates, median progression-free survival and overall survival. These data suggest that there may be an advantage to the PLD plus carboplatin combination treatment in patients with PS, recurrent disease. No significant financial relationships to disclose.

One hundred twenty-eight patients with purely nodular lymphocytic poorly differentiated lymphoma (NLPDL) without any prior therapy, entered on Eastern Cooperative Oncology Group protocol EST 2474, were analyzed for response, progression-free and overall survival. The restaged complete response rates with cyclophosphamide-prednisone (CP) (moderate regimen) of 54% compared favorably with those of the more intensive regimens; cyclophosphamide, vincristine, procarbazine and prednisone (COPP) (56%) and BCNU, cyclophosphamide, vincristine, and prednisone (BCVP) (53%). The toxicity of the regimens decreased from BCVP to COPP to CP. The median survival rate for the entire group was 7.8 years. Estimated progression-free survival at five years by regimen was COPP, 57%; BCVP, 26%; CP, 22% (P = .02). No other prognostic parameter significantly affected progression-free survival. In spite of the better progression-free survival of COPP-treated patients, the overall survival rates with the different induction regimens were similar. Maintenance therapy for patients in complete response at the end of induction therapy with periodic BCVP reinduction did not significantly affect the disease-free or overall survival. Cyclophosphamide-prednisone is a minimally toxic regimen effective in the treatment of NLPDL, but COPP, in view of its acceptable toxicity in this patient population and apparent superiority in providing a longer disease-free state, deserves further testing.

Abstract Background The efficacy and safety of bevacizumab-containing chemotherapy for patients with metastatic duodenal and jejunal adenocarcinoma (mDJA) are unclear. The present study aimed to evaluate the efficacy of bevacizumab and to explore immunohistochemical markers that can predict the efficacy of bevacizumab for patients with mDJA. Methods This multicentre study included patients with histologically confirmed small bowel adenocarcinoma who received palliative chemotherapy from 2008 to 2017 at 15 hospitals. Immunostaining was performed for vascular endothelial growth factor-A (VEGF-A), TP53, Ki67, β-catenin, CD10, MUC2, MUC5AC, MUC6, and mismatch repair proteins. Results A total of 74 patients were enrolled, including 65 patients with mDJA and 9 with metastatic ileal adenocarcinoma. Patients with mDJA who received platinum-based chemotherapy with bevacizumab as first-line treatment tended to have a longer progression-free survival and overall survival than those treated without bevacizumab (P = 0.075 and 0.077, respectively). Multivariate analysis extracted high VEGF-A expression as a factor prolonging progression-free survival (hazard ratio: 0.52, 95% confidence interval: 0.30–0.91). In mDJA patients with high VEGF-A expression, those who received platinum-based chemotherapy with bevacizumab as a first-line treatment had significantly longer progression-free survival and tended to have longer overall survival than those treated without bevacizumab (P = 0.025 and P = 0.056, respectively), whereas no differences were observed in mDJA patients with low VEGF-A expression. Conclusion Immunohistochemical expression of VEGF-A is a potentially useful biomarker for predicting the efficacy of bevacizumab-containing chemotherapy for patients with mDJA.

IntroductionThe role of cytoreductive surgery in the poly-ADP ribose polymerase inhibitors era is not fully investigated. We evaluated the impact of surgery performed prior to platinum-based chemotherapy followed by olaparib maintenance in platinum-sensitive BRCA-mutated recurrent ovarian cancer.MethodsThis retrospective study included platinum-sensitive recurrent ovarian cancer BRCA-mutated patients from 13 Multicenter Italian Trials in Ovarian cancer and gynecological malignancies centers treated between September 2015 and May 2019. The primary outcomes were progression-free survival and overall survival. Data on post-progression treatment was also assessed.ResultsAmong 209 patients, 72 patients (34.5%) underwent cytoreductive surgery followed by platinum-based chemotherapy and olaparib maintenance, while 137 patients (65.5%) underwent chemotherapy treatment alone. After a median follow-up of 37.3 months (95% CI: 33.4 to 40.8), median progression-free survival in the surgery group was not reached, compared with 11 months in patients receiving chemotherapy alone (P<0.001). Median overall survival was nearly double in patients undergoing surgery before chemotherapy (55 vs 28 months, P<0.001). Post-progression therapy was assessed in 127 patients: response rate to chemotherapy was 29.2%, 8.8%, and 9.0% in patients with platinum-free interval >12 months, between 6 and 12 months, and <6 months, respectively.ConclusionCytoreductive surgery performed before platinum therapy and olaparib maintenance was associated with longer progression-free survival and overall survival in BRCA-mutated platinum-sensitive relapsed ovarian cancer patients. In accordance with our preliminary results, the response rate to chemotherapy given after progression during olaparib was associated with platinum-free interval.
