e16553 Background: The toxicity and efficacy of combined weekly topotecan and weekly bevacizumab in women with recurrent and progressive ovarian cancer. Methods: Reviewed data-base from 1/2003-present (1/2013) identified 15 patients who were treated with topotecan 4mg/m2 on days 1, 8, and 15 and bevacizumab 10mg/kg on days 1 and 15 of a 28-day cycle until progressive disease or excessive toxicity warranted discontinuation. The primary endpoint was progression-free survival. Results: Patients (n = 15) received a median of 4 treatment cycles. Mean number of previous chemotherapy regimens was 5 (range 2-9). Toxicity was generally mild, with neutropenia (20%), gastrointestinal toxicity (20%), pain (26%), anemia requiring transfusion (6%) being the most common adverse events. Two patients required dose adjustment secondary to neutropenia. Patients treated with 5 or more prior regimens had more adverse events, 66% vs. 33%, respectively. No febrile neutropenia or treatment-related deaths occurred. Median PFS and OS were 5.6 months and 5.9 months with 6 (40%) patients progression-free for ≥5 months. Two (13%) patients had complete response, 9 (60%) had stable disease or partial response and were still receiving the above mentioned treatment, and 4 (27%) had progressive disease. Conclusions: Treatment of recurrent and progressive ovarian cancer with weekly Topotecan and biweekly Bevacizumab demonstrates a viable efficacy with acceptable toxicity profile in women with previous multiple lines of treatment; as this becomes a more widely used regimen further investigation will be needed to determine early use of this well tolerated chemotherapy.

Whilst researches elucidating a diversity of intracellular mechanisms, platinum-resistant epithelial ovarian cancer (EOC) remains a major challenge in the treatment of ovarian cancer. Here we report that Exo70, a key subunit of the exocyst complex, contributes to both innate and acquired cisplatin resistance of EOC. Upregulation of Exo70 is observed in EOC tissues and is related to platinum resistance and progression-free survival of EOC patients. Exo70 suppressed the cisplatin sensitivity of EOC cells through promoting exocytosis-mediated efflux of cisplatin. Moreover, cisplatin-induced autophagy-lysosomal degradation of Exo70 protein by modulating phosphorylation of AMPK and mTOR, thereby reducing the cellular resistance. However, the function was hampered during prolonged cisplatin treatment, which in turn stabilized Exo70 to facilitate the acquired cisplatin resistance of EOC cells. Knockdown of Exo70, or inhibiting exocytosis by Exo70 inhibitor Endosidin2, reversed the cisplatin resistance of EOC cells both in vitro and in vivo. Our results suggest that Exo70 overexpression and excessive stability contribute to innate and acquired cisplatin resistance through the increase in cisplatin efflux, and targeting Exo70 might be an approach to overcome cisplatin resistance in EOC treatment.

16078 Background: Cytoreductive surgery followed by intraperitoneal hyperthermic chemoperfusion (CS/IPHC) has shown increased survival for patients with recurrent and persistent GI malignancies with peritoneal dissemination. We present our preliminary experience with CS/IPHC as palliative therapy for recurrent ovarian cancer treated at a single institution. Methods: A retrospective review of CS/IPHC for women with recurrent or persistent epithelial ovarian carcinoma previously treated with platinum/taxane chemotherapy at a single institution from 2002–2006 was performed. Each patient had an attempted optimal surgical debulking (volume of residual disease <1 cm) prior to chemoperfusion. IPHC was performed on all patients for 100 minutes at temperatures between 40–42°C with either mitomycin C (40 mg/m2) or cisplatin (100 mg/m2). Post-surgical complications were evaluated. End points analyzed included morbidity, progression free survival, and over all survival. Results: Thirty-two patients were identified, with optimal cytoreductive surgery obtained in 26 (81.3%). Procedures required for cytoreduction included omentectomy (n=16), splenectomy (n=14), colonic resection (n=14), small bowel resection (n=13), ileostomy (n=9), hepatic resection (n=5), partial gastrectomy (n=5), and diaphragmatic stripping (n=3). Over-all morbidity was 65.6%, with major morbidity of 9.4%. There were three mortalities within sixty days of operation. Common morbidities included neutropenia (n=5), ileus (n=5), pleural effusions (n=4), and sepsis (n=4). Median length of stay was 11 days (6 to 47). Nineteen patients had a documented recurrence with a median progression free survival of 8 months (1 to 22). Median survival was 13 months (1 to 54) for these patients with recurrent end stage ovarian cancer. Conclusions: CS/IPHC is associated with high morbidity, but acceptable mortality. In a subset of patients, survival is improved compared to historical controls for recurrent ovarian cancer. A randomized phase II study is planned based on this data. No significant financial relationships to disclose.

Abstract Purpose Naked2 (NKD2) is a negative regulator of Wnt signaling pathway and associates with transforming growth factor secretion. The role of NKD2 in ovarian cancer is unknown. Patients and methods Gene expression profiles were measured and compared in nine patients by RNA sequencing. NKD2 expressions in ovarian cancer were measured by reverse transcription polymerase chain reaction and western blot. Tissue slides of 79 patients were stained and scored for NKD2 expression. In vitro experiments were conducted to explore the role of NKD2 in ovarian cancer. The prognostic role of NKD2 was evaluated by survival analysis. Results NKD2 was upregulated in patients with better survival by mRNA and protein expression. Patients were classified as NKD2-high group (n = 30) and NKD2-low group (n = 49) according to immunohistochemical score. High NKD2 was correlated with lower recurrence rate (P = 0.002) and higher percentage of platinum-sensitive recurrence (P = 0.006). Median progression-free survival was significantly longer for NKD2-high patients than NKD2-low patients (49.1 vs.14.1 months, P &lt; 0.001). Accordingly, there was a significantly difference in terms of overall survival time between two groups (hazard ratio: 3.04; 95% confidence interval: 1.58–5.85, P &lt; 0.001). Multivariate regression suggested that NKD2 was independently prognostic factors in terms of progression-free survival (hazard ratio: 2.91; 95% confidence interval: 1.61–5.27, P &lt; 0.001) and overall survival (hazard ratio: 3.6; 95% confidence interval: 1.80–7.21, P &lt; 0.001). In vitro studies further demonstrated that NKD2 suppressed ovarian cancer cell proliferation, colony formation and cell migration. Conclusion NKD2 is a novel prognostic marker and could suppress tumor progression in ovarian cancer.

Background: This study aimed to evaluate the safety and efficacy of weekly paclitaxel and cisplatin chemotherapy (wTP) in patients with ovarian cancer who developed carboplatin hypersensitivity reaction (HSR). Methods: We retrospectively investigated 86 patients with ovarian, fallopian tube, and peritoneal carcinoma who developed carboplatin HSR during previous chemotherapy (carboplatin and paclitaxel) at our institution between 2011 and 2019. After premedication was administered, paclitaxel was administered over 1 h, followed by cisplatin over 1 h (paclitaxel 80 mg/m2; cisplatin 25 mg/m2; 1, 8, 15 day/4 weeks). We investigated the incidence of patients who successfully received wTP for at least one cycle, treatments compliance, progression-free survival (PFS), and overall survival (OS). Results: The median number of wTP administration cycles was 4 (Interquartile Range IQR, 3–7), 71 patients (83%) successfully received wTP, and 15 patients (17%) developed cisplatin HSR. The efficacy of treatment was as follows: 55 (64%) patients completed the scheduled wTP, 9 (10%) patients discontinued due to HSR to cisplatin within 6 cycles, 1 (1%) patient discontinued due to renal toxicity (grade 2) at the 6th cycle, and 21 (24%) patients discontinued due to progressive disease within 6 cycles. The median PFS and OS after administration of wTP were 10.9 months (95% CI: 7.7–17.7) and 25.9 months (95% CI: 19.0–50.2), respectively. Conclusions: wTP was safe and well-tolerated in patients who developed carboplatin HSR.
