The objective of this study is to compare progression-free survival (PFS) and overall survival (OS) of ovarian cancer patients treated with neoadjuvant chemotherapy and surgery to primary surgery and postoperative chemotherapy. Retrospective analysis from 1998 to 2003 of 116 patients with ovarian cancer was performed. Fifty women diagnosed by positive cytology received three cycles of carboplatin and paclitaxel. Thirty-six patients subsequently underwent cytoreductive surgery and completed three further cycles postoperatively. The OS and PFS were compared in 66 women treated with primary surgery and postoperative chemotherapy. A statistically significant difference was observed for OS (P= 0.03, HR = 1.85, CI = 1.06–3.23) and PFS (P= 0.04, HR = 1.61, CI = 1.03–2.53) favoring the primary surgery group. Due to the small numbers, age, grade, stage, pleural effusions, and histologic cell type were controlled for separately in the bivariate analyses. Controlling for stage made the results weaker. A matched subgroup survival analysis was performed on patients who had surgery following neoadjuvant chemotherapy. After matching for stage and grade and controlling age and pleural effusions (N= 28 matched pairs), there was no statistical difference for OS (P= 0.95, HR = 1.04, CI = 0.33–3.30) or PFS (P= 0.79, HR = 1.11, CI = 0.98–1.04). It is concluded that primary surgery should be considered in all patients. Neoadjuvant chemotherapy may be an alternative in a subset of women with the intent to also perform interval debulking.

ObjectiveThe role of lymphadenectomy in interval debulking surgery (IDS) performed after neoadjuvant chemotherapy (NACT) in advanced ovarian cancer remains unclear. We aimed to investigate the clinical significance of lymphadenectomy in IDS.MethodsWe retrospectively reviewed and analyzed the data of patients with advanced ovarian cancer who underwent NACT followed by IDS.ResultsIn 303 patients receiving NACT-IDS, lymphadenectomy was performed in 127 (41.9%) patients. One hundred and sixty-three (53.8%) patients achieved no gross residual disease (NGRD), and 69 (22.8%) had residual disease < 1 cm, whereas 71 (23.4%) had residual disease ≥ 1cm. No significant difference in progression-free survival (PFS) and overall survival (OS) was observed between the lymphadenectomy group and the no lymphadenectomy group in patients with NGRD, residual disease < 1 cm, and residual disease ≥ 1 cm, respectively. The proportions of pelvic, para-aortic and distant lymph node recurrence were 7.9% (10/127), 4.7% (6/127) and 5.5% (7/127) in the lymphadenectomy group, compared with 5.7% (10/176, P = 0.448), 4.5% (8/176, P = 0.942) and 5.1% (9/176, P = 0.878), respectively, in no lymphadenectomy group. Multivariate analysis identified residual disease ≥ 1 cm [hazard ratios (HR), 4.094; P = 0.008] and elevated CA125 levels after 3 cycles of adjuvant chemotherapy (HR, 2.883; P = 0.004) were negative predictors for OS.ConclusionLymphadenectomy may have no therapeutic value in patients with advanced ovarian cancer underwent NACT-IDS. Our findings may help to better the therapeutic strategy for advanced ovarian cancer. More clinical trials are warranted to further clarify the real role of lymphadenectomy in IDS.

5561 Background: The influence of germline BRCA1/2 mutations (gBRCAmt) on ovarian cancer patients (pts) long-term survival remains controversial. Methods: 228 pts with serous and endometrial ovarian cancer stage Ic-IV were enrolled in the retrospective study. Next-generation sequencing testing of BRCA1/2 in blood was employed. Progression-free survival (PFS), overall survival (OS) and time to platinum resistance (TPR) were analyzed. TPR was defined as time from first line chemotherapy to registration of platinum resistance relapse. Results: The rate of pathogenic gBRCAmt was defined in 29.4% (67/228) pts. There was no any significant difference between BRCA1/2 mutation carries and non-carries in both PFS (18.3 and 16.7 months, p = 0.27, HR 0.79, 95%CI 0.52-1.20) and OS (71.9 and 79.1 months, p = 0.69, HR 0.88, 95%CI 0.46-1.68). However, TPR was significantly longer in pts with gBRCAmt than in germline BRCA wild type (gBRCAwt) pts (51.4 and 34.4 months, p = 0.05, HR 0.60, 95% CI 0.36-0.98). Pts with gBRCAmt had poor prognosis after registration of platinum resistance. gBRCAwt pts had longer survival than gBRCAmt after platinum-resistance relapse: 33.7 and 16.9 months respectively (p = 0.05; HR 1.85, 95%CI 1.02-4.08). Conclusions: Our finding provided possible explanation of equal survival of pts with or without BRCA1/2 mutations. Long-term sensitivity to platinum-based chemotherapy allowed pts with gBRCA1/2mt to control the disease for a long period of time. However the non-platinum regimens had less efficacy in pts with gBRCAmt than gBRCAwt after platinum resistance.

Tumor Debulking

Primary surgery for advanced ovarian cancer has been the standard practice for more than 30 years. A survival benefit is principally seen in patients who have optimal cytoreduction with no or small-volume residual disease after surgery. In everyday clinical practice, many patients are not able to undergo optimal tumor debulking. Modern preoperative imaging and assessment can identify most of these patients. Through developments in platinum-based chemotherapy, a high proportion of patients can be expected to respond to primary (neoadjuvant) chemotherapy. A recent clinical trial has shown that the survival of patients with operable disease is not disadvantaged by neoadjuvant chemotherapy followed by surgery. Thus, complete tumor cytoreduction could be achieved in a greater percentage of patients, if primary chemotherapy is used in women in whom optimal primary surgery would be difficult. Furthermore, delayed surgery provides more knowledge about the biological behavior of the tumor, and this could be used to tailor treatment more effectively.

BackgroundPrimary cytoreductive surgery followed by chemotherapy has been considered standard management for patients with advanced ovarian cancer over decades. An alternative approach of interval debulking surgery following neoadjuvant chemotherapy was subsequently reported by two randomized phase III trials (EORTC‐GCG, CHORUS), which were criticized owing to important limitations, especially regarding the rate of complete resection.Primary ObjectiveTo clarify the optimal timing of surgical therapy in advanced ovarian cancer.Study HypothesisPrimary cytoreductive surgery is superior to interval cytoreductive surgery following neoadjuvant chemotherapy for overall survival in patients with advanced ovarian cancer.Trial DesignTRUST is an international open, randomized, controlled multi-center trial investigating overall survival after primary cytoreductive surgery versus neoadjuvant chemotherapy and subsequent interval cytoreductive surgery in patients with FIGO stage IIIB–IVB ovarian, tubal, and peritoneal carcinoma. To guarantee adequate surgical quality, participating centers need to fulfill specific quality assurance criteria (eg, ≥50% complete resection rate in upfront surgery for FIGO IIIB–IVB patients, ≥36 debulking-surgeries/year) and agree to independent audits by TRUST quality committee delegates. Patients in the primary cytoreductive surgery arm undergo surgery followed by 6 cycles of platinum-based chemotherapy, whereas patients in the interval cytoreductive surgery arm undergo 3 cycles of neoadjuvant chemotherapy after histologic confirmation of the disease, followed by interval cytoreductive surgery and subsequently, 3 cycles of platinum-based chemotherapy. The intention of surgery for both groups is complete tumor resection according to guideline recommendations.Major Inclusion/Exclusion CriteriaMajor inclusion criteria are suspected or histologically confirmed, newly diagnosed invasive epithelial ovarian cancer, fallopian tube carcinoma, or primary peritoneal carcinoma FIGO stage IIIB–IVB (IV only if resectable metastasis). Major exclusion criteria are non-epithelial ovarian malignancies and borderline tumors; prior chemotherapy for ovarian cancer; or abdominal/pelvic radiotherapy.Primary EndpointOverall survival.Sample Size772 patients.Estimated Dates for Completing Accrual and Presenting ResultsAccrual completion approximately mid-2019, results are expected after 5 years' follow-up in 2024.Trial RegistrationNCT02828618.

e17085 Background: Epithelial ovarian cancer is the second most common gynecologic malignancy and is characterized by the highest mortality of all gynecological cancers. Despite of initial response, platinum resistance develops and contributes to the poor outcome of advanced stage ovarian cancer patients. The aim of the study was to identify biomarkers helpful in predicting treatment response to platinum salts. Methods: Forty eight patients with advanced ovarian (stage II, III and IV) cancer were prospectively enrolled between 2014 and 2017. All patients underwent surgery followed by platinum-based chemotherapy. Serum reactive oxygen species parameters such as malondialdehyde, ceruloplasmine, and serum VEGF were measured before each cycle of chemotherapy. Results: Mean age at diagnostic was 51.3 +/- 8.1 years, (range 42 - 78). Median follow up was 39 months (range 12-56). Twenty tree percent were platinum resistance. Median progression free survival was 22 months and estimated median overall survival was 84 months, 77% of patients being alive at 3 years. VEGF levels were significantly higher in patients with platinum resistance disease (1210 pg/ml) compare to platinum sensitive (mean VEGF levels 945pg/ml, p = 0.0003). We used a ROC curve to estimate the sensitivity and specificity of VEGF as a predictor to platinum response and find out that the aria under the curve (AUC) was 0.874, p = 0.003, 95% CI 0.734-1 and cut-off value (80% sensibility, 80% specificity) was 1085pg/ml. Malondialdehyde levels were statistically significant higher in patients with platinum resistance disease (mean value 11.1 μmol/100 ml vs. 7.4 μmol/100 ml in platinum sensitive, p = 0.02. The ROC curve for malondialdehyde identify an aria under the curve of 0.818, p = 0.0001 and CI 95% (0.744-0.893) and a cut-off value of 7.74 μmol/100 ml to estimate with 81.3% sensitivity and 64% specificity platinum response validating this bio markers as predicting platinum response. For Ceruloplasmine AUC was 0.706, p = 0.0001, 95% CI (0.617,-0.796). Conclusions: Malondialdehyde, ceruloplasmine and VEGF can estimate with precision the resistance to platinum salts in advanced ovarian cancer patients.

Abstract Most advanced ovarian cancer patients experience recurrence and develop resistance to platinum-based agents. However, the diagnosis of platinum resistance based on platinum-free interval is not always accurate and timely. In this study, we employed laser ablation inductively coupled plasma mass spectrometry to visualize platinum distribution in the tissues at the time of interval debulking surgery following neoadjuvant chemotherapy. Twenty seven patients with advanced high grade serous ovarian cancer were enrolled. Two distinct patterns of platinum distribution were observed. Type A (n = 16): platinum accumulation at the adjacent stroma but little in the tumor; type B (n = 11): even distribution of platinum through tumor and adjacent stroma. Type A was significantly correlated with worse prognosis (P = 0.031). Patients classified in type A and treated with platinum-based adjuvant chemotherapy after operation were significantly shorter period of recurrence after last platinum-based chemotherapy (P = 0.020) and diagnosed with “platinum-resistant recurrence”. Treatment with non-platinum-based chemotherapy after operation could be effective for the patients who were classified in type A. Our data indicate that the platinum resistance can be predicted prior to recurrence with platinum distribution. Thus, we will be able to select more appropriate adjuvant chemotherapy, which may possibly lead to improve patient’s prognosis.

Objective: To explore the effect of bevacizumab combined with neoadjuvant chemotherapy in advanced ovarian cancer and the occurrence of adverse reactions. Methods: A total of 80 patients with advanced ovarian cancer, treated in Affiliated People’s Hospital of Inner Mongolia Medical University from June 2019 to December 2020, were randomly divided into two groups. In the chemotherapy group, 40 patients were treated with neoadjuvant chemotherapy, while in the combined group, another 40 patients were treated with bevacizumab combined with neoadjuvant chemotherapy. The therapeutic effects were compared at the end of the treatment cycle. Results: There was no significant difference in the levels of CA125, CEA, and VEGF between the two groups before treatment. However, after the treatment cycle, the levels of CA125, CEA, and VEGF in the combined group were significantly better than those in the chemotherapy group (P < 0.05). At the same time, the incidence of adverse reactions of the chemotherapy group was 67.50%, which was significantly higher than that of the combined group (35.00%; P < 0.05). Conclusion: Bevacizumab combined with neoadjuvant chemotherapy for patients with advanced ovarian cancer has significant curative effect. The combined therapy reduces the levels of tumor markers and inflammatory factors, improves patients’ quality of life, as well as reduces adverse reactions. It has high clinical promotion value.

The choice of treatment strategy in patients with stage IIIC‑IV ovarian cancer (OC) remains the subject of numerous discussions. The reason for this is the unsatisfactory results of randomized trials and the low frequency of primary complete debulking surgery in these studies. We conducted a retrospective analysis to evaluate the survival outcomes in patients with OC stage IIIC–IV (n=314) who underwent treatment between 1995 and 2017. The median progression free survival for primary surgery was 15.6 months, after interval debulking – 11.5 months (p=0.002, HR 0.61: 95 % CI 0.39–0.81). The primary cytoreduction significantly increased the median of overall survival by 19.6 months: from 38.0 months after interval debulking up to 57.6 months after primary cytoreduction (p=0.04, HR 0.64: 95 % CI 0.41–0.99). An increase in the number of optimal interval debulking does not lead to an improvement in the long-term results of treatment in the group of patients after neoadjuvant chemotherapy. Our analysis over the past 20 years has shown that improvement in treatment outcomes is only observed in the primary cytoreduction group due to an increase in the number of complete optimal cytoreductive surgery.
