Improve Patient Selection

Epithelial ovarian cancer remains a leading cause of death amongst all gynecologic cancers despite advances in surgical and medical therapy. Historically, patients with ovarian cancer underwent primary tumor reductive surgery followed by postoperative chemotherapy; however, neoadjuvant chemotherapy followed by interval tumor reductive surgery has gradually become an alternative approach for patients with advanced-stage ovarian cancer for whom primary tumor reductive surgery is not feasible. Decision-making about the use of these approaches has not been uniform. Hence, it is essential to identify patients who can benefit most from neoadjuvant chemotherapy followed by interval tumor reductive surgery. Several prospective and retrospective studies have proposed potential models to guide upfront decision-making for patients with advanced ovarian cancer. In this review, we summarize important decision-making models that can improve patient selection for personalized treatment. Models based on clinical factors (clinical parameters, radiology studies and laparoscopy scoring) and molecular markers (circulating and tumor-based) are useful, but laparoscopic staging is among the most informative diagnostic methods for upfront decision-making in patients medically fit for surgery. Further research is needed to explore more reliable models to determine personalized treatment for advanced epithelial ovarian cancer.

The Relationship

Chemoresistance is one of the main causes of treatment failure in advanced ovarian cancer (OC). In order to identify predictors of chemoresistance, 30 patients with ascitic form of OC, who received neoadjuvant chemotherapy (NACT) according to AP regimen, were examined. In the epithelial cells of ascites and in tumor tissue after NACT, expression of the VEGFa, ABCB1 and ERCC1 genes was assessed by PCR-RT. The effectiveness of NACT was assessed using the criteria of therapeutic pathomorphosis, survival - using the Kaplan-Meier criterion, the relationship of clinical and molecular parameters - using the Mann-Whitney criterion. Results. We established that in 43% of patients the response to NACT was absent (CRS1), the significant response (CRS2) was in 35% of cases, and the complete response (CRS3) was in 21% of cases. VEGFa expression was increased in ascites in 17% of cases, in tumor tissue - in 33% in the CRS1 group. In groups with CRS 2,3, overexpression of VEGFa in ascites was detected in 25% of cases, in tumor tissue in 37.5%. ABCB1 mRNA expression was increased after NACT in 50% of cases in the CRS1 group and in 25% of cases in the CRS 2,3 group. Thus, platinum-based NACT initiates an increase in the expression of VEGFa and ABCB1 in tumor tissue. We established that in case of high expression (ERCC + / VEGF + / ABCB1 +) in ascites, there is a statistically significant increase in relapse-free survival compared with the group with low or absent expression (p = 0.012). The overall survival rate was 41.8 months in patients with overexpression of the studied genes in the tissue of the primary tumor after NACT and 25.3 months in patients with low expression (p = 0.058). Conclusion. The levels of ERCC1, VEGFa and ABCB1 mRNA in ascitic cells before NACT and in the primary tumor after NACT according to the AP scheme can serve as a predictor of the effectiveness of this treatment in ascitic OC.

Introduction: Although weekly paclitaxel and carboplatin regimen is as effective as the standard method for treatment of advanced ovarian cancer, it has less frequently been used as neoadjuvant therapy. Objectives: To reduce the side effects of typical every three-week chemotherapy and increase progression-free survival (PFS) rate, this study aimed to evaluate the feasibility of using weekly paclitaxel as neoadjuvant therapy in patients with epithelial ovarian cancer. Patients and Methods: This pre-post clinical trial was conducted on 14 patients with stage IIIC (8 patients) and IV (6 patients) advanced ovarian carcinoma. All the patients received the three courses of treatment and then underwent interval debulking surgery. After the surgery, patients received three or five courses based on their stages. Every neoadjuvant chemotherapy course consisted of weekly paclitaxel (80 mg/m2 ) and carboplatin (AUC=6) every 3 weeks. After every 21 days of treatment course, the patients were evaluated to investigate their response to treatment and side effects. Patients were followed up for at least 6 months. Results: The mean (SD) age of the patients was 64±8 years. After three courses of neoadjuvant chemotherapy, one patient (7%) had a complete response and 13 patients (93%) had a partial response. During the treatment period, two patients (14%) developed anemia, one patient (7%) developed neutropenia, two patients (14%) developed thrombocytopenia, and six patients (43%) developed neuropathy. The median (interquartile range) of PFS was 13 months (9.5-16.25). Conclusion: The findings showed that a weekly paclitaxel and carboplatin regimen as neoadjuvant therapy could be effective in the treatment of advanced ovarian cancer. However, it is necessary to conduct multicenter studies with larger sample sizes. Trial registration: Registration of trial protocol has been approved in Iranian Registry of Clinical Trial (identifier: IRCT2017050333789N1; http://en.irct.ir/trial/25978)

BackgroundGrowing evidence supports the role of neoadjuvant chemotherapy in patients with advanced epithelial ovarian cancer. Currently, there is no shared histopathologic scoring system to assess pathologic response in the specimens obtained at interval surgery after neoadjuvant chemotherapy This review aims to summarize the literature on pathologic response, focusing on proposed scoring systems.MethodsThe systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, focusing on the definition of pathologic response, its prognostic value, possible predictors, and future implications. Eighteen manuscripts focusing on pathologic response in epithelial ovarian cancer were selected for analysis.ResultsOverall, eight histopathologic scoring systems to evaluate pathologic response have been proposed. There are currently no available markers (serum, radiological, genomic) to select which patients could achieve the highest benefit from neoadjuvant chemotherapy experiencing a complete pathologic response. A three-tier scoring system (CRS) based on omental assessment and which classifies the response to neoadjuvant chemotherapy has been validated in external cohorts of epithelial ovarian cancer. This scoring system demonstrated adequate interobserver reproducibility. Data is limited on the pathologic complete response rate changes according to chemotherapy regimen.ConclusionsA histopathologic scoring system endowed with prognostic value could be helpful in personalizing the treatment decision in patients with epithelial ovarian cancer.

The Impact

Background:We evaluated the impact of neoadjuvant chemotherapy (NC) relative to primary surgery (PS) to determine if there was a difference in the total time and number of chemotherapy cycles given in patients with advanced epithelial ovarian cancer.Methods:We identified 263 consecutive women meeting eligibility from 1993 to 2005 for this institutional review board-approved study. Eligible patients in this analysis were those women with advanced disease (stage IIIC-IV) in whom a maximal cytoreductive effort was planned either at PS or after NC. Time to start chemotherapy was defined as follows: (1) NC group: confirmation of diagnosis through biopsy, cytological diagnosis from ascites, and pleural effusion; (2) PS group: confirmation of diagnosis from the date of surgery that confirmed the diagnosis of epithelial ovarian cancer. Total chemotherapy cycles: (1) NC group: NC chemotherapy cycles plus postoperative cycles; (2) PS group: chemotherapy after primary tumor debulking surgery. Clinical information evaluated included chemotherapy type, chemotherapy cycle number, total time to administer frontline chemotherapy, and survival.Results:Median chemotherapy cycles were greater in the NC group compared with the PS group (9 [range, 4-30] vs 6 [range, 3-19];P< 0.01). The PS group was also more likely to undergo chemotherapy regimens involving platinum and taxane treatment compared with the NC group (79% vs 65%;P= 0.017). Total time undergoing primary chemotherapy from initial diagnosis was greater in the NC group compared with PS (223 vs 151 days;P< 0.01). No significant difference was observed in overall survival and progression-free survival in the 2 groups.Conclusions:In patients with advanced ovarian cancer, NC followed by abdominal hysterectomy is associated with improved perioperative outcomes including optimal cytoreduction, decreased blood loss, and decreased inpatient hospitalization. In this cohort, NC was also associated with prolonged chemotherapy treatment intervals and increased chemotherapy cycles without improvement in survival.

e17044 Background: Epithelial ovarian cancer is the second most common gynecological malignancy among Indian women. Primary debulking surgery remains the standard of care in advanced operable ovarian cancer patients, but is associated with morbidity. Neoadjuvant chemotherapy followed by delayed primary cytoreductive surgery maybe a better treatment strategy in advanced ovarian cancer. We present our experience of neoadjuvant chemotherapy in advanced ovarian cancer with special emphasis on treatment outcomes. Methods: A retrospective analysis of advanced epithelial ovarian carcinoma (Stage IIIc and IV) patients treated at the Department of Surgical Oncology at King George’s Medical University, Lucknow between 2012 and 2017 was done. Results: A total of 151 patients with advanced ovarian carcinoma were treated during this period. Median age at diagnosis was 46 years. Among these patients, 137 underwent surgery, of which 59.1% were optimally cytoreduced. Papillary serous adenocarcinoma was the most common histological subtype (76.1%). Recurrence was seen in 79.3% patients, with a median time to recurrence 17 months (range 6.5 - 39 months). They were managed with second line chemotherapy and surgery. Median overall survival in this study for optimally cytoreduced stage III patients was 39 months and 18 months for optimally cytoreduced stage IV patients. Median progression free survival for stage III was 12 months and stage IV was 6 months. Conclusions: Neoadjuvant chemotherapy facilitates surgery in advanced ovarian cancer and helps in assessing chemotherapy responsiveness. It provides an opportunity to modify systemic treatment if there no response to therapy or disease progression.

Systematic Lymph Node Dissection

Recent robust data allow for omitting lymph node dissection for patients with advanced epithelial ovarian cancer (EOC) and without any suspicion of lymph node metastases, without compromising recurrence-free survival (RFS), nor overall survival (OS), in the setting of primary surgical treatment. Evidence supporting the same postulate for patients undergoing complete cytoreductive surgery after neoadjuvant chemotherapy (NACT) is lacking. Throughout a systematic literature review, the aim of our study was to evaluate the impact of lymph node dissection in patients undergoing surgery for advanced-stage EOC after NACT. A total of 1094 patients, included in six retrospective series, underwent either systematic, selective or no lymph node dissection. Only one study reveals a positive effect of lymphadenectomy on OS, and two on RFS. The four remaining series fail to demonstrate any beneficial effect on survival, neither for RFS nor OS. All of them highlight the higher peri- and post-operative complication rate associated with systematic lymph node dissection. Despite heterogeneity in the design of the studies included, there seems to be a trend showing no improvement on OS for systematic lymph node dissection in node negative patients. A well-conducted prospective trial is mandatory to evaluate this matter.

ObjectivesNeoadjuvant chemotherapy may be considered for women with epithelial ovarian cancer who have poor performance status or a disease burden not amenable to primary cytoreductive surgery. Overlap exists between indications for neoadjuvant chemotherapy and known risk factors for venous thromboembolism, including impaired mobility, increasing age, and advanced malignancy. The objective of this study was to determine the rate of venous thromboembolism among women receiving neoadjuvant chemotherapy for epithelial ovarian cancer.MethodsA multi-institutional, observational study of patients receiving neoadjuvant chemotherapy for primary epithelial ovarian, fallopian tube, or peritoneal cancer was conducted. Primary outcome was rate of venous thromboembolism during neoadjuvant chemotherapy. Secondary outcomes included rates of venous thromboembolism at other stages of treatment (diagnosis, following interval debulking surgery, during adjuvant chemotherapy, or during treatment for recurrence) and associations between occurrence of venous thromboembolism during neoadjuvant chemotherapy, subject characteristics, and interval debulking outcomes. Venous thromboembolism was defined as deep vein thrombosis in the upper or lower extremities or in association with peripherally inserted central catheters or ports, pulmonary embolism, or concurrent deep vein thrombosis and pulmonary embolism. Both symptomatic and asymptomatic venous thromboembolism were reported.ResultsA total of 230 patients receiving neoadjuvant chemotherapy were included; 63 (27%) patients overall experienced a venous thromboembolism. The primary outcome of venous thromboembolism during neoadjuvant chemotherapy occurred in 16 (7.7%) patients. Of the remaining venous thromboembolism events, 22 were at diagnosis (9.6%), six post-operatively (3%), five during adjuvant chemotherapy (3%), and 14 during treatment for recurrence (12%). Patients experiencing a venous thromboembolism during neoadjuvant chemotherapy had a longer mean time to interval debulking and were less likely to undergo optimal cytoreduction (50% vs 80.2%, p=0.02).ConclusionsPatients with advanced ovarian cancer are at high risk for venous thromboembolism while receiving neoadjuvant chemotherapy. Consideration of thromboprophylaxis may be warranted.
