Quo Vadis

e15568 Background: The efficacy of PDS for advanced ovarian cancer has recently been challenged by data suggesting equivalent clinical outcomes for neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS). The strongest known predictor of prolonged survival in either group is the ability to achieve complete resection (CR) to no residual disease. PDS that results in a CR is associated with the longest overall survival of any sequence of treatment. The aim of this study was to determine what type of surgical approach is required to successfully perform PDS. Methods: All women with newly diagnosed stage IIIC epithelial ovarian carcinoma treated at our institution from 2000 to 2010 were identified. Pathology was prospectively reviewed by a faculty gynecologic pathologist. Treatment planning was discussed and documented at our weekly multidisciplinary tumor board conference. Data was retrospectively extracted from computerized medical records. Results: 344 (86%) of 401 women underwent PDS. Optimal debulking was achieved in 278 patients (81%): 35% had CR while 46% had 0.1-1.0 cm residual disease. 56 stage IIIC pts (19%) had a suboptimal surgical outcome with ≥ 1.0 cm. Compared to those having a CR, patients with 0.1-1.0 cm residual were more likely to require splenectomy (17 v 5%; P = 0.002) and transverse colectomy (19 v 10%; P = 0.042), with comparable rates of rectosigmoid resection (41 v 39%; P = 0.712) and en bloc pelvic resection including total peritonectomy (26 v 30%; P = 0.050). Patients undergoing CR were more likely to have diaphragmatic surgery (31 v 20; P = 0.068) and lymphadenectomy (67 v 33%; P < 0.001). Conclusions: PDS is the preferred treatment of stage IIIC epithelial ovarian cancer at high-volume centers demonstrating >75% rates of optimal cytoreduction. Tumor biology may lead to the need for more aggressive upper abdominal procedures in patients with 0.1-1.0 residual. Diaphragm resection, stripping or ablation is more often required in order to achieve CR. Since subclinical macroscopic nodal metastases are often present, lymphadenectomy is also frequently performed to ensure that all possible disease has been resected.

The Impact

Primary debulking surgery (PDS) followed by platinum-based chemotherapy has been the cornerstone of treatment for advanced ovarian cancer for decades. Primary debulking surgery has been repeatedly identified as one of the key factors in improving survival in patients with advanced ovarian cancer, especially when minimal or no residual disease is left behind. Achieving these results sometimes requires extensive abdominal and pelvic surgical procedures and consultation with other surgical teams. Some clinicians who propose a primary chemotherapy approach reported an increased likelihood of leaving no macroscopic disease after surgery and improved patient-reported outcomes and quality-of-life (QOL) measures. Given the ongoing debate regarding the relative benefit of PDS versus neoadjuvant chemotherapy (NACT), tumor biology may aid in patient selection for each approach. Neoadjuvant chemotherapy offers the opportunity for in vivo chemosensitivity testing. Studies are needed to determine the best way to evaluate the impact of NACT in each individual patient with advanced ovarian cancer. Indeed, the biggest utility of NACT may be in research, where this approach provides the opportunity for the investigation of predictive markers, mechanisms of resistance, and a forum to test novel therapies.

5540 Background: Primary debulking surgery (PDS) has been considered the standard of treatment in advanced ovarian cancer, while neoadjuvant chemotherapy, three cycles followed by interval debulking (ID) surgery, is a valid treatment alternative for patients with non-resectable disease. This study aimed to show the efficacy and safety of six cycles of neoadjuvant chemotherapy (N-CT) followed by cytoreduction, a single institution experience. Methods: Aretrospective analysis was performed of all patients (pts) with advanced ovarian cancer treated with platinum based N-CT, between January/2004 and February/2012. Results: 97 pts underwent N-CT in our institution; 78.1% and 18.8% the patients had extensive stage IIIC or IV disease at diagnosis, respectively. Median age 60 years (36 – 82). Histologic types: serous 84.5%, adenocarcinoma not specified 11.3%, endometrioide 1.0%. A median of six cycles of chemotherapy were performed. Patients did not received chemotherapy after debulking surgery. During the treatment 31.4% had grade 3/4 toxicity, the most commonly observed toxicities were hematologic toxicities and nausea, four (4.1%) patients died during chemotherapy due to disease progression. After N-CT 24.7% achieved clinical complete response, 57.7% partial response and 12.4% disease progression. From this cohort 63.1% underwent a complete resection of all macroscopic and microscopic disease (R0). Median length of hospital stay and postoperative ICU stay was 5 and 0.8 days respectively, surgical complications were not common however five (7.1%) patients needed second surgery due to operatory complications and 19 pts (27.1%) needed blood transfusion after debulking. With a median follow up of 21.8 months (0.5-139.7), median overall survival and chemotherapy-free interval were 57,7 and 9,5 months, respectively. Conclusions: Six cycles of neoadjuvant carboplatin and paclitaxel is safe, effective and does not increase perioperative and postoperative complications for patients with stage IIIC-IV not candidates for optimal/R0 PDS. The overall survival of this cohort is higher than those treated with interval debulking surgery.

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 &lt; 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 &lt; 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.

16032 Background: The aim of this study was to evaluate the prognostic impact of histological response at the time of interval debulking surgery (IDS) in patients treated with neoadjuvant chemotherapy (NACT) for unresectable advanced-stage ovarian cancer (ASOC). Methods: A retrospective study was conducted in our institution to select cases fulfilling 3 following inclusion criteria: 1. Patients with unresectable (evaluated in most of them with initial surgery + biopsies) ASOC. All patients had residual disease > 2 cm after such initial surgery; 2. At least 3 courses of platinum + paclitaxel NACT; 3. Patients undergoing after NACT an IDS with absence of macroscopic residual disease at the end of the debulking surgery. IDS was followed by post-operative chemotherapy. Patients were classified into 3 groups according to the histological response (in the peritoneum & nodes) after NACT: group 1: no residual disease in peritoneum; group 2: persistent residual disease but with histological signs of chemoactivity (marked histological changes) and group 3: persistence of at least 1 site with no changes in the tumor (persistence of very active cells). Survival was compared between these 3 groups. Results: Fifty-eight patients treated between 1997 and 2004 fulfilled inclusion criteria (49 had stage IIIC and 9 stage IV disease). Respectively 47 & 11 patients received 3–4 or 5–6 courses of chemotherapy before IDS. Respectively 11, 11 and 36 patients were in groups 1, 2 & 3. The median time of follow-up was 41 months. Three-year overall survival in groups 1, 2 & 3 was respectively: 81%, 39% and 62% (no statistical difference). Three- year event-free survival in groups 1, 2 & 3 was respectively: 46%, 18% and 19% (p=.04 between group 1 versus 2+3). Conclusions: These results suggest that the degree of histological response have a limited impact on the survival of patients when complete debulking surgery is achieved at IDS. The degree of tumor cell viability after initial chemotherapy is not a reliable marker for modifying chemotherapy after debulking surgery in such patients. No significant financial relationships to disclose.

Purpose In 2010, a randomized clinical trial demonstrated noninferior survival for patients with advanced ovarian cancer who were treated with neoadjuvant chemotherapy (NACT) compared with primary cytoreductive surgery (PCS). We examined the use and effectiveness of NACT in clinical practice. Patients and Methods A multi-institutional observational study of 1,538 women with stages IIIC to IV ovarian cancer who were treated at six National Cancer Institute–designated cancer centers. We examined NACT use in patients who were diagnosed between 2003 and 2012 (N = 1,538) and compared overall survival (OS), morbidity, and postoperative residual disease in a propensity-score matched sample of patients (N = 594). Results NACT use increased from 16% during 2003 to 2010 to 34% during 2011 to 2012 in stage IIIC disease ( Ptrend < .001), and from 41% to 62% in stage IV disease ( Ptrend < .001). Adoption of NACT varied by institution, from 8% to 30% for stage IIIC disease (P < .001) and from 27% to 61% ( P = .007) for stage IV disease during this time period. In the matched sample, NACT was associated with shorter OS in stage IIIC disease (median OS: 33 v 43 months; hazard ratio [HR], 1.40; 95% CI, 1.11 to 1.77) compared with PCS, but not stage IV disease (median OS: 31 v 36 months; HR, 1.16; 95% CI, 0.89 to 1.52). Patients with stages IIIC and IV disease who received NACT were less likely to have ≥ 1 cm postoperative residual disease, an intensive care unit admission, or a rehospitalization (all P ≤ .04) compared with those who received PCS treatment. However, among women with stage IIIC disease who achieved microscopic or ≤ 1 cm postoperative residual disease, NACT was associated with decreased OS (HR, 1.49; 95% CI, 1.01 to 2.18; P = .04). Conclusion Use of NACT increased significantly between 2003 and 2012. In this observational study, PCS was associated with increased survival in stage IIIC, but not stage IV disease. Future studies should prospectively consider the efficacy of NACT by extent of residual disease in unselected patients.
