5536 Background: Standard guidelines recommend adjuvant chemotherapy for stage I clear cell ovarian cancer (CCOC), despite data demonstrating excellent outcomes. Since 2012, the BC Cancer provincial treatment guidelines for surgically staged stage IA/B and IC1 (defined by intraoperative rupture only) CCOC has been to offer observation only. We reviewed the clinical outcomes of stage I CCOC patients since policy implementation. Methods: A retrospective, population-based cohort study of all stage I CCOC patients operated on between April 2012 and December 2017 was conducted. Patient, tumor, surgical and clinical outcome data were collected. Survival analysis was conducted using Kaplan-Meier methods. Results: 78 patients with stage I disease were identified (see Table). Among stage IC1 patients, 9 received adjuvant therapy despite provincial policy, 6 of which were due to sharp dissection. 40 patients with stages IA/B and IC1, who underwent post-operative observation, were included in the analysis. Median duration of follow-up was 36 months. Median age at diagnosis was 55 years and >50% patients had a Charlson Comorbidity Index of 0 (N= 26) and an Eastern Cooperative Oncology Group performance status of 0 (N=28) prior to diagnosis. Lymph node dissection was not performed in 20 patients. All 16 cases tested immunohistochemically for mismatch repair were intact, and 2 of 6 cases with tumour genomic sequencing had an AURKA aberration. There were 4 recurrences (10%), 3 of which were metastatic. 5-year disease-free survival is 90%, and 5-year overall survival is 95% for stage IA/B and 90% for stage IC1 (p=0.645). In comparison, 5-year overall survival for stage IC2 (surface involvement) and IC1 with sharp dissection (all received chemotherapy) is 82% and for stage IC3 (positive washings) is 23% (p<0.001). Conclusions: Outcomes of patients with stage I A/B and C1 CCOC remain excellent. Adjuvant therapy can be safely omitted, with low recurrence rates and survival over 90% at 5 years. Consideration of disease substage is valuable in predicting the clinical outcomes of stage I CCOC. [Table: see text]

5069 Background: To determine if extent of lymphadenectomy affects the survival of women with stage I ovarian cancer. Methods: Demographic and clinico-pathologic information were obtained from the Surveillance, Epidemiology and End Results Program from 1988–2001 and analyzed using Kaplan-Meier methods and Cox proportional hazards regression. Results: Of the 6,686 women diagnosed with stage I ovarian cancer, 4,092 (61.2%) had stage IA, 392 (5.9%) had stage IB, 1,840 (27.5%) had stage IC, and 362 (5.4%) had unspecified stage I disease. The median age was 53 (range: 1–99). 5,625 (84.1%) were White, 388 (5.8%) Black, 488 (7.3%) Asian, and 185 (2.8%) were Other. All patients underwent primary surgery; of which, 3,824 women had no nodes, 1,533 had <10 nodes, and 1,329 had ≥10 nodes resected. Of the patients who underwent a lymphadenectomy, the median number of nodes resected was 9 (range: 1–84). The extent of lymphadenectomy (0, <10, and ≥10 nodes) increased the survival of patients with stage IC disease from 72.8%, 86.7%, to 90.1% (p < 0.0001), but not in those with stage IA (p = 0.07) or stage IB (p = 0.04) disease. In patients with non-clear cell epithelial carcinoma, the extent of lymphadenectomy was associated with improved 5-year disease-specific survivals of 85.6%, 93.3%, and 93.5%, respectively (p < 0.0001). However, the benefit associated with an extensive lymphadenectomy was not evident in clear cell (p = 0.09), sarcoma (p = 0.33), germ cell (p = 0.55), or sex cord stromal tumors of the ovary (p = 0.99). Similarly, patients with grade 3 disease had an improved survival associated with the extent of lymph node resection, 74.4%, 87.5%, to 90.5% (p < 0.0001), but not in those with grade 1 (p = 0.18) or grade 2 (p = 0.27) disease. In multivariate analysis, a more extensive lymphadenectomy remained significant as an independent prognostic factor for improved survival after adjusting for all other independent prognostic factors including age, surgery, histology, stage, and grade. Conclusions: Our findings suggest that the extent of lymphadenectomy was associated with an improvement in the survival of women with stage IC ovarian cancer. No significant financial relationships to disclose.

e17105 Background: Intraperitoneal (IP) chemotherapy has been shown to prolong overall survival in optimally debulked stage III ovarian cancer in randomized trials. In British Columbia, we extrapolated this benefit of IP chemotherapy to early stage HGSC patients for the last 10 years, as these patients are optimally debulked at surgery but still have a high rate of recurrence. We conducted a retrospective study of clinical outcomes associated with IP/IV chemotherapy compared to IV chemotherapy for optimally debulked stage I HGSC cases. Methods: This was a retrospective cohort study of women with stages IA-IC HGSC who had primary surgery between 2007-2015, and received either IV or IP/IV chemotherapy post-operatively. We compared progression-free survival (PFS) and overall survival (OS) outcomes between these 2 groups. Kaplan-Meier method evaluated chemotherapy delivery route with progression free survival (PFS) and overall survival (OS), using the statistical program R. Results: We identified 99 patients; 80 (81%) received IV chemotherapy and 19 (19%) received IP/IV chemotherapy. Among IP/IV cohort, 2/19 (11%) discontinued IP therapy during treatment due to abdominal pain at IP port site or hypersensitivity reaction to IV paclitaxel. 5-year PFS was 88.4% (74.5-100%) and 69.7% (58.7-82.7%) among the IP/IV and IV cohorts, respectively (p = 0.549). There was a trend for higher 5-year OS for the IP/IV group; however, this did not reach statistical significance (100% vs. 71.4%; p = 0.182). Conclusions: In our study, IP/IV chemotherapy for stage I HGSC patients was associated with a trend for higher 5-year PFS and OS compared to IV chemotherapy. This observation warrants further prospective investigation.

Purpose The objective of this study was to assess clinical outcomes and fertility in patients treated conservatively for unilateral stage I invasive epithelial ovarian cancer (EOC). Patients and Methods A multi-institutional retrospective investigation was undertaken to identify patients with unilateral stage I EOC treated with fertility-sparing surgery. Favorable histology was defined as grade 1 or grade 2 adenocarcinoma, excluding clear cell histology. Results A total of 211 patients (stage IA, n = 126; stage IC, n = 85) were identified from 30 institutions. Median duration of follow-up was 78 months. Five-year overall survival and recurrence-free survival were 100% and 97.8% for stage IA and favorable histology (n = 108), 100% and 100% for stage IA and clear cell histology (n = 15), 100% and 33.3% for stage IA and grade 3 (n = 3), 96.9% and 92.1% for stage IC and favorable histology (n = 67), 93.3% and 66.0% for stage IC and clear cell histology (n = 15), and 66.7% and 66.7% for stage IC and grade 3 (n = 3). Forty-five (53.6%) of 84 patients who were nulliparous at fertility-sparing surgery and married at the time of investigation gave birth to 56 healthy children. Conclusion Our data confirm that fertility-sparing surgery is a safe treatment for stage IA patients with favorable histology and suggest that stage IA patients with clear cell histology and stage IC patients with favorable histology can be candidates for fertility-sparing surgery followed by adjuvant chemotherapy.

ObjectivesTo assess the effect of complete surgical staging and adjuvant chemotherapy on survival in stage I, low grade endometrioid ovarian cancer.MethodsThis retrospective study was conducted at two cancer centers from July 2001 to December 2019. Inclusion criteria were all stage I, grade 1 and 2 endometrioid ovarian cancer patients. Patients with mixed histology, concurrent endometrial cancer, neoadjuvant chemotherapy, and patients who did not undergo follow-up at our centers were excluded. Clinical, pathologic, recurrence, and follow-up data were collected. Cox proportional hazard model evaluated predictive factors. Recurrence-free survival and overall survival were calculated using the Kaplan-Meier method.ResultsThere were 131 eligible stage I patients: 83 patients (63.4%) were stage IA, 5 (3.8%) were stage IB, and 43 (32.8%) were stage IC, with 80 patients (61.1%) having grade 1 and 51 (38.9%) patients having grade 2 disease. Complete lymphadenectomy was performed in 34 patients (26.0%), whereas 97 patients (74.0%) had either partial (n=22, 16.8%) or no (n=75, 57.2%) lymphadenectomy. Thirty patients (22.9%) received adjuvant chemotherapy. Median follow-up was 51.5 (95% CI 44.3 to 57.2) months. Five-year recurrence-free survival was 88.0% (95% CI 81.6% to 94.9%) and 5 year overall survival was 95.1% (95% CI 90.5% to 99.9%). In a multivariable analysis, only grade 2 histology had a significantly higher recurrence rate (HR 3.42, 95% CI 1.03 to 11.38; p=0.04). There was no difference in recurrence-free survival (p=0.57) and overall survival (p=0.30) in patients with complete lymphadenectomy. In stage IA/IB, grade 2 there was no benefit of adjuvant chemotherapy (p=0.19), and in stage IA/IB, low grade without complete surgical staging there was no benefit of adjuvant chemotherapy (p=0.16). Twelve patients (9.2%) had recurrence; 3 (25%) were salvageable at recurrence and are alive with no disease.ConclusionsPatients with stage I, low grade endometrioid ovarian cancer have a favorable prognosis, and adjuvant chemotherapy and staging lymphadenectomy did not improve survival.

ObjectivesNeoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) may be a valuable treatment option in advanced ovarian cancer when primary cytoreduction is not feasible. However, a consensus on the ideal number of NACT cycles is still lacking. In the present investigation, we aimed to evaluate how number of cycles of NACT influenced patients' outcomes.MethodsData of consecutive patients undergoing NACT and IDS were retrospectively reviewed in 4 Italian centers, and survival outcomes were evaluated.ResultsOverall, 193 patients were included. Cycles of NACT were 3, 4, and at least 5 in 77 (40%), 74 (38%), and 43 (22%) patients, respectively. Patients undergoing 3 cycles experienced a similar disease-free survival (hazard ratio [HR], 1.12; 95% confidence interval [CI], 0.89–1.65; P = 0.20) but an improved overall survival (HR, 1.64; 95% CI, 1.05–2.4; P = 0.02) in comparison to patients receiving at least 4 cycles. Five-year overall survival was 46% and 31% for patients having 3 and at least 4 cycles. Ten-year overall survival was 26% and 18% for patients having 3 and at least 4 cycles (HR, 1.70; 95% CI, 1.13–2.55; P = 0.009). Using multivariate analysis, we observed that only Eastern Cooperative Oncology Group performance status correlated with overall survival (HR, 1.76; 95% CI, 1.2–2.49; P = 0.001). In addition, a trend toward worse overall survival was observed for patients with residual disease at IDS (HR, 1.29; 95% CI, 0.98–1.70; P = 0.06) and patients receiving at least 4 cycles (HR, 1.76; 95% CI, 0.95–3.22; P = 0.06).ConclusionOur data underline the potential implication of number of cycles of NACT before IDS. Further prospective studies are warranted to assess this correlation.

Abstract Background Many studies have confirmed that the systemic inflammatory response and hypercoagulable state of the patient are related to the occurrence and development of various tumors, including pancreatic cancer. The aim of this research was to combine blood inflammatory factors and D-dimer into a new prognostic scoring system.Methods We conducted a retrospective cohort study of 73 patients with metastatic pancreatic cancer between January 2015 and December 2018 at our institution. To identify the prognostic predictors, circulating inflammatory cells and D-dimer were analyzed.Results Univariate analysis showed that the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), CA19-9, Eastern Cooperative Oncology Group performance status (ECOG PS) score and D-dimer levels were significantly associated with overall survival in patients with metastatic pancreatic cancer. Multivariate analysis suggested that only the NLR (p<0.026) and D-dimer level (p<0.012) were independent prognostic predictors. Then, we combined the NLR and D-dimer level to divide the cohort into three “NLRD” groups: “NLRD0”=NLR≤3.38 and D-dimer≤1.47, “NLRD1”=either NLR>3.38 or D-dimer>1.47, “NLRD2”=NLR>3.38 and D-dimer>1.47. Finally, we found that the NLRD2 group had the worst survival, with a median overall survival (OS) of 2 months (95%CI=1.450-2.550), while the NLRD0 group had the best outcome, with a median OS of 7 months (95%CI=5.897-8.121).Conclusions The scoring system combining the blood NLR with D-dimer levels provides important prognostic information for risk stratification in patients with metastatic pancreatic cancer and may help us identify patients who have a poor prognosis so that clinicians can develop personalized treatment strategies for these patients.

5547 Background: Sertoli-Leydig cell tumors (SLCT) are rare ovarian sex cord-stromal tumors which occur primarily in adolescents and young adults and are associated with DICER1 pathogenic variants. Methods: Informed consent for participation in the International PPB/ DICER1 or OTST Registry was obtained. When available, pathology was centrally reviewed. Staging was evaluated by Registry review using the International Federation of Gynecology and Obstetrics (FIGO) classification system. Results: Eighty-three patients with stage I SLCT were enrolled. Median age at diagnosis was 15 (range 1-60) years. Most (57/83) patients had germline DICER1 testing; 35/57 (61%) had germline pathogenic variants. Fifty-six patients had Ia and 27 had Ic SLCT. The distribution of patients receiving chemo based on histology and stage is displayed in Table. One patient with poorly differentiated stage Ia SLCT with sarcomatous elements and no chemo at diagnosis recurred 6 months after surgery and died of disease. Three patients with local diagnosis of stage Ia SLCT, with data unavailable for Registry confirmation of stage, developed a subsequent SLCT 33 to 74 months after diagnosis; of these, 2 died, and 1 remains in treatment for recurrence. Available records and molecular testing in these 3 cases have not provided a distinction between recurrent and metachronous disease. Excluding the latter 3 patients, 3-year overall survival was 97.3% for stage Ia SLCT. Six patients with stage Ic SLCT recurred (Stage Ic1=5 and Stage Ic2=1) with a median time to recurrence of 25 (range 3-53) months. In stage Ic1, 18% (2/11) recurred after upfront chemo compared to 33% (3/9) after surgery alone. Of the 5 patients with stage Ic1 disease that recurred, 4 had intermediate and 1 had poorly differentiated SLCT. One patient had sarcomatous elements and 2 received upfront chemo. Two of the 5 patients are alive, neither received upfront chemo. One patient with poorly differentiated stage Ic2 SLCT with sarcomatous elements and no upfront chemo recurred and died of disease. Three-year event free and overall survival were 86.9 and 88.6% for stage Ic SLCT. Four patients had metachronous SLCT in the contralateral ovary confirmed by clinical review or somatic testing at a median time from diagnosis of 33 (range 28-104) months. All 4 have germline pathogenic variants and no evidence of disease at last follow-up. Conclusions: Individuals with early stage SLCT generally fare well, however, ongoing surveillance for recurrence and metachronous disease is indicated. Novel therapies are needed to address recurrent SLCT.[Table: see text]

IntroductionTo evaluate clinical outcomes for patients with localized recurrent ovarian cancer treated with salvage radiotherapy.MethodsIn a retrospective single institutional analysis, we identified 40 patients who received salvage radiotherapy for localized ovarian cancer recurrence from January 1995 to June 2011. Recurrent disease was categorized as: pelvic peritoneal (45%, 18), extraperitoneal/nodal (35%, 14), or vaginal (20%, eight). Actuarial disease-free and overall survival estimates were calculated by Kaplan–Meier and prognostic factors evaluated by the Cox proportional hazards model.ResultsMedian follow-up was 42 months. Median patient age was 54 years (range, 27–78). Histologic subtypes were: serous (58%, 23), endometrioid (15%, six), clear cell (13%, five), mucinous (8%, three), and other (8%, three). At the time of salvage radiotherapy, surgical cytoreduction was performed in 60% (24) and 68% (27) had platinum-sensitive disease. Most patients (63%, 25) received salvage radiotherapy at the time of first recurrence. Relapse after salvage radiotherapy occurred in 29 patients at a median time of 16 months and was outside the radiotherapy field in 62%. 18 At 3 years, disease-free and overall survival rates were 18% and 80%, respectively. On multivariate analysis, non-serous histology (hazards ratio 0.3, 95% CI 0.1–0.7) and platinum-sensitivity (hazards ratio 0.2, 95% CI 0.1–0.5) were associated with lower relapse risk. Platinum-sensitivity was also associated with overall survival (hazards ratio 0.4, 95% CI 0.1–1.0). Four patients (10%) were long-term survivors without recurrence 5 years after salvage radiotherapy. Of the five patients with clear cell histology, none experienced relapse at the time of last follow-up.DiscussionPatients with non-serous and/or platinum-sensitive ovarian cancer had the greatest benefit from salvage radiotherapy for localized recurrent disease. Although relapse was common, radiotherapy prolonged recurrence for > 1 year in most patients and four were long-term survivors.

ObjectiveTo evaluate trends in use of radiation therapy and its impact on overall survival in low- and high-grade stage I endometrioid endometrial carcinoma.MethodsPatients with stage I endometrial cancer who underwent hysterectomy from 2004 to 2013 were identified through the National Cancer Database and classified as: stage IA G1/2, stage IA G3, stage IB G1/2, and stage IB G3. Trends in use of vaginal brachytherapy and external beam radiation therapy were assessed. Overall survival was measured from surgery and estimated using the Kaplan-Meier method. The effect of radiation therapy on overall survival was assessed within each stage/grade group using Cox proportional hazards analysis in propensity-matched treatment groups.ResultsA total of 132 393 patients met inclusion criteria, and 81% of patients had stage IA and 19% had stage IB endometrial cancer. Adjuvant therapy was administered in 18% of patients: 52% received vaginal brachytherapy, 30% external beam radiation therapy, and 18% chemotherapy ±radiation therapy. External beam radiation therapy use decreased from 9% in 2004 to 4% in 2012, while vaginal brachytherapy use increased from 8% to 14%. Stage IA G1/2 patients did not benefit from either external beam radiation therapy or vaginal brachytherapy, while administration of vaginal brachytherapy improved overall survival in stage IB G1/2 compared with no treatment (p<0.0001). In stage IB G1/2 and stage IA G3, vaginal brachytherapy was superior to external beam radiation therapy (p=0.0004 and p=0.004, respectively). Stage IB G3 patients had improved overall survival with either vaginal brachytherapy or external beam radiation therapy versus no treatment but no difference in overall survival was seen between vaginal brachytherapy and external beam radiation therapy (p=0.94).ConclusionsThe delivery of adjuvant radiation therapy in patients with stage IA G1/2 endometrial carcinoma is not associated with improvement in overall survival. Patients with stage IB G1/2 and G3 as well as stage IA G3 are shown to benefit from improved overall survival when adjuvant radiation therapy is administered. These findings demonstrate potential opportunities to reduce both overtreatment and undertreatment in stage I endometrial cancer patients.
