e17099 Background: Studies demonstrate racial disparity in ovarian cancer survival though survival differences seem to be mitigated when patients receive similar care. We sought to identify whether racial disparity exists in the use of NAC or PDS for women with ovarian cancer. Methods: After IRB approval, all patients with epithelial ovarian cancer who received primary treatment at our institution from 2005-2016 were identified from our tumor registry. Charts were retrospectively reviewed for clinicopathologic and survival data. Categorical variables were compared with chi-squared and continuous variables with the student t-test. Kaplan-Meier was used to compare survival probabilities. Results: 302 evaluable patients were identified. 240 (79%) patients underwent PDS and 62 (21%) received NAC. Older patients, black patients, and those with stage III/IV disease were more likely to receive NAC. In a multivariate analysis controlling for stage and age, black race remained associated with NAC [OR 3.25 (95% CI 1.41-7.47), p < 0.01]. In a subgroup of advanced disease, stage III patients (n = 138) were more likely than stage IV patients (n = 52) to undergo PDS (78% v 44%, p < 0.01) and black patients were more likely than others to present with stage IV disease (39% v 22%, p = 0.01). NAC was utilized more frequently (48% v 24%, p < 0.01) in black patients compared with all other races. In the advanced stage subgroup analysis, patients that underwent PDS had a longer PFS than those that received NAC [HR 2.21 (95% CI 1.26-3.89), p = 0.01]. Conclusions: Racial disparity exists in the selection of PDS compared with NAC for patients with ovarian cancer and this disparity persists when controlling for stage and age. The choice of NAC or PDS may result in survival disparity. Further investigation is needed to examine other reasons, such as medical co-morbidities and disease distribution, for racial disparity in management. [Table: see text]

e17037 Background: Two important developments in ovarian cancer have occurred over the last decade: i) EORTC 55971 and CHORUS trials reporting neoadjuvant chemotherapy as a management strategy in advanced disease and ii) recognition of fallopian tubes as the origin of many ovarian cancers. This study examines how these have impacted on care and registry data. Methods: The National Cancer Registry and Analysis Service (NCRAS) database identified women registered with ovarian, peritoneal and fallopian tube carcinomas during 2004-15. Treatment was defined as surgical intervention or chemotherapy starting within 6 months of diagnosis. Women were grouped into: Neoadjuvant chemotherapy, Primary surgery, Chemotherapy only, Surgery only or No record of therapy. Groups were analysed by year, FIGO stage and age. Results: 66,768 women were registered with an invasive carcinoma. Disease stage was not recorded in 44%. Of the remaining (n = 36,779) 32.1% stage I/II and 67.9% had stage III/IV disease. Of the 66,768 cases, 12.5 % had Neoadjuvant chemotherapy, 28.7% Primary surgery, 15.2% Surgery only, 19.7% Chemotherapy only and 23.2% No recorded therapy. Chemotherapy only was commonest at 36% in Stage IV, whereas primary surgery was in Stage III disease at 38%. No therapy was recorded in 11% and 25% of stage III and IV disease respectively. Neoadjuvant chemotherapy use trebled with time: comparing the rate in 2004-6 to 2013-15, there was an increase from7.7% to 21.7% ( p< 0.001). Those diagnosed with primary peritoneal cancer were significantly more likely ( p< 0.001) to have neoadjuvant chemotherapy compared to other groups. Cancers of the primary peritoneal and fallopian tube make up an increasing proportion of cases from 6% in 2004 to 13% in 2015. Conclusions: This is the largest reported study assessing trends in primary therapy and cases of ovarian, peritoneal and fallopian tube cancers during a time of novel developments. Neoadjuvant chemotherapy is becoming embedded in clinical practice. The reporting and analysis of ovarian cancer should include peritoneal and fallopian tube for consistent categorisation.

5514 Background: In the Phase III PAOLA-1/ENGOT-ov25 trial (NCT02477644), the addition of maintenance olaparib to bev in pts with newly diagnosed advanced high-grade ovarian cancer (HGOC) resulted in a significant PFS benefit, particularly in HRD-positive (HRD+) pts (hazard ratio [HR] 0.33; 95% CI 0.25–0.45) (Ray-Coquard et al. NEJM 2019). We explored efficacy in HRD+ pts by disease stage. Methods: Pts with newly diagnosed, FIGO stage III–IV HGOC in response after platinum-based chemotherapy + bev received bev (15 mg/kg q3w for 15 months [mo]) + either olaparib (300 mg bid for 24 mo) or placebo (pbo). This exploratory analysis evaluated PFS (data cut-off [DCO]: Mar 22 2019) and PFS2 (DCO: Mar 22 2020) in HRD+ pts (tumor BRCA1/ BRCA2 mutation [tBRCAm] or genomic instability score [Myriad myChoice HRD Plus] ≥42) by FIGO stage. Results: 387/806 randomized pts (48%) were HRD+; 272/387 (70%) had stage III disease and 115/387 (30%) had stage IV disease. 153 (56%) HRD+ stage III pts and 61 (53%) HRD+ stage IV pts had a tBRCAm. Among HRD+ stage III pts, 172 (63%) had upfront surgery (51/172 [30%] had residual disease) and 90 (33%) had interval surgery (19/90 [21%] had residual disease); 52 (45%) HRD+ stage IV pts had upfront surgery (34/52 [65%] had residual disease) and 55 (48%) had interval surgery (18/55 [33%] had residual disease). Median follow-up for PFS and PFS2 was respectively 24.8 and 37.2 mo in HRD+ stage III pts and 24.0 and 37.0 mo in HRD+ stage IV pts. Median PFS, PFS2 and HRs are in the Table. Among HRD+ stage III pts, 36-mo PFS2 (olaparib + bev vs pbo + bev) was 74% vs 60%; among HRD+ stage IV pts, 53% vs 30%. Among HRD+ stage III pts with no residual disease after upfront surgery, HR (95% CI) for PFS was 0.15 (0.07–0.30) and for PFS2 was 0.22 (0.06–0.67). Among HRD+ stage III pts with residual disease after upfront surgery or who received neoadjuvant chemotherapy, or HRD+ stage IV pts, HR (95% CI) for PFS was 0.38 (0.27–0.53) and PFS2 was 0.68 (0.46–1.03). Conclusions: In the PAOLA-1 study, maintenance olaparib + bev provided a PFS and PFS2 benefit over pbo + bev in HRD+ pts, irrespective of FIGO stage and residual disease after upfront surgery.

e18081 Background: Receipt of guideline care improves survival for women with ovarian cancer yet care may vary by race. We assessed the receipt of guideline care and cancer deaths by race for women with incident ovarian cancer. Methods: This retrospective cohort analysis used the National Cancer Institute’s Patterns of Care data for black and white women diagnosed with all stages of ovarian cancer in 2002 and 2011 (n = 5356) with follow-up through 12/31/14. Data included patient characteristics, type of surgery and chemotherapy, and provider factors. Multivariate logistic regression was used to create the standardized percentages (predictive margins) of women receiving guideline treatment by race group. Cox proportional hazards models were used to assess the unadjusted and adjusted risk of ovarian cancer death by race. Results: At diagnosis, for black women, 35.6% had Stage III and 37.2% had Stage IV disease compared with 44.1% Stage III and 24.2% Stage IV for white women. More black women had surgery in large teaching hospitals (47.6%) than white women (39.7%) but use of gynecologic oncologists (GO) was similar for black women and white women- (62.1% vs 58.8%). In regression models, the standardized percent of black women receiving guideline care was significantly lower than for white women (29.2% vs 38.5%). The unadjusted hazards ratio (HR) for death was significantly higher in black women (HR = 1.32) yet after controlling for patient and provider factors and receipt of guideline care, black women did not have a significantly higher risk of death (HR = 1.08). Conclusions: Rates of guideline care are very low for all women with ovarian cancer, significantly more so for black patients. Low use of guideline care among black women cannot be explained by provider factors as a large percent of black women consulted a GO or received care in large teaching hospitals. Research is needed to address how to increase guideline care among black patients as we found that race was not associated with the risk of death when guideline care was included as a factor in multivariate survival models.

9032 Background: Consolidation checkpoint inhibitor therapy (CPI) for up to 1 year following chemoradiation (CRT) is a current standard of care for pts with inoperable stage III NSCLC. However, some pts are not able to complete 1 year of CPI due to immune-related adverse events (irAES). In multiple retrospective studies, pts with stage IV NSCLC treated with CPI who experience irAEs generally receive fewer cycles of CPI without a significant detrimental effect on efficacy. The association between irAEs and outcomes with consolidation CPI after CRT has never been reported. Here we report the association between irAEs and efficacy outcomes from the HCRN LUN 14-179, a single-arm phase II trial of consolidation pembrolizumab following concurrent CRT in pts with unresectable stage III NSCLC. Methods: After completion of CRT eligible pts with stage III NSCLC without PD received pembrolizumab 200 mg IV q 3 wks for up to 1 yr. Demographics, disease characteristics, and number of cycles of pembrolizumab received were reported in pts who had any grade irAEs (except pneumonitis which included grade >2 only) [Group A] and those without irAEs (except grade 1 pneumonitis) [Group B]. Chi-square test (or Fisher's Exact test) were used for comparisons for categorical variables and Wilcoxon test for continuous variables. The Kaplan-Meier method was used to analyze time to metastatic disease (TMDD), PFS, and OS. A log-rank test was used to compare groups. Results: 92 eligible pts for efficacy analysis were enrolled from March 2015 to November 2016. 4 yr OS estimate for all pts is 46.2%. Any grade irAEs (except grade I pneumonitis) (n = 37 pts) included pneumonitis (18.5%), colitis (3.3%), increased creatinine (5.4%), elevated transaminases (3.3%), hyperthyroidism (7.6%), hypothyroidism (13.0%). Grade ≥ 2 irAEs (n = 32 pts) included pneumonitis (18.5%), hypothyroidism (10.8%), and colitis (3.3%). Group A/B: male (21/38), female (16/17), current or former smoker (35/52), stage IIIA (20/35), stage IIIB (17/20), non-squamous (21/30), squamous (16/25). Median number of pembrolizumab cycles received in Group A/B pts were 9 vs 15 (p = 0.0942) respectively. 4 yr efficacy endpoints in Groups A/B were TMDD 35.3% vs 41.3% (p = 0.83), PFS 27.8% vs 28.7% (p = 0.97), OS 43.5% vs 47.9% (p = 0.99), respectively. Conclusions: Despite receiving fewer cycles of consolidation pembrolizumab, pts who experienced any grade irAEs (excluding grade 1 pneumonitis) did not have significantly reduced efficacy outcomes.

Fifty-six patients with ovarian cancer (three stage IC, nine stage II, 33 stage III and II stage IV) were treated with carboplatin 350 mg m−2 i.v. day 1 and chlorambucil orally 0.15 mg kgm−1 days 1–7 inclusive, repeated every 28 days for eight courses. The regimen was well tolerated and was virtually free of nephro- and neurotoxicity. Grade III or IV hematology toxicity occurred in 18 patients but only 31 or 330 courses administered were delayed. Of 40 assessable patients eight achieved a clinical/radiologic complete response and 17 a clinical/radiologic partial response. Actuarial survival at 50 months was 65% for stage II patients, 27% for stage III patients and no stage IV patients survived beyond 20 months. Forty-two per cent of patients with residual disease less 2 cm survived 50 months, compared with 44% of patients with moderate volume (2–5 cm) residual disease and 6% of patients with bulk residual disease. This is an active, well tolerated regimen. However, only patients with small volume residual disease have a significant chance of prolonged survival.

ObjectiveWe sought to describe a large, international cohort of patients diagnosed with primary mucinous ovarian carcinoma (PMOC) across 3 tertiary medical centers to evaluate differences in patient characteristics, surgical/adjuvant treatment strategies, and oncologic outcomes.MethodsThis was a retrospective review spanning 1976–2014. All tumors were centrally reviewed by an expert gynecologic pathologist. Each center used a combination of clinical and histologic criteria to confirm a PMOC diagnosis. Data were abstracted from medical records, and a deidentified dataset was compiled and processed at a single institution. Appropriate statistical tests were performed.ResultsTwo hundred twenty-two patients with PMOC were identified; all had undergone primary surgery. Disease stage distribution was as follows: stage I, 163 patients (74%); stage II, 8 (4%); stage III, 40 (18%); and stage IV, 10 (5%). Ninety-nine (45%) of 219 patients underwent lymphadenectomy; 41 (19%) of 215 underwent fertility-preserving surgery. Of the 145 patients (65%) with available treatment data, 68 (47%) had received chemotherapy—55 (81%) a gynecologic regimen and 13 (19%) a gastrointestinal regimen. The 5-year progression-free survival (PFS) rates were 80% (95% confidence interval [CI], 73%–85%) for patients with stage I to II disease and 17% (95% CI, 8%–29%) for those with stage III to IV disease. The 5-year PFS rate was 73% (95% CI, 50%–86%) for patients who underwent fertility-preserving surgery.ConclusionsMost patients (74%) presented with stage I disease. Nearly 50% were treated with adjuvant chemotherapy using various regimens across institutions. The PFS outcomes were favorable for those with early-stage disease and lower but acceptable for those who underwent fertility preservation.

e18719 Background: Clinical pathways have been introduced as tools to optimize cancer care delivery, but evidence of their value in the real world is limited. This retrospective study was performed to assess treatment patterns and clinical outcomes in patients with non-small cell lung cancer (NSCLC) before and after pathway implementation at Tennessee Oncology (TO). Methods: Chart data were abstracted for patients (≥18 years) diagnosed with Stage I-IV NSCLC who initiated first-line (1L) systemic treatment at a TO clinic and had follow-up for ³6 months or until death. Patients were divided into two cohorts: pre-pathways (treatment initiation 2014–2015) and post-pathways (treatment initiation 2016–2018). Patient characteristics, treatment patterns, and outcomes were described and compared across cohorts. An exploratory study endpoint was the evaluation of outcomes based on disease stage at diagnosis. Results: Among 501 patients (251 pre-pathways and 250 post-pathways), most had advanced or metastatic NSCLC at diagnosis (Stage III: 40%; Stage IV: 42%). Chemotherapy comprised almost all 1L systemic therapy used pre-pathways (Stage I/II: 100%; Stage III: 96%; Stage IV: 83%). Post-pathways, chemotherapy remained the most common 1L therapy in patients with Stage I/II (89%) and Stage III (72%) disease, but among patients with Stage IV disease, use of chemotherapy decreased (47%) and immuno-oncology (IO) therapy alone or in combination became common (45%). Median duration of 1L therapy was longer post-pathways in patients with Stage III (2.1 months vs 1.4 months pre-pathways; P < 0.01) and Stage IV disease (3.3 months vs 2.3 months pre-pathways; P < 0.01) but did not differ among Stage I/II patients. Median progression-free survival was significantly longer post-pathways in patients with Stage IV disease (7.0 months vs 4.2 months pre-pathways; P < 0.05), but not in other disease-stage subgroups. Median overall survival increased non-significantly post-pathways for all disease stage subgroups (Stage I/II: 26 months vs 20 months pre-pathways; Stage III: 26 months vs 20 months; Stage IV: 10 months vs 9 months). For each disease stage, rates of severe adverse events were similar between cohorts. Conclusions: While outcomes for patients diagnosed with Stage III/IV NSCLC were generally improved following the implementation of clinical pathways, this change coincided with a dramatic shift in available treatment options. Improvements post-pathways were mainly observed in patients diagnosed with advanced disease. Thus, differences in outcomes between pre-pathways and post-pathways cohorts in our study are more likely attributable to other evolving practices in cancer care, particularly the availability of newer, more effective treatments such as IO therapy as part of standard practice, than implementation of the clinical pathways.

Objective We speculate that genetic racial disparity exists in fetal life and can be detected by modern computerized cardiotocography (cCTG). Methods This is a retrospective study comparing the results of the cCTG of pregnant patients at 37–42 weeks according to the parental ethnicity (black versus white). A cCTG was performed to analyze the variables of fetal heart rate (FHR). The cCTG variables analyzed were: percentage of signal loss; number of contractions; basal FHR; number of accelerations; number of decelerations; length of high variation episodes; short-term variability (STV); total trace duration time; and number of fetal active movements. Non-stress test (NST) parameters in the two groups were compared using the Mann-Whitney test for continuous data, and the Chi-square test for categorical variables. Results We found a significantly lower number of active fetal movements (p = 0.007) and longer periods of low variation (p = 0.047) in the cCTG of black patients when compared with white patients. Conclusions In conclusion, identifying the factors responsible for the variance in the objective analysis of CTG results is important to improve the outcomes of patients. Our study lends further evidence as to the importance of ethnicity in clinical cCTG interpretation.

ObjectiveWe described progression-free survival and overall survival in patients with primary mucinous ovarian cancer receiving adjuvant gynecologic versus gastrointestinal chemotherapy regimens.MethodsWe identified all primary mucinous ovarian cancer patients receiving adjuvant gynecologic or gastrointestinal chemotherapy regimens at a single institution from 1994 to 2016. Gynecologic pathologists using strict pathologic/clinical criteria determined diagnosis. Adjuvant therapy was coded as gynecologic or gastrointestinal based on standard agents and schedules. Clinical/pathologic/treatment characteristics were recorded. Wilcoxon rank-sum test was used for continuous variables, and Fisher’s exact test for categorical variables. Progression-free and overall survival were calculated using the Kaplan-Meier method, applying landmark analysis.ResultsOf 62 patients identified, 21 received adjuvant chemotherapy: 12 gynecologic, 9 gastrointestinal. Median age (in years) at diagnosis: 58 (range 25–68) gynecologic cohort, 38 (range 32–68) gastrointestinal cohort (p=0.13). Median body mass index at first post-operative visit: 25 kg/m2(range 18–31) gynecologic cohort, 23 kg/m2(range 18–31) gastrointestinal cohort (p=0.23). History of smoking: 6/12 (50%) gynecologic cohort, 3/9 (33%) gastrointestinal cohort (p=0.66). Stage distribution in gynecologic and gastrointestinal cohorts, respectively: stage I: 9/12 (75%) and 3/9 (33%); stage II: 2/12 (17%) and 1/9 (11%); stage III: 1/12 (8%) and 5/9 (56%) (p=0.06). Grade distribution in gynecologic and gastrointestinal cohorts, respectively: grade 1: 8/12 (67%) and 1/9 (13%); grade 2/3: 4/12 (33%) and 7/9 (88%) (p=0.03). Three-year progression-free survival: 90.9% (95% CI 50.8% to 98.7 %) gynecologic, 53.3% (95% CI 17.7% to 79.6%) gastrointestinal. Three-year overall survival: 90.9% (95% CI 50.8% to 98.7%) gynecologic, 76.2% (95% CI 33.2% to 93.5%) gastrointestinal.ConclusionOngoing international collaborative research may further define associations between chemotherapy regimens and survival.
