Introduction Patients with urothelial carcinoma (uc) have a poor prognosis after progression on first-line cisplatinbased chemotherapy. Real-world data about second-line cytotoxic therapies are limited. We sought to characterize patients with metastatic uc who receive more than 1 line of systemic therapy and to describe their treatments and outcomes.Methods Using BC Cancer’s pharmacy database, we identified patients with documented metastatic uc who had received more than 1 line of systemic therapy. A retrospective chart review was then performed to collect clinicopathologic, treatment, and outcomes data.Results The 51 included patients, of whom 42 were men (82%), had a median age of 65 years (range: 38–81 years). Sites of metastasis included lymph nodes (n = 30), bone (n = 7), lung (n = 9), and peritoneum (n = 2). Second-line chemotherapy regimens included gemcitabine–cisplatin [gc (n = 14)], paclitaxel (n = 24), docetaxel (n = 12), and an oral topoisomerase i inhibitor (n = 1). Median time to progression (ttp) and overall survival (os) were 2.0 and 6.83 months respectively. Compared with patients who received a different agent, patients who had experienced a prior response to first-line gc and who were re-challenged with second-line gc had a better median ttp (11.0 months vs. 6.0 months, p = 0.02) and survived longer (4.0 months vs. 1.0 months, p = 0.02). No differences in os between non-gc regimens were evident.Conclusions In patients with metastatic uc, overall outcomes remain poor, but compared with patients receiving other agents, the subgroup of patients re-challenged with second-line gc demonstrated improved ttp. Conventional chemotherapy regimens provide only modest benefits in the second-line setting and have largely been replaced with immunotherapy.

Objective: This study aimed to provide real-world data on the multidisciplinary management of metastatic penile squamous-cell carcinoma (mpSCC) patients and their survival outcomes, particularly those who receive best supportive care (BSC). Methods: A retrospective analysis of 1720 patients, managed via a supra-regional penile-specialist multidisciplinary team was conducted between January 2006 and May 2020. Results: A total of 101 patients (median age 63 years; interquartile range 56–72 years; 73% ECOG 0/1) were included. Of these, 32% (32/101) had previously received adjuvant chemotherapy prior to metastatic recurrence, 58% (59/101) received chemotherapy and 42% (42/101) received BSC. Further, 17% (17/101) received second-line systemic therapy, and 3% (3/101) received third-line systemic therapy. For first-line systemic-therapy, there was a 46% (27/59) clinical benefit rate (CBR), with 9% (5/59) complete response, 15% (9/59) partial response and 22% (13/59) stable disease. Patients receiving second-line therapy ( n=17) had a 29% (5/17) CBR. Median progression-free survival for first- and second-line treatment was 3.2 and 2.2 months, respectively. Median overall survival (mOS) for all patients was 6.2 months. mOS for first-line chemotherapy, second-line chemotherapy and BSC patients was 7.2, 4.5 and 2.0 months, respectively. Conclusions: First-line platinum-based chemotherapy is associated with notable response rates in mpSCC patients. Agents with better response rates are needed urgently potentially in combination with platinum-based chemotherapy. Level of evidence: Level 2b.

e21197 Background: Presence of leptomeningeal metastases (LM) in NSCLC is indicative of aggressive disease and the incidence is as high as 9%-16% in the EGFR mutant subgroup. Traditionally, these patients had a dismal outcome with WBRT and intrathecal chemotherapy. Osimertinib crosses the blood brain barrier and is efficacious in the second line setting, as seen in BLOOM trial (LM ORR of 62%) and AURA program (LM ORR 55%). Osimertinib has also demonstrated CNS efficacy in the first line (FLAURA trial). This study is a retrospective review of cases with LM treated with osimertinib, and their response outcomes. Methods: 16 patients of EGFR mutant NSCLC developed LM at some point in their disease course and were treated with osimertinib. Clinical features and response outcomes were retrieved from medical record archives. Descriptive statistics were done using SPSS v23 software. LM PFS was defined as the time between 1st dose of osimertinib and date of progression in LM. LM OS was defined as the time between the first dose of osimertinib to the date of last follow up/death. ORR was defined as the percentage of cases showing CR/PR to osimertinib. Results: Median age was 61 years (range: 33-79) with 9 males and 7 females. Del19 mutations were seen in 9 patients and L858R in 7 patients. Only one patient was given WBRT prior to TKI. 6 patients with LM at diagnosis were given 1st line osimertinib. 3 (50%) progressed in LM and 3 (50%) showed partial response. Median LM PFS and median LM OS was not reached. ORR for osimertinib in the first line was 83.3%. 10 patients developed LM later in the course of the disease and median time to onset of LM was 12.47 months. Median LM PFS for osimertinib was 7.9 months (95% CI:3.2-8.3). Median LM OS was 8.2 months (95% CI: 2.6-19.8 months). ORR for osimertinib in the later line was 60%. Conclusions: This early experience reveals superior efficacy of osimertinib in LM with an excellent LM ORR in the first line setting and concordant results with second line BLOOM Study. Despite the small numbers in this study, this report becomes clinically relevant owing to the rarity of LM occurrence and paucity of available data. Efficacy of osimertinib in EGFR treatment-naive patients with LM requires further investigation and a larger prospective trial with a longer follow up may help confirm our preliminary findings.

4535 Background: Treatment of advanced urothelial carcinoma (mUC) has improved following approvals of PD-1/PD-L1 inhibitors. Platinum chemotherapy remains the standard-of-care in the first-line (1L). Cisplatin (Cis) regimens are accepted to be superior to carboplatin (Carbo) regimens for patients (pts) who are Cis-eligible. We sought to evaluate if differences in efficacy of 1L Cis vs. Carbo have meaningful impact on overall survival (OS) in the era of second-line (2L) immunotherapy (IO). Methods: We conducted a retrospective, observational cohort study to compare OS for pts treated with 1L Cis or Carbo combined with gemcitabine (Gem) followed by 2L IO using patient-level data from the nationwide Flatiron Health electronic health record (EHR)-derived de-identified database. Pts included were diagnosed with mUC between 9/1/2015 and 9/15/2020. 2L IO was defined as single-agent atezolizumab, avelumab, durvalumab, nivolumab, or pembrolizumab. OS was calculated from start of 1L and 2L therapy and compared using Kaplan-Meier curves. Time to 2L IO was calculated from start of 1L to start of IO. Adjusted OS was calculated using multivariable Cox regression models, adjusting for age, gender, race, ECOG performance status, primary site, prior cystectomy, smoking status, and year of diagnosis. Results: A total of 1882 pts were included, 924 (49.1%) received Gem/Cis and 958 (50.9%) received Gem/Carbo in 1L. A similar percentage of pts did not receive any 2L therapy following Gem/Cis (46.4%) or Gem/Carbo (46.0%). Our analysis focused on the 780 pts (41.4%) who received 2L IO—381 after Gem/Cis and 399 after Gem/Carbo. Median follow-up time for the group was 35 months (mo). Pts in the Gem/Cis cohort were younger, had better performance status and lower incidence of upper tract disease (Table). OS from start of 1L therapy was numerically longer in pts who received Gem/Cis compared to Gem/Carbo on unadjusted (median 18.0 v 16.2 mo, p = 0.06) and adjusted analyses (HR = 0.83, 95% CI 0.69-1.00, p = 0.055) but neither result was statistically significant. Time to 2L IO was longer for pts receiving Gem/Cis (6.5 mo) vs Gem/Carbo (5.5 mo, p = 0.008). Survival time on 2L IO did not differ significantly by 1L regimen (Gem/Cis 8.0 mo vs Gem/Carbo 8.2 mo p = 0.36). Conclusions: Real world data suggests that in pts with mUC who are able to receive second-line IO, the choice of first-line platinum chemotherapy may not provide a distinguishable OS benefit. Despite methodologic limitations of this data, a greater focus in discussions with patients on toxicity associated with cisplatin vs carboplatin may be warranted.[Table: see text]

e13010 Background: Based on the results reported in Emilia trial population, current guidelines consider TDM-1 the standard second-line therapy for HER2 positive metastatic breast cancer (MBC) patients. Despite that, there are no prospective studies supporting the efficacy of TDM-1 following trastuzumab (T) + pertuzumab (P) and taxane first-line treatment. Currently, only real-world data have investigated this sequence with controversial results Methods: We performed a meta-analysis of the available real world data to determine the efficacy of TDM-1 after first-line TP in HER2 positive MBC patients. We used a random-effect model to find differences in the rate of 1-year progression free survival (PFS) between TP pre-treated population and the phase III Emilia trial (T pre-treated population). Results: Seven studies were eligible, in three of them data were from sub-group population analysis. The meta-analysis showed a combined 1-years PFS risk difference for TDM-1 efficacy after TP in second or more lines of -0.122, with lower and upper limits of -0.253 and 0.010, respectively (p=0.07) , with low heterogeneity among studies (I2 < 0.0001, p =0.836). Considering the four studies on TDM-1 in second-line setting, 1-years PFS risk was -0.034 (95% CI -0.207 – 0,139; p=0.701) (I2 < 0.0001, p =0.91). Conclusions: Results from the meta-analysis show that the efficacy of TDM-1 after TP double-block seems to be similar to the previously reported in Emilia trial. In the second line setting, available data are not mature enough to confirm TDM-1 efficacy in TP pre-treated population. Currently, TP pretreated patients should receive TDM-1 as indicated in the guidelines.

e16623 Background: The management of aHCC has evolved dramatically in recent years, with new agents like immunotherapy receiving regulatory approval. As we begin incorporating these drugs into routine clinical practice, data on real-world sequencing of therapies and clinical outcomes are needed. Methods: We utilised the DISCOVERYAI platform, a virtual machine containing de-identified patient electronic health records to review HCC patients treated at the National University Health System, Singapore from January 2015 to December 2019. We then identified those who received systemic therapy and correlated their clinical outcomes. Results: In total, 395 HCC patients were identified; 75 received surgery, 174 received loco-regional therapy and 102 referred for consideration of systemic therapy. Of those considered for systemic therapy, median age was 65 years (range 23-87); 88% male (n = 90); hepatitis B/hepatitis C/non-hepatitis, 41(40.2%)/ 10(9.8%)/ 51(50.0%). 75.5% (n = 77) of them received systemic therapy with a TKI and/or immunotherapy. 39% (n = 30) of these received second-line treatment. Child-Pugh score at start of treatment was A5/A6/B7/B8, 38(49.3%)/ 32(41.6%)/ 5(6.5%)/ 2(2.6%) respectively. In the first-line, 66% (n = 51) received TKI and 34% (n = 26) received immunotherapy. Amongst those treated with first-line TKI, 45% (n = 23) received second-line therapy; 65% (n = 15) immunotherapy, 35% (n = 8) another TKI. Of those treated with first-line immunotherapy, 27% (n = 7) received second-line TKI. At a median follow-up of 35 months, first-line median progression-free survival (mPFS) for TKI vs immunotherapy was 3.7 vs 3.1 months (HR 0.73; 95% CI, 0.40-1.33; p = 0.31). mPFS for second-line immunotherapy vs TKI was 4.0 vs 2.9 months (HR 0.43; 95% CI, 0.19-0.96; p = 0.04). When comparing sequencing of therapies, the combined first and second mPFS for TKI-immunotherapy/TKI-TKI/immunotherapy-TKI is 9.5/7.6/7.6 months respectively (log-rank test, p = 0.71). Those patients that received both immunotherapy and TKI had significantly higher overall survival (OS) compared to those receiving only immunotherapy or only TKI or none (mOS NR vs 10.1 vs 13.2 vs 4.7 months; p < 0.001). Conclusions: TKI remains an important pillar of treatment in aHCC in the era of immunotherapy. While immunotherapy provides long durable responses and benefit in a minority of patients, the majority appear to benefit from TKI. Biomarker studies are needed to discern treatment algorithms for aHCC.

e19131 Background: The platinum doublet is standard first-line therapy in advanced NSCLC. Over the past decade, well-tolerated second-line therapies have been approved, including erlotinib and pemetrexed. We hypothesize that the introduction of less-toxic chemotherapy has increased treatment of advanced NSCLC, resulting in improved survival. Methods: The BC Cancer Agency provides cancer care to a population of 4.5 million. A retrospective review was conducted of all referred stage IIIB/IV patients in four 1-yr time cohorts; C1 baseline (1998) and 6 months after the provincial approval of C2 docetaxel (2001), C3 erlotinib (2006) and C4 pemetrexed (2007). Results: 2,623 patients were referred and 720 had systemic therapy. Characteristics: M/F 55%/45%, median age 67 (33-101), ECOG <=1/>=2/unknown 33%/56%/11%, never/former/current/unknown smoker 9%/35%/36%/20%, squam/nonsquam/NOS 18%/41%/41%. More patients received first-line chemotherapy over time; 16%, 23%, 34%, 33% C1-4 respectively. In C1 to C4 uptake of second line (21%, 27%, 38%, 55%) and third line (10%, 10% 14%, 18%) increased. In C1 the most common first-line doublet was cis/vino (70%) and in C4, cis/gem (45%). Second-line doce was frequently used in C2 (51%) but usage decreased in C4 to 7% vs. erlo 50% and pem 26%. In the >=70 group (n=1,118), first-line usage increased from C1 9% to C4 19% and second-line in the C2 (doce) 4% to C4 (erlo+pem avail) 56%. The increased use of systemic therapy was associated with improved survival in all patients: C1 4.56 m vs C4 4.98 m (p=0.004) and treated patients; C1 9.48 m vs C4 12.07 m (p=0.014) and the >= 70 group; C1 9.7 m vs C4 12.5 m (p=0.07). Conclusions: This population-based data set represents the trend of treatments over time in a large geographical area, including community and tertiary care cancer treatment sites. The introduction of less-toxic systemic therapy for advanced NSCLC resulted in an increased proportion of patients treated with first-line chemotherapy and an even greater increase in second-/third-line treatment. This trend was particularly evident in the elderly. Associated with this was a significant improvement in overall survival for all subsets.

AbstractColorectal cancer is the second leading cause of cancer-related death worldwide. For metastatic colorectal cancer (mCRC) patients, it is recommended, as first-line treatment, chemotherapy (CT) based on doublet cytotoxic combinations of fluorouracil, leucovorin, and irinotecan (FOLFIRI) and fluorouracil, leucovorin, and oxaliplatin (FOLFOX). In addition to CT, biological (targeted agents) are indicated in the first-line treatment, unless contraindicated. In this context, most of mCRC patients are likely to progress and to change from first line to second line treatment when they develop resistance to first-line treatment options. It is in this second line setting where Aflibercept offers an alternative and effective therapeutic option, thought its specific mechanism of action for different patient’s profile: RAS mutant, RAS wild-type (wt), BRAF mutant, potentially resectable and elderly patients. In this paper, a panel of experienced oncologists specialized in the management of mCRC experts have reviewed and selected scientific evidence focused on Aflibercept as an alternative treatment.

e13020 Background: Cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) in combination with an aromatase inhibitor (AI) has emerged as the standard first line treatment in patients with hormone receptor positive, human epidermal growth factor receptor-2 (HER-2) negative metastatic breast cancer (MBC). In this analysis, we describe population-based outcomes for first-line treatment with a CDK4/6i combined with an AI. Methods: All patients who were prescribed CDK4/6i + AI from January 2016 through June 2019 in a large Canadian province were included. Descriptive statistics were used to summarize patient demographics, tumor and treatment characteristics. Survival distributions were estimated using the Kaplan-Meier method. Multivariate analysis (MVA) using a Cox proportional hazards model was constructed to examine associations between potentially prognostic clinical variables and progression free survival (PFS). Results: A total of 316 patients were included. Median age was 61 years (interquartile range, 53-70 years), 82% were postmenopausal women, 39% had de novo MBC, and 48% had non-visceral disease. Palbociclib was prescribed in 94% of patients and the remaining patients received ribociclib. The CDK4/6i was dose-reduced upfront or during treatment in 47%. While 70% of the patients discontinued treatment due to progression, 30% stopped due to toxicity/patient preference/physician recommendation. With a median follow-up of 28.1 months, the median PFS was 37.9 months (95% CI, 26.7-NR). In the MVA, PR-negative tumour (HR, 2.37; 95% CI, 1.45-3.88; P = 0.001) and dose reduction of the CDK4/6i (HR, 1.51; 95% CI, 1.06-2.16; P = 0.022) predicted worse PFS. Median overall survival (OS) was not reached. The 30-month and 36-month OS rates were 74% and 68%, respectively. Of patients who progressed (n = 131), 89% received second-line treatment (chemotherapy in 46%, single agent hormonal therapy in 35%, hormonal therapy plus a targeted agent in 15%, and other in 4%). Median time to progression on second line chemotherapy was 9.0 (5.8-17.6) months and second line hormonal therapy +/- targeted agent was 4.0 (3.4-8.6) months (P = 0.012). Conclusions: The real-world outcomes of first-line use of CDK4/6i and AI are encouraging. PR negative tumors and dose reduction appear to be negative prognostic markers. CDK4/6i + AI as first-line treatment for HR-positive, HER2-negative MBC in Alberta is justified based on favorable PFS and early OS outcomes.

12008 Background: Many patients with metastatic cancer receive high-cost, low-value care near the end of life. We examined interventions during terminal hospitalizations for patients with metastatic cancer to identify those with high likelihood of receiving futile care. Methods: A retrospective population-based cohort analysis of encounter-level data from the National Inpatient Sample was conducted, including records from 2010-2017 for patients ages ≥18 with metastatic cancer who died during hospitalization. We fit multivariable binomial logistic regression models to examine associations between exposures, including patient demographics, and the main outcome of aggressive, low-value, and high-cost medical care (Table). Results: Out of 321,898 hospitalizations among patients with metastatic cancer, 21,335 (6.6%) were terminal. Of these, 65.9% were white, 14.1% Black, 7.5% Hispanic, 58.2% were insured by Medicare or Medicaid, and 33.2% were privately insured. Overall, 63.2% were admitted from the Emergency Department (ED), 4.6% received systemic therapy, and 19.2% received invasive ventilation. Median total charges were $43,681. Black patients and publicly insured patients had higher likelihoods of admission from the ED and receiving ventilation, as well as higher total charges; similar trends emerged among patients of Asian race and Hispanic ethnicity. Patients hospitalized at urban teaching hospitals had higher likelihoods of receiving systemic therapy, ventilation, and incurring higher total charges (Table). Conclusions: Metastatic cancer patients of racial and ethnic minority groups and those with Medicare or Medicaid were more likely to receive low-value, aggressive interventions at the end of life. Further studies are needed to determine the underlying causes of these disparities in order to implement prospective interventions and advance appropriate end-of-life care.[Table: see text]

415 Background: Metastatic urothelial carcinoma (mUC) is an aggressive disease with a median overall survival (OS) of ≈ 15 months. In the first-line setting, key prognostic factors include ECOG performance status, white blood cell count, and response to treatment per the Galsky nomogram. Bone metastases (BM) in mUC are associated with morbidity and mortality but are grouped with visceral disease; hence, their impact on prognosis is not well established. We aimed to assess the survival impact of BM in mUC patients treated with first-line platinum-based chemotherapy (PBC). Methods: A retrospective collection of patient and tumor characteristics, with clinical response to treatment (complete response [CR], partial response [PR]; stable disease [SD] or progressive disease [PD]) for patients treated at Princess Margaret Cancer Centre, Tom Baker Cancer Centre, and Cross Cancer Institute from 2005-2018 was performed. Progression-free survival (PFS) and OS were estimated using the Kaplan-Meier method. Univariate (UVA) followed by multivariate analysis (MVA) of patient variables [Cox] using PFS and OS was performed. Results: Overall 376 mUC patients were included; 222 (59%) had soft-tissue metastases (STM) only, 70 (19%) had bone-only metastases, and 84 (22%) had both STM and BM. Overall, 35% had PR or CR, 19% had SD, and 39% had PD (7%: unknown response). The median PFS and OS for the whole cohort were 5.6 months (95%CI: 4.8-6.4) and 9.7 months (95% CI: 8.8-10.8) respectively. Select UVA by metastatic site showed inferior PFS for bone-only (p=0.03) and combination STM and BM (p=0.017). Only combination STM and BM were significant on UVA for OS (p=0.002). MVA showed that bone-only metastases (p=0.03) and ECOG 3-4 (p<0.0001) were associated with worse PFS (Table). Predictors of worse OS were the combination of STM and BM (p=0.02), ECOG 3-4 (p=0.001), and WBCs ≥ULN (p=0.02), (Table). Conclusions: BM are a significant predictor of worse outcomes for mUC patients treated with first-line PBC. Consideration as a treatment stratification factor for future studies is suggested. Strategies for the treatment of mUC patients with BM (ie: bone targeted agents) in the first-line setting should be addressed in future trials. [Table: see text]
