Abstract
Venous thromboembolism (VTE) is a common occurrence in cancer and chemotherapy increases thrombosis risk. Current risk assessment models such as the Khorana score (KS) and its modifications have limitations in female cancers. We assessed the coagulation profile of a group of women cancer patients under chemotherapy using thromboelastography (TEG) to determine if this can inform VTE risk assessment. Cancer patients who planned to receive chemotherapy were recruited. Baseline demographics, cancer data, BMI, Khorana Score (KS), and VTE risk factors were recorded and patients were followed for 6 months, for any thrombotic events. A total of 36 patients aged 35-85 (18 breast, 11 endometrial, 7 ovarian cancer) were evaluated. Hypercoagulability was detected in 63% of patients post-chemo cycle 1 and 75% post-cycle 2, with a significant increase in MA (maximum amplitude) and CI (clotting index), reduction in R (reaction time), K (clot kinetics), and LY30 (lysis time after 30 min of MA). KS showed only 7% of patients were high risk, 23% were low, and 70% were intermediate risk. MA and CI significantly increased in patients with intermediate and high-risk KS when compared with the low-risk patients and MA was positively correlated with KS. Five patients developed actual VTE; 100% of the tested ones were hypercoagulable either post-cycle 1 or 2 and 80% were KS intermediate risk. TEG is a hypercoagulability marker and TEG-MA and CI can potentially assess VTE risk. Larger studies are needed to assess the utility of TEG as an adjuvant to KS to better predict VTE in specific female cancers.

Abstract
BACKGROUND Faced with expansion of molecular tumor biomarker profiling, the molecular genetics laboratory at Kingston Health Science Centre experienced significant pressures to maintain the provincially mandated 2-week turnaround time (TAT) for lung cancer (LC) patients. We used quality improvement methodology to identify opportunities for improved efficiencies and report the impact of the initiative. METHODS We set a target of reducing average TAT from accessioning to clinical molecular lab report for LC patients. Process measures included percentage of cases reaching TAT within target and number of cases. We developed a value stream map and used lean methodology to identify baseline inefficiencies. Plan-Do-Study-Act cycles were implemented to streamline, standardize, and automate laboratory workflows. Statistical process control (SPC) charts assessed for significance by special cause variation. RESULTS A total of 257 LC cases were included (39 baseline January-May 2021; 218 post-expansion of testing June 2021). The average time for baseline TAT was 12.8 days, peaking at 23.4 days after expansion of testing, and improved to 13.9 days following improvement interventions, demonstrating statistical significance by special cause variation (nonrandom variation) on SPC charts. CONCLUSIONS The implementation of standardized manual and automated laboratory processes improved timeliness of biomarker reporting despite the increasing volume of testing at our center.

Abstract
Aplastic anemia is a rare but potentially serious complication of immune checkpoint inhibitor therapy. The authors present a case of pembrolizumab-induced aplastic anemia that was refractory to steroids but had some hematologic response to modified-dosing antithymocyte globulin (ATG). This is the first reported case of hematological response to ATG for immune checkpoint inhibitor-induced aplastic anemia and the first reported case of modified ATG dosing for this indication. Cases of immune checkpoint inhibitor-induced aplastic anemia and management options are also summarized. Given the high morbidity and mortality associated with ICI-induced aplastic anemia, more data is necessary to guide evidence-based management recommendations.

Abstract
CCTG IND.236: A Phase 1b trial of combined CFI-402257 and weekly paclitaxel in patients with HER2-negative (HER2-) advanced breast cancer (aBC) Philippe L. Bedard, Mihaela Mates, John Hilton, Nathalie Levasseur, Arif Awan, Amirrtha Srikanthan, David Cescon, Karen Gelmon, Andrew Robinson, Nancy Drummond-Ivars, Irene Li, Laleh Rastgou, Jackie Edwards, Linda Hagerman, Siwei Zhang, Mark Bray, Lesley Seymour, Moira Rushton-Marovac, Pierre-Olivier Gaudreau Background: CFI-402257 is a selective oral inhibitor of TTK protein kinase, a critical regulator of the mitotic spindle assembly checkpoint overexpressed in breast cancer (BC). CFI-402257 monotherapy has anti-proliferative and cytotoxic activity and enhances antitumor activity of paclitaxel in BC xenograft models. Material and methods: Primary objectives were to establish safety and Recommended Phase 2 dose (RP2D) of CFI-402257 combined with weekly paclitaxel (Phase 1b) and Overall Response Rate (ORR) as per RECIST 1.1 (Phase 2). Patients with HER2- aBC with adequate organ function, PS 0-1, previously treated with >1 non-taxane chemotherapy, were eligible. A 3+3 design was used for Phase 1b, with dose limiting toxicities (DLTs) assessed during cycle 1 (28 days). Starting dose CFI-402257 was 84mg (DL1 = 84mg, DL2 = 112mg, DL3 = 168mg, DL4 = 210mg and DL5 = 252mg) on a 2-day on, 5-day off schedule with paclitaxel 80mg/m2 day 1, 8, 15. Safety assessments were performed weekly (CTCAE v5.0) and response every 2 cycles. A Simon 2-stage design was used for Phase 2 (stage 2 required ≥4 responses in 17 evaluable patients from stage 1). Results: 37 patients received a total of 260 cycles including all 5 dose levels. Median age was 59; 92% ER+/HER2-; 49% PS1; 22% 3 prior chemotherapy lines; 41% 4 sites of metastatic disease, and 81% had received prior CDK4/6 inhibitors. Grade 3 hematological adverse events (AEs, all dose levels) were neutropenia (70%), lymphopenia (41%) and anemia (14%). Six DLTs occurred: 5 dose-related grade 4 neutropenia and 1 febrile neutropenia. Three DLTs occurred at DL3, two at DL4, and one at DL5. Three serious AEs (two at DL3, and one at DL4) at least possibly related to treatment were seen: 2 febrile neutropenia and 1 skin infection (all grade 3). Frequent AEs (˃5%; all dose levels) considered at least possibly related to treatment were: diarrhea (38%), nausea (30%), fatigue (27%), vomiting (16%), anorexia (14%), maculo-papular rash (14%), oral mucositis (11%), alopecia (11%) and pruritus (8%). DL3 (168mg) was selected as RP2D. ORR was 3/36=8% and 1/17=5.9% in all vs Phase 2 evaluable patients, respectively. Clinical Benefit Rate (CBR; defined as complete response, partial response or stable disease ˃16 weeks in duration) was 18/33=54.6% and 10/17=58.8% in all vs Phase 2 evaluable patients, respectively. During Phase 2, the 17 evaluable patients from stage 1 did not meet pre-specified threshold for anti-tumor activity to proceed to stage 2. Conclusions: CFI-402257 and paclitaxel was well tolerated, with neutropenia as the main toxicity. DL3 (168mg) was selected as RP2D. Phase 2 ORR and CBR was 5.9% and 58.8%, respectively; during Phase 2, the 17 evaluable patients from stage 1 did not meet the pre-specified threshold for anti-tumor activity to proceed to stage 2 and the trial was closed to accrual on April 7, 2022.

Abstract
Abstract
INTRODUCTION The incidence of breast cancer is on the rise in the younger population, with 23 percent of all breast cancer diagnoses occurring in those under the age of 50. In Canada, screening mammography in women at average risk of breast cancer is recommended after the age of 50. Breast cancer in younger women is biologically more aggressive with greater rates of recurrence and metastatic disease. The sensitivity of mammograms to detect clinical breast abnormalities may be reduced due to increased breast density in this age group, leading to potential delayed diagnosis and poor outcomes. The frequency of false-negative diagnostic mammograms in young women is unknown. The purpose of this study is to describe the outcomes of diagnostic breast imaging in young women undergoing investigations for abnormal clinical breast findings and the frequency of delayed breast cancer diagnosis (more than 6 months after initial diagnostic mammography). METHODS We conducted a retrospective electronic chart review in women at average risk of breast cancer, aged between 30 and 50, who underwent diagnostic mammograms and/or breast ultrasounds (US) at our institution between 2018 to 2019 for symptomatic clinical presentations (breast pain, palpable mass, nipple discharge or breast skin changes). Patients undergoing routine screening mammograms were excluded. We collected demographics, findings of initial and follow-up breast imaging (using the Breast Imaging Reporting and Data System (BI-RADS) & breast density), and breast cancer diagnosis timelines where applicable. The primary outcome measure was the frequency of delayed breast cancer diagnosis defined as > 6 months from initial diagnostic imaging. Secondary outcomes included completion of recommended follow-up investigations and their outcomes, total number of breast cancer diagnoses and stage. The study was approved by the local research ethics board and the results were summarized using descriptive analysis. RESULTS We reviewed 400 electronic charts and identified 171 eligible patients. Mean age was 38 years; initial breast imaging included both diagnostic mammogram and US in 168 (87%), US alone in 20 (12%) and mammogram alone in 3 (2%) patients. Breast density was not routinely reported during this time frame. Ninety patients (53%) had benign findings (BIRADS 1 and 2), 41 (24%) had probable benign findings requiring short-term follow-up (BIRADS 3) while 30 (18%) patients had findings suspicious of malignancy (BIRADS 4&5) with biopsy recommended for diagnosis. In the BIRADS 3 group, 93% had recommended follow-up at a median of 7.6 months. Breast US alone was the most common subsequent investigation of which 15 % were benign lesions (BIRADS 1 & 2) and 68% remained in the BIRADS 3 category, while none were scored BIRADS 4 or 5. Among patients with BIRADS 4 & 5 scores, 83% underwent recommended biopsy at a median time of 3 weeks. Ten (6%) out of all 171 patients were diagnosed with breast cancer, all of which had BIRADS 4 or 5 on initial diagnostic imaging. Stage distribution was as follows: stage 0 - 2 patients, stage 1- 7 patients and stage 2 - 1 patients with no locally advanced or metastatic disease. The mean time from initial imaging to breast cancer diagnosis was 1.5 weeks (range 1 to 22 weeks). None of the patients had delayed breast cancer diagnosis in our cohort. CONCLUSION More than half of patients with clinical breast findings in our cohort had benign findings on diagnostic mammogram and/or US (BIRADS 1&2) with no subsequent breast diagnosis. Majority of patients requiring further investigations (BIRADS 0, 3, 4 and 5) underwent recommended follow-up (imaging or biopsy). Ultimately, a total of 10 patients were diagnosed with breast cancer at a median time of 1.5 weeks from original diagnostic imaging with no delayed breast cancer diagnosis. We, therefore, conclude that diagnostic mammograms and US are appropriate diagnostic investigations for clinical breast concerns in women between 30-50 years.

Abstract
Optimal dosing interval of bone-targeting agents (BTAs) has not been fully defined. Study of 4 vs 12-weekly BTAs in breast or prostate cancer pts with bone metastases. Study arms showed no significant differences SSE rates, time to SSEs or toxicity. There were however significant differences in cost-effectiveness results. On study SSE (12-weekly arm) associated with slight increase in subsequent SSEs.
Background We present the 2-year results of a randomised trial comparing 4- versus 12-weekly bone-targeting agents (BTAs) in patients with bone metastases from breast or castration-resistant prostate cancer (CRPC). Patients and Methods Patients with bone metastases from breast or CRPC, who were going to start or were already receiving BTAs, were randomised to 4- or 12-weekly BTA treatment for 2 years. The endpoints were: symptomatic skeletal events (SSE) rates, time to SSEs, toxicity and cost-effectiveness. Results Of 263 patients (160 breast cancer, 103 CRPC), 133 (50.6%) and 130 (49.4%) were randomised to the 4- and 12-weekly groups, respectively. BTAs included denosumab (56.3%), zoledronate (24.0%) and pamidronate (19.8%). After 2 years, the cumulative incidence rate (95% CI) of SSEs was 32.7% (24.6% to 41.1%) and 28.1% (20.3% to 36.4%) for the 4- and 12-weekly intervention groups respectively. The hazard ratio for time to first SSE was 0.96 (95% CI = 0.63 to 1.47). However, in a post hoc analysis, those patients who had an on-study SSE, there was a small non-statistical increased risk of subsequent SSEs among patients on the 12-weekly dosing arm (HR = 1.14; 95% CI – 0.90–1.44). BTA-related toxicity rates were similar between study arms. A cost-utility analysis showed that 12-weekly BTA is cost-effective from a public payer’s perspective. Conclusion These results in addition to those previously reported for de-escalating zoledronate, would support that de-escalation of commonly used BTAs is a reasonable and economically valid treatment option. While not statistically significant, the increase in subsequent SSEs in the 12-weekly arm requires further exploration.

Abstract
We report a case of dermatomyositis in a 59-year old female with advanced non-small-cell lung cancer post one cycle of first-line pembrolizumab monotherapy. Her symptoms resolved with high-dose methyl-prednisolone and subsequent prolonged oral prednisone taper over 11 weeks. She achieved durable response over 6 months without further pembrolizumab and was successfully rechallenged without recurrent high-grade immunotoxicity. To our knowledge, this is the only case of severe immune-related dermatomyositis successfully rechallenged with immunotherapy. In this case report, we highlight that dermatomyositis remains a clinical diagnosis with no reliable autoimmune antibody marker. It is a rare immune-related adverse event for which clinicians must remain highly vigilant. We also discuss the rationale and clinical factors to consider on immunotherapy rechallenge decisions.

Abstract
BACKGROUND Metformin has been associated with lower breast cancer (BC) risk and improved outcomes in observational studies. Multiple biologic mechanisms have been proposed, including a recent report of altered sex hormones. We evaluated the effect of metformin on sex hormones in MA.32, a phase III trial of nondiabetic BC subjects who were randomly assigned to metformin or placebo. METHODS We studied the subgroup of postmenopausal hormone receptor-negative BC subjects not receiving endocrine treatment who provided fasting blood at baseline and at 6 months after being randomly assigned. Sex hormone-binding globulin, bioavailable testosterone, and estradiol levels were assayed using electrochemiluminescence immunoassay. Change from baseline to 6 months between study arms was compared using Wilcoxon sum rank tests and regression models. RESULTS 312 women were eligible (141 metformin vs 171 placebo); the majority of subjects in each arm had T1/2, N0, HER2-negative BC and had received (neo)adjuvant chemotherapy. Mean age was 58.1 (SD=6.9) vs 57.5 (SD=7.9) years, mean body mass index (BMI) was 27.3 (SD=5.5) vs 28.9 (SD=6.4) kg/m2 for metformin vs placebo, respectively. Median estradiol decreased between baseline and 6 months on metformin vs placebo (-5.7 vs 0 pmol/L; P < .001) in univariable analysis and after controlling for baseline BMI and BMI change (P < .001). There was no change in sex hormone-binding globulin or bioavailable testosterone. CONCLUSION Metformin lowered estradiol levels, independent of BMI. This observation suggests a new metformin effect that has potential relevance to estrogen sensitive cancers.

Abstract
BACKGROUND Optimal dosing of bone-targeted agents (BTAs), in patients with bone metastases remains an important clinical question. This trial compared 4-weekly versus 12-weekly therapy. PATIENTS AND METHODS Patients with bone metastases from breast or castration-resistant prostate cancer (CRPC), who were going to start or already on BTAs, were randomised 1:1 to 4-weekly or 12-weekly BTA treatment for one year. Primary end point was change in health-related quality of life (HRQoL)-physical function European Organisation for Research and Treatment of Cancer (EORTC)-QLQ-C30). Secondary end points included pain (EORTC-QLQ-BM22), global health status (EORTC-QLQ-C30), symptomatic skeletal events (SSEs) rates and time to SSEs. Primary analysis was per protocol and a non-inferiority margin of 5 points was used. RESULTS Of 263 patients (160 breast cancer, 103 CRPC), 133 (50.6%) and 130 (49.4%) were randomised to the 4- and 12-weekly groups, respectively. BTAs included denosumab (56.3%), zoledronate (24.0%) and pamidronate (19.8%). Using repeated-measures analysis, across all time points, patients in the 4-weekly arm had a mean HRQL-physical subdomain score which was 1.2 (95% confidence interval: -1.6 to 4.0) higher than the 12-weekly arm. The study met the definition of non-inferiority for our primary outcome. Secondary outcomes showed no significant difference in scores for pain, global health status, SSE rates and SSE-free survival between arms. Subgroup analyses for cancer type, prior BTA use or BTA type showed no significant difference between arms. CONCLUSION These results in addition to those previously reported for de-escalating zoledronate and systematic reviews in both breast and prostate cancers, would support that de-escalation of commonly used BTAs is a reasonable treatment option.

Abstract
Adjuvant bisphosphonates are an established standard in postmenopausal breast cancer. Guidelines note the need to explore different agents, doses, and intervals of bisphosphonates. Feasibility of randomizing to 6-monthly vs one dose of IV zoledronate was demonstrated.
Background Adjuvant zoledronate is widely used in patients with early stage breast cancer (EBC), but its optimal duration and dosing interval is still unknown. While a single-dose of zoledronate can improve bone density for many years, a proper evaluation of its effects on breast cancer-related outcomes would require a large trial. In this pilot study we evaluated the feasibility of performing such a trial. Methods Eligible patients with EBC were randomised to receive either one dose of zoledronate or 7 doses (6-monthly dosing for 3 years). Feasibility was assessed by a combination of primary outcomes including: activation of at least 6 Ontario sites within a year, active participation (i.e. approaching eligible patients for study participation) of at least half of the medical oncologists, and enrolment of at least 100 patients across all sites within 9 months of the sixth site being activated. Results All 6 sites were activated within 1 year and of 47 medical oncologists, 27 (57%) approached patients. Between November 2018 and April 2020, 211 eligible patients were randomised, 106 (50.2%) to a single dose of zoledronate and 105 (49.8%) to 6-monthly dosing. Baseline characteristics of randomised patients included; median age 59 (range 36–88), ER and/or PR positive (85%), Her2 positive (23%), menopausal status (premenopausal [19%], perimenopausal [6.7%] and postmenopausal [74%]) and 74% received neo/adjuvant chemotherapy. Conclusions All study feasibility endpoints were met in this trial comparing alternative schedules for adjuvant zoledronate. We will now seek funding for performing a larger efficacy trial. Trial registration: NCT03664687.

Abstract
Purpose Despite triple antiemetic therapy use for breast cancer patients receiving emetogenic chemotherapy, nausea remains a clinical challenge. We evaluated adding olanzapine (5 mg) to triple therapy on nausea control in patients at high personal risk of chemotherapy-induced nausea and vomiting (CINV). Methods This multi-centre, placebo-controlled, double-blind trial randomized breast cancer patients scheduled to receive neo/adjuvant chemotherapy with anthracycline-cyclophosphamide or platinum-based chemotherapy to olanzapine (5 mg, days 1–4) or placebo. Primary endpoint was frequency of self-reported significant nausea, repeated for all cycles of chemotherapy. Secondary endpoints included: duration of nausea, overall total control of CINV, Health Related Quality of Life (HRQoL) using FLIE questionnaire, use of rescue mediation and treatment-related adverse events. Results 218 eligible patients were randomised to placebo (105) or olanzapine (113). From days 0–5 following each cycle of chemotherapy, 41.3% (95%CI: 36.1–46.7%) of patients in the placebo group reported significant nausea compared to 27.7% (95%CI: 23.2–32.4%) in the olanzapine group (p = 0.001). Across all cycles of chemotherapy, patients receiving olanzapine experienced a statistically significant improvement in HRQoL (p < 0.001). Grade 1/2 sedation was the most commonly side effect reported at 40.8% in the placebo group vs. 54.1% with olanzapine (p < 0.001). Conclusion In patients at high personal risk of CINV, the addition of olanzapine 5 mg daily to standard antiemetic therapy significantly improves the control of nausea, HRQoL, with no unexpected toxicities. Double-blind trial evaluated the addition of olanzapine to triple therapy in patients at high personal risk of CINV. Adding 5 mg olanzapine was associated with significantly improved nausea control with no unexpected toxicities. Olanzapine plus triple therapy should be considered standard of care for breast cancer patients at high risk of CINV.

Abstract
Abstract
Background
The trial collected prospective data from physiology measurements of borderline lesions in five Czech, one Japan and one Argentinian cathlabs. The main purposes were to analyze diagnostic agreement between FFR (fractional flow reserve) and iFR (instantaneous wave free ratio) examinations and to find possible explanations for discrepant results.
Methods
FFR and iFR examinations were analyzed using Philips-Volcano console and coronary flow reserve (CFR) was analyzed by using Combomap machine Philips-Volcano. Hyperemia for FFR and CFR measurements was induced by intracoronary administration of adenosine. We used CFR as a truth for comparison between FFR and iFR, because CFR has higher impact on patients prognosis than pressures indices.
Results
Data were collected from February 2016 to June 2019 and the database includes 1.789 examinations from 1.492 patients (282 of them, 15.8%, with ACS). CFR were measured in 343 lesions in 293 patients. (ACS 31.2%). Overall correlation between FFR and iFR is high (R=0.86 p<0.0001). The FFR/iFR discrepancy occurred in 84 measurements (24.5%), more frequently it was FFRp (positive) / iFRn (negative) type of discrepancy (65, 18.9%) compare to FFRn/iFRp (19, 5.5%) one. There was no difference in occurrence of FFR/iFR discrepancy in stable patients and ACS ones (25.1%vs. 22.4%, p=0.59). The CFR correlated better with iFR than with FFR (R=0.56, p<0.0001 vs. R= 0.36, p<0.0001) (see table). In lesions with FFRp/iFRn type of discrepancy we found substantially higher CFR value compared to FFR/iFR agreement group (2.4±0.7 vs. 1.5±0.5, p<0.0001). Unlike to FFRn/iFRp discrepancy, where CFR value was similar with agreement group (1.4±0.1 vs. 1.5±0.1, p=0.25)
Conclusion
The FFR/iFR discrepancy occurred in almost one quarter of examinations. Correlation between CFR and iFR is better than between CFR and FFR. High flow is probably one of the main reason for FFRp/iFRn type of discrepancy.

Abstract
9502 Background: First-line therapy for advanced NSCLC includes PD-1 checkpoint inhibitor (ICI) monotherapy, and in combination with chemotherapy. Combination ICI have also demonstrated better survival compared to chemotherapy (CM-227). In CCTG BR.34, we compared overall survival (OS) in patients with advanced NSCLC receiving first-line durvalumab plus tremelimumab (DT) with or without platinum doublet chemotherapy (CT). Methods: This international, open-label, randomized trial accrued 301 participants from Canada and Australia, with stage IV NSCLC, EGFR/ALK wildtype, ECOG PS 0/1. Patients were randomized to DT for 4 cycles or DT+CT (pemetrexed- or gemcitabine-platinum), with ongoing D or D + pemetrexed (non-squamous) maintenance until disease progression. Stratification factors included histology, stage IVA v. IVB and smoking status. The primary endpoint was OS; secondary endpoints included progression-free survival (PFS), objective response rate (ORR = CR + PR) and adverse events (AEs). Results: At a median follow up of 16.6 months, no significant difference in OS was seen between the two treatment arms, with a median OS of 16.6 months with DT+CT v. 14.1 months with DT, (estimated HR 0.88, 90% CI 0.67-1.16). PFS was significantly improved in the DT+CT arm (stratified HR 0.67, 95% CI 0.52-0.88; medians 7.7 v. 3.2 months). ORR was higher in the DT+CT arm, 28% v. 14%, (odds ratio 2.1, p=0.001). Preplanned subgroup analysis demonstrated no significant differences in treatment outcomes by plasma TMB (<20 v. ≥20 mut/Mb, Guardant OMNI), age, sex, or smoking status. There was a trend to improved OS with DT+CT in the subgroup with PD-L1 TPS≥50%, (HR 0.64, 95% CI 0.40-1.04, p=0.07). Plasma TMB<20 mut/Mb was associated with shorter survival in both treatment groups (HR 1.99, 95% 1.3-3.1). Toxicity was greater in the DT+CT arm, with grade≥3 adverse events in 82% v. 70%, (p=0.02), most commonly dyspnea, nausea and cough. The incidence of immune-related adverse events was similar between arms (colitis 11%, pneumonitis 6%, endocrinopathy 21%). Grade 5 events occurred in 2.7%, (5 with DT+CT, 3 with DT). Conclusions: The addition of CT to first-line DT did not improve OS in advanced NSCLC. CT+DT improved ORR and PFS, and was associated with greater toxicity. No differential effects were seen by PD-L1 TPS nor bTMB. These data suggest that adding chemotherapy to ICI may be beneficial in those with PD-L1 TPS >=50%, and warrant further analysis in independent datasets. Clinical trial information: NCT03057106 .

Abstract
BACKGROUND The optimal duration of filgrastim as primary febrile neutropenia (FN) prophylaxis in early breast cancer patients is unknown, with 5, 7 or 10 days being commonly prescribed. This trial evaluates whether 5 days of filgrastim was non-inferior to 7/10 days. PATIENTS AND METHODS In this randomised, open-label trial, early breast cancer patients who were to receive filgrastim as primary FN prophylaxis were randomly allocated to 5 versus 7 versus 10 days of filgrastim for all chemotherapy cycles. A protocol amendment in November 2017 allowed subsequent patients (N = 324) to be randomised to either 5 or 7/10 days. The primary outcome was a composite of either FN or treatment-related hospitalisations. Secondary outcomes included chemotherapy dose reductions, delays and discontinuations. Analyses were carried out by per protocol (primary) and intention-to-treat, and the non-inferiority margin was set at 3% for the risk of having FN and/or hospitalisation per cycle of chemotherapy. RESULTS Patients (N = 466) were randomised to receive 5 (184, 39.5%), or 7/10 (282, 60.5%) days of filgrastim. In our primary analysis, the difference in risk of either FN or treatment-related hospitalisation per cycle was -1.52% [95% confidence interval (CI): -3.22% to 0.19%] suggesting non-inferiority of a 5-day filgrastim schedule compared with 7/10-days. The difference in events per cycle for FN was 0.11% (95% CI: -1.05 to 1.27) while for treatment-related hospitalisations it was -1.68% (95% CI: -2.73% to -0.63%). The overall proportions of patients having at least one occurrence of either FN or treatment-related hospitalisation were 11.8% and 14.96% for the 5- and 7/10-day groups, respectively (risk difference: -3.17%, 95% CI: -9.51% to 3.18%). CONCLUSION Five days of filgrastim was non-inferior to 7/10 days. Given the cost and toxicity of this agent, 5 days should be considered standard of care. CLINICALTRIALS.

Abstract
This multicenter phase Ib study aimed to establish a recommended phase II dose for durvalumab (Du) ± tremelimumab (Tr) in combination with standard platinum-doublet chemotherapy. Eligible patients were enrolled into one of six dose levels (DL) of Du ± Tr which included concomitant treatment with standard platinum-doublet regimens; (pemetrexed, gemcitabine, etoposide, (each with cisplatin or carboplatin) or nab-paclitaxel (with carboplatin)). Dose escalation was according to a Rolling Six type design. Both weight-based and fixed dosing of Du and Tr were explored. Du was continued until progression. Tr dosing was finite (up to 6 doses) with increasing dose and/or frequency by DL. 136 patients were enrolled. The majority of drug-related adverse events (AEs) were ≤ grade 2 and attributable to chemotherapy. AEs considered related to immunotherapy were mainly ≤ grade 2; the most frequent (occurring ≥10 %) were colitis/diarrhea, skin, and thyroid dysfunction. Seven patients had DLTs including pneumonitis, myocarditis, diarrhea, encephalitis, motor neuropathy, and enterocolitis. There were 2 treatment-related deaths. Tr and Du exposures did not appear affected by chemotherapy. Among the 73 non-small cell lung cancer (NSCLC) patients treated, the objective response rate was 51 % (95 %CI = 38.7-62.6 %) with a median progression-free and overall survival of 6.5 months (95 % CI = 5.5-9.4 months) and 19.8 months (95 % CI = 14.8 months - not yet reached) respectively. Anti-tumour activity was observed across PD-L1 subtypes. Du 1500 mg q3w and Tr 75 mg q3wx5 can be safely combined with platinum-doublet chemotherapy. Efficacy among NSCLC patients appears comparable to results from other immunotherapy and chemotherapy combination trials. NCT02537418.

Abstract
Abstract
Background: TreatER+ight is the 1st prospective observational study in Canadian HR+ HER2- advanced breast cancer patients currently receiving endocrine therapy (ET) alone or in combination with targeted therapy (TT) (NCT02753686).
Methods: This exploratory analysis displays real-world evidence on baseline demographics, treatment patterns, sequencing, and method of access to therapy. More specifically this abstract focuses on treatment decisions around CDK4/6-based therapy at various lines of treatment. At data cut-off of April 1st 2019, 305 patients were enrolled from 24 sites since Mar'16 with 113 patients receiving CDK4/6is at baseline. 300 patients were evaluable for treatment analysis.
Results:

Conclusions: The majority of patients enrolled (66.6%) are receiving combination therapy with the most common treatment being a CDK4/6-based therapy (56.5%). Of the patients receiving CDK4/6 at baseline a majority are receiving this therapy in the 1L (53.1%) and 2L (33.6%), with the median duration on therapy of respectively 8.87 and 8.77 months. For patients receiving CDK4/6 therapy in 1L, the most common 2L treatment is either endocrine therapy single agent and in certain parts of the country everolimus + exemestane. Further sequencing information will be analyzed and shared for this abstract.

Abstract
11501 Background: Defining the optimal dosing interval of commonly used bone-targeted agents (BTAs), such as denosumab and bisphosphonates, for patients with bone metastases remains an important clinical question. We performed a pragmatic randomised trial comparing the non-inferiority of 12- versus 4-weekly BTAs in patients with bone metastases from breast and prostate cancer. Methods: Patients with bone metastases, who were either BTA-naïve, or already receiving, denosumab, pamidronate or zoledronate were eligible. They were randomised to receive their chosen BTA every 12- or 4-weeks for one year. The primary endpoint was Health related quality of life (HRQL) (EORTC-QLQ-C30 Functional Domain - Physical Subdomain). Secondary endpoints included: pain (EORTC-QLQ-BM22 - pain domain), Global Health Status (EORTC-QLQ-C30), symptomatic skeletal events (SSE) rates and time to SSEs. Adverse events and toxicity profiles were also compared. Results: Of 263 patients (60.8% breast and 39.2% prostate), 130 (49.4%) were randomised to 12-weekly and 133 (50.6%) to 4-weekly therapy. 138 (52.5%) were bone-agent naïve. The BTAs included; denosumab (n=148, 56.3%), zoledronate (n=63, 24.0%) and pamidronate (n=52, 19.8%). Study-reported outcomes showed no significant difference in; HRQL-physical domain (median [range]: 0 [-86, 40] vs. 0 [-66, 53.3]), pain (median [range]: 0 [-66, 72] vs. 0 [-100, 88]), Global Health Status (median [range]: 0 [-100, 66.7] vs. 0 [-83, 33.3]), SSE rates (N [%]: 24 [18.5%] vs. 22 [16.5%]), 1-year SSE-free rate (median, range; 73.2% [63.6, 80.7] vs. 77.9% [69.1, 84.4]) between the 12- and 4-weekly arms, respectively. Subgroup analyses for BTA naïve and pre-treated patients, and for patients receiving denosumab, zoledronate and pamidronate, showed no significant difference between the 12- and 4-weekly arms. There was no significant difference in reported rates of renal impairment (2.3% vs. 3.0%), symptomatic hypocalcaemia (1.5% vs. 1.5%) or osteonecrosis of the jaw (0.8% vs. 0.8%). Conclusion: The findings of this trial are consistent with those previously reported for de-escalating zoledronate. This trial also included patients receiving de-escalated denosumab and pamidronate. While the results of the Swiss REDUSE trial are awaited, the data presented would suggest that de-escalation of all commonly used BTAs is a reasonable treatment option. Clinical trial information: NCT02721433.

Abstract
PURPOSE CheckMate 568 is an open-label phase II trial that evaluated the efficacy and safety of nivolumab plus low-dose ipilimumab as first-line treatment of advanced/metastatic non–small-cell lung cancer (NSCLC). We assessed the association of efficacy with programmed death ligand 1 (PD-L1) expression and tumor mutational burden (TMB). PATIENTS AND METHODS Two hundred eighty-eight patients with previously untreated, recurrent stage IIIB/IV NSCLC received nivolumab 3 mg/kg every 2 weeks plus ipilimumab 1 mg/kg every 6 weeks. The primary end point was objective response rate (ORR) in patients with 1% or more and less than 1% tumor PD-L1 expression. Efficacy on the basis of TMB (FoundationOne CDx assay) was a secondary end point. RESULTS Of treated patients with tumor available for testing, 252 patients (88%) of 288 were evaluable for PD-L1 expression and 98 patients (82%) of 120 for TMB. ORR was 30% overall and 41% and 15% in patients with 1% or greater and less than 1% tumor PD-L1 expression, respectively. ORR increased with higher TMB, plateauing at 10 or more mutations/megabase (mut/Mb). Regardless of PD-L1 expression, ORRs were higher in patients with TMB of 10 or more mut/Mb (n = 48: PD-L1, ≥ 1%, 48%; PD-L1, < 1%, 47%) versus TMB of fewer than 10 mut/Mb (n = 50: PD-L1, ≥ 1%, 18%; PD-L1, < 1%, 5%), and progression-free survival was longer in patients with TMB of 10 or more mut/Mb versus TMB of fewer than 10 mut/Mb (median, 7.1 v 2.6 months). Grade 3 to 4 treatment-related adverse events occurred in 29% of patients. CONCLUSION Nivolumab plus low-dose ipilimumab was effective and tolerable as a first-line treatment of advanced/metastatic NSCLC. TMB of 10 or more mut/Mb was associated with improved response and prolonged progression-free survival in both tumor PD-L1 expression 1% or greater and less than 1% subgroups and was thus identified as a potentially relevant cutoff in the assessment of TMB as a biomarker for first-line nivolumab plus ipilimumab.

Abstract
PURPOSE Timely lung cancer care has been associated with improved clinical outcomes and patient satisfaction. We identified improvement opportunities in lung cancer management pathways at Kingston Health Sciences Centre. Quality improvement strategies led to the implementation of a multidisciplinary lung cancer clinic (MDC). METHODS We set an outcome measure of decreasing the time from diagnosis to first cancer treatment by 10 days within 6 months of clinic implementation. We implemented a weekly MDC that involved respirologists, medical oncologists, and radiation oncologists at which patients with new lung cancer diagnoses were offered concurrent oncology consultation. We used Plan-Do-Study-Act cycles to guide our improvement initiatives. A total of five Plan-Do-Study-Act cycles spanned 14 months and consisted of an MDC pilot clinic, large-scale MDC launching, debriefing meetings, and clinic expansion. Pre-MDC data were analyzed retrospectively to establish baseline and prospectively for improvement. Statistical Process Control XmR(i) charts were used to report data. RESULTS Since MDC initiation, 128 patients have been seen in 34 MDC clinics (3.8 patients per clinic). Mean days from diagnosis to first oncology assessment decreased from 12.4 days to 3.9 days, and mean days from diagnosis to first cancer treatment decreased from 39.5 to 15.0 days, both of which demonstrated special cause variation. Time to assessment and treatment improved for patients with every stage of lung cancer and for both small-cell and non-small-cell subtypes. CONCLUSION MDC shortens the time from lung cancer diagnosis to oncology assessment and treatment. Time to treatment improved more than time to oncology assessment, which suggests the improvement is related to benefits beyond faster oncology assessment.

Abstract
Background Advanced breast cancer (abc) represents a substantial burden for patients and caregivers. In the present study, we aimed to estimate quality of life (qol), utility, productivity loss, pain, health care resource utilization, and costs for patients with abc, and qol, utility, and productivity loss for their caregivers. Methods This multicentre prospective non-interventional study was conducted in Canada. Eligible participants were postmenopausal women with estrogen receptor-positive, her2-negative unresectable abc and their caregivers. Validated questionnaires were used to measure qol, utility, productivity loss, and pain. Patients and caregivers were classified into 4 health states typically used in oncology economic modelling: first-line progression-free (1l-pf), first-line progressive disease (1l-pd), second- or subsequent-line progression-free (≥2l-pf), and second- or subsequent-line progressive disease (≥2l-pd). Results Most patients and caregivers accepted to participate, with total recruitment of 202 patients and 78 caregivers. Compared with patients in pf, patients in pd had lower mean qol scores (52.9 ± 29.9 for 1l-pd vs. 68.2 ± 23.2 for 1l-pf, and 54.0 ± 23.6 for ≥2l-pd vs. 66.0 ± 22.1 for ≥2l-pf), lower mean utility values (0.64 ± 0.22 for 1l-pd vs. 0.73 ± 0.20 for 1l-pf, and 0.65 ± 0.25 for ≥2l-pd vs. 0.74 ± 0.18 for ≥2l-pf), and greater productivity loss (39.4 ± 27.7 for 1l-pd vs. 27.5 ± 30.1 for 1l-pf, and 37.6 ± 29.2 for ≥2l-pd vs. 32.0 ± 29.0 for ≥2l-pf). Compared with caregivers of patients in pf, caregivers of patients in pd had lower qol scores and utility values, and greater productivity loss. Conclusions Study results indicate that, for patients and caregivers, pd health states are associated with a deterioration of qol and utility and a decrease in productivity in both 1l and ≥2l.

Abstract
BACKGROUND Pelareorep, a serotype 3 reovirus, has demonstrated preclinical and early clinical activity in breast cancer and synergistic cytotoxic activity with microtubule targeting agents. This multicentre, randomized, phase II trial was undertaken to evaluate the efficacy and safety of adding pelareorep to paclitaxel for patients with metastatic breast cancer (mBC). METHODS Following a safety run-in of 7 patients, 74 women with previously treated mBC were randomized either to paclitaxel 80 mg/m2 intravenously on days 1, 8, and 15 every 4 weeks plus pelareorep 3 × 1010 TCID50 intravenously on days 1, 2, 8, 9, 15, and 16 every 4 weeks (Arm A) or to paclitaxel alone (Arm B). Primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate, overall survival (OS), circulating tumour cell counts, safety, and exploratory correlative analyses. All comparisons used a two-sided test at an alpha level of 20%. Survival analyses were adjusted for prior paclitaxel. RESULTS Final analysis was performed after a median follow-up of 29.5 months. Pelareorep was well tolerated. Patients in Arm A had more favourable baseline prognostic variables. Median adjusted PFS (Arm A vs B) was 3.78 mo vs 3.38 mo (HR 1.04, 80% CI 0.76-1.43, P = 0.87). There was no difference in response rate between arms (P = 0.87). Median OS (Arm A vs B) was 17.4 mo vs 10.4 mo (HR 0.65, 80% CI 0.46-0.91, P = 0.1). CONCLUSIONS This first, phase II, randomized study of pelareorep and paclitaxel in previously treated mBC did not show a difference in PFS (the primary endpoint) or RR. However, there was a significantly longer OS for the combination. Further exploration of this regimen in mBC may be of interest.

Abstract
Abstract
Background: Pelareorep is a Dearing strain of reovirus serotype 3, with demonstrated in vitro and in vivo activity in many cancers and synergistic cytotoxic activity with microtubule targeting agents, including taxanes. This study was designed to determine the efficacy and safety of pelareorep + P compared to P alone in mBC. Materials and Methods: This randomized, open-label, phase II study enrolled subjects who had mBC previously exposed to chemotherapy (CT). Subjects were randomized 1:1 between Arm A (P 80 mg/m2 day 1, 8 and 15 q 28 days plus pelareorep 3 x 1010 TCID50 day 1,2,8,9,15,16 q 28 days) and Arm B (P 80 mg/m2 day 1, 8 and 15 q 28 days). Treatment was continued until disease progression (PD) or unacceptable toxicity. Objective response was assessed every 8 weeks. Primary endpoint was progression free survival (PFS). The study had 90% power to detect an improvement of PFS from 4 to 7.5 months (HR 0.5, two-sided α=0.2). All p-values are two-sided. Results: Between July 2012 and April 2016, 81 subjects were accrued: 7 to the safety run-in for arm A, 36 to Arm A and 38 to Arm B. All had received prior CT, 59 as adjuvant treatment and 48 for mBC. Patients in Arm A had more favorable prognostic features, including lower LDH and less prior therapy. The median cumulative dose of P was 960 mg/m2 for arm A vs. 828 mg/m2 for arm B. Similar numbers of subjects in both arms required dose reductions, predominantly for myelosuppression. The median duration of treatment was 16.1 weeks for pelareorep and P in arm A and 14.1 weeks for P in arm B. With a median follow-up of 29.5 months, the median PFS was 3.78 mo for arm A and 3.38 mo for arm B (HR 1.04, 80% CI 0.76-1.43, p=0.87). Median OS was 17.4 mo for arm A and 10.4 mo for arm B (HR 0.65, 80% CI 0.46-0.91, p=0.1). Response rates (RR) were 25% for arm A and 23.7% for arm B (p=0.87). Pre-specified subset analysis found statistically significant differences in OS in patients with ECOG 1 or 2, aged < 65 yr, and no prior P treatment. Exploratory analysis of biomarkers found significant differences in OS in patients with wild type PIK3CA, KIT, APC, PTEN, ATM, AKT1, mutated TP53, and both wild type and mutated MET, although the number of pts was small. When grade 3 or higher adverse events (AE) were considered, only the incidence of fatigue was found in ≥10% (16% on Arm A vs 13%, arm B, p=0.76). Hematologic grade 3 or higher effects observed in ≥10% patients included lymphopenia (5% arm A vs 18% arm B, p=0.08), and neutropenia (23% arm A vs 26% arm B; p=0.8). There was a statistically significant difference in grade 3 or higher LDH (0% arm A vs 13% arm B, p=0.03). There were no treatment related deaths. Conclusions: This first, phase II, randomized study of pelareorep + P vs P in mBC previously exposed to CT, did not meet its primary endpoint of PFS. Despite similar PFS and RR there was a statistically significant improvement in OS for pelareorep + P pts. Given these data, further exploration of the role of pelareorep + P in mBC may be of interest.

Abstract
3058 Background: CT is immunomodulatory and requires corticosteroids (CS) premedication. We hypothesized that the incidence of irAE may be lower when D ± T is given with CT or CS. Methods: Patients (pts) receive CT (pemetrexed, nabpaclitaxel, etoposide or gemcitabine + cisplatin or carboplatin; usual 4-6 cycles) with D ± T, followed by D ± T alone (1 year total); pts with ≥ g2 (selected) or ≥ g3 irAE discontinued D ± T. Cycles were coded as CT + D ± T or D ± T; pts could contribute to both. CS: high (dexamethasone > 10mg/day for 5 days) or low CS. irAE were D ± T related gastrointestinal (GI), skin, endocrine, neurologic, hypersensitivity, pneumonitis (PN) or other immune (nephritis (GN), pancreatitis, hepatitis). Biochemistry (BIO; all causality): creatinine, transaminases/bilirubin (LFTS) and amylase/lipase was summarised. Results: In this ongoing study, 118 pts received 723 cycles. Pts had good performance status (PS 0-1), 78 had thoracic malignancies and 84 no prior CT. 44 pts continue on D ± T alone; 32 pts continue on CT + D ± T while 76 pts discontinued D ± T primarily due to disease progression; 15 discontinued for ≥ g2 irAE [PN (3), hepatitis (1), GN (2), adrenal (1), myocarditis (1), GI (3), thrombocytopenia (1), hyperthyroidism (1), encephalitis (1), pt decision (1)]. 67 pts had high CS cycles while 78 pts had low. 50% pts had irAE and 10% had ≥ g3 irAE, most commonly skin and GI. GI (15 vs 11%), skin (26 vs 20%) and PN (3 vs 0%) were reported in more pts during CT + D ± T cycles (non significant (NS)) ; hypothyroidism was more common with D ± T alone (18 vs 10%; p = NS). IrAE rates and severity were similar between high (67 pts) or low CS (78 pts) except for GI (19 vs 10%; p = NS). BIO were more common during CT + D ± T (74% of pts vs 48% p = 0.003); rates in high CS were similar to low CS. LFTs (ALT/AST - 41% vs 16%; 38% vs 9%; p = 0.005) and amylase/lipase (18 vs 9%; 19 vs 14%; p = NS) were more common in pts with CT + D ± T cycles vs pts with D ± T alone cycles. Conclusions: There is no evidence that CT or CS abrogates irAE in this exploratory analysis. GI, skin, pneumonitis, LFTS and amylase/lipase were more common during CT + D ± T suggesting additive/multifactorial causes; hypothyroidism is more common in D ± T cycles, which may reflect time on treatment.

Abstract
Purpose To make recommendations regarding the use of bisphosphonates and other bone-modifying agents as adjuvant therapy for patients with breast cancer. Methods Cancer Care Ontario and ASCO convened a Working Group and Expert Panel to develop evidence-based recommendations informed by a systematic review of the literature. Results Adjuvant bisphosphonates were found to reduce bone recurrence and improve survival in postmenopausal patients with nonmetastatic breast cancer. In this guideline, postmenopausal includes patients with natural menopause or that induced by ovarian suppression or ablation. Absolute benefit is greater in patients who are at higher risk of recurrence, and almost all trials were conducted in patients who also received systemic therapy. Most studies evaluated zoledronic acid or clodronate, and data are extremely limited for other bisphosphonates. While denosumab was found to reduce fractures, long-term survival data are still required. Recommendations It is recommended that, if available, zoledronic acid (4 mg intravenously every 6 months) or clodronate (1,600 mg/d orally) be considered as adjuvant therapy for postmenopausal patients with breast cancer who are deemed candidates for adjuvant systemic therapy. Further research comparing different bone-modifying agents, doses, dosing intervals, and durations is required. Risk factors for osteonecrosis of the jaw and renal impairment should be assessed, and any pending dental or oral health problems should be dealt with prior to starting treatment. Data for adjuvant denosumab look promising but are currently insufficient to make any recommendation. Use of these agents to reduce fragility fractures in patients with low bone mineral density is beyond the scope of the guideline. Recommendations are not meant to restrict such use of bone-modifying agents in these situations.

Abstract
BACKGROUND The mechanisms of resistance to anti-human epidermal growth factor receptor 2 (HER 2) therapies are unclear but may include the tyrosine-protein kinase Met (c-Met), vascular endothelial growth factor (VEGF) and AXL pathways. Foretinib is an inhibitor of c-Met, VEGF receptor 2 (VEGFR-2), platelet-derived growth factor receptor beta (PDGFRB), AXL, Fms-like tyrosine kinase 3 (FLT3), angiopoiten receptor (TIE-2), RET and RON kinases. This phase Ib study sought to establish the associated toxicities, pharmacokinetics (PK) and recommended phase II doses (RP2D) of foretinib and lapatinib in a cohort of HER-2-positive patients with metastatic breast cancer (MBC). METHODS Women with HER-2 positive MBC, Performance status (PS 0-2), and no limit on number of prior chemotherapies or lines of anti-HER-2 therapies were enrolled. A 3 + 3 dose escalation design was utilized. Four dose levels were intended with starting doses of foretinib 30 mg and lapatinib 750 mg orally once a day (OD) on a 4-weekly cycle. Assessment of c-MET status from the primary archival tissue was performed. RESULTS We enrolled 19 patients, all evaluable for toxicity assessment and for response evaluation. Median age was 60 years (34-86 years), 95% were PS 0-1, 53% were estrogen receptor-positive and 95% had at least one prior anti-HER-2-based regimen. The fourth dose level was reached (foretinib 45 mg/lapatinib 1250 mg) with dose-limiting toxicities of grade-3 diarrhea and fatigue. There was only one grade-4 non-hematological toxicity across all dose levels. There were no PK interactions between the agents. A median of two cycles was delivered across the dose levels (range 1-20) with associated progression-free survival of 3.2 months (95% CI 1.61-4.34 months). By immunohistochemical assessment with a specified cutoff, none of the 17 samples tested were classified as positive for c-Met. CONCLUSIONS The RP2D of the combined foretinib and lapatinib is 45 mg and 1000 mg PO OD, respectively. Limited activity was seen with this combination in a predominantly unselected cohort of HER-2-positive patients with MBC.

Abstract
INTRODUCTION Randomized controlled trials (rcts) are the "gold standard" for establishing treatment efficacy; however, efficacy does not automatically translate to a comparable level of effectiveness in routine practice. Our objectives were to □ describe outcomes of palliative platinum-doublet chemotherapy (ppdc) in non-small-cell lung cancer (nsclc) in routine practice, in terms of survival and well-being; and□ compare the effectiveness of ppdc in routine practice with its efficacy in rcts. METHODS Electronic treatment records were linked to the Ontario Cancer Registry to identify patients who underwent ppdc for nsclc at Ontario's regional cancer centres between April 2008 and December 2011. At each visit to the cancer centre, a patient's symptoms are recorded using the Edmonton Symptom Assessment System (esas). Score on the esas "well-being" item was used here as a proxy for quality of life (qol). Survival in the cohort was compared with survival in rcts, adjusting for differences in case mix. Changes in the esas score were measured 2 months after treatment start. The proportion of patients having improved or stable well-being was compared with the proportion having improved or stable qol in relevant rcts. RESULTS We identified 906 patients with pre-ppdcesas records. Median survival was 31 weeks compared with 28-48 weeks in rcts. After accounting for deaths and cases lost to follow-up, we estimated that, at 2 months, 62% of the cohort had improved or stable well-being compared with 55%-63% who had improved or stable qol in rcts. CONCLUSIONS The effectiveness of ppdc for nsclc in routine practice in Ontario is consistent with its efficacy in rcts, both in terms of survival and improvement in well-being.

Abstract
Abstract
Introduction:
The Oncotype DX Recurrence Score (RS) is a 21-gene signature, retrospectively validated prognostic marker and predictor of response to adjuvant chemotherapy (ACT) in estrogen receptor (ER) positive breast cancer (BC). In 2010 RS became publicly funded in Ontario for patients with estrogen-positive, HER2 negative and node negative breast cancer. The aim of our study was to explore the pattern of RS testing and use of adjuvant chemotherapy at the Cancer Centre of Southeastern Ontario (CCSEO) since the introduction of RS testing. Additionally we compared the RS tested patients with a matched cohort treated for early BC prior to 2010.
Methods:
A retrospective paper and electronic chart review was undertaken of patients with early BC (stage 1 and 2) with the following pathologic features: T1-T2, N0/N1mic, ER positive and Her-2neu negative. We collected patient demographics, co-morbidities, surgical data, tumour characteristics, ACT use, Adjuvant! mortality estimates and breast cancer outcomes. Cohort A included patients who underwent RS testing (2010 – 2013) and cohort B patients treated prior to 2010. The two cohorts were compared using chi-square tests for categorical data, and independent samples t-tests and the Mann-Whitney U for continuous data.
Results:
160 patients were included in our analysis of which 83 underwent RS testing. Compared to cohort B, cohort A was older (median age 60 versus (vs) 48, p<0.001); had higher postmenopausal status (77 vs 34%, p<0.001); higher rates of breast conserving surgery (88 vs 74%, p=0.024) and sentinel node biopsy (94 vs 26%, p<0.001). Cohort A also had larger tumors (T2 23 vs 5%, p=0.010), higher stage (stage 2 - 24 vs 6%, p=0.002) and higher Adjuvant! mortality estimates above 15% (18 vs 8%, p=0.054). Despite this the use of ACT decreased significantly (20 vs 98%, p<0.001). The majority of patients received adjuvant endocrine treatment (> 90% in both cohorts). Of the 83 patients in cohort A 55 (66%) had low risk RS (0-17), 18 (22%) intermediate risk (18-30) and 10 (12%) high risk RS. ACT was received by 2 of 55 patients with low RS; 6 of 18 patients with intermediate RS and 9 of 10 with high RS. Median follow-up was only 16 months in cohort A vs 74 months in cohort B. 92% of patients in cohort B remain recurrence free. To date only 2 patients in cohort A have recurred, both of which had high RS scores and received ACT.
Conclusion:
In patients with early BC undergoing RS testing at CCSEO we observed a higher proportion of low risk RS as compared to the literature. Additionally, despite larger tumors, higher stage disease and higher Adjuvant! mortality estimates above 15%, the proportion of patients undergoing ACT has significantly decreased since the introduction of RS testing. So far this has not translated into a negative long-term disease outcome although longer follow-up is needed for real-world validation.

Abstract
BACKGROUND This systematic review addresses the question "What is the optimal targeted therapy for female patients with early-stage human epidermal growth factor receptor 2 (her2)-positive breast cancer?" METHODS The medline and embase databases were searched for the period January 2008 to May 2014. The Standards and Guidelines Evidence directory of cancer guidelines and the Web sites of major guideline organizations were also searched. RESULTS Sixty publications relevant to the targeted therapy portion of the systematic review were identified. In four major trials (hera, National Surgical Adjuvant Breast and Bowel Project B-31, North Central Cancer Treatment Group N9831, and Breast Cancer International Research Group 006), adjuvant trastuzumab for 1 year was superior in disease-free survival (dfs) and overall survival (os) to no trastuzumab; trastuzumab showed no benefit in one trial (pacs 04). A shorter duration of trastuzumab (less than 1 year compared with 1 year) was evaluated, with mixed results for dfs: one trial showed superiority (finher), one trial could not demonstrate noninferiority (phare), another trial showed equivalent results (E 2198), and one trial is still ongoing (persephone). Longer trastuzumab duration (hera: 2 years vs. 1 year) showed no improvement in dfs or os and a higher rate of cardiac events. Newer her2-targeted agents (lapatinib, pertuzumab, T-DM1, neratinib) have been or are still being evaluated in both adjuvant and neoadjuvant trials, either by direct comparison with trastuzumab alone or combined with trastuzumab. In the neoadjuvant setting (neoaltto, GeparQuinto, Neosphere), trastuzumab alone or in combination with another anti-her2 agent (lapatinib, pertuzumab) was compared with either lapatinib or pertuzumab alone and showed superior or equivalent rates of pathologic complete response. In the adjuvant setting, lapatinib alone or in combination with trastuzumab, compared with trastuzumab alone (altto) or with placebo (teach), was not superior in dfs. The results of the completed aphinity trial, evaluating the role of dual her2 blockade with trastuzumab and pertuzumab, are highly anticipated. Ongoing trials are evaluating trastuzumab as a single agent without adjuvant chemotherapy (respect) and in patients with low her2 expression (National Surgical Adjuvant Breast and Bowel Project B-47). CONCLUSIONS Taking into consideration disease characteristics and patient preference, 1 year of trastuzumab should be offered to all patients with her2-positive breast cancer who are receiving adjuvant chemotherapy. Cardiac function should be regularly assessed in this patient population.

Abstract
BACKGROUND The Program in Evidence-Based Care (pebc) of Cancer Care Ontario recently created an evidence-based consensus guideline on the systemic treatment of early breast cancer. The evidence for the guideline was compiled using a systematic review to answer the question "What is the optimal systemic therapy for patients with early-stage, operable breast cancer, when patient and disease factors are considered?" The question was addressed in three parts: cytotoxic chemotherapy, endocrine treatment, and human epidermal growth factor receptor 2 (her2)-directed therapy. METHODS For the systematic review, the medline and embase databases were searched for the period January 2008 to May 2014. The Standards and Guidelines Evidence directory of cancer guidelines and the Web sites of major oncology guideline organizations were also searched. The basic search terms were "breast cancer" and "systemic therapy" (chemotherapy, endocrine therapy, targeted agents, ovarian suppression), and results were limited to randomized controlled trials (rcts), guidelines, systematic reviews, and meta-analyses. RESULTS Several hundred documents that met the inclusion criteria were retrieved. The Early Breast Cancer Trialists' Collaborative Group meta-analyses encompassed many of the rcts found. Several additional studies that met the inclusion criteria were retained, as were other guidelines and systematic reviews. Chemotherapy was reviewed mainly in three classes: anti-metabolite-based regimens (for example, cyclophosphamide-methotrexate-5-fluorouracil), anthracyclines, and taxane-based regimens. In general, single-agent chemotherapy is not recommended for the adjuvant treatment of breast cancer in any patient population. Anthracycline-taxane-based polychemotherapy regimens are, overall, considered superior to earlier-generation regimens and have the most significant impact on patient survival outcomes. Regimens with varying anthracycline and taxane doses and schedules are options; in general, paclitaxel given every 3 weeks is inferior. Evidence does not support the use of bevacizumab in the adjuvant setting; other systemic therapy agents such as metformin and vaccines remain investigatory. Adjuvant bisphosphonates for menopausal women will be discussed in later work. CONCLUSIONS The results of this systematic review constitute a comprehensive compilation of the high-level evidence that is the basis for the 2014 pebc guideline on systemic therapy for early breast cancer. Use of cytotoxic chemotherapy is presented here; the results addressing endocrine therapy and her2-targeted treatment, and the final clinical practice recommendations, are published separately in this supplement.

Abstract
The Breast Cancer Disease Site Group of Cancer Care Ontario identified the need for new guidelines for the adjuvant systemic therapy of early-stage breast cancer. The specific question to be addressed was "What is the optimal adjuvant systemic therapy for female patients with early-stage operable breast cancer, when patient and disease factors are considered?" A systematic review was prepared based on literature searches conducted using the medline and embase databases for the period January 2008 to March 5, 2012, and updated to May 12, 2014. Guidelines were located from that search, from the Standards and Guidelines Evidence directory of cancer guidelines, and from the Web sites of major guideline organizations. The literature located was subdivided into the broad categories of chemotherapy, hormonal therapy, and therapy targeted to her2 (human epidermal growth factor receptor 2). Although several of the systemic therapies discussed in this guideline can be considered in the neoadjuvant setting, the review focused on trials with rates of disease-free and overall survival as endpoints and thus excluded several trials that used pathologic complete response as a primary endpoint. Based on the systematic review, the working group drafted recommendations on the use of chemotherapy, hormonal therapy, and targeted therapy; based on their professional experience, they also drafted recommendations on patient and disease characteristics and recurrence risk. The literature review and draft recommendations were circulated to a consensus panel of medical oncologists who had expertise in breast cancer and who represented the regions of Ontario. Items without initial consensus were discussed at an in-person consensus meeting held in Toronto, November 23, 2012. The final recommendations are those for which consensus was reached before or at the meeting. Some of the key evidence was revised after the updated literature search. Evidence reviews for systemic chemotherapy, endocrine therapy, and targeted therapy for her2-positive disease are reported in separate articles in this supplement. The full three-part 1-21 evidence-based series, including complete details of the development and consensus processes, can be found on the Cancer Care Ontario Web site at https://www.cancercare.on.ca/toolbox/qualityguidelines/diseasesite/breast-ebs.

Abstract
Abstract
Purpose:Patients undergoing curative (adjuvant or neoadjuvant) chemotherapy (CT) for breast cancer in the Southeast Ontario Local Heath Integration Network (LHIN) have higher rates of emergency room (ER) visits and hospital admissions (HA) compared to other LHINs in Ontario, Canada. This study is to determine factors associated with ER visits and HA after curative chemotherapy for breast cancer in a tertiary Ontario hospital.
Methods:A retrospective study was conducted of all patients who completed at least one cycle of curative CT for breast cancer at the Cancer Centre for Southeastern Ontario (CCSEO) in 2011 and 2012. We recorded all ER visits and/or HA within 30 days of any cycle of CT. Data collected included demographics, co-morbidities, type and date of surgery, pathologic tumour characteristics (stage, grade and receptor status), type of CT (adjuvant or neoadjuvant) and number of cycles, use and type of granulocyte-colony stimulating factors (G-CSF). We recorded dates and reasons for ER visits, referring patterns to the ER, date of admission and length of stay. Chi-square and t-tests were calculated to determine factors associated with ER visits and HA.
Results:149 patients received curative CT at the CCSEO in 2011 and 2012. Mean age was 58 (range 31-88). 97.3% of patients were female. Comorbidities included hypertension (28.4%), diabetes (10.1%), dyslipidemia (10.1%), coronary artery disease (4.7%) and COPD (2%). Stage distribution was: 4.3% stage 1, 48.6% stage 2 and 36.4% stage 3. 60.8% of patients had grade 3 tumors. 69.8% were ER positive and 61.1% were PR positive. 26.2% were Her2 positive. 62.4% had breast conserving surgery and 56.4% had sentinel lymph node biopsy. Most patients received adjuvant CT (85.2%). The most common CT regimen was FEC-D (89.9%), followed by TC (5.4%) and CMF (4%). 88.6% of patients received G-CSF (either Neupogen or Neulasta) at some point during CT. 53% (n = 79) of patients were seen in the ER at least once within 30 days of CT while 13.4% (n = 20) were admitted to hospital. 36.7% (n = 29) had multiple ER visits. There were a total of 133 ER visits. The most common causes of ER visits were fever without neutropenia (23.3%), pain (13.5%) and febrile neutropenia (9%). Most ER visits occurred on weekdays (74%). We analyzed the following factors associated with ER visits and HA rates: age, gender, comorbidities, TNM staging, grade, receptor status, type of surgery and CT (adjuvant versus neoadjuvant). The only statistically significant factor associated with a higher likelihood of ER visits was stage IIIC breast cancer (p = 0.045). Statistically significant factors associated with HA were tumor size with T2 more likely to be admitted (p = 0.019), adjuvant CT (p = 0.045) and number of CT cycles (p = 0.017).
Conclusions:Over half of all patients receiving curative CT for breast cancer at the CCSEO in 2011 and 2012 visited the ER at least once and more than 1/3 required multiple visits. The only factor associated with ER visits included stage of disease. Factors associated with HA were tumour size, adjuvant CT and number of CT cycles. While most patients received G-CSF at some point during their CT, febrile neutropenia was still the third most common reason for ER visits.

Abstract
OBJECTIVE To identify questions that post-menopausal women with receptor-positive early-stage breast cancer want answered before their adjuvant-endocrine-therapy decision is made. METHODS We surveyed patients eligible for adjuvant-endocrine therapy in the previous 3-18 months. Participants rated the importance of getting each of 95 questions answered before the decision is made (options: essential/desired/not important or no opinion/avoid). For each question rated "essential"/"desired", the participant also identified the purpose(s) for the answer: to help her understand, decide, plan, or other reason(s). RESULTS The response rate was 55% (188/343). Participants rated a mean of 57 (range: 1-95) questions "essential", 80 (range: 1-95) "essential" or "desired", and 2 (range: 0-27) "avoid". Every question was "essential" to ≥31% of participants, and "essential"/"desired" to ≥63%. All but eleven questions were rated as "avoid" by ≥1 participant. The most frequent purposes for "essential" questions were to: understand their situations (mean 45, range: 0-95), decide (mean 18, range: 0-94), and plan (mean 13, range: 0-95). CONCLUSION Many patients want a lot of information before this decision is made but there is wide variation within the group in both the number and in which questions they want answered. PRACTICE IMPLICATIONS Patient education in this setting needs to be tailored to the needs of the individual patient.
