Background: In 2012, the American Society for Clinical Oncology (ASCO) identified five key opportunities in oncology to improve patient care, recommending against imaging tests for the staging of patients with early breast cancer (EBC) at low risk for metastases. Similarly, the European Society of Medical Oncology (ESMO) guideline does not support radiological staging in asymptomatic EBC (aEBC). The purpose of this study was to assess local practice and outcomes of staging investigations (SIs) in aEBC at the Cancer Centre of Southeastern Ontario (CCSEO). Methods: A retrospective electronic and paper chart review was undertaken to identify all aEBC patients treated at our institution between January 2012 and December 2014. Patients with pathological staging of T1-T2 and N0-1 with any receptor status were included. We collected patient demographics, treatment and pathologic tumor characteristics. The use and outcomes of initial and follow-up SIs were recorded. Data were analyzed to determine associations between the use of SIs and clinical characteristics (chi-square tests, independent samples t-tests and Mann–Whitney U tests). Results: From 2012 to 2014, 295 asymptomatic EBC patients were identified. The mean age was 64, 81% were postmenopausal and 76% had breast conserving surgery. Stage distribution was as follows: stage I 42%, stage IIA 37% and stage IIB 21%. Receptor status was as follows: ER+ 84%, HER2+ 13% and triple negative 12%. Adjuvant chemotherapy was received by 36%, Trastuzumab by 10% and endocrine therapy by 76% of patients. Baseline SIs were performed in 168 patients (57%) for a total of 332 tests. Overt metastatic disease was found in five patients (one bone scan and four CT scans). Seventy-one out of the 168 patients (42%) who received initial staging imaging underwent 138 follow-up imaging tests, none of which were diagnostic for metastases. Nine patients with suspicious CT findings underwent biopsies, of which four were malignant (one metastatic breast cancer and three new primaries). Factors significantly associated with SI were as follows: younger age (p = 0.001), premenopausal status (p = 0.01), T2 stage (p < 0.001), N1 stage (p < 0.001), HER2 positive (p < 0.001), triple negative status (p = 0.007) and use of adjuvant chemotherapy (p < 0.001). Conclusions: Over a 3-year period at our institution, more than 50% of aEBC patients underwent a total of 470 initial and follow-up staging tests, yielding a cancer diagnosis (metastatic breast cancer or second primary cancer) in four patients. We, therefore, conclude that routine-staging investigations in aEBC patients have low diagnostic value, supporting current guidelines that recommend against the routine use of SI in this population.

1016 Background: Tesetaxel, unlike standard taxanes (docetaxel, paclitaxel), is not a substrate for Pgp, a major cause of taxane resistance in tumor models. In a DU4475 breast cancer xenograft that overexpresses Pgp, tesetaxel induced a 94% reduction in tumor size, markedly exceeding the activity of docetaxel (46%) and paclitaxel (26%). Tesetaxel is associated with substantially less neuropathy preclinically than equi-myelotoxic doses of docetaxel. In clinical studies to date, tesetaxel is not associated with hypersensitivity reactions (0% incidence in > 450 patients [pts]), thus eliminating the need for premedication and extended observation. In a prior study, tesetaxel (27-35 mg/m2 Q3 wks) achieved a 38% partial response (PR) rate as 2nd-line therapy in pts with metastatic breast cancer (MBC) who had progressed after multidrug anthracycline-containing regimens. To extend these data, we initiated a phase 2 study of tesetaxel as 1st-line therapy in women with MBC. Methods: Eligibility included MBC; HER2-; ECOG PS 0-1; and adequate organ function. Adjuvant chemotherapy (including taxanes) was allowed. Tesetaxel was administered orally without anti-allergic premedication at a starting dose of 27 mg/m2 once every 3 wks. Overall response rate (ORR; RECIST) was the primary endpoint. Results: All 45 pts have been accrued. Median age is 58 y (range 36-80); median time from diagnosis, 4.0 y (range 0-21); triple negative status, 8 pts at diagnosis, 14 at time of metastasis. Metastatic sites are lung (22 pts), lymph nodes (22), liver (24), and bone (21). Prior treatment includes anti-estrogen therapy (32 pts), adjuvant chemotherapy (31), prior taxane (25), and radiotherapy (28). ORR in 24 pts evaluable for response is 50% (1 CR [4%], 11 PR [46%]); 5 responding pts had prior taxane therapy. Neutropenia is the most common ≥ Grade 3 adverse event with 50% of cases observed after dose escalation to 35 mg/m2; febrile neutropenia and Grade 3 peripheral neuropathy occurred in 2 pts each. There were no hypersensitivity reactions. Conclusions: Tesetaxel is highly active in 1st-line MBC and overcomes multiple limitations of standard taxanes. Updated ORR and PFS for all pts will be presented. Weekly dosing will be evaluated in a new cohort of pts.

Purpose This multicenter, randomized, double-blind, phase II study assessed safety and efficacy of axitinib plus docetaxel in metastatic breast cancer (MBC). Patients and Methods Women with MBC were randomly assigned 2:1 to receive docetaxel 80 mg/m2 once every 3 weeks plus axitinib 5 mg twice per day (combination arm) or placebo (placebo arm), following a lead-in phase I trial. The primary end point was time to progression (TTP). Results In all, 168 patients were enrolled; 112 were randomly assigned to axitinib and 56 to placebo. Median TTP was numerically longer in the combination arm than in the placebo arm (8.1 v 7.1 months), but this difference was not statistically significant (hazard ratio, 1.24; 95% CI, 0.82 to 1.87; one-sided P = .156). The difference in median TTP was greatest among patients who had received prior adjuvant chemotherapy (9.2 v 7.0 months; P = .043, prespecified subgroup analysis). Objective response rate was higher in the combination arm (41.1% v 23.6%; P = .011). The most common grades 3 to 4 treatment-related adverse events (combination/placebo) included diarrhea (10.8%/0%), fatigue (10.8%/5.4%), stomatitis (12.6%/1.8%), mucositis (9.0%/0%), asthenia (7.2%/0%), and hypertension (4.5%/0%). Three patients in the combination arm experienced serious thromboembolic events (one death). Febrile neutropenia was more frequent in the combination arm (15.3% v 7.1%); rates of other hematologic toxicities were comparable. Increased toxicity with axitinib was generally managed by dose reduction and/or growth factor support. Conclusion The addition of axitinib to docetaxel did not improve TTP in first-line MBC treatment. Combination therapy may be more effective in patients previously exposed to adjuvant chemotherapy.

PURPOSE The National Cancer Institute of Canada-Clinical Trials Group (NCIC-CTG) conducted a phase II study to assess the efficacy and toxicity of docetaxel as first-line chemotherapy in metastatic breast cancer (MBC). PATIENTS AND METHODS Fifty-one patients with measurable MBC were studied. Three patients were ineligible and were excluded from analysis. The planned dose of docetaxel was 100 mg/m2 intravenously (i.v.) every 3 weeks. Prior adjuvant chemotherapy was allowed if at least 12 months had elapsed from completion of treatment to recurrence. RESULTS The most severe toxicity was granulocytopenia. Ten patients (20.8%) were hospitalized for febrile neutropenia. The protocol was amended to a starting dose of 75 mg/m2 for the last 16 patients. Sixty percent of patients experienced hypersensitivity reactions (HSRs). After two protocol amendments, the use of a premedication regimen of oral dexamethasone and i.v. H1 and H2 blockers prevented significant HSRs. Edema developed in 62% of patients and was cumulative, was present in 50% who received greater than 400 mg/m2, and was not improved by premedication regimens. Following an independent radiology review, 22 partial remissions and four complete responses in 47 assessable patients were confirmed (response rate, 55%; 95% confidence interval [CI], 40% to 69%). The response rate for 15 assessable patients registered at 75 mg/m2 was 40% (95% CI, 16% to 67%); for 32 assessable patients registered at 100 mg/m2, the response rate was 63%, (95% CI, 43% to 78%). CONCLUSION Docetaxel is an active agent in MBC. Its activity as a single agent is comparable to many combination chemotherapy regimens and is not affected by prior adjuvant chemotherapy. Studies are ongoing to improve its therapeutic index and to incorporate docetaxel in combination chemotherapy regimens.
