PURPOSE To update the American Society of Clinical Oncology endorsement of the Cancer Care Ontario recommendations on the Role of Patient and Disease Factors in Adjuvant Systemic Therapy Decision Making for Early-Stage, Operable Breast Cancer. METHODS Two phase III trials—the Trial Assigning Individualized Options for Treatment (TAILORx) in women with hormone receptor–positive, node-negative tumors and the Microarray in Node-Negative and 1 to 3 Positive Lymph Node Disease May Avoid Chemotherapy (MINDACT) trial—provided the evidence for this update. UPDATED RECOMMENDATIONS Shared decision making between clinicians and patients is appropriate for adjuvant systemic therapy for breast cancer. For patients older than age 50 years and whose tumors have Onco type DX recurrence scores less than 26, and for patients age 50 years or younger whose tumors have Onco type DX recurrence scores less than 16, there is little to no benefit from chemotherapy. Clinicians may offer endocrine therapy alone for these patients. For patients age 50 years or younger with recurrence scores of 16 to 25, clinicians may offer chemoendocrine therapy. Patients with recurrence scores greater than 30 should be considered candidates for chemoendocrine therapy. Based on informal consensus, the Panel recommends that oncologists may offer chemoendocrine therapy to patients with Onco type DX scores of 26 to 30. The MammaPrint assay could be used to guide decisions on withholding adjuvant systemic chemotherapy in patients with hormone receptor–positive lymph node–negative breast cancer and in select patients with lymph node–positive cancers. In both patients with node-positive and node-negative disease, evidence of clinical utility of the MammaPrint assay was only apparent in those determined to be at high clinical risk; the Panel thus did not recommend use of MammaPrint assay in patients determined to be at low clinical risk. Remaining recommendations from the 2016 ASCO guideline endorsement are unchanged. Additional information is available at www.asco.org/breast-cancer-guidelines .

185 Background: A second medical oncology opinion (SMO) may facilitate chemotherapy decision-making. However, little is known about the interplay between SMOs, treatment decision-making and chemotherapy use. Methods: We surveyed women newly diagnosed with early-stage invasive breast cancer and treated in 2013-2014 (response rate 70%), accrued approximately 3 months after surgery through 2 population-based SEER registries (Georgia and Los Angeles), about their experiences with medical oncologists, decision-making, and chemotherapy use. We evaluated demographic, clinical and decisional factors associated with SMO using logistic regression, and evaluated the association between SMO and chemotherapy, adjusting for clinical indication for chemotherapy, results of the 21-gene recurrence score assay, and estimated propensity for SMO given patient and tumor-specific characteristics. Results: Among 1182 insured patients who consulted any medical oncologist, 8.7% had SMO and 2.4% received chemotherapy from the SMO provider. On multivariable analysis, predictors of SMO use were younger age (odds ratio, OR 0.97 per year, 95% confidence interval, CI 0.94-0.99), education (college vs. high school graduate, OR 1.88, CI 1.06-3.33), an intermediate 21-gene recurrence score (OR 2.21, CI 1.18-4.16) and a variant of uncertain significance on BRCA1/2 gene testing (OR 5.61, CI 1.22-25.72). Satisfaction with chemotherapy decision-making was high and did not differ between patients who did vs. did not receive SMO (85.3% quite or totally satisfied vs. 86%, p-value 0.85). On multivariable analysis, chemotherapy use did not differ between SMO recipients vs. non-recipients (p-value 0.25). Conclusions: SMO use was low among early-stage breast cancer patients, and was not followed by more or less receipt of chemotherapy. High decision satisfaction regardless of SMO use suggests little unmet demand. Along with younger age and more education, the factor that predicted SMO use was uncertain results of genomic testing. Studies of precision medicine should track patients’ demand for SMO, which may rise with the dissemination of increasingly complex genomic tests. Funding: P01-CA-163233
