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 .

Purpose The American Society of Clinical Oncology (ASCO) has policies and procedures for endorsing practice guidelines that have been developed by other professional organizations. Methods The Cancer Care Ontario (CCO) Guideline on Adjuvant Ovarian Ablation (OA) in the Treatment of Premenopausal Women With Early-Stage Invasive Breast Cancer was reviewed for developmental rigor by methodologists. An ad hoc review panel of experts reviewed the content. Results The ASCO ad hoc OA guideline review panel concurred that the recommendations are clear, thorough, based on the most relevant scientific evidence in this content area, and present options that will be acceptable to patients. According to the CCO guideline: one, OA should not be routinely added to systemic therapy with chemotherapy, tamoxifen, or the combination of tamoxifen and chemotherapy; two, OA alone is not recommended as an alternative to any other form of systemic therapy, except in the specific case of patients who are candidates for other forms of systemic therapy but who, for some reason, will not receive any other systemic therapy (eg, patients who cannot tolerate other forms of systemic therapy or patients who choose no other form of systemic therapy); and three, when chemical suppression using luteinizing hormone–releasing hormone agonists is the chosen method of OA, in the opinion of the Breast Cancer Disease Site Group, monthly injection is the recommended mode of administration. The mode of administration in nearly all of the available trials has been monthly administration. Conclusion The ASCO review panel agrees with the recommendations as stated in the CCO guideline, with the qualification that ongoing research studies may alter the recommendations of the panel.

Purpose An American Society of Clinical Oncology (ASCO) panel considered the Cancer Care Ontario (CCO) recommendations on the role of patient and disease factors in selecting adjuvant therapy for women with early-stage breast cancer for endorsement. Methods ASCO staff reviewed the CCO guideline for methodologic rigor, and an ASCO panel of content experts reviewed the content of the recommendations. CCO Recommendations For making decisions regarding adjuvant therapy, nodal status, tumor size, estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2) status, tumor grade, and lymphovascular invasion are relevant; Oncotype DX score and Adjuvant! Online may be used as risk stratification tools; and age, menopausal status, and medical comorbidities should be considered. Chemotherapy should be considered for patients with positive lymph nodes, ER-negative disease, HER2-positive disease, Adjuvant! Online mortality greater than 10%, grade 3 lymph node–negative tumors (T > 5 mm), triple-negative (ER-negative, PgR-negative, HER2-negative) tumors, lymphovascular invasion positivity, or estimated distant relapse risk of greater than 15% at 10 years based on Oncotype DX recurrence score (RS). Chemotherapy may not be beneficial or required for small node-negative tumors (T < 5 mm) without high-risk features or for patients with HER2-negative, strongly ER-positive, and PgR-positive cancer with micrometastatic nodal disease, T less than 5 mm, or Oncotype DX RS with an estimated distant relapse risk of less than 15% at 10 years. ASCO Panel Conclusion The ASCO panel endorses the recommendations with minor suggested revisions and highlights three areas that warrant further consideration: tumor histology and adjuvant therapy recommendations, risk stratification tools and proposed Oncotype DX RS thresholds to guide decisions about chemotherapy, and patient factors in decision making.
