Breast Cancer (Invasive; Nonmetastatic) Treatment Regimens |
|
Clinical Trials: The NCCN recommends cancer patient participation in clinical trials as the gold standard for treatment. |
|
Cancer therapy selection, dosing, administration, and the management of related adverse events can be a complex process that should be handled by an experienced healthcare team. Clinicians must choose and verify treatment options based on the individual patient; drug dose modifications and supportive care interventions should be administered accordingly. The cancer treatment regimens below may include both U.S. Food and Drug Administration-approved and unapproved indications/regimens. These regimens are only provided to supplement the latest treatment strategies. These Guidelines are a work in progress that may be refined as often as new significant data becomes available. The National Comprehensive Cancer Network Guidelines® are a consensus statement of its authors regarding their views of currently accepted approaches to treatment. Any clinician seeking to apply or consult any NCCN Guidelines® is expected to use independent medical judgment in the context of individual clinical circumstances to determine any patient’s care or treatment. The NCCN makes no warranties of any kind whatsoever regarding their content, use, or application and disclaims any responsibility for their application or use in any way. |

a If patient is not postmenopausal, sequential evaluation of hormonal status is recommended to consider an alternative endocrine agent. b Some SSRIs like fluoxetine and paroxetine decrease the formation of impact its efficacy. Caution is advised about coadministration of these drugs with tamoxifen. However, citalopram and venlafaxine appear to have minimal impact on tamoxifen metabolism. At this time, based on current data the panel recommends against CYP2D6 gene testing for women being considered for tamoxifen therapy. Coadministration of strong inhibitors of CYP2D6 should be used with caution. c A balanced discussion of the risk and benefits associated with ovarian suppression therapy is critical. Aromatase inhibitor or tamoxifen for 5 years plus ovarian suppression should be considered, based on SOFT and TEXT clinical trial outcomes, for premenopausal women at higher risk of recurrence (ie, young age, high-grade tumor, lymph node involvement). d The three selective aromatase inhibitors (ie, anastrozole, letrozole, exemestane) have shown similar anti-tumor efficacy and toxicity profiles in randomized studies in the adjuvant and preoperative settings. The optimal duration of aromatase inhibitors in adjuvant therapy is uncertain. e Retrospective evidence suggests that anthracycline-based chemotherapy regimens may be superior to nonanthracycline-based regimens in patients with HER2-positive tumors. f Randomized clinical trials demonstrate that the addition of a taxane to anthracycline-based chemotherapy provides an improved outcome. g CMF and radiation therapy may be given concurrently, or the CMF may be given first. All other chemotherapy regimens should be given prior to radiotherapy. h Chemotherapy and endocrine therapy used as adjuvant therapy should be given sequentially with endocrine therapy following chemotherapy. i Nab-paclitaxel may be substituted for paclitaxel or docetaxel due to medical necessity (ie, hypersensitivity reaction). If substituted for weekly paclitaxel or docetaxel, then the weekly dose of nab-paclitaxel should not exceed 125mg/m2. j Consider scalp cooling to reduce incidence of chemotherapy-induced alopecia for patients receiving neoadjuvant/adjuvant chemotherapy. Results may be less effective with anthracycline- containing regimens. k It would be acceptable to change the administration sequence to paclitaxel followed by dose-dense AC. l All cycles are with myeloid growth factor. m Trastuzumab and hyaluronidase-oysk injection for subcutaneous use may be substituted for trastuzumab.52,53 It has different dosing and administration instructions compared to intravenous trastuzumab. Do not substitute trastuzumab and hyaluronidase-oysk for or with ado-trastuzumab emtansine. (Trastuzumab and hyaluronidase-oysk 600mg subcutaneous over 2-5 minutes. Cycle length is regimen specific. Trastuzumab and hyalruonidase-oysk is administered as a substitute for intravenous trastuzumab on the days that intravenous trastuzumab is administered as per the regimen. This agent dose not require a loading dose. No dose adjustments for patient body weight or for different concomitant chemotherapy are required). An FDA-approved biosimilar is an appropriate substitute for trastuzumab. n Pertuzumab, trastuzumab, and hyaluronidase-zzxf injection for subcutaneous use may be substituted anywhere that the combination of intravenous pertuzumab and intravenous trastuzumab are given as part of systemic therapy. Pertuzumab, trastuzumab, and hyaluronidase-zzxf injection for subcutaneous use has different dosing and administration instructions compared to the intravenous product. o If no residual disease after preoperative therapy or no preoperative therapy: Complete up to one year of HER2-targeted therapy with trastuzumab (Category 1) +/- pertuzumab. Consider extended neratinib (Neratinib 240mg orally once daily for 1 year) following adjuvant trastuzumab-containing therapy for patients with hormone receptor-positive, HER2-positive disease with a perceived high risk of recurrence.54,55 The benefit or toxicities associated with extended neratinib in patients who have received pertuzumab or ado-trastuzumab emtansine is unknown. p If residual disease after preoperative therapy: Ado-trastuzumab emtansine alone (Category 1; Ado-trastuzumab emtansine 3.6mg/kg IV every 21 days for 14 cycles. If ado-trastuzumab emtansine discontinued for toxicity, then trastuzumab (Category 1) +/- pertuzumab to complete one year of therapy.56,57 Consider extended neratinib (Neratinib 240mg orally once daily for 1 year) following adjuvant trastuzumab-containing therapy for patients with hormone receptor-positive, HER2-positive disease with a perceived high risk of recurrence.54,55 The benefit or toxicities associated with extended neratinib in patients who have received pertuzumab or ado-trastuzumab emtansine is unknown. q Trastuzumab given in combination with an anthracycline is associated with significant cardiac toxicity. Concurrent use of trastuzumab and pertuzumab with an anthracycline should be avoided. r Evaluate left ventricular ejection fraction (LVEF) before and during treatment. The optimal frequency of LVEF assessment during adjuvant trastuzumab therapy is not known, The FDA label recommends LVEF measurements prior to initiation of trastuzumab and every 3 months during therapy. s Paclitaxel + trastuzumab may be considered for patients with low-risk, T1, N0, M0, HER2-positive disease, particularly those not eligible for other standard adjuvant regimens due to comorbidities. |
