Evidence Based Treatment

<b><i>Background:</i></b> In order to offer optimal treatment approaches based on available evidence, the Commission Breast of the Working Group Gynecologic Oncology (AGO) of the German Cancer Society developed therapy algorithms for eight complex treatment situations in primary and advanced breast cancer. <b><i>Summary:</i></b> Therapy algorithms for the following complex treatment situations are outlined in this paper: (neo)adjuvant therapy of human epidermal growth factor receptor 2 (HER2)-positive breast cancer; axillary surgery and neoadjuvant chemotherapy; adjuvant endocrine therapy in premenopausal patients; adjuvant endocrine therapy in postmenopausal patients; hormone receptor (HR)-positive/HER2-negative metastatic breast cancer: strategies; HR-positive/HER2-negative metastatic breast cancer: endocrine-based first-line treatment; HER2-positive metastatic breast cancer: first to third-line; metastatic triple-negative breast cancer. <b><i>Key Messages:</i></b> The therapy options shown in these algorithms are based on the current AGO recommendations updated in January 2020 but cannot represent all evidence-based treatment options. Prior therapies, performance status, comorbidities, patient preference, etc. must be taken into account for the actual treatment choice. Therefore, in individual cases, other evidence-based treatment options not listed here may also be appropriate and justified.

Since its introduction more than 30 years ago, tamoxifen has been the most widely used endocrine therapy for the treatment of women with advanced breast cancer. More recently, a number of alternative endocrine treatments have been developed, including several selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs) and, most recently, fulvestrant ('Faslodex'). Fulvestrant is an estrogen receptor (ER) antagonist, which, unlike the SERMs, has no known agonist (estrogenic) effect and downregulates the ER protein. Tamoxifen is effective and well tolerated, although the non-steroidal AIs, anastrozole and letrozole, are more effective treatments for advanced disease than tamoxifen. Fulvestrant has recently gained US Food and Drug Administration approval for the treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following antiestrogen therapy. In two global phase III clinical trials fulvestrant was at least as effective and as equally well tolerated as anastrozole for the treatment of postmenopausal women with advanced and metastatic breast cancer. In a retrospective analysis of the combined data from these trials, mean duration of response was significantly greater for fulvestrant compared with anastrozole. These new hormonal treatments expand the choice of endocrine therapy for women with advanced breast cancer and offer new options for sequencing and combining treatments.

AbstractTherapy options shown in the algorithms are based on the current AGO recommendations, but cannot represent all evidence-based treatment options, since prior therapies, performance status, comorbidities, patient preference, etc. must be taken into account for the actual treatment choice. In individual cases, other evidence-based treatment options may also be appropriate and justified. Regardless of approval status, the algorithms only take into account drugs that were available in Germany at the time the algorithm was last updated. Here we present the 2021 update of AGO treatment algorithms for early and metastatic breast cancer, which are intended to intensify structured treatment decision by providing reproducible and evidence-based treatment paths and may be helpful for a broad treatment landscape.

1073 Background: Endocrine therapy is a key modality in the management of estrogen receptor positive metastatic breast cancer. Fulvestrant (ICI 182,780) is an estrogen receptor downregulator. It has previously been shown to be as effective as anastrozole in patients who had previously progressed on tamoxifen. Methods: A retrospective study was carried out of metastatic breast cancer patients treated at Charing Cross Hospital between 2002–2005 who had received fulvestrant following treatment failure with tamoxifen and a third generation aromatase inhibitor. All patients were postmenopausal and received fulvestrant 250mg IM every 28 days. Measurable disease was assessed by response evaluation criteria in solid tumors (RECIST). Results: A total of 45 patients were identified with a median age of 60 (range 36 to 90). The ER status was known in 95% (n=43) of patients and was positive in all cases, it was unknown in 2% (n=2). At the time of commencing fulvestrant, 96% (n=43) had metastatic disease and 4% (n=2) locally advanced disease. All patients had received at least 2 lines of prior endocrine therapy (including adjuvant therapy), at time of starting fulvestrant the median number of prior regimens was 3 (range 3–5). Fulvestrant was administered for a median of 4 months (range 1 to 20 months), with 4 patients currently still receiving therapy as of 1 November 2006. Of the 45 patients, 2.2% (n=1) achieved a partial response, while 31% (n=14) achieved stable disease for at least 6 months. Thus, 33.3% (n=15) obtained clinical benefit (defined as PR or SD for at least 6 months). The response rates based on line of therapy will be presented. Of the 45 patients, 41 were evaluable for survival data. The median survival of the remaining patients from the start of fulvestrant therapy was 9 months (range 1 to 48 months). Of the 44 patients, 14% (n=6) remain alive. The treatment was well tolerated and toxicity data will be presented. Conclusions: Fulvestrant is well tolerated and is efficacious as treatment for advanced breast cancer that has failed tamoxifen and a third generation aromatase inhibitors. No significant financial relationships to disclose.
