Current NCI-sponsored Cooperative Group trials of endocrine therapies in breast cancer

Abstract: Over several decades, investigators working through National Cancer Institutesponsored Cooperative Groups have contributed to major advances in the endocrine treatment of breast cancer. Accomplishments include the benefit of tamoxifen therapy for early stage invasive and noninvasive breast cancer, the benefit of raloxifene and tamoxifen for prevention of breast cancer, the improved efficacy of tamoxifen after chemotherapy as opposed to concurrent administration, and the ability of letrozole administered after … Show more

“…Similar to that experience, the CCOP network facilitated the completion of studies in the development of OncoType DX, a genotype scoring system that evaluates patients' risk of cancer recurrence. Specimens and data from previous trials were used to develop and validate OncoType DX,48 and an ongoing NCI trial (Program for the Assessment of Clinical Cancer Tests or PACCT‐1)49 will evaluate the need for chemotherapy in hormone‐responsive patients who have OncoType DX scores that are difficult to interpret. For physicians and patients who are considering treatment, the findings from that study will better inform their balancing of the risk of recurrence with other considerations and whether the prospective chemotherapy treatment benefits will justify the risks 50.…”

“…Unfortunately, very few genomic biomarkers have made the transition from the laboratory to the clinic, but those that have either cleared the hurdle of clinical validation or are being considered in large-scale clinical trials to establish their clinical validity are promising (Slodkowska and Ross 2009;Straver et al 2010;Ross et al 2008;Cardoso et al 2007;Mook et al 2007;Mamounas et al 2008;Marchionni et al 2007;Eng-Wong and Zujewski 2008;Habel et al 2006).
