Anastrozole Adjuvant Trial - Study of Anastrozole Compared to NOLVADEX (Tamoxifen Citrate) for Adjuvant Treatment of Early Breast Cancer (Clinical Studies), Tamoxifen Citrate Was Added to Adjunct Cytotoxic Chemotherapy- Treatment of Malignant Joint Tumor. (NASBP-B-09)
At a median follow-up of 33 months, the combination of anastrozole and NOLVADEX (tamoxifen citrate) did not demonstrate any efficacy benefit when compared to NOLVADEX (tamoxifen citrate) therapy given alone in all patients as well as in the hormone receptor positive subpopulation. This treatment arm was discontinued from the trial. This study is now a combination therapy whereas the median duration of adjuvant treatment for safety evaluation is 59.8 months and 59.6 months for patients receiving anastrozole 1 mg and NOLVADEX (tamoxifen citrate) 20 mg, respectively.

Primary outcomes
- The combination of anastrozole and NOLVADEX (tamoxifen citrate)was added to adjunct cytotoxic chemothrapy — At a median follow-up of 33 months
Among women with ER positive or unknown breast cancer and positive nodes who received about 5 years of treatment, overall survival at 10 years was 61.4% for NOLVADEX (tamoxifen citrate) vs. 50.5% for control (logrank 2p \< 0.00001). The recurrence-free rate at 10 years was 59.7% for NOLVADEX (tamoxifen citrate) vs. 44.5% for control (logrank 2p \< 0.00001). Among women with ER positive or unknown breast cancer and negative nodes who received about 5 years of treatment, overall survival at 10 years was 78.9% for NOLVADEX (tamoxifen citrate) vs. 73.3% for control (logrank 2p \< 0.00001). The recurrence-free rate at 10 years was 79.2% for NOLVADEX (tamoxifen citrate) versus 64.3% for control (logrank 2p \< 0.00001) - female, effective clinical care — 33 months
Breast Cancer Resection Pathology Reporting: pT Category (Primary Tumor) and pN Category (Regional Lymph Nodes) with Histologic Grade: Percentage of breast cancer resection pathology reports that include the pT category (primary tumor), the pN category (regional lymph nodes), and the histologic grade - female, effective clinical care — 12-month
Receptor/Progesterone Receptor (ER/PR) Positive Breast Cancer: Percentage of female patients aged 18 years and older with Stage IC through IIIC, ER or PR positive breast cancer who were prescribed tamoxifen or aromatase inhibitor (AI) during the 12-month reporting period \*Although there a newer version of this measure is available (CMS140v2), a substantive error was discovered in the June 2013 version of this electronically specified clinical quality measure. The PQRS will require the use of the prior, December 2012 version of this measure, which is CMS140v1.
