* Tumor biopsy for testing/research at baseline and Cycle 1 Day 15
* Cycle 0 is 28 days of anastrozole PO daily and, if premenopausal, goserelin SC every 28 days.
* Cycles 1-5: PD 0332991 combined with anastrozole (and goserelin if premenopausal) is to be (4) 28-day cycles followed by a 5th cycle of 10-12 days duration consisting of daily PD 0332991 and anastrozole (last dose day before surgery)
* Standard surgery will be performed per institutional standards 2-4 weeks following the completion of Cycle 4 in those who did not receive Cycle 5. In patients who receive Cycle 5, surgery occurs on Day 11, 12, or 13 of Cycle 5.
* Patients who derived benefit from the therapy have the option of taking PD 0332991 in combination with endocrine therapy for 23 cycles after surgery and adjuvant chemotherapy and radiation if indicated. It should be re-started at least 4 weeks after the completion of chemotherapy and radiation therapy if these treatments were planned.

Tumor biopsy

Cynthia X Ma, M.D., Ph.D.

A Phase II study to investigate the potential utility of PD 0332991 in the treatment of early stage ER+ Human epidermal growth factor receptor 2 (HER2)- breast cancer, to investigate whether the combination of PD 0332991 and anastrozole is able to: 1) improve the pathologic complete response rate when compared to the historical control of single agent aromatase inhibitors, 2) result in fewer patients with on therapy Ki67\>10% compared to historical control.

PD 0332991 and Anastrozole for Stage 2 or 3 Estrogen Receptor Positive and HER2 Negative Breast Cancer

A Phase II Trial of Neoadjuvant PD 0332991, a Cyclin-Dependent Kinase (Cdk) 4/6 Inhibitor, in Combination With Anastrozole in Women With Clinical Stage 2 or 3 Estrogen Receptor Positive and HER2 Negative Breast Cancer

Complete cell cycle arrest is defined as Ki67 ≤ 2.7% following 2 weeks of neoadjuvant PD 0332991

Compare rate of complete cell cycle arrest (defined as Ki67 ≤ 2.7%) arrest between C1D1 and C1D15

* The clinical response rate is the number of patients whose disease meets the WHO criteria of complete or partial response prior to surgery divided by the total number of eligible patients who began combination neoadjuvant treatment.
* Complete Response (CR) is defined as the disappearance of all known disease based on a comparison between the pre-treatment measurements and the measurements taken at the completion of neo-adjuvant therapy (that is, at the end of cycle 4 neo-adjuvant combination therapy). In addition there is no appearance of new lesions.
* Partial Response (PR) is defined as a 50% or greater decrease in the product of the bidimensional measurements of the lesion (total tumor size) between the pre-treatment measurements and the measurements taken at the completion of neo-adjuvant therapy (that is, at the end of cycle 4 neo-adjuvant combination therapy). In addition there can be no appearance of new lesions or progression of any lesion.

* The radiological response rate is the number of patients whose disease meets with WHO criteria for complete or partial response at the evaluation prior to surgery divided by the total number of eligible patients who began combination neo-adjuvant therapy.
* Complete Response (CR) is defined as the disappearance of all known disease based on a comparison between the pre-treatment measurements and the measurements taken at the completion of neo-adjuvant therapy (that is, at the end of cycle 4 neo-adjuvant combination therapy). In addition there is no appearance of new lesions.
* Partial Response (PR) is defined as a 50% or greater decrease in the product of the bidimensional measurements of the lesion (total tumor size) between the pre-treatment measurements and the measurements taken at the completion of neo-adjuvant therapy (that is, at the end of cycle 4 neo-adjuvant combination therapy). In addition there can be no appearance of new lesions or progression of any lesion.

The maximum grade for each type of adverse event will be recorded for each patient using the NCI-CTCAE v4.0 coding scheme, and frequency tables will be reviewed to determine patterns. Additionally, the relationship (possibly related, probably related, and definitely related) of the adverse event(s) to the study treatment will be taken into consideration.

* Preoperative endocrine prognostic index (PEPI) score is derived from four factors assigned a numerical score following neoadjuvant endocrine therapy, including Ki67 expression in the surgical specimen, pathologic tumor size (indicated as "T" below), lymph node status (indicated as "N" below), and estrogen receptor (ER) level (indicated as ER Allred below).
* PEPI-0 score indicates T1 or T2, N0, Ki67 \< 2.7%, ER Allred \> 2.
* It predicts a low risk of recurrence.

To assess Ki67 level on serially collected tumor specimens

-A pathologic complete response is defined as no histology evidence of invasive tumor cells in the surgical breast specimen and sentinel or axillary lymph nodes.

Local recurrence is defined as histologic evidence of ductal carcinoma in situ or invasive breast cancer in the ipsilateral breast or chest wall.

Regional recurrence is defined as the cytologic or histologic evidence of disease in the ipsilateral internal mammary, ipsilateral supraclavicular, ipsilateral infraclavicular and/or ipsilateral axillary nodes or soft tissue of the ipsilateral axilla.

Distant recurrence is defined as the cytologic, histologic, and/or radiographic evidence of disease in the skin, subcutaneous tissue, lymph nodes (other than local or regional metastasis), lung, bone narrow, central nervous system or histologic and/or radiographic evidence of skeletal or liver metastasis.

Second primary breast cancer is defined histologic evidence of ductal carcinoma in situ or invasive breast cancer in the contralateral breast or chest wall.

Second primary cancer (non-breast) is defined as any non-breast second primary cancer other than squamous or basal cell carcinoma of the skin, melanoma in situ, or carcinoma in situ of the cervix is to be reported and should be confirmed histologically whenever possible.
