Measure
Palbociclib + Letrozole or + Fulvestrant
* Palbociclib should be taken by mouth with food on a 5 days on/2 days off schedule (meaning: on Days 1-5, 8-12, 15-19, and 22-26 of each 28-day cycle). * Patients who are receiving letrozole will take it daily by mouth, every day of each 28-day cycle. * Patients who are receiving fulvestrant will receive it as two intramuscular injections (one into each buttock) on Days 1 and 15 of Cycle 1 and then on Day 1 of each cycle thereafter. * Goserelin is given as a subcutaneous injection every 28 days. It is preferred to be given on Day 1 of each cycle, but it may be administered on any day of the treatment cycle to accommodate its specific Q28-day cycle. It will be given to pre- or peri-menopausal women only. * Optional research biopsy at baseline and progression * Blood for research at baseline, cycle 1 day 15, cycle 2 day 1, every 2-3 months (to coincide with imaging studies), and time of progression

PRIMARY outcome

Timeframe: Through the first 29 days of treatment

Population: The following participants were not evaluable for this outcome measure: 4 participants did not take palbociclib dose as per protocol and were without dose-limiting toxicity; 2 participants withdrew in cycle 1, and 1 participant went off treatment in cycle 1 due to adverse events unrelated to the study.

* The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting. * Grade 3 neutropenia: \<1000-500/mm\^3; \<1.0-0.5 x 10e9/L * Grade 4 neutropenia: \<500/mm\^3; \<0.5 x 10e9/L

SECONDARY outcome

Timeframe: 1 year

* PFS will be followed from start of treatment to time of progression or death, whichever occurs first. * Progressive disease: At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).
