Breast <strong>Cancer</strong> Outcome Analysis & Compar<strong>at</strong>ive D<strong>at</strong>a Report — 2012<br />

The American College of Surgeons’ Commission on <strong>Cancer</strong> (CoC) <strong>and</strong> N<strong>at</strong>ional Accredit<strong>at</strong>ion Program for<br />

Breast <strong>Center</strong>s (NAPBC) requires annual performance r<strong>at</strong>es to be reported for six quality measures identified by<br />

the NAPBC. Performance <strong>and</strong> outcomes for these measures are evalu<strong>at</strong>ed annually by <strong>Mayo</strong> <strong>Clinic</strong> <strong>Health</strong><br />

System in Eau Claire <strong>and</strong> breast program leadership. Breast cancer d<strong>at</strong>a evalu<strong>at</strong>ed for this report is from the<br />

<strong>Mayo</strong> <strong>Clinic</strong> <strong>Health</strong> System in Eau Claire <strong>Cancer</strong> Registry’s 2011 analytic caseload.<br />

1. Basic epidemiology.<br />

In 2012, it is estim<strong>at</strong>ed th<strong>at</strong> among U.S. women there will be 226,870 new cases of invasive breast cancer<br />

(includes new cases of primary breast cancer among survivors, but not recurrence of original breast cancer<br />

among survivors). Also, there will be 63,300 new cases of in situ breast cancer (includes ductal carcinoma in<br />

situ (DCIS) <strong>and</strong> lobular carcinoma in situ (LCIS), of which about 85 percent will be DCIS. DCIS is a<br />

noninvasive breast cancer, <strong>and</strong> LCIS is a condition th<strong>at</strong> increases the risk of invasive breast cancer. There will<br />

be 39,510 women who die of breast cancer.<br />

2. Local epidemiology as to cases within our group.<br />

Within 2011, <strong>Mayo</strong> <strong>Clinic</strong> <strong>Health</strong> System in Eau Claire diagnosed <strong>and</strong>/or provided first-course tre<strong>at</strong>ments, often<br />

referred to as the analytic caseload to 127 breast p<strong>at</strong>ients per the <strong>Mayo</strong> <strong>Clinic</strong> <strong>Health</strong> System in Eau Claire<br />

<strong>Cancer</strong> Registry. The most commonly used method of disease distribution for studies, <strong>and</strong> in compliance with<br />

n<strong>at</strong>ional guidelines, is the American Joint Committee on <strong>Cancer</strong> (AJCC) staging, the process th<strong>at</strong> describes the<br />

extent or severity of an individual’s cancer based on the extent of the original (primary) <strong>and</strong> the extent of spread<br />

in the body. The 2011 breakdown is as follows:<br />

The stage <strong>at</strong> which the cancer is diagnosed is the best predictor of a woman’s chance of surviving the disease.<br />

Early stage, Stage 0–II requires less aggressive, life-interrupting tre<strong>at</strong>ments to ensure surviving the diagnosis.<br />

Twenty-one cases were Stage 0, 53 cases were Stage I <strong>and</strong> 33 cases were Stage II. Thus, over 80 percent of the
