State Variation in the Receipt of a Contralateral Prophylactic Mastectomy Among Women Who Received a Diagnosis of Invasive Unilateral Early-Stage Breast Cancer in the United States, 2004-2012.

ABSTRACT:

Importance

The use of contralateral prophylactic mastectomies (CPMs) among patients with invasive unilateral breast cancer has increased substantially during the past decade in the United States despite the lack of evidence for survival benefit. However, whether this trend varies by state or whether it is correlated with changes in proportions of reconstructive surgery among these patients is unclear.

Objective

To determine state variation in the temporal trend and in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery.

Design, setting, and participants

A retrospective cohort study of 1.2 million women 20 years of age or older diagnosed with invasive unilateral early-stage breast cancer and treated with surgery from Januar
