Inflammatory and other breast cancer incidence rate trends by estrogen receptor status in the Surveillance, Epidemiology, and End Results database (2001-2015).

ABSTRACT:

Purpose

Inflammatory breast cancer (IBC) rates increased in the United States before the turn of the twenty-first century. We examine trends by estrogen receptor (ER) status since then.

Methods

Using data from the Surveillance, Epidemiology, and End Results (SEER) program for years 2001-2015, we calculated age-adjusted incidence rates for IBC (defined by AJCC TNM category T4d, extent of disease codes, and morphology code 8530) by ER status, which was imputed if unknown, among women aged 25-84 years. For comparison, we included other locally advanced breast cancer and other breast cancers partitioned into localized and regional/distant/unstaged. We fit joinpoint log-linear models to annual rates to calculate annual percentage change (APC) and average annual percentage change
