BACKGROUND: Few large-scale multicenter studies have examined wait times for breast surgery and no benchmarks exist.
METHODS: Using the National Cancer Data Base, we analyzed time from diagnosis to first surgery for 819,175 non-neoadjuvant AJCC stage 0-III breast cancer patients treated from 2003 to 2011. Chi-square tests and logistic regression models were used to examine factors associated with delays to surgery and adjuvant chemotherapy.
RESULTS: Seventy percent of patients underwent an initial lumpectomy (LP), 22% a mastectomy (MA), and 8% a mastectomy with reconstruction (MR). The median time from diagnosis to first surgery significantly increased by approximately 1 week for all three procedures over the study period. In a multivariate analysis, the following variables were independent predictors of a longer wait time to first surgery: increasing age, black or Hispanic race, Medicaid or no insurance, low-education communities and metropolitan areas, increasing comorbidities, stage 0 and grade 1 disease, academic/research facilities, high-volume facilities, and facilities located in the New England, Mid-Atlantic, and Pacific regions. In 2010-2011, patients who waited >30 days for surgery were 1.36 times more likely (OR = 1.36, 95% CI 1.30-1.43) to experience a delay to adjuvant chemotherapy >60 days compared with patients who were surgically treated within 30 days of diagnosis.
CONCLUSIONS: Facility and socioeconomic factors are most strongly associated with longer wait times for breast operations, and delays to surgery are associated with delays to adjuvant chemotherapy initiation.
