Abstract

Background: The objective of this study was to compare postoperative complication rates and healthcare charges between patients who underwent coordinated versus staged breast surgery and bilateral salpingo-oophorectomy (BSO).

Patients And Methods: The MarketScan administrative database was used to identify adult female patients with invasive breast cancer or BRCA1/BRCA2 mutations who underwent BSO and breast surgery (lumpectomy or mastectomy with or without reconstruction) between 2010 and 2015. Patients were assigned to the coordinated group if a breast operation and BSO were performed simultaneously or assigned to the staged group if BSO was performed separately. Primary outcomes were (1) incidence of 90-day postoperative complications and (2) 2-year aggregate perioperative healthcare charges. Fisher's exact tests, Wilcoxon rank-sum tests, and multivariable regression analyses were performed.

Results: Of the 4228 patients who underwent breast surgery and BSO, 412 (9.7%) were in the coordinated group and 3816 (90.3%) were in the staged group. The coordinated group had a higher incidence of postoperative complications (24.0% vs. 17.7%, p < 0.01), higher risk-adjusted odds of postoperative complications [odds ratio (OR) 1.37, 95% confidence interval (CI) 1.06-1.76, p = 0.02], and similar aggregate healthcare charges before (median charges: $106,500 vs. $101,555, p = 0.96) and after risk-adjustment [incidence rate ratio (IRR) 1.00, 95% CI 0.93-1.07; p = 0.95]. In a subgroup analysis, incidence of postoperative complications (12.9% for coordinated operations vs. 11.7% for staged operation, p = 0.73) was similar in patients whose breast operation was a lumpectomy.

Conclusions: While costs were similar, coordinating breast surgery with BSO was associated with more complications in patients who underwent mastectomy, but not in patients who underwent lumpectomy. These data should inform shared decision-making in high-risk patients.
