Evolving Trends and Influencing Factors in Mastectomy Decisions.
It is known that survival is unaffected by the choice of surgical management for breast cancer (BC) patients. Despite this fact, recent literature reveals that the number of bilateral mastectomies (BMs) in the United States is increasing. In an effort to elucidate potential factors influencing this trend, we investigated socioeconomic and clinicopathologic characteristics of our patient cohort that could have affected a patient's decision between unilateral mastectomy (UM) versus BM. Five-hundred-eight patients with unilateral BC who underwent mastectomy between 2000 and 2009 were analyzed: 397-UM; 111-BM. Influence of patient's age, insurance status, residence (rural versus urban), subsequent reconstruction, marital status, smoking history, family cancer history, cancer stage and grade on the BM versus UM patient's decision were analyzed using independent sample t tests, χ2 and logistic regression analysis. BM was more likely to be chosen by younger (<50 years) patients (P < 0.001); patients with private insurance [odds ratio (OR) = 2.22, 95% confidence interval (CI) = 1.4-3.5]; residence in urban settings (OR = 5.09, 95% CI = 2.5-10.4); and plans for subsequent reconstruction (OR = 2.31, 95% CI = 1.4-3.8). Marital status, smoking history, family cancer history, BC stage and grade did not significantly impact patient's choice of BM versus UM. We found that patients with unilateral BC who are younger (<50 year) have private insurance, reside in urban settings, or plan for subsequent reconstruction are more likely to undergo BM for unilateral BC. Genetic specific data were not evaluated for this patient cohort, and will be the subject of future analysis.
