Despite an aging population, there are no established treatment guidelines for women with ductal carcinoma in situ (DCIS) age ≥80. Here we describe national treatment patterns and survival outcomes in older women with DCIS.Women age ≥80 diagnosed with DCIS from 2005 to 2014 were identified using the National Cancer Database. χ2, Fisher's exact test, and logistic regression models were used to identify factors influencing receipt of breast surgery, and Kaplan-Meier method and Cox proportional hazard models were used to evaluate overall survival (OS).A total of 6,070 women with DCIS met inclusion criteria, of which the majority (98%) received surgery. Receipt of surgery was independently associated with age90. OS was higher for those who received surgery compared to those who did not (HR 2.2 [1.72-2.83] P.001).The vast majority of patients age ≥80 with DCIS in the National Cancer Database received primary surgical management, which was associated with a significant OS benefit. Considering comorbidities and patient fitness, surgical resection should be considered for all patients age ≥80 who are suitable operative candidates. |
