摘要
Objective: In the absence of consistent guidelines for the use of adjuvant hormonal therapy (HT) in treating ductal carcinoma in situ (DCIS), our purpose was to explore a variety of factors associated with discussion, use, and discontinuation of this therapy for DCIS, including patient, tumor, and treatment-related characteristics and physician-patient communication factors.
Methods: We identified women from eight California Cancer Registry regions diagnosed with DCIS from 2002 through 2005, aged >= 18 years, of Latina or non-Latina white race/ethnicity. A total of 744 women were interviewed an average of 24 months postdiagnosis about whether they had (1) discussed with a physician, (2) used, and (3) discontinued adjuvant HT.
Results: Although 83% of women discussed adjuvant HT with a physician, 47% used adjuvant HT, and 23% of users reported discontinuation by a median of 11 months. In multivariable adjusted analyses, Latina Spanish speakers were less likely than white women to discuss therapy (odds ratio [OR] 0.36, 95% confidence interval [CI] 0.18-0.69) and more likely to discontinue therapy (OR 2.67, 95% CI 1.05-6.81). Seeing an oncologist for follow-up care was associated with discussion (OR 5.10, 95% CI 3.14-8.28) and use of therapy (OR 4.20, 95% CI 2.05-8.61). Similarly, physician recommendation that treatment was necessary vs. optional was positively associated with use (OR 11.2, 95% CI 6.50-19.4) and inversely associated with discontinuation (OR 0.38, 95% CI 0.19-0.73).
Conclusions: Physician recommendation is an important factor associated with use and discontinuation of adjuvant HT for DCIS. Differences in discussion and discontinuation of therapy according to patient characteristics, particularly ethnicity/language, suggest challenges to physician-patient communication about adjuvant HT across a language barrier.
