This study examined the time from breast cancer diagnosis to initiation of treatment among Alaska Native (AN) women. We evaluated the impact of age, cancer stage, and rural/urban residence at diagnosis.
We evaluated characteristics of women recorded in the Alaska Native Tumor Registry who received a first diagnosis of breast cancer between 2009 and 2013. Median time from diagnosis to treatment was assessed. Associations of demographic and clinical characteristics with timely initiation of treatment were evaluated using logistic regression and Cox proportional hazards models.
Two hundred seventy-eight (278) AN women were diagnosed with invasive breast cancer in years 2009-2013. Mean age at diagnosis was 56.8 years (SD = 13.0). The median time from diagnosis to initiation of treatment was 23 days (P < .05) with most (94.6%, n = 263) meeting the ≤60-day guideline target. Time to treatment was not associated with rural/urban residence, age, or stage at cancer diagnosis.
These findings indicate that most AN women diagnosed with breast cancer within the AN Tribal Health System receive timely treatment after diagnosis.
本研究调查了阿拉斯加原住民（AN）女性从乳腺癌诊断到开始治疗的时间。我们评估了年龄、癌症分期和诊断时的城乡居住情况的影响。
我们评估了 2009 年至 2013 年间在阿拉斯加原住民肿瘤登记处接受首次乳腺癌诊断的女性的特征。评估了从诊断到治疗的中位时间。使用逻辑回归和 Cox 比例风险模型评估人口统计学和临床特征与及时开始治疗的相关性。
278 名（278 名）AN 女性在 2009-2013 年期间被诊断患有浸润性乳腺癌。诊断时的平均年龄为 56.8 岁（SD=13.0）。从诊断到开始治疗的中位时间为 23 天（P<0.05），大多数（94.6%，n=263）符合≤60 天的指南目标。治疗时间与城乡居住、年龄或癌症诊断时的分期无关。
这些发现表明，在 AN 部落卫生系统内诊断出患有乳腺癌的大多数 AN 女性在诊断后会及时接受治疗。
