We studied the process of care received by 1,680 female breast cancer patients treated in 17 community hospitals. The probability of receiving various diagnostic, consultation, therapy, or rehabilitation services was almost always significantly associated with patient age for one or more disease stages. Most often there was a linear trend for older patients to receive fewer services (e.g., biopsies prior to definitive treatment, number of lymph nodes examined, chemotherapy, radiation therapy) but other age patterns also were found. Age was not significantly associated with clinical staging or estrogen receptors.
我们研究了17家社区医院收治的1680例女性乳腺癌患者所接受的治疗过程。在一个或多个疾病阶段，接受各种诊断、会诊、治疗或康复服务的概率几乎总是与患者年龄显著相关。大多数情况下，老年患者接受的服务较少（如确定性治疗前的活检、检查的淋巴结数量、化疗、放疗）呈现线性趋势，但也发现了其他年龄模式。年龄与临床分期或雌激素受体无显著关联。
