Breast Cancer Integrative Oncology: Prospective Matched Controlled Outcomes Study

Aim 2: Compare health-related quality of life (HRQOL) experienced by a group of breast cancer patients receiving IO care with HRQOL of a group of matched comparison women.

Time Frame: 6-60 months post-enrollment

Comparison will be between breast cancer patients living in the same geographic area with similar prognostic characteristics (age, stage of cancer at diagnosis, estrogen receptor/ progesterone receptor (ER/PR) status, race, ethnicity, and marital status) at the time of their initial diagnosis with breast cancer who did not receive IO care. We will identify an average of three (up to four each) matched controls for each eligible IO clinic cancer patient from the Western Washington CSS database and to invite them to enroll in the outcomes study.

Aim 1: Describe treatments received by breast cancer patients receiving physician level practitioner IO care and the cost of IO care.

Time Frame: Baseline, 6, 12, 24, 36, 48, and 60 months post study enrollment.

Will also describe how long after diagnosis women with breast cancer seek IO care and differences in IO care prescriptions associated with when, in a woman's course of treatment, she seeks care. This patient cohort will consist of all female patients with breast cancer seeking IO clinic care. Our analyses will describe how long after diagnosis women with breast cancer seek IO care and describe differences in IO care prescriptions associated with when, in a woman's course of treatment, she seeks care.
