Brief Summary:
This study looks at the risks and benefits of active surveillance (AS) compared to guideline concordant care (GCC) in the setting of a pragmatic prospective randomized trial for low risk DCIS. Our overarching hypothesis is that management of low-risk Ductal Carcinoma in Situ (DCIS) using an AS approach does not yield inferior cancer or quality of life outcomes compared to GCC.

Detailed Description:

Overdiagnosis and overtreatment resulting from mammographic screening have been estimated to be as high as 1 in 4 patients diagnosed with breast cancer although the absence of standard definitions for measuring overdiagnosis has led to much uncertainty around this estimate. The national health care expenditure resulting from false positive mammograms and breast cancer overdiagnosis has been estimated to approach $4 billion annually. There is general consensus that much of this burden derives from the treatment of DCIS; for those estimated 40,000 women per year whose DCIS may never have progressed even without treatment, medical intervention can only harm. In those women who undergo surgical management of DCIS, there is risk of developing persistent pain at the surgical site, with estimates ranging from 25-68%. Importantly, persistent pain after lumpectomy may be as prevalent as that after total mastectomy. Persistent postsurgical pain is rated by patients as the most troubling symptom, leading to disability and psychological distress, and is often resistant to management. Although prospective population-based data have demonstrated significant patient and surgical focus on pain with remarkably high levels of chronic pain 4 and 9 months after breast surgery, much of these data have been collected in women with invasive cancer, with little data directly relevant to patients with DCIS.

The overarching hypothesis of the study is that management of low-risk DCIS using an active surveillance (AS) approach does not yield inferior cancer or quality of life outcomes compared to guideline concordant care (GCC).

  9. Breast specific pain [ Time Frame: Baseline, 6 months, 1 year, and once a year (years 2 through 5) ]
    Breast specific pain will be measured by the Breast Cancer Pain Questionnaire (BCPQ); the BCPQ includes assessment of pain severity, pain frequency (how many days/week), and pain location (breast, arm, side, axilla), from which a Pain Burden Index (PBI) can be calculated

    The Decision Regret Scale will measure how women perceived their DCIS treatment decision. The SURE scale, which is composed of four items from the Decisional Conflict Scale will be used to measure patients' uncertainty about which treatment to choose and factors contributing to uncertainty (feeling uninformed, unclear values, and unsupported in decision-making).

  12. Knowledge [ Time Frame: Baseline and 2 years ]
    DCIS and breast cancer knowledge will be measured with items adapted from the Breast Cancer Surgery Decision Quality Instrument (BCS-DQI) as well as questions developed specifically for a study that assessed DCIS knowledge and risk perceptions. The investigators will assess risk perceptions in women with DCIS using questions developed by Lerman and Croyle that will measure risk perceptions in relation to psychosocial outcomes in women with DCIS

    Measured by the Breast Cancer Surgery Decision Quality Instrument (BCS-DQI)

  14. Communication with physicians [ Time Frame: Baseline ]
    To assess communication with physicians about DCIS management options, the investigators will adapt items used in a prior study of surgical decision-making, including the extent to which their physician talked to them about AS vs. GCC. Additionally the investigators will ask about sources of information for the management of their DCIS

  15. Financial burden [ Time Frame: 6 months ]
    The investigators will adapt items from the National Health Interview Survey and the Cancer Outcomes Research and Surveillance (CanCORS) Study to assess financial burden. The investigators will also ask women to Cancer Care estimate out of pocket expenses attributed to their DCIS diagnosis.

  16. Employment status [ Time Frame: Baseline, 6 months, year 1, and once a year (years 1 through 5) ]
    Employment status will be assessed using a measure that is being added to the Alliance Patient Questionnaire as it has been tested and validated in breast cancer populations.

  17. Concerns about future breast events [ Time Frame: Baseline and 2 years ]
    Four items from the Quality of Life in Adult Cancer Survivors (QLACS) scale will be adapted to evaluate frequency (1=never; 7=always) of worries about DCIS, including concerns about future breast events and death from DCIS
