Breast Cancer Nomogram: Ductal Carcinoma In Situ (DCIS) Recurrence

In consultation with a physician, this tool can be used by patients who have had breast-conserving surgery to treat ductal carcinoma in situ (DCIS) to predict the likelihood that their breast cancer will return in the same breast that was originally treated. Patients can use this information to make decisions regarding various treatment options, such as radiation therapy and anti-estrogen therapy.

CalculateClearEnter Your Information

Enter age at the time of diagnosis.
 years old (25 to 90)
Select YES if there are first- (e.g., mother or sister) or second-degree (e.g., paternal aunt or grandmother) relatives with breast cancer.
Select Clinical if there was an abnormality on physical examination; select Radiologic if an abnormality was seen only on breast imaging studies (e.g., mammography).
Select YES if radiation therapy is given after breast-conserving surgery.
Select YES if anti-estrogen treatment (e.g., tamoxifen, raloxifene).
Select the nuclear grade from the pathology report. (Low = slight or no variation in the size and shape of the cell nuclei; Intermediate/High = moderate to marked variation in the size and shape of the cell nuclei.)
Select YES if the pathology report states that there was necrosis associated with the DCIS.
Select “Negative” if there is a margin width of at least 2 mm. Select “Positive or Close” if margin width is 2 mm or less.
Indicate the number of surgical excisions that were required.
