Abstract

PURPOSE
To identify predictive factors of upstaging from diagnosed ductal carcinoma in situ (DCIS) to invasive cancer after surgical excision.
METHODS
One hundred seventy-four patients diagnosed with DCIS based on biopsies between January 2009 and December 2014 were evaluated. Patients' clinicopathological variables were assessed to identify predictive factors of invasive carcinoma from final pathology.
RESULTS
One hundred seventy-four cases of DCIS were included. Of these, 42 were upstaged to invasive carcinoma on the final excision. Preoperative features such as age 40 years or younger at diagnosis, presence of a palpable mass, ultrasonography (USG)-guided core needle biopsy, tumor size ≥20 mm on USG, high grade DCIS, cribriform DCIS, comedo necrosis, presence of intraluminal calcification, estrogen receptor negativity, progesterone receptor negativity and triple-negative subtype were significantly associated with the risk of invasive carcinoma. Multivariate analysis showed that a tumor size ≥20 mm on USG and triple negative subtype were independently associated with upstaging.
CONCLUSION
Tumor size ≥20 mm on USG and triple-negative subtype were independently associated with the upstaging of DCIS to invasive cancer.
