Delaying surgery for a noninvasive breast cancer can have dire consequences.

👉A new study published by researchers from Fox Chase Cancer Center showed that delaying surgery for a noninvasive breast cancer can have dire consequences.

👉Longer delays in surgery for ductal carcinoma in situ (DCIS) breast cancer lead to a higher risk of invasive ductal carcinoma and a slightly lower survival rate says Dr. Arrangoiz based on the results of the study.

👉For each month of delay, there was well under a 1% difference in survival.

👉But for each month of delay, there was an approximate 1% increase in the finding of invasive cancer.

👉DCIS arises from abnormal cells form the milk duct of the breast and is the earliest stage of breast cancer.

👉When cancerous cells spread beyond the milk duct, it becomes invasive ductal carcinoma.

👉Standard treatment for DCIS is surgery and radiotherapy, along with endocrine therapy.

👉But research suggests that some DCIS may never progress to invasive disease, and clinical trials are being conducted to determine whether DCIS can be observed, rather than surgically removed.

👉This study suggests that delays in operative management of DCIS are associated with invasion and slightly worse short-term outcomes.

👉Since observation represents infinite delay, it suggests that observation should not yet be pursued outside of a clinical trial in patients who will tolerate excision.

👉The study included more than 140,600 U.S. women (123,947 with DCIS, 16,668 with invasive ductal carcinoma).

👉They were diagnosed between 2004 and 2014.

👉Survival was compared with five time intervals in delays to have surgery: less than 30 days, 31-60 days, 61-90 days, 91-120 days, or 121-365 days.

👉Overall survival was 95.8%, with a median time from diagnosis to surgery of 38 days.

👉However, each increase in diagnosis-to-surgery interval was associated with a 7.4% increase in the risk of death.

👉The study was published in the Annals of Surgical Oncology.
