DCIS and Active Monitoring: When Immediate Surgery May Not Be the Only Conversation
The management of ductal carcinoma in situ (DCIS) is entering a period of increasing treatment de-escalation
Clinical Scorecard: DCIS and Active Monitoring: When Immediate Surgery May Not Be the Only Conversation
At a Glance
Category Detail
Condition Ductal Carcinoma In Situ (DCIS)
Key Mechanisms Biological heterogeneity of DCIS and risk stratification based on pathologic and clinical factors.
Target Population Women age 40 and older with hormone receptor-positive, grade 1 or 2 DCIS without invasive disease.
Care Setting Oncology and breast surgery clinics.
Key Highlights
Active monitoring may be a viable alternative to immediate surgery for selected low-risk DCIS patients. The COMET trial showed noninferiority of active monitoring compared to guideline-concordant care. Risk stratification is essential for determining eligibility for active monitoring. Structured surveillance with predefined escalation pathways is required for active monitoring. Surgery remains integral to DCIS management but may be individualized for low-risk patients.
Guideline-Based Recommendations
Diagnosis
Use imaging to identify suitable candidates for active monitoring. Assess pathologic factors such as nuclear grade and hormone status.
Management
Consider active monitoring for low-risk DCIS patients. Discuss the potential for individualized timing of surgery.
Monitoring & Follow-up
Conduct diagnostic mammography every six months for the affected breast. Monitor for new clinical or imaging abnormalities that may require intervention.
Risks
Mammographic stability does not guarantee biological certainty regarding disease progression.
Patient & Prescribing Data
Women with low-risk DCIS diagnosed through screening mammography.
Active monitoring may reduce overtreatment in low-risk cases.
Clinical Best Practices
Engage in shared decision-making with patients regarding treatment options. Provide clear explanations about the nature of DCIS and the rationale for monitoring.
