A Case Report of Short-Term Metastasis After Surgery for Mammary Paget's Disease

Area of Science:

• Oncology
• Breast Cancer Research

Background:

• Mammary Paget's disease (MPD) often co-occurs with ductal carcinoma in situ (DCIS).
• Rapid metastasis is a significant concern in MPD with DCIS.
• HER2-positive status is linked to aggressive disease progression.

Purpose of the Study:

• To highlight the aggressive nature of HER2-positive MPD with DCIS.
• To emphasize the need for prompt diagnostic and surveillance strategies.
• To outline essential management principles for optimizing patient outcomes.

Main Methods:

• Review of clinical presentations and pathological findings in MPD with DCIS.
• Analysis of the impact of HER2 status on disease behavior.
• Discussion of treatment modalities and supportive care strategies.

Main Results:

• MPD with DCIS, particularly HER2-positive cases, demonstrates a propensity for rapid metastasis.
• Early systemic imaging and vigilant surveillance are critical postoperatively.
• Anti-HER2 therapies necessitate careful toxicity monitoring and management.

Conclusions:

• Aggressive management is required for HER2-positive MPD with DCIS.
• Personalized dose adjustments and multidisciplinary care are key to successful treatment.
• Proactive management of treatment-related toxicities improves patient outcomes.
