AI in DCIS: Bridging Predictive Gaps
Ductal Carcinoma In Situ (DCIS) is a complex, heterogeneous precursor to breast cancer, with widely variable invasive potential. Current methods for predicting this invasion risk often lack the personalization needed for optimal patient care. This study explores the potential of artificial intelligence (AI) to enhance mammography analysis, specifically for predicting invasion risk in DCIS patients. A key finding is the high Negative Predictive Value (NPV) of 96.2%, suggesting that AI-assisted analysis can effectively rule out invasion in a significant proportion of DCIS cases. This capability is crucial for identifying candidates for less aggressive surgical treatments and advancing personalized DCIS management strategies.
Rigorous AI Evaluation Framework
This retrospective cohort study included 74 patients with pathologically confirmed DCIS by preoperative biopsy. All radiological examinations were standardized at a single dedicated breast imaging center. The core of the analysis involved a deep learning-based AI system, Transpara version 1.7.4, which classified patients into low-risk and high-risk groups for invasion. These AI classifications were rigorously validated against postoperative histopathological findings, which included details on invasion presence and type. Statistical analyses focused on calculating sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy to robustly assess the AI system's performance.
Unveiling AI's Predictive Power
Invasion was detected in 19 out of 74 (25.7%) patients. Remarkably, the AI system classified 18 of these 19 invasive cases (94.7%) into the high-risk group. The model demonstrated a 94.7% sensitivity, 45.5% specificity, 37.5% PPV, and an impressive 96.2% NPV, with an overall accuracy of 58.1%. Subgroup analyses further revealed that for patients aged ≥ 50 years and those with lesions ≥ 3 cm, the NPV reached 100%, indicating enhanced reliability in these groups. A significant relationship was also observed between the presence of necrosis and invasion (p=0.004), confirming AI's ability to capture critical histopathological markers.
Shaping Future DCIS Management
The high NPV of 96.2% is a pivotal finding, positioning AI-assisted mammography as an effective rule-out tool for invasion in DCIS. This can confidently identify patients who may safely pursue less aggressive treatments or active surveillance, thereby reducing unnecessary interventions and associated morbidity. While the model exhibited high sensitivity, its moderate specificity and PPV suggest that AI should serve as a complementary tool, not a sole diagnostic determinant, to avoid overdiagnosis. The statistically significant correlation between necrosis and invasion, effectively identified by the AI, highlights its potential to integrate imaging and pathological insights. Future efforts will focus on validating these findings in larger, multi-center studies, aligning with ongoing trials like COMET, LORD, and LORIS, to fully integrate AI into personalized DCIS management.

Negative Predictive Value for Invasion
The AI system's exceptional NPV allows clinicians to confidently rule out invasion in DCIS patients, making it a powerful tool for de-escalating treatment and preventing unnecessary procedures.

The AI system demonstrates significantly higher sensitivity in detecting microinvasion compared to traditional clinical suspicion, highlighting its value as an advanced complementary diagnostic tool.
Understanding a False Negative: A Critical Case Study
A 46-year-old premenopausal woman presented with 1.5 cm high-grade DCIS, microcalcifications, and a BI-RADS 4 classification. Pathological features included mixed architectural patterns (solid, cribriform, comedo) and necrosis. Despite these high-risk indicators, there was no clinical suspicion of microinvasion on biopsy, and the AI system assigned a score below the 70% threshold, classifying it as low-risk. Postoperative pathology, however, revealed pT1a invasive carcinoma (Luminal B HER2-positive subtype). This case underscores the importance of ongoing validation and the complementary role of AI in complex scenarios.
Outcome: AI classified as low-risk, but final pathology revealed pT1a invasive carcinoma.
Learnings: AI should be viewed as a complementary tool, not a sole decision-maker. Continuous validation and integrated assessment are crucial, especially in complex cases where pathological features suggest higher risk despite AI's initial classification.
AI Correlates Imaging Features with Pathological Markers
A statistically significant relationship was observed between the presence of necrosis and invasion (p=0.004). This finding suggests that the AI algorithm effectively captures histopathological risk factors directly from imaging data, corroborating existing literature that emphasizes necrosis as a crucial prognostic marker in DCIS. This integration of imaging and pathological insights enhances the potential for personalized risk assessment.
