Bridging the Gap: Improving Accuracy in Preoperative Breast Cancer Staging

Accurate preoperative staging is crucial for effective breast cancer treatment planning. Yet, a recent study presented at the NCCN 2026 Annual Conference highlights a significant disconnect between radiological and pathological assessments of breast cancer stage, particularly in Pakistan. This discrepancy underscores the need for refined imaging protocols and a greater emphasis on intraoperative gross examination to optimize patient care.

The Challenge of Discordance

Researchers, led by Berkha Rani, MD, found that in a study of 160 patients undergoing modified radical mastectomy and axillary node dissection, radiological imaging overestimated the cancer stage in nearly half the cases (46.6%) and underestimated it in over 16%. While a statistically significant correlation existed between radiological and pathological staging (r=0.383, P=0.001), the weak correlation points to substantial inconsistencies. This means that treatment decisions based solely on imaging may not always reflect the true extent of the disease.

Imaging Modality Specifics

The study revealed specific trends among different imaging techniques. Mammography and MRI tended to overestimate tumor size, potentially leading to more aggressive surgical approaches than necessary. Conversely, ultrasound often underestimated tumor size, which could result in insufficient surgical margins and a higher risk of recurrence. Pathological examination, surprisingly, also tended to overestimate tumor size.

Why Accurate Staging Matters

Underestimating tumor size can lead to positive surgical margins, requiring further intervention. Overestimation, might preclude patients from breast-conserving therapy options, leading to unnecessary mastectomies. A multimodal approach – combining MRI, ultrasound, and mammography – is considered essential, but this study demonstrates that even with multiple modalities, discrepancies remain.

The Pakistani Context and Global Implications

While the study was conducted in a tertiary care hospital in Pakistan, the issue of staging discordance is not unique to the region. Delayed diagnosis, limited access to advanced imaging, and variations in interpretation can contribute to inaccuracies globally. Pakistan faces additional challenges, including cultural barriers to screening and limited treatment options, as highlighted in a recent review published in Discover Medicine. Improving early detection and access to accurate staging are critical priorities.

The Role of Gross Examination

Dr. Rani emphasized the importance of macroscopic and intraoperative gross examination as key methods for estimating tumor size, focality, and margin status. This reinforces the need for experienced surgeons and pathologists to carefully assess the tumor during surgery, providing real-time information to guide surgical decision-making.

Future Trends in Breast Cancer Staging

Several emerging trends promise to improve the accuracy of breast cancer staging:

• Molecular Profiling: Advances in genetic and molecular profiling, as discussed in the Journal of College of Physicians and Surgeons Pakistan, are shifting oncology towards personalized care. Analyzing tumor biomarkers can provide a more precise understanding of disease characteristics and predict treatment response.
• Artificial Intelligence (AI): AI-powered image analysis tools are being developed to assist radiologists in interpreting mammograms, MRIs, and ultrasounds, potentially reducing inter-observer variability and improving accuracy.
• Enhanced Imaging Techniques: Research into new imaging modalities, such as diffusion-weighted MRI and positron emission tomography (PET) scans, may offer improved sensitivity and specificity for detecting and staging breast cancer.
• Standardized Protocols: Implementing standardized imaging and pathological reporting protocols can minimize inconsistencies and ensure consistent staging across different institutions.
