Ductal carcinoma in situ (DCIS) detection has increased with mammography. Nuclear grade is the best predictor of recurrence, though histological assessment alone is insufficient for managing DCIS patients.

Area of Science:

  • Oncology
  • Pathology
  • Radiology

Background:

  • Mammographic screening has increased ductal carcinoma in situ (DCIS) detection.
  • Mastectomy is increasingly replaced by local excision for DCIS treatment.
  • Assessing complete excision of DCIS is challenging due to technical difficulties.

Purpose of the Study:

  • To review the histological features of DCIS and their correlation with clinical outcomes.
  • To evaluate the effectiveness of different DCIS classification systems.
  • To determine the best predictors of recurrence in DCIS.

Main Methods:

  • Review of current literature on DCIS detection, treatment, and histological assessment.
  • Analysis of the prognostic value of various histological features, including nuclear grade and necrosis.

  • Comparison of different DCIS classification systems based on reproducibility and predictive power.

    • Main Results:

    • Nuclear grade is the strongest predictor of DCIS recurrence and its timing.
    • Necrosis is a useful feature when combined with nuclear grade.
    • Comedo pattern and other histological features have limited clinical value and consistency.

    Conclusions:

    • Histological assessment alone is insufficient for DCIS management.
    • Excision margin status, lesion size, and radiological/clinical features are crucial for patient management.
    • Further research is needed to improve the consistency and predictive power of histological assessment in DCIS.
