|May 1, 1978
Summary
Tumor size, stromal atypia, and mitotic activity help predict cystosarcoma phyllodes behavior. These factors aid in classifying tumors as benign, borderline, or malignant, guiding treatment and prognosis.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Cystosarcoma phyllodes (CSP) are rare breast tumors with unpredictable clinical behavior.
- Accurate prognostic indicators are crucial for effective management of CSP.
Purpose of the Study:
- To evaluate clinicopathologic features of CSP.
- To determine if tumor size, contour, stromal atypia, and mitotic activity predict clinical behavior.
Main Methods:
- Retrospective clinicopathologic evaluation of 42 CSP cases.
- Analysis of tumor size, contour, stromal atypia, and mitotic activity.
- Correlation of these features with patient prognosis and clinical outcomes.
Main Results:
- Stromal atypia and mitotic activity correlated with prognosis, unlike tumor size.
- A classification system identified 18 benign, 5 borderline, and 19 malignant CSP.
- Local recurrences occurred across all categories; systemic metastases were seen only in malignant CSP.
- One borderline tumor recurred, leading to fatal pulmonary involvement.
Conclusions:
- Stromal atypia and mitotic activity are reliable indicators of CSP prognosis.
- Classification based on these features aids in predicting tumor behavior.
- Further research is needed to clarify the origin of malignant CSP stroma for improved prognosis.
