A Multidisciplinary Perspective on Breast Phyllodes Tumors: A Literature Review

Area of Science:

• Oncology
• Pathology

Background:

• Phyllodes tumors, also known as cystosarcoma phyllodes, are rare fibroepithelial neoplasms of the breast.
• They are characterized by leaf-like histological structures and classified by the WHO into benign, borderline, and malignant categories.
• These tumors represent 0.3% to 1% of all breast tumors, with peak incidence in women aged 40-52.

Purpose of the Study:

• To review the classification, diagnosis, and treatment of breast phyllodes tumors.
• To highlight the importance of histopathological and imaging modalities in managing these rare neoplasms.

Main Methods:

• Review of current literature on phyllodes tumors.
• Analysis of diagnostic criteria including imaging (mammography, ultrasound, MRI) and histopathology (cellularity, mitotic activity).
• Discussion of immunohistochemical markers (Ki-67, p53) and treatment strategies.

Main Results:

• Phyllodes tumors exhibit diverse histopathological features influencing their categorization.
• Imaging and histopathology are crucial for diagnosis, categorization, and prognosis.
• Complete surgical excision with adequate margins is the primary treatment; adjuvant therapies like radiotherapy are debated.

Conclusions:

• Accurate diagnosis and categorization of phyllodes tumors are essential for effective management.
• Multidisciplinary approaches integrating imaging, histopathology, and clinical expertise are vital.
• Further research into adjuvant therapies may refine treatment protocols for malignant phyllodes tumors.
