Sternal Resection and Reconstruction for Malignant Phylloides Tumor.

Area of Science:

• Oncology
• Surgical Oncology
• Biomaterials Science

Background:

• Malignant phylloides tumors (MPTs) are rare breast neoplasms, accounting for <1% of all breast cancers.
• MPTs are locally aggressive with a significant risk of recurrence.
• Multidisciplinary management is crucial for MPTs.

Purpose of the Study:

• To report a unique case of malignant phylloides tumor involving the sternum.
• To describe the surgical technique and outcome of total sternal resection and reconstruction.
• To highlight the use of Biopore High-Density Polyethylene (HDPE) prosthesis in complex chest wall reconstruction.

Main Methods:

• A case of MPT with sternal involvement was identified.
• Surgical management involved en bloc resection of the sternum.
• Reconstruction was performed using a custom-designed Biopore HDPE prosthesis.

Main Results:

• Complete resection of the malignant phylloides tumor was achieved.
• The Biopore HDPE prosthesis provided stable chest wall reconstruction.
• The patient experienced a favorable postoperative recovery without immediate complications.

Conclusions:

• Malignant phylloides tumors can present with extensive local invasion, including sternal involvement.
• Total sternal resection is a viable option for managing such advanced cases.
• Biopore HDPE prosthesis offers a suitable solution for complex sternal reconstruction, facilitating oncologic resection and functional restoration.
