The Reconstruction Choice for Giant Phyllodes Tumor of Breast: Bi-pedicled Deep Inferior Epigastric Perforator Flap

摘要

Abstract Background Phyllodes tumors of the breast are the rarest of all breast neoplasms. Giant phyllodes tumors (10?cm) of the breast have been less discussed in the literature. Reconstruction of the large defect created after wide excision (safety margin 1?cm) is a challenge in these patients. We present one technique using a bi-pedicled deep inferior epigastric perforator flap for post-mastectomy breast reconstruction for giant phyllodes tumors. Methods and Results We treated three patients with giant phyllodes tumors between 2013 and 2016. The histological characteristics were benign and borderline; tumor sizes were 18?×?13?×?12, 20?×?16?×?9.5, and 18?×?15?×?9?cm. Immediate post-mastectomy reconstruction was performed using bi-pedicled deep inferior epigastric perforator flaps. Flap sizes measured 30?×?11, 28?×?12, and 28?×?13?cm. Total operative time, including that for mastectomy, was 285, 425, and 410?min. The duration of hospital stay was 12, 13, and 9?days. No local recurrence or distant metastasis occurred in the first two patients over a follow-up period of 3?years and in the third patient over a follow-up period of 6?months. Conclusion A higher local recurrence rate was associated with positive margins, histological grade, tumor size, and necrosis. Immediate post-mastectomy breast reconstruction may become the preferred option for treatment of giant phyllodes tumors. A bi-pedicled deep inferior epigastric perforator flap conferred adequate leverage for wide excision and resolved scar contracture of the axilla. Good functional and cosmetic results were achieved.
