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.
