[Surgery for phyllodes tumors of the breast: Is the denomination of a giant phyllodes tumor justified?]

Introduction: In Africa, rare publications have focused on phyllodes tumors (PTs). The aim of our study is to describe the special feature of PTs surgery.

Patients and method: Retrospective and descriptive study of 11 cases of PT operated from January 1, 2015 to March 31, 2023 at the medical-surgical clinic in Teaching Hospital Center of Sylvanus Olympio of Lome. The patients had a breast ultrasonography with or without mammography and core needle biopsy. Epidemiological, clinical and therapeutic data were record. The follow up was regularly at 1 month, 3 months and every 6 months.

Results: The PT was 4.9% of breast tumors operated on. The mean age was 29years (range 18 to 61). The 20-30 age group was the most represented in 5 cases. Self-examination of a breast nodule, breast pain, and fear of cancer were noted in 11, 4, and 2 cases, respectively. The mean time to admission was 8 months (range 6 to 18). The mean tumor size was 6.4cm (range 3-11). Breast-conserving surgery was performed in 10 patients and mastectomy in 1 case with R1 resection. We noted necrosis of the areola and nipple plate. The histopathology types are classified into benign (3), intermediate (6) and malignant (2). R1 resection noted local recurrence, then metastatic recurrence and death at 16months.

Conclusion: TPs were described as giant (size greater than 5cm). There is no preset technique to apply. Conservative surgery is our preference while respecting a Ro margin, a breast remaining aesthetic and a lower scar price.
