[Usefulness of endoscopic resection for phyllodes tumor of the breast].

We compared the surgical margins for phyllodes tumors of the breast required for endoscopic local excision and normal local excision. Over a 10-year period, we experienced 38 patients with phyllodes tumors of the breast who were treated by surgical operation. Thirty-three patients underwent local excision with a surgical margin of at least 1.0 cm, and 5 underwent endoscopic local excision with a surgical margin of at least 1.0 cm. The pathological surgical margins were negative in all patients. The surgical margins for both endoscopic local excision and normal local excision were almost identical. However, the surgical wounds caused by endoscopic local excision were smaller than those caused by normal local excision. These results suggest that endoscopic local excision is a useful method for phyllodes tumor.
