Abstract

The phyllodes tumor is characterized by its tendency to recur locally and occasionally to metastasize. The purpose of the present paper was to assess the prognostic value of clinical-morphological characteristics in patients with phyllodes tumor. Forty-seven cases of phyllodes tumors was studied; the World Health Organization classification was used and follow up was obtained. A total of 51%, 28% and 21% of the tumors were classified as benign, borderline and malignant, respectively. The adherence (P = 0.01), size >10 cm (P = 0.001), high mitotic activity (P = 0.03), infiltrative tumor margin (P = 0.0002) and type of surgery in malignant tumors (P = 0.02) proved to be good predictors of relapse. The presence of pain (P = 0.03), postmenopausal status (P < 0.04), heavy cellular pleomorphism (P = 0.007), high mitotic activity (P = 0.002), tumoral grade (P = 0.006) and metastasis (P < 0.00001) were prognostic factors of poor survival. Tumoral grade and some clinical-morphological characteristics of patients with phyllodes tumors have a significant impact on the prediction of its biological behavior.
