Abstract: Objective To investigate the relationship between clinicopathologic features and prognosis of breast phyllodes tumor. Methods Fifty breast phyllodes tumor patients treated from January 2015 to January 2018 in our hospital were enrolled in the study and assessed for two-year recurrence rate and influencing factors of prognosis. Results Among the 50 cases, 13 cases （26.00%） recurred in two years; the recurrence was closely related to tumor size, age, tumor type, operation method, nuclear division, and mesenchyma （P<0.05）. Conclusion Benign breast phyllodes tumor has the clinicopathologic features of poor invasion, slow progression, and early onset. Its prognosis is closely related to nuclear division, mesenchyma, operation method, tumor type and diameter, age of disease onset, etc.
