Abstract:
Background and purpose: Paget's disease (PD) of the breast is a rare disease. The survival of PD was reported to be related to the characteristics of the underlying carcinoma. This study aimed to investigate the char-acteristics and survival of PD patients with underlying invasive breast carcinoma (IBC). Methods: Fifty-four patients diagnosed with PD and an associated IBC in Fudan University Shanghai Cancer Center from 2002 to 2007 were re-cruited in this study as study group. Since most PD overexpress HER-2, 72 patients with HER-2-overexpressing breast cancer were randomly recruited as control group. This study compared survival between these two groups. Results:Twenty-five (46.3％) patients in study group had no clinical manifestation of PD and were diagnosed unexpectedly by a histologic examination. Thirty-five (64.8％) patients in study group had tumors larger than 2 cm, twenty-six(48.1％) patients in study group had chance of axillary lymph node involvement. Compared with control group, patients in study group tended to have more events (5-year relapse-free survival: 76.4％ vs 48.5％, P<0.01). In the control group, most events occurred in the first 3 years after operation, while recurrence might happen all along in the 5 years after opera-tion in study group. Patients in study group also had a poorer overall survival than in control group (61.0％ vs 80.6％, P=0.01). Conclusion: Patients with Paget's disease and underlying invasive breast cancer tend to have poorer survival than those with HER-2-overexpressing breast cancer.
