Prognosis and clinical outcome of papilloma neoplasm of the breast: An observational study

Of 133 papillary lesions, 47 lesions were invasive solid papillary carcinoma, 7 lesions were invasive encapsulated papillary carcinoma, 31 lesions were solid papillary carcinoma, 27 lesions were encapsulated papillary carcinoma, 16 lesions were invasive papillary carcinoma, and 5 lesions were intraductal papillary carcinoma. The mean follow-up period was 64 months, during which we identified 6 cases of recurrence. Additionally, non-cancer-related deaths were observed in 2 patients. There was no significant difference in disease free survival (DFS) among all types, with a rate of 95.49 %. Similarly, overall survival (OS) showed no significant difference, with a rate of 98.5 % CONCLUSION: Papillary carcinoma is a rare variant of breast tumor. All papillary carcinomas, including the invasive types, exhibit an excellent prognosis. It is suggested that invasive papillary carcinoma should be considered a subtype with a favorable prognosis, allowing for minimization of treatment accordingly.
