Abstract
ObjectiveTo study the clinical pathological features between the subtypes of the female mucinous breast cancer with its prognosis.
MethodsEighteen cases confirmed as pure mucinous breast cancer (PMBC) with complete case report and follow-up information in Beijing Shijitan Hospital was collected and divided into type A PMBC and type B PMBC. A retrospective analysis was performed for both groups on clinical and pathological features and prognosis.
ResultsThe axillary metastasis rate for type A PMBC was 13.3%, and 0 for type B PMBC. The distant metastasis rate for type A was 6.7%, and 0 for type B. The percentage of ER and PR positive cases for type A was 93.3% and 86.7%, respectively, and was both 33.3% for type B. The HER-2 gene overexpression rate was both 0 for type A and B. And for Ki-67 expression, the low and high expression rate for type A was 80.0% and 20.0%, respectively, and was 100.0% and 0 for type B, respectively.
ConclusionsPMBC is a special subtype of the breast cancer with good prognosis. The pathological features and biological behavior between type A and type B is different. Further research and more data will be needed to access the prognosis with the classification.
