Abstract
Aim: We aimed to study the characteristics of the breast cancer patients with positive HER2/neu+, ER- and PR- receptors. Methods: 119 patients with breast cancer were included in this retrospective cohort study from 2006 to 2016. The overall and disease-free survival were evaluated. Results: Most prevalent type of tumor was IDC, grade III cancer and stage II. Recurrence/metastasis occurred in 18.49%. Most common sites of metastasis were lungs and liver. Total mortality rate was 10.92%. Overall and disease-free survival times were 40.04 and 22.29 months, respectively. The median survival time was about 118 months. Conclusion: Breast cancers with positive HER2/neu and negative estrogen and progesterone receptors had low overall and disease-free survival rates compared with ER+/PR+/HER2- tumors.
