Abstract
Background and Objectives: Breast cancer is the most common malignant tumor in women worldwide and is divided into different subgroups based on histopathological and biological characteristics. This study aims to compare the biological status of breast tumors in patients with metastatic and non-metastatic breast cancer to assess the possibility of predicting metastatic and invasive types and to reduce the dangerous complications that may follow.
Subjects and Methods In this retrospective cross-sectional study, data from patients with breast cancer and metastatic breast cancer diagnosed within a two-year period from 2021 to 2023 were collected. The data included demographic information, types of biological receptors (ER, PR, Ki67, and Her-2), and survival status, all recorded in a questionnaire for analysis.
Results Her2-positive cases were 32.75 %( N=231) in the non-metastatic group and 34.38 %( N=68) in the metastatic group. Ki67 in the metastatic group was 33.8% low, 61.3% moderate, and 4.9% high, while in the second group it was 30.8% low and 69.2% moderate, with no high cases. ER-positive cases were 68.4% in the non-metastatic group and 70.8% in the metastatic group. PR-positive cases were 54.8% in the non-metastatic group and 56.9% in the metastatic group. Lymphadenopathy cases were 54.2% in the non-metastatic group and 69.0% in the metastatic group.
Conclusion no statistically significant differences between the clinical and biological characteristics of patients with and without metastasis. The distribution of various markers such as Her2, Ki67, ER, and PR was similar in both groups, and these markers cannot definitively predict the difference between patients with and without metastasis.
