Hypothesis
The DDR2/collagen type I axis contributes to breast cancer progression and chemoresistance.
Conclusion
DDR2 is a poor prognostic factor in breast cancer, associated with increased cell proliferation and chemotherapy resistance.
Supporting Evidence
- DDR2 expression was positively correlated with aggressive behaviors of breast cancer.
- Patients with DDR2-positive tumors had a higher risk of recurrence, especially after chemotherapy.
- In vitro studies showed that DDR2 promotes breast cancer cell proliferation and chemoresistance.
Takeaway
This study found that a protein called DDR2 helps breast cancer grow and resist treatment, especially when it interacts with a type of collagen.
Methodology
The study involved immunolocalization of DDR2 and collagen type I in breast cancer tissues and in vitro experiments with breast cancer cell lines.
Participant Demographics
Japanese female patients aged 27–88 years.
Statistical Information
P-Value
p = 0.0013 for disease-free survival, p = 0.034 for breast cancer-specific survival.
Statistical Significance
p<0.05
