Hypothesis

The study aims to assess the prognostic significance of various biomarkers, including bcl-2, in breast cancer patients treated with specific chemotherapy.

Conclusion

Bcl-2 is an independent prognostic factor of disease-free survival in stage III breast cancer patients.

Supporting Evidence

  • Bcl-2 expression was significantly correlated with longer disease-free survival.
  • Negative bcl-2 expression was identified as an independent indicator of poorer disease-free survival.
  • Patients with bcl-2 expression had a significantly longer disease-free survival than those without.

Takeaway

This study found that a protein called bcl-2 can help predict how well breast cancer patients will do after treatment.

Methodology

The study analyzed clinico-pathologic characteristics and biomarker expressions in 151 stage III breast cancer patients who received specific chemotherapy.

Limitations

The study was conducted at a single institution and included only patients treated with a specific chemotherapy regimen.

Participant Demographics

151 patients (3 male, 148 female) with a median age of 46 years.

Statistical Information
