摘要：Background and Objective: The prevalence and incidence of breast cancer are much lower in Asian women than in Western women. However, data from various hospitals in Indonesia indicate that the incidence of breast cancer in the country has been rising by 2-8% over the last 10 years. Epidemiological studies have found that soy intake correlates to the low risk of breast cancer among Asian women. This study was conducted to prove the efficacy of tempeh consumption as a chemotherapy agent against breast cancer in DMBA-induced model animals. Materials and Methods: This study was a pre-clinical trial using a true experimental posttest-only control group design. The subjects were 25 white sprague-dawley rats that were induced with 7,12-Dimethylbenz[a]anthracene (DMBA). The observed parameters were AgNORs, BCl-2, Cas-3, p53 and VEGF. The test subjects were divided into a control group and 4 treatment groups that were given feed with modified tempeh starch contents of 1% (T1), 10% (T2), 50% (T3) and 75% (T4). Results: A tempeh diet had a significant effect on anti-proliferation and apoptosis markers in breast cancer cells (p<0.05). Conclusion: Of the four doses used in the trial, 50% tempeh flour was shown to be the most effective.
