This study aims to explore the effectiveness of combining 99mTc-MIBI scintigraphy with color Doppler ultrasound diagnosis and clinical palpation for evaluating the efficacy of neoadjuvant chemotherapy (NAC) in treating breast cancer. The study included 70 cases of non-operated breast cancer patients with a total of 76 lesions. Clinical palpation, color Doppler ultrasound, and 99mTc-MIBI scintigraphy were conducted before NAC chemotherapy and after 2~3 courses of chemotherapy. In the assessment, a tumor response (STR) of >30% based on 99mTc-MIBI imaging was considered effective, and the clinical efficacy was evaluated according to the WHO criteria. The post-NAC surgical pathological response was used as the standard, with Grade I defined as ineffective and Grades II and III as effective. The study assessed the radiotracer uptake ratio (T/N) in breast cancer patients before and after neoadjuvant chemotherapy (NAC) using 99mTc-MIBI scintigraphy. The result indicated that the effective cases of NAC chemotherapy were 45 (n = 45), and the T/N values before and after treatment were 3.326 ± 1.119 and 1.996 ± 0.792, respectively, with a statistically significant difference observed (t = 19.986, p < 0.001). The result demonstrated that NAC chemotherapy was ineffective (n = 31), the T/N values before and after treatment were 3.001 ± 1.153 and 2.434 ± 1.104, respectively, showing a statistically significant difference (t = 8.181, p < 0.001).
