Clinical Analysis of Trastuzumab-Targeted and Chemotherapy Treatment for Breast Cancer Patients

Objective: To explore the clinical effectiveness and safety of trastuzumab combined with chemotherapy in breast cancer patients. Methods: Eighty patients with postoperative local recurrence of breast cancer were divided into a control group (chemotherapy only) and an observation group (chemotherapy plus trastuzumab-targeted therapy). The clinical efficacy, adverse reactions, and complications were compared between groups. Results: The overall effective rate of clinical treatment in the observation group was higher than that in the control group (P < 0.05). The incidence of adverse reactions showed no difference between the groups (P > 0.05), while the complication rate was significantly lower in the observation group (P < 0.05). Conclusion: Trastuzumab-targeted therapy combined with chemotherapy can significantly improve clinical treatment outcomes for breast cancer patients, reduce the risk of complications, and maintain good safety, making it suitable for clinical promotion.
