The effect of doxorubicin curcumin co-loaded lipid nanoparticles and doxorubicin on osteosarcoma before surgery.

Background: The research aims to observe the difference in the effect of preoperative doxorubicin curcumin co-loaded lipid nanoparticles (DOX+CUR LPNs) and doxorubicin (VAD) in the treatment of osteosarcoma. Methods: 68 patients with osteosarcoma who visited the hospital from January 2020 to December 2022 are chosen. They are separated into VAD group and DOX+CUR LPNs group, with 34 cases in each group. VAD and DOX+CUR LPNs groups VAD chemotherapy, and DOX+CUR LPNs treatment, respectively. All patients receive tumor resection. Comparison is made between the two groups before chemotherapy, at the end of chemotherapy and 1 week after surgery on the changes of vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2), galectin-3 (Gal-3), renal function indicators cystatin-C (Cys-C), serum creatinine (Scr), blood urea nitrogen (BUN) in the peripheral blood. The clinical efficacy and adverse reactions are determined by observation and follow-up for 1 month. Results: The VEGF, Ang-2, and Gal-3 in both groups were significantly lower at 1 week after chemotherapy and surgery compared to before chemotherapy (P < 0.05). The VEGF and Gal-3 in the DOX+CUR LPNs group were lower than those in the VAD group in the same period, with P < 0.05. The Cys-C, Scr, and BUN in both groups of patients after chemotherapy and surgery increased compared to before chemotherapy, with P < 0.05. The Cys-C, Scr, and BUN in the DOX+CUR LPNs group were lower than those in the VAD group during the same period, with P < 0.05. Following up for 1 month, the ORR of the DOX+CUR LPNs group was 94.12% (32/34) higher than that of the VAD group, with P < 0.05. The incidence of adverse reactions in the DOX+CUR LPNs group was 47.05% lower than that in the VAD group, with P < 0.05. Conclusion: Preoperative application of DOX+CUR LPNs enables effective drug delivery to the tumor section by combining the antibacterial, antioxidant and anti-inflammatory effects of curcumin, which is co-wrapped in nanoparticles. It has the effect of promoting angiogenesis and damage repair, inhibiting inflammation-related factors, and protecting renal function, while adriamycin alone has drug resistance problems and toxic side effects, which can damage the patient's liver and kidney. Therefore, DOX+CUR LPNs are more effective than adriamycin alone, indicating that it can improve the therapeutic effect of the drug and reduce the side effects, which is of great significance for improving the survival rate and quality of life of patients.
