Investigating the Relationship between of Vascular Endothelial Growth Factor and HER-2neu in IHC Staining with Metastasis and Mortality in Patients with Osteosarcoma
چکیده انگلیسی:
Background: The expression of HER-2neu and vascular endothelial growth factor (VEGF) in patients with osteosarcoma may determine the response to treatment. These two factors are likely to be effective in cancer progression. This study aimed at investigating the prevalence of these two factors in the pathological samples. Methods: Pathological samples of patients with osteosarcoma collected at a cancer surgery center between 2017 and 2018 were evaluated, of which 37 samples were included. The samples were evaluated using the IHC technique by two pathologists. Results: 12 women and 25 men with an average age of 26.7 years were studied. 21 patients (56.8%) developed metastases from the beginning or during follow-up, whereas 16 patients (43.2%) have not yet developed metastases. Regarding HER-2neu, 21 patients (56.8%) scored 0, 9 patients (24.3%) scored 1, 3 patients (8.1%) scored +2, and 4 patients (10.8%) scored +3. The VEGF intensity scores of 0, 1+, 2+, +3, +4 and were found in 7 (18.9%), 2 (5.4%), 18 (48.6%), 8 (21.6%), and 2 (5.4%) patients, respectively. The results of the study did not show a significant relationship between age, gender, metastasis, and positive expression rates of HER-2neu and VEGF. Conclusion: The high expression of VEGF (75.7%) in the studied samples should be considered and further studies on this biomarker in cases with osteosarcoma are recommended from different aspects. To achieve validated results and prove the results of this study, similar studies with a larger sample size should be performed, and using targeted therapy for angiogenesis in large scale trials should be considered.
