Introduction: Majority of breast cancer patients receive systemic therapy. This has led to an extensive search for effective factors to predict the outcome. Two such markers for breast cancer are Cluster of Differentiation 10 (CD10) and Vascular Endothelial Growth Factor (VEGF). There is limited data available in the literature to support these parameters in breast cancer patients, especially from the Indian subcontinent. Aim: To ascertain the association of pre-chemotherapy levels of CD10 and VEGF with tumour load in breast cancer and treatment response. Materials and Methods: A prospective cohort study was conducted in the Department of Surgery in collaboration with the Department of Pathology at Atal Bihari Vajpayee Institute of Medical Sciences and Dr. Ram Manohar Lohia Hospital, New Delhi, India, from November 2015 to February 2017. A total of 39 patients with Locally Advanced Breast Cancer (LABC) were included in the study. Preoperative levels of CD10 and VEGF were estimated in large needle core biopsy specimens. Standard anthracycline based chemotherapy was given to all patients as a 21 days cycle for three cycles. All patients underwent modified radical mastectomy after Neoadjuvant Chemotherapy (NACT). Levels of CD10 and VEGF were estimated again in the mastectomy specimen. Increase/decrease or no change in VEGF and CD10 expression percentage was ascertained for each patient after systemic therapy. Variables that were studied in the present study were Tumour, Nodes, and Metastasis (TNM) staging of patient, expression of VEGF and CD10 in large needle core biopsy specimens and its association with tumour load, response to NACT and its association with CD10 and VEGF and histopathological characteristics like presence or absence of lymphovascular invasion oestrogen, progesterone and Human Epidermal Growth factor Receptor 2 (HER2)/neu receptor status. Statistical analysis was done using the Statistical Package for Social Sciences (SPSS) version 22.0. Association between two ordinal variables was established using Kruskal-Wallis test. A comparison of ordinal paired data was done using Wilcoxon signed-rank sum test. The p-value <0.05 was taken as significant. Results: The mean age of study participants was 42.0±11.4 years. Increase in TNM staging lead to higher CD10 and VEGF expression (p-value<0.05 and <0.029, respectively). There was a significant reduction in CD10 and VEGF expression postchemotherapy (p-value<0.05). CD10 expression was found higher in subjects with ER-negative status (22 patients) with p-value=0.014 and HER2/neu positive status (19 patients) with p-value=0.028. Subjects with HER2/neu positive status had higher VEGF expression (20 patients) with p-value=0.032. Conclusion: CD10 and VEGF can be used as independent markers for indicating poor prognosis and can be used as target for development of novel therapies in carcinoma breast.
