ABSTRACT
<b>Background and Objective:</b> Angiogenesis is a mechanism by which new blood vessels are developed in healing and tumour tissues, where it is necessary for regeneration growth, tumour cells survival and metastasis. This study aimed to assess the angiogenesis mechanism among Sudanese females with breast cancer using anti-CD34 and anti-CD105 markers. <b>Materials and Methods:</b> Three hundred female representative Formalin-Fixed Paraffin-Embedded (FFPE) breast tissue blocks were included in this study. Of the 300 representative tissue blocks, 200 were breast cancer patient’s tissues (confirmed cases) and 100 were normal breast tissues (controls). Their ages mean±SD, 47.3±12.9 years. <b>Results:</b> The results showed the MVD of CD34 significantly increased in malignant lesions as compared to normal breast tissues. The mean of MVD CD34 and MVD CD105 showed statistical differences among different histologic types of breast cancer. Also, a strong positive correlation was detected between the manual and automated MVD counting methods. Also, the current study revealed no significant differences were observed in mean MVD counting for both markers and menopausal status or the age groups of the study population. <b>Conclusion:</b> The MVD is a good tool for assessing prognostic markers. The CD105 marker has a high specificity to the new evolving tumour vessels and is a useful predictor for angiogenesis and breast cancer metastasis.
