Comparing CD10 Expression With the Clinicopathological Features and Hormone Status of Invasive Breast Cancer.

Background Worldwide, female breast cancer is the most common cancer (11.7%), followed by lung (11.4%), colorectal, prostate, and stomach. Breast cancer is the fifth most common cause of cancer-related mortality, with lung cancer being the leading cause. In India, breast and cervical cancers are the two most common cancers among women. This study was undertaken to analyse the expression of CD10 in invasive duct cancer (IDC) and its correlation with the various clinicopathological features and hormone status. Materials and methods This study was conducted in the Department of Pathology, Saveetha Medical College and Hospital on 42 cases of invasive ductal carcinoma - no special type (IDC NST). The clinical and histopathologic parameters such as age, tumor site, tumor size, histologic type, histologic grade, lymph node metastases, lymphovascular invasion, and perineural invasion were assessed in hematoxylin and eosin-stained sections of the tumor tissue along with the hormone status of positivity for ER, PR and Her2Neu. These parameters were subsequently compared with the expression of CD10 in the corresponding slides and statsitical correlation was done using the chi square test. Results The most common age group was more than 40 years, with 41-50 years, and 51-60 years in particular. CD10 was positive in 93% of cases. There was a positive correlation between CD 10 expression and lymphovascular invasion in the study (p-0.006). There was no significant relationship between hormone status and CD10 expression. Conclusion A significant association was seen between CD10 expression and lymphovascular invasion. No relation was found between CD10 and the other parameters such as tumour grade, lymph node metastases, lymphovascular invasion, perineural invasion and hormone status. Further studies are required to explore the potential of CD10 as a prognostic marker for IDC.
