Extensive intraduct component in invasive duct carcinoma of the breast: prevalence and significance in a south Asian setting.

ABSTRACT

Extensive intraduct component (EIC) in invasive duct carcinoma is one of the main factors affecting local cancer recurrence and thereby a major consideration in breast conserving therapy. A retrospective study was undertaken to assess the prevalence of extensive intraductal component in a South Asian setting. 105 cases of invasive duct carcinoma reported at a University Pathology Department during a 75 month period from January 1992, were reviewed. 48.6 percent of all cases assessed had an intraductal component. 13.3 percent had an EIC. Of the seventy-two T1 and T2 tumours reviewed 5.6 percent showed EIC. The results of this study indicate that by virtue of its low prevalence. EIC in infiltrating ductal cancer is unlikely to be a major obstacle in the decision of breast conserving therapy in the South Asian region.
