Results: In this study, majority of the cases were in grade 1 and in Stage II. Continuous data were represented as mean and standard deviation. Chi-square test or Fischer's exact test (for 2 × 2 tables only) was used as a test of significance for qualitative data. Statistics: Categorical data were represented in the form of frequencies and proportions. We restaged all the cases as per the prognostic staging system (8 th AJCC) and calculated the survival status with NPI as long-term (5-year survival status) follow-up of the cases was not possible. Settings and Design: In this retrospective study, we collected the clinical and pathological data from 56 IDC cases from January 2019 to June 2021 presenting at our institute. Aims: The aim is to evaluate the stage migration between the 7 th and 8 th edition AJCC in IDC of the breast and compare both staging systems with the NPI prognostic scoring system. Hence, the present study aimed to analyze the stage migration from 7 th to 8 th edition AJCC staging in infiltrating ductal carcinoma (IDC) and comparison of each staging system with the Nottingham prognostic index (NPI) prognostic scoring system. There has been a recent change in the staging of breast cancer, from the 7 th edition to 8 th edition AJCC. Source of Support: None, Conflict of Interest: NoneĬontext: The American Joint Committee on Cancer (AJCC) staging system is a very important prognostic factor for treating patients with carcinoma breast.
