Introduction: Breast cancer is the most common cancer among women and a leading cause of cancer-related deaths. Prognosis plays a crucial role in understanding the course of the disease and determining appropriate treatment. The Nottingham Prognostic Index (NPI) is a clinically relevant and internationally validated tool for classifying breast cancer cases. Additionally, breast cancer can be classified based on the expression of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and triple-negative breast cancer (TNBC). This study aimed to investigate the relationship between breast cancer subtypes and NPI in terms of recurrence-free survival in patients at Dr. Sardjito Hospital.
Method: This retrospective cohort study included breast cancer patients aged <70>
Results and Discussion: The study included 304 patients with a mean age of 53.67 ± 10.74 years. The median recurrence-free survival period was 24 months. The mean NPI score was 6.04 ± 1.29. The most common breast cancer subtypes observed were PR-positive in 33.2% of patients, followed by HER2-positive in 27.3%, ER-positive in 23.0%, and TNBC in 16.5%. Spearman's analysis revealed a significant correlation between recurrence-free survival and NPI scores but not with breast cancer subtypes. The TNBC subtype showed the lowest survival rate, with only 54% of patients surviving, while the PR subtype had the longest average recurrence-free survival of 8.6 months, and the ER subtype had the shortest average of 7.9 months. However, no significant differences were found between the subtypes. Moderate and poor NPI scores were associated with lower recurrence-free rates across all cancer subtypes, with significant differences observed only in the PR subtype.
Conclusions: The study found a significant association between recurrence-free survival and Nottingham Prognostic Index (NPI) scores but not with breast cancer subtypes. The category with the lowest survival scores was the "poor" category (NPI >5.4), while the TNBC subtype had the lowest survival rate. These findings highlight the importance of considering NPI scores for prognosis assessment in breast cancer patients.
