Evaluation of the Overall 5-Year Survival of Breast Cancer at INO: Data from the 5-Year Prospective Database

Background: Breast cancer is both the most common and deadliest cancer among women in the world. The objective of this study was to assess breast cancer survival rates. Material and Methods: Prospective study conducted at the National Institute of oncology (INO) Sidi Mohamed Ben Abdellah Rabat .diagnosed patients with cancer from 2013 to 2015. The date of inclusion in the study is the date of histological confirmation of cancer. The survival assessment performed by the Kaplan Meier method, and the comparison between the different classes of a variable was performed by the Log Rank test. Results: 931 cases were collected during this study. According to molecular classification 59% of luminal patients, 25% positive human epidermal growth factor receptors (her2 positive) and 16% basal. The percentage of survival at 5 years, for luminal stage I 93%, stage II 92%, stage III 74% and stage IV 25% ;as well as for basal stage I 92%, stage II 80%, stage III 53% and stage IV 10% ; then the her2 positive stage I 100%, stage II 75% and stage III 70%. Conclusion: The discovery of metastatic cancer decreased breast cancer survival rate, hence the importance of Early Detection Awareness.
