To evaluate the reliability and validity of histopathological breast cancer diagnoses following an observed 44% five-year survival rate in a patient cohort.
Histological slides from 136 mammary carcinoma cases were reviewed independently by three pathologists.
Pathologists reached unanimous diagnostic agreement (either all positive or all negative for carcinoma) in 130 of 136 cases (95.6%).
The high inter-observer consistency validates the accuracy of the histopathological evaluations and confirms the authenticity of the reported 44% five-year survival rate.
