Background: The aim of this study was to measure the biological characteristics involved in tumorigenesis and the progression of breast cancer in symptomatic and screen-detected carcinomas to identify possible differences.
Methods: For this purpose, we evaluated clinical-pathological parameters and proliferative and apoptotic activities in a series of 130 symptomatic and 161 screen-detected tumors.
Results: After adjustment for the smaller size of the screen-detected carcinomas compared with symptomatic cancers, those detected in the screening program presented longer disease-free survival (RR = 0.
Introduction: This study evaluates clinical-pathological characteristics and survival rates associated with emergency admission and delays in diagnosis and treatment of 411 consecutive breast cancer patients.
Materials And Methods: Emergency admission and first symptom-first hospital visit delay were significantly associated with advanced tumor stages but only in the former case with short disease-free survival (RR 2.5, CI 95% 1.
