Introduction: Breast cancer is often diagnosed at a late stage in Tunisia with long delay in time to consultation and to diagnosis. The aim of the study was to identify explanatory factors to delayed diagnosis.
Methods: A case control analytical was performed from January 2013 to December 2014 in the department of Medical Oncology in FarhatHachedUniveristy Hospital.Patients with the diagnosis of ductal breast carcinoma were included in the study.Characteristics of a first group of 200 women with locally advanced or metastatic breast cancer (G1)were compared to a second group of 200 patients with early stage (G2).
Results: Median delay in consultation and mean tumor size were significantly more important in group G1 (p<0,001).A low level of schooling, a rural origin, poor socio-economic conditions and no encouragement by the patient relatives do not allow an early diagnosis.Misinterpretation of clinical breast signs was the only explanatory factor related to the system. In multivariate study, a low level of schooling(adjusted OR=2.72; CI 95% [1,65-4,49]), no encouragement by the patient's relatives(adjusted OR=7.86; CI 95% [4,24-14,57])and more than three dependants(adjusted OR=2.49; CI 95% [1,58-3,93]) were the independent factors that could explain the delay in diagnosis.
Conclusion: Our study confirm the inverse relationship between socio-economic and scholar level and disease stage. Health education campaigns particularly among women with a low schooling level and of rural origin could reduce time for consultation. Promoting continuing medical education could avoid diagnostic errors.

Background: Randomized clinical trials (RCTs) are fundamental to evidence-based medicine, but their real-world impact on clinical practice often remains unmonitored. Leveraging large-scale real-world data can enable systematic monitoring of RCT effects. We aimed to develop a reproducible framework using real-world data to assess how major RCTs influence medical practice, using two pivotal surgical RCTs in gynaecologic oncology as an example-the LACC (Laparoscopic Approach to Cervical Cancer) and LION (Lymphadenectomy in Ovarian Neoplasms) trials.

Background: Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer, characterized by frequent recurrence, metastasis, and poor survival outcomes despite chemotherapy-based treatments. This study aims to investigate the mechanisms by which Traditional Chinese Medicine (TCM) modulates the tumor immune microenvironment in TNBC, utilizing CiteSpace and bioinformatics analysis.
Methods: We employed CiteSpace to analyze treatment hotspots and key TCM formulations, followed by bioinformatics analysis to identify the main active components, targets, associated pathways, and their clinical implications in TNBC treatment.

Introduction: Breast cancer (BC) is the most prevalent malignant tumor in women, with triple-negative breast cancer (TNBC) showing the poorest prognosis among all subtypes. Glycosylation is increasingly recognized as a critical biomarker in the tumor microenvironment, particularly in BC. However, the glycosylation-related genes associated with TNBC have not yet been defined.
