Are There Breast Cancer Patients with Node-Negative Small Tumours, Who Do Not Benefit from Adjuvant Systemic Therapy?

Objective: To identify subgroups of patients with pT1 pN0 breast cancer (BC) who might not profit from adjuvant systemic therapy (AST).

Methods: Data of 3,774 pT1 pN0 BC patients from 17 certified BC centres within the BRENDA study group were collected between 1992 and 2008 and retrospectively analysed. Uni- and multivariate analyses were performed using Kaplan-Meier methods and Cox regression models.

Guidelines are advantageous, though not essential for improved survival among breast cancer patients.

The purpose of this retrospective multicenter study was to resolve the pseudo-paradox that the clinical outcome of women affected by breast cancer has improved during the last 20 years irrespective of whether they were treated in accordance with clinical guidelines or not. This retrospective German multicenter study included 9061 patients with primary breast cancer recruited from 1991 to 2009. We formed subgroups for the time intervals 1991-2000 (TI1) and 2001-2009 (TI2).

Clinical criteria replenish high-sensitive troponin and inflammatory markers in the stratification of patients with suspected acute coronary syndrome.

Objectives: In patients with suspected acute coronary syndrome (ACS), rapid triage is essential. The aim of this study was to establish a tool for risk prediction of 30-day cardiac events (CE) on admission. 30-day cardiac events (CE) were defined as early coronary revascularization, subsequent myocardial infarction, or cardiovascular death within 30 days.
