Background: The current standard for the preoperative marking of non-palpable breast lesions is wire guided localization (WGL) which is associated with logistical efforts and patient discomfort. Non-radioactive seeds (NRS) recently challenged the use of WGL; but do they provide a better alternative from a logistical and environmental perspective?
Methods: WGL standard was compared with NRS available in Germany: Magseed®, Pintuition®, SAVI SCOUT ® and LOCalizer™ on a logistical and carbon-footprinting basis. In the logistical analysis the number of patient contacts with the healthcare system for lesion localization/removal and the number of breast punctures were evaluated in two different clinical scenarios (primary surgery and secondary surgery after neoadjuvant treatment).
Background: Although adequate physical activity has been shown to be beneficial in early breast cancer, evidence in metastatic breast cancer is sparse and contradictory, which could be related to distinct effects of physical activity on the different molecular cancer subtypes. Therefore, we here evaluated the effect of physical activity on progression-free and overall survival (PFS, OS) in metastatic breast cancer, specifically looking at molecular subtypes.
Methods: International Physical Activity Questionnaire (IPAQ) questionnaires, filled out by patients enrolled in the prospective PRAEGNANT registry (NCT02338167; n = 1,270) were used to calculate metabolic equivalent task (MET) minutes, which were subsequently categorized into low (n = 138), moderate (n = 995) or high IPAQ categories (n = 137).
