The Clinical Treatment Score post-5 years (CTS5) integrates four clinicopathological variables to estimate the residual disease recurrence risk in hormone receptor-positive breast cancer patients who have been treated with five years of adjuvant endocrine therapy. This study aimed to determine the accuracy of the CTS5. ⋯ The CTS5 can predict late distant recurrence risk in pre- and postmenopausal hormone receptor-positive breast cancer patients. CTS5 overestimates the risk for high-risk patients and thus, its use in these patients warrants caution.

Randomized Controlled Trial
Extended-course antibiotic prophylaxis in lower limb amputation: randomized clinical trial.
Lower limb amputation (LLA) is typically described as 'clean surgery', but surgical-site infection (SSI) rates are high and there is significant variation in antibiotic prophylaxis practice. This study aimed to determine whether an extended period of antibiotic prophylaxis (5-day course) is superior to a short course (24 h) in preventing SSI in patients undergoing minor and major LLA. ⋯ SSI and IWH are common after LLA and have a significant impact on outcome. A 5-day course of antibiotic prophylaxis was associated with a reduction in both SSI and IWH compared with a 24-h course, and this reduced the need for further surgery. Registration number: NCT02018094 (http://www.clinicaltrials.gov); EudraCT 2012-003146-32 (https://www.clinicaltrialsregister.eu).

Oesophageal adenocarcinoma poses a significant global health burden, yet the staging used to predict survival has limited ability to stratify patients by outcome. This study aimed to identify published clinical models that predict survival in oesophageal adenocarcinoma and to evaluate them using an independent international multicentre dataset. ⋯ This study highlights the need to concentrate on robust methodologies and improved, independent, validation, to increase the likelihood of clinical adoption of survival predictions models.
