Posthepatectomy liver failure (PHLF) is a rare but dreaded complication. The aim was to test whether a combination of non-invasive biomarkers (NIBs) and CT data could predict the risk of PHLF in patients who underwent resection of hepatocellular carcinoma (HCC). ⋯ The NIB model provides reliable preoperative evaluation with performance at least similar to that of invasive methods for PHLF risk prediction.

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.

The impact of weight loss induced by bariatric surgery on cancer occurrence is controversial. To study the causal effect of bariatric surgery on cancer risk from an observational database, a target-trial emulation technique was used to mimic an RCT. ⋯ When emulating a target trial from observational data, a reduction of 11 per cent in obesity-related cancer was found after bariatric surgery.
