The clinical significance of abnormally high levels of carbohydrate antigen (CA) 19-9 after resection of biliary tract cancer (BTC) is not well established. The aim of this study was to determine the prognostic value of CA19-9 normalization in patients undergoing resection of BTC with curative intent. ⋯ Non-normalization of CA19-9 level after resection of BTC with curative intent was associated with worse OS. R1 resection was associated with a particularly poor prognosis when CA19-9 levels did not normalize.

Randomized Controlled Trial Comparative Study
Randomized trial of Roux-en-Y gastric bypass versus sleeve gastrectomy in achieving excess weight loss.
Robust data on quality of life (QoL) after different techniques of bariatric surgery are sparse. This RCT compared excess weight loss (EWL) and QoL after sleeve gastrectomy versus Roux-en-Y gastric bypass (RYGB). ⋯ RYGB and sleeve gastrectomy resulted in equivalent, long-standing QoL improvement. RYGB resulted in more stable weight loss but was associated with higher readmission rates. Registration number: NCT02475590.

Many patients with rectal cancer receive radiotherapy (RT) to reduce the risk of local recurrence. Radiation may give rise to adverse effects, including second primary cancers. In view of the divergent results of previous studies, the present study evaluated the risk of second primary cancer following RT in all randomized RT rectal cancer trials conducted in Sweden and in the Swedish ColoRectal Cancer Registry (SCRCR). ⋯ Overall, there was no increased risk of second primary cancer following RT for rectal cancer within or outside of the irradiated volume up to 20 years of follow-up. Men with rectal cancer who received RT had a reduced risk of prostate cancer.
