To determine the relationship between negative margin width and locoregional recurrence (LRR) in a contemporary cohort of ductal carcinoma in situ (DCIS) patients. ⋯ Routine additional surgery may not be justified for patients with negative margins <2 mm who undergo RT but should be performed in patients who forego RT.

RAS Mutation Clinical Risk Score to Predict Survival After Resection of Colorectal Liver Metastases.
To determine the impact of RAS mutation status on the traditional clinical score (t-CS) to predict survival after resection of colorectal liver metastases (CLM). ⋯ Modifying the t-CS by replacing disease-free interval, number of metastases, and CEA level with RAS mutation status produced an m-CS that outperformed the t-CS. The m-CS is therefore a simple validated tool that predicts survival after resection of CLM.

Targeting Value-Driven Quality Improvement for Laparoscopic Cholecystectomy in Michigan.
The purpose of this study was to evaluate complete episode expenditures for laparoscopic cholecystectomy, a common and lower-risk operation, to characterize novel targets for value-based quality improvement. ⋯ Episode payments for laparoscopic cholecystectomy vary widely across surgeons. Although improvements in several domains would reduce expenditures, efforts to expand ambulatory surgical practices may result in the largest savings to beneficiaries in Michigan.
