Multi-institutional randomized trial testing the utility of an interactive three-dimensional contouring atlas among radiation oncology residents.
The present study reports on the efficacy and usability of a web-based contouring atlas compared with those of existing contouring resources in a randomized trial. Compared with the residents using currently available resources, the residents using eContour had improved contour agreement with both the consensus and the expert contours for the high-risk clinical target volume and greater agreement with the expert contour for the contralateral parotid gland.

Application of electronic algorithms to improve diagnostic evaluation for bladder cancer.
The researchers evaluated the performance of electronic trigger algorithms to detect delays in hematuria follow-up. They concluded that triggers offer a promising method to detect delays in care of patients with high-grade hematuria and warrant further evaluation in clinical practice as a means to reduce delays in bladder cancer diagnosis.

Impact of a false-positive screening mammogram on subsequent screening behavior and stage at breast cancer diagnosis.
Researchers sought to examine the impact of a false positive (FP) screening mammogram on the subsequent screening mammography behavior. They found that experiencing a FP mammogram increases the risk of late stage at diagnosis compared with prior true negative (TN) mammogram Also, women with a FP mammogram were more likely to delay their subsequent screening compared with women with a TN mammogram.

More judicious use of expectant management for localized prostate cancer during the last 2 decades.
Urologists have been criticized for overtreating men with low risk prostate cancer and for passively observing older men with higher risk disease. Proponents of active surveillance for low risk disease and critics of watchful waiting for higher risk disease have advocated for more judicious use of observation. In this study, the investigator compared 2 population based cohorts to determine how expectant management has evolved during the last 2 decades.

Patient-reported barriers are associated with lower hepatocellular carcinoma surveillance rates in patients with cirrhosis.
This study characterized the association between hepatocellular carcinoma (HCC) surveillance receipt and patient knowledge, attitudes, and perceived barriers in a racially diverse and socioeconomically disadvantaged cohort of patients with cirrhosis. It found that patients with cirrhosis are knowledgeable and interested in HCC surveillance; however, patient-reported barriers are associated with lower surveillance rates in clinical practice and represent potential intervention targets to improve HCC surveillance effectiveness.

Inadequate utilization of diagnostic colonoscopy following abnormal FIT results in an integrated safety-net system.
The effectiveness of stool-based colorectal cancer (CRC) screening is contingent on colonoscopy completion in patients with an abnormal fecal immunochemical test (FIT). This study found that FIT positive patients never referred to gastroenterology or who missed their appointment after referrals were more likely to have comorbid conditions and documented illicit substance use compared with patients who completed a colonoscopy.

Reasons for lack of diagnostic colonoscopy after positive result on fecal immunochemical test in a safety-net health system.
This study aimed to characterize factors contributing to lack of follow-up colonoscopy in a racially diverse and socioeconomically disadvantaged cohort of patients with abnormal results on the fecal immunochemical test receiving care in an integrated safety-net health system. It concluded that lack of diagnostic evaluation is related to a combination of patient-, provider-, and system-level factors, highlighting the need for multilevel interventions to improve follow-up colonoscopy completion rates.
