Randomized Controlled Trial Multicenter Study Comparative StudyParticipation and yield of colonoscopy versus non-cathartic CT colonography in population-based screening for colorectal cancer: a randomised controlled trial.
Screening for colorectal cancer is widely recommended, but the preferred strategy remains unidentified. We aimed to compare participation and diagnostic yield between screening with colonoscopy and with non-cathartic CT colonography. ⋯ Netherlands Organisation for Health Research and Development, Centre for Translational Molecular Medicine, and the Nuts Ohra Foundation.

ReviewEGFR exon 20 insertion mutations in non-small-cell lung cancer: preclinical data and clinical implications.
Lung cancer is the leading cause of cancer-related death. The identification of epidermal growth factor receptor (EGFR) somatic mutations defined a new, molecularly classified subgroup of non-small-cell lung cancer (NSCLC). Classic EGFR activating mutations, such as inframe deletions in exon 19 or the Leu858Arg (L858R) point mutation in exon 21 are associated with sensitivity to first generation quinazoline reversible EGFR tyrosine kinase inhibitors (TKIs). ⋯ Growing clinical experience with patients whose tumours harbour EGFR exon 20 insertions corresponds with the preclinical data; very few patients have had responses to EGFR TKIs. Despite the prevalence and biological importance of EEGFR exon 20 insertions, few reports have summarised all preclinical and clinical data on these mutations. Here, we review the literature and provide an update with an emphasis on the structural, molecular, and clinical implications of EGFR exon 20 insertions.

Randomized Controlled TrialHuman papillomavirus testing for the detection of high-grade cervical intraepithelial neoplasia and cancer: final results of the POBASCAM randomised controlled trial.
Human papillomavirus (HPV) testing is more sensitive for the detection of high-grade cervical lesions than is cytology, but detection of HPV by DNA screening in two screening rounds 5 years apart has not been assessed. The aim of this study was to assess whether HPV DNA testing in the first screen decreases detection of cervical intraepithelial neoplasia (CIN) grade 3 or worse, CIN grade 2 or worse, and cervical cancer in the second screening. ⋯ Zorg Onderzoek Nederland (Netherlands Organisation for Health Research and Development).
