Meta analysis cancer

Willem Oosterlinck, Karel Decaestecker
Non-muscle-invasive bladder cancer (NMIBC) is a highly recurrent disease. Early bladder chemotherapy instillation (EBCI) after transurethral resection (TURB) is an efficient way to diminish recurrence. However, this method is often challenged. Areas covered: There was a recent publication of a large meta-analysis with the original patient data and the largest study ever on EBCI. Both brought new evidence on EBCI. Also the results of the 2 trials of EBCI with apaziquone appeared. EBCI is discussed among other methods to decrease recurrence...

Regular screening for gastric cancer (GC) is based on invasive upper gastrointestinal (GI) endoscopy and is limited to few high incidence countries. As GC is a major cause of cancer death worldwide, a non-invasive, simple screening test is of value. We assessed the prevalence of preclinical GC and the corresponding numbers needed to screen (NNS) to detect GC cases both without and with preselection using breath tests from the literature in various populations. 
 Methods: Using age- and sex-specific GC incidence data and transition rates from preclinical to clinical GC, we estimated prevalences of preclinical GC worldwide in the populations aged 50-74 years, and we evaluated the accuracy of breath testing for GC detection based on published studies...

PURPOSE: Evidence on the effect of vasectomy on prostate cancer is conflicting, with the issue of detection bias a key criticism. We examine the effect of vasectomy reversal on prostate cancer risk in a cohort of vasectomised men; evidence of a protective effect would be consistent with a harmful effect of vasectomy on prostate cancer risk, while nullifying the issue of detection bias. METHODS: Data were sourced from five population-level linked health databases located in Australia, Canada and the United Kingdom...

Background: Cancer and death are the most severe outcomes that affect patients with inflammatory bowel disease (IBD). These outcomes are even more severe if they occur at a young age but are rare, even in the general population. We conducted a systematic review to provide an overview of all reported pediatric (PIBD) patients with severe outcome. Methods: A literature search identified publications that reported development of cancer or fatal outcome in PIBD patients...

Approximately 75% of patients with pancreatic ductal adenocarcinoma are diagnosed with advanced cancer, which cannot be safely resected. The most commonly used biomarker CA19-9 has inadequate sensitivity and specificity for early detection, which we define as Stage I/II cancers. Therefore, progress in next-generation biomarkers is greatly needed. Recent reports have validated a number of biomarkers, including combination assays of proteins and DNA mutations; however, the history of translating promising biomarkers to clinical utility suggests that several major hurdles require careful consideration by the medical community...
