Comparative Study
To What Extent Are Main Accident-Insurer Cases Representative of All Significantly Injured? A Swiss Monocenter Perspective.
Background and Objectives.-Even though Switzerland has a compulsory insurance system, there is a lack of detailed information on the treatment and outcome following trauma. The objective of this evaluation was to examine to what extent cases insured by the largest accident-insurer (Suva) are representative of all significantly injured. Methods.-Trauma center analysis of all ≥16 year old trauma patients with a New Injury Severity Score (NISS) ≥8, comparing the characteristics of Suva- vs non-Suva cases (chi-square; univariate explained variance R2; multivariate logistic regression analysis, Nagelkerke R2). ⋯ Conclusions.-Significantly injured patients in Switzerland may be considered comparable from a statistical point of view whether insured by the main accident-insurer or not, provided groups are adequately controlled for age and gender. Other differences appear to be only marginal. Respecting these limitations such data can justifiably be given as Swiss reference statistics and the relevant insurer outcome information used for international comparison.

Background and Importance.-Globally, almost one million new cases of stomach cancer were estimated to have occurred in 2012 (952,000 cases, 6.8% of the total), making it the fifth most common malignancy in the world, after lung, breast, colorectal, and prostate. Gastric cancer was the world's third leading cause of cancer mortality in 2012, responsible for 723,000 deaths, 8.8% of total cancer deaths. 1 In 2017, 28,000 new cases and 10,960 deaths are estimated for gastric cancer in the United States. 2 Estimated United States prevalence counts on January 1, 2014, for patients diagnosed within the previous 5-years was 48,271 (SEER Cancer Statistics Review-2014). Prognostic indices of survival & mortality in patients with gastric cancer are related to tumor stage including nodal involvement, direct tumor extension beyond the gastric wall, and wide-spread dissemination. ⋯ Mortality is a function of incidence and survival, and unfortunately, almost all of this decrease is due to the decrease in incidence of stomach cancer. Of the 157,258 invasive cases, 86.6% were clinically staged and 76.8% were histologically graded. Conclusions.-Given the histologic and etiologic heterogeneity of gastric cancer, major improvements in mortality and survival outcomes await the development of diagnostic markers for earlier diagnosis, and genomic sequencing and identification of chromosomal aberrations, nucleotide substitutions and epigenetic modifications that drive malignant transformation, for the development of targeted therapies for almost 200 gastric cancer subtypes.
