Practical Experience with a Contextual Map Service

A year ago, the development of a Contextual Map Service called Sissi began. As it has been introduced in previous research articles, the purpose of this service, which is based on the OGC WMS specification, is to implement the idea of contextual cartographic visualisation into the web environment. Today, we have the first functional prototype of Sissi, which was tested in November 2008 during a field experiment called ‘Transport of Dangerous Goods II’.

Clinical Stages in Patients with Primary and Subsequent Cancers Based on the Czech Cancer Registry 1976–2005

Of 1,486,984 new cancers registered in the Czech Cancer Registry in 1976-2005, 290,312 (19.5%) were multiple malignant neoplasms (MMNs), of which there were 65,292 primary and 89,796 subsequent cases in men and 59,970 primary and 75,254 subsequent cases in women. The duplicities were higher in women, and the triplicities and others (3–6 MMNs) were higher in men. The most frequent diagnoses were the primary cancers of skin, gastrointestinal and urinary tract, male genital organs, respiratory tract in men, and cancers of skin, breast, female genital organs, and gastrointestinal tract in women. The analysis of the early and advanced clinical stages shows that the number of subsequent advanced stages increased after primary advanced stages. Their time-age-space distributions visualized maps of MMNs in 14 Czech regions. These results support the improvement of algorithms of dispensary care for the early detection of the subsequent neoplasms.
