information and communication technology (ICT)
electronic data collection (EDC) electronic patient records (EPR) clinical-data-management systems (CDMS) European Standard Operating Procedures of El
ectrochemotherapy and Electrogenetherapy (ESOPE)
case report forms (CRFs)
DesignDesign
centralized database development of an application for easy data su
bmission to the central database computer- and platform-independent solution; remote-application maintenance and upgrading application must work or be accessible inside t
he clinical network respecting the “privacy” and ownership of eac
h medical center’s data
..
..
Data storedData stored
patient data (demography, medical history, physical examination, etc.);
therapy data (sessions, evaluation visits, follow-up visits, etc.);
data from the local databases of Cliniporator medical devices;
digital images of tumor nodules in different phases of therapy and follow up
WEB-BASED EDC APPLICATION
web forms (digital CRF) for data entry; upload of images interactive human map for marking tumor loca
tions; local MDB database upload from the Clinipora
tor medical device; basic online statistics; interactive tumor-history graph
Upload of Images

Basic Online Statistics
number of treated patients per center number of ended therapies number of tumor treatments uploaded corresponding local databases distribution of applications of different electro
de types different drugs used
Interactive Tumor-History Graph
interactive Flash presentation of the tumor history for each patient in the database
Each timeline is accompanied by data of tumor initial size and location, therapy, drug, and pulse parameters, as well as tumor images
SECURITY MEASURES
server level; Data transmission level; application level
DATA QUALITY AND DATA ANALYSIS
It is too optimistic to expect that all the data are entered correctly
Check table form-completeness-notification for the statistical analysis, the most suitable for
m of data representation is a “flat table” (one single table with all the required data included in it).
They did not agree on the advantages of Web-based medical-record system over the usual (non-Web based) computer medical-record system. Nevertheless, all the users agreed that an obvious advantage of this system was the support of multimedia content
ConclusionConclusion
The Internet technology fills the gap between application development and deployment
Users/researchers can promptly shape the application design and functionalities
