Spleen size is significantly influenced by body height and gender. The Splenocalc App is designed to calculate approximate percentiles of an individual´s spleen size. The algorithm of the Splenocalc App is based on the height- and gender-corrected normal values for homeostatic spleen length and volume (for women between 155 and 179 cm and men between 165 and 199 cm body height), the Splenocalc App is performing these calculations and is providing additional information.
SARCULATOR
This medical tool provides physicians with predictive models for retroperitoneal and extremity sarcoma patients. It estimates overall survival and disease-free survival, serving as an informative resource to enhance physician predictive capabilities.
- Predictive models for sarcoma patients
- Estimates 5-year overall survival
- Estimates 5-year disease-free survival
- Estimates 10-year overall survival
- Estimates cumulative incidence of distant metastasis
- Informative tool for physicians

This app is meant to be used only by physicians and it is not meant to make clinical decisions (the clinical usefulness of the two models has not been tested) but to be used as an informative tool to improve the predictive capability of a physician. Two kinds of predictions are possible: - RPS: 5-year overall survival (OS) and 5-year disease-free survival (DFS) in primary resected retroperitoneal sarcoma (RPS) patients. . - ESTS: 5- and 10-year overall survival (OS) and cumulative incidence of distant metastasis (CCI of DM) in primary resected extremity STS patients.
