The RadOnc Toolbox is a resource for health care professionals that is designed to support evidence-based practice. This point-of-care tool compiles frequently accessed references related to the delivery of radiation therapy, including dose constraints, calculators, clinical practice guidelines, staging, and other oncology resources. The RadOnc Toolbox was created by Malolan Rajagopalan, MD, MBA, who was Principal Investigator of a grant from the ASTRO Foundation, then known as the Radiation Oncology Institute (ROI), that aimed to develop a resource to manage acute and late radiation toxicity. The Foundation assumed responsibility for the RadOnc Toolbox and released the first version in 2016. Since then, the Foundation has continued to add resources and enhance the content. The redesigned RadOnc Toolbox released by the Foundation in 2023 is produced in collaboration with Red Canvas, LLC.

- 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.
