About
The Revised International Staging System for Multiple Myeloma (R-ISS) is a prognostic scoring system used specifically for patients diagnosed with multiple myeloma. This calculator is designed to stratify patients into different risk groups based on various clinical and laboratory parameters, including serum albumin, beta-2 microglobulin, lactate dehydrogenase (LDH), and chromosomal abnormalities. The R-ISS is used to predict overall survival and progression-free survival, aiding clinicians in making informed decisions about treatment strategies and patient management. It is not applicable to patients with other types of cancer or those who lack the necessary laboratory data for calculation.
