Extremity Sarcoma: Risk of Local Recurrence After Limb-Sparing Surgery Without Radiation

Our sarcoma local recurrence nomogram is a tool designed to predict the likelihood of soft tissue sarcoma returning at the site of initial surgery after the tumor is removed through limb-sparing surgery if the patient does NOT receive radiation. The probability of local recurrence is calculated for both three years and five years after surgery.

Results produced by this tool are based on data from patients treated at MSK, a large research institution with surgeons who perform a high volume of soft tissue sarcoma procedures. All results must be understood in the context of each patient’s specific treatment plan. Patients and caregivers using this tool should discuss the result with the patient’s physician.

To gather the information required to use this nomogram, use our worksheet.

All fields are required unless noted optional
What are surgical margins?
Margin refers to the edge or border of the tissue removed in cancer surgery. The margin is described as negative or clear when the pathologist finds no cancer cells at the edge of the tissue, suggesting that all of the cancer has been removed. The margin is described as positive or close when the pathologist finds cancer cells at the edge of the tissue or within 1 mm of the tumor margin.
What is grade?
Tumor grade refers to the extent of abnormality of the cells when viewed under the microscope. “Low-grade” cells look normal and grow slowly; “high-grade” cells look abnormal and grow more quickly than low-grade cells.
What is histology?
Histology refers to the exact type of cancer based on examination of the tumor tissue under the microscope.
