Soft Tissue Sarcoma: Prediction Tools

Our sarcoma nomograms are online prediction tools that can calculate probabilities of survival and disease recurrence based on specific information about the patient and the tumor. These tools can help sarcoma patients and their physicians decide among treatment choices.

Synovial Sarcoma Survival Nomogram

Our synovial sarcoma survival nomogram can be used to predict the probability of a person surviving three years and five years after being diagnosed with synovial sarcoma. The tool was developed only for patients who have synovial sarcoma.

In order for this tool to provide an accurate prediction, you will need to include accurate values for all of the information below:

  • Tumor site: Whether the primary tumor is located in the upper extremity, lower extremity, or elsewhere (other sites).
  • Tumor size: The largest diameter of the primary tumor, which may be entered as a number from 1 cm to 30 cm.
  • Tumor depth: Whether the tumor is superficial or deep.
  • Variant: Whether the tumor variant (subtype) is biphasic or monophasic.

Liposarcoma Survival Nomogram

Our liposarcoma survival nomogram can be used to predict the probability of surviving five years and 12 years after surgery, based on which one of five specific liposarcoma subtypes the patient has, combined with other factors.

In order for this tool to provide an accurate prediction, you will need to include accurate values for all of the information below:

  • Age: Patient’s age at the time of surgery.
  • Gender: Male or female.
  • Histologic variant (subtype): Whether the tumor was well-differentiated, myxoid, dedifferentiated, 5 to 25 percent round cell, more than 25 percent round cell, or pleomorphic.
  • Margins: Whether the patient had a complete excision with negative margins (R0), a complete excision with positive margins (R1), or an incomplete excision with gross residual disease (R2).
  • Presentation status: Whether the patient had undergone a previous core or incisional biopsy, had received no prior surgical treatment or biopsy, or had prior excisional biopsy of the entire tumor.
  • Primary site: Whether the primary tumor was located in the lower extremity, the upper extremity, the trunk, the retroperitoneum without contiguous (adjacent) organ resection, or the retroperitoneum with contiguous (adjacent) organ resection.
  • Tumor burden: The sum of the maximum diameters of the primary tumor (in centimeters).
  • Tumor depth: Whether the tumor was superficial or deep.

Local Recurrence Risk after Limb-Sparing Surgery without Radiation Nomogram

Our local recurrence risk after limb-sparing surgery without radiation nomogram can be used to predict the probability 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 is calculated for both three years and five years after surgery.

In order for this nomogram to provide an accurate prediction, you need to include accurate values for all of the categories below:

  • Age: Whether the patient is 50 or younger, or older than 50.
  • Tumor size: Whether the largest diameter of the primary tumor is 5 cm or less, or more than 5 cm.
  • Margin: Whether the tumor margin was
    • Negative
    • Positive or close.
  • Tumor grade: Whether the tumor was low grade or high grade.
  • Histology: Whether your tumor was classified as
    • Atypical lipomatous tumor (ALT), also known as Well-differentiated liposarcoma (Well-diff lipo)
    • Another sarcoma type.
