Uterine Leiomyosarcoma nomogram: 5 year overall survivall
Current model is an externally validated nomogram predicting the five-year overall survival in patients with Uterine Leiomyosarcoma. 

Note: This model calculates the nomogram published in the original article (see files & references) and may be deviant from the MSKCC web-calculator as the full cox-regression formula is not provided.

    Additional information

    During the study period, 270 patients presented with pathologically confirmed uterine leiomyosarcoma. Patients with 1 or more missing nomogram values (n = 85) were excluded, leaving 185 patients for the nomogram analysis. There were no significant differences between the whole cohort (n = 270) and the nomogram cohort (n = 185) with regard to follow-up, median OS, and clinical characteristics. There was no statistically significant difference in OS between patients who received no further treatment versus those who received any type of postresection treatment. In addition, there was no statistically significant difference in stage-specific OS (by either FIGO or AJCC) between patients who received no further treatment versus those who received any type of postresection treatment.

    Result interpretation

    Results from the external validation study showed that the nomogram concordance index was 0.67(SE=0.02), which was as high as the concordance index from the initial cohort used for nomogram development. The concordance between actual overall survival and nomogram predictions suggests excellent calibration since predictions were within 1% of actual 5-year overall survival rates for patients with a predicted 5-year OS of less than 0.68.
