A prognosis based classification of undifferentiated uterine sarcomas: Identification of mitotic index, hormone receptors and YWHAE-FAM22 translocation status as predictors of survival

Undifferentiated uterine sarcomas (UUS) are rare tumors with a heterologous biology and a poor prognosis.

In a recent study by scientists from the Human Protein Atlas project and colleagues, the relevance of clinicopathology, mitotic index, translocation status (YWHAE-FAM22), and a number of biomarker candidates were examined for correlation with the prognosis of these tumors. The protein biomarkers P53, P16, Ki-67, Cyclin-D1, ER, PR, and ANLN were evaluated by immunohistochemistry.

Although the number of cases was small, these results indicate that UUS can be divided into two prognostic groups with a statistically significant difference in prognosis:

  • a high mitotic index group (10 cases)
  • a low mitotic index group (16 cases)

    The mitotic index was used as primary criteria for classification, followed by expression of either ER, PR, or the presence of a YWHAE-FAM22 translocation as a secondary criteria. The expression of ER, PR, or presence of the YWHAE-FAM22 translocation correlated with low mitotic index and an additionally improved prognosis.

    This study demonstrates the presence of statistically significant prognostic subgroups within UUS, and provides treatment insights.
