Table 1 Risks for endometrial cancer in heterozygotes of each path_MMR gene, 10-year survival, and mortality within 10 years.

From: Risk-reducing hysterectomy and bilateral salpingo-oophorectomy in female heterozygotes of pathogenic mismatch repair variants: a Prospective Lynch Syndrome Database report

Age group

Risk of endometrial cancer diagnosed in the age interval for a heterozygote without cancer at or before entry to the age group

10-year survival

Risk of endometrial cancer diagnosed in the age interval indicated and dying of this within 10 years, for a heterozygote without previous cancer at or before entry to the age group

  1. To the left: the upper four rows indicate risk for endometrial cancer from 25 to 40, 50, 60, or 70 years of age, respectively, if hysterectomy is not undertaken before the ages indicated (i.e., the risk for cancers that could have been prevented by hysterectomy at age 25). The middle three rows indicate the risk for heterozygotes from 40, 50, or 60 years of age, respectively, up to 70 years of age, for cancers that could be prevented by hysterectomy at age 40, 50, or 60 years of age, respectively. The lower two rows indicate the risk for heterozygotes in the age intervals indicated, for cancers that could be prevented by hysterectomy at age 40 or 50, respectively.
