  • According to SEER, the

mortality associated with y uterine cancer has almost doubled over the past 20 years and has been associated with and has been associated with a steady increase in the incidence of disease

Access to Care and Equivalency of Treatment q y

  • Conflicting reports regarding inequalities in frequency of hysterectomy
  • No apparent racial disparities in referral to gynecologic oncologist for

management

  • Adjuvant radiation and chemotherapy found to be similar in population

Racial Disparities in T S d Hi l Tumor Stage and Histology

  • Blacks are less likely to present with endometrioid histology and more likely
  • Blacks are less likely to present with endometrioid histology and more likely

to present with less favorable histologic subtypes (i.e. serous, clear cell, etc)

  • Blacks present more often with regional or systemic metastasis than Whites

  • Undifferentiated histology more often found in Blacks compared to Whites

  • A 1.6-Mbp region of gain at 1q23

was identified by aCGH in all Black patients and high grade Whit ti t b t t Whit l White patients, but not White low grade patients.

  • The number of Blacks in the

validation set was too small to validation set was too small to confirm the CGH association with racial disparity Morrison et al: Genes, Chromosomes and Cancer 2010;49:791-802

Phosphoserine Phosphatase Like (PSPHL)

  • PSPH identified on Affy could not

be internally validated be internally validated

  • We acknowledged that PSPHL

shares homology with PSPH and is the differentially expressed transcript by race

  • PSPHL increased in ovarian

cancer from Blacks compared to Whites Whites

  • PSPHL increased in normal

endometrium and normal ovary from Blacks compared to Whites from Blacks compared to Whites Ferguson et al: Gynecol Oncol 2006;101:209-13 Risinger et al: Front Oncol 2012;2:1-15

  • Differences noted in early stage cancers but not

advanced stage cancers with internal validation and consistency with published data consistency with published data
