Type II endometrial carcinoma, sarcoma and carcinosarcoma account for 10% of uterine malignancies but 50% of recurrences. Survival at recurrence is poor and better
prognostic markers are needed to guide therapy. The prognostic significance of the novel markers clusterin and tetraspanin CD151 were evaluated in a cohort of poor
outcome endometrial malignancies, along with oestrogen receptor, progesterone receptor, p53 and human epidermal growth factor receptor 2. Immunohistochemistry profiles and survival outcome between grade 3 endometroid cancers and type 2 cancers were compared.
Material and Methods:
Tissue microarrays constructed from 156 poor outcome uterine malignancies, tested with immunohistochemistry and staining were correlated with clinicopathological, mortality and survival data.
Expression of CD151 was significantly higher in uterine papillary serous and clear cell carcinoma (USPC+CC) compared to grade 3 endometrioid carcinoma, sarcoma or carcinosarcoma. All other markers were not prognostic for survival. Except for CD151, there was no significant difference in marker positivity, age, stage or survival between G3 EEC and UPSC+CC.
CD151 is a novel marker in type 2 cancers that may guide therapeutic decisions. These data also suggest that grade 3 EEC is better characterised as a type II endometrial cancer
and may benefit from similar treatment.
