Combined anti-HER2 and hormonal treatment in a patient with HRHER2 clear-cell uterine carcinoma: A case report.

Clear-cell carcinoma (CCC) of the uterus is an aggressive disease. Current international guidelines on the treatment of uterine carcinomas predominantly cover cancer with endometrioid histology, and clinicians tend to use the same approach for patients with non-endometrioid histology due to the absence of separate guidelines for these rare tumor types. At present, molecular analysis enables the assessment of novel and non-standard treatment options based on the individual characteristics of a tumor.
