Controversies in the management of clear cell carcinoma of the uterus and ovary
6Citations
Clear cell ovarian and endometrial carcinomas are rare and aggressive gynecologic malignancies that present unique challenges owing to their underrepresentation in clinical trials and limited prospective data. In this report, we aimed to explore 3 major controversies in the management of clear cell ovarian and endometrial carcinomas, highlighting areas that require further investigation. First, we addressed the unique phenotypic characteristics of clear cell ovarian carcinoma and clear cell endometrial carcinoma and whether they should be considered a unified disease entity or a distinct disease. Recent trials grouped these carcinomas, potentially expanding their therapeutic options. However, emerging molecular data underscores the significant differences between clear cell ovarian carcinoma and clear cell endometrial carcinoma, raising questions regarding this combined approach. This distinction is critical in guiding tailored treatment strategies. Second, we examined the management of localized diseases. Although early-stage diagnoses are common in clear cell carcinomas, optimal surgical and adjuvant treatment strategies remain uncertain. Current practice often relies on data from broader studies with limited inclusion of clear cell histology. This review underscores the need for more specific evidence to refine treatment protocols and balance efficacy with the minimization of treatment-related morbidity. Third, we explored novel therapeutic strategies for the treatment of recurrent diseases. Advances in the understanding of the biology of clear cell carcinomas have identified potential targets in the immune microenvironment, cellular processes, and metabolism. Ongoing clinical trials are investigating these approaches, which hold promise in transforming the treatment landscape and outcomes. In conclusion, this review emphasizes the necessity for international collaboration and the inclusion of diverse patient populations to address the challenges posed by cell carcinomas. By focusing on these controversies, we aim to stimulate further research and support more evidence-based personalized approaches for the management of these rare but challenging cancers.
