Abstract:
Gynecologic carcinosarcomas, specifically of endometrial and ovarian origin, are aggressive and rare tumors. Treatment data are limited and are often extrapolated from other histologies and smaller retrospective studies. While the optimal therapy approach remains contentious, treatment is often multimodal and may include surgery, chemotherapy, radiation, or a combination of multiple strategies. However, despite aggressive treatment, these tumors fare worse than carcinomas of the same anatomic sites irrespective of their stage. Recent studies have described in-depth molecular characterizations of gynecologic carcinosarcomas. Although many molecular features mirror those seen in other uterine and ovarian epithelial tumors, the high prevalence of epithelial-mesenchymal transition is more unique. Recently, molecular descriptions have expanded to begin to characterize the tumor immune microenvironment. While the importance of the immune microenvironment has been well-established for other tumor types, it has been less systematically explored in gynecologic carcinosarcomas. Furthermore, the use of immunotherapy in patients with gynecologic carcinosarcomas has not been extensively evaluated. In this review, we summarize the available data surrounding gynecologic carcinosarcomas, with a focus on the immune microenvironment. We end with a discussion of potential immunotherapy uses and future directions for the field.
Insights
Gynecologic carcinosarcomas are rare, aggressive tumors. This review focuses on their immune microenvironment and the potential of immunotherapy for improved treatment outcomes.
Area of Science:
- Gynecologic Oncology
- Cancer Immunology
- Translational Oncology
Background:
- Gynecologic carcinosarcomas (endometrial, ovarian) are rare, aggressive neoplasms with poor prognoses.
- Current treatment strategies are often multimodal but lack robust evidence, with outcomes inferior to carcinomas.
- Limited data exist on the tumor immune microenvironment and immunotherapy efficacy in these cancers.
Purpose of the Study:
- To review current knowledge on gynecologic carcinosarcomas.
- To focus on the tumor immune microenvironment in these rare cancers.
- To explore the potential of immunotherapy and future research directions.
Main Methods:
- Comprehensive literature review of gynecologic carcinosarcomas.
- Analysis of molecular characteristics, including epithelial-mesenchymal transition.
- Examination of the tumor immune microenvironment and immunotherapy data.
Main Results:
- Gynecologic carcinosarcomas exhibit unique molecular features, notably high epithelial-mesenchymal transition rates.
- The tumor immune microenvironment is increasingly recognized but underexplored in these tumors.
- Immunotherapy efficacy remains largely unevaluated in clinical practice.
Conclusions:
- Understanding the immune microenvironment is crucial for advancing gynecologic carcinosarcoma treatment.
- Immunotherapy holds promise, but further research is essential to establish its role.
- Future studies should focus on immune profiling and clinical trials of immunotherapy.
