Ovarian cancer: targeting the untargetable

Area of Science:

• Oncology
• Genomics
• Translational Research

Background:

• Epithelial ovarian cancer (EOC) is characterized by genomic instability.
• High-grade serous carcinomas often lack actionable driver mutations, complicating targeted therapy approaches.
• The premise of universally targetable tumors faces controversy in EOC management.

Purpose of the Study:

• To advocate for a nuanced interpretation of genomic data in ovarian cancer.
• To emphasize the importance of examining extensive genomic alterations beyond simple mutations.
• To highlight the role of stromal factors in EOC pathogenesis and treatment.

Main Methods:

• Review and interpretation of existing genomic data in epithelial ovarian cancer.
• Consideration of DNA alterations and their impact on gene function.
• Inclusion of the tumor microenvironment, specifically the stroma, in analysis.

Main Results:

• Genomic analysis reveals significant instability in EOC, particularly high-grade serous carcinomas.
• Ovarian tumors frequently lack straightforward, actionable mutations comparable to HER2 in other cancers.
• A comprehensive approach integrating tumor genomics and stromal interactions is necessary.

Conclusions:

• Precision medicine in ovarian cancer requires a deeper look at genomic data, including extensive alterations and stromal contributions.
• Translational research is essential for improving drug discovery and treatment strategies for EOC.
• Rethinking the interpretation of genomic data is key to advancing ovarian cancer care.
