HLRCC related tumours lack the enzyme fumarate hydratase (FH) and act very differently at the molecular level compared to other (more common) kidney cancers (RCC). Understanding the special traits of these cancers is critical for accurate diagnosis.
This newly published review article provides details of a study where researchers found different molecular subgroups within FH‑deficient RCC, each with its own potential vulnerabilities that could provide new drug targets.
Armed with this new understanding, the researchers suggest it may be possible to tailor treatments to individual molecular signatures of FH-deficient tumours—which might improve outcomes for patients with HLRCC.
New research has provided a comprehensive molecular understanding of fumarate hydratase-deficient renal cell carcinoma, showing distinct molecular divergence from other renal tumour subtypes. These molecular findings have implications for precision oncology for patients with this rare disease.
