The HLRCC Foundation (Formerly HLRCC Family Alliance) supports those individuals, and their families, who have been diagnosed with Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) or Fumarate hydratase–deficient (FH-deficient) renal cell carcinoma (RCC) or Fumarase Deficiency. HLRCC is characterized by uterine fibroids, leiomyomas of the skin and potentially a very aggressive kidney cancer

A new study by Zhang et al., tested a novel treatment for HLRCC using a combination of two drugs, a programmed cell death 1 protein (PD-1) inhibitor (sintilimab) and a vascular endothelial growth factor receptor–targeted tyrosine kinase inhibitor (VEGFR-TKI; axitinib). This treatment worked well for over half of patients keeping the cancer under control for a median of nearly 20 months. Side effects were mostly mild and manageable, suggesting this combination is a promising new option.
