Despite recent notable treatment advancements, ovarian cancer survival rates remain poor, with about half of women surviving five years after diagnosis. Uncovering novel prognostic factors is critical to better understand and reduce mortality from this deadly disease. While genome-wide association studies have identified numerous loci associated with risk of epithelial ovarian cancer, the investigation of genetic factors associated with outcomes among women with ovarian cancer has been limited due to several challenges summarized in the present commentary. Using data from the Ovarian Cancer Association Consortium, Quinn and colleagues conducted a genome-wide association study of patients with ovarian cancer receiving debulking surgery and standard chemotherapy as first-line treatment, revealing a locus at 12q24.33 associated with progression-free survival. Experimental evidence suggests that ULK1, a gene coding for a serine/threonine kinase implicated in autophagy, is the target of the association. We discuss the novelty of these findings, unanswered questions, and next steps for the road ahead in translating the work of Quinn and colleagues into clinical practice.
