Hypersensitive Cancer hotspot sequencing panel in patients with two or more subtypes of endometriosis

This study investigated genomic heterogeneity across anatomically distinct endometriosis lesions by sequencing 27 patients who had two or more subtypes, using a hypersensitive cancer hotspot panel on macrodissected tissue, with droplet digital PCR validation planned for detected mutations. Mutations in KRAS, NRAS, CTNNB1, EGFR, ERBB2, and PIK3CA were found in 12 of 24 cases; PTEN loss occurred in three cases, while ARID1A loss was not observed. Identical alterations were detected across more than one lesion/type in three cases, suggesting clonal relationships, but the authors note that some lesions were too small for panel sampling, so clonality validation is pending. This paper is centrally about endometriosis — it analyzes cancer-driver hotspot mutations and PTEN/ARID1A surrogate markers across multiple endometriosis subtypes and lesion locations to assess clonal and malignant potential heterogeneity.
