Long-read sequencing of ovarian cancer organoid
Two patient-derived organoids were derived from separate ascites fluid collections from a patient diagnosed with high-grade mullerian carcinoma, that could not be confidently subclassified based on the limited specimen. Long-read sequencing whole genome sequencing (WGS) was performed on the organoids, OC104 and OC109, using the Oxford Nanopore Technologies PromethION24 with V14 ligation kit. Information from genomic findings and further pathology on organoids suggests refining the diagnosis to mucinous ovarian carcinoma.
