WebAug 23, 2024 · When compared with the UV-FISH assay, polysomy by PB-FISH was found to have a significantly higher sensitivity for pancreaticobiliary cancer detection than polysomy by UV-FISH or routine cytology (65% vs 46%; P < 0.001) . There have been no studies determining the utility of PB-FISH assays for determining patient outcomes.
WebMar 6, 2014 · The term “polysomy” (often defined as a cell demonstrating ≥ 3 signals in ≥ 2 of the 4 probes) can carry a broad interpretation.
