Copy number loss of CDKN2A was associated with advanced tumour stage (T3/4: 7/71 vs. T1/2: 0/105, p = 0.001) and loss of BRCA2 was associated with advanced tumour stage (T3/4: 8/71 vs. T1/2: 1/105, p = 0.003), nodal disease (N+: 7/61 vs. N0: 2/115, p = 0.009), extracapsular spread (ECS+: 4/20 vs. ECS-: 5/156, p = 0.011) and NSND status (NSND: 7/59 vs. SD: 2/117, p = 0.007). The gene discussed is CDKN2A; the disease is neoplasm.
