Higher PARP expression was significantly associated with larger tumours (OR = 1.53, 95% CI = 1.00–2.34, p = 0.048), a higher tumour grade (HR = 1.53, 95% CI = 1.00–2.34, p = 0.048), the presence of lymph node metastasis, the presence of distant metastases (OR = 1.53, 95% CI = 1.00–2.34, p = 0.048), a higher TNM stage (HR = 1.53, 95% CI = 1.00–2.34, p = 0.048), and the presence of lymphovascular invasion (Table 3 and Supplementary Figures S7 and S8). The gene discussed is PARP1; the disease is metastatic malignant neoplasm in the lymph nodes.
