Significant associations were noticed between BCL2 and tumor differentiation (p = 0.036), BAD and tumor localization (p = 0.011), p53 and the number of infiltrated lymph nodes (p = 0.024), BID and maximal tumor diameter and lymphovascular invasion (p = 0.002 and p = 0.049, respectively), MDM2 and maximal tumor diameter (p = 0.015), and Ki-67 and mucinous adenocarcinomas (p = 0.016). The gene discussed is BCL2; the disease is neoplasm.
