概括

p16免疫染预测前列腺癌中的生化复发. 结合格里森评分和外科边缘,p16表达有助于评估pT2-pT3瘤复发风险.

科学领域:

在瘤学瘤学.
病理学病理学病理学
生物化学生物化学

背景情况:

前列腺癌的分期 (pT2-pT3) 对于治疗决策至关重要.
生物化学复发是治疗疗效的关键指标.
了解复发的预测因素对于患者管理至关重要.

研究的目的:

评估p16免疫组织化学表达对生化复发率的影响.
为了将p16表达与前列腺癌中确定的预后因素相关联.

主要方法:

对488个急性前列腺切除样本 (前列腺腺癌pT2-pT3) 的分析.
对p16表达进行了免疫组织化学检查.
统计分析包括千平方,费舍尔的精确测试和后勤回归.

主要成果:

超过94%的病例显示p16阳性.
生物化学复发与高的PSA,积极的边缘,pT3阶段,节点参与,更高的格里森得分和更低的p16阳性/基因组分相关.
多变量分析确定格里森得分>3+4,积极的外科边缘,和p16基因组值≤3作为复发的独立预测因素.

结论:

在pT2-pT3前列腺癌中,p16免疫染是生物化学复发的重要预测因子.
除了格里森评分和外科手术边缘,p16表达改善了风险分层.
这些发现可以有助于改进治疗策略和患者的随访.

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
