该协议描述了一种促进从根治性前列腺切除术标本收集样本的方法。目标是根据解剖病理学标准对标本中的组织样本进行映射、表征和微观-宏观解剖,然后再将它们储存在生物样本库中。

我们的研究重点是提高获得高质量前列腺癌组织样本的方法。它解决了前列腺癌研究中肿瘤病灶的遗传瘤内异质性、多焦点性和精确分子表征等挑战。生物样本库是一种技术驱动实践,它系统地收集、处理和储存生物样本。

整合这些技术可以从表征良好的前列腺癌样本中生成广泛的数据集,促进合作,提高研究水平,提高可靠性,并帮助开发针对前列腺癌患者的个性化医疗和策略。病理学面临着一些实验变化,包括肿瘤内异质性、组织病理学标准化、分子数据整合、实验室密集型过程、用于自动化电子图像分析的气候定量分析。解决这些问题需要持续的技术进步、标准化举措、跨学科合作以及改进的实验和计算方法。

该协议可高效、准确地处理肿瘤取样。集成成像和活检数据,实现精确定位。提供实时组织病理学见解,降低成本和时间,提高样本质量,并最大限度地减少所有缺血时间。

这解决了前列腺癌组织病理学研究中的关键挑战。我们的方案可以通过提高对肿瘤组织病理学数据的理解、增强生物样本库、促进合作和实现个性化医疗来改变前列腺癌研究。纵向生物样本库揭示了时间变化,阐明了疾病进展和治疗反应,交互了多数据,揭示了前列腺癌的分子神经和新型生物标志物。
