Description

一种骨髓涂片数字化的流程方法 技术领域
本发明属于计算机医学骨髓涂片检查领域,具体涉及一种骨髓涂片数字化的流程方法。
背景技术
骨髓细胞形态学镜检是血液学中关键诊断手段之一,常用于诊断多种病症,包括白血病、多发性骨髓瘤、淋巴瘤、贫血和全血细胞减少。根据世界卫生组织发布的《骨髓恶性肿瘤诊断指南》,在诊断时需要进行详细、精确的显微镜人工检查。正常骨髓含有发育阶段的所有分化细胞,从早期前体干细胞到功能成熟细胞,包括作为大多数血细胞前体的造血干细胞以及被认为是骨髓的守门员细胞的间充质干细胞和内皮干细胞。这些细胞的形态学特征取决于涂片、染色和图像采集过程。对于某些疾病,能够通过一些已发现的更加特异的免疫或分子标记对非典型细胞计数进行精确评估,然而这些标记物不适用于所有疾病。目前人工镜检仍然是主要或唯一的诊断和治疗疗效监测的方法。其主要缺陷在于:
(1)工作效率较低。传统的镜检均需血液学家/病理学家人工在显微镜下观察标本做出诊断。从拿到染色完成的标本涂片开始,需要经过以下流程: 1、阅读检查申请单,确认患者信息和临床内容及要求检查项。 2、肉眼观察涂片标本,选择染色和推片相对满意的涂片。 3、低倍镜观察涂片,计数全片巨核细胞数量,评估细胞增生情况,观察有无稀释或异常细胞。4、油镜观察涂片,选择骨髓小粒周围细胞分布均匀的区域,采用弓字形或城垛形移动方式,计数分类200个有核细胞,25个巨核细胞, 边观察分类边将结果记录在纸质的有核细胞分类表或细胞计数器中。 5、根据镜检结果及临床信息和其他检查结果对本次标本做出形态学诊断,推断或解释。 6、将分类结果和检查结果录入报告系统并打印纸质报告。 当前,骨髓检查的报告周期还是偏长,一般在3个工作日左右, 有的医院甚至一周发出报告,过长的报告周期不适宜于现代医学的反应性。长时间的人工显微镜观察,也容易造成形态学检验人员眼部和颈椎的疲劳。
(2)需较强的工作经验。形态学是经典的强经验性医学。没有长期的工作经验积累和技术熟练程度提高难以做出高质量的检查报告。专业的形态学技能是与持续不断的学习、实践、再学习相伴随的,同时需要与基础医学和临床医学交融在一起。形态学的把握及其意义评判是一个复杂而繁琐的过程,其中还包括了时常会遇到的一些灵活性和特殊性,即使有时相同或类似的细胞数量和形态,在临床和其他结果不一样下也会有结果的差异。医学教材中描述的都是基础的,十分典型的细胞形态,往往侧重于教学的意义而缺乏普遍性,在实际操作中,不同的患者,不同厚薄的涂片,不同的区域和染色差异的标本中,细胞大小和形状变化是较大的。 因此,合格的血液学家/病理学家培养也是一个漫长而枯燥的过程,再加上一些其他因素的影响,也导致很多医院出现了形态学检验 人员缺失、断层的现象。
(3)镜检标准不统一。当前,我国进行的传统骨髓细胞形态学诊断主要依靠骨髓涂片人工镜检。血片虽一直提倡,但现状是经常被轻视或疏忽。其他检查方式也往往分属于不同科室或部门,几乎都是单项目而忽视了这些检查方法之间的内在联系。一些原本薄弱的血细胞检验部门,在血细胞分析仪自动化的特定环境影响下,放松了对血细胞形态学的检验诊断,影响了血液形态学的发展和整体诊断水平的提升。2008年ICSH 报告的骨髓标本和报告标准化指南中,强调完整的形态学诊断常常需要骨髓涂片与血片(包括细胞化学染色)等综合检查。通过综合检查可以合理的将几种相关检查方法加以互补和整合,推动血液形态学的整体发展。
