摘要

上下文。在解剖病理学实践中,低分化或未分化肿瘤的检查仍然是一个重要且具有挑战性的实体。特别是在小活检和材料有限的情况下,这些病例需要一个平衡的方法,考虑患者的临床和放射学表现,肿瘤形态的基本评估,合理广泛的免疫组织化学小组,以及为预后和治疗研究而努力保存组织。-:说明一些新的和新兴的免疫组织化学标记物在未分化或低分化形态肿瘤的评估中,重点是在有限的组织样本中进行检查,以提高对这些具有挑战性的肿瘤的病理检查所涉及的问题的认识。数据源。-:对可应用于细胞学标本的新的辅助研究进行了文献综述。-:对患者病史的了解以及与患者临床团队的沟通对于制定鉴别诊断至关重要,可以适当地限制基于形态学的鉴别诊断,特别是在小样本中。这些信息与肿瘤形态分类(如上皮样、纺锤状、神经内分泌、基底样/双相、混合)相结合,为选择初始免疫组化面板提供了一种合乎逻辑的方法。幸运的是,随着突破性的分子研究的发展,免疫组织化学正在迅速发展,以开发新的更好的标记物,进一步分类这些困难的肿瘤,超出了我们传统上能够做到的。

Current Approach to Undifferentiated Neoplasms, With Focus on New Developments and Novel Immunohistochemical Stains.

Context.—: Workup of the poorly differentiated or undifferentiated tumor remains a significant and challenging entity in the practice of anatomic pathology. Particularly in the setting of small biopsies and limited material, these cases demand a balanced approach that considers the patient's clinical and radiologic presentation, a basic assessment of tumor morphology, a reasonably broad immunohistochemical panel, and diligent preservation of tissue for prognostic and therapeutic studies.

Objective.—: To illustrate some of the new and emerging immunohistochemical markers in the evaluation of tumors with undifferentiated or poorly differentiated morphology, with a focus on the workup in limited tissue samples to raise awareness of the issues involved with the pathologic workup in these challenging tumors.

Data sources.—: A literature review of new ancillary studies that can be applied to cytologic specimens was performed.

Conclusions.—: Knowledge of the patient's history and communication with the patient's clinical team is essential in formulating a differential diagnosis that can appropriately limit the differential diagnosis based on morphology, especially in small specimens. This information, in conjunction with classifying the tumor morphology (eg, epithelioid, spindled, neuroendocrine, basaloid/biphasic, mixed) gives a logical approach to choosing an initial immunohistochemical panel. Fortunately, immunohistochemistry is evolving quickly in the wake of groundbreaking molecular studies to develop new and better markers to further classify these difficult tumors beyond where we traditionally have been able to go.
