Roche(SIX:RO,ROG;OTCQX:RHHBY)今日宣布,其高灵敏度原位杂交(ISH)检测——VENTANA® Kappa和Lambda双重ISH mRNA探针组合——已获得美国食品药品监督管理局(FDA)的510(k)批准。4 该检测旨在帮助病理学家区分B细胞恶性肿瘤与感染引起的正常反应性增生,从而加快治疗进程。4 此公告发布于该检测于2024年6月获得CE标志批准之后。
B细胞淋巴瘤是一种通常在淋巴系统中发生的癌症。它约占非霍奇金淋巴瘤(NHL)病例的85%。3 NHL是美国最常见的癌症类型之一,约占所有癌症病例的4%5,每年导致超过80,000人死亡。5 在NHL的早期阶段,患者可能会出现淋巴结肿大、发烧、疲劳、食欲不振或皮疹等症状。
“准确区分淋巴瘤和感染对于确保诊断的准确性和及时性至关重要,尤其是在症状可能相似的情况下,”罗氏诊断病理实验室负责人Jill German表示。“有了这项新检测,临床医生可以在诊断上更有信心,同时该检测减少了对多个样本和耗时随访检测的需求,让患者能更快获得确定性诊断,并更快地获得正确治疗。”
新型VENTANA Kappa和Lambda双重ISH mRNA探针组合通过提高灵敏度,能够在单个组织切片上评估60多种B细胞淋巴瘤亚型和浆细胞肿瘤。该检测可评估小活检样本和福尔马林固定组织,减少了对新鲜组织样本的需求,而新鲜组织样本可能无法获得,尤其是在最初未怀疑淋巴瘤的情况下。这些检测特性可以保存组织,可能减少额外的患者活检次数,并使病理学家的解读更快、更容易,从而帮助患者更快地获得诊断和治疗。
这项首创的检测是罗氏行业领先的血液病理学产品组合的重要补充,该产品组合包含65种以上的生物标志物。
关于VENTANA Kappa和Lambda双重ISH mRNA探针组合
VENTANA Kappa和Lambda双重ISH mRNA探针组合检测是一种定性检测,通过原位杂交(ISH)用于检测福尔马林固定石蜡包埋(FFPE)的人类血液淋巴组织标本中kappa和lambda免疫球蛋白轻链的表达。
The assay is intended as an aid in the diagnosis of mature B-cell lymphomas and plasma cell neoplasms. The VENTANA Kappa and Lambda Dual ISH mRNA Probe Cocktail is indicated for use when a biopsy of lymph node or bone marrow (core biopsy and clot section) indicates inconclusive results. It enables the assessment of both markers in the context of one another on a single slide as an aid in differentiating between a reactive process or B-cell lymphoma and plasma cell neoplasms.
This is not a standalone test, and results should be evaluated by a qualified pathologist within the context of the patient’s clinical history and other diagnostic tests. This product is intended for in vitro diagnostic (IVD) use.4
