Adequate tumor yield in core-needle biopsy (CNB) specimens is essential in lung cancer for accurate histological diagnosis, molecular testing for therapeutic decision-making, and tumor biobanking for research. Insufficient tumor sampling in CNB is common, primarily due to inadvertent sampling of tumor-associated fibrosis or atelectatic lung, leading to repeat procedures and delayed diagnosis. Currently, there is no method for rapid, non-destructive intraprocedural assessment of CNBs. Polarization-sensitive optical coherence tomography (PS-OCT) is a high-resolution, volumetric imaging technique that has the potential to meet this clinical need. PS-OCT detects endogenous tissue properties, including birefringence from collagen, and degree of polarization uniformity (DOPU) indicative of tissue depolarization. Here, PS-OCT birefringence and DOPU measurements were used to quantify the amount of tumor, fibrosis, and normal lung parenchyma in 42 fresh, intact lung CNB specimens. PS-OCT results were compared to and validated against matched histology in a blinded assessment. Linear regression analysis showed strong correlations between PS-OCT and matched histology for quantification of tumors, fibrosis, and normal lung parenchyma in CNBs. PS-OCT distinguished CNBs with low tumor content from those with higher tumor content with high sensitivity and specificity. This study demonstrates the potential of PS-OCT as a method for rapid, non-destructive, label-free intra-procedural tumor yield assessment.

使用偏振敏感光学相干断层扫描在新鲜肺芯针活检中快速无损体积肿瘤产量评估

核心针活检 (CNB) 标本中足够的肿瘤产量对于肺癌的准确组织学诊断、治疗决策的分子检测和研究的肿瘤生物库至关重要。CNB 中的肿瘤取样不足很常见,主要是由于无意中对肿瘤相关纤维化或肺不张进行取样,导致重复手术和延误诊断。目前,还没有对 CNB 进行快速、无损的程序内评估的方法。偏振敏感光学相干断层扫描 (PS-OCT) 是一种高分辨率的体积成像技术,有可能满足这种临床需求。PS-OCT 检测内源性组织特性,包括胶原蛋白的双折射和指示组织去极化的偏振均匀度 (DOPU)。这里,PS-OCT 双折射和 DOPU 测量用于量化 42 个新鲜、完整的肺 CNB 标本中的肿瘤、纤维化和正常肺实质的数量。在盲法评估中,将 PS-OCT 结果与匹配的组织学进行比较和验证。线性回归分析显示 PS-OCT 与匹配的组织学在 CNB 中量化肿瘤、纤维化和正常肺实质之间存在强相关性。PS-OCT 以高灵敏度和特异性区分肿瘤含量低的 CNB 与肿瘤含量高的 CNB。这项研究证明了 PS-OCT 作为一种快速、非破坏性、无标记的术中肿瘤产量评估方法的潜力。在盲法评估中,将 PS-OCT 结果与匹配的组织学进行比较和验证。线性回归分析显示 PS-OCT 与匹配的组织学在 CNB 中量化肿瘤、纤维化和正常肺实质之间存在强相关性。PS-OCT 以高灵敏度和特异性区分肿瘤含量低的 CNB 与肿瘤含量高的 CNB。这项研究证明了 PS-OCT 作为一种快速、非破坏性、无标记的术中肿瘤产量评估方法的潜力。在盲法评估中,将 PS-OCT 结果与匹配的组织学进行比较和验证。线性回归分析显示 PS-OCT 与匹配的组织学在 CNB 中量化肿瘤、纤维化和正常肺实质之间存在强相关性。PS-OCT 以高灵敏度和特异性区分肿瘤含量低的 CNB 与肿瘤含量高的 CNB。这项研究证明了 PS-OCT 作为一种快速、非破坏性、无标记的术中肿瘤产量评估方法的潜力。PS-OCT 以高灵敏度和特异性区分肿瘤含量低的 CNB 与肿瘤含量高的 CNB。这项研究证明了 PS-OCT 作为一种快速、非破坏性、无标记的术中肿瘤产量评估方法的潜力。PS-OCT 以高灵敏度和特异性区分肿瘤含量低的 CNB 与肿瘤含量高的 CNB。这项研究证明了 PS-OCT 作为一种快速、非破坏性、无标记的术中肿瘤产量评估方法的潜力。
