项目摘要

SUMMARY Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death in the United States for which surgery remains a critical treatment option. The appropriate extent of resection for NSCLC is highly dependent on intra-operative decision-making. Specifically, the diagnosis of NSCLC is often determined intra-operatively by a limited resection of a suspicious pulmonary nodule, and intraoperative diagnosis is required before proceeding to a larger, cancer-specific resection during the same procedure. Further, intraoperative evaluation of resection margins is required in NSCLC surgeries to assure complete cancer removal before leaving the operating room (OR). Thus, the ability to accurately diagnose NSCLC and determine surgical margins in the OR is critical in the care for patients with NSCLC. However, the current technology used for intraoperative evaluation of NSCLC diagnosis and margins is frozen section analysis, a century-old technique that is labor-intensive and prone to error. Frozen section analysis also extends operative time, subjecting patients to increased risks of surgical complications. New technologies that can provide surgeons with the ability to rapidly and accurately diagnose NSCLC in the OR and evaluate surgical margins with high accuracy are critically needed to improve surgical care and outcomes for patients. We have reported the development of an innovative technology, the MasSpec Pen (MSPen), for rapid and non-destructive diagnosis of cancer tissues. The MSPen deploys a single droplet of water to gently extract molecules from tissues, which are then analyzed by mass spectrometry (MS) and statistical classifiers to provide diagnosis in seconds. We have demonstrated that the MSPen can accurately diagnose NSCLC using banked tissues with 97% accuracy. We have also shown that the MSPen system can be translated to the OR for use by surgeons for rapid in vivo and ex vivo tissue analysis. Through a collaborative partnership between academic scientists and surgeons at Baylor College of Medicine and the R&D team at MSPen Technologies Inc., we now propose to refine and validate the MSPen for intraoperative diagnosis and surgical margin evaluation in NSCLC. Our objective is to optimize and translate new MSPen technology for NSCLC detection, test its functionality, and validate its performance in the OR setting, thus delivering a potentially improved platform for intraoperative lung tissue analysis to surgeons - the end users. Our specific aims are: Aim 1. Optimize the MSPen Technology for intraoperative use in NSCLC operations. We will develop a next-gen MSPen platform for use in open and robotic NSCLC surgeries; Aim 2. Validate the MSPen for NSCLC diagnosis. We will conduct a prospective observational study allowing thoracic surgeons to validate the technology for NSCLC diagnosis in the OR; Aim 3. Validate the MSPen for intraoperative surgical margin evaluation in NSCLC. We will validate the MSPen technology for surgical margin evaluation in vivo and ex vivo, including the most representative tissue margins that are currently disregarded in clinical care. Our propose has the potential to offer transformative benefits to surgeons in advancing the surgical standard of care for patients with lung cancer.
总结 非小细胞肺癌(NSCLC)是美国癌症相关死亡的主要原因, 手术仍然是一个关键的治疗选择。NSCLC的适当切除范围高度依赖于 关于内部决策。具体而言,NSCLC的诊断通常在术中确定 通过可疑肺结节的有限切除术,术前需要术中诊断, 在同一手术中进行更大的癌症特异性切除。此外,术中评价 在NSCLC手术中,要求切除边缘的边缘,以确保在离开手术室之前完全切除癌症。 手术室(OR)因此,准确诊断NSCLC和确定手术切缘的能力 在NSCLC患者的护理中至关重要。然而,目前用于术中评估的技术 冷冻切片分析是NSCLC诊断和切缘的一项重要技术,这是一项具有百年历史的技术, 容易出错冷冻切片分析也延长了手术时间,使患者面临更大的风险, 手术并发症新技术可以为外科医生提供快速准确地 在手术室中诊断NSCLC并以高准确度评估手术切缘, 手术护理和患者的结果。我们已经报道了一种创新技术的发展, MasSpec Pen(MSPen),用于快速和非破坏性诊断癌症组织。MSPen部署单个 水滴轻轻地从组织中提取分子,然后通过质谱法(MS)进行分析 和统计分类器,在几秒钟内提供诊断。我们已经证明,MSPen可以准确地 使用库存组织诊断NSCLC的准确率为97%。我们还表明,MSPen系统可以 被翻译到OR以供外科医生用于快速体内和离体组织分析。通过一个合作 贝勒医学院的学术科学家和外科医生与 MSPen Technologies Inc.,我们现在建议改进和验证MSPen用于术中诊断, NSCLC手术切缘评价我们的目标是优化和转化新的MSPen技术, NSCLC检测,测试其功能,并验证其在OR环境中的性能,从而提供潜在的 为外科医生(最终用户)提供改进的术中肺组织分析平台。我们的具体目标是:目标 1.优化MSPen技术在NSCLC手术中的术中使用。我们将开发下一代 用于开放式和机器人NSCLC手术的MSPen平台;目的2。将MSPen用于NSCLC诊断。 我们将进行一项前瞻性观察研究,使胸外科医生能够验证该技术, 手术室中的NSCLC诊断;目标3。使用MSPen进行NSCLC术中手术切缘评价。 我们将在体内和体外验证MSPen技术用于手术切缘评估,包括最 目前在临床护理中被忽视的代表性组织边缘。我们的提议有可能 为外科医生提高肺癌患者的外科护理标准提供变革性益处。
