Lung cancer is associated with high mortality. It can present as one or more pulmonary nodules identified on computed tomography (CT) chest scans. The National Lung Screening Trial has shown that the use of low-dose CT chest screening can reduce deaths due to lung cancer. High adherence to appropriate follow-up of positive results, including imaging or interventional approaches, is an important aspect of pulmonary nodule management. Our study is one of the first to evaluate the current practice in managing pulmonary nodules and to explore potential causes for nonadherence to follow-up. This is a retrospective analysis at St. Paul's Hospital, a tertiary healthcare center in Vancouver, British Columbia, Canada. We first identified CT chest scans between January 1 to June 30, 2014, that demonstrated one or more pulmonary nodules equal to or greater than 6 mm in diameter. We then looked for evidence of interventional (surgical resection or biopsy, or bronchoscopy for transbronchial biopsy and cytology) and radiological follow-up of the pulmonary nodule by searching on the province-wide CareConnect eHealth Viewer patient database. A total of 1614 CT reports were analyzed and 139 (8.6%) had a positive finding. Out of the 97 patients who received follow-up, 54.6% ( = 53) was referred for a repeat CT chest scan and 36.1% ( = 35) and 9.3% ( = 9) were referred for interventional biopsy and surgical resection, respectively. In our study, 30.2% ( = 42) of the patients with pulmonary nodules were nonadherent to follow-up. Despite the radiologist's recommendation for follow-up within a certain time interval, only 36% had repeat imaging in a timely manner. Our findings reflect the current practice in the management of pulmonary nodules and suggest that there is a need for improvement at our academic center. Adherence to follow-up is important for the potentially near-future implementation of lung cancer screening.
肺癌死亡率高。它可以表现为在计算机断层扫描(CT)胸部扫描上发现一个或多个肺结节。国家肺癌筛查试验表明,使用低剂量 CT 胸部筛查可以降低肺癌死亡率。高度遵守对阳性结果的适当随访,包括影像学或介入方法,是肺结节管理的一个重要方面。我们的研究是评估管理肺结节的当前实践并探讨不遵守随访的潜在原因的首批研究之一。这是加拿大不列颠哥伦比亚省温哥华圣保罗医院的一项回顾性分析。我们首先确定了 2014 年 1 月 1 日至 6 月 30 日期间的 CT 胸部扫描,这些扫描显示一个或多个直径等于或大于 6 毫米的肺结节。然后,我们通过在全省范围内的 CareConnect eHealth Viewer 患者数据库中搜索,寻找肺结节的介入性(手术切除或活检,或经支气管镜活检和细胞学)和影像学随访的证据。总共分析了 1614 份 CT 报告,其中 139 份(8.6%)有阳性发现。在接受随访的 97 名患者中,54.6%(53 名)被转介进行重复 CT 胸部扫描,36.1%(35 名)和 9.3%(9 名)分别被转介进行介入性活检和手术切除。在我们的研究中,30.2%(42 名)的肺结节患者不遵守随访。尽管放射科医生建议在一定时间间隔内进行随访,但只有 36%的患者及时进行了重复成像。我们的研究结果反映了目前肺结节管理的实践情况,并表明我们的学术中心需要改进。遵守随访对于潜在的近未来肺癌筛查的实施非常重要。
