OBJECTIVES The short-term efficacy of virtual-assisted lung mapping (VAL-MAP), a preoperative bronchoscopic multi-spot lung-marking technique, has been confirmed in 2 prospective multicentre studies. The objectives of this study were to analyse the local recurrence and survival of patients enrolled in these studies, long-term. METHODS Of the 663 patients enrolled in the 2 studies, 559 patients’ follow-up data were collected. After excluding those who did not undergo VAL-MAP, whose resection was not for curative intent, who underwent concurrent resection without VAL-MAP, or who eventually underwent lobectomy instead of sublobar resection (i.e. wedge resection or segmentectomy), 422 patients were further analysed. RESULTS Among 264 patients with primary lung cancer, the 5-year local recurrence-free rate was 98.4%, and the 5-year overall survival (OS) rate was 94.5%. Limited to stage IA2 or less (≤2 cm in diameter; n = 238, 90.1%), the 5-year local recurrence-free and OS rates were 98.7% and 94.8%, respectively. Among 102 patients with metastatic lung tumours, the 5-year local recurrence-free rate was 93.8% and the 5-year OS rate was 81.8%. Limited to the most common (colorectal) cancer (n = 53), the 5-year local recurrence-free and OS rates were 94.9% and 82.3%, respectively. CONCLUSIONS VAL-MAP, which is beneficial in localizing small barely palpable pulmonary lesions and determining the appropriate resection lines, was associated with reasonable long-term outcomes.

小肺结节亚肺叶切除的虚拟辅助肺标测，长期结果

目的 虚拟辅助肺标测 (VAL-MAP) 是一种术前支气管镜多点肺标记技术，其短期疗效已在 2 项前瞻性多中心研究中得到证实。本研究的目的是长期分析参加这些研究的患者的局部复发和生存率。方法 2 项研究共纳入 663 例患者，收集 559 例患者的随访资料。在排除未接受 VAL-MAP、切除不是出于治愈目的的患者、未接受 VAL-MAP 的同时切除或最终接受肺叶切除而不是亚肺叶切除（即楔形切除或肺段切除术）的患者后，进一步分析了 422 例患者。 . 结果 264例原发性肺癌患者5年局部无复发率为98.4%，5年总生存率（OS）为94.5%。仅限于 IA2 期或更小（直径≤2 cm；n = 238, 90.1%），5 年局部无复发率和 OS 率分别为 98.7% 和 94.8%。102例转移性肺肿瘤患者5年局部无复发率为93.8%，5年OS率为81.8%。限于最常见的（结直肠）癌症（n = 53），5 年局部无复发率和 OS 率分别为 94.9% 和 82.3%。结论 VAL-MAP 有助于定位几乎无法触及的微小肺部病变并确定适当的切除线，与合理的长期结果相关。主题集合 152, 1542 102例转移性肺肿瘤患者5年局部无复发率为93.8%，5年OS率为81.8%。限于最常见的（结直肠）癌症（n = 53），5 年局部无复发率和 OS 率分别为 94.9% 和 82.3%。结论 VAL-MAP 有助于定位几乎无法触及的微小肺部病变并确定适当的切除线，与合理的长期结果相关。主题集合 152, 1542 102例转移性肺肿瘤患者5年局部无复发率为93.8%，5年OS率为81.8%。限于最常见的（结直肠）癌症（n = 53），5 年局部无复发率和 OS 率分别为 94.9% 和 82.3%。结论 VAL-MAP 有助于定位几乎无法触及的微小肺部病变并确定适当的切除线，与合理的长期结果相关。主题集合 152, 1542 这有利于定位几乎无法触及的小肺部病变并确定适当的切除线，与合理的长期结果相关。主题集合 152, 1542 这有利于定位几乎无法触及的小肺部病变并确定适当的切除线，与合理的长期结果相关。主题集合 152, 1542
