Abstract

Introduction:  We aimed to investigate the accuracy of clinical staging without the routine use of positron emission tomography/computed tomography (PET/CT) in patients with cIA1 and cIA2 non-small-cell lung cancer (NSCLC) scheduled for segmentectomy.

Methods:  A total of 305 consecutive segmentectomies were retrospectively analyzed. Overall survival was calculated using the Kaplan-Meier method. Logistic regression was performed to investigate factors independently associated with pathologic upstaging.

Results:  The Union for International Cancer Control (UICC) upstaging was found in 86 patients (28%). Upstaged patients had longer operative times (146 ± 46 vs. 131 ± 44 minutes, p = 0.009), a higher number of lymph node resection (17 ± 10 vs. 13 ± 8, p = 0.001), and a higher rate of L1 involvement (34 vs. 16%, p < 0.001) than nonupstaged patients. N1 was found in 10 patients (3%) and N2 in 13 patients (4%). Nodal positive patients had longer operation times (154 ± 50 vs. 133 ± 44 minutes, p = 0.031) and higher rates of R1 (9 vs. 1%, p = 0.006) and L1 (39 vs. 20%, p < 0.026) than patients without nodal involvement. The 3- and 5-year overall survival rates for nonupstaged and upstaged patients were 85 and 67% and 67 and 54%, respectively (p = 0.040). In logistic regression, L1 involvement (odds ratio [OR]: 2.394, p = 0.005) and the number of dissected lymph nodes (OR: 1.037, p = 0.016) were independently associated with upstaging. Patients who received PET as part of clinical staging did not have a significantly lower nodal upstaging.

Conclusion:  Selective use of PET/CT based on the results of CT may be a viable option for patients with proven or suspected NSCLC up to 2 cm in size.

在没有常规 PET 的情况下,对分段切除术候选者的早期肺癌进行分期。
简介方法:对305例连续分段切除术进行了回顾性分析。采用 Kaplan-Meier 法计算总生存率。采用逻辑回归法研究与病理分期相关的独立因素:结果:86例患者(28%)发现了UICC上分期。与未分期患者相比,上分期患者的手术时间更长(146±46分钟 vs. 131±44分钟,p= 0.009),切除的淋巴结数量更多(17±10 vs. 13±8,p= 0.001),L1受累率更高(34% vs. 16%,p< 0.001)。10名患者(3%)发现N1,13名患者(4%)发现N2。与无结节受累的患者相比,结节阳性患者的手术时间更长(154 ± 50 分钟对 133 ± 44 分钟,p= 0.031),R1(9% 对 1%,p= 0.006)和 L1(39% 对 20%,p< 0.026)率更高。分期和未分期患者的3年和5年总生存率分别为67%和54%,以及85%和67%(P=0.040)。在逻辑回归中,L1受累(OR 2.394,p= 0.005)和切除淋巴结的数量(OR 1.037,p= 0.016)与上分期独立相关。接受 PET 作为临床分期一部分的患者的结节向上分期并没有明显降低:结论:根据计算机断层扫描结果有选择性地使用 PET/CT 可能是 2 厘米以下已证实或疑似 NSCLC 患者的可行选择。
