Patients were eligible if they were confirmed to have NSCLC, underwent lobectomy, had complete follow-up data, and were not diagnosed with any other malignancies. The propensity score matching (PSM) method was employed to ensure baseline characteristic balance. Two groups of patients matched with the GGO group at baseline were stratified based on overall tumor size (group matched by overall size) and solid component size (group matched by solid component size), respectively. Overall survival (OS) and recurrence-free survival (RFS) were analyzed using the Cox proportional model and Kaplan-Meier method. Follow-up was conducted regularly to assess these outcomes. The T-staging applied was based on the solid component size according to the 8th edition IASLC staging guidelines.</p><p><strong>Results: </strong>A total of 4,472 NSCLC patients who underwent lobectomy were included in the study (including 4,083 cases of solid lesions and 389 cases of subsolid lesions). The median follow-up time was 75.4 months. Patients in the GGO group had significantly better OS and RFS than those in the solid group [OS: hazard ratio (HR) =0.55, 95% confidence interval (CI): 0.40-0.73, P<0.001; RFS: HR =0.53, 95% CI: 0.42-0.67, P<0.001]. Comparing patients' PSM by overall size, the GGO group still had better OS and RFS (OS: HR =0.60, 95% CI: 0.43-0.85, P=0.004; RFS: HR =0.59, 95% CI: 0.44-0.79, P<0.001). After PSM by solid component size, no significant difference was detected between the GGO group and the group matched by solid component size on OS and RFS (OS: HR =0.89, 95% CI: 0.61-1.28, P=0.52; RFS: HR =0.92, 95% CI: 0.67-1.26, P=0.61). In subgroup analysis, after PSM by solid component size, the results showed no difference in OS and RFS between the restaged patients (c-T1 and c-T2) and the corresponding patients in the solid group (for OS, HR =1.06, 95% CI: 0.61-1.83, P=0.83; HR =1.11, 95% CI: 0.60-2.07, P=0.73, respectively; and RFS, HR =1.17, 95% CI: 0.75-1.82, P=0.49; HR =0.80, 95% CI: 0.48-1.34, P=0.39, respectively).</p><p><strong>Conclusions: </strong>The T stage classification strategy proposed by ISALC remains applicable in patients with GGOs larger than 2 cm.</p>","PeriodicalId":23271,"journal":{"name":"Translational lung cancer research","volume":"13 12","pages":"3526-3537"},"PeriodicalIF":4.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11736582/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143012339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its role in the era of chemoimmunotherapy remains underexplored. In the current era of immunotherapy, this study evaluated the efficacy and safety of consolidative TRT (cTRT) in patients with extensive-stage SCLC (ES-SCLC) and assessed its impact on OS. Additionally, the optimal radiotherapy dose and fractionation schemes were also explored.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;In this retrospective cohort study, 124 patients with ES-SCLC diagnosed at Taizhou Cancer Hospital between January 2019 and November 2023 were categorized into cTRT and non-cTRT groups. We compared the baseline characteristics, treatment processes, and survival outcomes between the two groups. Moreover, cTRT subgroups of different radiotherapy doses and fractionation schemes were formed and compared in terms of baseline characteristics, radiotherapy efficacy and safety, patterns of recurrence after radiotherapy, and survival outcomes. OS was selected as the primary endpoint for observation. Differences in OS between the groups were analyzed using log-rank tests. Univariable and multivariable Cox regression analyses were performed to identify factors correlated with OS in the overall patient cohort.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The baseline characteristics between the two groups (cTRT and non-cTRT) were generally comparable, with the following significant differences: the cTRT group had a lower proportion of females (1.7% &lt;i&gt;vs.&lt;/i&gt; 15.2%, P=0.02), lower levels of neuron-specific enolase (NSE, median: 15.87 &lt;i&gt;vs.&lt;/i&gt; 32.00 ng/mL, P=0.009), and higher sodium concentrations (median: 140.50 &lt;i&gt;vs.&lt;/i&gt; 138.25 mmol/L, P=0.01). Additionally, the cTRT group underwent more first-line treatment cycles (median: 4.00 &lt;i&gt;vs.&lt;/i&gt; 3.00, P=0.001). Compared with the non-cTRT group, the cTRT group had a longer OS [median survival 15.5 &lt;i&gt;vs.&lt;/i&gt; 10.5 months; hazard ratio (HR) =2.0497; 95% confidence interval (CI): 1.3548-3.1010; P&lt;0.001]. There were no significant differences in survival outcomes associated with the different radiotherapy dosage or fractionation schedules. The most common adverse event was neutropenia, but no severe treatment-related deaths occurred. Multivariable Cox analysis revealed that the sodium concentration (HR =0.8751; 95% CI: 0.7944-0.9642; P=0.007), initial treatment response (HR =0.7022; 95% CI: 0.4949-0.9964; P=0.048), total number of systemic treatment cycles (HR =0.5501; 95% CI: 0.3618-0.8364; P=0.005), and whether to receive cTRT (HR =1.7484; 95% CI: 1.1033-2.7708; P=0.02) were independent prognostic factors for OS.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;cTRT improved the OS of patients with ES-SCLC and exhibited manageable associated toxicity.
