Correction to “Non‐Small Cell Lung Cancer Patients With Tumors ≤ 2 cm Are Suitable for Wedge Resection or Segmentectomy: A Real‐World Study”

In the originally published version of the above article, there was a data entry error in the abstract, Figures 2–4, Tables 3, 7, and 8, and the corresponding data descriptions in the main text. Specifically, the data for OS and LCSS were inadvertently swapped during table preparation.

The positions that should have presented OS data were incorrectly filled with LCSS data. The positions that should have presented LCSS data were incorrectly filled with OS data.

The author reviewed the original data and corrected the tables and related text. All OS and LCSS data, as well as their corresponding figures in the text, have now been placed in their respective correct positions as detailed below:

Abstract (Results)

A total of 640 patients were enrolled (wedge resection: 295; segmentectomy: 345). After IPTW, no difference in baseline characteristics was observed between the two groups. Additionally, long‐term outcomes did not significantly differ between the groups. However, compared with segmentectomy, wedge resection was associated with a shorter operation duration (p < 0.001), less intraoperative blood loss (p < 0.001), fewer complications (p < 0.001), and shorter postoperative stay (p = 0.047). In the subgroup with a consolidation‐to‐tumor ratio (CTR) > 0.25, segmentectomy resulted in longer OS (p = 0.036), LCSS (p = 0.046) as well as higher 5‐year OS (p = 0.015), 5‐year RFS (p = 0.023), and 5‐year LCSS (p = 0.045).

3.3.1 Comparison of Long‐Term Survival Outcomes

A total of 640 patients completed long‐term follow‐up. The median follow‐up was 86.5 months for the wedge resection group and 88.4 months for the segmentectomy group. The 5‐year OS rates were 94.91% for the wedge resection group and 96.52% for the segmentectomy group (p = 0.314). The 5‐year RFS rates were 93.89% versus 93.04% (p = 0.663), and the 5‐year LCSS rates were 96.61% versus 97.39% (p = 0.562) for the wedge resection and segmentectomy groups, respectively. Similarly, after IPTW adjustment, no significant differences in survival outcomes were observed between the two groups: OS (p = 0.790), RFS (p = 0.982), LCSS (p = 0.759), 5‐year OS (p = 0.129), 5‐year RFS (p = 1.000), and 5‐year LCSS (p = 0.244). The long‐term outcomes are summarized in Table 3. The Kaplan–Meier survival curves for OS, RFS, and LCSS are shown in Figure 2.

3.4.2 Subgroup With a CTR > 0.25

Patients with NSCLC with a CTR > 0.25 were selected for subgroup analysis. The total sample size before matching was 89 patients, including 42 who underwent wedge resection and 47 who underwent segmentectomy. The results of the balance analysis before matching revealed that compared with the wedge resection group, the segmentectomy group had significantly longer OS (p = 0.005), RFS (p = 0.045), LCSS (p = 0.010), 5‐year OS (p = 0.002), 5‐year RFS (p = 0.005), and 5‐year LCSS (p = 0.001). The results of the balance analysis after matching revealed that compared with the wedge resection group, the segmentectomy group had significantly longer OS (p = 0.036), RFS (p = 0.061), LCSS (p = 0.046), 5‐year OS (p = 0.015), 5‐year RFS (p = 0.023), and 5‐year LCSS (p = 0.045), as shown in Table 8. The Kaplan–Meier curves for OS, RFS, and LCSS in the wedge resection and segmentectomy groups for patients with a CTR > 0.25 are shown in Figure 4.
