Correction: Treatment outcomes of radiotherapy with concurrent weekly cisplatin in older patients with locally advanced head and neck squamous cell carcinoma (Discover Oncology, (2023), 14, 1, (226), 10.1007/s12672-023-00844-7)

After publication an error was found by the authors in the progression-free survival (PFS) analysis. In the original analysis, deaths were not included in the progression-free survival (PFS) analysis as events, as noted in the Methods section. The errors caused by this are listed in this correction article. This analytical error does not affect the interpretation and conclusions of the original article [1]. Incorrect The 3-year OS, PFS, and CSS were 80.9% (95% confidence interval [CI]: 64.8–90.7), 68.3% (95% CI 51.8–81.2), and 85.0% (95% CI 68.7–93.4), respectively. The 3-year OS, PFS, and CSS were 80.9% (95% confidence interval [CI]: 64.8–90.7), 68.3% (95% CI 51.8–81.2), and 85.0% (95% CI 68.7–93.4), respectively. Correct The 3-year OS, PFS, and CSS were 80.9% (95% confidence interval [CI]: 64.8–90.7), 58.9% (95% CI: 42.7–73.3), and 85.0% (95% CI: 68.7–93.4), respectively.

Incorrect With a median follow-up period of 36 months (range: 1–156), the 3-year and 5-year OS rates were 80.9% (95% CI 64.8–90.7) and 69.7% (51.6–83.2), respectively (Fig. 1A).

In an analysis limited to 12 patients aged ≥ 75 years, the median follow-up period was 32.5 months (range: 2–77). The 3-year and 5-year OS rates were the same, 87.5% (95% CI 46.3–98.3), and the 3- and 5-year PFS rates were also the same, 53.3% (95% CI 53.3–98.6) (Fig. 2A, B).
