The correct version of the figures and tables as well as the updated Results and Discussion sections are given below.

Error in Results section

On page 5, the second paragraph of the first column reads:

“The whole cohort was analyzed using log-rank tests and univariate Cox proportional hazards models, which revealed that age, years of diagnosis, laterality, primary site, pathological type, and chemotherapy had an effect on DSS.”

The sentence should read:

“The whole cohort was analyzed using log-rank tests and univariate Cox proportional hazards models, which revealed that age, years of diagnosis, primary site, pathological type, and chemotherapy had an effect on DSS.”

Error in Discussion section

On page 6, the first sentence of the first paragraph currently reads:

“In line with previous studies [2] (reference 26 in the original article], this study revealed a mean age at diagnosis of 62.5 years.”

The sentence should read:

“In line with previous studies [2] (reference 26 in the original article], this study revealed a mean age at diagnosis of 66.1 years.”

The original article [1] has been corrected.

The authors apologise for these errors.
