Correction to: Journal of Neuro-Oncology https://doi.org/10.1007/s11060-019-03279-9

The following discrepancies and errors were found in the original publication:

  • As correctly specified in Table 1, the male PCNSL patients treated with HD-MTX made up 46% of that group (not 54% as specified in the Abstract and the text of the Results section).

  • As correctly specified in the Results section (Table 2 and text), the average first detected WMC score was 0.8 (± 0.9) (mean, ± SD) in the HD-MTX group; not 1.5 (± 0.6) as specified in the Abstract. Also, the term ‘non-zero’ in the Abstract and in the text of the Results section should not have been used here.

  • As correctly specified in Table 2, the p-value for the Overall WMC score is 0.0048; not 0.04 as specified for the average WMC score in the text in the Results section.

  • In the first column of Table 2, the word 'years' in the bottom entry should read 'months'.

  • In the Results section, the second sentence in the second paragraph should read as follows: "Median time to detect WMC was shorter in the HD-MTX-R group compared to the HD-MTX group".
