Correction to: International Journal of Clinical Oncology (2022) 27:1828–1838 https://doi.org/10.1007/s10147-022-02232-7

In the original publication, under section: Secondary end points, the sentence starting with: “KM estimated…” should read as:

KM estimated median DoR was not reached (95% CI 13.9–not reached) in patients who had confirmed responses.

In Results section, under heading Secondary end points, the sentence starting with: "Among..." should read as: Among the 31 patients with confirmed response by IRC, median time to response was 1.8 months (range, 0.95–12.9). In Table 2 the value of the entry: Duration of response, months, median (range) has been updated. The revised Table 2 is given in this Correction.

Table 2 Rates of systemic and intracranial objective response by IRC assessment

The original publication has been corrected.
