We have noticed an error in the progression-free survival of patients with extramedullary plasmacytoma in our article published in Haematologica in January 2020 (doi: HAEMATOL/2019/219295).

The following sentence in the abstract:

“Extramedullary plasmacytoma at relapse had the worst prognosis with a PFS of 13.6 months and overall survival of 11.4 months.”

Should be replaced by:

“Extramedullary plasmacytoma at relapse had the worst prognosis with a PFS of 9.1 months and overall survival of 11.4 months.”

Likewise, on page 205, the following sentence:

“However, if diagnosed at relapse, PFS and OS were 13.6 months and 11.4 months for EMP compared to 20.9 months (P=0.249) and 39.8 months (P=0.093) for PO, respectively (Table 2 and Figure 1).”

Should be replaced by:

“However, if diagnosed at relapse, PFS and OS were 9.1 months and 11.4 months for EMP compared to 20.9 months (P=0.249) and 39.8 months (P=0.093) for PO, respectively (Table 2 and Figure 1).”

The error was also present in Table 2.

The corrected Table 2 is shown below.

Table 2.

Comparison of response, survival outcomes of extramedullary plasmacytomas (EMP) or paraosseous (PO) patients either at diagnosis or at relapse.
