Erratum to: Solitary plasmacytoma: population-based analysis of survival trends and effect of various treatment modalities in the USA

Erratum

After publication of the original article [1] the authors found the following errors had occurred:

1. Figure titles were incorrect:

• Figure 1 should be titled: Kaplan-Meier survival curve comparing sequence of RT in patients who received RT and surgery (Fig. 1)

• Figure 2 should be titled: Kaplan-Meier survival curve comparing patients who received RT vs. no RT (Fig. 2)

• Figure 3 should be titled: Kaplan-Meier survival curve comparing patients who received surgery vs. those that did not (Fig. 3)

• 2.In Table 6, all P values should be <0.001 instead of >0.001 (Table 6)
