The team found no major difference in survival between the two groups.
There are some caveats, however, Rajkumar said. For one, few patients took part in the study, lowering its statistical power. For another, many of the patients who received stem-cell transplants got them at facilities that didn't have much experience in the procedure, which is very complicated, he said.
Considering that, it's possible that treatment with stem-cell treatments may be a better option in some cases, Rajkumar said.
