Splenectomy
The theory behind splenectomy is that in JMML, the spleen acts as a trap for leukemic cells, which leads to their enlarged size. The fear is that since radiation and chemotherapy attack active leukemia cells rather than dormant ones, if the spleen is not removed it may harbor JMML cells that can later lead to relapse. The impact of splenectomy for post-transplant relapse, though, is unknown. The COG JMML Study includes splenectomy as a standard treatment for all clinically stable patients. The EWOG-MDS JMML Study allows each child’s physician to determine whether or not a spleenectomy should be done, and large spleens are commonly removed prior to bone marrow transplant. When a splenectomy is scheduled, JMML patients are advised to receive vaccines against Streptococcus pneumoneae and Haemophilus influenza at least 2 weeks prior to the procedure. Following splenectomy, penicillin may be administered daily in order to protect the patient against bacterial infections that the spleen would otherwise have protected against; this daily preventative regimen will usually continue until the patient is an adult.
