Abstract
PURPOSE Therapy-related myelodysplastic syndrome and acute leukemias (t-MDS/AL) are a major cause of nonrelapse mortality among pediatric cancer survivors. Although the presence of clonal hematopoiesis (CH) in adult patients at cancer diagnosis has been implicated in t-MDS/AL, there is limited published literature describing t-MDS/AL development in children. EXPERIMENTAL DESIGN We performed molecular characterization of 199 serial bone marrow samples from 52 patients treated for high-risk neuroblastoma, including 17 with t-MDS/AL (transformation), 14 with transient cytogenetic abnormalities (transient), and 21 without t-MDS/AL or cytogenetic alterations (neuroblastoma-treated control). We also evaluated for CH in a cohort of 657 pediatric patients with solid tumor. RESULTS We detected at least one disease-defining alteration in all cases at t-MDS/AL diagnosis, most commonly TP53 mutations and KMT2A rearrangements, including involving two novel partner genes (PRDM10 and DDX6). Backtracking studies identified at least one t-MDS/AL-associated mutation in 13 of 17 patients at a median of 15 months before t-MDS/AL diagnosis (range, 1.3-32.4). In comparison, acquired mutations were infrequent in the transient and control groups (4/14 and 1/21, respectively). The relative risk for development of t-MDS/AL in the presence of an oncogenic mutation was 8.8 for transformation patients compared with transient. Unlike CH in adult oncology patients, TP53 mutations were only detectable after initiation of cancer therapy. Last, only 1% of pediatric patients with solid tumor evaluated had CH involving myeloid genes. CONCLUSIONS These findings demonstrate the clinical relevance of identifying molecular abnormalities in predicting development of t-MDS/AL and should guide the formation of intervention protocols to prevent this complication in high-risk pediatric patients.

Abstract
Peritoneal carcinomatosis (PC) is considered incurable, and more effective therapies are needed. Herein we test the hypothesis that GPA33-directed intracompartmental pretargeted radioimmunotherapy (PRIT) can cure colorectal peritoneal carcinomatosis. Nude mice were implanted intraperitoneally with luciferase-transduced GPA33-expressing SW1222 cells for aggressive peritoneal carcinomatosis (e.g., resected tumor mass 0.369 ± 0.246 g; n = 17 on day 29). For GPA33-PRIT, we administered intraperitoneally a high-affinity anti-GPA33/anti-DOTA bispecific antibody (BsAb), followed by clearing agent (intravenous), and lutetium-177 (Lu-177) or yttrium-86 (Y-86) radiolabeled DOTA-radiohapten (intraperitoneal) for beta/gamma-emitter therapy and PET imaging, respectively. The DOTA-radiohaptens were prepared from S-2-(4-aminobenzyl)-1,4,7, 10-tetraazacyclododecane tetraacetic acid chelate (DOTA-Bn). Efficacy and toxicity of single- versus three-cycle therapy were evaluated in mice 26-27 days post-tumor implantation. Single-cycle treatment ([177Lu]LuDOTA-Bn 111 MBq; tumor dose: 4,992 cGy) significantly prolonged median survival (MS) approximately 2-fold to 84.5 days in comparison with controls (P = 0.007). With three-cycle therapy (once weekly, total 333 MBq; tumor dose: 14,975 cGy), 6/8 (75%) survived long-term (MS > 183 days). Furthermore, for these treated long-term survivors, 1 mouse was completely disease free (microscopic "cure") at necropsy; the others showed stabilized disease, which was detectable during PET-CT using [86Y]DOTA-Bn. Treatment controls had MS ranging from 42-52.5 days (P < 0.001) and 19/20 mice succumbed to progressive intraperitoneal disease by 69 days. Multi-cycle GPA33 DOTA-PRIT significantly prolongs survival with reversible myelosuppression and no chronic marrow (929 cGy to blood) or kidney (982 cGy) radiotoxicity, with therapeutic indices of 12 for blood and 12 for kidneys. MTD was not reached.

Abstract
The SSX genes are members of the family of cancer/testis antigens that encode tumor-associated antigens recognizable by autologous cytolytic T lymphocytes. Their expression is common in tumors of diverse lineages and absent in normal tissues except testis and thyroid. In this study, sixty-seven neuroblastomas (NB) (12 stage 1, 13 stage 2, 12 stage 3, 12 stage 4S and 13 stage 4) were examined by RT-PCR and a sensitive chemiluminescent detection method for SSX-2 and SSX-4 expression. Seventy-two percent (13/18) of stage 4 NB expressed SSX-2 and 67% (12/18) expressed SSX-4. SSX-2 and SSX-4 positivity correlated with metastatic NB stage 4 (p=0.02 and p=0.006, respectively). Sensitivity experiments showed SSX-2 detection was one tumor cell in 106 normal cells, and one in 104 for SSX-4. All normal tissues (n=6), with the exception of testis, normal bone marrow (BM, n=12) and normal peripheral blood (PBL, n=10) were negative for SSX-2 and SSX-4 expression. Thirty-two BM and 14 PBL obtained from 35 stage 4 NB patients at 24 months from their diagnosis were evaluated for SSX-2 expression. Unlike another cancer/testis antigen, GAGE, only one BM sample was positive, and no prognostic utility could be established. Further investigation of SSX expression at other relevant time points is warranted.

Abstract
Abstract
Fowl γ-globulin, when chemically conjugated to GLØ or GL, functions as a T-dependent immunogenic carrier and stimulates anti-GLØ and anti-GL antibody production in nonresponder mice. The conjugation procedure utilizes the Schiff base reaction. The anti-GL and anti-GLØ responses were detected by hemagglutination and hemolytic plaque assays by using GL-coated erythrocytes. The coupling of GL to erythrocytes utilizes a novel procedure in which a palmitoyl derivative of GL is adsorbed onto red blood cells. The optimal conditions for preparing the palmitoyl derivative and for coupling to SRBC are presented. With the hemolytic plaque assay, we have verified that GLØ responder animals make both IgM and IgG responses, whereas nonresponder mice fail to make either IgM or IgG plaque-forming cells.
