I thank Professor J R A Mitchell for constructive criticism of this paper, Miss Jayne Patrick for typing the manuscript, and the department of clinical chemistry for the biochemical estimations.

We calculated standardized incidence rates (SIRs) for all subsequent hematologic and nonhematologic malignancies for MM patients diagnosed before/after 1995 (introduction of high-dose melphalan/autologous stem cell transplantation [HDM-ASCT]) and 2000 (introduction of immunomodulatory drugs [IMiDs]), respectively. MM patients had an 11.51-fold (95% confidence interval: 8.19-15.74) increased risk of acute myeloid leukemia (AML)/myelodysplastic syndromes (MDS); risk was very similar before/after 1995 and 2000, respectively. MGUS patients had an 8.01-fold (5.40-11.43) increased risk of AML/MDS. Risk was confined to IgG/IgA, while no IgM MGUS patients developed AML/MDS; patients with monoclonal-protein (M-protein) concentrations > 1.5 g/dL (SIR = 11.12; 3.61-25.96) had higher r...

In the 30 children evaluable for antitumor effect, there were 7 complete, 12 partial, and 3 minor tumor responses. Wilms&amp;amp;amp;amp;amp;#39; tumor and rhabdomyosarcoma responded best. There were no therapy-related deaths. Severe neutropenia (PMN less than 500/mmc) developed after 29 out of the 45 evaluable courses and lasted a median of 8 days; during periods of neutropenia 8 episodes of fever occurred, 1 of which was caused by streptococcal sepsis. Platelet levels were depressed to less than 50,000/mmc after 17/45 cycles and this thrombocytopenia lasted a median of 8 days. No neurological toxicity occurred. One case developed acute renal failure. A hearing deficit for high frequencies was documented in 14/22 patients evaluated after the first cycle and in all cases after the subsequent cycles; the deficits correlated with the total dose of CDDP administered. High-dose cisplatin and VP16 is an effective association in children with advanced cancer, but cumulative dosage is limited by ototoxicity.

Nine had resistant and two relapsed neuroblastoma. Nine children had previously been treated with cisplatinum at conventional doses; nine had not received cyclophosphamide and ten had not received vincristine. Nine of eleven patients had a good response to treatment; six are presently alive in continuous complete remission 11-23 months (median 13 months) after diagnosis. Toxicity was moderate: no child showed either severe myelotoxicity or clinical or laboratory evidence of nephrotoxicity. No child had clinically significant ototoxicity. In six children audiometry showed hearing loss for high frequencies after the third cycle of treatment. It is concluded that OC-HDP regimen could be considered as a first-line treatment for advanced neuroblastoma.

The authors report a series of 110 infants with disseminated neuroblastoma with disease diagnosed between March 1976 and February 1991 in 21 institutions participating in the Italian Cooperative Group on Neuroblastoma (ICGNB). Of the 110 infants, 34 had Stage IV disease, and 76 had Stage IV-S disease. The 5-year survival probability was 77% for all patients, 71% for those with Stage IV disease, and 81% for those with Stage IV-S disease. Of the 34 infants with Stage IV disease, the 9 who were 5 months or younger at the time of disease diagnosis are all alive (1 with active disease) at 7-143 months after diagnosis, whereas of the 25 infants who were 6-11 months of age at the time of disease diagnosis, 10 have died. Of the 76 infants with Stage IV-S disease, 12/64 who were 5 months of age or younger at the time of disease diagnosis died (mostly of massive hepatomegaly); 9 of these deaths occurred in infants with disease diagnosed before they were 2 months old, whereas 1 death occurred in the 12 infants with disease diagnosed when they were 6-11 months old. Four infants with Stage IV-S disease achieved complete disease remission and subsequently had relapse of disease. High levels of serum LDH and low urinary excretion of vanillylmandelic acid were associated with worse prognosis. The authors suggest that infants older than 6 months of age who have Stage IV disease require aggressive therapy. For infants with disease diagnosed before they are 2 months old, Stage IV-S disease may have a worse prognosis than Stage IV disease.

Seventeen with no evidence of lymph node involvement in whom tumor resection was complete (Group 1) received no further antitumor therapy. One child died postoperatively; disease recurred in the bone marrow of one child at 52 months, the child subsequently died. Fifteen were alive without disease, giving an 82% actuarial five year survival. Forty-eight children with minimal residual tumor and/or regional lymph node involvement (Group 2) received two 5-day courses of Peptichemio (1.2 mg/kg/d) and the 29 children in this group who were older than 1 year of age at diagnosis were randomized to receive either radiotherapy to the tumor bed in addition or no radiotherapy. In Group 2, ten of the 48 have relapsed: six of 17 with initial lymph node involvement, three of four with tumor rupture at operation, and one of eight with tumor extension to the intervertebral foramen. No relapses were seen in the 19 children with minimal residual tumor confined to the tumor bed. Only one of the 18 Group 2 children who were younger than 1 year of age at diagnosis relapsed. Of the 29 Group 2 children who were older than 1 year of age at diagnosis, five relapses occurred in the 14 who received radiotherapy and four relapses in the 15 who did not receive radiotherapy. All six children with disseminated relapse died. Actuarial 5-year survival in Group 2 is 87%, and actuarial relapse-free survival, 76%.
