Nineteen children with Hodgkin's disease were immuized with dodecavalent pneumococcal vaccine; the efficacy of vaccination, the duration of response, and the significance of the time of immunization in relation to splenectomy and subsequent irradiation and chemotherapy were investigated. Eight children were immunized before splenectomy, and 11 were immunized after splenectomy, irradiation, and chemotherapy. All children were irradiated, and all but two received chemotherapy with MOPP (nitrogen mustard, vincristine sulfate, procarbazine, and prednisone). Sera were assayed for antibodies to the 12 polysaccharide types in the vaccine. The group of children immunized before splenectomy had a significant antibody response to 67% of the antigens tested, whereas the group immunized after splenectomy responded to 40% of the antigens (P less than 0.0001). The duration of response was variable. Pneumococcal vaccine was more likely to provoke an immunologic response if administered before splenectomy than if administered after splenectomy, irradiation, and chemotherapy; however, the response was not uniform. A response to one antigen did not necessarily imply a response to other antigens. In the absence of a readily available assay to determine a protective antibody response, one cannot rely on the vaccine as the sole means of preventing pneumococcal infections in asplenic children with Hodgkin's disease.

Allogeneic bone marrow transplant in pediatric patients with high-risk hematopoietic malignancies early in the course of their disease.

PURPOSE: The purpose of this study was to investigate the role of bone marrow transplant (BMT) early in the course of disease for pediatric patients with high-risk leukemia using a preparatory regimen of fractionated total body irradiation (FTBI) and etoposide (VP-16). PATIENTS AND METHODS: Those studied were 33 patients aged < or =18 years with either acute leukemia in first complete remission (CR) (n = 29) or chronic myelogenous leukemia (CML) in first chronic phase (n = 4) who received 1,320 cGy FTBI followed by high-dose VP-16 (60 mg/kg) as a preparatory regimen for BMT from matched sibling donors. Patients with acute leukemia included 18 with acute nonlymphocytic leukemia (ANLL), one with biphenotypic acute leukemia (BAL), and 10 with selected "high-risk" acute lymphocytic leukemia (ALL). Patients with ALL were selected for a high risk for recurrence: those who failed standard remission induction chemotherapy, had a t(9;22) or t(4;11) chromosomal translocation, or had certain clinical high-risk features. RESULTS: At the time of analysis, 28 patients are alive, all of them in continued complete remission for 1.1-7.8 years (median, 5.3 years; mean, 4.9 years). The Kaplan-Meier projected event-free survival (EFS) is 84.5% at 7 years, and the actuarial recurrence hazard is 6.5%. All surviving patients have a performance status of >80%. CONCLUSION: This result of early BMT in a two-institution study of pediatric patients with hematopoietic malignancies suggests that (a) matched sibling allogeneic BMT after conditioning with FTBI and high-dose VP-16 is an excellent treatment for pediatric patients with high-risk leukemia, and (b) children may have a better prognosis than adults treated with allogeneic BMT. Larger multiinstitutional cooperative trials for pediatric patients are needed to confirm this result.

Soft-tissue sarcomas of the diaphragm: a report from the Intergroup Rhabdomyosarcoma Study Group from 1972 to 1997.

PURPOSE: To describe clinical details and outcome of children and adolescents with primary sarcomas of the diaphragm treated on Intergroup Rhabdomyosarcoma Studies (IRS) I through IV. PATIENTS AND METHODS: We reviewed the records of 15 patients with sarcoma of the diaphragm who were entered on IRS Group protocols between 1972 and 1997. Patient ages at diagnosis ranged from 0.5 to 20 years (median, 13 yrs), and 10 were girls. Patients had chest pain, dyspnea, and/or coughing, decreased breath sounds, and occasionally hepatomegaly. RESULTS: Localized, gross residual disease after initial surgery was present in 10 patients, and five had metastases at diagnosis (pleura, 3; pericardium, 1; lungs and bones, 1). Tumor subtypes were alveolar rhabdomyosarcoma (RMS) in five cases, embryonal RMS in three, undifferentiated sarcoma in three, extraosseous Ewing sarcoma in three, and unclassified sarcoma in one. Treatment consisted of radiation therapy to the primary tumor and metastases when feasible, and combination chemotherapy with vincristine, actinomycin D, and cyclophosphamide with or without doxorubicin, ifosfamide, cisplatin, and etoposide. Ten patients achieved complete remission (67%), four obtained a partial remission, and one was improved. Five patients (33%) are continuously failure-free and alive at a median of 8.8 years from diagnosis (range, 1.1-15 yrs). However, the other 10 patients experienced relapse at 0.3 to 2 years from start of therapy (median, 1 yr). Sites of relapse were local in five, distant in three, and combined in two. Death after relapse occurred at 0.39 to 2.6 years (median, 1.6 yrs) from diagnosis. CONCLUSIONS: Sarcomas of the diaphragm are generally deemed unresectable at diagnosis and/or are metastatic. Most of them are not embryonal rhabdomyosarcomas. Treatment with more effective primary chemotherapy to shrink the tumor, followed-up by surgical resection and radiation therapy, should improve the prognosis for patients with sarcomas arising in the diaphragm, especially for the majority who have localized tumors.

Nutritional support as an adjunct to radiation therapy.

Patients with malignancies which are treated with therapeutic radiation are at risk for nutritional problems, both from their underlying malignancy as well as from their treatment. These effects may be acute or chronic and relate to the site of the tumor and regions irradiated. There is a large experience with nutritional intervention in irradiated patients, including oral feedings and enteral and parenteral nutritional support. The indications for the specific administration of nutritional support during radiotherapy depend on the nutritional status of the patient and the area irradiated, as well as the individual prognosis. Patients who are malnourished at the time of treatment are most likely to profit from nutritional intervention. To date, prospective randomized trials of nutritional support in patients undergoing radiotherapy fail to show a benefit of routine adjuvant nutritional intervention in terms of improved response and tolerance to treatment, improved local control or survival rates, or reduction of complications from therapy.

Special nutritional needs of children with malignancies: a review.

Nutrition support for the patient with cancer is an important part of the overall treatment regimen. Nutrition support for the child with cancer poses a special challenge. For the purpose of reviewing the special nutritional needs of children with cancer, a Task Force was formed by the American Academy of Pediatrics to review the current state of knowledge. The work of the Task Force was supported by the Food and Drug Administration through its Liaison Representative, Joginder Chopra, M.D., Staff support from the Academy was provided by Jean D. Lockhart, M.D., This review is prepared from the Task Force Report to the FDA. It is designed to review factors enhancing nutritional risks for the child with cancer and to discuss nutritional intervention strategies and their efficacies.

Childhood cancer: patterns of protocol participation in a national survey.

Cancer is still the chief cause of death by disease in children, ages one to 14. As improved survival rates have been reported for pediatric cancer patients who are treated on controlled clinical trials, it is important to understand the national utilization of such protocols. In 1993, a survey of childhood cancer was conducted by the Commission on Cancer of the American College of Surgeons. Data regarding type of disease, protocol participation, age, sex, race, insurance, and geographical region were voluntarily submitted by more than 200 hospital cancer registries. Included in this study were 2,208 children and adolescents 21 years of age or younger who were diagnosed in 1987, and 2,293 who were diagnosed in 1992. Pediatric centers (i.e., members of the Pediatric Oncology Group or Children's Cancer Group) submitted 55.1% of the cases and other institutions, 44.9%. It was found that more patients treated at pediatric centers were on protocols (53.8%) than were those treated at other institutions (25.1%). In general, the younger the patient (five years of age or younger), the greater the chance of being on protocol (pediatric centers, 63.7%; others, 42.0%), with very poor adolescent protocol participation (pediatric centers, 34.8%; others, 12.1%). Nevertheless, overall protocol participation was still lower than expected, even in children younger than five years of age, and adolescent participation in controlled clinical trials was low and similar to adult figures. The percentage of childhood cancer cases seen at pediatric centers was smaller than in other series. It was concluded that pediatric cancer centers need to continue to encourage patient participation in controlled clinical trials, with special emphasis on adolescents.

The Janeway lecture. Hodgkin's disease--finding the balance between cure and late effects.

PURPOSE: The purpose of this review is to summarize the Stanford experience in Hodgkin's disease, the late effects of treatment, and strategies to improve management to maximize cure and decrease late effects in these patients. PATIENTS AND METHODS: Between 1960 and 1999, 2617 consecutive patients with Hodgkin's disease have been seen, treated, and rigorously followed at Stanford. This population includes patients of all ages and stages of disease. The database summarizing this experience serves as the source of survival and mortality data over 4 decades. Two thousand two hundred thirty-two of the population comprise the group evaluated for secondary cardiac disease. Two thousand one hundred sixty-two patients have been evaluated for risk of secondary leukemia, non-Hodgkin's lymphoma, and solid tumors. Eight hundred eighty-five women were evaluated for secondary breast cancer, prompting a subsequent analysis of risk of secondary cancer among 694 pediatric patients. RESULTS: The probability of cure of Hodgkin's disease has dramatically improved over the past 40 years. Today, 94% of patients are expected to survive. Among those who do not survive, approximately half die of Hodgkin's disease, 20% of new cancers, and 14% of cardiovascular complications. Modifications in patient management and treatment have greatly reduced the serious late effects observed from prior therapy. With current combined-modality therapy using moderate doses of involved field of radiation and limited cycles of multiagent, risk adapted chemotherapy, serious cardiac complications and development of secondary cancers are expected to be greatly reduced. The Stanford 25-year pediatric Hodgkin's disease experience reveals that survival in favorable early-stage disease exceeds 95%. Newer protocols for children with advanced-stage disease continue to show these excellent survival rates and promise less late morbidity. Adult protocols using the risk-adapted Stanford V combined-modality program now parallel the pediatric experience, with greater than 90% survival in these patients. DISCUSSION: Thus today the likelihood of cure of Hodgkin's disease greatly exceeds the risk of late effects, a goal both Dr. Henry Janeway and Madame Marie Curie emphasized and taught from first-hand experience.
