Hypofractionated accelerated radiotherapy in osteogenic sarcoma.

A method of hypofractionated accelerated radiotherapy (3 weekly fractions of 6 Gy over 2 weeks to a total tumor dose of 36 Gy) was used as single modality in 14 patients with osteogenic sarcoma for palliative treatment of the primary tumor site (six cases) or skeletal metastases (15 sites). A durable response, radiologically assessed, was obtained in 17 of the 21 (81%) irradiated sites. When this irradiation modality was combined with chemotherapy, to treat patients presenting with synchronous metastases (eight cases) or refusing amputation (five cases), a radiologically assessed response was observed in 12 of 13 (92%). In no case did a local recurrence occur before surgery or death because of progressive disease elsewhere. Of the seven patients who later had to undergo ablative surgery, a 100% and 95% tumor necrosis was observed in 6 and 1, respectively. Because of intralesional resection of primary osteogenic sarcoma after preoperative chemotherapy, seven additional patients were irradiated. None recurred at the level of the primary site. Although effective in inducing remission of osteogenic sarcoma, this irradiation method produced severe damages to normal tissues in a high proportion of patients.

Questionable role of CNS radioprophylaxis in the therapeutic management of childhood rhabdomyosarcoma with meningeal extension.

A series of 15 consecutive children with head and neck nonorbital rhabdomyosarcoma (RMSA) with meningeal extension were prospectively treated with chemotherapy consisting of Adriamycin (doxorubicin; Adria Laboratory, Columbus, OH) (ADM), vincristine (VCR), cyclophosphamide (CPM), and dactinomycin (DACT) followed by radiotherapy (60 Gy) to the primary tumor volume, along with intrathecal methotrexate (IT MTX). Thirteen of 15 responded to preradiation chemotherapy. Four of 13 relapsed. Relapse occurred at the level of the primary tumor in three of four. The 3-year progression-free survival (PFS) was 59%, similar to that achieved in a previous series treated with a comparable therapeutic approach that also included whole-brain radiotherapy as a prophylaxis of possible occult meningeal seeding. It is concluded that CNS prophylaxis with radiotherapy is questionable in the management of childhood RMSA with meningeal extension.

Advanced neuroblastoma: results of two treatment programs including sequential hemibody irradiation.

Results of two consecutive treatment programs for advanced neuroblastoma, including sequential hemibody irradiation, are analyzed and compared. The first treatment program (I-TP) included one single-fraction (7 Gy) irradiation to the upper and lower halves of the body as consolidation of remission achieved by previous chemotherapy with CDDP and VP16. A fractionated technique (2 Gy daily for 4 consecutive days to each hemibody) was used in the second treatment program (II-TP) for children in remission following a combination of CDDP + VP16 and ADM + VCR + CTX. In both treatment programs, chemotherapy was continued according to the same pre-radiation regimen following the two sessions of hemibody irradiation. Overall response rate to pre-radiation chemotherapy was 84% and 60% for I-TP and II-TP, respectively. Thirty-month overall progression-free survival was 0 for I-TP and 20% for II-TP. No treatment-related fatalities occurred. In the subsets of patients who reached complete or good partial remission during the pre-radiation chemotherapeutic phase, 30-month progression-free survival in I-TP and II-TP was 0 and 33%, respectively. The role of fractionated hemibody irradiation in prolonging the progression-free survival can be inferred.

Second malignant neoplasms following childhood Hodgkin's disease: treatment and splenectomy as risk factors.

The risk of second malignant neoplasm (SMN) was evaluated in 979 children with Hodgkin's disease. This cohort was diagnosed between 1955 and 1979 at one of the institutions of the Late Effects Study Group. Solid tumors, non-lymphocytic leukemia, and non-Hodgkin's lymphoma (NHL) developed in 18, 17, and 3 patients, respectively. The estimated cumulative probability of developing any SMN was 2% at 5 years from diagnosis, 5% at 10 years, and 9% at 15 years. The incidence is ninefold greater than the risk of acquiring cancer in 19 year-olds, the median age at which the diagnosis of SMN was made in this study population. For leukemia and NHL the corresponding probabilities were 1%, 3%, and 4% for the group as a whole but were increased (2%, 6%, and 8%) in patients who had suffered one or more recurrences. In order to analyze the risk of leukemia and NHL associated with alkylating agent chemotherapy, each patient was assigned a score of one for each alkylating agent administered for a 6-month period. Scores of 2, 4, 6, and 8 were associated with probabilities of leukemia or NHL of 2%, 3%, 6%, and 10%, respectively. In a multivariate analysis for leukemia/lymphoma that included AAD score, stage, and splenectomy, the effect of AAD score and splenectomy did not change substantially compared to the univariate results. AAD score remained statistically significant (P = .0001), and splenectomy was of borderline significance (P = .09). Of the 18 solid tumor SMNs, 15 developed within the field of radiation, and one other developed in tissue irradiated 34 years earlier for hemangioma. This study of a large and unselected group of children with Hodgkin's disease who received a variety of therapies demonstrates that children are as likely as adults to develop acute leukemia after alkylating agents and solid tumors in the field of radiation therapy.

Late deaths and second primary malignancies among long-term survivors of childhood cancer: an Italian multicentre study.

A multicentre registry of children who had been successfully removed from therapy for some common childhood cancers (Hodgkin's disease, non-Hodgkin's lymphoma, neuroblastoma, nephroblastoma, acute lymphatic leukaemia and other leukaemias) was established in Italy in 1981. The present study describes mortality and occurrence of second primary malignancies (SPMs) among 1467 children who were alive when the registry was established. Follow-up ended on December 31, 1983 for mortality and 1 year later for the occurrence of SPMs. Sixty-seven deaths were recorded, 11 of which were due to causes other than progression of the original disease. Eleven incident SPMs were identified (i.e. 3 acute myeloid leukaemias, 3 thyroid carcinomas, 1 bilateral breast carcinoma, 1 liver malignant mesenchymoma, 1 astrocytoma, 1 chondrosarcoma and 1 osteosarcoma) corresponding to an incidence rate of 2.1/1000 patient-years at risk. Anecdotal reports were collected regarding 2 further SPMs (a thyroid carcinoma and a myeloid leukaemia) as well as several benign tumours, including 2 mammary fibroadenomas.

Long-term evaluation of surgery followed by adjuvant adriamycin in osteogenic sarcoma.

From 1974 to 1978 29 consecutive patients with operable osteogenic sarcoma entered 2 successive clinical trials of adjuvant chemotherapy with adriamycin (ADM) alone. Following radical surgery the first group of 14 patients received ADM 75 mg/sqm q 4 weeks for a total of 8 doses, the second group received ADM 30 mg/sqm daily for 3 days every 4 weeks for a total of 6 cycles. All patients belonging to the first group underwent amputation or exarticulation, while in 4 of 15 of the second group a limb-sparing surgery was performed. Lung tomograms as well as bone scans were not mandatory in the initial work-up. Follow-up ranged from 7 to more than 11 years. Thirteen patients (45%) remain continuously relapse-free survivors: 4 of 14 (28.5%) in the first group and 9 of 15 (60%) in the second group. This difference is not statistically significant. The longest free interval in the 16 patients relapsed was 32 months. Severe toxicity from ADM was observed in only 1 patient and consisted of reversible cardiomyopathy. ADM alone as postoperative adjuvant chemotherapy for osteogenic sarcoma achieved results comparable to those obtained by other contemporary more complex regimens of combination chemotherapy.

Second acute leukemia and other malignancies following treatment for Hodgkin's disease.

The records of 1,329 patients with Hodgkin's disease admitted from 1965 to 1982 were analyzed to assess the relative frequency of second neoplasms. Within a median follow-up of 9.5 years, a total of 68 new cancers were documented. Nineteen cases of acute nonlymphocytic leukemia, 6 cases of non-Hodgkin's lymphomas, and 43 cases with different types of solid tumors were identified. The overall risk of non-Hodgkin's lymphoma was 1.3% +/- 0.6% and of solid tumors was 8.3% +/- 1.5% when basal cell carcinomas were included and 6.7% +/- 1.4% when basal cell carcinomas were excluded. No cases of leukemia were documented in patients treated with radiation therapy only. The 12-year estimate of leukemia by treatment was as follows: chemotherapy only 1.4% +/- 2.3%; radiation plus MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) 10.2% +/- 5.2%; radiation plus ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine) 0; and radiation plus other drug regimens 4.8% +/- 1.6%. The risk of leukemia was particularly high (15.5% +/- 7.4%) in patients who received salvage MOPP after radiation failure. A positive association was also noted between increasing age and risk of second malignancies, especially leukemia. The incidence of second neoplasms can be markedly decreased by deleting from potentially curative therapy certain drugs such as alkylating agents, procarbazine, and nitrosourea derivatives.

Second malignant neoplasms in children: an update from the Late Effects Study Group.

This paper presents an update from the Late Effects Study Group on 292 cases of second malignant neoplasms (SMN) occurring in individuals who were diagnosed with their first neoplasm in childhood. Data are presented regarding the types of first and second neoplasm, the therapy administered, and the predisposing factors. Of the 292 cases (308 SMN), the most common primary was retinoblastoma followed by Hodgkin's disease, soft-tissue sarcomas, and Wilms' tumor. This is not similar to the relative frequency of these cancers in children but rather reflects specific risk factors. Bone sarcomas were the most common SMN among the 208 SMN developing in previously irradiated sites while acute leukemia was the most common SMN unassociated with radiation. Known predisposing conditions to cancer were present in 73 cases; retinoblastoma was the most common of these, followed by neurofibromatosis. There were ten patients with three and three patients with four malignant neoplasms. In 14 patients, the cause of SMN was not suggested by known risk factors as these patients had negative family histories and received no radiation or chemotherapy. We note, therefore, that although most cases of SMN in survivors of childhood cancer can be attributed to radiation, genetic disease, chemotherapy, or combinations of these, unrecognized predisposition or chance may also play a role.

Childhood non-Hodgkin's lymphoma: prognostic relevance of clinical stages and histologic subgroups.

Seventy-nine consecutive children with non-Hodgkin's lymphoma were treated with a uniform intensive radiotherapy-chemotherapy program including high-dose MTX and CNS prophylaxis. Burkitt-type NHL was diagnosed in 44% and convoluted cell-type NHL in 33%. Complete remission rate was 97.5%. Forty-eight of 79 children (61%) remain progression-free after 18-78 months of follow-up. Patients belonging to the Burkitt type subgroup showed a peculiar clinical behavior as well as a significantly shorter survival than the other NHL patients (3-year overall survival rates of 50% vs. 72%, respectively). Clinical stages were related to the progression-free survival. It is concluded that treatment should be tailored according to the histology (Burkitt-type NHL vs. other histologic types) and the clinical stage.

Childhood rhabdomyosarcoma with meningeal extension: results of combined therapy including central nervous system prophylaxis.

Results achieved in two consecutive series of children with rhabdomyosarcoma (RMSA) of the head and neck area, presenting with meningeal involvement, are compared. The first series consisted of 12 children treated with local radiotherapy and with (mostly) polidrug systemic chemotherapy from 1969 to 1977. The second series consisted of 11 children who, besides local radiotherapy and polichemotherapy, received brain radiotherapy (30 Gy) and intrathecal (I.T.) methotrexate (MTX) as central nervous system (CNS) prophylaxis from 1978 to 1980. In the first group, 50% of patients achieved a complete remission and only one child (8%) is surviving relapse-free. In the second group, 91% of patients achieved a complete remission and seven (64%) are surviving relapse-free after a median follow-up of 32 months. The most important reason for failure in the first series was represented by the inability to achieve a persistent local control of the primary tumor. This observation and the higher doses of radiotherapy delivered to the primary tumor in the second series prevent the conclusion that the improved results are attributable entirely to the addition of CNS prophylaxis.

The outcome of Wilms' tumor in infants. Italy 1970-79.

Thirty-four infants under 1 year of age with Wilms' tumor were diagnosed and treated in 14 Italian pediatric oncology units during 1970-79. The 3-year survival rates decreased with higher group unilateral tumors: 95% in group I Wilms' tumor, 75% in group II and 20% in group III. The survival rates for children with group I and II Wilms' tumor were similar for those who were treated with surgery and chemotherapy and those who also received postoperative radiotherapy. During 1975-79 fewer patients with group I Wilms' tumor received radiotherapy (1 of 11) than during 1970-74 (4 of 6, p less than 0.05). All these children are alive at this writing.

Acute renal failure in 11 children with non-Hodgkin lymphoma.

Twelve episodes of acute renal failure (ARF) in 11 children hospitalised for non-Hodgkin lymphoma (NHL) are reported. Six of 11 were classified as abdominal Burkitt type lymphoma, three as lymphoblastic convoluted cell lymphoma, and two as lymphoblastic lymphoma. Oliguria was present in six cases. Duration of ARF ranged from 3 to 23 days. Only one child required peritoneal dialysis. According to possible mechanisms of renal injury patients were divided into three groups: neoplastic renal infiltration (5 cases), uric acid intratubular precipitation (5 cases), treatment-related ARF (2 patients). ARF was always reversible, regardless of aetiology.

Arteriography in childhood tumours.

Percutaneous arteriography was used as the investigation of choice in 121 children with clinically suspected malignancy on 132 occasions. Major complications occurred in 2% of the investigations and misdiagnosis in 10%. The arteriographic information was complementary to that of other, routine, investigations in 18% (25 investigations) but in 70% it was crucial, either ruling out a malignancy or defining its nature, site and size while also serving as a guide for biopsy, surgical manipulation, radiotherapy and/or chemotherapy. Arteriography can shorten the work-up in childhood tumours, especially those of the abdomen, eliminating the need for less informative radiological investigations. However, the complications encountered confirmed the peculiar difficulties and risks of paediatric arteriography and the need for strict case selection and a high degree of skill.

Childhood non-Hodgkin Malignant lymphomas: a clinicopathologic retrospective study.

Between 1968 and 1975, 44 evaluable children under 16 years of age with the histologic diagnosis of non-Hodgkin malignant lymphoma (ML) were treated at the Istituto Nazionale Tumori of Milan. Histologic diagnoses were reclassified as follows: 13 lymphoblastic (others) ML, 15 convoluted cell type lymphoblastic ML, 9 Burkitt type ML, and 7 immunoblastic ML. Only 36% of the patients had stage I and II disease. At diagnosis 25% showed malignant cells in the bone marrow smears. Bone marrow infiltration was particularly frequent in the convoluted cell type lymphoblastic ML and in the lymphoblastic (others) ML subgroups. Burkitt type ML frequently was associated with abdominal lesions and subsequently a high incidence of central nervous system involvement. Patients with stage I and II ML were encountered mostly in the immunoblastic ML subgroup. After 1973 more intensive chemotherapy plus radiotherapy seems to have slightly improved the survival of the patients, except in the Burkitt type ML Subgroup.

[Lymphographic examinations in the pediatric age: review of 413 cases].

From January 1969-June 1978, 413 children less than 15 years of age underwent lymphography at the National Cancer Institute, Milan. Successful lymphatic cannulation was accomplished in 97.7% (769/787) of the sites where it was attempted. No major or permanent complications were encountered. In those children undergoing biopsy of opacified lymph nodes, lymphographic-histologic correlation was 94.5% (104/110). This study has shown that lymphography in childhood can be as readily performed as in the adult and that its diagnostic accuracy is acceptable. As in adults, it is useful in treatment planning, evaluating results of therapy, and detecting recurrent tumor.
