Childhood non-Hodgkin's lymphoma: long-term results of an intensive chemotherapy regimen.

Twenty-nine consecutive children with untreated non-Hodgkin's malignant lymphoma were admitted to Istituto Nazionale Tumori of Milan during the period from 1974 through 1976 and underwent treatment with chemotherapeutic regimens consisting of Adriamycin, Cytoxan, vincristine, and prednisone (two month induction phase) and 6-mercaptopurine, methotrexate, Adriamycin, vincristine, and prednisone (maintenance phase). Each patient, regardless of clinical stage of histologic subgroup, was given the same chemotherapy. The complete response rate was 66%. Due to the high incidence of recurrence of the initial bulky lymphomatous mass and of spread to the central nervous system (CNS), local radiotherapy was given to ten children and CNS prophylaxis (brain radiotherapy + intrathecal methotrexate) to 11 children. After a follow-up period in excess of 40 months, there were five disease-free survivors (17%). Each patient who had a relapse died from the disease. The main reason for first treatment failure was relapse at the level of the primary bulky tumor site or spread to the CNS. This type of CNS prophylaxis did not prevent relapse at this site.

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.

Adjuvant therapies of postsurgical minimal residual disease.

The review summarizes the most recent results obtained with present combined adjuvant strategy for the treatment of resectable cancer. Recent important randomized clinical trials, either unicentric or polycentric, are discussed. As far as pediatric tumors are concerned post-surgical adjuvant chemotherapy was proved to play a useful role in prolonging the disease-free survival in Wilms tumor, rhabdomyosarcoma, Ewing sarcoma. Results obtained in the treatment of medulloblastoma and osteogenic sarcoma need further investigations. In adult neoplasms the most important results with combined modality approach are presently being obtained in breast cancer and probably in melanoma. No consistent improvement by adjuvant chemotherapy has been observed in colorectal cancer.

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.

Ewing's sarcoma: an approach to radiological diagnosis.

All the pertinent radiographs of 83 patients with histologically proven Ewing's sarcoma were reviewed. Forty-nine patients were in the pediatric age group, and 34 were adults. The mean age, the symptoms and time from symptoms to diagnosis were evaluated in the 2 groups. The site of primary involvement was in 54% the long bones, 35% the flat bones, 8% the small bones and 3% extraosseous. For the primary site we considered the diagnostic results of the standard radiographic investigations and in some cases the usefulness of angiography, xeroradiography and telethermography. At presentation we also evaluated the possible diffusion of the disease with standard radiographic surveys (chest and skeletal, including limbs) and with foot lymphography in selected cases. In this way, 57 patients (69%) were considered to have localized disease. In this group, we also considered the value of the periodic radiographic follow-up, which enabled us to disclose the appearance of metastases (chest 64%, bone 54%, lymph nodes 11%) in 28 cases (49%). Finally, we made a comparison of the different radiologic and epidemiologic findings between children and adults.

Restatement of lymphography in childhood: experience with 413 consecutive patients in ten years.

From January 1969 to June 1978, 413 children under 15 years of age underwent lymphography at the Istituto Nazionale Tumori of 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, the 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 a recurrent tumor.

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).

Malignant ovarian neoplasms in childhood.

From 1962 to 1976, 15 children up to the age of 15 years with malignant neoplasms of the ovary were observed at the Istituto Nazionale Tumori of Milan. 13 patients had a germ cell tumor and 2 a stromal tumor. Natural history and treatment results are reported. Out of 7 patients with dysgerminoma, 3 at stage IA, 2 at stage III retroperitoneal and 1 with recurrent disease are alive and disease free 38+, 20+, 36+, 16+, 23+, 156+ months after the histologic diagnosis; the last case with stage III peritoneal disease died 2 months after the diagnosis. Four children had immature malignant teratoma: 2 patients are alive and disease free 19+ and 51+ months, 1 is alive with disease 20+ months and 1 died 16 months after histologic diagnosis. Two patients with extra-embryonal teratoma died 7 and 12 months after diagnosis. One patient, treated by surgery plus chemotherapy for granulosa cell tumor at stage III, is alive 43+ months later. The child with arrhenoblastoma at stage III treated by surgery plus radiochemotherapy died 6 months after diagnosis. Through a close scrutiny of the literature and by drawing on experience gained in the treatment of the same tumors in adults, a rational approach to the diagnosis and treatment of each childhood ovarian tumor histotype is worked out.
