A new therapy schedule for pediatric non-Hodgkin lymphoma toxicity and preliminary results

A pilot study of the toxicity and efficacy of a new treatment schedule for childhood non-Hodgkin's lymphoma was conducted by members of the Children's Cancer Study Group (CCSG) prior to its use in a randomized phase III trial. Chemotherapeutic agents used were cyclophosphamide (CPM), vincristine (VCR), and prednisone, together with intravenous (IV) and intrathecal methotrexate (IT MTX). Radiation therapy was also employed. From September 1976 to April 1977, 27 eligible, newly diagnosed patients with non-Hodgkin's lymphoma were entered onto this pilot study. Toxicity was acceptable with minor adjustments in dosage and timing of the myelosuppressive agents. Fourteen of the 22 patients entered onto maintenance remain entirely disease-free, and all have completed the prescribed course of chemotherapy. None of the 12 patients characterized as having a “favorable” prognosis has relapsed, with a median follow-up of 27 months from on study.     

Hodgkin's disease and non-Hodgkin's lymphoma in children and young adults: A clinicopathologic study of 127 cases

One hundred twenty-seven cases of non-Hodgkin's lymphoma and Hodgkin's disease in children and young adults at the University of Wisconsin Hospital between 1969 and 1980 have been reviewed. Nodular sclerosing was the most frequent histologic type in patients with Hodgkin's disease. Malignant lymphoblastic lymphoma (MLLB) was the most common type of non-Hodgkin's lymphoma. The relationship of the histological pattern to age and sex as well as clinical behavior and survival are discussed.     

Primary lymphoma of the pericardium: Report on a „Cured”︁ case and review of the literature

This report describes a 62-year-old man with a primary diffuse, immunohistochemically proven B-cell lymphoma of large non-cleaved cell (centroblastic) type of the pericardium. The patient responded completely to systemic chemotherapy and remains free of disease 30 months after diagnosis. The use of non-cardiotoxic drugs in divided doses as initial treatment is emphasized. In addition, the authors reviewed the literature of the last decade regarding the management and outcome of patients with primary cardiac lymphomas. © 1994 Wiley-Liss, Inc.     

Non-hodgkin's lymphoma in children: Results of treatment with the modified LSA2-L2 protocol

From June 1976 to May 1980, 25 previously untreated children with non-Hodgkin's lymphoma (NHL) were studied and treated with a protocol modified from the one (LSA₂L₂) proposed by Wollner [8]. Stage III and IV had, in addition, prophylactic treatment of the central nervous system (CNS) with cranial irradiation (2,400 rad plus intrathecal metho-trexate). The complete remission rate is 96%. Of these patients, 76% are disease free surviving after a median observation time of nearly two years. The disease-free actuarial survival is 100% for 6 children with Stage I-II disease and 68% for 19 Stage III-IV children after median observation times respectively of 25 + and 19 + months. None of the 19 high-risk patients developed CNS disease after prophylactic treatment. Mediastinal involvement and leukemic conversion at diagnosis were not unfavorable prognostic factors, but primary skeletal or subcutaneous disease and Burkitt-type histology were ominous features in patients treated by this regimen. It is concluded that good results are obtained when an aggressive multimodal and multiple drug regimen like the LSA₂-L₂ is coupled with CNS prophylaxis and is used assiduously to maintain complete remission during the first 12 months of treatment.     

Treatment of an aggressive non-Hodgkin's lymphoma during pregnancy with MACOP-B chemotherapy

Non-Hodgkin's lymphoma occurring during pregnancy is a rare event. A young woman at 18 weeks gestation with twins presented with a B-cell immunoblastic lymphoma. Combination chemotherapy with methotrexate, DO xorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOP-B) was instituted after limited staging. There was excellent response and the 12 weekly chemotherapy protocol was completed in 13 weeks. Twin male infants were born at 28 weeks gestation by cesarean section for premature labor. There was no evidence of any congenital malformations or hematologic suppressions. We believe this to be the first report of aggressive weekly chemotherapy during pregnancy; this approach to treatment in aggressive non-Hodgkin's lymphoma is both efficacious and safe.     

Prostatic non-Hodgkin's lymphoma causing acute urinary retention in childhood

An 8-year-old boy presented with dysuria and acute retention of urine. Rectal examination showed a hard mass arising from the prostate. CT scan of the pelvis confirmed the presence of a large prostatic tumor causing bladder outflow obstruction. A provisional diagnosis of pelvic sarcoma was initially made. Biopsy of the tumor mass however, revealed non-Hodgkin's lymphoma of T-cell type. The tumor showed very good response to chemotherapy and the urinary obstruction significantly improved with a week after starting therapy. © 1995 Wiley-Liss, Inc.     

Primary skeletal non-Hodgkin's lymphoma in the pediatric age group

The authors discuss rare primary skeletal non-Hodgkin's lymphoma in 16 patients treated from 1973 to 1989. The symptoms of these patients related to bone lesions in 95% of the cases. These bone lesions were monostotic or polyostotic, with or without regional and distant metastases. The locations of these lesions were long bones in 13 patients, pelvic bones in seven patients, and skull and vertebral bodies in two patients. The anatomical locations of these lesions in the bones were diaphysis alone in one patient, epiphysis in two patients, metaphysis in three patients, and a combination of diaphyseal, epiphyseal, and metaphyseal lesions in seven patients. Extraskeletal involvement was present in nine patients; extraskeletal sites included regional or distant lymph node involvement in seven cases, the mediastinum in two, lung nodules in two patients, the skin and subcutaneous regions in four patients; bone marrow in three patients, and peripheral nervous system (PNS) in one patient. Two patients had stage I disease, three had stage II disease, eight had stage III disease, and three had stage IV disease. The majority of patients had large noncleaved cell diffuse lymphomas or DHL by Rappaport classification. All patients were treated with the LSA₂-L₂ protocol; six patients received radiation therapy to the affected bone, and ten patients received no radiation therapy. Three patients failed on treatment within the first 4 months of therapy. Two patients developed a second tumor, one in the radiation therapy field and the other in a patient who received no radiation therapy. Eleven patients are alive without evidence of disease, with a median observation time of 6.5 years. The event-free survival for the 16 patients receiving LSA₂-L₂ was 73%, and the lymphoma-free survival was 81%. Extension of disease to multiple sites or location of the primary site was not of prognostic significance, but the finding of central nervous system (CNS), PNS, or bone marrow disease at diagnosis was. Whether the skeletal lesions were uni- or multifocal, with regional or distant metastases, the prognosis for lymphoma-free survival was good. The role of radiation therapy for all patients and intensive treatment for earlystage disease is discussed. The authors conclude that chemotherapy is the most important modality of treatment for any stage, histology, or location of the tumor. This chemotherapy shou ld include drugs that have been shown to be effective in the treatment of pediatric lymphoma, such as cyclophosphamide, cytosine arabinoside, vincristine, methotrexate, and daunomycin, in dosages sufficient to produce marrow suppression and early recovery, allowing for continuous or intermittent therapy. Radiation therapy should be used if there is no response or progression of disease (demonstrated either clinically or by scans, confirmed by a biopsy) within the first few months of treatment. © 1992 Wiley-Liss, Inc.     

Secondary malignancies in a child with Hodgkin's disease: Peripheral T-cell lymphoma and myelodysplastic syndrome evolving into acute nonlymphoblastic leukaemia

Hodgkin's disease (HD) has been linked to an increased risk of second malignant neoplasms (SMN), especially non-Hodgkin's lymphoma (NHL) and acute nonlymphoblastic leukaemia (ANLL). The mutagenic property of cytotoxic therapy as well as defective immunity have been implicated as playing a major role in the development of SMN in patients previously treated for HD. We report a case of a 14-year-old girl with HD who developed two different second malignancies within a latent period of 28 months following HD diagnosis. The patient presented initially with bilateral cervical and supraclavicular as well as mediastinal and paraaortic lymphadenopathy. She was staged as IIIA, nodular sclerosing type HD, and was given eight alternative cycles of MOPP-ABVD followed by “mantle” field radiotherapy to a total dose of 3.3 Gy plus 0.4 Gy to the upper mediastinum. Within 8 months following the completion of therapy, a period of myelodysplasia and progressive severe immune deficiency, considered as a result of initial treatment, occurred. Eighteen months after HD diagnosis while the patient was continuously neutropenic and heavily immunocompromised, a peripheral T-cell lymphoma of the angiocentric immunoproliferative lesion type (AIL) Grade III, appeared in both lungs within and beyond the radiation field, with no evidence of HD in biopsy specimens. After institution of a new chemotherapy regimen. (L17M), a satisfactory response regarding NHL lesions was noted. However, 10 months later the myelodysplastic syndrome (MDS) accompanied by complex chromosomal abnormalities evoluted to frank ANLL with a rapid fatal course. This case supports the hypothesis that combined modality treatment accompanied by severe immunodeficiency may result in the development of multiple second malignancies even within a very short latent period, especially in a subgroup of HD patients who may be at particularly increased risk for second cancers. © 1996 Wiley-Liss, Inc.     

Cavernous transformation of the portal vein in a child with non-Hodgkin's lymphoma

We present an 11 year old boy who developed collateral vessels in the portal hepatis with non-visualization of the portal vein 9 months after treatment for large cell lymphoma. This “cavernous transformation of the portal vein” may lead to varices with subsequent gastrointestinal hemorrhage. Med. Pediatr. Oncol. 29:143–145, 1997. © 1997 Wiley-Liss, Inc.

Severe humoral hypercalcemia in primary isolated non-Hodgkin's lymphoma of the heart

The etiology of hypercalcemia was investigated in a patient with primary isolated non-Hodgkin's lymphoma of the heart. There was no evidence of bone involvement, and parathyroid hormone and calciterol levels were suppressed. Plasma parathyroid-hormone-related protein (PTHrP 1–86) detected by immunoradiometric assay was increased (15 pmol/l compared with < 0.3 pmol/l in a control). We demonstrated that PTHrP was the humoral mediator of severe hypercalcemia in our patient. Med. Pediatr. Oncol. 28:183–186 © 1997 Wiley-Liss, Inc.     

Hodgkin's disease in children

From 1921 to 1973, 106 children with Hodgkin's disease under the age of 17 years were seen at Roswell Park Memorial Institute and were analyzed retrospectively. Evaluation was separated into three eras: 1921–1949 (early era), 1950–1964 (middle era), and 1965–1973 (recent era). In the early era, suboptimal radiation therapy was employed. In the middle era, radiation therapy techniques were improved, and single-agent chemotherapy was introduced. In the recent era, multiagent chemotherapy routines were frequently used; aggressive external megavoltage radiation therapy became routine in conjunction with improvement in staging procedures. The best survival was observed in the recent era where five-year survival of 96% was noted in early stage disease. Favorable prognostic features included: younger age group (5–9 years), female sex, lymphocytic predominant histology, early stage disease, and complete response to therapy. Nodular sclerosing and mixed cell types had an equal prognosis. The concept of involved area radiotherapy along with combination chemotherapy appears a reasonable approach in children and should be tested in a randomized study against more extensive radiotherapy techniques in early stage disease.     

Central nervous system involvement at diagnosis in a case of pediatric CD30+ anaplastic large cell lymphoma

Central nervous system (CNS) involvement in Ki-1/CD30 lymphoma is extremely rare, in contrast to the frequent involvement in other types of pediatric non-Hodgkin's lymphoma. No mechanism has yet been proposed to explain the sparing of the blood brain barrier in Ki-1/lymphoma. We present a 2-year-old boy who was admitted to the Department of Pediatric Hemato-Oncology due to lethargy, progressive breathing difficulties, massive diffuse lymphadenopathy, hepatosplenomegaly, and ichthyosis-like skin involvement with epidermolysis. A lymph node biopsy was compatible with Ki-1/CD30 anaplastic large cell lymphoma (ALCL). Bone marrow aspirate and biopsy demonstrated reactive hyperplasia. Cytogenetic analysis displayed hyperdiploid cells with 1p(−) in most cells. Cerebrospinal fluid examination showed pleocytosis with CD30+ cells. Possible mechanisms which could enable CNS involvement in this unusual case are discussed. Med. Pediatr. Oncol. 28:132–135 © 1997 Wiley-Liss, Inc.     

Fatal Encephalopathy with Ifosfamide/Mesna

A 7-year-old boy developed primary non-Hodgkin's lymphoma (NHL) localized to the thyroid gland and was treated with combination chemotherapy alone. He has been continuously disease-free for 5 years since diagnosis, and is probably cured, without evidence of hypothyroidism or other unwanted late sequelae of external beam irradiation. Chemotherapy, alone, should be considered for the treatment of most, if not all, cases of localized NHL in childhood.     

Ocular sequelae of multimodal therapy of hematologic malignancies in children

We retrospectively analyzed the ocular findings after polychemotherapy including intrathecal methotrexate, systemic corticosteroids, and prophylactic cranial irradiation in children with acute lymphoblastic leukemia (n = 16) and non-Hodgkin's lymphoma (n = 2). After a median surveillance time of 4.1 years, asymptomatic ocular abnormalities were observed in 83% of the patients: 7/18 had a decreased tear formation, 5/17 had an opacity of the vitreous body, and 13/18 had an opacity of the lens. It was not possible to determine retrospectively which therapy caused a particular effect. A comparison of the 2 irradiation techniques (with and without blocking of the lacrimal glands) showed that in 5/7 children who developed a reduced eye secretion, the lacrimal glands are within the treatment volume. Therefore, the reduced eye secretion is most likely radiation-induced. Whereas the opacities of the vitreous body were caused by thrombopenia and bleeding during the course of disease, corticoid therapy might have contributed to the lens opacities. © 1994 Wiley-Liss, Inc.     

Epstein-Barr virus infection,Hodgkin's disease,non-Hodgkin's lymphoma,and reactive follicular hyperplasia in Japanese children: Evaluation of paraffin-embedded specimens using polymerase chain reaction and immunohistochemistry

Epstein-Barr virus (EBV) infections are common in Japanese children, with infections by EBV type 1. The relationships between EBV infection and lymphadenopathies in Hodgkin's disease (HD), non-Hodgkin's lymphomas (NHL), reactive follicular hyperplasia (RFH), and infectious mononucleosis (IM) in 37 Japanese children were evaluated. Formalin-fixed, paraffin-embedded lymph node specimens that were obtained at surgical resection or biopsy were evaluated for the presence of EBV DNA and the latent membrane protein-1 (LMP-1) using polymerase chain reaction (PCR) and immunohistochemical staining. The PCR detected EBV DNA in nine of 13 (69.2%) patients with RFH, including a case of IM, all three (100%) patients with HD, and one of 21 (4.8%) patients with NHL. All EBV-positive samples contained EBV type 1. Reed-Sternberg's cells in HD were immunohistochemically positive for LMP-1, whereas all cases of RFH and NHL were negative for LMP-1. Results suggest that EBV infection may be related to HD. Although no proof exists that EBV infection contributes to the transformation of cells, thus causing RFH or NHL, the present authors suggest that the EBV-positive cases in Japanese children demonstrate a relationship between the clinical and histopathological features of the lymphadenopathy and EBV-type 1 infection.     

Consecutive glioblastoma and B cell non-Hodgkin's lymphoma in a young child with von recklinghausen's neurofibromatosis

A young child with neurofibromatosis type 1 (NF1) is reported who developed two primary malignancies: a glioblastoma, followed 6 months later by an abdominal B cell non-Hodgkin's lymphoma. The child is now 4.5 years off treatment and disease free, but has developed progressive and severe psychomotor retardation as sequelae. The NF1 gene is known to act as a tumor suppressor gene. The possible mechanisms leading to the occurrence of a second primary tumor in this child are discussed. © 1995 Wiley-Liss, Inc.
