Hodgkin's disease in children: Treatment with MOPP and low-dose,extended field irradiation without laparotomy late results and toxicity

The 10 year results of a trial of bimodal treatment of Hodgkin's disease in children with 6 cycles of MOPP and low-dose extended field irradiation, without staging laparotomy, were for 57 children in all stages as follows: survival 85%, relapse-free survival 80%, and survival-free of second relapse 86%. There were three fatal toxic events, two due to viral infection and one to a second malignant tumor (NHL). Three other patients developed a second malignant tumour, and one developed a thyroid adenoma. No patient developed acute leukemia. These results are compared with the results of treatment of surgically staged children by extended field irradiation alone, with bimodal treatment reserved for relapse or advanced disease at diagnosis. Initial bimodal treatment improved the overall 10 year survival free from a second relapse rate by 20% (86% vs. 66%). No major difference in treatment toxicity between these two groups has emerged during the first 10 years of follow-up. We conclude that, except for favourable CS-1 presentations, children with Hodgkin's disease confined to the lymphatic system should be given bimodal treatment, but that the least morbid effective combination remains to be determined.     

Management of childhood lymphomas—Hodgkin's disease and non-Hodgkin's lymphomas

Hodgkin's disease can be cured in greater than 70% of the children diagnosed. Overall 5-year survival rates now approach 90% and approximotely 80% for 10-year survival. Combination chemotherapy along with irradiation has decreased the relapse rate in all stages of Hodgkin's disease. Intensive chemotherapy and irradiation therapy is associated with long-term complications including development of second malignant tumors. Optimum therapy is the minimum therapy associated with uncomplicated care. In 80 to 90% of children with non-Hodgkin's lymphoma the disease is widerspread when obvious clinically at diagnosis, and the first site of relapse is commonly the bone marrow or central nervous system (CNS). Combined chemotherapy, irradiation and CNS prophylaxis has resulted in 50% to 80% 3-year, disease-free survival. Patients with mediast'nal or extensive intrabdominal disease have a poor prognosis.     

Morbus Hodgkin as a second malignancy in acute lymphoblastic leukaemia (author's transl)]

19 months after the clinical manifestation of acute lymphoblastic leukaemia, Hodgkin's disease, stage Ia, of the cervical lymphnodes developed in a 10 year old girl during continuous complete remission of leukaemia under chemotherapy. After a regional irradiation and after completing the antileukamic therapy the patient is at present off therapy, healthy and without signs of relapse of both malignant systemic diseases. The coincidence of acute lymphoblastic leukaemia in children with other malignant neoplasias is rare. The expected frequency of second malignancies and the theories concerning oncogenesis are shortly reviewed.     

Second malignant tumours in childhood Hodgkin's disease

This study was undertaken to determine the treatment-specific incidence of second malignant tumours (SMT) in childhood Hodgkin's disease. The institutional databases at The Hospital for Sick Children, the Princess Margaret Hospital, and the Toronto-Bayview Regional Cancer Centre were reviewed for the years 1958–1993. Three hundred and forty-three consecutive newly diagnosed children were evaluated. The overall 30 year cumulative SMT incidence was 31%. The 20 year SMT incidence was greater for patients who relapsed (n = 129), 27%, compared with patients who remained relapse free (n = 214), 13%. For patients with stage 1–3B disease who remained relapse free, the 10 year SMT rate was 7% for patients who were surgically staged and treated with extended field radiation treatment (EF RT) (35 G), compared with 3% in clinically staged patients treated with MOPP (six cycles) and EF RT (25–30 G). To date there is no significant difference in the oncogenicity of these treatment protocols. However, EF RT alone was less effective in disease control. For stages 1–3B, 62% of patients relapsed after EF RT alone compared with 18% after bimodal treatment. Therefore treatment intensification due to relapse was more frequent in the former group. The overall 10 year SMT incidence for patients treated with these protocols was 11% and 3%, respectively. The 20 year SMT incidence following EF RT alone was 24%. We conclude that SMTs were a common late complication in childhood Hodgkin's disease and are a limiting factor in the achievement of cure. The incidence of SMTs was increased in children who required retreatment and was minimal in children who remained in a first complete remission. Therefore the initial treatment strategy in childhood Hodgkin's disease must be to minimize the risk of relapse, in order to avoid the morbidity and mortality associated with both relapse and SMT induction, and to achieve this objective with a primary treatment protocol of low oncogenicity. © 1996 Wiley-Liss, Inc.     

Bone marrow transplantation improves survival for acute lymphoblastic leukemia in relapse: a preliminary report

Acute lymphoblastic leukemia of childhood is the most common malignant disease in children greater than 1 year of age. Chemotherapy has improved the survival of children with this disorder. More than 95% of children will achieve a remission with chemotherapy. However, 30% of children with acute lymphoblastic leukemia who achieved a remission will have a relapse sometime after successful remission-inducing chemotherapy. Although a second remission can be induced in most of these children, in 10-40% a remission cannot be induced or they relapse shortly thereafter and develop refractory leukemia. We present in this preliminary report the early results of therapy for refractory leukemia with an intensive preparative regimen for bone marrow transplantation including etoposide, cytosine arabinoside, cyclophosphamide, and fractionated total body irradiation. Transplantation was done in twenty-three patients with refractory leukemia. Projected survival at 917 days after transplantation in these patients is 43.4% +/- 11%. The survival of these patients so far is similar to the survival of children with acute lymphoblastic leukemia transplanted in second remission. All patients treated with this regimen who had transplantation in relapse were free of leukemia 27 days after transplantation. The results of this preliminary report suggest that an intensive preparative regimen can improve the outlook of refractory leukemia and may rescue some patients who otherwise would have died of their disease.     

Results of a changing treatment philosophy for children with stage I Hodgkin's disease: a 35-year experience

Over the last four decades, significant changes have occurred in the management of childhood stage I Hodgkin's disease. Between 1949 and 1984, 50 children, ages 4 to 16 years, were treated for stage I Hodgkin's disease at The University of Texas M. D. Anderson Cancer Center. Nineteen children had clinically staged (CS) disease. Thirty-one patients were pathologically staged (PS). Thirty-four children were treated with radiotherapy only, 12 were treated with both radiotherapy and chemotherapy, and 3 patients were treated with combination chemotherapy alone. All patients were followed from 32 to 311 months (median 170 months). Five-, 10-, and 15-year actuarial survival rates for all patients were 94, 89, and 84%, respectively. The corresponding freedom from relapse (FFR) rates were 76, 69, and 69% respectively. The 10-year actuarial survival and FFR rates for CS patients were 79 and 42%. The corresponding rates for PS patients were 97 and 86%. In patients with PSI disease, actuarial 10-year FFR rates of 100% were obtained either with regional radiotherapy alone or with combination chemotherapy and involved field radiotherapy. The following delayed adverse effects of treatment were observed: growth abnormalities in 17, aspermia in 3, thyroid abnormalities in 11 (two carcinomas), and second malignancies beyond the radiotherapy fields in 2. We conclude with a recommendation of combined chemotherapy and involved field radiation for children who have not fulfilled their growth potential, to achieve high cure rates, while minimizing morbidity.     

Hodgkin's disease. Treatment of the young child.

Age of a patient when afflicted with Hodgkin's disease is an important prognostic factor. Although there are histologic and stage differences as a function of age, the younger a patient is when diagnosed, the better the cure rate. Youngsters less than age 10 years have a freedom from relapse of 80% at 26 years follow-up examination; adolescents in the 11 to 16 age group have a freedom from relapse or 74%; and adults aged 17 years or older have a freedom from relapse of 64%. These differences translate into significant survival differences as well, with children aged 10 years or younger and those aged 11 to 16 years having a 26-year survival of 74%, as compared to adults, who have a 37% survival (P = 0.003). These differences remain significant when comparing those with stage I and II disease, as opposed to those with advanced stage III and IV disease. Children present the greatest challenges with respect to staging and treatment. The older child with localized disease can be managed appropriately as an adult. However, for the younger child the use of low-dose radiation and multiagent chemotherapy is widely accepted. Using this approach, survival rates of 85% or greater are reported from many large institutional and cooperative group experiences. The goals of treatment today are cure of disease, with maximal quality of life and minimal complications from the treatment. The late effects of greatest importance to the youngest children are skeletal and bone growth abnormalities, sterility, and malignant tumor induction. Treatment programs today should be directed towards refining therapy to minimize sequelae while maximizing quality of life. These goals are best achieved when children are managed in regional centers with demonstrated expertise in the management of children with Hodgkin's disease. Whereas cure can be achieved in a large majority of children diagnosed with Hodgkin's disease, our challenge is cure, with the least sequelae and the greatest quality of life. "Children are not simply micro-adults, but have their own specific problems."     

Chemotherapy and irradiation in childhood Hodgkin's disease.

Eighty children aged less than 16 years with newly diagnosed Hodgkin''s disease were treated between 1974 and 1982. Complete remission occurred in 95%, with actuarial five year overall survival of 94%, and relapse free survival of 82%: median follow up was 4.8 years. Sixty one children were staged clinically while 19 had staging laparotomies before treatment. Most received combined modality treatment with Ch1VPP chemotherapy (chlorambucil, vinblastine, procarbazine, and prednisolone) followed by irradiation of initial bulk disease. Nodular sclerosis predominated in both sexes, accounting for 60% of the total. Girls with stage IV disease, nodal sclerosis histology, and bulky mediastinal masses had a relatively poor prognosis. Ten children have relapsed, and three prolonged (6 to 7 years) second remissions have been observed. Four died of disease, and one from infection. Clinical staging, avoiding splenectomy, reduced the risk of serious infections. Our current policy is to treat stage IA disease with local irradiation and all other stages with chemotherapy, adding irradiation for bulky mediastinal disease.     

Thyroid cancer following radiotherapy for Hodgkin's disease: a case report and review of the literature

Improved survival resulting from advances in therapy in patients with Hodgkin's disease is associated with long-term morbidity, including the potential for the development of a second solid malignancy. We report a 44-year-old man with an unusually aggressive course of thyroid carcinoma 15 years after treatment for Hodgkin's disease. In a review of the English-language literature, we found 21 cases of thyroid cancer following radiotherapy for Hodgkin's disease, with latency periods ranging from 6 to 48 years. The development of secondary thyroid cancer after high-dose neck irradiation may be related to hypothyroidism, itself a complication of radiotherapy. Thyroid function should be measured at least once a year in all patients given neck irradiation, with initiation of thyroid hormone replacement if there is evidence of sustained hypothyroidism.     

Comprehensive treatment of advanced neuroblastoma involving autologous bone marrow transplant

Encouraging results are reported with high-dose chemotherapy and total body irradiation followed by autologous bone marrow transplantation in the treatment of advanced neuroblastoma. However, relapse remains a significant problem. We used high-dose chemotherapy, surgery, intraoperative radiation and an autologous bone marrow transplant treated in vitro to remove tumor cells followed by 13-cis-retinoic acid to treat 36 children with advanced neuroblastoma. This comprehensive treatment appears to improve the survival rate of patients with advanced neuroblastoma, including those with N-myc amplification and bony involvement. The disease-free survival rate was 66% (95% confidence interval, 49–84%) at 3 years. All patients who received 13-cis-retinoic acid developed cheilitis, but no bone marrow depression occurred in these patients. Five patients developed hemolytic uremic syndrome (HUS) post-transplant. This may have been related to the procedure used for total body irradiation. Patients who had their kidneys shielded during this procedure did not develop this syndrome. Patients who received local irradiation at the primary site showed no evidence of relapse in this region, indicating that such therapy may help to prevent a relapse. These data suggest a high rate of 3 year disease-free survival with this treatment strategy. The nonrandomized nature of the study and use of multiple modalities precludes analysis of the specific contribution of each.     

Delayed craniospinal irradiation for a first isolated central nervous relapse of acute lymphoblastic leukemia: report on 14 cases

BACKGROUND: Children developing an isolated central nervous system (CNS) relapse as first recurrence of their acute lymphoblastic leukemia (ALL) are considered to have a systemic relapse as well. They are mostly treated with intensive chemotherapy and craniospinal irradiation. In most treatment schedules, irradiation is given early after induction treatment. Because craniospinal irradiation affects a large portion of hematopoietic bone marrow systemically, treatment is often delayed owing to aplasias. Also, dose reductions are frequently needed. Children receiving simultaneously irradiation and chemotherapy are prone to (often severe) neurotoxicity. This study reports on children with a first isolated CNS relapse of their ALL receiving chemotherapy for 40 weeks. Treatment ends with the administration of irradiation given after cessation of chemotherapy. PROCEDURE: Fourteen children, with blasts and >5 cells/mm(3) in two consecutive samples of cerebrospinal fluid and a blast percentage <5% in their bone marrow were treated according to an intensive systemic and site-specific chemotherapy. Craniospinal irradiation was administered after cessation chemotherapy. RESULTS: Event-free-survival was 57% (confidence interval 35-89%), freedom from relapse was 61.5%; follow-up ranges from 2.0 to 15.1 years (median 11.7 years). One child died from septicemia during induction. Five children experienced a second relapse and died from their malignancy. Two children [with a t(9;22) or a rearranged MLL gene] relapsed prior to radiotherapy. Outcome was related to duration of first remission, age at relapse, and identification as a high-risk patient at initial diagnosis. No neurologic complications were noted during and after treatment. CONCLUSIONS: Delayed irradiation for isolated CNS relapse in children with ALL gives favorable survival rates, without significant toxicity. Neurotoxicity was absent.     

Short- and long-term results of multimodal treatment program of lymphogranulomatosis (Hodgkin's disease) in children and adolescents]

Short- and long-term results of combined treatment of 440 children and adolescents afflicted with lymphogranulomatosis (Hodgkin's disease) were traced. A group of 104 children received treatment in 1964-1973. Complete effect was attained in 72.1% of the patients (in 75 out of 104); the 5-year survival was 72.5%, the 10-year 61.1%, the 15-year 52.75%. The long-term results are described in detail. Analysis of the results allowed basing the necessity of the three-stage combined chemoradiation therapy in children with lymphogranulomatosis. In 1976-1980, the treatment according to the first combined program was provided to 193 children and adolescents aged 2.5 to 16 years suffering from lymphogranulomatosis. In 1979-1983, the treatment according to the second combined program was provided to 143 children and adolescents aged 3 to 15 years suffering from the same disease. In patients treated according to the first and second programs, the 5-year survival amounted to 81.3 and 93.3%, respectively. The total number of lethal outcomes was 20.2 and 4.2%, respectively, during the whole observation period.     

Secondary Hodgkin's disease in childhood acute lymphoblastic leukemia

Improved survival in childhood acute lymphoblastic leukemia has led to the occurrence of second malignancies in these patients. Hodgkin's disease is very rare as a second malignancy. We report three patients with acute lymphoblastic leukemia in remission who developed Hodgkin's disease. Although all had received low-dose irradiation, none received alkylating agents as part of their chemotherapy. Review of our cases and of 11 reported in the literature revealed unique aspects of this association. There was a short median interval of 19 months to the development of the second malignancy. Over one-third of the patients had uncommon sites of involvement (lung, tonsil, small bowel). The distribution of histologic subtypes was unusual, as 5 of 14 cases had lymphocyte depletion or unclassifiable Hodgkin's disease. The results of therapy were excellent. Our three patients are alive, with both malignancies in continuing remission. Two patients are off all therapy for 4 and 6 years, respectively. The third remains on antileukemic treatment. Secondary Hodgkin's disease in childhood acute lymphoblastic leukemia does not appear to have a poor prognosis and long-term survival and possible cure of both diseases may be achieved.     

Involved field (IF) irradiation with or without chemotherapy in the management of children with Hodgkin's disease

The present policy at Memorial Sloan Kettering Cancer Center (MSKCC) of treating children with Hodgkin's disease [HD] is as follows: involved field (IF) irradiation only (3,600 rad) for Stages IA and IIA; IF irradiation (2,400 or 2,000 rad) combined with multidrug chemotherapy (MDP) protocol for all other stages. A somewhat higher recurrence rate is accepted for Stages IA and IIA in view of the good salvage rate for these recurrences and in view of side effects of more aggressive types of radiation treatment. One hundred forty-two patients with HD, 2-19 years of age, were treated at MSKCC between 1970 and 1981; 98 of these were treated according to the present policy (SP group), and 44 (NP group) were treated differently. All SP patients underwent staging laparotomy. The follow-up time was 12 to 146 months with a median of 65 months; two patients were lost to follow-up. For the SP group, all stages, 10-year disease-free survival is 77%, and 10-year survival is 93%. By comparison, in the NP group 10-year disease-free survival is 64%, and 10-year survival is 80%. The disease-free survival of SP patients in Stages IA and IIA treated with IF radiation alone is 72%, and survival is 95%. The disease-free survival of SP patients in advanced stages treated with combined radiation and chemotherapy is 87%; the salvage rate of recurrent disease in these stages is poor. The survival was apparently better (P = 0.07) in the SP group as compared to the NP group. All 6 patients of the SP group who died had a nodular sclerosing type of HD. None of the patients in the SP group have developed secondary malignancies, and no severe bone growth retardations or late effects to other organs were observed. In our opinion, IF irradiation alone might at present be suitable treatment for children in Stages IA and IIA of Hodgkin's disease, and addition of IF radiation with low doses of MPD improves the survival of patients in advanced stages.     

Hodgkin's disease in Turkish children: clinical characteristics and treatment results of 210 patients

Although Hodgkin's disease (HD) is one of the common malignancies in childhood, there is limited information from developing countries in English literature. The aim of this study is to give epidemiologic features and treatment results of 210 previously untreated children with HD from a developing country. Between 1 June 1984 and 31 December 1992, all children seen who were younger than 18 years old with newly diagnosed, untreated, biopsy-proven Hodgkin's disease were included in this study. A clinical staging system was used to determine the dissemination of the disease. While patients with stage I-II disease received canape treatment protocol (three cycles COPP \[cyclophosphamide, vincristine, procarbazine, prednisolone] or ABVD \[doxorubicin, bleomycine, vinblastine, dacarbazine] plus low-dose involved-field radiotherapy), patients with stage III-IV disease were treated by sandwich protocol (six cycles COPP plus low-dose involved-field radiotherapy). A total of 210 patients with a median age of 8 years were eligible for this study. Male to female ratio was 3:1 and 37 (17.6%) were less than 5 years of age. The major histologic subtype was mixed cellularity (69.6%). Overall survival rates were 91.5 and 87.7%, and event-free survival rates were 71.5 and 70.5% at 5 and 10 years, respectively. No secondary malignancy has been observed so far. The prevalance of Hodgkin's disease in young children is higher and the distribution of histologic subtypes is also different from many Western countries. Canape and sandwich treatment protocols could be used safely in clinically staged childhood HD with tolerable toxicity.     

Relapse after first cessation of therapy in childhood acute lymphoblastic leukemia: A 10-year follow-up study

The outcome of 171 children with ALL who relapsed for the first time after elective cessation of therapy (1–86 mo) and followed over 10 years (median 60 mo; range 1–232 mo) has been evaluated. One hundred and three patients relapsed in the bone marrow (BM), 29 in the testis (T), 21 in the central nervous system (CNS), 14 in the BM plus another site and 4 in other sites. Second remission was achieved in 97% of patients (97% BM, 100% T, 90% CNS, respectively) with reinduction schedules including three or more drugs. All but 4 out of 100 patients who relapsed in the BM received cranial reprophylaxis with intrathecal CT alone or CT plus radiotherapy. Seven patients in second CR underwent allogeneic bone marrow transplantation from an HLA matched sibling. The overall survival was 34% and disease-free survival (DFS) probability at 100 years was 22%. A second relapse was observed in 73% of patients. Forty children are alive in second continuous remission and 24 are alive after a second or subsequent relapse. Patients with isolated T relapse showed a significant better outcome than those with BM or CNS involvement. Most patients (62%) with isolated BM relapse showed a further disease recurrence in BM, and DFS was shorter when relapse occurred within 12 months from off-therapy. Eighty-two patients in second CR stopped the treatment a second time and showed a survival and DFS probabilities, respectively, of 69% and 43%. Thus, children with ALL who relapse after cessation of therapy still have a high risk of further late relapses and should be treated with intensive chemotherapy and CNS reprophylaxis. BMT must be considered for all patients relapsing in the BM within 12 months from off-therapy. © 1995 Wiley-Liss, Inc.     

Long-term control of central nervous system leukaemia.

Seventy-four children with acute lymphoblastic leukaemia had one or more episodes of central nervous system (CNS) leukaemia. 5 children had CNS involvement at diagnosis; 4 survived for less than one year. In 35 children who had not had a previous bone marrow relapse on treatment and who received combination chemotherapy, the median duration of haematological remission from the time of first CNS relapse was almost 3 years. 5 children received full dose (2400 rads) craniospinal irradiation after their first CNS relapse; 4 have remained in CNS and haematological remission for 2 1/2 years or more. 18 children who had a CNS relapse after irradiation received 4-weekly intrathecal methotrexate; in 8 children this was given via an intraventricular reservoir. The median duration of CNS remission in children receiving intrathecal methotrexate was 2 years. Systemic and intrathecal treatment was stopped in 7 children after 2 1/2 years in continuous remission and in 2 children after 2 years. 4 of these 9 children remain in remission at intervals from 41 to 69 weeks off treatment but one is severely retarded. These results show that CNS disease is compatible with prolonged survival, but illustrate the difficulties of eradicating established CNS leukaemia.     

Hodgkin's disease in children: Involvement of lung and pleura

In 160 children with Hodgkin's disease, lung involvement was studied. In 14.4%, lung lesions were diagnosed at the first admission and an additional 7.5% of patients developed lung lesions in the course of the disease. As a rule lung involvement was observed in advanced disease. It has been stated that there is no particular difference in the response to treatment in any particular type of lesion, spread either by contiguity or dissemination. Of all methods of treatment, combination chemotherapy (MOPP programme) showed the best results. In our series of children it was not possible to show any advantage to favour irradiation as against combination chemotherapy in the treatment of lung lesions.     

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.     

HERPES ZOSTER AND VARICELLA IN CHILDREN WITH HODGKIN'S DISEASE

ABSTRACT. Thirty-nine episodes of herpes zoster and varicella in 94 children with Hodgkin's disease were studied to determine the incidence and complications of these infections and their effect on the prognosis of Hodgkin's disease in children under multimodal treatment. Twenty-nine children (31%) developed herpes zoster and seven (7%) had varicella. Three children had herpes zoster on two occasions. All children with varicella had uncomplicated infections. One patient died and three had visceral complications secondary to herpes zoster infections. Disseminated herpes zoster in nine children (10%) was more often associated with recurrent or active Hodgkin's disease and led to more complications than localized herpes zoster. Although varicella-zoster infection does not impair the prognosis of Hodgkin's disease, it is a potentially fatal infection and an affected child deserves vigorous treatment and support.
