A 12-year-old girl with acute promyelocytic leukemia has been treated with conventional chemotherapy. The patient remained in complete remission for a year when the first bone marrow relapse occurred. Since reinduction chemotherapy was rejected by the parents, an alternative treatment with oral all-trans retinoic acid was administered. A second complete remission was achieved within 100 days. After 14 months a second bone marrow relapse occurred. AM-trans retinoic acid and the combination with interferon-a failed. 相似文献

Osseous relapse, as distinct from bone marrow relapse, is possible during treatment of childhood leukemia. The authors have observed an isolated leukemic bone lesion in an 8-year-old boy in complete bone marrow remission after a second full course of chemotherapy for a testicular leukemic localization. The radiological signs in our case are peculiar because a small bone of the foot (right talus) showed an increased density instead of rarefaction; histological examination demonstrated leukemic bone infiltration. Local radiotherapy (2400 cGy) was given and multidmg induction and maintenance for one year. Two years after the histological diagnosis the child is still in complete remission. This observation suggests that structural bone may be a sancturay site for leukemic cells. 相似文献

Continuation therapy using intermittent chemotherapy and BCG inoculation was commenced in 28 children with acute lymphocytic leukemia (ALL) immediately after remission induction and "CNS prophylaxis." At a median followup time of 17 months, 71% remain in total remission and 86% in bone marrow remission. Complications of the therapy were minimal. Major infections occurred on two occasions and there were no deaths in remission. Neutropenia, "minor" infections and postponement of chemotherapy occurred most often during the first three courses of treatment. There were no local or systemic BCG infections. Tuberculin sensitivity was tested in 25 patients. It was positive in 17 of 18 patients in total remission and all four patients with only CNS relapse, and was negative prior to relapse in three patients who developed bone marrow disease. 相似文献

Central nervous system (CNS) involvement is rare in acute promyelocytic leukemia (APL). The majority of CNS relapses occur in patients with hyperleukocytosis at presentation, and the optimal management of such patients is still controversial. We describe a 13-year-old boy with APL who developed an isolated CNS relapse after first-line treatment with all-trans retinoic acid and chemotherapy. A second remission was achieved with a regimen consisting of intrathecal chemotherapy, intravenous high-dose cytarabine, and oral 6-mercaptopurine. All-trans retinoic acid was avoided owing to severe complications during initial therapy. The patient remains in molecular remission at 9 months after autologous stem cell transplant. Prognostic factors of CNS relapse in children with APL are needed to define the indications for CNS prophylaxis in this group of patients. 相似文献

In the past 16 years, 2004 children with acute lymphoblastic leukemia (ALL) have been treated in the Polish Pediatric Group centers. Eight hundred and eighty-seven (44.3%) of these patients discontinued treatment after the first remission. Acute lymphoblastic leukemia relapse occurred in 180 patients (20.3%). This group was analyzed for the method of treatment and its influence on long-term survival, the time between cessation of treatment and relapse, the character and localization of relapse and later follow-up. It was shown that the patients with the best chance of a second remission are those with late testicular relapse. The most frequent and prognostically poor are bone marrow (BM) relapses which warrant intensive chemotherapy with BM transplantation. Patients with ALL relapse still have the possibility of a second remission and long-term survival. 相似文献

Childhood B-cell neoplasms account for approximately 2% of childhood acute lymphoblastic leukemia (ALL). The short but intensive chemotherapy yields a currently 75% to 85% event-free survival. The prognosis for children with relapsed disease is considered to be dismal.We report a 12-year old boy diagnosed with B-cell ALL with central nervous system (CNS) involvement. He relapsed in the bone marrow immediately after primary chemotherapy. Rituximab as a single agent achieved a complete morphologic remission. After 4 treatments with rituximab an isolated CNS relapse occurred. CNS remission was reinduced with chemotherapy and the patient received an autologous transplant with rituximab for in vivo purging. He is currently in complete clinical and molecular remission for more than 1 year. 相似文献

Leukemia cutis (LC) are not rare in acute myeloid leukaemia (AML) in children but exceptionally reveal it. Most authors think that they have poor prognosis. CASE REPORT: We report the case of an infant with isolated cutaneous involvement at the time of diagnosis of leukaemia. Bone marrow aspiration showed AML M5. The child was treated by LAME 91 protocol, arm "infant under one year of age". Complete remission, both in bone marrow and skin, was obtained after induction course. Then the patient received consolidation course and megatherapy followed by autologous bone marrow transplantation. Skin relapse occurred early. The complete remission no. 2 was not obtained by second line treatment: new LC appeared when PMN count increased more than 10(9)/l. Then, the child was treated with oral VP16 but disease progressed with more and more LC, followed by bone marrow relapse. Child's death occurred about one year after diagnosis. 相似文献

Extramedullary relapses in children with acute lymphoblastic leukemia occur most frequently in the central nervous system and in the testis. In this report, the authors describe a 16-year-old girl with an isolated renal relapse of acute lymphoblastic leukemia after a disease-free interval of 2 years and 8 months. This clinically inconspicuous renal relapse was suggested by a routine follow-up renal sonography. No evidence of disease was found in bone marrow or peripheral blood. Renal biopsy was required to establish the diagnosis. Treatment consisted of intensive chemotherapy and autologous bone marrow transplantation. The patient has been in second complete continuous remission for 7 years. The authors recommend the use of an intensive multidrug salvage regimen. 相似文献

An infant with congenital leukemia in complete remission (CR1) received an unrelated donor umbilical cord blood cell transplant from a one-HLA disparate donor. The conditioning regimen consisted of thiotepa, busulfan and cyclophosphamide. GVHD prophylaxis consisted of tacrolimus and mini-methotrexate. Engraftment occurred and a bone marrow aspirate obtained on day 28 showed 100% donor cells. The post-transplant course was complicated by skin and liver GVHD, grade III, that responded to therapy with methylprednisolone, anti-thymocyte globulin and daclizumab (Zenapax), in addition to tacrolimus. A bone marrow aspirate obtained on day 187 showed relapse, with 17% blasts. The patient was then treated for 30 days with recombinant human granulocyte-macrophage colony-stimulating factor treatment (rhGM-CSF). A bone marrow aspirate obtained 17 days after the initiation of rhGM-CSF treatment showed 2% blasts. Ascites was the predominant side-effect of the rhGM-CSF treatment. The patient remains in complete remission 24 months after relapse and 30 months after transplantation. This case documents that rhGM-CSF and withdrawal of immunosuppression can induce a durable complete remission after relapse following an unrelated donor cord blood transplant. 相似文献

Recovery from widespread bone marrow necrosis occurring after chemotherapy for adult acute monocytic leukemia. 总被引:3,自引:0,他引:3
A patient with acute monocytic leukemia who developed bone marrow necrosis following induction chemotherapy is presented. Although the bone marrow necrosis was extensive, recovery occurred, along with complete remission of leukemia. Severe bone marrow necrosis in this setting may be reversible, and continued vigorous supportive care for these patients should be strongly considered. 相似文献

EMR without BM involvement after allogeneic HSCT is extremely rare, especially in children; only a few cases have been reported. A two-yr-old boy was diagnosed with AML (M4) and underwent allogeneic HSCT in first complete remission with BM from HLA-matched unrelated donor without GVHD. Four yr later, he had a BM relapse and after induction and consolidation chemotherapy, he received a second HSCT from an unrelated donor using peripheral blood stem cells. His second post-transplant course was complicated by extensive chronic GVHD involving the skin, oral cavity, and lungs, which was treated with tacrolimus and corticosteroid. Two yr later, he noticed a mild swelling in the right cheek area. The BM showed a complete remission marrow and a soft tissue biopsy was compatible with granulocytic sarcoma. PET-CT showed multifocal bone involvements. He received chemotherapy, and the chloromas decreased in size. We report a case of diffuse EMR of AML without BM involvement after a second allogeneic HSCT. 相似文献

Twelve children with their first relapse of acute lymphoblastic leukemia who had the same initial therapy were treated on an out-patient basis. After 28 days all entered second remission. Medium remission duration was 11 months. At the end of the study seven patients were in continuous complete remission. Of the twelve children seven suffered bone marrow, two meningeal, two testicular relapses and one a combined bone marrow and meningeal relapse. Side effects were compatible with an out-patient treatment. 相似文献

An 11-year-old boy with prior bone marrow and testicular relapses of his acute lymphoblastic leukemia (ALL) developed an isolated metatarsal bone relapse during complete hematologic remission 10 months after completion of chemotherapy. Although there was no radiographic or histologic evidence of additional occult leukemia, the polymerase chain reaction (PCR) technique detected a leukemic clone in both his bone marrow and metatarsal. A literature survey revealed only 10 reported cases of isolated bone relapse occurring during complete bone marrow remission in childhood ALL. Most of these patients had prior bone marrow or extramedullary relapses. The majority experienced subsequent relapses after their isolated bone recurrence. We report a case of isolated bone recurrence, review all previously reported cases, and suggest that PCR elucidation of clonal disease may provide a better understanding of these extremely rare extramedullary events. © 1994 Wiley-Liss, Inc. 相似文献

A multicentric retrospective study on leukemic ophthalmopathy (LO) is reported. It includes 21 patients, 16 males and 5 females, with acute leukemia (AL) observed in 10 SIOP centers. LO developed in three patients at the time of diagnosis of AL; five patients were in first complete remission (three off therapy); four patients were in second or third remission; and nine were in combined relapse. Most frequent symptoms were blurred vision, photophobia, and ocular pain. Two patients with acute nonlymphoblastic leukemia died before treatment; another underwent bone marrow transplantation; one patient with B-cell acute lymphoblastic leukemia (B-ALL) treated with chemotherapy and radiotherapy died 4 months after LO; the remaining 17 children were treated according to different schedules with (10) or without (7) radiotherapy on the affected eye. Twelve patients achieved ocular remission and four of these had a second ocular relapse. Complete remission after LO treatment lasting for more than 3, 7, 24, 29 months was observed in four patients. The authors conclude that cure is possible in patients who had LO in first complete remission treated with chemotherapy and radiotherapy at high dose on the affected eye. © 1994 Wiley-Liss, Inc. 相似文献

Although the majority of children with acute lymphoblastic leukemia (ALL) can electively stop treatment after 21/2–5 years of continuous disease-free remission, 20–25% of those patients relapse after discontinuation of therapy. We treated 15 patients whose disease recurred after stopping treatment. Fourteen of them attained complete remission, but the median duration of disease-free survival was only 11 months. In this population, the site of initial relapse, bone marrow or testicle, did not influence subsequent outcome. Patients who relapsed within six months of stopping initial therapy had shorter second remissions than those who relapsed after six months. We conclude that the combination chemotherapy utilized in this study was inadequte for the control of relapsed ALL. Future programs will have to use different drug combinations or bone marrow transplantation. 相似文献

A multicentric retrospective study on leukemic ophthalmopathy (LO) is reported, including 38 patients (21 males, 17 females) with acute leukemia (AL) observed from 1976 to 1985. LO developed in four patients at the time of diagnosis of AL; ten were in first complete remission (eight off therapy), 12 in second remission, and 12 in combined relapse. The children were treated according to different schedules of systemic and intrathecal chemotherapy with or without radiotherapy (RT) of the affected eye. Ocular remission occurred in 32 of 38 patients, but with subsequent ocular relapse in six of the 32. Complete remission after LO treatment lasting for more than 24, 30, 40, and 78 months was observed in four of the ten children with isolated LO in first AL marrow remission. The authors concluded that systemic and intrathecal chemotherapy probably is associated with RT (at least 30 Gy to the affected eye). Aggressive treatment is justified because children with isolated ocular relapse can still be cured. 相似文献

The therapeutic benefit of maintenance chemotherapy beyond three years for children with acute lymphocytic leukemia (ALL) in continuous complete remission was evaluated by the investigators of Childrens Cancer Study Group (CCSG). Two hundred and twenty leukemic children in first remission for three years or longer and who had received at least three years of continuous chemotherapy were eligible. One hundred and one patients were randomized to either continue chemotherapy for an additional three years or to discontinue therapy, and 119 patients nonrandomly continued or discontinued therapy. The patients had received a variety of chemotherapy regimens. The study period extended from April 1970 until December 1977, with a median follow-up time of 25 months. Relapses occurred in 15 randomized patients (15%). Randomized patients remaining on chemotherapy experienced a statistically significant lower relapse rate than patients randomized to discontinue therapy. Also among randomized patients, bone marrow relapse was signicantly more frequent in males than in females. Considering the total patient group, age and white blood count at diagnosis had no significance in predicting relapse. Of relapse events in males, 21% were isolated testicular relapses, identifying the testicle as a major risk site in males completing three years of continuous complete remission. This study demonstrates that continuing chemotherapy beyond three years results in a significant prolongation of remission in males, although the eventual survival outcome for later discontinuance of therapy will require longer follow-up. 相似文献
