Myeloablative treatment intensification in 25 patients diagnosed when older than 12 months of age with stage IV neuroblastoma included sequential delivery of cisplatin 120 mg/m2 x 1, hyperfractionated radiation (2,100 cGy) to the primary site and adjacent lymph nodes, carmustine (BCNU) 200 mg/m2 x 1, melphalan 60 mg/m2/d x 3 (n = 13) or thiotepa 300 mg/m2/d x 3. (n = 12), and etoposide (VP 16) 300 mg/m2/d x 3. Seventy-two hours after the last dose of VP 16, histologically tumor-free and 4-hydroperoxycyclophosphamide (4-HC; 100 mumol/L)-purged autologous bone marrow (ABMT) was infused. Acute toxicities included grade 3 to 4 oral mucositis, grade 1 to 2 diarrhea, and fevers. No patient required infusion of unpurged reserve autografts. At ABMT, 16 patients (group I) were progression-free 6.5 months to 14 months (median, 9 months) from diagnosis: seven remain progression-free 20 months to 46 months (median, 39 months) off therapy, six relapsed 4 months to 17 months post-ABMT, and three died of toxicity (candidiasis, metabolic derangement, and venoocclusive disease [VOD]). The event-free survival of group I patients is 44% at 24 months post-ABMT. Nine patients (group II) were in second remission at ABMT, including three who had relapsed after other transplant procedures: two are progression-free 24 months and 41 months off therapy, four relapsed 3 months to 12 months post-ABMT, and three died of toxicity (aspergillosis, hemorrhagic cystitis, VOD). Only one of 10 relapses involved a primary site, suggesting a beneficial effect of local radiation. In terms of survival or toxicity, an advantage for melphalan or thiotepa was not evident. Regimens such as this may prolong the survival of selected patients with poor-risk neuroblastoma, but concerns over late relapses and toxicity mandate continuing efforts to devise alternative, less risky, and more clearly beneficial approaches for definitive ablation of neuroblastoma.

One hundred nine newly treated patients with advanced neuroblastoma were entered in this study between January 1985 and May 1989. The eligible patients included infants younger than 12 months of age with Stage IVA disease (bone cortex, distant lymph node, and/or remote organ metastases) and patients aged 12 months or older with Stage III or IV disease (IVA plus IVB with tumor crossing the mid-line and with metastases confined to bone marrow, liver, and skin). The patients first received six cyclic course of intensive chemotherapy (regimen A1), consisting of cyclophosphamide (1200 mg/m2), vincristine (1.5 mg/m2), tetrahydropyranyl adriamycin (pyrarubicin; 40 mg/m2), and cisplatin (90 mg/m2). Original tumors and the regional lymph node metastases were removed some time during these first six cycles of chemotherapy. The patients were further divided into three groups. Patients in course 1 received alternating treatment by regimen B (cyclophosphamide and ACNU) and intensified regimen A1, and those in course 2 were treated with alternating administration of regimen C (cyclophosphamide and DTIC) and intensified A1. Patients in course 3 were treated with bone marrow transplantation (BMT) preceded by high-dose preconditioning chemotherapy. Survival rates were 77% in Stage III and 54% in Stage IV at 2 years, and 70% in Stage III and 45% in Stage IV at 3 years. The major toxicities encountered were bone marrow suppression with leukocyte counts down to 100/mm3, mild cystitis, and hearing impairment. The 2-year survival rate was 78% in 21 patients who underwent BMT when complete remission was achieved. We concluded that our intensive induction chemotherapy is of significant value in increasing the rate of complete response, and in widening the indications for and achieving improved results of treatment with BMT.

Fifty-seven patients with advanced malignant tumours were treated with ifosfamide (Holoxan) and mesna (Uromitexan) in our department from November 1979 to December 1984. This series comprised eight cases of soft tissue sarcoma, nine cases of ovarian carcinoma, five cases of non-seminomatous testicular tumour, 11 cases of bronchogenic carcinoma, three cases of renal carcinoma, seven cases of non-Hodgkin's lymphoma, two cases of skeletal fibrosarcoma, two cases of breast carcinoma, one case each of Ewing's tumour, prostatic carcinoma, seminoma, plasma cell tumour, multiple myeloma, malignant teratoma, nasopharyngeal carcinoma, Wilms's tumour, neuroblastoma and mycosis fungoides. Out of these 57 cases, 53 were evaluable. There were five complete remissions and 20 partial remissions, corresponding to a total response rate of 47%. The overall median survival time (MST) of the 53 evaluable patients was 7.5 months. The responders had a longer survival time (MST 10 months) than the non-responders (MST 4.75 months) (p greater than 0.05). Analysis of the results according to sex, age, dosage of ifosfamide and degree of histological differentiation of the tumour cells failed to show any influence of these factors on the therapeutic results. The response rate to ifosfamide found in this study might be related to the histological origin of the tumours and to whether the primary tumours had been resected. The non-seminomatous testicular tumours, non-Hodgkin's lymphomas and ovarian carcinomas showed a high response rate. The response rate was higher in the group in which the primary tumour had been resected (61%) than in the non-resected group (12%) (except the non-Hodgkin's lymphoma). The side-effects of this regimen were moderate. Dyspepsia, nausea, vomiting, myelodepression, dizziness, and alopecia were common. Cystitis could be prevented nearly completely by concomitant administration of mesna, when given correctly, for preventing side-effects of ifosfamide on the urinary system (haemorrhagic cystitis, etc.).

A rationally devised induction regimen of vincristine, Adriamycin (Adria Laboratories, Columbus, OH), and sequentially-escalated cyclophosphamide (CPM), followed by S-phase-specific agents (5-fluorouracil [5-FU]/cytosine arabinoside [ara-C]/hydroxyurea), was used in 100 patients with neuroblastoma. Of 17 patients under 1 year of age at diagnosis, complete (CR)/good partial (GPR) responses with long-term disease-free survival were achieved in 11 (85%) of 13 new patients and in two of four previously treated patients; six of the GPRs also received myeloablative therapy with autologous bone marrow rescue to consolidate remission status. The 83 patients over 1 year of age at diagnosis included three groups: (1) 36 new patients whose N4SE included maximal-dose CPM (ie, up to 140 to 160 mg/kg/course); (2) an earlier group of 18 new patients whose N4SE included moderate-dose CPM (ie, up to 80 mg/kg/course); and (3) 29 previously treated patients who all received the maximal-dose N4SE regimen. For new patients, CR/GPR rates were 72% in the maximal-dose group v 39% in the earlier moderate-dose group (P = .029). A CR/GPR rate of 41% and a partial response rate of 17% were observed for the 29 previously treated patients, all but two of whom had large tumor burdens after therapy that included moderate doses of CPM. Despite consolidation with myeloablative therapy, many responders in the three groups ultimately relapsed. The N4SE was strongly myelosuppressive, but only two patients died from associated infection. Extramedullary toxicity was limited to hemorrhagic cystitis in four of 33 CPM previously treated patients; this problem did not occur in the 67 new patients. The data indicate that the maximal-dose N4SE is an effective induction regimen for neuroblastoma, can achieve marked regressions of disease resistant to less intensive therapy, and is sparing of major body organs. This high rate of remission induction must be coupled with improvements in consolidation therapy to assure long-term disease-free survival of poor-risk patients.

A four-year-old boy with stage IV neuroblastoma was treated using the group study protocol of the Tohoku area for advanced neuroblastoma, consisting of DTIC, CPA, VCR, CDDP and VM-26, as a result of which had obtained complete remission. However, he had severe hemorrhagic cystitis after administration of CPA. He was treated with the usual therapy, but symptoms such as hematuria, pollakiuria and miction pain were not improved. We then tried bladder irrigation with prostaglandin E2. Half a milligram of PGE2 in 100 ml of physiological saline solution was instilled into the bladder and left in situ for 3 hours. The patient was free of symptoms on the day following the therapy. Local therapy with PGE2 thus seems very useful for cyclophosphamide-induced cystitis.

Seven drugs were administered to nude mice with transplanted TNB9 neuroblastoma. DTIC, cyclophosphamide and ifosfamide were the first-line drugs against TNB9. Chemotherapy including ifosfamide was effective to three of six children with malignant solid tumor resistant to cisplatin and/or cyclophosphamide. Two of the patients who were pretreated with radiotherapy were found to have hemorrhagic cystitis after ifosfamide administration. It therefore seems that chemotherapy with ifosfamide should be withheld after radiotherapy.

Intensive chemotherapy followed by infusion of cryopreserved autologous bone marrow (ABMR) was used in the treatment of 22 children with advanced tumours. In nine this was their initial therapy; in eight it was used after partial or complete remission had been achieved with standard therapy; and in five, after relapse had occurred. Recovery of marrow function occurred in 20 patients with a mean time of 13.2 and 18.2 days to recovery of neutrophils (greater than 0.5 X 10(9)/l) in newly diagnosed and previously treated patients respectively. Platelet count recovery to greater than 50 X 10(9)/l occurred in a mean time of 13.4 days in newly diagnosed and 20.4 days in previously treated patients. Control of extensive local tumour was obtained in three of three evaluable patients with abdominal non-Hodgkin's lymphoma (NHL). Metastatic bony and marrow disease was controlled in two of two patients with retinoblastoma. In Ewing's sarcoma, temporary control of widespread metastatic disease occurred in one patient. In the other, eradication of extensive local mass disease at the primary site had been achieved. Poor response to treatment has been seen in seven of eight patients with Stage III or IV rhabdomyosarcoma, three patients with neuroblastoma and four of five patients with recurrent disease. Apart from the anticipated bone marrow toxicity, the major complications were severe mucositis, anaphylaxis following bone marrow infusion and haemorrhagic cystitis. The presence of herpes simplex infection appeared to aggravate mucosal complication.(ABSTRACT TRUNCATED AT 250 WORDS)

Sixty patients consisting of 56 cases with leukemia, 3 with lymphoma and 1 with neuroblastoma were treated with various kinds of hematopoietic stem cell transplantation. The conditioning regimen consisted of mainly cyclophosphamide (CTX) and total body irradiation (TBI) with the addition of 1-3 doses of other antitumor drugs e.g. cytarabine, daunomycin, etoposide, 6-MP etc. The overall incidence of hemorrhagic cystitis in the course of transplantation was 23.3% (14 out of 60 patients). The time of onset of hematuria in 6 of 14 patients was within 1-4 days following high-dose CTX during conditioning and in the remaining 8 cases occurred 10-30 days after transplantation. The duration of hematuria lasted 2-31 days (mean, 4 days). Thirteen patients recovered and one patient died from the complication.

Ifosfamide is an active drug in the therapy of paediatric tumours such as rhabdomyosarcoma, Ewings' sarcoma, Wilms' tumour, neuroblastoma, germ cell tumours and lymphomas. Myelosuppression is the major toxicity along with haemorrhagic cystitis. The latter is largely prevented by the use of concomitant mesna.

From March 1991 through 31st December 2007, 2042 patients underwent stem cell transplantation at the Hematology-Oncology and Stem Cell Transplantation Research Center, affiliated to Tehran University of Medical Sciences. These transplantations included 1405 allogeneic stem cell transplantation, 624 autologous stem cell transplantation, and 13 syngeneic stem cell transplantation. Stem cell transplantation was performed for various diseases including acute myelogenous leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic lymphoblastic leukemia, thalassemia major, sickle cell thalassemia, sickle cell disease, multiple myeloma, myelodysplasia, mucopolysaccharidosis, paroxysmal nocturnal hemoglobinuria, non-Hodgkin's lymphoma, Hodgkin's disease, severe aplastic anemia, plasma cell leukemia, Niemann-Pick disease, Fanconi anemia, severe combine immunodeficiency, congenital neutropenia, leukocyte adhesion deficiencies, Chediak-Higashi syndrome, osteopetrosis, histiocytosis X, Hurler syndrome, amyloidosis, systemic sclerosis, breast cancer, Ewing's sarcoma, testicular cancer, germ cell tumors, neuroblastoma, medulloblastoma, renal cell carcinoma, nasopharyngeal carcinoma, ovarian cancer, Wilms' tumor, rhabdomyosarcoma, pancreatoblastoma, and multiple sclerosis. We had 105 cellular therapies for postmyocardial infarction, multiple sclerosis, cirrhosis, head of femur necrosis, and renal cell carcinoma. About 30 patients were retransplanted in this center. About 74.9% of the patients (1530 of 2042) remained alive between one to 168 months after stem cell transplantation. Nearly 25.1% (512 of 2042) of our patients died after stem cell transplantation. The causes of deaths were relapse, infections, hemorrhagic cystitis, graft versus host disease, and others.
