Acute transient parotitis after high dose etoposide and autologous bone marrow transplantation.

Etoposide is an important component of several intensive therapy regimens in allogeneic and autologous bone marrow transplantation for advanced hematologic malignancies. We observed the occurrence of transient acute parotid and submandibular sialoadenitis in nine of 19 patients receiving high dose etoposide and melphalan followed by autologous bone marrow rescue. Manifestations included pain, tenderness and swelling of the parotid and submandibular glands. Symptoms arose 4-16 h after completion of etoposide infusion and resolved within 72 h. Elevation of serum amylase accompanied the symptoms, and was also observed in some patients who were asymptomatic. Discomfort was controlled with analgesics and the clinical course was uncomplicated in all cases. Transient parotitis is a relatively frequent and benign complication of high dose etoposide therapy.     

Second marrow transplants in patients with leukemia who relapse after allogeneic marrow transplantation

Twenty-six patients with recurrent leukemia following allogeneic marrow transplantation received a second marrow transplant between 1.5 and 78 months (median 26) after the initial transplant. Preparative regimens for second transplant included multi-agent chemotherapy with total body irradiation, 2.0-10.0 Gy (five patients), dimethylbusulfan alone (one patient), and dimethylbusulfan or busulfan plus cyclophosphamide (20 patients). One patient died before engraftment of infection and 18 died after engraftment from veno-occlusive disease (4), infection (2), idiopathic pneumonia (3), cytomegalovirus pneumonia (3), leukemia (5) and encephalopathy (1). Seven patients (27%) survive 12-38 months (median 26); five (19%) are disease-free and two have recurrent leukemia. Two of the five disease-free survivors have chronic graft-versus-host disease. All of the surviving patients received dimethylbusulfan or busulfan plus cyclophosphamide and six of the seven surviving patients were among 11 patients transplanted more than 2 years after the first transplant whereas only one was among the 15 transplanted in less than 2 years. Those who have second marrow transplants one or more years after their initial transplant are more likely to benefit, while those who are less than 1 year from initial transplant appear to benefit the least.     

Isolated testicular relapse in a boy with acute lymphoblastic leukemia following allogeneic bone marrow transplantation

About 5-10% of boys with acute lymphoblastic leukemia (ALL) present with isolated testicular relapse. Very frequently these relapses occur during treatment or in the following six months, and in these cases the prognosis is very severe. The patients are usually treated with radiotherapy and chemotherapy or bone marrow transplantation (BMT). Testicular relapses after BMT are relatively rare. We report the case of a child with ALL who presented testicular relapse during therapy and was treated with local radiotherapy (2000 cGy), chemotherapy and allogeneic matched BMT. The preparative regimen consisted of Cyclophosphamide (60 mg/kg/day x 2 days) and total body irradiation (200 cGy x 2/day x 3 days). Engraftment was documented at day + 14. The patient presented again with testicular relapse at day + 146, and was therefore treated with orchiectomy, local radiotherapy and systemic chemotherapy. A marrow relapse followed, however, at day + 284 and the patient died of progressive disease.     

In vivo differentiation of leukaemic blasts and effect of low dose Ara-C in a marrow grafted patient with leukaemic relapse

The possible induction of differentiation of leukaemic cells by low dose cytosine arabinoside (Ara-C) was studied in an human chimaera with leukaemic relapse. A 35-year-old woman had been grafted with bone marrow from her HLA identical sister and developed a leukaemic relapse of the host type demonstrated by typing phosphoglucomutase 1 isoenzymes. Before treatment with low dose Ara-C only leukaemic cells and a part of the mature granulocytes were of host type. Lymphocytes, platelets and erythrocytes were still of donor type. The leukaemic cells and the mature host type granulocytes disappeared and the patient went into complete remission after treatment with low dose Ara-C. The results indicate that (a) the leukaemic blasts could differentiate in vivo into mature granulocytes, (b) leukaemic transformation was limited to granulopoiesis, and (c) low dose Ara-C acted as a cytotoxic drug instead of inducing differentiation of host type granulopoiesis.     

Second bone marrow transplantation after leukemia relapse in 11 patients

Since June 1977 eight patients with acute leukemia and three with chronic myelogenous leukemia (CML) have undergone cytoreductive therapy prior to a second allogeneic or syngeneic bone marrow transplantation (BMT). The median age was 24 years (range 7-49 years) and the median time to second BMT was 495 days (range 122-1887 days). Prompt hematopoietic recovery was documented in 11/11 patients and verified by cytogenetic analysis in 7/11. Early death (less than 100 days) was the result of sepsis in one, veno-occlusive disease in one and interstitial pneumonitis in two. Of seven patients who survived beyond 1 year, two patients subsequently died, one as a result of acute respiratory failure and one of leukemia relapse. Five are currently disease-free at 8+, 20+, 42+, 49+ and 72+ months after the second BMT. In this patient population which is at high risk for resistant disease and treatment-related toxicity, a second preparative therapy and BMT may offer a durable disease remission with tolerable toxicity.     

Treatment of infant leukemia with busulfan, cyclophosphamide +/- etoposide and bone marrow transplantation.

Infants with acute leukemia have a poor chance of being cured by conventional chemotherapy. We therefore treated cases of infant leukemia with high dose chemotherapy followed by bone marrow transplantation (BMT). Six suffered from acute leukemia and one from refractory anemia with excess of blasts (RAEB-t). The conditioning regimen consisted of busulfan (BU) and cyclophosphamide (CY), and was intensified by adding etoposide (VP) in four cases. At the time of BMT the children were 4, 5, 12, 13, 13, 14, and 20 months old. Three children were autografted, three received HLA-identical marrow from a sibling donor, and one child received matched unrelated donor marrow. All five children who were grafted in complete (CR) or partial remission (PR) are alive and well in CR 7, 13, 24, 37, and 46 months after allogeneic (two patients) or autologous (three patients) BMT, and 13, 17, 29, 42, and 53 months after initial diagnosis. The child with RAEB-t and the one transplanted in second chemotherapy-resistant relapse of acute non-lymphoblastic leukemia relapsed at 7 and 17 months respectively. The chemotherapy regimen was well tolerated. BU-CY-VP is a promising alternative treatment to regimens including total body irradiation for very young children suffering from acute leukemia.     

Pregnancies following high-dose cyclophosphamide with or without high- dose busulfan or total-body irradiation and bone marrow transplantation

Patients successfully treated with a marrow transplant often have concerns about fertility and pregnancy. This study was performed to determine pregnancy outcome among patients who had received high-dose chemotherapy alone or with total-body irradiation (TBI) and marrow transplantation for aplastic anemia or hematologic malignancy. Records of 1,326 postpubertal and 196 prepubertal patients currently more than 12 years of age after marrow transplant in Seattle from August 1971 to January 1992 were reviewed to determine the patients with normal gonadal function and pregnancies. Among 708 postpubertal women, 110 recovered normal ovarian function and 32 became pregnant. In addition, nine formerly prepubertal girls with normal gonadal function became pregnant. Among 618 postpubertal men, 157 recovered testicular function and partners of 33 became pregnant. An additional two formerly prepubertal men had partners who became pregnant. Forty-one female patients and partners of 35 male patients had 146 pregnancies after transplant. All 76 patients responded to a questionnaire requesting pregnancy history, outcome, infant birth weight, and congenital anomalies information for all clinically recognized pregnancies. There were 115 live births among 146 (79%) pregnancies. Spontaneous abortion terminated four of 56 (7%) pregnancies for 28 female cyclophosphamide (CY) recipients and six of 16 (37%) pregnancies for 13 TBI recipients (P = .02). Partners of 28 male CY recipients had four of 62 (6.4%) pregnancies terminate with spontaneous abortion, but there were no spontaneous abortions among eight pregnancies of five TBI recipients' partners. Preterm delivery occurred for eight of 44 (18%) and five of eight (63%) live births for 24 CY and eight TBI female recipients (P = .01). This 25% incidence among all female patient pregnancies is higher than the expected incidence of 8% to 10% (P = .0001). The 13 preterm deliveries resulted in 10 low birth weight ([LBW] 1.8 to 2.24 kg) and three very low birth weight ([VLBW] < or = 1.36 kg) infants, for an overall incidence of 25%, which is higher than the expected incidence of 6.5% for the general population (P = .0001). Twelve of the 13 premature infants survive. Congenital anomalies were seen among two of 52 (3.8%) live-born infants of female and six of 63 (9.5%) live-born infants of male patients, which is not different from the 13% of single congenital anomalies reported for the general population. These data demonstrate that clinically recognized pregnancies among women who have received a marrow transplant incorporating TBI are likely to be accompanied by an increased risk of spontaneous abortion. Pregnancies among all women who received a marrow transplant are likely to be accompanied by preterm labor and delivery of LBW or VLBW babies who do not seem to be at an increased risk of congenital anomalies. However, determination of possible adverse effects of parental exposure to high- dose alkylating agents with or without TBI on children born posttransplant requires longer, additional follow-up.     

Pulmonary nocardiosis in a patient with CML relapse undergoing imatinib therapy after bone marrow transplantation

We describe a case of pulmonary nocardiosis in a female patient with graft-versus-host disease (GVHD) underwent therapy with imatinib mesylate for a relapse of chronic myeloid leukemia (CML) after allogeneic bone marrow transplantation (BMT). The patient developed chronic GVHD 8 months after the use of imatinib and was on corticosteroid therapy. Three months after the development of chronic GVHD, she acquired pulmonary nocardiosis and a computed tomography (CT) scan of the chest showed multiple nodular lesions with cavitations over both lungs. She was successfully treated with single-agent trimethoprim-sulfamethoxazole (TMP/SMX) and the infection did not recur. Our case indicated that pulmonary nocardiosis could occur in patients with GVHD undergoing imatinib and corticosteroid therapy and might be treated by single-agent TMP/SMX.Conflicts of interest: none for all authors, and there were no extra-institutional grants     

Superior survival after replacing oral with intravenous busulfan in autologous stem cell transplantation for non-Hodgkin lymphoma with busulfan, cyclophosphamide and etoposide

Autologous stem cell transplantation (ASCT) with cyclophosphamide, etoposide and oral busulfan (BuCyVP) is an effective therapy for relapsed or refractory non-Hodgkin lymphoma (NHL). Substituting intravenous for oral busulfan reduces variability in drug exposure, potentially improving the safety and efficacy of the BuCyVP regimen. We retrospectively compared the outcomes of 604 consecutively treated patients who underwent ASCT for NHL with BuCyVP using oral ( n  = 468) or IV ( n  = 136) busulfan, without measurement of busulfan levels for pharmacokinetic (PK) analysis. Patients who received oral busulfan experienced more severe oral mucositis and a higher incidence of nonrelapse mortality. Median overall survival (OS) after ASCT was 72 months with oral busulfan but was not reached for the IV busulfan group. IV busulfan was associated with a lower rate of relapse, and superior relapse-free survival (RFS) and OS. In multivariate models, the route of busulfan administration was an independent prognostic factor for relapse ( P  = 0·01), RFS ( P  = 0·002) and OS ( P  = 0·001). IV busulfan appears to provide better efficacy and lower toxicity than oral busulfan in ASCT with BuCyVP for NHL. Whether PK-based busulfan dosing can achieve further improvements in this setting is worthy of study.     

Autotransplantation following busulfan, etoposide and cyclophosphamide in patients with non-Hodgkin's lymphoma

The purpose of the study was to determine the toxicities and effectiveness of a novel preparative regimen of busulfan (Bu) 14 mg/kg, etoposide 50 or 60 mg/kg, and cyclophosphamide (Cy) 120 mg/kg in non-Hodgkin's lymphoma (NHL) and to analyze results using doses based on different body weight parameters and the two different etoposide doses. Three hundred and eighty-two patients aged 16 to 72 underwent first autologous transplantation with mobilized peripheral blood progenitor cells between August 1992 and December 1998 at either of two transplant centers. Mucositis was the most common toxicity. Hepatic toxicity was the most common life-threatening toxicity; severe hepatic VOD occurred in 11 patients (2.9%). Ten patients (2.6%) died from treatment-related toxicity. The 3-year progression-free survival (PFS) for the entire group was 46.9% (95% CI, 40.5-53.3%). Elevated LDH, resistance to chemotherapy, and intermediate/aggressive histology were significant adverse prognostic factors. For patients in sensitive first relapse PFS was 47.0% (95% CI, 37-57%). Neither etoposide dose nor body weight parameter utilized significantly affected outcome. In conclusion, the novel preparative regimen of Bu, etoposide and Cy results in a low incidence of treatment-related mortality and is effective in the treatment of patients with NHL.

Bone marrow transplantation for leukemia following a new busulfan and cyclophosphamide regimen

Busulfan 16 mg/kg and cyclophosphamide 120 mg/kg were used as conditioning prior to allogeneic marrow transplantation in 50 adult patients with acute nonlymphocytic leukemia (ANLL), acute lymphocytic leukemia (ALL), and chronic myelogenous leukemia (CML). A standard risk group of 20 patients included those with acute leukemia in remission and CML in chronic phase. A high-risk group of 30 patients included individuals with refractory acute leukemia, acute leukemia in relapse, acute leukemia following preleukemia, and CML in accelerated and blastic phase. Complete remission and sustained complete engraftment were achieved in all evaluable patients. The duration of aplasia was remarkably short (median of 8 days), resulting in a low infection rate during the period of neutropenia, a reduced need for blood product support, and a short length of hospital stay. Three-year actuarial relapse-free survival in both standard-risk (88.9% +/- 10.5%) and high- risk (50.5% +/- 9.6%) groups compares favorably with that reported with total body irradiation (TBI) containing regimens.     

High dose busulfan/etoposide as a preparatory regimen for second bone marrow transplants in hematologic malignancies

Summary Five patients with hematologic malignancies who had relapsed between seven months and eight years after their primary bone marrow transplants were prepared with high dose busulfan/etoposide for second marrow transplanatations from the same donors who had provided the marrow for the primary transplants. The preparatory regimen was well tolerated. All patients engrafted and entered complete remission. Two patients are alive and in continued remission two and ten months after second transplant. One patient died with acute respiratory failure after two months and two patients relapsed again eight and 17 months after second marrow transplantation. The combination busulfan/etoposide may prove to be a suitable preparatory regimen for second bone marrow transplant attempts in selected patients.     

Successful HLA-identical bone marrow transplantation in a patient with PNP deficiency using busulfan and fludarabine for conditioning

PNP deficiency is an autosomal recessive metabolic disorder characterized by severe combined immunodeficiency and by complex neurological symptomatology including ataxia, developmental delay and spasticity. Patients usually die in the first or second decade of life due to recurrent infections. The only curative treatment is bone marrow transplantation (BMT). We describe a 22-month-old girl who underwent BMT from her HLA-identical brother. Conditioning consisted of busulfan and fludarabine only, resulting in low toxicity and prompt engraftment. At 18 months after BMT, the girl has developed normal immunological functions, and her neurological status has improved.     

Allogeneic and syngeneic marrow transplantation following high dose dimethylbusulfan, cyclophosphamide and total body irradiation

Fifty-eight patients received an allogeneic or syngeneic marrow transplant following conditioning with high doses of dimethylbusulfan (DMB), cyclophosphamide (CY) and total body irradiation (TBI). Thirty-two patients had either chronic myeloid leukemia (CML) in accelerated phase or blast transformation, or acute leukemia after first relapse. The actuarial survival of these 32 patients at 3 years was 12% compared with 25% for a group of 206 patients with similar diagnoses prepared for transplantation with CY and TBI alone. This reduced survival was associated with a greater incidence of early non-leukemic deaths, in particular as a result of severe hepatic veno-occlusive disease. The incidence of leukemic relapse was not different in the two groups. Of 13 patients with CML in chronic phase who received syngeneic transplants following DMB, CY and TBI, nine are alive in hematologic and cytogenetic remission from 3.9 to 9.4 (median 6.2) years post-transplant.     

Intensive therapy with cyclophosphamide, carmustine, etoposide +/- cisplatin, and autologous bone marrow transplantation for Hodgkin's disease in first relapse after combination chemotherapy [see comments]

The optimal timing in which to use intensive chemotherapy and autologous bone marrow transplantation (BMT) in Hodgkin's disease (HD) is uncertain. In 1985, we initiated a program in which this modality was used as the initial salvage therapy in patients relapsing after combination chemotherapy. Fifty-eight patients with HD in first relapse after primary chemotherapy received conditioning with high-dose cyclophosphamide, carmustine, etoposide (VP16-213) +/- cisplatin (CBV +/- P) followed by autologous BMT. All but six of these patients were given a median of two cycles of conventional chemotherapy +/- involved field radiation therapy before CBV +/- P and autologous BMT. These measures were not used as a means for patients selection; all patients receiving such therapy ultimately were transplanted. The probability of nonrelapse mortality, progression of HD, and progression-free survival post-BMT were calculated, and prognostic factors for progression-free survival were evaluated using the Cox proportional hazards method. Treatment-related deaths occurred in only three patients. Thirteen patients have relapsed at a median 0.7 years (range 0.1 to 3.5) post- BMT. At a median follow-up of 2.3 years (range 0.4 to 7.2), the actuarial progression-free survival is 64% (95% confidence interval, 46% to 78%). In the statistical analysis, three similarly weighted but independent prognostic factors were identified: "B" symptoms at relapse, extranodal disease at relapse, and initial remission duration of less than 1 year. Patients with no risk factors had a 3-year progression-free survival of 100%, compared with 81% in patients with one factor, 40% in those with two factors, and 0% in patients with all three factors. CBV +/- P and autologous BMT is highly effective salvage therapy for HD patients in a first relapse, particularly in the subset of patients with less than two adverse factors. Therapy must be improved in the future for patients with > or = 2 adverse factors.     

Inflammatory peripheral neuropathy following high dose chemotherapy and autologous bone marrow transplantation.

A 40-year-old man with non-Hodgkin's lymphoma developed severe ascending sensorimotor neuropathy 10 days after treatment with high dose chemotherapy and autologous bone marrow rescue. The neuropathy had axonal plus demyelinating features on electrophysiological studies. Sural nerve biopsy showed heavy infiltration of the epineurium and endoneurium with mononuclear cells. The patient had no other evidence of graft-versus-host disease. He failed to respond to plasmapheresis but responded to high dose steroids.     

Fatal veno-occlusive disease of the liver following high dose chemotherapy,irradiation and bone marrow transplantation

In two patients fatal veno-occlusive disease of the liver developed after bone marrow transplantation for underlying malignancies. Both had received significant pretransplant chemotherapy, including cystosine arabinoside, and total body irradiation. The diagnosis of veno-occlusive disease should be considered in patients in whom hepatomegaly, ascites and deteriorating liver function tests develop after they have received cancer chemotherapy.     

Escalating doses of etoposide with cyclophosphamide and fractionated total body irradiation or busulfan as conditioning for bone marrow transplantation

In a phase I study 28 patients with lymphohematopoietic malignancies were treated with escalating doses of etoposide combined with cyclophosphamide 120 mg/kg and either fractionated total body irradiation (TBI) 1320 cGy in 11 fractions (n = 17) or busulfan 16 mg/kg (n = 11). Twenty transplants were allogeneic, seven autologous and one syngeneic. The maximally tolerated dose of etoposide in combination with TBI and cyclophosphamide was 60 mg/kg; at etoposide doses of 65 mg/kg three patients developed life-threatening or fatal mucosal toxicity. In combination with busulfan, the maximally tolerated dose of etoposide was 30 mg/kg. At an etoposide dose of 40 mg/kg two patients developed life-threatening or fatal toxicity (one mucosal, one hepatic). Mucositis requiring narcotic analgesics, hepatotoxicity, hematologic toxicity and interstitial pneumonitis were otherwise similar in TBI and busulfan-treated patients. Skin toxicity was observed significantly more often in the busulfan group. Five deaths occurred before day +30, two in the TBI group and three in the busulfan group. Eleven patients are surviving, ten in continuous complete remission, at a median of 9 (range 3-23) months following transplantation. Etoposide in combination with TBI and cyclophosphamide or busulfan and cyclophosphamide is associated with significant but acceptable toxicities. The maximally tolerated dose of etoposide is higher when combined with TBI than with busulfan. Promising response rates in this high risk group of hematologic malignancies warrant further evaluation of these etoposide containing conditioning regimens.
