Neutropenic enterocolitis in acute leukemia: diagnostic and therapeutic dilemma.
The main purpose of this report is to focus on the importance of an accurate etiologic diagnosis of gastrointestinal complications during chemotherapy for acute myeloid leukemia, taking into account that a syndrome characterized by bowel wall thickening associated with diarrhea and abdominal pain may have etiologies different from neutropenic enterocolitis (NE) and in such a case necessitate a different treatment approach. We describe a case of a 46-year-old woman affected by acute myeloid leukemia presenting the onset of a syndrome with clinical features of NE. Supportive therapy for NE was instituted, but during treatment the patient presented a life-threatening gastrointestinal bleeding and was submitted in emergency to hemicolectomy. Following surgery, the patient recovered completely and she is currently alive in complete remission after receiving allogeneic bone marrow transplantation. Histological examination of the surgical specimens showed that the acute abdominal syndrome was related to massive infiltration of the bowel by leukemia cells. A correct baseline evaluation and a prompt diagnosis of the complication may help in making the therapeutic decision, which in our case led necessarily to a surgical procedure, because the bleeding was due to post-chemotherapy necrosis of the leukemic infiltrating tissue. A close collaboration between the hematologist and the surgeon may provide guidelines for behavior in such cases, giving these patients the possibility of survival and the opportunity to carry on the treatment planned for the primary disease.

Thrombotic thrombocytopenic purpura and pregnancy: a case report and a review of the literature.
Thrombotic thrombocytopenic purpura (TTP) is a severe disorder affecting the microcirculation of multiple organ systems. Plasma therapy has significantly reduced the mortality rate. Infections, pregnancy, cancers, drugs, and surgery were frequently associated with the initial episodes and relapses. Women who are either pregnant or in the postpartum period make up 10-25% of TTP patients, suggesting the interrelationship between TTP and pregnancy. The introduction of aggressive treatment with plasma transfusion or plasmapheresis improved maternal and fetal survival rates. We describe a case of a first successful pregnancy concomitant to a late relapse of TTP, in which the identification of important risk factors for both TTP and pregnancy allowed us easier hematological and obstetrical management. Proposed guidelines for pregnancy-related TTP management and a brief review of current treatment options for this rare condition are also included.

How long can we give interleukin-2? Clinical and immunological evaluation of AML patients after 10 or more years of IL2 administration.
We have treated 20 patients, affected by acute myelogenous leukemia in advanced phase of the disease, with intravenous high-dose recombinant interleukin-2 (IL2) as induction treatment, achieving a complete remission (CR) in 11/20 of patients (55%). All CR patients were planned to receive a maintenance program with lower subcutaneous doses of IL2 until relapse. Currently, 5/11 patients are alive in continuous complete remission with a minimum follow-up of 9 years from IL2 induction. In the aim to investigate the treatment's side-effects during or after prolonged IL2 therapy, we decided to submit these patients to a clinical and immunological evaluation. Four patients have been evaluated as one, who independently stopped IL2 after 6 years, refused the check-up. No organ-specific treatment sequelae that may decrease the quality of life or may be life-threatening were found, concerning renal, liver and cardiovascular function. Endocrine abnormalities were detected in three patients, the most serious being a severe hypothyroidism, which prompted cessation of IL2 maintenance after 6 years and required thyroid supplementation treatment. Immunological studies were carried out prior to the last IL2 cycle and showed high levels of CD3-positive T cells expressing the IL2 receptor alpha chain (CD25), both in the peripheral blood and in the bone marrow. Our study shows that low-dose IL2 can be given for a prolonged period of time without serious organ-specific late sequelae and with a good quality of life.

Obesity and autologous stem cell transplantation in acute myeloid leukemia.
In the bone marrow transplant setting, several authors hypothesized that severely overweight patients are at increased risk of transplant-related toxicity, but different definitions of obesity, different body weight groupings and heterogeneous samples of patients were analyzed. To overcome these limitations, we retrospectively considered a homogeneous group of 54 patients (median age 36.5 years), with a diagnosis of de novo acute myeloid leukemia (AML), autografted in first complete remission (CR) with the Bu-Cy2 conditioning regimen, dosed on actual body weight. Patients were classified into three groups (obese, non-obese, underweight) using body mass index (BMI = kg/m(2)); for each group we analyzed transplant-related toxicity and mortality, overall survival and disease-free survival (OS/DFS). In spite of the relatively small number of patients, in our results high BMI appears a predictive factor for an increase of treatment-related toxicity and mortality. Moreover, 30 (55%) patients are currently alive in continuous CR, and after a median follow-up of 76.5 months (range 14-137) statistically significant differences in OS and DFS were detected between obese and non-obese groups (P = 0.012 and 0.021, respectively). Our study suggests that obesity may represent an independent risk factor for autograft in AML and further investigations are warranted.

Ten-year follow-up of a single center prospective trial of unmanipulated peripheral blood stem cell autograft and interferon-alpha in early phase chronic myeloyd leukemia.
BACKGROUND AND OBJECTIVES: The potential role of autologous stem cell transplantation (ASCT) as an alternative therapeutic strategy in chronic myelogenous leukemia (CML) has been widely explored in pilot studies, but the clinical results in terms of survival have so far been evaluated only retrospectively and in heterogeneous groups of patients. The goal of our prospective study was to evaluate the feasibility and long-term efficacy of unmanipulated ASCT followed by low-dose interferon-alpha in a homogeneous group of patients affected by CML in a very early phase of disease. DESIGN AND METHODS: Twenty-six unselected consecutive patients with CML in chronic phase underwent stem cell collection at diagnosis, then received cytoreductive treatment with hydroxyurea and, subsequently, a busulphan-melphalan myeloablative regimen followed by unmanipulated stem cell graft within one year of diagnosis. Interferon was given a median of 6.5 months after transplant at escalating doses, starting from 0.5 x 10(6) IU 3 times/week, on the basis of the clinical and hematologic tolerance. RESULTS: Median chronic phase duration from diagnosis is 9 years. The ten-year projected probability of overall survival from diagnosis is 55% with a median follow-up of surviving patients of 9.5 years (8-10.5); median survival has not been reached after ten years. INTERPRETATION AND CONCLUSIONS: Our experience suggests that high-dose therapy followed by unmanipulated peripheral blood stem cell transplantation and low-dose interferon-alpha is a feasible approach, which results in long-term survival in newly diagnosed CML patients. These data need to be confirmed in controlled trials comparing ASCT with other therapeutic approaches, such as the use of interferon-alpha alone or in combination with other agents.

Thrombotic thrombocytopenic purpura: prospective neurologic, neuroimaging and neurophysiologic evaluation.
BACKGROUND AND OBJECTIVES: Neurologic symptoms are present in 60% of patients with thrombotic thrombocytopenic purpura (TTP) on initial examination and ultimately develop in about 90% of cases during the course of the disease. Despite central nervous system involvement being frequent, abnormalities in the brain of patients with TTP are infrequent on neuroimaging (CT/MRI) and neurophysiologic (EEG) evaluation, often reversible and mainly limited to symptomatic stages of the disease. The aim of our study was to establish the value of a complete neurologic screening as part of the work up of TTP. DESIGN AND METHODS: We prospectively evaluated 16 TTP patients, performing serial neurologic, neuroimaging and EEG examinations, independently of the presence of an objective central nervous system involvement. RESULTS: Our study shows that a complete neurologic evaluation is of modest help in improving the diagnosis of TTP, but may be useful for the neurologic management. INTERPRETATION AND CONCLUSIONS: Accurate neuroimaging and, especially, EEG evaluation and monitoring allowed us to identify patients who could benefit from anticonvulsive therapy, avoiding the unnecessary administration of the latter. The prognostic utility of complete neurologic screening in TTP remains to be conclusively demonstrated in larger prospective neurologic studies.

High-dose idarubicine, busulphan and melphalan as conditioning for autologous blood stem cell transplantation in multiple myeloma. A feasibility study.
Extensive studies have tested the clinical impact of double and triple sequential transplants as front-line therapy in MM, following the suggestion that dose escalation can overcome the marked drug resistance characteristic of this disease, but the superiority of such approaches vs one single transplant has still to be demonstrated. The aim of our study was to evaluate the feasibility and efficacy of high-dose idarubicine intensification of a standard busulphan-melphalan conditioning regimen in MM. Twenty-eight patients (median age 55 years) with sensitive disease received PBSCT after high-dose idarubicine combined with busulphan and melphalan and followed by s.c. rhG-CSF until PMN recovery. The most severe toxicity was represented by oral mucositis which resolved with hemopoietic reconstitution. Overall response and CR rate were 52% and 40%, respectively. Currently, 36 patients are alive and 19 are progression-free a median of 20 months (12-36) from transplant. The 3-year projected probability of progression-free survival for patients transplanted after first-line treatment is 60%. The combination of Ida/Bu/Melph appears a promising alternative regimen for PBSCT in myeloma, with low transplant-related toxicity and fast hematological recovery. Long-term follow-up and a prospective randomized study, now ongoing, will probably clarify whether an idarubicine-intensified regimen will result in superior outcomes to conventional conditioning and even be comparable to a double consecutive transplant program.

Unmanipulated peripheral blood stem cell autograft in chronic lymphocytic leukemia: clinical findings and biological monitoring.
BACKGROUND AND OBJECTIVES: To investigate the feasibility of peripheral blood stem cell (PBSC) transplantion in patients with high-risk chronic lymphocytic leukemia (CLL) in remission after fludarabine therapy, the clinical impact of minimal residual disease (MRD) monitoring and the immunologic reconstitution after transplantation. DESIGN AND METHODS: Twenty CLL patients, in clinical complete remission (CR) after fludarabine, were offered an unmanipulated PBSC transplant and were longitudinally monitored for MRD and immunologic reconstitution. RESULTS: Due to unsatisfactory PBSC collection, 4 patients received bone marrow cells. All patients engrafted. Two patients died, one due to infection and one because of another neoplasia. Thirteen patients are at present in clinical CR after a median follow-up of 17 months and 18 patients are alive with a survival probability of 0.87 (+/-0.04) at 52 months after transplant. Fifteen patients had a molecular remission. Three of them showed a molecular relapse 16-28 months after autograft, followed by a clinical relapse 10-16 months later. Three of the four patients who remained persistently rearranged could be revaluated over time and showed an immunologic relapse 11-26 months after transplant; two of these had a clinical relapse 12 and 7 months later. A marked and persistent impairment of both the B- and T-immunologic compartments was recorded in the horizontal follow-up. INTERPRETATION AND CONCLUSIONS: Unmanipulated PBSC autograft is a feasible procedure that produces prolonged molecular remissions in high-risk CLL patients. Persistence or reappearance of a molecular signal after engraftment is predictive of subsequent immunologic and clinical CLL recurrence. The long -lasting impairment of the host immune repertoire after fludarabine followed by autograft has to be taken into account in the patients' management.

Clinical and metabolic effects of different parenteral nutrition regimens in patients undergoing allogeneic bone marrow transplantation.
BACKGROUND: Nutrients may interfere with physiological and pathophysiologic mechanisms. The present study was aimed at evaluating whether the differences in the quality of energy substrates administered with total parenteral nutrition (TPN) after cytoreductive therapy may influence the clinical outcome of patients undergoing bone marrow transplantation (BMT). METHODS: Sixty-six consecutive allogeneic BMT patients with hematologic malignancies were randomized to receive either a glucose-based (100% glucose) or a lipid-based (80% lipid, using an omega-6 long-chain triacylglycerol emulsion + 20% glucose) TPN, providing 146.3 kJ/kg body weight, 1.4 g of protein/kg of body weight, administered from day +1 to day +15 after BMT. Time to engraftment (EGT), incidence of sepsis and metabolic complications (hyperglycemia and hypertriglyceridemia), incidence of acute graft-versus-host-disease (A-GVHD) and relapse, survival at 18 months, incidence of deaths for A-GVHD and relapse were evaluated. RESULTS: Six patients dropped out before completing the study period. Thirty-one patients in the glucose-based TPN group and 29 patients in the lipid-based TPN group were evaluated. The incidence of hyperglycemia was significantly lower in the lipid-based TPN group than in the glucose-based TPN group (3.4% vs. 32%, respectively; P=0.004). Five patients in the glucose group and none in the lipid group died for A-GVHD (P<0.05). Survival at 18 months tended to be higher in the lipid group than in the glucose group (62% vs. 42%, P=NS). Rate of bone-marrow EGT, time to EGT, incidence of sepsis and fungal infections during TPN, incidence of A-GVHD, and rate of relapse at 18 months were not different in the two groups. CONCLUSIONS: The results obtained suggest that the use of lipid-based TPN after allogeneic BMT is associated with lower incidence of lethal A-GVHD and hyperglycemia, without negatively affecting the EGT of infused cells. Intravenously administered lipids might have influenced the severity of A-GVHD likely via modulation of immune response and synthesis of cytokines, prostaglandins, and leukotrienes that participate in the pathogenesis of graft-versus-host disease.

Autologous bone marrow transplantation for acute promyelocytic leukemia in second remission: prognostic relevance of pretransplant minimal residual disease assessment by reverse-transcription polymerase chain reaction of the PML/RAR alpha fusion gene.
Reverse-transcription polymerase chain reaction (RT-PCR) of the PML/RAR alpha fusion gene may predict relapse in acute promyelocytic leukemia (APL) patients in hematologic complete remission (CR). We have prospectively studied by RT-PCR 15 PML/RAR alpha+ APL patients undergoing autologous bone marrow transplantation (ABMT) in second CR. The median time of first CR duration was 12 months (range, 6 to 40). All patients were reinduced with all-trans retinoic acid (ATRA), followed in 12 of 15 cases by mitoxantrone and Ara-C as consolidation. Fourteen patients received the BAVC (BCNU, Ara-C, m-AMSA, and VP-16) schedule as conditioning regimen. Unpurged marrows were collected immediately before conditioning treatment, analyzed by RT-PCR, and reinfused at median of 2 months (range, 2 to 7) from the achievement of second CR. Seven patients were PCR+ and eight PCR for PML/RAR alpha in their pretransplant marrows. All seven patients of the former group remained PCR+ during the follow-up and relapsed at a median time of 5 months (range, 2 to 9) from ABMT and 9 months (range, 4 to 14) from second CR. Of the eight PCR- patients, all remained PCR- during the follow-up controls. One patient relapsed at 10 months from ABMT, one died of a secondary (PML/RAR alpha-) leukemia, and six are in hematologic and molecular remission at a median time of 28 months (range, 15 to 60) after ABMT and 32 months (range, 17 to 62) from second CR. Our results indicate that, in APL patients in second CR, ABMT with PML/RAR alpha- marrow cells is likely to result in prolonged clinical and molecular remissions. Conversely, patients who test PCR+ after reinduction necessitate the use of alternative aggressive approaches, including unrelated allogeneic transplant.

Etoposide, intermediate-dose cytarabine and carboplatin (VAC): a combination therapy for the blastic phase of chronic myelogenous leukemia.
BACKGROUND: Carboplatin is a second-generation platinum compound that in combination with etoposide and intermediate doses of cytarabine, in early clinical trials has demonstrated high efficacy in refractory acute myelogenous leukemia and the blastic phase of CML. PATIENTS AND METHODS: Starting in April 1992, 17 consecutive patients with the blastic phase (BP) of chronic myelogenous leukemia (CML) and a median age of 33 years (range 10 to 45) received a new treatment regimen consisting of etoposide (100 mg/m2/d i.v. over one hour), intermediate-dose cytarabine (500 mg/m2/d i.v. over one hour, q12 hours) and carboplatin (150 mg/m2/d continuous infusion) on days 1 3 and 8 10 (VAC regimen). The BP phenotype was myeloid in 16 patients and hybrid in one. At the time of their BP diagnoses, two patients showed extramedullary involvement, in eight patients the BP was preceded by an accelerated phase. RESULTS: Overall, 11 of 17 patients (65%) achieved complete remission and 7 of 11 responding patients (64%) manifested a cytogenetic conversion ranging from 38% to 100% Ph-negative metaphases: one patient died in CR of hemothorax, three died of sepsis during induction therapy and three patients (17.5%) had resistant disease. As of April 1996, four patients are alive, three of them in first remission at +7, +10, +16 months after CR, and one in BP at +38 months after the start of VAC therapy. Profound myelosuppression was observed in all patients; extrahematologic toxicity, especially involved the gastro-intestinal tract, with grade > 2 mucositis in five patients (29.5%) and liver dysfunction in five (29.5%). No renal toxicity or ototoxicity was observed. CONCLUSIONS: Despite the brief relapse-free duration, the high remission rate and tolerable toxicity indicate that the VAC combination chemotherapy has a high antileukemic efficacy, and warrants further evaluation for the treatment of CML in acute phase, provided a post-remission BMT strategy is feasible.

Autologous bone marrow transplantation in 44 patients with aggressive non-Hodgkin's lymphoma at University "La Sapienza" of Rome.
High dose therapy followed by infusion of autologous bone marrow has become a major treatment option for an increasing number of poor prognosis non-Hodgkin's lymphoma (NHL) patients. In our study we analyzed the outcome of autologous bone marrow transplantation (ABMT) in 44 high grade NHL patients transplanted at our institution between 1985 and 1992. Median age was 31 years (range 12-61); nineteen were in partial remission (PR) after first line chemotherapy and 25 in sensitive relapse (SR). Of the 25 patients transplanted in SR, 14 relapsed after a median time of 5.5 months (range 1-26), 8 are in complete remission after a median follow up of 41.5 months and three died from toxicity. Of the 19 patients grafted in PR, 11 are alive and progression free after a median follow up of 52 months, while 8 relapsed at a median time of 5 months. The overall progression free survival (PFS) projected at 6 years is 35% with a 47% PFS for patients transplanted in PR and 28% for patients in SR. In conclusion, high dose therapy and ABMT has achieved widespread use as salvage therapy for patients with relapsed/refractory high grade NHL. In particular, our experience confirms that myeloablative treatment is a safe and well tolerated procedure for patients in PR, that may be easily applied as early salvage therapy without major toxicities.

Interleukin-2 for the treatment of advanced acute myelogenous leukemia patients with limited disease: updated experience with 20 cases.
Since 1988 we have treated a first group of 14 patients with recombinant interleukin-2 (rIL-2), which was previously published, and 6 other consecutive patients affected by refractory or relapsed acute myelogenous leukemia (AML) with >5% and < or = 30% bone marrow blasts, but not suitable for further chemotherapy. The rIL-2 schedule consisted of four 5-day high-dose cycles administered by continuous infusion with a 72-hour rest period between each cycle. Patients who achieved a response received a lower dose of subcutaneous rIL-2 maintenance treatment administered for 5 days every month. Following high-dose rIL-2, 11/20 patients (55%) obtained a complete remission (CR). Six remain in persistent CR after a median follow-up time of 50 months (9, 33, 49, 51, 52, 87 months, respectively); the length of remission is the longest in the natural history of the disease for each individual patient. One patient with stable disease at the end of rIL-2 induction is alive and well, with a stable number of blasts in the bone marrow, 18 months later. These 7 patients continue maintenance treatment with subcutaneous rIL-2. Close clinical and laboratory monitoring reveal that side effects are acceptable and no toxic deaths have been recorded. This update confirms the feasibility and antileukemic activity of high dose rIL-2 in advanced AML patients with limited disease, and suggests a potential clinical role of prolonged rIL-2 maintenance treatment.

BAVC regimen and autograft for acute myelogenous leukemia in second complete remission.
Since 1984 we have autografted a total of 60 patients with AML in second complete remission (CR) utilizing the BAVC (BCNU, amsacrine, vepesid, cytosine-arabinoside) conditioning regimen and unpurged marrow. Projected disease-free survival (DFS) probability in 42% at 10 years. Autografting was performed at a median interval of 2 months (range 1-13) from second CR. The median duration of first CR was 14 months (range 1-43) and lasted < or = 12 months in 27/60 patients. Three early deaths (5%) occurred, 30 patients relapsed after a median of 6 months from transplant (range 2-28) and, of the remaining 27 patients, 26 are in continuous CR (CCR) after a median follow up of 60 months (range 6-122), while the last patient committed suicide 7 years after ABMT when she was still in CCR. A first CR duration > 12 months is correlated with a significantly better overall survival probability (61 vs 25%, P = 0.02), while no factors influence DFS. Outcome of patients who relapsed after autografting has been analyzed separately; a longer overall survival after relapse is correlated with a longer duration of the second CR (62% at 34 months for patients who relapsed after > 12 months from the autograft vs 5% for the others, P = 0.001). These results confirm that AML patients autografted in second CR with BAVC regimen and unpurged marrow have the possibility of becoming long-term DFS and can therefore be cured.
