Regional hyperthermic perfusion with melphalan after surgery for recurrent malignant melanoma of the extremities. Swedish Melanoma Study Group.

A prospective randomized trial testing regional hyperthermic perfusion with melphalan has been conducted. Sixty-nine patients with recurrent malignant melanoma of the extremities were randomly allocated to surgery (36 patients) or surgery plus regional perfusion (33 patients). Prognostic variables concerning primary tumor as well as the recurrent disease were evenly distributed in the groups, excluding any bias in the randomization. Median tumor-free survival after randomization was 17 months in the perfusion group and 10 months in the control group. There were 15 locoregional recurrences in t…

Gemcitabine, Fludarabine, and Melphalan for Reduced-Intensity Conditioning and Allogeneic Stem Cell Transplantation for Relapsed and Refractory Hodgkin Lymphoma.

Forty patients (median age, 31 years; range, 20 to 63) with Hodgkin lymphoma underwent an allogeneic stem cell transplant with the gemcitabine-fludarabine-melphalan reduced-intensity conditioning regimen. Thirty-one patients (77%) had undergone a prior autologous stem cell transplant, with a median time to progression after transplant of 6 months (range, 1 to 68). Disease status at transplant was complete remission/complete remission, undetermined (n = 23; 57%), partial remission (n = 14; 35%), and other (n = 3; 8%). Twenty-six patients (65%) received brentuximab vedotin before allotransplant.…

High-dose melphalan with autologous stem cell support in refractory Hodgkin lymphoma patients as a bridge to second transplant.

Persistence of disease after salvage therapy among relapsed or refractory Hodgkin lymphoma (HL) patients predicts poor outcome. Here, we report on 41 HL patients with active disease after salvage therapy and who received high-dose melphalan (HD-PAM) and auto-SCT as a bridge to a second autologous or an allogeneic transplantation between 2002 and 2013 at our center. Disease response was based on 18-fluoro-deoxyglucose-positron emission tomography results in all patients. Overall response rate after HD-PAM was 78% and it did not differ among PR or stable/progressive disease patients (P=1.00). Re…

Gain of chromosome 1q21 is an independent adverse prognostic factor in light chain amyloidosis patients treated with melphalan/dexamethasone.

Chromosomal aberrations of plasma cells are well established pathogenetic and prognostic factors in multiple myeloma, but their prognostic implication in systemic light chain (AL) amyloidosis is unclear. Therefore, the aim of this study was to identify prognostic cytogenetic risk factors by interphase FISH in a series of 103 consecutive AL amyloidosis patients treated uniformly with melphalan/dexamethasone as first-line therapy. Detection of gain of 1q21 was predictive for a poor overall survival (OS) (median 12.5 versus 38.2 months, p = 0.002). Hematologic event free survival (hem EFS) for ga…

A randomized phase 2 trial of a preparative regimen of bortezomib, high-dose melphalan, arsenic trioxide, and ascorbic acid.

BackgroundBortezomib is active for newly diagnosed and relapsed multiple myeloma, and it has synergistic activity with melphalan. The authors of this report conducted a randomized trial to determine the safety and efficacy of adding bortezomib to a preparative regimen of arsenic trioxide (ATO), ascorbic acid (AA), and melphalan.MethodsAmong 60 patients who enrolled between October 2006 and September 2007, 58 patients underwent autologous transplantation with a preparative regimen of melphalan 200 mg/m(2) intravenously, AA 1000 mg daily intravenously for 7 days, and ATO 0.25 mg/kg intravenously…

Long-Term Results of Fludarabine/Melphalan as a Reduced-Intensity Conditioning Regimen in Mantle Cell Lymphoma: The GELTAMO Experience.

METHODS: The allo-RIC consisted of fludarabine plus melphalan and peripheral blood hematopoietic stem cells (PBSCs) from human leukocyte antigen (HLA)-identical siblings were used in all cases. Median CD34+ infused cells was 5.8 times 10(6)/kg. All patients engrafted promptly. RESULTS: Early toxicity included mild/moderate mucositis (43%), feb…

Oral glutamine for the prevention of oral mucositis associated with high-dose paclitaxel and melphalan for autologous bone marrow transplantation.

OBJECTIVE: To determine the effect of glutamine suspension on mucositis associated with the administration of high-dose preparative regimens for bone marrow transplantation. METHODS: We performed a retrospective analysis of 21 consecutive patients receiving high-dose paclitaxel and melphalan as the preparative regimen for autologous peripheral blood stem-cell transplantation for metastatic breast cancer between January 1997 and December 1997. Glutamine suspension was given as swish-and-swallow administration every four hours around the clock starting day-7, for a total dose of 24 g/d. RESULT…

Double-conditioning regimens consisting of thiotepa, melphalan and busulfan with stem cell rescue for the treatment of pediatric solid tumors.

Major dose-limiting factors of high-dose thiotepa (TEPA) and melphalan are life-threatening mucositis and neurotoxicity. To administer a maximum dose of these drugs safely and to obtain a maximum anti-cancer effect, a double-conditioning regimen with a single grafting, two cycles of administration of a combination of TEPA (300-600 mg/m2) plus melphalan (70-150 mg/m2) with a 1-week interval was attempted in 20 patients with pediatric advanced or chemotherapy-resistant solid tumors (seven rhabdomyosarcoma, four hepatoblastoma, three neuroblastoma and four other malignancy). Combinations of TEPA …

Воздействие моделей перорального ухода на профилактику перорального слизистого слизняка, вызванного высокими дозами мельфалана у пациентов, страдающих АЦТ.

Высокодозированные мелфаланы (МЭЛ) в сочетании с аутологической трансплантацией стволовых клеток (ASCT) эффективно лечат множественные миеломы (MM), но часто вызывают оральный слизистой мукосит (OM), влияющий на исход пациента. Цель этого исследования заключается в оценке эффективности усовершенствованной модели орального ухода в деле предотвращения ОМ, вызванного МЭЛ. В этом ретроспективном исследовании были рассмотрены медицинские записи 87 больные с MM, которые прошли ACCT в первой родственной больнице Сокхоуского университета в декабре 2019 и февраль 2022.

A Review of Propylene Glycol-free Melphalan Conditioning for Hematopoietic Cell Transplantation for Multiple Myeloma and Light Chain Amyloidosis.

Autologous hematopoietic cell transplantation (AHCT) remains a standard therapeutic option for patients with multiple myeloma (MM). Outcomes have improved for this patient group after first AHCT, with the use of novel agents in induction, as well as post-transplantation maintenance. High-dose melphalan remains the gold standard as the conditioning regimen for MM. Traditional melphalan is a lyophilized formulation that after reconstitution has insufficient chemical stability and water solubility, thus requiring the addition of propylene glycol to act as a cosolvent to improve these characterist…

A fludarabine and melphalan reduced-intensity conditioning regimen for HSCT in fifteen chronic granulomatous disease patients and a literature review.

Chronic granulomatous disease (CGD) is a life-threatening immunodeficiency condition. To date, hematopoietic stem cell transplantation (HSCT) is the only curative modality. We prospectively studied the outcomes of fifteen CGD patients undergoing HSCT with fludarabine and melphalan plus anti-thymocyte globulin (ATG). Most of the donors were fully matched siblings (n = 12). Cyclosporine A and methylprednisolone were used for graft-versus-host disease (GVHD) prophylaxis. CGD diagnosis had been suspected upon clinical symptoms and was confirmed in all patients by an abnormal neutrophil functional …

Effect of Primary and Secondary Beads of Carbon Enterosorbent on Haematological Parameters and Oxidative Stress Development Caused by Melphalan in Rats.

Background and Objectives: Side effects of anti-cancer drugs are usually accompanied by oxidative stress, including myelotoxicity. We evaluated the potential of oral highly activated micro-/macroporous carbon adsorbents (bulk density of 0.16 g/cm3, surface area calculation by Brunauer-Emmett-Teller model (SBET) > 2200 m2/g, derived from proprietary phenolic resin beads) to alleviate oxidative stress and myelotoxicity in rats. Materials and Methods: A single injection of cytostatic melphalan (L-PAM) at a dose of 4 mg/kg was used for modelling. Two forms of activated carbon were used: AC1-primar…

Eye Salvage with Combination of Intravitreal and Intracameral Melphalan Injection for Recurrent Retinoblastoma with Anterior Chamber Involvement: Report of a Case.

AIMS: Herein we report successful eye salvage following combined intravitreal and intracameral administration of melphalan for anterior chamber recurrence of retinoblastoma. METHODS: A 12-month-old boy was referred with a sporadic bilateral retinoblastoma staged as group D and V in the right eye and group E and V in the left eye. Treatment initially involved 6 cycles of 3 drugs followed by focal treatments. The left eye was enucleated. Three months after the end of systemic chemotherapy, multiple recurrent lesions were noted in the ciliary body and the anterior chamber. A series of intravitre…

Intracameral Chemotherapy (Melphalan) for Aqueous Seeding in Retinoblastoma: Bicameral Injection Technique and Related Toxicity in a Pilot Case Study.

BACKGROUND: The anterior chamber has been shown by pharmacokinetic studies to represent a sanctuary never achieving a tumoricidal dose with … and intravitreal chemotherapies. Sterilization of the aqueous was achieved after a first cycle of 7 melphalan injections in the anterior chamber, but relapse was noted 3.5 months later. This relapse was finally controlled with a second cycle of 6 intracameral injections targeting the posterior chamber. Corneal endothelial cell density remained stable over t …

Melphalan-induced apoptosis of EBV-transformed B cells through upregulation of TAp73 and XAF1 and nuclear import of XPA.

Melphalan (Mel) is widely used to treat patients with hematologic cancer, including multiple myeloma, but its mechanism of action in EBV-transformed B cells is poorly described. In this study, we demonstrate a novel mechanism by which transcriptionally active p73 (TAp73) induces translocation of X-linked inhibitor of apoptosis protein-associated factor 1 (XAF1) and xeroderma pigmentosum group A (XPA) during apoptosis caused by Mel treatment. We observed that Mel induced significant generation of reactive oxygen species (ROS) and subsequent apoptosis, as well as an early phosphorylation of p38 …

A case of severe hemorrhagic cystitis caused by melphalan with successful bladder preservation by ligation of bilateral internal iliac arteries.

Hemorrhagic cystitis is a disorder which causes bleeding from diffusely inflammatory bladder mucosa. Here we present a case of severe hemorrhagic cystitis caused by melphalan. A 70-year-old man with multiple myeloma was presented with suddenly commenced massive gross hematuria. During an attempt of transurethral coagulation of bladder mucosa, bladder perforation into peritoneal cavity was suspected, then open laparotomy was indicated. We isolated bilateral internal iliac arteries and ligated them in order to control continued bleeding. After that, bladder bleeding was suddenly diminished. Liga…

Technique and results of hyperthermic isolated hepatic perfusion with tumor necrosis factor and melphalan for the treatment of unresectable hepatic malignancies.

BACKGROUND: For a variety of histologies, the liver represents the only or the dominant site of metastatic disease. Regional treatment of the liver has the theoretic advantage of maximizing drug delivery while minimizing systemic toxicity. This article describes the technique of isolated hepatic perfusion using tumor necrosis factor and melphalan under conditions of moderate hyperthermia for the treatment of unresectable liver tumors. STUDY DESIGN: Fifty patients with biopsy-proved unresectable primary or metastatic cancer to the liver were treated. Isolated hepatic perfusion was performed fo…

High-dose melphalan with or without marrow transplantation: a study of dose-effect in patients with refractory and/or relapsed acute leukemias.

Dose-effect relationships of high-dose melphalan were evaluated in 37 patients with measurable relapsed or refractory acute leukemias. Thirteen patients (Group 1) received 70-100 mg/m2 of melphalan without marrow rescue and 24 patients (Group 2) received 140-180 mg/m2 of melphalan followed by marrow transplantation. Patients in both groups were comparable with respect to age, sex, diagnosis, and status of the leukemia. The complete remission rate was 23% in Group 1 versus 75% in Group 2 (P less than 0.01). Hematological recovery of remission patients was not statistically different in either g…
