Abstract
PURPOSE The aim of this study was to review the available literature from 1966 until December 31, 2010 and define clinical practice guidelines for the use of amifostine for the prevention and treatment of oral mucositis in cancer patients. METHODS A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology. The body of evidence for the use of amifostine, in each cancer treatment setting was assigned an evidence level. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, or no guideline possible. RESULTS Thirty papers were reviewed for evidence on amifostine as an intervention for oral mucositis. No guideline was possible for amifostine in any cancer treatment setting due to inadequate and conflicting evidence. CONCLUSION Review of the amifostine studies for the prevention and treatment of oral mucositis has found insufficient evidence to support its use in any cancer treatment setting for this purpose. Additional well-designed research is needed to clarify the role of amifostine as an intervention for oral mucositis.

Abstract
Purpose Of patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT), 75 % or more experience oral mucositis, a painful acute complication that can delay discharge, interrupt treatment, and threaten life. To evaluate the efficacy of a supersaturated calcium phosphate rinse (SCPR), we compared it with customary care—topical mouth solutions—on measures of severity and consequent interventions and complications. Methods In this randomized controlled trial, 40 patients undergoing allogeneic HSCT were randomized: 20 to SCPR four times daily and 20 to solutions made with salvia leaf extract, iodine-povidine, and fluconazole. Treatment extended from initiation of conditioning treatment until the granulocyte count was ≥0.2 g/L. Mucositis severity was measured daily by a hematologist according to a World Health Organization (WHO) scale and self-assessed by patients. Need for interventions [analgesics, total parenteral nutrition (TPN), and granulocyte colony-stimulating factor] and complications (acute graft-versus-host disease and infections) were also assessed. Results In comparison with the control group, the SCPR group had significantly lower mean measures of WHO oral toxicity (0.9 vs. 1.8; P = 0.02), disease course (3.2 vs. 7.1 days; P = 0.02), and peak mouth pain (0.85 vs. 1.75; P = 0.005). Analgesic need was significantly shorter (1.1 vs. 3.4 days; P = 0.047) and the need for TPN significantly lower (0 vs. 6 patients; P = 0.02; 0 vs. 1.9 mean days; P = 0.009). Measures of complications were lower in the SCPR group, but not significantly so. Trial limitations include the impracticality of achieving double blinding with agents so different in appearance and in preadministration preparation. Conclusions Compared with the control group, the SCPR group had significantly lower mean measures of oral toxicity, peak mouth pain, and disease course duration. These results warrant confirmation in controlled, multicenter, randomized trials.

Abstract
This study evaluated whether amifostine protects against mucositis and other toxicities in patients with advanced, refractory, or recurrent hematologic malignancies undergoing high-dose chemotherapy and total body irradiation. Thirty-five patients (20 with non-Hodgkin lymphoma, 12 with Hodgkin disease, and 3 with acute myelogenous leukemia) who underwent autologous stem cell transplantation were conditioned with total body irradiation 2 Gy twice daily on days -8 through -6; cyclophosphamide 6 g/m(2), etoposide 1.8 g/m(2), and carboplatin 1 g/m(2) on days -5 through -3; and amifostine 500 mg/m(2) on days -8 through -2. Prior institutional experience in patients treated without amifostine was used as a historical comparison (no-amifostine group). Severe mucositis occurred in 14 (40%) of 35 patients in the amifostine group, compared with 33 (94%) of 35 in the no-amifostine group (P < .0001). Total parenteral nutrition was used by 4 (11%) of 35 amifostine-treated patients and 34 (97%) of 35 no-amifostine patients (P < .0001). The median duration of narcotic use decreased from 15.5 days with no amifostine to 11 days with amifostine (P = .002). Granulocyte and platelet engraftment times were similar. Prospective trials with innovative designs and clearly defined stopping rules are warranted to confirm whether amifostine reduces the toxicities of a myelosuppressive conditioning regimen before autologous stem cell transplantation without compromising therapeutic response.

Abstract
This study was conducted to define a new maximum tolerated dose and the dose-limiting toxicity (DLT) of melphalan and autologous hematopoietic stem cell transplantation (AHSCT) when used with the cytoprotective agent amifostine. Fifty-eight patients with various types of malignancy who were ineligible for higher-priority AHSCT protocols were entered on a phase I study of escalating doses of melphalan beginning at 220 mg/m(2) and advancing by 20 mg/m(2) increments in planned cohorts of 4 to 8 patients until severe regimen-related toxicity (RRT) was encountered. In all patients, amifostine 740 mg/m(2) was given on 2 occasions before the first melphalan dose (ie, 24 hours before and again 15 minutes before). AHSCT was given 24 hours after the first melphalan dose. Melphalan was given in doses up to and including 300 mg/m(2). Hematologic depression was profound, although it was rapidly and equally reversible at all melphalan doses. Although mucosal RRT was substantial, it was not the DLT, and some patients given the highest melphalan doses (ie, 300 mg/m(2)) did not develop mucosal RRT. The DLT was not clearly defined. Cardiac toxicity in the form of atrial fibrillation occurred in 3 of 36 patients treated with melphalan doses >/=280 mg/m(2) and was deemed fatal in 1 patient given melphalan 300 mg/m(2). (Another patient with a known cardiomyopathy was given melphalan 220 mg/m(2) and died as a result of heart failure but did not have atrial fibrillation.) Another patient given melphalan 300 mg/m(2) died of hepatic necrosis. The maximum tolerated dose of melphalan in this setting was thus considered to be 280 mg/m(2), and 27 patients were given this dose without severe RRT. Moreover, 38 patients were evaluable for delayed toxicity related to RRT; none was noted. Tumor responses have been noted at all melphalan doses and in all diagnostic groups, and 21 patients are alive at median day +1121 (range, day +136 to day +1923), including 16 without evidence of disease progression at median day +1075 (range, day +509 to day +1638). Amifostine and AHSCT permit the safe use of melphalan 280 mg/m(2), an apparent increase over the dose of melphalan that can be safely administered with AHSCT but without amifostine. Further studies are needed not only to confirm these findings, but also to define the antitumor efficacy of this regimen. Finally, it may be possible to evaluate additional methods of further dose escalation of melphalan in this setting.

Abstract
We initiated a randomized study of amifostine (the organic thiophosphate formerly known as WR-2721) given to patients during myeloablative conditioning therapy for allogeneic bone marrow transplantation. Amifostine was given at a dose of 1000 mg/day of conditioning and was well tolerated if attention was given to serum calcium levels, blood pressure and antiemetics. Since August 1998, 60 patients (30 on each arm) have completed the study. There was no significant difference in the days to neutrophil or platelet engraftment in either arm of the study. Significantly, the duration of grade I-IV mucositis was decreased in the group that received amifostine (P=0.02). Also grade III or IV infections (P=0.008), duration of antibiotic therapy (P=0.03) and duration of fever (P=0.04) were significantly reduced with amifostine. However, there were no differences in the incidence of grade III or IV mucositis, liver toxicity or renal toxicity. There were also no differences in early mortality, relapse and long-term survival. We conclude that amifostine, while reducing the duration of mucositis and infections (possibly through some preservation of gut mucosal integrity), has a modest effect in allogeneic bone marrow transplants given the multiplicity of factors influencing organ toxicity and survival in this setting.

Abstract
Oral mucosal ulceration is a frequent complication in bone marrow transplantation, resulting from epithelial injury caused by cytotoxic chemotherapy and radiation conditioning, as well as from pre-existing infection. Oral mucositis causes pain, interferes with patient nutrition, and can lead to systemic infection and other complications that increase patient morbidity and mortality; this complication also markedly increases the expense of bone marrow transplantation. A variety of interventions have been assessed for preventing oral mucositis or reducing the severity of mucositis and its sequelae. These include meticulous pretransplantation and ongoing mouth care, calcium phosphate solution, near-infrared light and lower-energy laser treatment, interleukin-11, sucralfate, oral glutamine, granulocyte-macrophage colony-stimulating factor rinse, tretinoin, and keratinocyte growth factor; particularly promising results have been observed with use of the cytoprotectant/radioprotectant agent amifostine. Reduction in the severity and duration of oral mucositis and its sequelae in patients undergoing bone marrow transplantation can have a substantial impact on morbidity and mortality and cost of care. Further systematic evaluation of approaches to prevention and management of oral mucositis is necessary to define optimal strategies in the transplantation setting.

Abstract
High-dose chemotherapy using melphalan (HDMEL) is an important component of many conditioning regimens that are given before autologous hematopoietic stem cell transplantation (AHSCT). In contrast to the situation in myeloma, and to a lesser degree acute leukemia, only a very limited published experience exists with the use of HDMEL conditioning as a single agent in doses requiring AHSCT for lymphoma, both Hodgkin lymphoma (HL) and especially non-Hodgkin lymphoma (NHL). Thus, we report results of treating 26 lymphoma patients (22 with NHL and four with HL) with HDMEL 220-300 mg/m(2) plus amifostine (AF) cytoprotection and AHSCT as part of a phase I-II trial. Median age was 51 years (range 24-62 years); NHL histology was varied, but was aggressive (including transformed from indolent) in 19 patients, indolent in two patients and mantle cell in one. All 26 patients had been extensively treated; 11 were refractory to the immediate prior therapy on protocol entry and two had undergone prior AHSCT. All were deemed ineligible for other, 'first-line' AHSCT regimens. Of these 26 patients, 22 survived to initial tumor evaluation on D +100. At this time, 13 were in complete remission, including four patients who were in second CR before HDMEL+AF+AHSCT. Responses occurred at all HDMEL doses. Currently, seven patients are alive, including five without progression, with a median follow-up in these latter patients of D +1163 (range D +824 to D +1630); one of these patients had a nonmyeloablative allograft as consolidation on D +106. Conversely, 14 patients relapsed or progressed, including five who had previously achieved CR with the AHSCT procedure. Two patients, both with HL, remain alive after progression; one is in CR following salvage radiotherapy. Six patients died due to nonrelapse causes, including two NHL patients who died while in CR. We conclude that HDMEL+AF+AHSCT has significant single-agent activity in relapsed or refractory NHL and HL. This experience may be used as a starting point for subsequent dose escalation of HDMEL (probably with AF) in established combination regimens.

Abstract
Background. Oral mucositis is a common complication of some malignancies treatment, causing therapeutic modifications due to patient's debilitation, which often interferes with the prognosis of the disease. Many attempts have been made to find an optimal treatment or preventive method to minimize the severity of oral mucositis. Several studies have shown good results with the use of low-energy laser, with the aim of accelerating the process of wound healing and promoting pain relief. Methods. Patients (n=18) who developed oral mucositis during chemotherapy and/or radiotherapy were submitted to low-energy laser applications until cessation of symptoms. Mucositis severity was scored by an oral mucositis scale based on clinical features and by an oral toxicity scale from the National Cancer Institute based on the ability to swallow; pain severity was scored by subjects on a visual analogue scale before and after the applications. Results. Immediate pain relief was achieved in 66.6% of the patients after the first application. Based on the functional scale, mucositis grade III (not capable to eat solids) was reduced in 42.85% of the cases. According to the scale based on the clinical features, mucositis grade IV (ulcerative lesions) was reduced in 75% of the patients that presented this grade of mucositis at the beginning of laser therapy. Conclusions. Low-energy laser was well-tolerated and showed beneficial effects on the management of oral mucositis, improving the quality of life during the oncologic treatment.

Abstract
The objective of this prospective study was to determine whether amifostine (Ethyol) reduced conditioning-related toxicity following a regimen of busulfan (7 mg/kg) and fractionated total body irradiation (6 x 200 cGy). In all, 12 patients with advanced myelodysplastic syndrome transplanted from HLA-identical siblings were enrolled. Patients received 340 mg/m(2) amifostine i.v. twice daily during conditioning (days -7 through -1). All patients developed oropharyngeal mucositis. Six patients had evidence of sinusoidal obstruction syndrome of the liver. Six patients experienced pulmonary toxicity of grades II-III. A total of 11 patients died, one with relapse and 10 with infectious complications or regimen-related toxicity. Nonrelapse causes of death included invasive aspergillosis in three, multiorgan failure in three, and idiopathic interstitial pneumonitis in two patients. One patient each died of organizing pneumonia and CMV pneumonia. One patient is alive in complete remission 31 months after transplantation. These results were not superior to those in patients conditioned with busulfan plus fractionated total body irradiation and not given amifostine, and suggest that amifostine, as administered here, has no protective effect against toxicity from this myeloablative regimen.

Abstract
Renal function greatly influences mortality rates in the early phase following hematological stem cell transplantation (HSCT) in childhood, as well as the quality of life in long-term survivors. Nevertheless, the number of studies in pediatric populations is limited and some important aspects of kidney function after HSCT have only been elucidated in adults. The incidence of acute renal failure (ARF) immediately after HSCT in pediatric patients is between 25% and 50%, with 5%-10% of children requiring renal replacement therapy. Doubling of serum creatinine is associated with a twofold increase in mortality. However, the need for dialysis leads to a further increase in mortality rates to 80%-90%. Specific renal syndromes appear at different times following HSCT, revealing a similar pattern in children and adult patients. In both children and adults, impaired renal function associated with liver impairment (hepatorenal syndrome) is the most important cause for ARF. Therapeutic approaches have not been able to reduce the frequency or to improve outcome so far. In adults surviving long term, bone marrow transplant (BMT) nephropathy is the most frequent renal complication, although a considerable variation in incidence (up to 70%) has been published, partly due to various definitions and manifestations. Little is known about the long-term outcome of renal function in patients treated with HSCT in childhood. However, chronic renal failure has been reported in 0%-28%, but no end-stage renal failure has been published so far. Tubular function following HSCT is rarely investigated, although its impact on long-term survivors of BMT in childhood might be of some importance, especially for growth and bone metabolism.

Abstract
Oral mucositis is a complication common to many cancer therapies and produces considerable pain and morbidity. The present study reports a double-blind, prospective, randomized clinical trial testing the efficacy of a calcium phosphate mouth rinse (Caphosol) with fluoride treatments vs a standard regimen of fluoride rinsing and placebo tray treatments in 95 patients undergoing hematopoietic stem cell transplantation (HSCT). The days and severity of mucositis were prospectively evaluated. There were statistically significant decreases in days of mucositis (3.72 vs 7.22 P=0.001), duration of pain (2.86 vs 7.67, P=0.0001), dose of morphine (34.54 mg vs 122.78 mg), days of morphine (1.26 vs 4.02, P=0.0001) and days to the onset of engraftment ANC (absolute neurotrophil count)>200 mm(3) (11.12 vs 12.56) in the Caphosol and fluoride treatment group vs fluoride-rinse group, respectively. Caphosol, a neutral, supersaturated, Ca(2+)/PO(4)(3-) mouth rinse, used in combination with topical fluoride treatments, is superior to fluoride rinse alone in reducing the frequency, intensity and duration of oral mucositis in patients undergoing HSCT.

Abstract
Amifostine (Ethyol), an inorganic thiophosphate, is a selective broad-spectrum cytoprotector of normal tissues that provides cytoprotection against ionizing radiation and chemotherapeutic agents, thus preserving the efficacy of radiotherapy and chemotherapy. This review summarizes the preclinical data and clinical experience with amifostine, and provides insight into future clinical directions. Amifostine, an inactive pro-drug, is transformed to an active thiol after dephosphorylation by alkaline phosphatase found in the normal endothelium. The absence of alkaline phosphatase in the tumoral endothelium and stromal components, and the hypovascularity and acidity of the tumor environment, may explain its cytoprotective selectivity. The cytoprotective mechanism of amifostine is complicated, involving free radical scavenging, DNA protection and repair acceleration, and induction of cellular hypoxia. Intravenous administration of amifostine 740-900 mg/m(2) before chemotherapy and 250-350 mg/m(2) before each radiotherapy fraction are widely used regimens. The US Food and Drug Administration has approved the use of amifostine as a cytoprotector for cisplatin chemotherapy and for radiation-induced xerostomia. Ongoing trials are being conducted to determine the efficacy of amifostine in reducing radiation-induced mucositis and other toxicities. Novel schedules and routes of administration are under investigation, and may further simplify the use of amifostine and considerably broaden its applications.

Abstract
Patients receiving high-dose preparation for stem cell transplantation are at risk for organ dysfunction (OD). Signs of early OD include hypoxia, mental status changes, and liver dysfunction. These early signs have not been correlated with potential cytokine mediators. We compared plasma concentrations of IL-6, TNF-alpha, and IL-10 in OD patients and controls. Cytokines were measured before preparation, 5 days before OD, day of OD, and 5 days after OD. TNF-alpha and IL-10 were not measurable prior to preparation. IL-10 was more likely to be measurable in OD patients than in controls 5 days prior to onset of OD (P = 0.039), on the day of OD (P = 0.023), and 5 days later (P < 0.0001). TNF-alpha was more likely to be measurable only on the day of OD (P = 0.0035). IL-6 was significantly elevated in OD patients at all time points. Patients who had measurable IL-6 on admission were 5.1 times more likely to develop OD (95% CI = 1.4-17.9; P = 0.011). Five days prior to OD for each 100 pg/ml increase in IL-6, patients were 2.75 times more likely to develop OD (95% CI = 1.3-5.8; P = 0.0087). The early elevation of IL-6 in patients who develop OD may help identify a high risk group where preventive therapies can be evaluated.
