Oral complications of cancer therapy often have systemic consequences. Pain and discomfort are common and can lower intake of fluid and nutrients, which in severe cases can lead to dehydration and malnutrition, requiring hospitalization. Oral infections are frequent accompaniments of cancer treatment. Herpes simplex virus is the most common symptomatic oral viral infection, and, in latently infected patients the virus is frequently reactivated after cytoreductive therapy. Viral (infectious) oral mucositis is often indistinguishable from noninfectious mucositis. Bacterial infections are less commonly observed today, perhaps because of the routine use of empiric broad-spectrum antibiotics; however, many episodes of septicemia in neutropenic patients apparently originate from oral microorganisms. Fungal infections are frequent and are usually due to Candida species. Spread to the esophagus or systemic dissemination can occur. Noninfectious oral mucositis can be used as a marker of toxic effects in other organs, especially hepatic veno-occlusive disease. In bone marrow transplant patients with mucositis, hepatic veno-occlusive disease is six times more frequent than in such patients without mucositis.

Autologous bone marrow transplantation, using unpurged cryopreserved autologous marrow, was performed on ten adult patients with acute myeloid leukaemia in remission. Seven patients were in first chemotherapy-induced remission of their disease, while three were in later remission. Patients ages ranged from 24 to 52 years, with a median of 38.5 years. Conditioning therapy consisted of oral busulphan 16 mg/kg over four days and intravenous cyclophosphamide 60 mg/kg on two days. Bone marrow cells were thawed and infused two days later. All patients showed signs of marrow engraftment, however this was delayed in comparison with patients receiving allogeneic transplants. All patients developed fever requiring antibiotic therapy and one patient died of overwhelming sepsis. Another patient died of hepatic veno-occlusive disease two months after transplant. Serious, but non-fatal, hepatic complications occurred in two other patients. One patient, transplanted in third remission, relapsed 16 months post-autograft. No other relapses have been seen, with one second remission patient remaining leukaemia-free at 24 months, and six first remission patients in continuing remission 11 to 23 (median 20) months post transplant. These encouraging results require confirmation in a randomised clinical trial comparing autologous marrow transplantation versus standard chemotherapy.

Preparative regimens containing busulfan (BU) followed by allogeneic bone marrow transplantation (BMT) were used in 27 consecutive patients with myelodysplastic syndromes (MDS). The median age was 33 years (range, 4 to 54). Ten were female and 17 male. Sixteen patients had primary MDS, 11 other patients had antecedent hematologic diseases or developed MDS after cytotoxic and/or radiation therapy. Six patients had leukemic transformation and received antileukemic therapy before BMT. Pre-BMT cytogenetic studies showed complex chromosomal abnormalities in 13 patients, a simple abnormality in 5 patients, and normal chromosome in 8 patients. Three BU-based preparative regimens were used: 1 patient received BU 4 mg/kg orally (PO) daily for 4 days and cyclophosphamide (CY) 50 mg/kg intravenously (IV) daily for 4 days (BUCY-4); 24 patients received BU 4 mg/kg PO daily for 4 days, cytosine arabinoside (ara-C) 2 g/m2 IV every 12 hours for 4 doses, and CY 60 mg/kg IV daily for 2 days (BAC); and 2 patients with preceding Fanconi anemia received BU 2 mg/kg PO daily for 4 days followed by total lymphoid irradiation of 5 Gy. Seventeen of 27 patients are alive with no evidence of disease. Ten patients have died: 2 from hepatic veno-occlusive disease, 3 from sepsis, 1 from a cerebral bleed, 1 from a massive gastrointestinal (GI) bleed associated with acute graft-versus-host disease, 1 from hemolytic uremic syndrome with adult respiratory distress syndrome, 1 from bronchiolitis obliterans, and the only patient who did not engraft died from acute myeloid leukemia. Regimen-related toxicities (RRT) include GI tract (diarrhea, 14; stomatitis, 11), liver (9), cardiac (1), and skin (5). Patients who received a genotypically matched marrow graft had a significantly better disease-free survival (DFS) than patients who received a nongenotypic marrow graft (P = .02). The Kaplan-Meier analysis projects an overall DFS of 56% +/- 13% and 78% +/- 10% for patients who received a genotypically matched marrow graft. With the exception of a child who did not engraft, there was no relapse of MDS or leukemia. Excellent DFS, acceptable RRT, and the ease of administration are advantages of this regimen.

Despite adjuvant chemotherapy the prognosis of patients with breast cancer and a high number of involved axillary lymph nodes is very poor. The aim of the present study was to evaluate the efficacy of high-dose chemotherapy with autologous bone marrow support in patients with seven or more involved axillary lymph nodes. Nineteen patients underwent four courses of standard adjuvant chemotherapy, followed by high-dose busulphan/cyclophosphamide chemotherapy with autologous bone marrow support. The median age was 41.4 years and the median number of involved lymph nodes 11. Mucositis WHO grade > or = 3 was observed in 15 patients and 18 patients suffered febrile neutropenia. Transplant-related mortality was encountered in two patients, due to hepatic veno-occlusive disease and sepsis complicated by multi-organ failure, respectively. After a median follow-up period of 1490 days (range 582-2024 days) from diagnosis, nine patients have relapsed and the overall event-free survival (EFS) is 42% (95% CI 19-65%). The median EFS is 487 days. High-dose treatment with BuCy2 in high-risk breast cancer patients is a toxic regimen and does not seem to improve disease-free survival.

Haemophagocytic lymphohistiocytosis (HLH) is an autosomal recessive disease with histiocytic and lymphocytic infiltrations in multiple organs. Cure seems possible only by allogeneic bone marrow transplantation (BMT), but matched sibling donors (MSD) are restricted and high mortality rates are associated with BMT from unrelated donors (URD). We report on 12 consecutive HLH patients with an improved outcome following URD transplants. Eight patients received BMT from URD, four from MSD. Five patients had signs of active HLH at the time of BMT. The conditioning regimen consisted of 20 mg/kg busulphan, 60 mg/kg VP-16 and 120 mg/kg cyclophosphamide and, in case of URD, 90 mg/kg antithymocyte globulin. The doses of busulphan and VP-16 were reduced during the programme to 16 mg/kg and 30 mg/kg, respectively. Using a fivefold graft-versus-host disease (GVHD) prophylaxis, GVHD was absent or mild in 10, and moderate or severe in two patients undergoing unrelated transplants. One patient with URD experienced graft failure and was retransplanted on day 37. Major toxicities were hepatic veno-occlusive disease in five, capillary leak syndrome in two, pneumonia in three, sepsis in one, severe mucositis in one and seizures in two patients. All patients are alive without HLH after a median follow-up of 24.5 months. One patient has chronic GVHD, another patient has severe retardation. Three patients show slight to moderate development delay. These results indicate that in HLH, BMT from matched unrelated donors should be performed. Incomplete resolution of disease activity need not impede a successful outcome.

Development of jaundice is an ominous prognostic sign, whether it occurs early or late in the months following hematopoietic cell transplant. In the first weeks after transplant, the dominant causes of liver injury are Sinusoidal Obstruction Syndrome (toxic damage resulting from myeloablative conditioning regimens) and cholangitis lenta (cholestasis of sepsis). Later after transplant, cholestasis is more commonly caused by acute graft-vs.-host disease and drugs. Hepatic infections have become uncommon because of the use of prophylactic anti-fungal and anti-viral drugs. Treatment of severe liver dysfunction is often futile in this setting, but prevention of liver injury is feasible. Hepatic sinusoidal injury can be prevented by avoiding sinusoidal toxins as part of conditioning therapy in patients at high-risk. Cholestatic liver damage can be minimized by prophylactic use of ursodiol and by careful drug monitoring. Anti-microbial drugs will prevent most fungal liver infections and viral hepatitis caused by herpesviruses and hepatitis B virus.

High-dose chemotherapy with autologous SCT has become standard of care for patients with relapsed aggressive non-Hodgkin's lymphoma (NHL). To improve safety and efficacy of this treatment, new conditioning regimens are being developed. We retrospectively reviewed clinical data of patients with relapsed NHL treated at our institution with i.v. BU and CY (BU/CY) as conditioning regimen for autologous SCT between January 2000 and April 2005. We identified 43 patients (24 men, 19 women, median age 50) with diffuse large B-cell lymphoma (n=28), follicular lymphoma (n=8), mantle cell lymphoma (n=4) and peripheral T-cell lymphoma (n=3). Following salvage chemotherapy, there were 26 complete responses, 13 partial responses and 4 stable diseases. Median time to neutrophil and platelet recovery was 11 and 13.5 days, respectively. Treatment-related toxicities included nausea/vomiting, diarrhea and mucositis. The 100-day mortality was 9%: sepsis (n=1), pneumonia (n=1) and hepatic veno-occlusive disease (n=2). Twenty-one patients were followed until death and twenty-one surviving patients were followed for a median of 29 months (range 0.4-76). Three-year estimates of event-free survival, progression-free survival and overall survival were 35, 39 and 43%, respectively. We conclude that i.v. BU/CY is a safe and effective conditioning regimen for autologous SCT in relapsed NHL.

Abdominal venous thrombosis may present as splanchnic venous thrombosis (SVT) (occlusion of portal, splenic, superior or inferior mesenteric veins) or Budd- Chiari Syndrome (BCS) (thrombosis of inferior vena cava and/or hepatic veins). The aim of this review is to report the scanty data available for SVT in the South Mediterranean area. In one Egyptian study, the possible circumstantial risk factors for portal vein thrombosis (PVT) were found in 30% of cases: 19% neonatal sepsis, 8.7% umbilical catheterization, 6% severe gastroenteritis and dehydration. Another Egyptian study concluded that hereditary thrombophilia was common in children with PVT (62.5%), the commonest being factor V Leiden mutation (FVL) (30%). Concurrence of more than one hereditary thrombophilia was not uncommon (12.5%). The first international publication on hepatic veno-occlusive disease (VOD) in Egypt was in 1965 in children who rapidly develop abdominal distention with ascites and hepatomegaly. This disease was more frequent in malnourished children coming from rural areas; infusions given at home may contain noxious substances that were hepatotoxic and infections might play a role. VOD of childhood is rarely seen nowadays. Data from South Mediterranean area are deficient and this may be attributable to reporting in local medical journals that are difficult to access. Medical societies concerned with this topic could help distribute this information.

Hepatic veno-occlusive disease (VOD) is a frequent and severe complication of hematopoietic stem cell transplantation (HSCT) affecting 9.6-17.3 % of cases. 200 HSCT, performed between January 1995 and March 2013 in our Paediatric HSCT Centre in Trieste, were retrospectively analysed to evaluate the frequency of VOD and to identify the associated risk factors. The frequency of VOD according to the Seattle criteria was 17 %, within the range reported in literature. The mortality rate was 37.5 % (75 out of 200 transplantations) in the general population and 73.5 % (25 out of 34) in VOD patients (p < 0.05). Veno-occlusive disease significantly decreased from 38 % (1995-2000) to 8 % (2007-2013) p < 0.05. Univariate and multivariate analyses identified sepsis and pre-transplant ferritin levels above 1000 ng/ml as two significant risk factors for VOD, while the use of tacrolimus appeared to be associated with a lower VOD risk. Veno-occlusive disease still remains an important cause of transplant-related mortality even if it appears to have decreased over the last few years.

Hematopoietic stem cell transplantation is a widely used therapeutic modality for many, mainly malignant, diseases. Toxicities of this procedure include acute and chronic renal dysfunction. Acute renal failure, generally reversible is due to acute tubular necrosis (tumor lysis syndrome, marrow-infusion toxicity, sepsis, nephrotoxins), hepatic veno-occlusive disease or acute graft-versus-host disease. Chronic renal failure is often multifactorial, caused by conditioning-associated endothelial cell toxicity (bone marrow transplant nephropathy) and calcineurin inhibitors toxicity. Renal pathologic findings are somewhat similar to thrombotic microangiopathy, with sometimes systemic disease. Rare cases of nephrotic syndrome have been described after hematopoietic stem cell transplantation, mainly membranous nephropathy, associated with graft-versus-host disease. Therapeutic options for renal dysfunction after hematopoietic stem cell transplantation are limited but kidney transplantation is possible in case of end-stage renal disease.
