Management of veno-occlusive disease: the multidisciplinary approach to care.

Although it is considered a relatively rare disorder, veno-occlusive disease (VOD) is one of the main causes of overall, non-relapse mortality associated with haematopoietic stem cell transplantation (HSCT). This article, based on the consensus opinion of haemato-oncology nurses, haemato-oncologists and pharmacists from both adult and paediatric services at the VOD International Multi-Disciplinary Advisory Board at the European Society for Blood and Marrow Transplantation (EBMT) meeting, Istanbul, 2015, aims to explore the multidisciplinary approach to care for the management of VOD, with an emphasis on current challenges in this area. The careful monitoring of HSCT patients allows early detection of the symptoms associated with VOD and timely treatment, ultimately improving patient outcomes. As part of a multidisciplinary team, nurses have an essential role to play, from pretransplant assessment to medical management and overall care of the patient. Physicians and pharmacists have a responsibility to facilitate education and training so that nurses can work effectively within that team.

R-ESHAP plus pegfilgrastim as an effective peripheral stem cell mobilization regimen for autologous stem-cell transplantation in patients with relapsed/refractory diffuse large B-cell lymphoma.

Stem cell (SC) mobilization is significantly influenced by the mobilization schedule in patients with lymphoma. We evaluated data from 30 patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) undergoing SC mobilization. All received R-ESHAP plus a single dose of pegfilgrastim. All patients collected ⩾ 2 × 10(6) CD34+cells/kg, 80% of them at least 5 × 10(6) CD34+cells/kg. Adverse effects of the regimen included myelosuppression and neutropenic fever. Herein, our results suggest that R-ESHAP plus pegfilgrastim is a highly effective mobilization strategy in patients affected by DLBCL associated with a low incidence of adverse events.

Efficacy of photopheresis extracorporeal procedure as single treatment for severe chronic GVHD: a case report.

Allogeneic hematopoietic stem cell transplantation is the only potentially curative therapeutic option for many malignant and nonmalignant hematologic disorders. Despite this, several factors unfavorably affect the outcome of this procedure and in particular chronic graft-versus-host disease (cGVHD) remains the principal cause of morbidity after allogeneic transplantation. Here we present our experience regarding a patient affected by extensive chronic GVHD (cGVHD) treated only with extracorporeal photopheresis procedure (ECP) as first line treatment. The patient, presenting an high risk myelodysplastic syndrome (MDS), underwent an allogeneic peripheral stem cells transplantation. About 2 months after transplantation she experienced a hematological and clinical relapse of MDS. After reinduction therapy with azacitidine she obtained a second complete remission. Because of the risk of relapse related to a strong immunosuppressant therapy and the previous infectious complication, we decided to start a treatment with ECP alone for cGVHD. After six procedure the patient obtained a complete resolution of all signs and symptoms of the cGVHD. This experience may support the possibility to use only an immunomodulant treatment like ECP for the cGVHD, reducing the risk of complications of prolonged immunosuppressant treatment.

Plerixafor and Filgrastim XM02 (Tevagastrim) as a first line peripheral blood stem cell mobilisation strategy in patients with multiple myeloma and lymphoma candidated to autologous bone marrow transplantation.

Plerixafor, a CXCR4 antagonist, has shown to be effective in increasing the number of circulating stem cells, even in patients failing a previous mobilisation attempt. Recently a number of non-glycosylated recombinant human granulocyte-colony stimulating factor (G-CSF) has been clinically approved for the same indications as the originator G-CSF for comparable safety and efficacy and their reduced cost. In an attempt to provide a less toxic strategy, 14 patients affected by haematological malignancies (non-Hodgkin's lymphoma = 4, Hodgkin's disease = 2 and multiple myeloma = 8), received the combination of biosimilar filgrastim and plerixafor as a first line mobilising strategy. The median number of circulating CD34+ cells on day 4 was 16 (3-42); Plerixafor was administered to all, but one patient who had already 42 CD34+ cells per µL on day 4. On day 5, after plerixafor administration, the median number of circulating CD34+ cells had raised to 60 per µL (14-138). All the patients underwent leukapheresis and were able to collect a number of CD34+ cells ≥ 2.0 × 10(6) /kg in a median number of procedures of one. Although preliminary, these data show the combination of biosimilar filgrastim and plerixafor is effective and provides a non-toxic approach to mobilise stem cells.

Who should be really considered as a poor mobilizer in the plerixafor era?

Patients with a number of peripheral CD34+ cells ≥20/µL have recently been defined in the literature as "poor mobilizers". We retrospectively reviewed medical records from a total of 248 patients affected by hematological malignancies or solid tumors undergoing peripheral blood stem cell collection following chemotherapy plus G-CSF. On the basis of the CD34+ cell peak in peripheral blood following mobilization therapy, patients were defined as good mobilizers (group A, CD34+ cells ≥20/µL), relative poor mobilizers (group B, CD34+ cells <20 and ≥8/µL) and absolute poor mobilizers (group C, CD34+ cells <8/µL). One hundred and seventy-seven (71%) patients resulted good mobilizers, 35 (14%) patients relative poor mobilizers and 36 (15%) patients absolute poor mobilizers. Target of stem cell collection was ≥2.0×10(6) CD34+cells/kg for each transplantation procedure. All patients in group A, 20 patients in group B (57%) and 1 patient in group C (2.7%) were able to collect ≥2.0×10(6) CD34+cells/kg. The multivariate analysis confirmed that more than three lines of previous chemotherapy and a previous autologous PBSC transplantation negatively affect mobilization of CD34+ cells in peripheral blood. Our data suggest that a number of CD34+ cells ≥20/µL does not always result in a failed stem cell collection and in fact in our patient series more than 70% of the patients defined as poor mobilizers have indeed collected the minimum number of 2.0×10(6) CD34+cells/kg required for a successful transplantation. The use of new agent such as CXCR4 antagonist plerixafor might further improve mobilization efficacy in such patients.

Decreased ERß expression and high cyclin D1 expression may predict early CRC recurrence in high-risk Duke's B and Duke's C stage.

PURPOSE: Despite many known risk factors for the colorectal cancer (CRC) recurrence, significant differences in disease-free survival (DFS) impose the need to look for new explanations. This study aimed to determine the degree of expression of ERα, ERß, PR, Cyclin D1, and Bcl-2 and their association with early CRC relapse. METHODS: This retrospective study included 101 radically operated CRC patients in high-risk Duke's B and Duke's C stage. Tissue samples were retrieved from paraffin blocks and clinical and diagnostic data from medical records obtained during further clinical treatment and follow up. Patients were divided into DFS≤24 months group and DFS≥48 months group. Immunostaining of ERα, ERß, PR, Cyclin D1, and Bcl-2 was performed and analyzed. RESULTS: ERα was not expressed in all patients. ERß moderate expression was present in 25% of all patients, more often in the DFS≥48 group (p=0.001). PR and Bcl-2 showed only moderate expression in 1/5 and 1/3 of the patients, respectively, without significant difference between groups (p=0.145;p=0.566). Cyclin D1 was expressed in the whole sample of patients with strong expression statistically more often in DFS≤24 group (p=0.011) and had 5.2 higher odds of having DFS˂24 months. Moderate expression of ERß was joined with 79.2% smaller odds for shorter DFS. Advanced T stage had 11.3 times higher odds of having DFS˂24 months. CONCLUSION: Early recurrence of CRC in high-risk Duke's B and Duke's C stage relates with reduced ERß expression and the high cyclin D1 expression, so they could be considered independent prognostic factors, especially in patients in advanced T stage.

A single dose of Pegfilgrastim versus daily Filgrastim to evaluate the mobilization and the engraftment of autologous peripheral hematopoietic progenitors in malignant lymphoma patients candidate for high-dose chemotherapy.

Pegfilgrastim has equivalent efficacy to daily G-CSF in enhancing neutrophil recovery after chemotherapy, but conclusive data concerning its use for peripheral blood stem cell (PBSC) mobilization are lacking. From 2003 to 2008 we used high-dose chemotherapy in 64 lymphoma patients. At mobilization chemotherapy (ESHAP) the first 26 patients used unconjugated G-CSF, while the remaining 38 patients received Pegfilgrastim. At the time of harvest 25 patients collected stem cells after the use of G-CSF and 36 in the Peg group. No statistical by significant differences were observed in median peripheral CD34+ cells mobilized (77 µL versus 71 µL) and in collected PBSC (12.3 × 10(6)/kg versus 9.4 × 10(6)/kg p = 0.76). In the PEG group all patients collected the target PBSC with a single apheresis with a greater proportion of "optimal" mobilizers (83% versus 64%; p = 0.05). In conclusion a single dose of Pegfilgrastim could be a valid alternative to unconjugated G-CSF to mobilize PBSC in lymphoma patients.

Nutritional support in stem cell transplantation programs: Results from a multicenter survey of nurses on behalf of the Nurses Group and Transplant Complications Working Party of the European Society for Blood and Marrow Transplantation and the Gruppo Italiano Trapianto di Midollo Osseo.

OBJECTIVES: Malnutrition in patients undergoing hematopoietic stem cell transplant (HSCT) can develop rapidly without appropriate nutritional support and affect morbidity and mortality. Guidance to monitor and manage nutrition status is described within the literature; however, whether this is applied in clinical practice is unclear. METHODS: This paper describes a cross-sectional survey to explore current practice approaches in nutrition support management and adherence to international guidelines. RESULTS: A total of 108 nurses from 108 centers across 16 countries replied to the questionnaire. A significant variation was observed regarding the availability of documents supporting the monitoring and management of nutrition status, application of recommendations, and nutritional practices. DISCUSSION: The findings revealed that country was the most important factor influencing the differences in practice; however, significant differences were also observed based on patient age group (pediatrics vs. adults), department composition (hematology + HSCT unit vs. HSCT unit alone), and availability of nutrition health care professionals. Behavioral differences regarding nutritional practice approaches could be indicative of differences in knowledge or subject awareness, as well as a reflection of diversity across health care system policies. CONCLUSIONS: Guideline dissemination and raising awareness through educational campaigns are suggested approaches to improve health care professionals' knowledge and sensitivity to this important topic.

Health-care professionals' perspective on discussing sexual issues in adult patients after haematopoietic cell transplantation.

The majority of adult patients have sexual concerns after post-haematopoietic cell transplantation. Even so, health-care professionals (HCP) do not routinely discuss these problems. We, therefore, surveyed all the members of the European Society for Blood and Marrow Transplantation to evaluate the barriers and facilitators to discussing sexual issues. The 73-item web-survey was completed by 166 registered nurses (RNs) and 126 medical doctors (MDs). Sixty-eight percent reported that they seldom discussed sexual issues. Younger MDs (p < 0.001) and those who work in non-western European countries (p = 0.003), RNs with probably less sexual education themselves (p = 0.002), MDs and RNs who have limited knowledge about sexual complications (p < 0.001) and MDs and RNs who feel uncomfortable discussing sexual issues (p < 0.001) are all less likely to discuss these matters. The major perceived barriers were that patients might be embarrassed if sexual issues were discussed in the presence of a relative (60% RNs, 67% MDs) and that professionals prefer patients to raise sexual issues themselves (54% RNs, 44% MDs). The most important perceived facilitator was for the patient to initiate discussion (≥ 90% for RNs and MDs). Overall, haematopoietic cell transplantation survivors may not be receiving the support on sexual issues they probably need.
