SummaryCurrent knowledge of the haematological and onco-haematological complications of type 1 Gaucher disease has been reviewed with the aim of identifying best clinical practice for treatment and disease management. It was concluded that: (i) Awareness of typical patterns of cytopenia can help clinicians distinguish haematological co-morbidities. (ii) Red blood cell studies and complete iron metabolism evaluation at baseline are recommended. (iii) Haemoglobin levels defining anaemia should be raised and used in Gaucher disease treatment and monitoring. (iv) Surgeons should be aware of potential bleeding complications during surgery in Gaucher patients. The higher incidence of multiple myeloma in Gaucher disease suggests that Gaucher patients should have their immunoglobulin profile determined at diagnosis and monitored every 2 years (patients <50 years) or every year (patients >50 years). If monoclonal gammopathy of undetermined significance (MGUS) is found, general MGUS guidelines should be followed. Future studies should focus on the utility of early treatment to prevent immunoglobulin abnormalities and multiple myeloma.

Gaucher Disease type 1 (GD1) is a lysosomal disorder that affects many systems. Therapy improves the principal manifestations of the condition and, as a consequence, many patients show a modified phenotype which reflects manifestations of their disease that are refractory to treatment. More generally, it is increasingly recognised that information as to how a patient feels and functions [obtained by patient- reported outcome measurements (PROMs)] is critical to any comprehensive evaluation of treatment. A new set of management goals for GD1 in which both trends are reflected is needed. To this end, a modified Delphi procedure among 25 experts was performed. Based on a literature review and with input from patients, 65 potential goals were formulated as statements. Consensus was considered to be reached when ≥75% of the participants agreed to include that specific statement in the management goals. There was agreement on 42 statements. In addition to the traditional goals concerning haematological, visceral and bone manifestations, improvement in quality of life, fatigue and social participation, as well as early detection of long-term complications or associated diseases were included. When applying this set of goals in medical practice, the clinical status of the individual patient should be taken into account.

Objective: HYPER-CVAD is an intensive treatment protocol of short duration, for ALL and other lymphoid neoplasms. It is consisted of 8 alternating cycles (parts A and B): in part A (cycles 1, 3, 5, 7) fractionated doses of cyclophosphamide, vincristine, doxorubicin and dexamethazone are administrated, while in part B (cycles 2, 4, 6, 8) high doses of methotrexate and aracytin. The two first cycles compose the induction therapy, while the next 6 cycles constitute the consolidation therapy, followed by two years of maintenance therapy. Protection of CNS is achieved with intradorsal injections, whereas in Ph+ ALL patients, imatinib is also administered. The aim of this study was the clinical evaluation of MRD detection in adult patients with ALL, during chemotherapy with HYPER-CVAD. Patients/Methods: During the period 1999–2008, 30 patients were hospitalized in our hospital for ALL and were treated with HYPER-CVAD therapeutic protocol. Among them, 14/30 (46,7%) were males and 16/30 (53,3%) females (median age 43,5 years, range 16–70). Median follow-up time was 12,8 months (range 0,5–100). ALL of T-origin had 8/30 patients and of B-origin, 22/30 (1 B1-EGIL/pro-B, 17 B2-EGIL/B-common, 4 B3-EGIL/pre-B). Caryotypic analysis and FISH was done in all patients (7/30 bcr/abl+). According to classical prognostic markers of ALL: 21/30 were classified as high, 4/30 as medium and 5/30 low risk, respectively. MRD presence was detected in bone marrow samples, with flow cytometric panels, at three particular treatment time-points: completion of induction therapy (T1), completion of consolidation therapy (T2) and at the end of maintenance therapy (T3). Overall survival (OS) and disease free survival (DFS) were investigated, especially in relation to the influence of MRD presence in (OS) and (DFS), respectively. For statistical analysis, Kaplan-Meier was used. Results: At treatment time-point (T1), MRD was detected in 10/28 (35,7%) patients, at time-point (T2) in 7/23 (30,4%) and at treatment-point (T3) in 9/17 (52,94%). The influence of MRD detection in (OS) was statistically significant (p&lt;0,05) at (T2) and (T3), while in (DFS) the detection of MRD presence in any of the standardized treatment time-points resulted in decreased DFS (T1/p&lt;0,05, T2 and T3/p&lt;0,001). Conclusions: Our results suggest that MRD detection during therapy of adult ALL is a negative prognostic indicator for (OS) and (DFS), the independency of which has to be confirmed after prolonged follow-up time and increased number of cases.
