Management of chronic lymphocytic leukemia: practice guidelines from the Italian Society of Hematology, the Italian Society of Experimental Hematology and the Italian Group for Bone Marrow Transplantation.

The Italian Society of Hematology (SIE) and two affiliate societies (SIES and GITMO) commissioned a project to develop clinical practice guidelines for the treatment of chronic lymphocytic leukemia (CLL). METHODS: Key questions in the management of patients with CLL were formulated by an Advisory Committee and approved by an Expert Panel of eight senior hematologists. After a systematic review of the literature, recommendations for disease-specific and supportive therapies were formulated and graded according to the supporting evidence. Explicit consensus methods were used for providing recommendations for questions with incomplete or potentially biased evidence. RESULTS: It is recommended that therapy is commenced in patients with CLL when at least one of the following are present: B-symptoms, progressive/obstructive lymphadenopathy or organomegaly, rapid lymphocyte doubling time, anemia or thrombocytopenia (of new onset, worsening or steroid-resistant). It is recommended that patients without co-morbidity should receive fludarabine plus cyclophosphamide, whereas elderly patients with co-morbidity should receive oral chlorambucil. Younger patients with unfavorable biological risk factors should be considered for high-dose chemotherapy and autologous or allogeneic stem cell transplantation within approved clinical trials. Patients either relapsing rapidly after, or non-responsive to, first-line chlorambucil should receive fludarabine-containing regimens. Patients either relapsing soon after or not responding to fludarabine-based chemotherapy should be considered for schedules including non-cross-reactive agents, such as alemtuzumab, possibly followed by high-dose chemotherapy and autologous transplantation in the context of a clinical trial or by allogeneic stem cell transplantation. CONCLUSIONS: We describe the results of a systematic literature review and an explicit approach to consensus techniques which resulted in recommendations for the key therapeutic decisions in patients with CLL

Consensus conference on the management of tumor lysis syndrome.

Tumor lysis syndrome is a potentially life threatening complication of massive cellular lysis in cancers. Identification of high-risk patients and early recognition of the syndrome is crucial in the institution of appropriate treatments. Drugs that act on the metabolic pathway of uric acid to allantoin, like allopurinol or rasburicase, are effective for prophylaxis and treatment of tumor lysis syndrome. Sound recommendations should regulate diagnosis and drug application in the clinical setting. The current article reports the recommendations on the management of tumor lysis syndrome that were issued during a Consensus Conference project, and which were endorsed by the Italian Society of Hematology (SIE), the Italian Association of Pediatric Oncologists (AIEOP) and the Italian Society of Medical Oncology (AIOM). Current concepts on the pathophysiology, clinical features, and therapy of tumor lysis syndrome were evaluated by a Panel of 8 experts. A consensus was then developed for statements regarding key questions on tumor lysis syndrome management selected according to the criterion of relevance by group discussion. Hydration and rasburicase should be administered to adult cancer patients who are candidates for tumor-specific therapy and who carry a high risk of tumor lysis syndrome. Cancer patients with a low-risk of tumor lysis syndrome should instead receive hydration along with oral allopurinol. Hydration and rasburicase should also be administered to patients with clinical tumor lysis syndrome and to adults and high-risk children who develop laboratory tumor lysis syndrome. In conclusion, the Panel recommended rasburicase for tumor lysis syndrome prophylaxis in selected patients based on the drug efficacy profile. Methodologically rigorous studies are needed to clarify its cost-effectiveness profile

Management of nodal diffuse large B-cell lymphomas: practice guidelines from the Italian Society of Hematology, the Italian Society of Experimental Hematology and the Italian Group for Bone Marrow Transplantation

The Italian Society of Hematology (SIE) and two affiliate societies (SIES and GITMO) commissioned a project to develop clinical practice guidelines for the treatment of nodal diffuse large B-cell non Hodgkin lymphomas (DLBCL). Key questions clinically relevant to the management of patients with nodal DLBCL were formulated by an Advisory Committee (AC) and approved by an Expert Panel (EP) composed of eight senior hematologists. After a comprehensive and systematic literature review, the EP formulated therapy recommendations and graded them according to the supporting evidence. An explicit approach to consensus methodologies was used for evidence interpretation and for producing recommendations in the absence of strong evidence. The EP formulated recommendations on which first-line therapy to choose in patients with nodal DLBCL. Patients of all ages, with stage I-II disease and no adverse prognostic factors should receive abbreviated chemotherapy with an anthracycline-containing regimen plus involved field radiotherapy (35-40 Gy). Patients with stage I-II disease and at least one adverse prognostic factor, or with stage III-IV disease, should receive frontline chemoimmunotherapy with CHOP, CHOP-like or third-generation chemotherapy plus rituximab. Recommendations on stem cell transplantation and on which therapy to adopt for refractory or relapsed patients were also formulated

Management of nodal indolent (non marginal-zone) non-Hodgkin's lymphomas: practice guidelines from the Italian Society of Hematology, Italian Society of Experimental Hematology and Italian Group for Bone Marrow Transplantation

The Italian Society of Hematology (SIE) and the two affiliated societies (SIES and GITMO) commissioned a project to develop clinical practice guidelines for the treatment of nodal indolent non-Hodgkin's lymphomas (NHL). Key questions clinically relevant to the management of patients with nodal indolent NHL were formulated by an Advisory Committee and approved by an Expert Panel composed of eight senior hematologists. After a comprehensive, systematic review of the literature, the Expert Panel formulated therapy recommendations and graded them according to the supporting evidence. An explicit approach to consensus methodologies was used for evidence interpretation and for providing recommendations based on poor evidence. The Expert Panel formulated recommendations on when to start a lymphoma-specific therapy, which first-line therapy to choose and which therapy to adopt for patients with relapsed, refractory and transformed disease. Treatment deferral was recommended for patients with stage III-IV disease without systemic symptoms, high tumor burden, extranodal disease, cytopenia due to marrow involvement, leukemic phase, serous effusion and high lactate dehydrogenase levels. Patients with stage I-II disease and a low tumor burden should receive frontline external involved-field radiotherapy, while patients with a high tumor burden or a severe prognostic score should receive front-line chemotherapy plus involved-field radiotherapy. Younger patients with stage III-IV disease should receive front-line therapy with anthracycline- or fludarabine-based regimens combined with rituximab, while older patients who are candidates for treatment should receive single-agent alkylating therapy. By using a systematic literature review and an explicit approach to consensus among experts, recommendations for the key therapeutic decisions in patients with nodal indolent NHL are provided

SIE-SIES-GITMO guidelines for the management of adult peripheral T- and NK-cell lymphomas, excluding mature T-cell leukaemias

Background: In order to promote widespread adoption of appropriate clinical practice, the Italian Society of Hematology (SIE), and the affiliate societies SIES (Italian Society of Experimental Hematology) and GITMO (Italian Group for Bone Marrow Transplantation) established to produce guidelines in the most relevant hematological areas. In this article, we report the recommendations for management of T/NK-cell lymphomas, excluding mature T-cell leukaemias. Design: By using the Grades of Recommendations, Assessment, Development and Evaluation (GRADE) system, we produced evidence-based recommendations for the key clinical questions that needed to be addressed by a critical appraisal of evidence. The consensus methodology was applied to evidence-orphan issues. Results: Six courses of cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) or cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone (CHOEP) chemotherapy were recommended for first-line therapy of patients with nodal, intestinal or hepatosplenic T-cell lymphomas (evidence: low; recommendation: do, weak). Except for ALK+ anaplastic large-cell lymphoma and elderly unfit patients, consolidation with high-dose chemotherapy was recommended (evidence: low; recommendation: do, weak). 50 Gy radiotherapy was the recommended first-line therapy for localized extranodal T/NK-cell lymphoma nasal type (evidence: low; recommendation: do, strong), while L-asparaginase-containing chemotherapy regimens were recommended for patients with systemic disease (evidence: very low; recommendation: do, strong). Conclusion: In adult T/NK-cell lymphomas, GRADE methodology was applicable to a limited number of key therapeutic issues. For the remaining key issues, due to lack of appraisable evidence, recommendations was based on consensus methodology
