MACOP-B chemotherapy for the treatment of high grade and intermediate grade non Hodgkin's lymphoma.
1990
Between Nov. 1985 and Nov. 1988, sixty-three patients with high grade malignant (hg) and intermediate grade malignant (img) Non Hodgkin's Lymphoma (NHL) were treated with MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone and bleomycin). Thirty-seven patients received MACOP-B as an upfront treatment modality, whereas twenty-six patients had relapsed disease and received MACOP-B as a salvage protocol. Four weeks after termination of therapy, 75% of patients with de novo NHL and 72% of the patients with relapsed NHL were in complete remission (CR). In the group of newly diagnosed NHL, 22% achieved partial remission (PR) and 3% no change (NC), whereas in the group wi…
Primary gastrointestinal involvement in non-Hodgkin's lymphomas.
1987
This paper reviews primary gastrointestinal non-Hodgkin's lymphoma (GI-NHL). Every aspect of the topic is discussed though special attention is paid to histopathology and instrumental diagnosis as essential factors to stage the lymphoma and to determine an adequate therapy. Data from the most important works on the subject together with the results of our recent study of 40 primary GI-NHL are reported. Diverse findings by various authors are intentionally compared in a manner to present the work to the reader in the most critical way while trying to give an objective explanation of the different results on the basis of our own experience.
Cytokines in the pathophysiology and treatment of chronic B-cell malignancies
1995
Chronic B-cell malignancies are characterized by accumulation of transformed B cells of low proliferative index in lymphatic and extralymphatic tissues. Cytokines do not appear to play a role in the primary step of transformation. However, proliferation as well as inhibition of apoptosis of malignant B cells can readily be explained by cytokine effects. Clinical trials of interferons (IFN) and interleukin-2 alone or in combination have been performed in patients with hairy cell leukemia (HCL), CLL, and low- and intermediate-grade non-Hodgkin's lymphoma. While IFN alpha became standard therapy of HCL, responses in other entities were variable, ranging from 0 to 70% in selected populations. C…
Splenic marginal zone lymphoma.
2002
Splenic marginal zone lymphoma (SMZL) is a specific low-grade small B-cell lymphoma that is incorporated in the World Health Organization classification. Characteristic features are splenomegaly, moderate lymphocytosis with villous morphology, intrasinusoidal pattern of involvement of various organs, especially bone marrow, and relative indolent course. Tumor progression with increase of blastic forms and aggressive behavior are observed in a minority of patients. Molecular and cytogenetic studies have shown heterogeneous results probably because of the lack of standardized diagnostic criteria. To date, no definitive therapy has been established. Therapeutic options include treatment absten…
Phenotypic APC resistance as a marker of hypercoagulability in primitive cerebral lymphoma
2005
Thrombosis is the most frequent complication and the second cause of death in patients with malignant disease. Primary central nervous system non-Hodgkin's lymphoma represents a rare pathology. Resistance to APC is usually linked to a factor V (FV) gene mutation changing an Arg 506 to a Gln in the APC cleavage site.In our study, we aimed at investigating the presence of activated protein C resistance (APC-r) and other markers of hypercoagulability in 25 selected patients with a diagnosis of primitive cerebral lymphoma who had suffered from an ischemic episode of TIA and/or stroke.25 selected patients with a diagnosis of primitive cerebral lymphoma and 50 healthy subjects acted as control gr…
Genomic Abnormalities Acquired in the Blastic Transformation of Splenic Marginal Zone B-cell Lymphoma
2003
Among 20 cases of typical splenic marginal zone lymphoma (SMZL), two cases had blastic transformation. The genetic mechanisms underlying the morphologic transformation were investigated by comparing genetic changes in initial and blastic phases. A complex karyotype including trisomy of 3q and genomic gain of 17q22-q24 was seen in both cases at diagnosis. However, the extra copy of 3q was lost during the transformation process in both tumors. Additionally, the Karpas 1718 cell line, which was derived from a patient with transformed SMZL and carried a trisomy of 3q, also evidenced the spontaneous loss of the extra 3q during the culturing process. Other acquired abnormalities observed exclusiv…
Host-related factors and cancer: Malnutrition and non-Hodgkin lymphoma
2022
Assessment of host-related factors is a crucial aspect in the comprehensive management of cancer patients. A distinct nutritional disturbance linked to cancer has been recognized to be associated with negative outcomes. However, compared to solid tumors, only a limited number of studies have looked specifically at nutritional issues in the field of lymphoma. The aim of this review is to integrate the current knowledge on interactions between malnutrition and lymphoma and address most relevant and pertinent questions. We first provide a literature review on the mutual biological relationship between malnutrition and lymphoma. Next, we explore the overlap between malnutrition, sarcopenia, cac…
Gonadotropin-releasing hormone agonist for the prevention of chemotherapy-induced ovarian failure in patients with lymphoma: 1-year follow-up of a pr…
2013
PURPOSE To assess the efficacy of gonadotropin-releasing hormone agonist (GnRHa) in preventing chemotherapy-induced ovarian failure in patients treated for Hodgkin or non-Hodgkin lymphoma within the setting of a multicenter, randomized, prospective trial. PATIENTS AND METHODS Patients age 18 to 45 years were randomly assigned to receive either the GnRHa triptorelin plus norethisterone (GnRHa group) or norethisterone alone (control group) concomitantly with alkylating agents containing chemotherapy. The primary end point was the premature ovarian failure (POF) rate (follicle-stimulating hormone [FSH] ≥ 40 IU/L) after 1 year of follow-up. Results Eighty-four of 129 randomly assigned patients …
Incidence, Medical Resource Utilisation and Costs of Hyperuricemia and Tumour Lysis Syndrome in Patients with Acute Leukaemia and Non-Hodgkin's Lymph…
2003
Hyperuricemia (HU) and tumour lysis syndrome (TLS) are complications of acute leukaemia and non-Hodgkin lymphoma (NHL) leading to increased morbidity and mortality. The objective of this study was to define incidence and calculate health care cost associated with HU and TLS. 788 acute leukaemia and NHL patients from Belgium, The Netherlands, Spain and UK were screened retrospectively for HU and TLS. Resource use related to HU and TLS was recorded and costs were calculated applying local unit costs. Results showed that HU occurred in 18.9% of patients, and 27.8% of them fulfilled TLS criteria. The cost of HU without TLS was 672 euros (SE 181), the cost of TLS 7,342 euros (SE 1,412). TLS requ…
Prognostic assessment and treatment of primary gastric lymphomas: how endoscopic ultrasonography can help in tailoring patient management.
2013
Endoscopic ultrasonography (EUS) has recently gained a pivotal role in the management of gastric lymphomas, especially in the diagnostic workup. Its accuracy and reliability have overcome those of other imaging techniques, such that it represents an invaluable tool for the management of gastric lymphomas. Although this technique is operator dependent, its application in large series has proved its reliability. Thus, it has generally been considered a useful tool for providing information crucial in deciding the treatment program, especially for mucosa-associated lymphoid tissue (MALT) lymphomas, for which EUS can provide an accurate evaluation of disease extension and treatment response pro…
