To study prognostic factors of progression/relapse, data concerning 225 children enrolled between 1987 and 1997 in Berlin-Frankfurt-Münster, Société Française d'Oncologie Pédiatrique and United Kingdom Children's Cancer Study Group prospective studies for the treatment of anaplastic large cell lymphoma (ALCL) were merged. Median follow-up was 9.3 years. Five-year overall survival and event-free survival of the whole population was 81% (95% confidence interval, 76%-86%) and 69% (63%-74%), respectively. B symptoms, mediastinal involvement, skin lesions, visceral involvement, St Jude stage 3-4, Ann Arbor stage 3-4, and elevated lactate dehydrogenase increased the risk of progression/relapse in the univariate analysis. In the multivariate analysis, 3 factors remained significant: mediastinal involvement (relative risk [RR] = 2.1 [1.2-3.5]), visceral involvement defined as lung, liver, or spleen involvement (RR = 2.1 [1.3-3.6]), and skin lesions (RR = 1.9 [1.1-3.2]). Five-year progression-free survival (PFS) of the 81 patients with none of these risk factors was 89% [82%-96%], contrasting with a 5-year PFS of 61% [53%-69%] in the 144 patients with at least 1 risk factor (RR = 4.4 [2.2-8.9; P < .001). In conclusion, 3 factors associated with an increased risk of failure in childhood ALCL have been defined: mediastinal involvement, visceral involvement, and skin lesions.

    • "A few studies have systematically analyzed the outcomes of therapeutic approaches for NPM-ALK+ ALCL, and, not unexpectedly, most of these studies focused on pediatric patients [6-13]. Patients usually show an initial favorable response to CHOP; however, 30-40% of the patients in these studies had multiple relapses and disease/therapy-associated death remains a common event [7, 12].

    ABSTRACT: NPM-ALK⁺ T-cell anaplastic large-cell lymphoma (ALCL) is an aggressive type of cancer. Standard treatment of NPM-ALK⁺ ALCL is CHOP polychemotherapy. Although patients initially respond favorably to CHOP, resistance, relapse, and death frequently occur. Recently, selective targeting of ALK has emerged as an alternative therapeutic strategy. ASP3026 is a second-generation ALK inhibitor that can overcome crizotinib resistance in non-small cell lung cancer, and is currently being evaluated in clinical trials of patients with ALK⁺ solid tumors. However, NPM-ALK⁺ ALCL patients are not included in these trials. We studied the effects of ASP3026 on NPM-ALK⁺ ALCL cell lines in vitro and on systemic lymphoma growth in vivo. ASP3026 decreased the viability, proliferation, and colony formation, as well as induced apoptotic cell death of NPM-ALK⁺ ALCL cells. In addition, ASP3026 significantly reduced the proliferation of 293T cells transfected with NPM-ALK mutants that are resistant to crizotinib and downregulated tyrosine phosphorylation of these mutants. Moreover, ASP3026 abrogated systemic NPM-ALK⁺ ALCL growth in mice. Importantly, the survival of ASP3026-treated mice was superior to that of control and CHOP-treated mice. Our data suggest that ASP3026 is an effective treatment for NPM-ALK⁺ ALCL, and support the enrollment of patients with this lymphoma in the ongoing clinical trials.

    • "The standard treatment for pediatric and adolescent ALCL is still under investigation, and varying chemotherapy strategies have been used in different studies with similar success rates.39–41 The European Intergroup for Childhood Non-Hodgkin Lymphoma reported 5-year overall survival and event-free survival of 81% and 69%, respectively (various treatment schedules were used, which included methotrexate, cyclophosphamide, ifosfamide, doxorubicin, and etoposide).41 Despite the varying protocols, ALCL in pediatric and adolescent patients still has a relapse rate of 25%–30%.

    ABSTRACT: Despite the relative success of chemotherapy for Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL), novel therapeutic agents are needed for refractory or relapsed patients. Targeted immunotherapy has emerged as a novel treatment option for these patients. Although unconjugated anti-cluster of differentiation (CD)30 antibodies showed minimal antitumor activity in early clinical trials, development of antibody-drug conjugates (ADCs) appears promising. Brentuximab vedotin is an ADC composed of an anti-CD30 antibody linked to a potent microtubule-disrupting agent monomethyl auristatin E (MMAE). It has the ability to target CD30-positive tumor cells and, once bound to CD30, brentuximab vedotin is internalized and MMAE is released to induce cell cycle arrest and apoptosis. In two Phase II trials, objective response was reported in 75% and 86% of patients with refractory or relapsed HL and systemic ALCL, respectively, with an acceptable toxicity profile. Based on these studies, the US Food and Drug Administration (FDA) granted accelerated approval of brentuximab vedotin in August 2011 for the treatment of refractory and relapsed HL and ALCL. We review the key characteristics of brentuximab vedotin, clinical data supporting its therapeutic efficacy, and current ongoing trials to explore its utility in other CD30-positive malignancies.

    • "The only unfavourable factor detected in our patient was the lung involvement. According to French Society of Pediatric Oncology the 3-year Overall Survival rate (OS) and Event Free Survival rate (EFS) were 83% and 66%, respectively, whereas in the BFM group the corresponding survival rates were 81% and 69% respectively [10, 11].

    ABSTRACT: A 13-year-old girl was admitted to our department with a history of severe pain of her left axilla and fever. On physical examination, a block of lymph nodes in her left axilla, diffuse papular rash, and red-violet swelling of her supraclavicular and subclavian region were noted. Imaging investigations revealed left axillar and supraclavicular lymphadenopathy and a small nodular shade in the upper lobe of her left lung. A biopsy from an axillary lymph node established the diagnosis of anaplastic large cell lymphoma (ALCL), whereas DNA of Mycobacterium tuberculosis was detected by polymerase chain reaction (PCR) in the same tissue biopsy. Patient was started on chemotherapy for ALCL and achieved remission of all initially involved fields. Nevertheless, two new nodular lesions were detected in the left lower lobe. Biopsy revealed granulomas, and PCR was positive for M. tuberculosis. Our patient received treatment with the combination of isoniazid and rifampin (12 months), pyrazinamide (the first 2 months), and maintenance chemotherapy for her ALCL for one year simultaneously. Four years later, she is disease free for both mycobacterial infection and lymphoma. We are reporting this successful management of mycobacterial infection in a patient with ALCL despite intensive chemotherapy that the patient received at the same time.
