Purpose Survivin, a member of the inhibitor of apoptosis (IAP) family, is not detected in normal adult tissues but is overexpressed in various cancers, including some types of lymphoma. The frequency and prognostic significance of survivin expression in anaplastic large-cell lymphoma (ALCL) is unknown. Materials and Methods We assessed for survivin expression in 62 ALCL tumors (30 anaplastic lymphoma kinase [ALK]-positive and 32 ALK-negative) obtained before doxorubicin-based chemotherapy. Given that survivin is a target of the STAT3 signaling pathway and STAT3 is activated in ALCL, survivin expression was also correlated with STAT3 activation. Results Survivin was expressed in 34 tumors (55%) and did not correlate with ALK. A significant association between survivin expression and STAT3 activation was observed (P = .007, Fisher's exact test). For the ALK-positive group, the 5-year failure-free survival (FFS) was 34% for patients with survivin-positive ALCL compared with 100% for patients with survivin-negative ALCL (P = .009, log-rank test). For the ALK-negative group, the 5-year FFS was 46% for patients with survivin-positive tumors compared with 89% for patients with survivin-negative tumors (P = .03, log-rank test). Overall survival was similarly worse for patients with survivin-positive tumors in both the ALK-positive and ALK-negative groups. Furthermore, multivariate analysis confirmed the independent prognostic value of survivin expression, along with age older than 60 years and Ann Arbor stage III or IV. Conclusion Survivin is expressed in approximately half of ALCL tumors and independently predicts unfavorable clinical outcome. Modulation of survivin expression or function may provide a novel target for experimental therapy in patients with ALCL.

Over the past 15 years, several biological and pathological characteristics proved their significance in pediatric anaplastic lymphoma kinase (ALK)-positive anaplastic large-cell lymphoma (ALCL) prognostic stratification. However, the identification of new non-invasive disease biomarkers, relying on the most important disease mechanisms, is still necessary. In recent years, plasmatic circulating small extracellular vesicles (S-EVs) gathered great importance both as stable biomarker carriers and active players in tumorigenesis. In the present work, we performed a comprehensive study on the proteomic composition of plasmatic S-EVs of pediatric ALCL patients compared to healthy donors (HDs). By using a mass spectrometry-based proteomics approach, we identified 50 proteins significantly overrepresented in S-EVs of ALCL patients. Gene Ontology enrichment analysis disclosed cellular components and molecular functions connected with S-EV origin and vesicular trafficking, whereas cell adhesion, glycosaminoglycan metabolic process, extracellular matrix organization, collagen fibril organization and acute phase response were the most enriched biological processes. Of importance, consistently with the presence of nucleophosmin (NPM)-ALK fusion protein in ALCL cells, a topological enrichment analysis based on Reactome- and Kyoto Encyclopedia of Genes and Genomes (KEGG)-derived networks highlighted a dramatic increase in proteins of the phosphatidylinositol 3-kinase (PI3K)/AKT pathway in ALCL S-EVs, which included heat shock protein 90-kDa isoform alpha 1 (HSP90AA1), osteopontin (SPP1/OPN) and tenascin C (TNC). These results were validated by Western blotting analysis on a panel of ALCL and HD cases. Further research is warranted to better define the role of these S-EV proteins as diagnostic and, possibly, prognostic parameters at diagnosis and for ALCL disease monitoring.

We present the clinicopathologic findings in 4 children with primary cutaneous anaplastic large cell lymphoma (C-ALCL). The patients ranged in age from 13 months to 8 years, with 3 females and 1 male. All presented with a rapidly enlarging mass involving the skin and subcutaneous tissue. Histologic evaluation showed sheets of large pleomorphic lymphoid cells that were diffusely and strongly CD30+. Tumor cells were CD45+ in 1 of 4 cases. Cells were of T-cell phenotype, with variable positivity for CD3 (3 of 4 cases) and CD5 (2 of 4 cases). All 4 cases were positive for CD4 and clusterin. Staining for anaplastic lymphoma kinase was negative in all cases. No evidence of systemic involvement was noted at initial presentation or over a follow-up of 5 to 78 months, although 3 patients had cutaneous recurrences. Primary C-ALCL has only rarely been described in the pediatric population. The high-grade histologic appearance of this lymphoma belies its generally favorable clinical course and prognosis. Recognition of this entity and its differentiation from other T-cell lymphomas that secondarily involve the skin is important to avoid unnecessarily aggressive therapy in these children.

Abstract Anaplastic large cell lymphoma (ALCL) represents approximately 2% of all non-Hodgkin lymphomas according to the recent Non-Hodgkin Lymphoma Classification Project. As defined in the revised European-American classification of lymphoid neoplasms (REAL), ALCL is a neoplasm of T-cell or null-cell lineage; 20% to 60% of cases are associated with the t(2;5)(p23;q35) translocation. ALCL commonly involves nodal as well as a wide variety of extranodal sites, although primary or secondary involvement of bone is rare. We describe the case of a 71-year-old man with stage IE T-cell ALCL, monomorphic variant, arising in the left anterior fifth rib and involving adjacent soft tissue without other sites of disease. The monomorphic histologic features hindered the initial recognition of this neoplasm as ALCL. However, strong uniform CD30 antigen expression and subsequent demonstration of the t(2;5)(p23;q35) translocation and anaplastic lymphoma kinase (ALK) immunoreactivity led to the correct diagnosis. We identified only 5 reported cases of T-cell and null-cell ALCL arising in bone and only 2 of these cases involved a single bone site. All 5 previously reported cases were ALCL of the classic type. We report a case of ALCL that is unique to our knowledge. This case of monomorphic ALCL was localized to bone and tumor cells contained the t(2;5)(p23;q35) translocation.
