AbstractPeripheral T-cell lymphomas (PTCL), with the exception of anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL), have a very poor prognosis. Although current first line chemotherapy continues to be a CHOP-like (cyclophosphamide, doxorubicin, vincristine, prednisone) regimen there is now data suggesting that the addition of etoposide in younger patients improves outcomes. Even for those patients who do have a response to therapy, the risk of relapse remains quite high. Although autologous transplant in first remission is often used, its role as consolidation therapy in first remission remains unclear and may preferentially benefit low-risk patients. In the relapsed setting, major advances have occurred with Food and Drug Administration (FDA) approval of 4 new agents (pralatrexate, romidepsin, belinostat, brentuximab vedotin) for relapsed/refractory PTCL since 2009. These 4 drugs represent the first agents ever approved specifically for this indication. Unfortunately, with the exception of ALCL for which brentuximab vedotin will likely substantially change our approach to treatment, there are still many patients for whom available drugs will not be effective, and it is for these patients that further advances are urgently needed.

BackgroundSeveral morphologic patterns of ALK+ anaplastic large cell lymphoma (ALCL) are recognized: common, small cell, lymphohistiocytic, Hodgkin-like, and composite patterns.1 Small cell (SC) and lymphohistiocytic (LH) patterns are thought to be closely associated with poorer outcome in children with ALK+ ALCL.2 However, the clinicopathologic and prognostic features of SC/LH patterns of ALK+ ALCL are not yet reported in adults. Recently, we found PD-L1 expression in a large subset of ALK+ ALCL cases, however, PD-L1 expression in SC/LH versus non-SC/LH ALCL has not been reported.MethodsAmong 102 adult patients with ALK+ ALCL seen at our institution from January 1, 2007 through August 30, 2018, 18 (18%) cases had a SC and/or LH pattern. The clinical, pathologic, and outcome data were compared between SC/LH and non-SC/LH ALK+ ALCL cases using Fisher’s exact test. Overall survival (OS) was analyzed using the Kaplan-Meier method and compared using the log-rank test.ResultsThere were no significant differences in clinical features including age, gender, nodal versus extranodal involvement, B symptoms, stage, leukocytosis/lymphocytosis, and serum LDH levels between patients with SC/LH versus non-SC/LH ALK+ ALCL. Compared to non-SC/LH cases, SC/LH ALCL was more often positive for CD2 (92% vs. 36%, p = 0.0007), CD3 (81% vs. 15%, p = 0.0001), CD7 (80% vs. 37%, p = 0.03), and CD8 (54% vs. 7%, p = 0.0006). SC/LH ALCL showed a trend of decreased PD-L1 expression than non-SC/LH cases (24% vs. 46%, p = 0.11). There were no significant differences in the expression of CD4, CD5, CD25, CD43, CD45, CD56, TCR A/B, TCR G/D, cytotoxic markers, EMA, Ki-67 proliferation index. The induction chemotherapy and response rate in patients with SC/LH ALK+ ALCL were similar to patients with non-SC/LH ALK+ ALCL. After a median follow-up of 30.5 months (range, 0.3–224 months), there was no significant difference in OS between patients with SC/LH versus non-SC/LH ALK+ ALCL (p = 0.88).ConclusionsIn adults with ALK+ALCL, the SC/LH morphologic pattern is associated with a CD8+ T cell immunophenotype and retention of expression of T cell markers (CD2, CD3, and CD7). The trend of decreased PD-L1 expression in SC/LH ALCL suggests that these patients may not be ideal candidates for PD-L1 immunotherapy. The SC/LH patterns of ALK+ ALCL have no impact on the prognosis of adult patients which is in contrast to the reported association of the SC/LH patterns with poorer outcome in children with ALK+ ALCL.Ethics ApprovalThe study was approved by the Institutional Review Board at MD Anderson Cancer Center, Approval number: PA16-0897ReferencesSwerdlow SH, Campo E, The 2016 revision of the World Health Organization classification of lymphoid neoplasms.

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.
