PURPOSE Adult T-cell leukemia/lymphoma (ATLL) is an aggressive disease caused by the human T-cell leukemia virus type 1. Real-world data of ATLL in Latin America are lacking. PATIENTS AND METHODS We analyzed patients with ATLL (acute, lymphomatous, chronic, and smoldering) encountered in 11 Latin American countries between 1995 and 2019. Treatment response was assessed according to the 2009 consensus report. Survival curves were estimated using the Kaplan-Meier method and log-rank test. RESULTS We identified 253 patients; 226 (lymphomatous: n = 122, acute: n = 73, chronic: n = 26, and smoldering: n = 5) had sufficient data for analysis (median age 57 years). Most patients with ATLL were from Peru (63%), Chile (17%), Argentina (8%), and Colombia (7%). Hypercalcemia was positively associated with acute type (57% v lymphomatous 27%, P = .014). The median survival times (months) were 4.3, 7.9, 21.1, and not reached for acute, lymphomatous, chronic, and smoldering forms, with 4-year survival rates of 8%, 22%, 40%, and 80%, respectively. First-line zidovudine (AZT)-interferon alfa (IFN) resulted in an overall response rate of 63% (complete response [CR] 24%) for acute. First-line chemotherapy yielded an overall response rate of 41% (CR 29%) for lymphomatous. CR rate was 42% for etoposide, cyclophosphamide, vincristine, doxorubicin, and prednisone versus 12% for cyclophosphamide, vincristine, doxorubicin, and prednisone–like regimen ( P < .001). Progression-free survival at 1 year for acute type patients treated with AZT-IFN was 67%, whereas 2-year progression-free survival in lymphomatous type patients who achieved CR after chemotherapy was 77%. CONCLUSION This study confirms Latin American ATLL presents at a younger age and has a high incidence of lymphomatous type, low incidence of indolent subtypes, and worse survival rates as compared with Japanese patients. In aggressive ATLL, chemotherapy remains the preferred choice for lymphomatous favoring etoposide-based regimen (etoposide, cyclophosphamide, vincristine, doxorubicin, and prednisone), whereas AZT-IFN remains a good first-line option for acute subtype.

Introduction: POEMS syndrome is a rare paraneoplastic syndrome caused by an underlying plasma cell disorder. The acronym refers to the following features: polyradiculoneuropathy, organomegaly, endocrinopathy, monoclonal paraproteinemia, and skin changes. Methods: The study was conducted at 24 hematological centers across 8 Latin-American countries. The study included a total of 46 patients {median age was 52 years (interquartile range [IQR]: 42–61.5), 30 males and 16 females} fulfilling the POEMS syndrome criteria diagnosed over a period of 12 years (January 1, 2011, through July 31, 2023). Epidemiological and clinical data were collected in an ad hoc database sent to the members of GELAMM, as well as the Kolmogorov-Smirnov test and Kaplan-Meier estimates. Results: All patients had polyneuropathy and monoclonal gammopathy; 89% had bone marrow plasma cell infiltration, 33% had sclerotic bone lesions. Only 10 patients underwent vascular endothelial growth factor (VEGF) testing in plasma samples. The paraproteinemia was IgG λ in 32% and IgA λ in 30%. 59% patients presented with cutaneous changes, mainly hyperpigmentation, 54% had organomegaly, and 74% endocrinopathy. The median interval from symptom onset to diagnosis was 7.7 months (IQR: 4.0–12.6). 69% of patients received a single line of treatment. The median follow-up period was 25 months (IQR: 9.37–52.0) and the 2-year overall survival rate was 100%. All patients who underwent transplantation (43%) are alive, with a median follow-up of 45.62 months (IQR: 15.46–70). Conclusion: This study investigates POEMS syndrome in Latin America and presents an initial overview of the disease in the region. VEGF usage is recommended for accurate diagnosis, but only 7 hematology centers in the region used it. Survival rate in Latin America is comparable with those observed internationally.
