Multiple myeloma treatment patterns and clinical outcomes in the Latin America Haemato-Oncology (HOLA) Observational Study, 2008-2016.

ABSTRACT: Limited data are available regarding contemporary multiple myeloma (MM) treatment practices in Latin America. In this retrospective cohort study, medical records were reviewed for a multinational cohort of 1103 Latin American MM patients (median age, 61 years) diagnosed in 2008-2015 who initiated first-line therapy (LOT1). Of these patients, 33·9% underwent autologous stem cell transplantation (ASCT). During follow-up, 501 (45·4%) and 129 (11·7%) patients initiated second- (LOT2) and third-line therapy (LOT3), respectively. In the LOT1 setting, from 2008 to 2015, there was a decrease in the use of thalidomide-based therapy, from 66·7% to 42·6%, and chemotherapy from, 20·2% to 5·9%, whereas use of bortezomib-based therapy or bortezomib + thalidomide increased from 10·7% to 45·5%. Bortezomib-based therapy and bortezomib + thalidomide were more commonly used in ASCT patients and in private clinics. In non-ASCT and ASCT patients, median progression-free survival (PFS) was 15·0 and 31·1 months following LOT1 and 10·9 and 9·5 months following LOT2, respectively. PFS was generally longer in patients treated with bortezomib-based or thalidomide-based therapy versus chemotherapy. These data shed light on recent trends in the management of MM in Latin America. Slower uptake of newer therapies in public clinics and poor PFS among patients with relapsed MM point to areas of unmet therapeutic need in Latin America.

Project description:PurposeDespite the call to increase the number of radiation oncologists in Latin America, the quality, similarity, and number of residency training programs are unknown. We seek to describe the current state of residency programs in radiation oncology in Latin America.Methods and materialsLatin American Residents in Radiation Oncology performed a cross-sectional analysis of universities and training centers for radiation oncologists in Latin America. Latin American Residents in Radiation Oncology members identified and contacted current residents and specialists at each center to obtain information and documents that described their training curricula.ResultsAs of 2020, 13 of 23 (56.5%) Latin American countries have radiation oncology training. Seventy-three training centers were identified (59 active and 14 inactive), associated with 28 universities. On average, each active center trains 2.6 new residents per year, and in total, 156 residents are trained annually. The average length of training programs is 3.6 years. Brazil and Mexico comprise 31 (52.5%) and 7 (11.9%) of active programs, respectively, and 64 (41.8%) and 50 (32.7%) residents, respectively. Training is available in 38 cities in 13 countries, and outside Brazil and Mexico, only 13 cities in 11 countries (9 capitals and 4 noncapital cities). Individualized curriculum documents were provided by 20 (83.3%) of 24 non-Brazilian programs, while 1 standardized guideline was provided for Brazilian training programs. These demonstrated variation between subjects taught, their devoted time, outside specialty rotations, and experiences in modern techniques. Seventy-five percent include volumetric modulated arc therapy, 70% stereotactic radiosurgery, and 55% stereotactic body radiation therapy training. One-hundred percent include gynecologic brachytherapy education and <50% brachytherapy education in other disease sites.ConclusionsTraining is highly centralized in capital cities. The number of trainees is insufficient to close the current human resource divide but is limited by available job openings. Over 50% of training programs now include technological training in stereotactic radiosurgery, stereotactic body radiation therapy, or volumetric modulated arc therapy; however, substantial variation still exists. The development of radiation oncology specialists must be improved and modernized to address the escalating demand for cancer care.

Project description:PurposeReal-world evidence on non-Hodgkin lymphoma (NHL) management in Latin America is currently lacking. The objective of this study was to describe treatment characteristics and outcomes of NHL in Latin America.MethodsA total of 2,967 patients with NHL with aggressive and indolent subtypes, including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), mantle-cell lymphoma (MCL), and mucosa-associated lymphoid tissue (MALT) lymphoma, with incident or prevalent diagnosis between 2006 and 2015, were retrospectively identified using clinical charts registered in the Hemato-Oncology Latin America Observational Registry. Associations between treatment regimen and age at diagnosis with clinical outcomes within each subtype were estimated using Cox proportional hazard regression.ResultsMost patients with NHL received 1L chemoimmunotherapy, most commonly cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with/without rituximab. Five-year survival rates were higher for MALT lymphoma (90.8%) and FL (87.6%) versus DLBCL (69.0%) and MCL (57.1%), with variations between countries. The median overall survival from first relapse for patients with DLBCL was 6.6 years, with lower risk of death for those diagnosed at age < 65 years (hazard ratio = 0.732; P = .0161). Patients achieved a longer median progression-free survival with 1L rituximab-CHOP (R-CHOP) versus CHOP or rituximab, cyclophosphamide, vincristine, and prednisone (RCVP) (7.7 v 3.0 or 1.8 years, respectively). Use of regimens other than R-CHOP was associated with a higher risk of death/progression for patients with DLBCL (rituximab, ifosfamide, carboplatin, and etoposide/ifosfamide, carboplatin, and etoposide) and FL (CHOP). There was no relationship between treatment prescribed and age at diagnosis with outcomes from first/second relapse in DLBCL and FL.ConclusionDifferences in treatment outcomes between NHL subtypes were observed, reflecting variations in NHL management and barriers to treatment access in Latin America. These data provide necessary evidence to understand NHL management in this region and highlight the need to improve treatment outcomes for these patients.
