Background The treatment of choice of newly diagnosed multiple myeloma (NDMM) is an induction with proteasome inhibitors followed autologous stem cell transplantation (HSCT). Since 2013, the treatment of these patients in the public system is based on CTD (cyclophosphamide, thalidomide, and dexamethasone). Aim To evaluate the response rates achieved with CTD, and the results of HSCT in patients with NDMM in the public setting. Material and Methods Data from patients considered as candidates for HSCT from different centers of the National Adult Antineoplastic Drug Program (PANDA, for its acronym in Spanish), diagnosed between 2013 and 2017, was analyzed. The response to treatment of first and second lines of treatment was evaluated, in addition to the results of HSCT. An optimal Response was defined as the sum of strict complete remission, complete remission and very good partial response (sCR, CR and VGPR). Results One hundred and seventy-seven patients were analyzed, 54% women, and 53% with IgG multiple myeloma. Information about the international staging system was retrieved in 127 patients (71%). Seventeen percent were ISS I, 22% in ISS II and 32% ISS III. CTD was used as first treatment in 106 patients (60%), and cyclophosphamide, bortezomib and dexamethasone (CyBorD) in 13 (7%). As first line, CTD had an overall response of 50.9%, and CyBorD of 76.9%. Thirty patients were treated with bortezomib as second line treatment. Forty patients (22%) underwent HSCT. The 5-year Overall Survival (OS) in transplanted patients and non-transplanted patients was 100 and 62% respectively (p < 0.01). Conclusions The response rate achieved by CTD in these patients is suboptimal. The response to CyBorD was better.

Autoimmune hemolytic anemia (AIHA) is an uncommon disease. In its presentation, it can be severe and even lethal. There is only one clinical report concerning this pathology in Chile.To describe the clinical characteristics and evolution of adult AIHA inpatients.Retrospective review of clinical records of adult AIHA inpatients between January 2010 and June 2018 was done. Demographic, clinical, laboratory and therapeutic information was analyzed. A descriptive, analytical and survival analysis was performed.Forty-three adult patients diagnosed with AHIA were hospitalized in a period of 8 years. Median age was 63 years (range 22-86 years), mostly women (72%). Warm antibodies were detected in 36 cases (84%) and cold antibodies in seven. Seventy two percent of the patients had an underlying cause, and 58% were secondary to lymphoproliferative neoplasms. All patients except two, received steroids as initial treatment, with response in 37 (90%) of them. Three refractory patients received rituximab, with response in all of them, and relapse in one. Median follow-up was 38 months (range 2-98 months). Five year overall survival was 72%.AHIA in adults inpatients is a heterogeneous disease, mainly due to warm antibodies, and to secondary etiology.
