RESUMO

Clinical trials comparing bendamustine/rituximab (BR) with cyclophosphamide-based regimens (RCHOP/RCVP) have pooled various histologies of indolent B-cell lymphomas. We examined real-life outcomes of older patients with follicular (FL), mantle cell (MCL), or marginal zone/lymphoplasmacytic lymphoma (MZL/LPL), treated with these first-line regimens. We identified Medicare beneficiaries with FL, MCL, or MZL/LPL, who received either first-line BR or RCHOP/RCVP in 2009-2016, and matched groups using a propensity score. Outcomes of claims-based event-free survival (EFS), overall survival (OS), toxicity, secondary cancers, and costs were compared in the aggregate cohort (N = 2736), and in separately matched histology-specific subcohorts. In the aggregate cohort, EFS was better with BR than with RCHOP/RCVP (hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.70-0.87). Acute toxicity was lower with BR, including rates of hospitalizations (33% vs 45%), infections (21% vs 30%), cardiovascular events, and transfusions, yet OS did not differ (HR, 1.03; 95% CI, 0.91-1.17) and Medicare spending was higher. There was no difference in the cumulative incidence of secondary cancers (subhazard ratio, 1.11; 95% CI, 0.83-1.48). The EFS advantage of BR was pronounced in MCL (N = 690; HR, 0.64; 95% CI, 0.54-0.76), but less so in FL (N = 1330; HR, 0.83; 95% CI, 0.69-0.98) and absent in MZL/LPL (N = 574; HR, 0.92; 95% CI, 0.73-1.17). Despite improved EFS and lower toxicity, the shift from RCHOP/RCVP to BR in clinical practice did not improve OS for older patients with indolent B-cell lymphomas. Frequent infections and hospitalizations underscore the need for safer treatment approaches in this population. Secondary cancers do not appear to be increased after BR compared with RCHOP/RCVP.

RESUMO

BACKGROUND: Induction chemotherapy for acute myeloid leukemia (AML) is based on the "7+3" cytarabine/anthracycline regimen. A nonhypocellular day 14 (D14) bone marrow sample with a blast count > 5% to 10% is suggestive of residual leukemia, for which a second course of induction chemotherapy has been recommended. Although the prognostic value of D14 bone marrow findings has been established, its use as a decision point is controversial because the benefit of repeat induction has been questioned. PATIENTS AND METHODS: In the present single-center retrospective study of 113 patients with newly diagnosed AML, we evaluated the role of cellularity on the clinical outcomes of patients with residual morphologic leukemia (blasts ≥ 5%). Among 64 patients with D14 bone marrow samples, 31 had residual morphologic leukemia. RESULTS: The complete remission (CR) rates were greater for the hypocellular (11 of 16) than for the nonhypocellular (4 of 15) patients (P = .03). The median overall survival (OS) for the hypocellular D14 patients was longer than that for the nonhypocellular patients (17 vs. 8 months; P = .02). No significant difference between the receipt of reinduction therapy and CR or OS was found on logistic or survival model analysis. The specificity for residual leukemia on D14 bone marrow samples was better for cellularity ≥ 20% and blasts ≥ 20% than for blasts ≥ 5%. CONCLUSION: The results of our study have shown that patients with < 20% cellularity and < 20% blasts on the D14 bone marrow assessment should continue observation until recovery rather than receive additional immediate therapy.

RESUMO

Until recently, warfarin has been the primary treatment of venous thromboembolism (VTE). Limited data are available regarding physician attitudes toward anticoagulant choice in the setting of novel oral anticoagulant (NOAC) availability. This study sought to evaluate attending physician attitudes toward NOACs. A survey was sent to attending physicians from internal medicine (primary care and hospitalist medicine), family medicine, cardiology, and hematology-oncology asking about their preference and reasoning for choice of oral anticoagulant for the treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE). Warfarin was the most common choice of initial treatment of both DVT (85.6%) and PE (89%). Among the specialties surveyed, cardiologists were more likely to use rivaroxaban as initial treatment of VTE as compared to other specialties including internal medicine or hematology (p=0.011 for DVT and 0.004 for PE). Cost-effectiveness and lack of a reversal agent were cited as the major disadvantages for NOAC use.

RESUMO

BACKGROUND: Medical oncologists often must deliver bad news. The authors were interested in the extent of formal training in delivering bad news in hematology/oncology fellowships in the United States. METHODS: An e-mail survey was sent to all hematology/oncology fellowship program directors in the United States. Surveys were e-mailed to 124 program directors and responses were received either via e-mail or regular mail. Program directors were asked the adequacy, the perceived necessity, the quality of this training, and the institutional support provided. It was also intended to elicit responses about the degree of formal training fellows receive in delivering bad news. chi(2) Statistics were used to perform comparisons between items; p values of less than 0.05 were considered statistically significant. RESULTS: Sixty-five surveys were completed and returned (52% response rate). The majority of programs, 82%, are in urban areas and 97% of the primary teaching hospitals are considered tertiary care centers and 46% of programs carry a National Cancer Institute (NCI) designation. Median number of fellows in a training program is 6 with the range being 3 to 46. Eighty-nine percent of program directors reported that they themselves received little to no formal training in delivering bad news, but they report 37% of current fellows receive little to no formal training with 40% receiving some training and additional 23% receiving moderate to extensive training (p < 0.001). Sixty-three percent of program directors felt that extensive, formal training is important for skill development in delivering bad news, while an additional 34% felt that some training is useful. Only 3% of respondents did not believe any training is needed. Seventy-six percent of program directors want improvements in how their fellows are trained, but 43% reported little to no institutional support for training (p < 0.001). CONCLUSIONS: Of the program directors who responded to our survey, a large majority did not have formal training in delivering bad news. Despite this lack of training, most program directors felt that training was useful for skill development in delivering bad news. The majority of today's fellows do receive training in delivering bad news. However, there was still a significant percentage of program directors who reported little or no formal training for fellows. Most program directors would like to see improvements in how fellows are trained. Specific institutional support for training fellows in delivering bad news remains lacking.
