PURPOSE Patients with the activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) historically showed inferior survival with standard rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Phase II studies demonstrated that adding the immunomodulatory agent lenalidomide to R-CHOP improved outcomes in ABC-type DLBCL. The goal of the global, phase III ROBUST study was to compare lenalidomide plus R-CHOP (R2-CHOP) with placebo/R-CHOP in previously untreated, ABC-type DLBCL. METHODS Histology and cell-of-origin type were prospectively analyzed by central pathology prior to random assignment and study treatment. Patients with ABC-DLBCL received lenalidomide oral 15 mg/d, days 1-14/21 plus standard R-CHOP21 versus placebo/R-CHOP21 for six cycles. The primary end point was progression-free survival (PFS) per independent central radiology review. RESULTS A total of 570 patients with ABC-DLBCL (n = 285 per arm) were stratified by International Prognostic Index score, age, and bulky disease, and randomly assigned to R2-CHOP or placebo/R-CHOP. Baseline demographics were similar between arms. Most patients completed six cycles of treatment: 74% R2-CHOP and 84% placebo/R-CHOP. The most common grade 3/4 adverse events for R2-CHOP versus placebo/R-CHOP were neutropenia (60% v 48%), anemia (22% v 14%), thrombocytopenia (17% v 11%), and leukopenia (14% v 15%). The primary end point of PFS was not met, with a hazard ratio of 0.85 (95% CI, 0.63 to 1.14) and P = .29; median PFS has not been reached for either arm. PFS trends favoring R2-CHOP over placebo/R-CHOP were seen in patients with higher-risk disease. CONCLUSION ROBUST is the first DLBCL phase III study to integrate biomarker-driven identification of eligible ABC patients. Although the ROBUST trial did not meet the primary end point of PFS in all patients, the safety profile of R2-CHOP was consistent with individual treatments with no new safety signals.

Background The purpose of this study was to examine gender differences in authorship of manuscripts in select high‐impact cardiology journals during the early coronavirus disease 2019 (COVID‐19) pandemic. Methods and Results All manuscripts published between March 1, 2019 to June 1, 2019 and March 1, 2020 to June 1, 2020 in 4 high‐impact cardiology journals ( Journal of the American College of Cardiology , Circulation , JAMA Cardiology , and European Heart Journal ) were identified using bibliometric data. Authors' genders were determined by matching first name with predicted gender using a validated multinational database (Genderize.io) and manual adjudication. Proportions of women and men first, co‐first, senior, and co‐senior authors, manuscript types, and whether the manuscript was COVID‐19 related were recorded. In 2019, women were first authors of 176 (22.3%) manuscripts and senior authors of 99 (15.0%) manuscripts. In 2020, women first authored 230 (27.4%) manuscripts and senior authored 138 (19.3%) manuscripts. Proportions of woman first and senior authors were significantly higher in 2020 compared with 2019. Women were more likely to be first authors if the manuscript's senior author was a woman (33.8% for woman first/woman senior versus 23.4% for woman first/man senior; P <0.001). Women were less likely to be first authors of COVID‐19‐related original research manuscripts ( P =0.04). Conclusions Representation of women as key authors of manuscripts published in major cardiovascular journals increased during the early COVID‐19 pandemic compared with similar months in 2019. However, women were significantly less likely to be first authors of COVID‐19‐related original research manuscripts. Future investigation into the gender‐disparate impacts of COVID‐19 on academic careers is critical.

Abstract Purpose The high-value pharmacy enterprise (HVPE) framework and constituent best practice consensus statements are presented, and the methods used to develop the framework’s 8 domains are described. Summary A panel of pharmacy leaders used an evidence- and expert opinion–based approach to define core and aspirational elements of practice that should be established within contemporary health-system pharmacy enterprises by calendar year 2025. Eight domains of an HVPE were identified: Patient Care Services; Business Services; Ambulatory and Specialty Pharmacy Services; Inpatient Operations; Safety and Quality; Pharmacy Workforce; Information Technology, Data, and Information Management; and Leadership. Phase 1 of the project consisted of the development of draft practice statements, performance elements, and supporting evidence for each domain by panelists, followed by a phase 2 in-person meeting for review and development of consensus for statements and performance elements in each domain. During phase 3, the project cochairs and panelists finalized the domain drafts and incorporated them into a full technical report and this summary report. Conclusion The HVPE framework is a strategic roadmap to advance pharmacy practice by ensuring safe, effective, and patient-centered medication management and business practices throughout the health-system pharmacy enterprise. Grounded in evidence and expert recommendations, the statements and associated performance elements can be used to identify strategic priorities to improve patient outcomes and add value within health systems.

Background: Multiple myeloma (MM) is typically diagnosed in patients (pts) aged 65-74 y (SEER: Myeloma. 2019); therefore, many pts present with concomitant metabolic disorders such as diabetes (18%-22% prevalence of type 2 diabetes [T2D; BMC Cancer. 2020;20:489]). Obesity (body mass index [BMI], ≥ 30 kg/m2) is associated with increased prevalence of T2D (Int J Clin Pract. 2007;61:737), and both are suggested risk factors for MM (Blood. 2012;119:4845; Bone Marrow Transpl. 2014;49:1009). Results from single-center, retrospective studies have shown poorer clinical features and survival outcomes in diabetic pts with MM vs their nondiabetic counterparts (Eur J Haematol. 2012;89:320, Br J Cancer. 2014;111:628). The Connect® MM Registry (NCT01081028) is a large, US, multicenter, prospective observational cohort study of largely community-based pts with NDMM. Reported here is a descriptive analysis assessing differences in baseline (BL) characteristics, treatment patterns, and survival outcomes in diabetic vs nondiabetic pts enrolled in the Connect MM Registry. Methods: Pts with NDMM (N = 3011) were enrolled at 250 community, academic, and government sites. Eligible pts were aged ≥ 18 y with symptomatic MM diagnosed ≤ 2 months (mo) pre-enrollment per International Myeloma Working Group criteria (Leukemia. 2009;23:3). Diabetic pts were defined as those with a history of diabetes and also receiving antidiabetic treatment at BL; those without a history of diabetes and not receiving antidiabetic treatment at BL were defined as nondiabetic pts. Descriptive statistics were used for BL characteristics and treatment regimens. Survival outcomes (progression-free survival [PFS] and overall survival [OS]) were analyzed using Cox regression and adjusted for covariates. Results: Of the 2845 pts included in this analysis, 467 (16%) were diabetic, and 2378 (84%) were nondiabetic. The median age was 69 y for diabetic pts and 66 y for nondiabetic pts, with fewer Black pts (12.2% vs 19.5%) in the nondiabetic group. The proportion of men was higher in the diabetic vs the nondiabetic group (61.9% vs 56.6%). Similar percentages of pts had ECOG PS of 0-1 in both groups (53.3% vs 55.3%). Obesity was more prevalent in diabetic vs nondiabetic pts (55.9% vs 30.4%). More diabetic pts had a history of hypertension requiring treatment vs nondiabetic pts (84.2% vs 52.5%). The prevalence of chromosomal abnormalities was comparable between the groups (within the limitation that data were missing in a substantial number of pts). Among MM-defining criteria, diabetic pts had a higher incidence of hypercalcemia (11.8% vs 8.5%), anemia (50.3% vs 46.5%), and increased creatinine (23.8% vs 19%), whereas measured kidney function was similar. A lower proportion of diabetic than nondiabetic pts received stem cell transplantation (SCT; 28.9% vs 41.5%) and triplet regimens during first induction (48.2% vs 52.8%%). The use of ≥ 2 novel agents during first line (1L) was lower in diabetic than nondiabetic pts (27.8% vs 34.6%), but use of a single novel agent (63.4% vs 60%) and alkylator in 1L (20.6% vs 22.4%) was comparable. The top five 1L regimens were similar for both groups, with lenalidomide + bortezomib + dexamethasone being the most common 1L regimen, and lenalidomide the most common maintenance therapy. Diabetic pts had significantly shorter adjusted median PFS (24.4 vs 31.5 mo; hazard ratio [HR], 1.24; P = 0.001; Fig. 1A) and median OS (60 vs 72.6 mo; HR, 1.29; P = 0.001; Fig. 1B) than nondiabetic pts. In a subgroup analysis by BMI, diabetic pts had significantly shorter OS than nondiabetic pts (for BMI &lt; 30 [50.8 vs 73.1 mo; HR, 1.51; P = 0.0001] and BMI ≥ 30 [56.4 vs 78.6 mo; HR, 1.51; P &lt; 0.0001]). Conclusions: Diabetic pts with NDMM had poorer BL features and were less likely to receive SCT and triplet regimens and/or aggressive upfront treatment. Regardless of BMI, diabetic pts had shorter median OS than nondiabetic pts, suggesting that diabetes might be a stronger factor for survival than obesity. These results support a previous analysis of the Connect MM Registry that identified history of diabetes as a predictive prognostic factor for poor OS (Br J Haematol. 2019;187:602). Limitations of this analysis include limited detail on the care/management of diabetes and steroid use/dosage (which can be challenging for glycemic control). These findings highlight the need to provide better supportive care for diabetes management in MM pts to improve survival. Disclosures La: Celgene BMS: Consultancy.

Introduction: MF is a clonal stem cell disorder characterized by progressive bone marrow failure, extramedullary hematopoiesis, and debilitating constitutional symptoms. Approximately 60% of pts develop anemia within a year of diagnosis; pts who are transfusion dependent have worse survival and quality-of-life outcomes (Tefferi A, et al. Mayo Clin Proc 2012;87:25-33). Treatment for MF-associated anemia remains critically unaddressed, with no approved therapies available. Luspatercept is a first-in-class erythroid maturation agent that has been shown to increase hemoglobin and reduce transfusion burden in pts with myelodysplastic syndromes (Fenaux P, et al. N Engl J Med 2020;382:140-51) and β-thalassemia (Cappellini MD, et al. N Engl J Med 2020;382:1219-31). Pts have also achieved multiple response episodes with luspatercept (Fenaux P, et al. Blood 2019;134:841). We previously reported findings from the ongoing open-label, phase 2 ACE-536-MF-001 trial evaluating luspatercept in pts with MF-associated anemia (Gerds AT, et al. Blood 2019;134:557). Here we report updated study results, focusing on response in pts requiring RBC transfusions. Methods: 79 pts with MF and anemia were enrolled (Figure). Of these, 43 were requiring RBC transfusions, defined as 6-12 U/84 d prior to treatment, or 4-12 U/84 d for the 3 expansion cohort pts. Pts in Cohort 3B received a stable ruxolitinib (RUX) dose for ≥ 16 wks (40 wks for expansion cohort pts), whereas Cohort 2 pts did not (Figure). Pts in Cohort 3B received a median RUX dose of 20 mg/d (range 5-40) for a median of 73 wks (range 29-359) prior to treatment. Pts received luspatercept every 21 d at a starting dose of 1.0 mg/kg (1.33 mg/kg for 3 expansion cohort pts in Cohort 3B), with doses escalating up to 1.75 mg/kg; 81% and 50% of pts in Cohorts 2 and 3B escalated to 1.75 mg/kg. Primary endpoint for pts receiving transfusions was RBC transfusion-independence (RBC-TI) for ≥ 12 consecutive wks within the first 24 wks on study. However, as responses were observed that did not fall within the 24-wk response window, additional assessments were conducted for the entire treatment duration for RBC-TI and ≥ 50% decrease in RBC transfusions (minimum 4 RBC U decrease) from baseline. Intent-to-treat data were analyzed as of March 29, 2020. Results: Pts in Cohorts 2 and 3B received a median of 8 cycles of luspatercept (range 1-39), for a median (mean) duration of 24 (31) and 23 (39) wks, respectively. Pts in Cohorts 2 and 3B received a median of 2.7 RBC U/28 d (range 1-5) and 2.7 RBC U/28 d (range 2-4), respectively. For the primary endpoint, 2/21 (10%) and 6/22 (27%) pts receiving transfusions in Cohorts 2 and 3B achieved RBC-TI over any consecutive 12 wks during the first 24 wks. Median time to start of first RBC-TI response period in Cohorts 2 and 3B was 1.5 days and 37 days; median duration of response was 49 wks (range 16-82) and 42 wks (range 12-111), respectively. When assessing the entire treatment period, 4/21 (19%) and 8/22 (36%) pts in Cohorts 2 and 3B achieved RBC-TI ≥ 12 wks, respectively. 25% of the RBC-TI responders in both cohorts experienced 2 separate episodes of RBC-TI ≥ 12 wks. Median cumulative duration of all individual ≥ 12-wk response episodes of RBC-TI was 59 wks (range 24-82) in Cohort 2 and 55 wks (range 12-116) in Cohort 3B. 8/21 (38%) and 10/22 (46%) pts in Cohorts 2 and 3B achieved a ≥ 50% reduction in RBC transfusion burden (minimum ≥ 4 U reduction) over 12 wks; of these, 38% and 20% of responders in Cohorts 2 and 3B experienced 2 separate ≥ 12-wk response episodes, and 1 pt (13%) in Cohort 2 experienced 3 separate responses. 4/15 (27%) and 8/14 (57%) pts in Cohorts 2 and 3B who reached 24 wks of treatment achieved clinical benefit and therefore continued luspatercept on an ongoing basis. Safety is reported for all 79 pts on study. 5 (6%) pts had grade 3-4 treatment-related adverse events (AEs); these AEs were diarrhea (n = 2), dehydration (n = 1), and hypertension (n = 3). There were no treatment-related deaths. Treatment-related AEs (any grade) occurring in ≥ 5% of pts were hypertension (13%), bone pain (9%), and diarrhea (5%). 8 (10%) pts had ≥ 1 AE leading to discontinuation. 16 (20%) pts remain on treatment. Conclusions: These longer-term findings suggest durable activity of luspatercept in pts with MF-associated anemia. In addition, a quarter of pts receiving transfusions achieved more than one ≥ 12-wk episode of RBC-TI response with luspatercept. The incidence of grade 3-4 AEs with luspatercept was low.

Introduction: IBER is an oral, potent novel cereblon E3 ligase modulator (CELMoD) agent with marked synergistic tumoricidal and immune-stimulatory effects in combination with BORT or DARA in preclinical models. CC-220-MM-001 is a phase 1/2 study evaluating dose escalations of IBER with different treatment combinations in independent cohorts, in patients (pts) with RRMM (NCT02773030); the IBER + DEX cohort showed a favorable safety profile with promising efficacy and a selected IBER RP2D of 1.6 mg 21/28 days (D). Here, we present results from the IBER + DARA + DEX (IberDd) and IBER + BORT + DEX (IberVd) cohorts. Methods: Eligible pts had received ≥ 2 prior regimens in the IberDd cohort, and ≥ 1 prior regimen in the IberVd cohort, containing at least lenalidomide or pomalidomide, and a proteasome inhibitor (PI), and had experienced disease progression on or within 60 days of last MM therapy. Escalating doses of IBER were given orally, in the IberDd cohort on D1-21, with DARA (16 mg/kg) on D1, D8, D15, and D22 (cycles [C]1-2), D1 and D15 (C3-6), and D1 (C ≥ 7), of each 28-day cycle; in the IberVd cohort, on D1-14, with BORT (1.3 mg/m2) on D1, D4, D8, and D11 (C1-8), and on D1 and D8 (C ≥ 9), of each 21-day cycle. In both cohorts DEX was given weekly. Primary objectives were to evaluate MTD, RP2D, and safety separately for each cohort; a key secondary objective was preliminary assessment of efficacy. Immune profiling was evaluated by flow cytometry from pt peripheral blood at C1D1, C2D15, C4D1, and C4D15. Results: As of June 18, 2020, 19 pts had received IberDd and 21 pts IberVd. Baseline characteristics for the 2 independent cohorts are shown in the table. All pts were refractory to their last prior regimen, and exposure to prior regimens was heterogeneous. IBER doses ranged from 1.0 to 1.6 mg; the MTD/RP2D has not been reached in either cohort. Median follow-up was 5 (0-14) and 3 (0-11) months, 10 (53%) and 13 (62%) pts continue on treatment, median cycles received was 5 (1-14) and 4.5 (1-17), with IberDd and IberVd, respectively. Grade (Gr) 3-4 treatment-emergent adverse events (TEAEs) were reported in 14 (78%) pts with IberDd, and in 13 (65%) pts with IberVd. Most frequent Gr 3-4 TEAEs of interest included neutropenia (50%), leukopenia (22%), and anemia (22%) with IberDd; and neutropenia (20%) and thrombocytopenia (20%) with IberVd. In both cohorts, neutropenia was managed with G-CSF. One pt (IberDd; 1.2 mg dose) had Gr 4 neutropenic sepsis. Occurrence of Gr 3-4 non-hematological TEAEs was low in both cohorts. One pt had Gr 2 infusion-related reaction with IberDd, and 3 pts had Gr 1-2 peripheral neuropathy with IberVd. Six (33%) and 4 (20%) pts had IBER dose reductions with IberDd and IberVd, respectively. In the IberDd cohort, with 12/19 (63%) DARA-refractory pts and 11 (58%) quad-class-refractory pts, the overall response rate (ORR) was 35% across all dosing groups (2 very good partial responses [VGPRs], 4 partial responses [PRs]); the clinical benefit rate (CBR) was 47% and disease control rate (DCR) was 88%. In the IberVd cohort, with 16/21 (76%) PI-refractory pts, 9 (43%) BORT-refractory pts, and 10 (48%) quad-class refractory pts, ORR was 50% (1 complete response, 3 VGPRs, 6 PRs); CBR was 65% and DCR was 85%. Responses with IberDd and IberVd were observed irrespective of DARA- and BORT-refractoriness, respectively. Median time to response was 4.1 (4.1-12.0) and 4.9 (3.0-13.1) weeks, in the IberDd and IberVd cohorts, respectively; median duration of response was not reached in both cohorts. Immune profiling showed dose-dependent decreases in B cells and increases in activated and differentiated T cells, in both cohorts. Except for reductions in CD38+ T cells in pts receiving IberDd, these observations were similar in pts treated with IBER + DEX. Conclusions: IberDd and IberVd showed a favorable tolerability profile in heavily pretreated RRMM pts, with promising clinical activity, even among pts refractory to the last prior regimen and previously exposed to IMiD agents, PIs, and CD38 antibodies. Immune-profiling data confirm that IBER + DEX was pharmacodynamically active in triplet combination and not augmented by the addition of DARA or BORT. The study is ongoing with continued enrollment at the 1.6 mg dose level for both cohorts. Updated results, including the MTD/RP2D, will be presented at the meeting. These results support the further development of IBER-based regimens in MM; phase 3 trials are planned to further evaluate these combinations.

Background Diffuse large B-cell lymphoma (DLBCL) is the most common aggressive non-Hodgkin lymphoma subtype with a 5-year survival of ~64%. While DLBCL is treated using immunochemotherapy (IC) with curative intent, 20%-40% of patients do not reach remission or relapse post IC. Clonal somatic mutations have been associated with aging, hematologic malignancies (predominately myeloid), and reduced OS in the general population. The objective of this study was to evaluate the association of clonal somatic mutations with event-free survival (EFS) and overall survival (OS). Methods We studied newly diagnosed DLBCL cases treated with IC who were enrolled in the Molecular Epidemiology Resource (MER) of the University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellence (SPORE). Clinical and treatment data were abstracted from medical records and all patients were systematically followed for disease outcomes. Pre-treatment DNA was extracted from matched peripheral blood and paraffin-embedded tumor tissue, and whole exome sequencing was conducted at 100x coverage. From the peripheral blood, allele counts from GVCF files produced by HaplotypeCaller in GATK were extracted for 42 genes commonly associated with clonal hematopoiesis (e.g. DNMT3A, TET2, and ASXL1). Mutations were deemed clonal somatic if the population minor allele frequency was &lt;0.5% in ExAC and had a variant allele fraction (VAF) that deviated from 0.5 using a binomial distribution test at p&lt;0.001. Furthermore, mutations had to have a minimum alternate read count of at least 5 reads, a VAF greater than or equal to 10%, and met at least one of the following criteria: CAVA impact of "HIGH"; pathogenic/likely pathogenic per ClinVar; or reported in COSMIC at least 10 times. EFS was defined as time from diagnosis to disease progression, relapse, retreatment, or death due to any cause. The association of clonal somatic mutations with prognosis was estimated using Kaplan-Meier curves, and hazard ratios (HR) and 95% confidence intervals (CI) from Cox regression. Associations were adjusted for age at diagnosis, sex, and the International Prognostic Index (IPI). Results The study consisted of 261 DLBCL patients treated with IC. The median age at diagnosis was 65 years (range 20-90) and 56% were male. With a median follow-up time of 5.1 years (range 0.1-15.0), there were 100 events and 80 deaths. A total of 17 (6.5%) patients had clonal somatic mutations, and16 patients were over the age of 60. A total of 8 (of 42) genes had clonal somatic mutations, with SF3B1, ASXL1, and TET2, being the most frequent (4 individuals per gene). VAFs ranged from 0.10 to 0.28 and none of the patients had multiple mutations. Additionally, the clonal somatic variants found in the peripheral blood were abscent in the tumor sample. Of the 17 patients with clonal somatic mutations, 12 had an event while 88 patients without a mutation had an event. In a univariate analysis, clonal somatic mutations were associated with inferior EFS (HR=2.55, 95% CI 1.39-4.68, p=0.002; Figure 1A). After adjusting for age, sex, and IPI, clonal somatic mutations remained associated with inferior EFS (HR=2.02, 95% CI 1.09-3.74, p=0.026). Clonal somatic mutations were also associated with inferior OS in the univariate analysis (HR=2.06, 95% CI 0.99-4.29, p=0.053), which attenuated after multivariate adjustment (HR=1.59, 95% CI: 0.76-3.34, p=0.22, Figure 1B). Although based on small numbers, mutations in SF3B1 were associated with inferior EFS (HR=3.25, 95% CI 1.16-9.12, p=0.025), but did not reach significance for OS (HR=2.56, 95% CI 0.78-8.38, p=0.120). Conclusions In this novel study of newly diagnosed DLBCL patients, clonal somatic mutations were identified in 6.5% of patients and were associated with inferior outcomes. Additional research is required at deeper sequencing to validate these findings and integration with tumor genomics is required to understand the prognosis of DLBCL patients with smaller clonal populations.

Background: To evaluate differences in the proportion of uterine fibroid (UF) treatments that are uterine-sparing between Black women and White women and identify factors that could explain disparities. Methods: Women at age 18–54 years who were enrolled from 10 clinical sites in the United States into the Comparing Options for Management: Patient-Centered Results for UFs (COMPARE-UF) treatment registry completed questionnaires before their UF procedure. UF symptoms and quality of life were assessed by questionnaires. Details on UF imaging and treatment (hysterectomy, myomectomy, or uterine artery embolization [UAE]) were collected from each patient's medical record. Random-effects logistic regression was used to assess the association between race and the odds of having a uterine-sparing procedure versus hysterectomy. Subgroup analyses compared each uterine-sparing procedure with hysterectomy. Results: In this cohort of 1141 White women and 1196 Black women, Black women tended to be younger (median 41.0 vs. 42.0 years) and report worse symptoms, pain, and function on every scale compared with White women. Black women were more likely to have had a prior UF treatment compared with White women (22.8% vs. 14.6%). White women had more hysterectomies (43.6% vs. 32.2%) and myomectomies (50.9% vs. 50.2%) versus Black women. Black women had more UAEs (15.1% vs. 4.7%) than White women. After adjusting for clinical site and other variables, Black women had greater odds than White women of having a myomectomy (odds ratio [OR] = 2.41, 95% confidence interval [CI] = 1.63–3.56) or a UAE versus hysterectomy (OR = 4.24, 95% CI = 2.41–7.46). Conclusion: In these participants, Black women were more likely to schedule a uterine-sparing UF treatment and a nonsurgical UF treatment than their White counterparts; this may not be true for all women. Longer comparative effectiveness studies are needed to inform women about the durability of UF treatments. Greater understanding of factors influencing treatment selection is needed as are studies that include women without access to tertiary care centers.

Abstract Context. —Diffuse pulmonary hemorrhage is an uncommon presenting manifestation of angiosarcoma. Objective. —To review the clinical, radiologic, and pathologic findings of patients with metastatic angiosarcoma who presented with diffuse pulmonary hemorrhage. Design. —Patients fulfilling inclusion criteria were identified from the consultation files. Clinical and radiologic data were obtained from referring pathologists. Histologic slides were reviewed in all patients. Results. —Our patients included 6 men and 1 woman, aged 31 to 73 years; 4 patients were younger than 40 years. Six patients presented with hemoptysis, and all had diffuse abnormalities on radiographic studies. Clinical considerations prior to biopsy included pulmonary hemorrhage syndrome (n = 2), acute respiratory failure (n = 1), and infection (n = 1). Metastatic disease was included in the differential diagnosis in only 1 patient. None had a diagnosis of malignancy prior to lung biopsy. All biopsies showed hemorrhage associated with atypical epithelioid and spindle cells, forming anastomosing vascular channels, distributed along and within lymphatics and arteries. Neoplastic cells were immunoreactive for factor VIII–related protein or CD31 in all cases for which special stains were available. Three patients with complete follow-up died of their disease. Primary sites were discovered in all 3 patients who underwent autopsy examination. Two tumors arose in the heart and 1 in the pelvic soft tissues. One additional patient had a likely primary site identified in the right atrium by cardiac ultrasound and was subsequently lost to follow-up. Conclusion. —Angiosarcoma should be included in the differential diagnosis of diffuse pulmonary hemorrhage, especially in young adults.

Abstract We describe a patient with self-induced inhalational pulmonary talcosis originally diagnosed as asthma. A 35-year-old female respiratory technologist developed severe asthma that was refractory to steroids and methotrexate. An open lung biopsy specimen showed scattered aggregates of refractile golden crystals within membranous and respiratory bronchioles. The particles ranged in size from 30 to 100 μm and were birefringent when viewed with polarized light. Following review of the lung biopsy specimen, the patient admitted to regularly inhaling large amounts of hospital baby powder. Analysis of the lung biopsy specimen and a sample of the hospital baby powder by x-ray energy dispersion showed identical spectroscopic peaks, including elemental peaks for magnesium silicate. Many patients with self-induced illness lack the picturesque symptomatology classically attributed to Munchausen syndrome. Awareness of these more subtle and varied patterns of presentation may aid in earlier recognition.
