Acquired von Willebrand's Syndrome in a Patient with Concomitant Chronic Lymphocytic Lymphoma and Smoldering Multiple Myeloma.

An African-American female in her sixties presented to the hospital with intermittent gum bleeding for the past two years along with severe anemia. This case details the differential and workup that lead to the diagnosis of acquired von Willebrand's syndrome (AvWS). A thorough investigation in the possible etiologies of AvWS revealed that the patient had concomitant chronic lymphocytic lymphoma (CLL) and smoldering multiple myeloma (SMM). Due to the concomitant diagnosis of CLL and SMM, there was a dilemma regarding whether CLL, SMM, or both was driving this patient's AvWS. Decision was made to treat the underlying CLL initially with rituximab and later on at recurrence with obinutuzumab/venetoclax with complete resolution of patient's bleeding and normalization of her factor VIII activity, von Willebrand factor antigen levels, and vWF:ristocetin cofactor levels. We believe this is first case in the literature of a patient with AvWS with concurrent CLL and SMM.

Analysis of Hematology and Oncology Fellowship Website Content and Diversity Representation.

PURPOSE: Hematology and oncology (HO) lags behind all medicine subspecialties in fellows under-represented in medicine (URM) despite a growing minority patient population. Websites have been effectively used in URM recruitment. We evaluated all US HO program websites to facilitate a more informed and URM-considerate recruitment. We also performed a stratified analysis on programs affiliated with National Cancer Institute (NCI) Designated Cancer Centers, National Comprehensive Cancer Center Network (NCCN) member institutions, and ranked as a top 50 cancer hospital by US News, given their stated commitment to outreach. MATERIALS AND METHODS: Websites of all 2019-2020 Accreditation Council for Graduate Medical Education-accredited HO programs were assessed for 28 informational and three diversity categories. Websites with > 70% of categories were comprehensive. Affiliation with NCI, NCCN, and US News was noted. RESULTS: One hundred fifty-six websites were analyzed: 20% were comprehensive and 22% had any diversity information. Inclusion of diversity content and being comprehensive were significantly associated (P = .001). NCI, NCCN, and US News ranking were significantly associated with inclusion of more information in univariate analyses (P < .001, P = .008, and P < .001, respectively). Multivariate analyses showed that US News ranking was significantly associated with more information (P = .005). Diversity-related univariate and multivariate analyses showed a significant association with US News ranking (P = .006 and P = .029, respectively). CONCLUSION: Most HO fellowship websites are not comprehensive and lack diversity content. Given COVID-19 travel restrictions limit in-person interviews, digital program presence remains an important opportunity. HO programs should offer comprehensive and inclusive websites to better inform applicants, including URM. This may increase institutional diversity and potentially improve URM representation in the HO workforce.

Critical Analysis of Hematology and Oncology Fellowship Web Sites in the United States.

PURPOSE: Prospective hematology-oncology fellowship applicants use program Web sites as a critical source of information. The purpose of this study was to evaluate the current content and comprehensiveness of hematology-oncology fellowship Web sites and to identify specific areas for improvement. METHODS: This study assessed the presence of 27 commonly evaluated program and application and curriculum and training informational items for Web sites of all accredited hematology-oncology fellowship programs in 2018. The comprehensiveness score was calculated as the number of items present on a fellowship Web site out of 27 and was compared by program region and size using analysis of variance and two-tailed t tests. RESULTS: Of the 143 fellowship Web sites evaluated, the mean comprehensiveness score was 39.3% (10.6 ± 3.8 out of 27). Programs contained a mean of 42.1% (5.9 ± 2.3 out of 14) of program and application and 36.2% (4.7 ± 2.1 out of 13) of curriculum and training items. The program and application items most common among Web sites were program coordinator contact and faculty listing (83.2% and 74.1% of Web sites, respectively), whereas social events and salary and benefits were less common (31.5% and 20.3% of Web sites, respectively). Prevalent curriculum and training items were research publications and activity and rotation scheduling (86.0% and 81.1% of Web sites, respectively), whereas board examination pass rates and fellow call duties were uncommon (4.2% and 15.4% of Web sites, respectively). Large programs were associated with greater overall Web site items compared with small programs (43.0% [11.6 ± 4.1 out of 27] v 35.9% [9.7 ± 3.3 out of 27]; P = .003). CONCLUSION: Hematology-oncology fellowship Web sites vary considerably in the level and nature of content they contain. Because applicants rely on online information for decision making, more comprehensive online content may promote a better fit between program and applicant. There is room for improvement in hematology-oncology fellowship Web sites, and programs may consider directing resources toward enhancing these Web sites.

Marrow Hypocellularity, But Not Residual Blast Count or Receipt of Reinduction Chemotherapy, Is Prognostic on Day-14 Assessment in Acute Myeloid Leukemia Patients With Morphologic Residual Disease.

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.

Informed consent in oncology clinical trials: A Brown University Oncology Research Group prospective cross-sectional pilot study.

BACKGROUND: Informed consent forms (ICFs) for oncology clinical trials have grown increasingly longer and more complex. We evaluated objective understanding of critical components of informed consent among patients enrolling in contemporary trials of conventional or novel biologic/targeted therapies. METHODS: We evaluated ICFs for cancer clinical trials for length and readability, and patients registered on those studies were asked to complete a validated 14-question survey assessing their understanding of key characteristics of the trial. Mean scores were compared in groups defined by trial and patient characteristics. RESULTS: Fifty patients, of whom half participated in trials of immunotherapy or biologic/targeted agents and half in trials of conventional therapy, completed the survey. On average, ICFs for industry-originated trials (N = 9 trials) were significantly longer (P < .0001) and had lower Flesch ease-of-reading scores (P = .003) than investigator-initiated trials (N = 11). At least 80% of patients incorrectly responded to three key questions which addressed the experimental nature of their trial therapy, its purported efficacy and potential risks relative to alternative treatments. The mean objective understanding score was 76.9±8.8, but it was statistically significantly lower for patients who had not completed high school (P = .011). The scores did not differ significantly by type of cancer therapy (P = .12) or trial sponsor (P = .38). CONCLUSIONS: Many participants enrolled on cancer trials had poor understanding of essential elements of their trial. In order to ensure true informed consent, innovative approaches, such as expanded in-person counseling adapted to the patient's education level or cultural characteristics should be evaluated across socio-demographic groups. TRIAL REGISTRATION: Clinicaltrials.gov NCT01772511.

Cellular immunotherapy for refractory hematological malignancies.

BACKGROUND: Acute myeloid leukemia (AML) and other aggressive refractory hematological malignancies unresponsive to upfront therapy remain difficult conditions to treat. Often, the focus of therapy is centered on achieving complete remission of disease in order to proceed with a consolidative stem cell transplant. At issue with this paradigm is the multitude of patients who are unable to achieve complete remission with standard chemotherapeutic options. A major benefit of transplantation is the graft versus tumor effect that follows successful engraftment. However, with this graft versus tumor effect comes the risk of graft versus host disease. Therefore, alternative treatment options that utilize immunotherapy while minimizing toxicity are warranted. Herein, we propose a novel treatment protocol in which haploidentical peripheral blood stem cells are infused into patients with refractory hematological malignancies. The end goal of cellular therapy is not engraftment but instead is the purposeful rejection of donor cells so as to elicit a potent immune reaction that appears to break host tumor tolerance. METHODS/DESIGN: The trial is a FDA and institutional Rhode Island Hospital/The Miriam Hospital IRB approved Phase I/II study to determine the efficacy and safety of haploidentical peripheral blood cell infusions into patients with refractory hematological malignancies. The primary objective is the overall response rate while secondary objectives will assess the degree and duration of response as well as safety considerations. Patients with refractory acute leukemias and aggressive lymphomas over the age of 18 are eligible. Donors will be selected amongst family members. Full HLA typing of patients and donors will occur as will chimerism assessments. 1-2x108 CD3+ cells/kilogram will be infused on Day 0 without preconditioning. Patients will be monitored for their response to therapy, in particular for the development of a cytokine release syndrome (CRS) that has been previously described. Blood samples will be taken at the onset, during, and following the cessation of CRS so as to study effector cells, cytokine/chemokine release patterns, and extracellular vesicle populations. Initially, six patients will be enrolled on study to determine safety. Provided the treatment is deemed safe, a total of 25 patients will be enrolled to determine efficacy. DISCUSSION: Cellular Immunotherapy for Refractory Hematological Malignancies provides a novel treatment for patients with relapsed/refractory acute leukemia or aggressive lymphoma. We believe this therapy offers the immunological benefit of bone marrow transplantation without the deleterious effects of myeloablative conditioning regimens and minus the risk of GVHD. Laboratory correlative studies will be performed in conjunction with the clinical trial to determine the underlying mechanism of action. This provides a true bench to bedside approach that should serve to further enrich knowledge of host tumor tolerance and mechanisms by which this may be overcome. TRIAL REGISTRATION: NCT01685606.
