RESUMEN

INTRODUCTION: Acquired haemophilia A (AHA) is a rare and potentially life-threatening bleeding disorder arising from autoantibodies that inhibit coagulation factor VIII (FVIII). Treatment entails achieving haemostasis with bypassing agents or factor replacement, and eradication of the inhibitor with immunosuppressive therapy (IST). Due to the rarity of AHA, there are few prospective data to guide management. METHODS: We present a retrospective report of 11 AHA patients treated with emicizumab, a FVIII-mimetic bispecific antibody, administered at 3 mg/kg weekly for 4 weeks in conjunction with rituximab-based immunosuppressive therapy. The chromogenic FVIII inhibitor assay was used to assess for inhibitor eradication. RESULTS: The median follow-up was 13.9 months. The median number of days of additional haemostatic therapy or red blood cell transfusions after initiating emicizumab was 2 (range 0-15). The median was 0 days (range 0-8) for patients who did not require vascular embolization to achieve haemostasis. Eight patients achieved a complete remission (defined as recovery of FVIII activity to > 50% with a negative inhibitor test in the absence of haemostatic and IST); two patients achieved a partial remission (FVIII activity > 50% but with detectable inhibitor); one patient experienced refractory disease. One patient experienced rebleeding and two patients experienced inhibitor recurrence. No thrombotic, thrombotic microangiopathic or infectious complications occurred. CONCLUSION: Our observations suggest emicizumab can facilitate haemostasis for AHA patients and be combined with safer, lower-intensity immunosuppressive therapies to achieve remission.

RESUMEN

Gene therapy (GT) has been reported to improve bone marrow function in individuals with Fanconi anemia (FA); however, its clinical application is still in the initial stages. We conducted this systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to assess the long-term safety and clinical outcomes of GT in FA patients. Electronic searches from PubMed, Web of Science, Cochrane Library, and Google Scholar were conducted and full texts of articles meeting our inclusion criteria were reviewed. Three clinical trials were included, with a total of nine patients and mean age of 10.7 ±â€¯5.7 years. All patients had lentiviral-mediated GT. A 1-year follow-up showed stabilization in blood lineages, without any serious adverse effects from GT. A metaregression analysis could not be conducted, as very little long-term follow-up data of patients was observed, and the median survival rate could not be calculated. Thus, we can conclude that GT seems to be a safe procedure in FA; however, further research needs to be conducted on the longitudinal clinical effects of GT in FA, for a better insight into its potential to become a standard form of treatment.

RESUMEN

The coronavirus disease (COVID)-19 pandemic has affected graduate medical education training programs, including hematology-oncology fellowship programs, both across the United States and abroad. Within the Dana-Farber Cancer Institute/Mass General Brigham hematology-oncology fellowship program, fellowship leadership had to quickly reorganize the program's clinical, educational, and research structure to minimize the risk of COVID-19 spread to our patients and staff, allow fellows to assist in the care of patients with COVID-19, maintain formal didactics despite physical distancing, and ensure the mental and physical well-being of fellows. Following the first wave of patients with COVID-19, we anonymously surveyed the Dana-Farber Cancer Institute/Mass General Brigham first-year fellows to explore their perceptions regarding what the program did well and what could have been improved in the COVID-19 response. In this article, we present the feedback from our fellows and the lessons we learned as a program from this feedback. To our knowledge, this represents the first effort in the hematology-oncology literature to directly assess a hematology-oncology program's overall response to COVID-19 through direct feedback from fellows.

RESUMEN

Chemotherapy-induced thrombocytopenia (CIT) frequently complicates cancer treatment causing chemotherapy delays, dose reductions, and discontinuation. There is no FDA-approved agent available to manage CIT. This study retrospectively evaluated patients with CIT treated on institutional romiplostim treatment pathways at 4 U.S. centers. The primary outcome was achievement of a romiplostim response [median on-romiplostim platelet count (Plt) ≥75x109/L and ≥30x109/L above baseline]. Secondary outcomes included time to Plt≥100x109/L and rates of the following: Plt<100x109/L, Plt<75x109/L, Plt<50x109/L, thrombocytosis, chemotherapy dose reduction/treatment delay, platelet transfusion, bleeding, and thromboembolism. Multivariable regression was used to identify predictors of romiplostim non-response and compare weekly dosing with intracycle/intermittent dosing. 173 patients (153 solid tumor, 20 lymphoma or myeloma) were treated, with 170 (98%) receiving a median of 4 (range, 1-36) additional chemotherapy cycles on romiplostim. Romiplostim was effective in solid tumor patients: 71% of patients achieved a romiplostim response, 79% avoided chemotherapy dose reductions/treatment delays and 89% avoided platelet transfusions. Median per-patient Plt on romiplostim was significantly higher than baseline (116x109/L vs. 60x109/L, P<0.001). Bone marrow tumor invasion, prior pelvic irradiation, and prior temozolomide predicted romiplostim non-response. Bleeding rates were lower than historical CIT cohorts and thrombosis rates were not elevated. Weekly dosing was superior to intracycle dosing with higher response rates and less chemotherapy dose reductions/treatment delays (IRR 3.00, 95% CI 1.30-6.91, P=0.010) or bleeding (IRR 4.84, 95% CI 1.18-19.89, P=0.029). Blunted response (10% response rate) was seen in non-myeloid hematologic malignancy patients with bone marrow involvement. In conclusion, romiplostim was safe and effective for CIT in most solid tumor patients.

RESUMEN

OBJECTIVE: The objective of this study was to examine the religious/spiritual beliefs of followers of the five major world religions about frequently encountered medical situations at the end of life (EoL). METHOD: This was a systematic review of observational studies on the religious aspects of commonly encountered EoL situations. The databases used for retrieving studies were: Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid PsycINFO, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus. Observational studies, including surveys from healthcare providers or the general population, and case studies were included for review. Articles written from a purely theoretical or philosophical perspective were excluded. RESULTS: Our search strategy generated 968 references, 40 of which were included for review, while 5 studies were added from reference lists. Whenever possible, we organized the results into five categories that would be clinically meaningful for palliative care practices at the EoL: advanced directives, euthanasia and physician-assisted suicide, physical requirements (artificial nutrition, hydration, and pain management), autopsy practices, and other EoL religious considerations. A wide degree of heterogeneity was observed within religions, depending on the country of origin, level of education, and degree of intrinsic religiosity. SIGNIFICANCE OF RESULTS: Our review describes the religious practices pertaining to major EoL issues and explains the variations in EoL decision making by clinicians and patients based on their religious teachings and beliefs. Prospective studies with validated tools for religiosity should be performed in the future to assess the impact of religion on EoL care.

RESUMEN

The family of epidermal growth factor receptors (EGFRs) is overexpressed in many gynecologic malignancies. Extensive preclinical studies of these receptors demonstrate that they play an important role in supporting the growth of a wide variety of malignancies and that interruption of receptor function or signaling from these receptors leads to inhibition of tumor growth or in certain cases tumor regression. Recently, many therapeutic agents targeting this receptor have entered the clinic and phase II clinical studies have demonstrated activity in lung cancer, colon cancer, and head and neck malignancies. Phase II trials of both small molecule inhibitors of EGFR and antibody-based inhibitors are underway in both cervical and ovarian cancer and emerging data suggests that their activity in unselected women with advanced gynecologic malignancies is very modest. Recently, molecular analysis of lung cancers has identified that the response to small molecule inhibitors of EGFR is highly correlated with activating mutations within the EGFR. It is possible that these agents will be highly effective in a small subset of patients with gynecologic malignancies whose tumors are dependent on EGFR signaling, perhaps through an activating mutation in EGFR or its downstream pathway. Until additional research can identify the subset of patients most likely to benefit from this targeted therapy, treatment for women with gynecologic malignancies with EGFR inhibitors should be limited to investigational trials. It is critical that these trials have access to tissue of responding and nonresponding patients so to determine the rational use of these agents in the treatment of gynecologic malignancies.
