RESUMO

BACKGROUND: Voriconazole treatment increases early survival of allogeneic hematopoietic stem cell transplant recipients with invasive aspergillosis. We investigated whether this survival advantage translates into an increased long-term survival. DESIGN AND METHODS: This retrospective study involved all patients with an invasive aspergillosis diagnosis transplanted between September 1997 and December 2008, at the Saint-Louis Hospital, Paris, France. The primary end point was survival up to 36 months. Survival analysis before and after 12 weeks, as well as cumulative incidence analysis in a competing risk framework, were used to assess the effect of voriconazole treatment and other factors on mortality. RESULTS: Among 87 patients, 42 received first-line voriconazole and 45 received another antifungal agent. Median survival time was 2.6 months and survival rate at 36 months was 18%. Overall, there was a significant difference in the survival rates of the two groups. Specifically, there was a dramatic difference in survival rates up to ten months post-aspergillosis diagnosis but no significant difference after this time. Over the first 36 months as a whole, no significant difference in survival rate was observed between the two groups. First-line voriconazole significantly reduced aspergillosis-attributable mortality. However, first-line voriconazole patients experienced a significantly higher probability of death from a non-aspergillosis-attributable cause. CONCLUSIONS: Although the prognosis for invasive aspergillosis after stem cell transplantation has dramatically improved with the use of voriconazole, this major advance in care does not translate into increased long-term survival for these severely immunocompromised patients.

RESUMO

PURPOSE: To provide insights into the diagnosis and management of therapy-related myeloid neoplasms (t-MN) following PARP inhibitors (PARPi). EXPERIMENTAL DESIGN: In a French cancer center, we identified and described the profiles of 13 t-MN diagnosed among 37 patients with ovarian cancer referred to hematology consultation for cytopenia under PARPi. Next, we described these 13 t-MN post-PARPi among 37 t-MN post ovarian cancer according to PARPi exposure. Finally, we described 69 t-MN post-PARPi in a national cohort. RESULTS: From 2016 to 2021, cumulative incidence of t-MN was 3.5% (13/373) among patients with ovarian cancer treated with PARPi. At time of hematologic consultation, patients with t-MN had a longer PARPi exposure (9 vs. 3 months, P = 0.01), lower platelet count (74 vs. 173 G/L, P = 0.0005), and more cytopenias (2 vs. 1, P = 0.0005). Compared with t-MN not exposed to PARPi, patients with t-MN-PARPi had more BRCA1/2 germline mutation (61.5% vs. 0%, P = 0.03) but similar overall survival (OS). In the national cohort, most t-MN post-PARPi had a complex karyotype (61%) associated with a high rate of TP53 mutation (71%). Median OS was 9.6 months (interquartile range, 4-14.6). In multivariate analysis, a longer time between end of PARPi and t-MN (HR, 1.046; P = 0.02), olaparib compared with other PARPi (HR, 5.82; P = 0.003) and acute myeloid leukemia (HR, 2.485; P = 0.01) were associated with shorter OS. CONCLUSIONS: In a large series, we described a high incidence of t-MN post-PARPi associated with unfavorable cytogenetic and molecular abnormalities leading to poor OS. Early detection is crucial, particularly in cases of delayed cytopenia.

RESUMO

Autoimmune hemolytic anemia (AIHA) has been associated with chronic lymphocytic leukemia, non-Hodgkin lymphoma, and classical Hodgkin lymphoma, but to the best of our knowledge, the association of AIHA and nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) has not been reported previously. A 20-year-old woman presented with conjunctival jaundice, fever, asthenia, and hemoglobin 9.2 g/dL revealing IgG-mediated warm antibody AIHA. Computed tomography (CT) scan and positron-emission tomography (PET) scan showed mediastinal and axillary lymph nodes with increased [(18)F]-fluorodeoxyglucose uptake. A mediastinal lymph node was biopsied during mediastinoscopy, and NLPHL was diagnosed by an expert hematopathologist. The hemoglobin level declined to 4.6 g/dL. The treatment consisted of four 28-day cycles of R-ABVD (rituximab 375 mg/m(2) IV, adriamycin 25 mg/m(2) IV, bleomycin 10 mg/m(2) IV, vinblastine 6 mg/m(2) IV, and dacarbazine 375 mg/m(2) IV, each on days 1 and 15). Prednisone was progressively tapered over 10 weeks. After the first chemotherapy cycle, the hemoglobin level rose to 12 g/dL. After the four cycles, PET and CT scans showed complete remission (CR). At the last followup (4 years), AIHA and NLPHL were in sustained CR.
