A Phase II Study of Midostaurin and 5-Azacitidine for Untreated Elderly and Unfit Patients With FLT3 Wild-type Acute Myelogenous Leukemia

BackgroundMidostaurin, a multikinase inhibitor, is approved for treatment of FLT3-mutant acute myeloid leukemia (AML). A phase I study established that midostaurin 75 mg orally twice daily for 14 days with standard dose azacitidine was safe and tolerable in elderly patients with AML. Herein, we report the phase II expansion cohort of previously untreated elderly or unfit patients with AML.Patients and MethodsPrimary objectives were to further describe the toxicity profile and determine the response rate in untreated patients with AML. Patients received midostaurin 75 mg orally twice daily on days 8 to 21 in combination with intravenous azacitidine at 75 mg/m² on days 1 to 7. Plasma inhibitory activity assay for FLT3 was performed pretreatment and on day 8 and day 15 of each cycle.ResultsTwenty-six patients (median age, 74 years; range, 59-85 years) with FLT3 wild-type AML were accrued. Patients received a median of 2 cycles of therapy (range, 1-10 cycles). Seven (29%) of 24 evaluable patients achieved a clinical response (4 complete response; 1 complete response with incomplete count recovery; and 2 partial response). The median overall survival was 244 days (95% confidence interval, 203-467 days). Hematologic, infectious, and gastrointestinal toxicities were comparable to similar studies. Peripheral blood FLT3 wild-type phosphorylation declined to 8% to 55% of pretreatment by day 15 of cycle 1 (7 patients) and declined with subsequent cycles (< 10% baseline) in 2 patients who were analyzed after cycle 3.ConclusionMultiple cycles of azacitidine and midostaurin were not well-tolerated, but persistent inhibition of FLT3 wild-type phosphorylation suggest intermittent dosing of midostaurin should be considered in future low-intensity regimens for FLT3-mutant AML.     

Effect of Exposure to Agent Orange on the Risk of Monoclonal Gammopathy and Subsequent Transformation to Multiple Myeloma: A Single-Center Experience From the Veterans Affairs Hospital,Detroit

BackgroundMonoclonal gammopathy of undetermined significance (MGUS) is an indolent, premalignant plasma cell disorder with the potential of transforming into symptomatic multiple myeloma (MM). There are multiple risk factors that contribute to transformation. Agent Orange (AO) has been linked with multiple malignant and nonmalignant conditions.Patients and MethodsWe conducted a retrospective chart review of patients with monoclonal gammopathy who were seen at John D. Dingell Veterans Affairs Medical Center (Detroit, Michigan) between 2005 and 2015 with MGUS, smoldering multiple myeloma, and MM. We explored baseline patient characteristics and explored AO exposure. Dates of diagnosis, dates of progression, and expiration dates were recorded to time to progression and overall survival (OS).ResultsWe identified 211 patients with monoclonal gammopathy; 96% were male and 122 were African American. Eleven patients had reported AO exposure. Cumulative risk of progression in the overall population was 1.4% at 1 year. Risk of transformation in the population exposed to AO was significantly higher with a hazard ratio (HR) of 11.19 (95% confidence interval [CI], 2.10-59.47; P = .005). OS was numerically shorter in AO-exposed patients with a median OS of 7 years compared with 11.1 years in those not exposed. However, AO exposure was not associated with OS in multivariable analysis (HR, 0.50; 95% CI, 0.07-3.83; P = .508).ConclusionMonoclonal gammopathy is a premalignant condition with the risk of progressing to MM. Exposure to AO has been implicated in multiple conditions including MM. Our study demonstrates an increased risk of progression in exposed patients.     

Differences in surgical resection rate and risk of malignancy in thyroid cytopathology practice between Western and Asian countries: A systematic review and meta-analysis

There is increasing evidence showing that clinicians employ different management strategies in their use of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). In this meta-analysis, we investigated the differences in diagnosis frequency, resection rate (RR), and risk of malignancy (ROM) between Western (ie, American and European) and Asian cytopathology practices. We searched PubMed and Web of Science from January 2010 to January 2019. Proportion and 95% CIs were calculated using a random-effect model. We used independent sample t tests to compare frequencies, RR, and ROM between Western and Asian practices. We analyzed a total of 38 studies with 145,066 fine-needle aspirations. Compared with Asian practice, Western series had a significantly lower ROM in most of TBSRTC categories, whereas the RR was not statistically different. Focusing on indeterminate nodules, the RR in Western series was significantly higher (51.3% vs 37.6%; P = .048), whereas the ROM was significantly lower (25.4% vs 41.9%; P = .002) compared with those in Asian series. The addition of Asian cohorts increased ROM for most of diagnostic categories compared with the original TBSRTC. In conclusion, this study demonstrates a difference in Western and Asian thyroid cytology practice, especially regarding the indeterminate categories. Lower RR and higher ROM suggest that Asian clinicians adopt a more conservative approach, whereas immediate diagnostic surgery is favored in Western practice for indeterminate nodules. The addition of Asian series into a meta-analysis of TBSRTC altered ROM for several categories, which should be considered in future revisions of TBSRTC.

Inhibiting Pathways Predicted From a Steroid Hormone Gene Signature Yields Synergistic Antitumor Effects in NSCLC

IntroductionMounting evidence supports a role for estrogen signaling in NSCLC progression. We previously reported a seven-gene signature that predicts prognosis in estrogen receptor β positive (ERβ+) NSCLC. The signature defines a network comprised of ER and human EGFR-2/3 (HER2/HER3) signaling.MethodsWe tested the efficacy of combining the pan-HER inhibitor, dacomitinib, with the estrogen antagonist, fulvestrant, in ERβ+ NSCLC models with differing genotypes. We assessed the potency of this combination on xenograft growth and survival of host mice, and the ability to reverse the gene signature associated with poor outcome.ResultsSynergy was observed between dacomitinib and fulvestrant in three human ERβ+ NSCLC models: 201T (wild-type EGFR), A549 (KRAS mutant), and HCC827 (EGFR 19 deletion) with combination indices of 0.1-0.6. The combination, but not single agents, completely reversed the gene signature associated with poor prognosis in a mechanism that is largely mediated by activator protein 1 downregulation. In vivo, the combination also induced tumor regression and reversed the gene signature. In HCC827 xenografts treated with the combination, survival of mice was prolonged after therapy discontinuation, tumors that recurred were less aggressive, and two mechanisms of HER inhibitor resistance involving c-Met activation and PTEN loss were blocked.ConclusionsThe combination of an ER blocker and a pan-HER inhibitor provides synergistic efficacy in different models of ERβ+ NSCLC. Our data support the use of this combination clinically, considering its ability to induce potent antitumor effects and produce a gene signature that predicts better clinical outcomes.

Éthique de la recherche : réglementations françaises et applications en oncologie radiothérapie

French regulations about research ethics are based on the so-called Jardé law, which defines researches involving human beings. Researches involving human beings require the submission of research protocols to a committee for protection of persons with a precise list of documents to submit for a favourable opinion. This law describes different categories of researches and determines the ethical procedures to apply before setting up a research protocol. This issue of categorisation is central and must be taken into account by researchers from the beginning of the research process. Researches considered as not involving human beings also require a set of ethical precautions focused on patients’ information and the collection of their non-opposition (due to the application of the General Data Protection Regulation adopted by the European Parliament). Thus, many regulations exist and they require a real work for researchers to meet these requirements in research ethics. This article aims to summarise French regulations. Selected examples are specifically taken into the field of radiation oncology research.
