Jérôme Bertherat, Aurélien de Reyniès and colleagues perform integrated genomic analyses of adrenocortical carcinomas. They discover recurrent alterations in several new driver genes, including ZNRF3 , DAXX , TERT and MED12 , and identify two distinct molecular subgroups with opposite clinical outcomes. Adrenocortical carcinomas (ACCs) are aggressive cancers originating in the cortex of the adrenal gland 1 . Despite overall poor prognosis, ACC outcome is heterogeneous 2 , 3 . We performed exome sequencing and SNP array analysis of 45 ACCs and identified recurrent alterations in known driver genes 4 , 5 ( CTNNB1 , TP53 , CDKN2A , RB1 and MEN1 ) and in genes not previously reported in ACC ( ZNRF3 , DAXX , TERT and MED12 ), which we validated in an independent cohort of 77 ACCs. ZNRF3 , encoding a cell surface E3 ubiquitin ligase 6 , was the most frequently altered gene (21%) and is a potential new tumor suppressor gene related to the β-catenin pathway. Our integrated genomic analyses further identified two distinct molecular subgroups with opposite outcome. The C1A group of ACCs with poor outcome displayed numerous mutations and DNA methylation alterations, whereas the C1B group of ACCs with good prognosis displayed specific deregulation of two microRNA clusters. Thus, aggressive and indolent ACCs correspond to two distinct molecular entities driven by different oncogenic alterations.

Lean body mass (LBM) is an important prognostic factor in patients with cancer. Although the L3–computed tomography (CT) scan is considered a reference method for assessment, a convenient and easily available method for longitudinal follow-up is required. Although bioelectrical impedance analysis (BIA) is widely used, its accuracy is questioned; plasma creatinine-to-cystatin C (CC) ratio could be an attractive alternative. The aim of this study was to evaluate the ability of the CC ratio and BIA to detect myopenia in patients with cancer compared with the use of the CT scan as a standard. Patients with any kind of cancer had body composition evaluation by CT scan, BIA, and CC. Statistical analysis included correlation test, Bland–Altman, and receiver operating characteristic curve analysis. Forty-four patients (14 women) were included. Of the participants, 59% had myopenia on CT scan. Both BIA LBM and CC ratio were well correlated with CT scan LBM (r = 0.763 and 0.648, respectively) but concordance analysis revealed a 3-kg constant bias toward BIA compared with CT scan. In terms of ability to detect myopenia, areas under the curve (AUC) for BIA were 0.675 and 0.388 for men and women, respectively. For CC ratio, AUCs were 0.813 and 0.673. This study demonstrated that LBM assessed by the CC ratio or BIA is well correlated with that determined by L3-CT scan. The ability of the CC ratio to detect myopenia was better than that of BIA. Findings from the present study demonstrated that CC ratio can be conveniently used in patients with cancer as a reliable biomarker of muscularity. •L3–computed tomography scan is most widely used for body composition evaluation in oncology.•L3–computed tomography scan for body composition in oncology has some shortcomings.•Bioimpedance analysis has a good correlation but poor agreement with L3–computed tomography scan.•The ratio of creatinine to cystatin C can be an alternative for the diagnosis of myopenia.

A large interindividual variability has been observed in anti Programmed cell Death 1 (anti-PD1) therapies efficacy. The aim of this study is to assess the correlation of soluble PD-1 (sPD-1), soluble Programmed cell Death Ligand 1 (sPD-L1), Vascular Endothelial Growth Factor A (VEGFA), soluble CD40 ligand (sCD40L) and soluble CD44 (sCD44), with survival in nivolumab-treated metastatic non-small cell lung cancer (NSCLC) patients. Plasma biomarkers were assayed at baseline and after two cycles of nivolumab. A cut-off of positivity for sPD-1, sPD-L1 and sCD40L expressions was defined as a plasma level above the lower limit of quantification. Baseline sPD-1 and sPD-L1 levels were subsequently analyzed in a control group of EGFR-mutated (Epidermal Growth Factor Receptor) NSCLC patients. Association between survival and biomarkers was investigated using Cox proportional hazard regression model. Eighty-seven patients were included (51 nivolumab-treated patients, 36 in EGFR-mutated group). In nivolumab group, baseline sPD-1, sPD-L1 and sCD40L were positive for 15(29.4%), 27(52.9%) and 18(50%) patients, respectively. We defined a composite criteria (sCombo) corresponding to sPD-1 and/or sPD-L1 positivity for each patient. In nivolumab group, baseline sCombo positivity was associated with shorter median progression-free survival (PFS) (78 days 95%CI (55–109) vs. 658 days (222-not reached); HR: 4.12 (1.95–8.71), p = 0.0002) and OS (HR: 3.99(1.63–9.80), p = 0.003). In multivariate analysis, baseline sCombo independently correlated with PFS (HR: 2.66 (1.17–6.08), p = 0.02) but not OS. In EGFR-mutated group, all patients were baseline sCombo positive; therefore this factor was not associated with survival. After two cycles of nivolumab, an increased or stable sPD-1 level independently correlated with longer PFS (HR: 0.49, 95%CI (0.30–0.80), p = 0.004) and OS (HR: 0.39, 95%CI (0.21–0.71), p = 0.002). VEGFA, sCD40L and sCD44 did not correlate with survival. We propose a composite biomarker using sPD-1and sPDL-1 to predict nivolumab efficacy in NSCLC patients. A larger validation study is warranted.

Abstract Background The prescription of antitumor drugs has often been associated with drug-related problems. Pretherapeutic multidisciplinary risk assessment programs including pharmaceutical care have been established to secure the initiation of injectable and oral antitumor therapies. This prospective cross-sectional double-center study evaluated the clinical and economic impact of the pharmacist in detecting drug-related problems in patients initiating antitumor therapies. Materials and Methods Following pharmaceutical consultations, pharmaceutical interventions were validated by a multidisciplinary team. A committee of independent clinical experts assessed the potential clinical impact of drug-drug interactions. The association of clinical variables with pharmaceutical interventions was tested using a multivariate logistic regression model. Pharmacist cost of the program was assessed by valuing pharmacists’ time at their salaries and compared with potentially avoided costs. Results Four hundred thirty-eight patients with solid tumors were included: 62% males, mean age of 65 ± 13 years, and average of 6 medications. Half of the patients required at least one pharmaceutical intervention and independent factors associated with pharmaceutical interventions were the number of medications (5-9 vs <5: OR = 2.91 [95% CI 1.82-4.65], P < .001) and the type of antitumor treatment (immunotherapy vs intravenous chemotherapy: OR = 0.35 [95% CI 0.18-0.68], P = .002). One hundred seventy-four out of 266 pharmaceutical interventions (130 patients) involved clinically significant drug-drug interactions. Pharmacist costs were estimated to range between €4899 and €6125. Average costs were estimated at €11.4-14.3 per patient. Avoided hospitalization costs were estimated to be €180 633. Conclusion Clinical pharmacists contribute to the cost-effective reduction of drug-related problems in pre-therapeutic assessment programs for patients with cancer. Pre-therapeutic multidisciplinary risk assessment programs including pharmaceutical care have been established to secure the initiation of injectable and oral antitumor therapies. This study evaluated the clinical and economic impact of the pharmacist in detecting drug-related problems in patients initiating antitumor therapies. Graphical Abstract Graphical Abstract

Summary Little is known on factors predicting toxicity of anti-PD1 checkpoint inhibitors. Sarcopenic obesity is associated with increased acute toxicity of cytotoxic agents and targeted therapies. We explored whether body composition also influenced the occurrence of early acute limiting toxicity (ALT) of anti-PD1 in melanoma patients. This is a monocentric, retrospective study analyzing toxicity outcome in consecutive melanoma patients treated with nivolumab or pembrolizumab. Various parameters linked to the patient or the disease status have been analysed. Body mass index (BMI; kg/m 2 ) and muscle mass using CT were measured prior to treatment initiation. Chi-squared test and Mann-Whitney’s tests were used for the comparison of categorical and continuous variables respectively. Among 68 melanoma patients treated with anti-PD1 (47 pembrolizumab, 21 nivolumab), 38 (56%) patients had a BMI ≥ 25 kg/m 2 and 11 (16%) a BMI ≥ 30, while 13 (19%) had both sarcopenia and a BMI ≥ 25 kg/m 2 . For the 11 (16%) patients who experienced early ALT, the mean BMI was higher (27.9 versus 24.7 kg/m 2 ; p  = 0.04). Among the 32 female patients, sarcopenic overweight patients had a 6.5-fold increased risk of ALT (50 versus 7.7%; p  = 0.01). Sarcopenic overweight is associated with more early ALT of anti-PD1 in melanoma patients.

Adrenocortical carcinomas (ACC) are aggressive and resistant to medical treatment. This study reports a single-nucleus transcriptome atlas of steroid and microenvironment cells in 38 human normal adrenals and adrenocortical tumors. We identify intermediate-state cells between glomerulosa and fasciculata, a transition state in the centripetal trans-differentiation of normal steroid cells. In tumors, steroid cells show expression programs reflecting this zonation. Although ACC microenvironment is scarce, its signatures combine with those of steroid cells into ecotypes. A first ecotype combines cancer-associated fibroblasts, tumor-associated endothelial cells, with hypoxia and mitosis signatures in steroid cells. Another ecotype combines exhausted T cells, with fasciculata steroid signature. These ecotypes are associated with poor survival. Conversely, a third ecotype combines inflammatory macrophages, with reticularis steroid signature, and better outcome. These steroid/microenvironment cells interplays improve outcome predictions and may open therapeutic options in aggressive ACC, through immune microenvironment activation by modulating glucocorticoids/androgens balance. Adrenocortical carcinomas (ACC) are aggressive and often resistant to therapy. Here, the authors provide a single-nucleus transcriptomic atlas of ACCs and normal adrenal glands, finding ecotypes in steroid and microenvironment cells that are associated with clinical outcomes.

Background Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH) is a rare cause of Cushing’s syndrome due to bilateral adrenocortical macronodules. Germline inactivating variants of the tumor suppressor gene ARMC5 are responsible for 20–25% of apparently sporadic PBMAH cases and 80% of familial presentations. ARMC5 screening is now routinely performed for PBMAH patients and families. Based on literature review and own observation, this study aims to give an overview of both published and unpublished ARMC5 genetic alterations and to compile the available evidence to discriminate pathogenic from benign variants. Results 146 different germline variants (110 previously published and 36 novel) are identified, including 46% missense substitutions, 45% truncating variants, 3% affecting splice sites, 4% in-frame variants and 2% large deletions. In addition to the germline events, somatic 16p loss-of-heterozygosity and 104 different somatic events are described. The pathogenicity of ARMC5 variants is established on the basis of their frequency in the general population, in silico predictions, familial segregation and tumor DNA sequencing. Conclusions This is the first extensive review of ARMC5 pathogenic variants. It shows that they are spread on the whole coding sequence. This is a valuable resource for genetic investigations of PBMAH and will help the interpretation of new missense substitutions that are continuously identified.

Little is known about immune checkpoint inhibitors (ICI) response of NF1 -mutated lung adenocarcinomas. 341/4,181 (8.2%) TCGA lung adenocarcinomas samples have a somatic NF1 mutation. NF1 -mutated tumors have higher TMB ( p  < 0.0001), higher expression of immune genes (“hot phenotype”) and higher CD8 + T cell ( p  = 0.03) and macrophage ( p  = 0.02) infiltrations compared to NF1 wild-type tumors. NF1 mutation status appears as a candidate predictive biomarker for ICI response in lung adenocarcinoma patients.

Prostate cancer is one of the most commonly diagnosed cancers in men. A number of genomic and clinical studies have led to a better understanding of prostate cancer biology. Still, the care of patients as well as the prediction of disease aggressiveness, recurrence and outcome remain challenging. Here, we showed that expression of the gene ZBTB38 is associated with poor prognosis in localised prostate cancer and could help discriminate aggressive localised prostate tumours from those who can benefit only from observation. Analysis of different prostate cancer cohorts indicates that low expression levels of ZBTB38 associate with increased levels of chromosomal abnormalities and more aggressive pathological features, including higher rate of biochemical recurrence of the disease. Importantly, gene expression profiling of these tumours, complemented with cellular assays on prostate cancer cell lines, unveiled that tumours with low levels of ZBTB38 expression might be targeted by doxorubicin, a compound generating reactive oxygen species. Our study shows that ZBTB38 is involved in prostate cancer pathogenesis and may represent a useful marker to identify high risk and highly rearranged localised prostate cancer susceptible to doxorubicin.

BackgroundThe risk of drug–drug interactions (DDI) has become a major issue in cancer patients. However, data in sarcoma patients are scarce. We aimed to evaluate the frequency and the factors associated with DDI with antitumor treatments, and to evaluate the impact of a pharmacist evaluation before anticancer treatment.Patients and methodsWe performed a retrospective review of consecutive sarcoma patients starting chemotherapy (CT) or Tyrosine kinase inhibitor (TKI). A pharmacist performed medication reconciliation and established an early toxicity risk assessment. Potential DDI with antitumor drugs were identified using Micromedex electronic software.ResultsOne hundred and twenty-two soft-tissue and 80 bone sarcoma patients (103 males, median age 50 years,) were included before CT (86%) or TKI (14%). The median number of medications was 3; 34 patients (22% of patients with medication reconciliation) reported complementary medicine use. 37 potential DDI classified as major, were identified (12% of the 243 pre-therapeutic assessments). In multivariate analysis, TKI (p < 0.0001), proton pump inhibitor (p = 0.026) and antidepressant (p < 0.001) were identified as risk factors of DDI (p < 0.02). Only marital status (p = 0.003) was associated with complementary medicine use. A pharmacist performed 157 medication reconciliations and made 71 interventions among 59 patients (37%). In multivariate analysis, factors associated with pharmacist intervention were: complementary medicines (p = 0.004), drugs number (p = 0.005) and treatment with TKI (p = 0.0002)ConclusionsClinical interventions on DDI are more frequently required among sarcoma patients treated with TKI than CT. Multidisciplinary risk assessment including a medication reconciliation by a pharmacist could be crucial to prevent DDI with TKI.
