RESUMEN
OBJECTIVES: To evaluate the performance of artificial intelligence (AI) in the preoperative detection of lung metastases on CT. MATERIALS AND METHODS: Patients who underwent lung metastasectomy in our institution between 2016 and 2020 were enrolled, their preoperative CT reports having been performed before an AI solution (Veye Lung Nodules, version 3.9.2, Aidence) became available as a second reader in our department. All CT scans were retrospectively processed by AI. The sensitivities of unassisted radiologists (original CT radiology reports), AI reports alone and both combined were compared. Ground truth was established by a consensus reading of two radiologists, who analyzed whether the nodules mentioned in the pathology report were retrospectively visible on CT. Multivariate analysis was performed to identify nodule characteristics associated with detectability. RESULTS: A total of 167 patients (men: 62.9 %; median age, 59 years [47-68]) with 475 resected nodules were included. AI detected an average of 4 nodules (0-17) per CT, of which 97 % were true nodules. The combination of radiologist plus AI (92.4 %) had significantly higher sensitivity than unassisted radiologists (80.4 %) (p < 0.001). In 27/57 (47.4 %) patients who had multiple preoperative CT scans, AI detected lung nodules earlier than the radiologist. Vascular contact was associated with non-detection by radiologists (OR:0.32[0.19, 0.54], p < 0.001), whilst the presence of cavitation (OR:0.26[0.13, 0.54], p < 0.001) or pleural contact (OR:0.10[0.04, 0.22], p < 0.001) was associated with non-detection by AI. CONCLUSION: AI significantly increases the sensitivity of preoperative detection of lung metastases and enables earlier detection, with a significant potential benefit for patient management.

BACKGROUND: Reducing nivolumab dose intensity could increase patients' life quality and decrease the financial burden while maintaining efficacy. The aims of this study were to develop a population PK model of nivolumab based on data from unselected metastatic cancer patients and to simulate extended-interval regimens allowing to maintain minimal effective plasma concentrations (MEPC). METHODS: Concentration-time data (992 plasma nivolumab concentrations, 364 patients) were modeled using a two-compartment model with linear elimination clearance in Monolix software. Extended-interval regimens allowing to maintain steady-state trough concentrations (Cmin,ss) above the MEPC of 2.5 mg/L or 1.5 mg/L in >90% of patients were simulated. RESULTS: Increasing 3-times the dosing interval from 240 mg every two weeks (Q2W) to Q6W and 2-times from 480 mg Q4W to Q8W resulted in Cmin,ss above 2.5 mg/L in 95.8% and 95.4% of patients, respectively. 240 mg Q8W and 480 mg Q10W resulted in Cmin,ss above 1.5 mg/L in 91.0% and 91.8% of patients, respectively. Selection of a 240 mg Q6W regimen would decrease by 3-fold the annual treatment costs compared to standard regimen of 240 mg Q2W (from 78,744 to 26,248 in France). CONCLUSIONS: Clinical trials are warranted to confirm the non-inferiority of extended-interval compared to standard regimen.

OBJECTIVE: To assess the prognostic value of neurocognitive disorder (NCD) for 12 month-overall mortality in patients aged 70 or more with a solid cancer. DESIGN: prospective, observational, multicenter cohort. SETTING AND PARTICIPANTS: We analyzed data from the ELCAPA longitudinal multicenter observational cohort of patients aged 70 or over, referred for a geriatric assessment (GA) before a new cancer treatment modality between January 31st, 2007, and December 29th, 2017. We defined the baseline NCD in four classes: no NCD, mild NCD, moderate NCD, and major NCD, based on the Mini-Mental State Examination (MMSE) score, memory complaint, and the Instrumental Activities of Daily Living (IADL) score. STATISTICAL METHODS: We compared the baseline characteristics of patients according to NCD classes, globally and by pairs (with Bonferroni' correction). Prognosis value of NCD classes were analysed by using univariable and then multivariable 12 month survival analysis with age as time-variable and with and without adjustement for the treatment strategy (curative, palliative or exclusive supportive care). RESULTS: 2784 patients with solid-cancer were included, with a median [interquartile range] age of 82 [78;86]. 36% of the patients were free of NCD, 34% had a mild NCD, 17% had a moderate NCD, and 13% had a major NCD. We identified the following independent prognostic factors for 12 month-overall mortality: NCD (adjusted hazard ratio (aHR) [95% confidence interval (CI)] for a major NCD = 1.54 [1.19-1.98] (p < 0.001), type of cancer, metastatic status, inpatient consultation, poor general health (assessed as the level of fatigue and Eastern Cooperative Oncology Group performance status [ECOG-PS]), greater weight loss, palliative treatment, and exclusive supportive care. Additional adjustment for the treatment strategy did not greatly change the strength of the association of a major NCD with 12 month-overall mortality (HR [95%CI] = 1.78 [1.39-2.29] (p < 0.001). CONCLUSION: Our results suggest that the presence of a major NCD has direct prognostic value (independently of other geriatric factors, the type of cancer and the treatment strategy) in older patients with a solid cancer.

OBJECTIVES: The primary objective of the present study was to evaluate and compare the ability of eight nutrition-related tools to predict 1-year mortality in older patients with cancer. DESIGN, SETTING AND PARTICIPANTS: We studied older patients with cancer from the ELCAPA cohort and who had been referred for a geriatric assessment at one of 14 participating geriatric oncology clinics in the greater Paris area of France between 2007 and 2018. MEASUREMENTS: The studied nutrition-related tools/markers were the body mass index (BMI), weight loss (WL) in the previous 6 months, the Mini Nutritional Assessment, the Geriatric Nutritional Risk Index (GNRI), the Prognostic Nutritional Index, the Glasgow Prognostic Score (GPS), the modified GPS, and the C-reactive protein/albumin ratio. RESULTS: A total of 1361 patients (median age: 81; males: 51%; metastatic cancer: 49%) were included in the analysis. Most of the tools showed a progressively increase in the mortality risk as the nutrition-related risk category worsened (overall p-values <0.02 for all) after adjustment for age, outpatient status, functional status, severe comorbidities, cognition, mood, cancer treatment strategy, tumour site, and tumour metastasis. All the models were discriminant, with a C-index ranging from 0.748 (for the BMI) to 0.762 (for the GPS). The concordance probability estimate ranged from 0.764 (WL) to 0.773 (GNRI and GPS)). CONCLUSION: After adjustment for relevant prognostic factors, all eight nutrition-related tools/markers were independently associated with 1-year mortality in older patients with cancer. Depending on the time or context of the GA, physicians do not always have the time or means to perform and assess all the tools/markers compared here. However, even when some information is missing, each nutritional tool/marker has prognostic value and can be used in the evaluation.

PURPOSE: Pazopanib is approved in advanced renal cell carcinoma (RCC) and soft-tissue sarcoma at a flat-fixed dose despite a large pharmacokinetics interindividual variability and a narrow therapeutic index. To our knowledge, pazopanib exposure in patients with gastrointestinal resections (GIR) has not been described. This report focuses on feasibility of pharmacokinetics-guided dose escalation in these patients and clinical implications for their management. METHOD: A retrospective data collection was performed for three patients with GIR treated with pazopanib, including pazopanib plasma concentrations (high-performance liquid chromatography with UV detection) and treatment adherence (Girerd score). CASE PRESENTATION: First patient (55-year-old man, RCC, gastric bypass surgery) pazopanib Cmin,ss at day 39 was 4.1 mg/L. Dose escalation to 1800 mg/day fractionated allowed to reach Cmin,ss of 18.5 mg/L (target threshold in RCC patients: 20.5 mg/L). Patient 2 (50-year-old woman, metastatic myxofibrosarcoma, gastric band) showed Cmin,ss of 4.0 mg/L at day 13. In patient 3 (49-year-old man, gastric malignant peripheral nerve sheath tumor, gastrectomy), Cmin,ss at day 13 was 2.7 mg/L. For these two patients, intake with food and dose fractioning only slightly increased pazopanib Cmin,ss to 12.0 mg/L and 6.5 mg/L, respectively (therapeutic threshold in sarcoma patients: 27 mg/L). Treatment adherence was good in all patients. CONCLUSION: Optimal pazopanib exposure cannot be achieved in patients with GIR, and thus, other therapeutic strategies should be encouraged. Pretherapeutic assessment seems crucial to evaluate factors as bariatric surgery that may impact pazopanib concentrations. Therapeutic drug monitoring could be helpful to optimize pazopanib response in these patients.

EBV-positive inflammatory follicular dendritic cell sarcoma (EBV+ inflammatory FDCS) is a rare neoplasm almost exclusively located in the spleen or liver. It is characterized by a proliferation of EBV-positive spindle-shaped cells bearing follicular dendritic cell markers, associated with an abundant lymphoplasmacytic infiltrate. EBV+ inflammatory FDCS is often asymptomatic or responsible for mild symptoms. It usually displays an indolent course and its prognosis is excellent after tumor removal, although relapsing and metastatic forms exist. Herein, we describe an aggressive form of splenic EBV+ inflammatory FDCS in a 79-year-old woman presenting with abdominal pain, deterioration of general health status, major inflammatory syndrome, and symptomatic hypercalcemia. A splenectomy was performed leading to a rapid improvement in her clinical condition and normalization of laboratory abnormalities. Unfortunately, her symptoms and laboratory abnormalities reappeared 4 months later. Computed tomography showed a mass in the splenectomy site and multiple liver and peritoneal nodules. Further analyses were performed on tumor tissue and showed positive phospho-ERK staining of tumoral cells indicating activation of MAPK pathway. Inactivating mutations were found on CDKN2A and NF1 genes. Subsequently, the patient's condition deteriorated rapidly. Since interleukin-6 levels were dramatically increased, tocilizumab was used but only had a transient effect on the patient's symptoms and inflammatory syndrome. Antitumor agent gemcitabine was initiated but her clinical condition continued to deteriorate and the patient died 2 weeks later. The management of aggressive forms of EBV+ inflammatory FDCS remains challenging. However, since these tumors seem to display genetic alterations, better characterization could lead to molecular targeted therapies.

BACKGROUND: The REGOBONE multi-cohort study explored the efficacy and safety of regorafenib for patients with advanced bone sarcomas; this report details the Ewing sarcoma (ES) cohort. METHODS: Patients with relapsed ES progressing despite prior standard therapy, were randomised (2:1) to receive regorafenib or placebo. Patients on placebo could crossover to receive regorafenib after centrally confirmed progression. The primary endpoint was the progression-free rate at 8 weeks. With one-sided α of 0.05, and 80% power, at least 14/24 progression-free patients at 8 weeks were needed for success. RESULTS: From September 2014 to November 2019, 41 patients were accrued. 36 patients were evaluable for efficacy: 23 on regorafenib and 13 on placebo. Thirteen patients (56%; one-sided 95% CI [37.5%-[)) were progression-free at 8 weeks on regorafenib vs. 1 (7.7%; 95% CI [0.4%-[) on placebo. Median PFS was 11.4 weeks on regorafenib, and 3.9 weeks on placebo. Ten placebo patients crossed over to receive regorafenib after progression. The most common grade ≥3 regorafenib-related adverse events were pain (22%), asthenia (17%), thrombocytopenia (13%) and diarrhoea (13%). CONCLUSION: Although the primary endpoint was not met statistically in this randomised cohort, there is evidence to suggest that regorafenib might modestly delay tumour progression in relapsed ES after failure of prior chemotherapy.

BACKGROUND/OBJECTIVE: To analyze changes in recurrent/refractory osteosarcoma phase II trials over time to inform future trials in this population with poor prognosis. METHODS: A systematic review of trials registered on trial registries between 01/01/2017-14/02/2022. Comparison of 98 trials identified between 2003 and 2016. Publication search/analysis for both periods, last update on 01/12/2022. RESULTS: Between 2017 and 2022, 71 phase-II trials met our selection criteria (19 osteosarcoma-specific trials, 14 solid tumor trials with and 38 trials without an osteosarcoma-specific stratum). The trial number increased over time: 13.9 versus 7 trials/year (p = 0.06). Monotherapy remained the predominant treatment (62% vs. 62%, p = 1). Targeted therapies were increasingly evaluated (66% vs. 41%, P = 0.001). Heterogeneity persisted in the trial characteristics. The inclusion criteria were measurable disease (75%), evaluable disease (14%), and surgical remission (11%). 82% of the trials included pediatric or adolescent patients. Biomarker-driven trials accounted for 25% of the total trials. The survival endpoint use (rather than response) slightly increased (40% versus 31%), but the study H1/H0 hypotheses remained heterogeneous. Single-arm designs predominated over multiarm trials (n = 7). Available efficacy data on 1361 osteosarcoma patients in 58 trials remained disappointing, even though 21% of these trials were considered positive, predominantly those evaluating multi-targeted kinase inhibitors. CONCLUSION: Despite observed changes in trial design and an increased number of trials investigating new therapies, high heterogeneity remained with respect to patient selection, study design, primary endpoints, and statistical hypotheses in recently registered phase II trials for osteosarcoma. Continued optimization of trial design informed by a deeper biological understanding should strengthen the development of new therapies.
RESUMEN
BACKGROUND: Anti-PD1/PDL1 immune checkpoint inhibitors (ICI) transformed the prognosis of patients with advanced non-small cell lung cancer (NSCLC). However, the response rate remains disappointing and toxicity may be life-threatening, making urgent identification of biomarkers predictive for efficacy. Immunologic Constant of Rejection signature (ICR) is a 20-gene expression signature of cytotoxic immune response with prognostic value in some solid cancers. Our objective was to assess its predictive value for benefit from anti-PD1/PDL1 in patients with advanced NSCLC. METHODS: We retrospectively profiled 44 primary tumors derived from NSCLC patients treated with ICI as single-agent in at least the second-line metastatic setting. Transcriptomic analysis was performed using the nCounter® analysis system and the PanCancer Immune Profiling Panel. We then pooled our data with clinico-biological data from four public gene expression data sets, leading to a total of 162 NSCLC patients treated with single-agent anti-PD1/PDL1. ICR was applied to all samples and correlation was searched between ICR classes and the Durable Clinical Benefit (DCB), defined as stable disease or objective response according to RECIST 1.1 for a minimum of 6 months after the start of ICI. RESULTS: The DCB rate was 29%; 22% of samples were classified as ICR1, 30% ICR2, 22% ICR3, and 26% ICR4. These classes were not associated with the clinico-pathological variables, but showed enrichment from ICR1 to ICR4 in quantitative/qualitative markers of immune response. ICR2-4 class was associated with a 5.65-fold DCB rate when compared with ICR1 class. In multivariate analysis, ICR classification remained associated with DCB, independently from PDL1 expression and other predictive immune signatures. By contrast, it was not associated with disease-free survival in 556 NSCLC TCGA patients untreated with ICI. CONCLUSION: The 20-gene ICR signature was independently associated with benefit from anti-PD1/PDL1 ICI in patients with advanced NSCLC. Validation in larger retrospective and prospective series is warranted.

BACKGROUND: Sarcoma is a heterogeneous group of diseases with few treatment options. Immunotherapy has shown little activity in studies including unselected sarcomas, but immune checkpoint blockers have shown activity in specific histotypes. We evaluated the activity of pembrolizumab in rare and ultra-rare sarcomas. METHODS: AcSé Pembrolizumab is an ongoing phase 2, basket, multitumour study investigating the activity of pembrolizumab monotherapy in rare cancers. Here, we report the results obtained in patients with selected histotypes of rare sarcomas (incidence of less than one case per 1 000 000 people per year) recruited at 24 French hospitals. Key inclusion criteria were age 15 years or older, Eastern Cooperative Oncology Group performance status of 0-1, and advanced disease that was untreated and resistant to treatment. Patients were given pembrolizumab 200 mg intravenously on day 1 of every 21-day cycle for a maximum of 24 months. The primary endpoint was objective response rate at week 12 using Response Evaluation Criteria in Solid Tumours version 1.1, assessed by local investigators. The primary endpoint and safety were analysed in the intention-to-treat population. The AcSé Pembrolizumab study is registered with ClinicalTrials.gov, NCT03012620. FINDINGS: Between Sept 4, 2017, and Dec 29, 2020, 98 patients were enrolled, of whom 97 received treatment and were included in analyses (median age 51 years [IQR 35-65]; 53 [55%] were male; 44 [45%] were female; no data were collected on race or ethnicity). 34 (35%) patients had chordomas, 14 (14%) had alveolar soft part sarcomas, 12 (12%) had SMARCA4-deficient sarcomas or malignant rhabdoid tumours, eight (8%) had desmoplastic small round cell tumours, six (6%) had epithelioid sarcomas, four (4%) had dendritic cell sarcomas, three (3%) each had clear cell sarcomas, solitary fibrous tumours, and myxoid liposarcomas, and ten (10%) had other ultra-rare histotypes. As of data cutoff (April 11, 2022), median follow-up was 13·1 months (range 0·1-52·8; IQR 4·3-19·7). At week 12, objective response rate was 6·2% (95% CI 2·3-13·0), with no complete responses and six partial responses in the 97 patients. The most common grade 3-4 adverse events were anaemia (eight [8%] of 97), alanine aminotransferase and aspartate aminotransferase increase (six [6%]), and dyspnoea (five [5%]). 86 serious adverse events were reported in 37 patients. Five deaths due to adverse events were reported, none of which were determined to be related to treatment (two due to disease progression, two due to cancer, and one due to unknown cause). INTERPRETATION: Our data show the activity and manageable toxicity of pembrolizumab in some rare and ultra-rare sarcoma histotypes, and support the PD-1/PD-L1 pathway as a potential therapeutic target in selected histotypes. The completion of the basket study will provide further evidence regarding the activity and toxicity of pembrolizumab in identified rare types of cancer.

BACKGROUND & AIMS: Sarcopenia has long been associated with higher toxicity induced by anti-cancer treatments and shorter survival in patients with solid tumors. The creatinine-to-cystatin ratio (CC ratio, serum creatinine/cystatin C × 100) and the sarcopenia index (SI, serum creatinine × cystatin C (CysC)-based glomerular filtration rate (eGFRCysC)) are have been reported to be correlated with skeletal muscle mass. The aim of this study is to assess primarily whether the CC ratio and the SI could predict mortality in metastatic non-small cell lung cancer (NSCLC) patients treated with PD-1 inhibitors, and secondarily their impact on severe immune-related adverse effects (irAEs). METHODS: From the prospective CERTIM cohort, we analyzed retrospectively stage IV NSCLC patients, who received PD-1 inhibitors between June 2015 and November 2020 in Cochin Hospital (Paris, France). We assessed sarcopenia measuring skeletal muscle area (SMA) by computed tomography and handgrip strength (HGS) by a hand dynamometer. RESULTS: In total, 200 patients were analyzed. The CC ratio and the IS were significantly correlated with SMA and HGS: rCC/SMA = 0.360, rSI/SMA = 0.407, rCC/HGS = 0.331, rSI/HGS = 0.370. In multivariate analysis of overall survival, a lower CC ratio (HR 1.73, P = 0.033) and a lower SI (HR 1.89, P = 0.019) were independent predictors of poor prognosis. In univariate analysis of severe irAEs, CC ratio (OR 1.01, P = 0.628) and SI (OR 0.99, P = 0.595) were not associated with a higher risk of severe irAEs. CONCLUSIONS: In metastatic NSCLC patients treated with PD-1 inhibitors, a lower CC ratio and a lower SI are independent predictors of mortality. However, they are not associated with severe irAEs.

This study will address the prevalence of pre-therapeutic sarcopenia (PS) and its clinical impact during cancer treatment among adult cancer patients ≥ 18 years of age. A meta-analysis (MA) with random-effect models was performed via a MEDLINE systematic review, according to the PRISMA statement, focusing on articles published before February 2022 that reported observational studies and clinical trials on the prevalence of PS and the following outcomes: overall survival (OS), progression-free survival (PFS), post-operative complications (POC), toxicities (TOX), and nosocomial infections (NI). A total of 65,936 patients (mean age: 45.7-85 y) with various cancer sites and extensions and various treatment modes were included. Mainly defined by CT scan-based loss of muscle mass only, the pooled prevalence of PS was 38.0%. The pooled relative risks were 1.97, 1.76, 2.70, 1.47, and 1.76 for OS, PFS, POC, TOX, and NI, respectively (moderate-to-high heterogeneity, I2: 58-85%). Consensus-based algorithm definitions of sarcopenia, integrating low muscle mass and low levels of muscular strength and/or physical performance, lowered the prevalence (22%) and heterogeneity (I2 < 50%). They also increased the predictive values with RRs ranging from 2.31 (OS) to 3.52 (POC). PS among cancer patients is prevalent and strongly associated with poor outcomes during cancer treatment, especially when considering a consensus-based algorithm approach.

PURPOSE: Pemetrexed has shown efficacy as monotherapy or in combination with platinum salts in the treatment of non-small cell lung cancer and mesothelioma. However, severe hematological toxicities induced by pemetrexed-based chemotherapy have been observed. Some studies have suggested that drug interactions may be associated with pemetrexed toxicity. The objective of this study was to determine predictive factors, including drug interactions, associated with pemetrexed toxicity. METHODS: This retrospective open monocentric study included patients consecutively treated with pemetrexed after a multidisciplinary risk assessment. Patients who experienced toxicity of grade 3 or 4 according to the Common Terminology Criteria for Adverse Events v5.0, or a grade 2 leading to a change in management, during the first four courses of pemetrexed, were assigned to the early limiting toxicities (ELT) group. Univariate and multivariable logistic regression models were used to test the association variables with the occurrence of ELT. RESULTS: Seventy-four patients were included in this study (median age: 67 years, with non-small cell lung cancer adenocarcinoma (88%), mesothelioma (7%), or others (5%). Thirty-six patients (49%) were assigned to the ELT group (27 grades 3 and 4; 9 grade 2 with management modification). Three baseline factors were associated with pemetrexed ELT in univariate and multivariate analysis: cystatin clearance (p = 0.0135), albumin level (p = 0.0333), and proton pump inhibitors use (p = 0.035). CONCLUSION: To conclude, ELT induced by pemetrexed-based treatments occur frequently in cancer patients in a real-world setting. A pretherapeutic assessment before pemetrexed initiation should include three major checkpoints: use of proton pump inhibitors, sarcopenia, and denutrition evaluation.

BACKGROUND: The initial management of patients with sarcoma is a critical issue. We used the nationwide French National Cancer Institute-funded prospective sarcoma database NETSARC to report the management and oncologic outcomes in adolescents and young adults (AYAs) patients with sarcoma at the national level. PATIENTS AND METHODS: NETSARC database gathers regularly monitored and updated data from patients with sarcoma. NETSARC was queried for patients (15-30 years) with sarcoma diagnosed from 2010 to 2017 for whom tumor resection had been performed. We reported management, locoregional recurrence-free survival (LRFS), progression-free survival (PFS), and overall survival (OS) in AYA treated in French reference sarcoma centers (RSC) and outside RSC (non-RSC) and conducted multivariable survival analyses adjusted for classical prognostic factors. RESULTS: Among 3,227 patients aged 15-30 years with sarcoma diagnosed between 2010 and 2017, the study included 2,227 patients with surgery data available, among whom 1,290 AYAs had been operated in RSC, and 937 AYAs in non-RSC. Significant differences in compliance to guidelines were observed including pre-treatment biopsy (RSC: 85.9%; non-RSC 48.1%), pre-treatment imaging (RSC: 86.8%; non-RSC: 56.5%) and R0 margins (RSC 57.6%; non-RSC: 20.2%) (p < 0.001). 3y-OS rates were 81.1% (95%CI 78.3-83.6) in AYA in RSC and 82.7% (95%CI 79.4-85.5) in AYA in non-RSC, respectively. Whereas no significant differences in OS was observed in AYAs treated in RSC and in non-RSC, LRFS and PFS were improved in AYAs treated in RSC compared to AYAs treated in non-RSC (Hazard Ratios (HR): 0.58 and 0.83, respectively). CONCLUSIONS: This study highlights the importance for AYA patients with sarcoma to be managed in national sarcoma reference centers involving multidisciplinary medical teams with paediatric and adult oncologists.

This review provides an overview of histopathology, clinical presentation, molecular pathways, and potential new systemic treatments of high-grade chondrosarcomas (CS), including grade 2−3 conventional, dedifferentiated, and mesenchymal CS. The diagnosis of CS combines radiological and histological data in conjunction with patient clinical presentations. Conventional CS is the most frequent subtype of CS (85%) and represents about 25% of primary bone tumors in adults; they can be categorized according to their bone location into central, peripheral, and periosteal chondrosarcomas. Central and peripheral CS differ at the molecular level with either IDH1/2 mutations or EXT1/2 mutations, respectively. CDKN2A/B deletions are also frequent in conventional CS, as well as COL2A1 mutations. Dedifferentiated CS develops when low-grade conventional CS transforms into a high-grade sarcoma and most frequently exhibits features of osteosarcoma, fibrosarcoma, or undifferentiated pleomorphic sarcoma. Their molecular characteristics are similar to conventional CS. Mesenchymal CS is a totally different pathological entity exhibiting recurrent translocations. Their clinical presentation and management are different too. The standard treatment of CSs is wide en-bloc resection. CS are relatively radiotherapy resistant; therefore, doses >60 Gy are needed in an attempt to achieve local control in unresectable tumors. Chemotherapy is possibly effective in mesenchymal chondrosarcoma and is of uncertain value in dedifferentiated chondrosarcoma. Due to resistance to standard anticancer agents, the prognosis is poor in patients with metastatic or unresectable chondrosarcomas. Recently, the refined characterization of the molecular profile, as well as the development of new treatments, allow new therapeutic options for these rare tumors. The efficiency of IDH1 inhibitors in other malignancies suggests that these inhibitors will be part of IDH1/2 mutated conventional CS management soon. Other treatment approaches, such as PIK3-AKT-mTOR inhibitors, cell cycle inhibitors, and epigenetic or immune modulators based on improving our understanding of CS molecular biology, are emerging.

PURPOSE: The intended clinical value of frailty screening is to identify unfit patients needing geriatric assessment (GA) and to prevent unnecessary GA in fit patients. These hypotheses rely on the sensitivity and specificity of screening tests, but they have not been verified. METHODS: We performed a cross-sectional analysis of outpatients age ≥ 70 years with prostate, breast, colorectal, or lung cancer included in the ELCAPA cohort study (ClinicalTrials.gov identifier: NCT02884375) between February 2007 and December 2019. The diagnostic accuracy of the G8 Geriatric Screening Tool (G8) and modified G8 scores for identifying unfit patients was determined on the basis of GA results. We used decision curve analysis to calculate the benefit of frailty screening for detecting unfit patients and avoiding unnecessary GA in fit patients across different threshold probabilities. RESULTS: We included 1,648 patients (median age, 81 years), and 1,428 (87%) were unfit. The sensitivity and specificity were, respectively, 85% (95% CI, 84 to 87) and 59% (95% CI, 57 to 61) for G8, and 86% (95% CI, 84 to 87) and 60% (95% CI, 58 to 63) for the modified G8 score. For decision curve analysis, the net benefit (NB) for identifying unfit patients were 0.72 for G8, 0.72 for the modified G8, and 0.82 for GA at a threshold probability of 0.25. At a threshold probability of 0.33, the NBs were 0.71, 0.72, and 0.80, respectively. At a threshold probability of 0.5, the NBs were 0.68, 0.69, and 0.73, respectively. No screening tool reduced unnecessary GA in fit patients at predefined threshold probabilities. CONCLUSION: Although frailty screening tests showed good diagnostic accuracy, screening showed no clinical benefits over the GA-for-all strategy. NB approaches, in addition to diagnostic accuracy, are necessary to assess the clinical value of tests.

OBJECTIVES: Synovial sarcomas (SS) of the extremities are rare soft tissue sarcomas that are more common in young adults. We deciphered the imaging phenotype of SS with the aim to determine if imaging could provide an incremental value to currently known prognostic factors (PF)-age and histological grade-to predict long-term overall survival (OS). METHODS: This retrospective multicenter study included consecutive pediatric and adult patients with synovial sarcomas of the extremities from December 2002 to August 2020. Inclusion criteria were (i) a follow-up greater than 5 years and (ii) available pre-therapeutic MRI. A subset analysis included MRI and CT-scan. Clinical, pathological, and imaging variables were collected in all patients. The primary endpoint was to evaluate the association of these variables with OS using univariate and multivariate Cox regressions. RESULTS: Out of 428 patients screened for eligibility, 98 patients (mean age: 37.1 ± 15.2 years) were included (MRI: n = 98/98, CT scan: n = 34/98; 35%). The median OS was 75.25 months (IQR = 55.50-109.12) and thirty-six patients (n = 36/98;37%) died during follow-up. The recurrence rate was 12.2% (n =12/98). SS lesions were mostly grade 2 (57/98; 58%). On MRI, SS had a mean long-axis diameter of 67.5 ± 38.3 mm. On CT scan, 44% (15/34) were calcified. Grade (hazard ratio [HR] = 2.71; 95%CI = 1.30-5.66; p = 0.008), size of the lesions evaluated on MRI (HR = 1.02; 95% CI = 1.01-1.03; p < 0.001), and calcifications on CT scan (HR = 0.10; 95% CI = 0.02-0.50; p = 0.005) were independent PF of OS. CONCLUSIONS: This study demonstrated that imaging biomarkers can be used to predict long-term outcome in patients with SS. Strikingly, the presence of calcifications on CT scan is associated with favorable outcome and provides an incremental value over existing PF such as age, grade, and size. KEY POINTS: ⢠Beyond its diagnostic value, MRI is a pre-operative prognostic tool in synovial sarcomas of the extremities since the size of the lesion is an important prognostic factor. ⢠Calcifications on CT scans are independently and significantly associated with prolonged overall survival.

BACKGROUND: CIC-rearranged sarcomas (CIC-RS) represent the most frequent subset of "Ewing-like" undifferentiated small round cell sarcomas. These tumors tend to be more aggressive than Ewing sarcomas. Moreover, treatment strategy can differ according to teams. The primary aim of this retrospective study was to describe the characteristics, treatments, and outcome for patients with CIC-RS included in the French NETSARC+ database. METHODS: Pediatric and adult patients from 13 French centers with a diagnosis of CIC-RS were registered from October 2008 to March 2021. Patients and tumors characteristics were collected from the national network NETSARC+ database (http://netsarc.sarcomabcb.org). CIC-RS diagnosis was pathologically and molecularly confirmed with a central review by expert pathologists. Two groups of patients were studied: those treated as classical Ewing sarcomas (cohort EwS) and those treated as high-grade soft tissue sarcomas (cohort STS) according to ESMO and/or EpSSG guidelines. Survival was calculated using the Kaplan-Meier method and the log-rank test was used to compare survival. RESULTS: Among 79 patients, the male/female sex ratio was 0.7 and the median age at diagnosis was 27 years (range 2-87). With a median follow-up of 37 months, 39 patients died of the disease. Median overall survival from diagnosis was 18 months, with no significant difference between both cohorts (p = 0.9). Nevertheless, when focusing on patients with metastatic disease at diagnosis (N = 21), all patients from cohort STS died of disease while some patients from cohort EwS were still alive and in complete remission. CONCLUSION: FSG experience confirms the aggressive clinical course of CDS patients regardless of chemotherapy regimen.

BACKGROUND: Metastatic leiomyosarcomas have a poor prognosis, and currently doxorubicin alone is used as the standard first-line treatment. Doxorubicin combined with trabectedin has shown promising results in phase 1 and 2 studies. We aimed to identify and compare the progression-free survival of patients with metastatic or unresectable uterine or soft tissue leiomyosarcoma treated with doxorubicin and trabectedin combined as first-line therapy versus doxorubicin alone in a phase 3 trial. METHODS: LMS-04 was a randomised, multicentre, open-label, superiority phase 3 trial, which included patients from 20 centres of the French Sarcoma Group (anticancer centers or hospitals with an oncological unit) in France. Eligible patients were aged 18 years or older, had an Eastern Cooperative Oncology Group performance status of 0-1, and had metastatic or relapsed unresectable leiomyosarcomas that had not previously been treated with chemotherapy. Patients were randomly assigned (1:1), by means of an interactive web response system (permuted blocks of different sizes from two to six), to receive either intravenous doxorubicin alone (75 mg/m2) once every 3 weeks for up to six cycles or of intravenous doxorubicin (60 mg/m2) plus intravenous trabectedin (1·1 mg/m2) once every 3 weeks up to six cycles followed by maintenance with trabectedin alone. Surgery for residual disease was allowed in both groups after six cycles of treatment. Randomisation was stratified by tumour location (uterine vs soft tissue) and disease (locally advanced vs metastatic). The primary endpoint was progression-free survival assessed by blinded independent central review and according to Response Evaluation Criteria in Solid Tumours 1.1 criteria. Efficacy analyses were performed on all randomly assigned patients, based on the intention-to-treat principle. The safety population included all randomly assigned patients who received at least one cycle of treatment. This trial is registered with ClinicalTrials.gov, NCT02997358, and is closed to enrolment. FINDINGS: Between Jan 18, 2017, and March 21, 2019, 150 patients were enrolled (67 with uterine leiomyosarcomas and 83 with soft tissue leiomyosarcomas) and included in the intention-to-treat population: 76 in the doxorubicin alone group and 74 in the doxorubicin plus trabectedin group. The median duration of follow-up was 36·9 months (IQR 30·0-43·2) in the doxorubicine group and 38·8 months (32·7-44·2) in the doxorubicin plus trabectedin group. Median progression-free survival was significantly longer with doxorubicin plus trabectedin versus doxorubicin alone (12·2 months [95% CI 10·1-15·6] vs 6·2 months [4·1-7·1]; adjusted hazard ratio 0·41 [95% CI 0·29-0·58]; p<0·0001). The most common grade 3-4 adverse events were neutropenia (ten [13%] of 75 patients in the doxorubicin alone group vs 59 [80%] in the doxorubicin plus trabectedin group), anaemia (four [5%] vs 23 [31%]), thrombocytopenia (0 vs 35 [47%]), and febrile neutropenia (seven [9%] vs 21 [28%]). Nine (12%) patients in the doxorubicin alone group and 15 (201%) patients in the doxorubicin plus trabectedin group has serious adverse events. There was only one treatment-related death, reported in the doxorubicin alone group (cardiac failure). INTERPRETATION: Doxorubicin plus trabectedin in first-line therapy was found to significantly increase progression-free survival in patients with metastatic or unresectable leiomyosarcomas compared with doxorubicin alone, despite a higher but manageable toxicity, and could be considered an option for the first-line treatment of metastatic leiomyosarcomas.
