RESUMEN
PURPOSE: The randomized, open-label, global phase III TROPION-Lung01 study compared the efficacy and safety of datopotamab deruxtecan (Dato-DXd) versus docetaxel in patients with pretreated advanced/metastatic non-small cell lung cancer (NSCLC). METHODS: Patients received Dato-DXd 6 mg/kg or docetaxel 75 mg/m2 once every 3 weeks. Dual primary end points were progression-free survival (PFS) and overall survival (OS). Objective response rate, duration of response, and safety were secondary end points. RESULTS: In total, 299 and 305 patients were randomly assigned to receive Dato-DXd or docetaxel, respectively. The median PFS was 4.4 months (95% CI, 4.2 to 5.6) with Dato-DXd and 3.7 months (95% CI, 2.9 to 4.2) with docetaxel (hazard ratio [HR], 0.75 [95% CI, 0.62 to 0.91]; P = .004). The median OS was 12.9 months (95% CI, 11.0 to 13.9) and 11.8 months (95% CI, 10.1 to 12.8), respectively (HR, 0.94 [95% CI, 0.78 to 1.14]; P = .530). In the prespecified nonsquamous histology subgroup, the median PFS was 5.5 versus 3.6 months (HR, 0.63 [95% CI, 0.51 to 0.79]) and the median OS was 14.6 versus 12.3 months (HR, 0.84 [95% CI, 0.68 to 1.05]). In the squamous histology subgroup, the median PFS was 2.8 versus 3.9 months (HR, 1.41 [95% CI, 0.95 to 2.08]) and the median OS was 7.6 versus 9.4 months (HR, 1.32 [95% CI, 0.91 to 1.92]). Grade ≥3 treatment-related adverse events occurred in 25.6% and 42.1% of patients, and any-grade adjudicated drug-related interstitial lung disease/pneumonitis occurred in 8.8% and 4.1% of patients, in the Dato-DXd and docetaxel groups, respectively. CONCLUSION: Dato-DXd significantly improved PFS versus docetaxel in patients with advanced/metastatic NSCLC, driven by patients with nonsquamous histology. OS showed a numerical benefit but did not reach statistical significance. No unexpected safety signals were observed.
RESUMEN
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are the standard of care for the management of EGFR-mutated non-small cell lung cancer. Recent results from the HARMONi-A trial lead to considering ivonescimab-a first-in-class, bispecific antibody targeting PD-1 and VEGF-plus chemotherapy as a new second-line option following third-generation TKIs.

The combination of chemotherapy and targeted therapy has been validated in non-small-cell lung cancer (NSCLC) patients with EGFR mutations. We therefore investigated whether this type of combined approach could be more widely used by targeting other genetic alterations present in NSCLC. PDXs were generated from patients with NSCLC adenocarcinomas (ADCs) and squamous-cell carcinomas (SCCs). Targeted NGS analyses identified various molecular abnormalities in the MAPK and PI3K pathways and in the cell cycle process in our PDX panel. The antitumor efficacy of targeted therapies alone or in combination with chemotherapy was then tested in vivo. We observed that trametinib, BKM120, AZD2014 and palbociclib increased the efficacy of each chemotherapy in SCC PDXs, in contrast to a non-insignificant or slight improvement in ADCs. Furthermore, we observed high efficacy of trametinib in KRAS-, HRAS- and NRAS-mutated tumors (ADCs and SCCs), suggesting that the MEK inhibitor may be useful in a wider population of NSCLC patients, not just those with KRAS-mutated ADCs. Our results suggest that the detection of pathogenic variants by NGS should be performed in all NSCLCs, and particularly in SCCs, to offer patients a more effective combination of chemotherapy and targeted therapy.
RESUMEN
OBJECTIVES: This paper aims to identify and address gaps in cancer treatment and diagnosis within European health services, focusing specifically on discrepancies between clinical guidelines and policy guidelines. It seeks to highlight how the underutilization of advanced diagnostic techniques recommended by medical societies contributes to missed opportunities for improving patient outcomes. METHODS: A comprehensive analysis was conducted across multiple European countries to assess the compliance and integration of clinical guidelines with the availability of advanced diagnostic technologies. Secondary data related to clinical and policy guidelines in cancer care were collected and analyzed. Key indicators of adoption and utilization of next-generation sequencing and liquid biopsy were examined to evaluate their impact on health service efficiency and patient care. RESULTS: The analysis revealed significant discrepancies between the recommendations of medical societies regarding advanced diagnostic techniques and their adoption in health policy decisions across Europe. Country-specific assessments indicated varying levels of alignment between clinical guidelines and the availability of advanced diagnostics. These findings underscored missed opportunities for optimizing patient care and health service efficiency through better alignment and integration of clinical guidelines with policy decisions. CONCLUSIONS: This study concludes that there is a critical need for health policy decision-makers to prioritize the adoption of clinical guidelines in resource allocation and health service organization. Greater attention to the recommendations of medical societies regarding advanced diagnostic techniques could significantly enhance diagnostic accuracy, treatment efficacy, and overall patient outcomes in cancer care. The paper advocates for policy reforms that acknowledge and leverage the potential benefits of advanced diagnostics in improving health service performance and patient-centered care across Europe.
RESUMEN
Over the past 20 years, several innovative therapies have been implemented in the treatment of lung cancer that have had reported survival benefits in clinical trials. Whether these improvements translate into the clinic setting has not been studied yet. We retrospectively analyzed all patients consecutively treated at Institute Curie for metastatic lung cancer. Diagnosis date was used to define three periods, based on the approvals of novel treatment strategies in the first-line setting, including targeted therapies in 2010 and immunotherapy in 2018. Endpoints included Overall survival (OS), survival rate of 2 years and 5 years, and a conditional survival rate of 2 years (if still alive at 6 months from treatment initiation). A total of 673 patients were identified for Period 1-2000 to 2009, 752 for Period 2-2010 to 2017, and 768 for Period 3-2018 to 2020. Median OS in the whole cohort was 11.1, 15.5, and 16.2 months, respectively. Median OS for patients with NSCLC or SCLC was 11.2, 17.2, and 18.2 months, or 10.9, 11.7, and 11.2 months, respectively. The two-year conditional survival was more favorable for NSCLC than SCLC patients. Outcomes were statistically higher for women as compared to men in all periods and all subgroups. Survival of patients with metastatic lung cancer has improved over the past 20 years, mostly in NSCLC, along with the implementation of novel treatment strategies.
RESUMEN
INTRODUCTION: In the AEGEAN trial, neoadjuvant durvalumab plus platinum-based chemotherapy (D+CT) followed by adjuvant durvalumab, versus neoadjuvant chemotherapy alone, significantly improved pathological complete response (pCR) rate and event-free survival (EFS) in patients with resectable NSCLC. In the PACIFIC trial, consolidation durvalumab significantly improved progression-free (PFS) and overall survival (OS) for patients with unresectable stage III NSCLC after chemoradiotherapy. Strong pathological and clinical outcomes with chemoimmunotherapy have generated interest in its use to enable patients with borderline-resectable NSCLC to undergo surgery. Additionally, for patients initially deemed resectable but who later become unresectable/inoperable during neoadjuvant treatment, consolidation immunotherapy after chemoradiotherapy should be explored. PATIENTS AND METHODS: MDT-BRIDGE (NCT05925530) is a multicenter, phase II, non-randomized study in â¼140 patients with EGFR/ALK wild-type, stage IIB-IIIB (N2) NSCLC. Following baseline multidisciplinary team (MDT) assessment to determine resectable/borderline-resectable status, all patients receive 2 cycles of neoadjuvant D+CT every 3 weeks, followed by MDT reassessment of resectability. Patients deemed resectable receive 1-2 additional cycles of D+CT followed by surgery (Cohort 1). Patients deemed unresectable receive standard-of-care chemoradiotherapy (Cohort 2). Cohort 1 patients who become ineligible for surgery can enter Cohort 2. Following surgery or chemoradiotherapy, patients receive adjuvant or consolidation durvalumab for 1 year. The primary endpoint is resection rate in all patients. Additional endpoints include resection rates by baseline resectable/borderline-resectable status, resection outcomes, EFS/PFS, OS, pCR rate, circulating tumor DNA dynamics pre- and post-surgery (including correlation with clinical outcomes), and safety. CONCLUSION: Enrollment began in February 2024; primary completion is anticipated in April 2026.

INTRODUCTION: In France, 40% of patients diagnosed with lung cancer are ≥70 years old, but these are under-represented in clinical trials. Using data from the French Epidemiological Strategy and Medical Economics (ESME) platform on Lung Cancer (LC), the objective is to provide an overview of the management and the prognosis of older patients with advanced or metastatic non-small cell lung cancer (AM-NSCLC) in a real-world context. MATERIALS AND METHODS: From the ESME-LC database, we selected patients with AM-NSCLC (stage IIIB, IIIC, and IV), diagnosed between 2015 and 2019, and who received first-line systemic treatment. Demographics, tumour characteristics, and treatment received were described in patients ≥70, and compared to younger ones. Real-world progression-free survival (rwPFS) and overall survival (OS) were evaluated using the multivariable Cox model. RESULTS: Among 10,002 patients with AM-NSCLC, the median age was 64 years, with 2,754 (27.5%) aged ≥70. In comparison with patients <70, older patients were more often male, with worse performance status and more comorbidities, but they were less underweight and more often non-smokers. The proportion of EGFR mutated non-squamous NSCLC was higher in older patients (25.0% vs 12.8%, p < 0.001), particularly among smokers and former smokers (12.7% vs 7.3%, p < 0.001). Among patients ≥70, 76.6% received first-line chemotherapy (including 67.0% treated with a platinum-based doublet), 15.0% received only targeted therapy, and 11.0% received immunotherapy (alone or in combination). Median first-line rwPFS was 5.1 months (95% confidence interval [CI] = [4.8;5.4]) for patients ≥70 and 4.6 months (95%CI = [4.4;4.8]) for patients <70, but age was not associated with rwPFS in multivariable analysis. Median OS was 14.8 months (95%CI = [13.9;16.1]) for patients ≥70 and 16.7 months (95%CI = [15.9;17.5]) for patients <70, with a significant effect of age in multivariable analysis for patients treated with chemotherapy and/or with targeted therapy, but not for patients treated with immunotherapy (alone or in combination with chemotherapy). DISCUSSION: In this real-world cohort of patients with AM-NSCLC, age was not associated with first-line rwPFS regardless of treatment received, nor with OS for patients receiving immunotherapy. However, OS was significantly shorter for patients aged ≥70 treated with chemotherapy or with targeted therapy alone.

What is this summary about? This is a plain language summary of an article that describes the first results of the phase 3 PAPILLON study in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) with Exon 20 insertion (Ex20ins) mutations in the epidermal growth factor receptor (EGFR) gene who had not had any cancer treatment before. Researchers looked at how safe and effective the bispecific antibody amivantamab (brand name: RYBREVANT®) plus chemotherapy was in comparison to chemotherapy alone.Amivantamab was approved by the US Food and Drug Administration (FDA) in May 2021 for patients with the same type of cancer who got worse after chemotherapy. In March 2024, amivantamab was approved in combination with chemotherapy for previously untreated patients with the same type of cancer. The National Comprehensive Cancer Network® (NCCN®) recommends amivantamab plus chemotherapy as a preferred first treatment option for these patients.What were the results? 308 patients were randomly selected to receive amivantamab plus chemotherapy or chemotherapy alone. Patients who received amivantamab plus chemotherapy lived longer without having their disease get worse compared to those who had chemotherapy. Patients who had amivantamab plus chemotherapy also had the risk of their disease getting worse or dying reduced by 60% compared to chemotherapy. After 18 months of treatment, 31% of patients on amivantamab plus chemotherapy did not have their cancer grow or spread compared to 3% with chemotherapy. More than 7 in 10 patients who had amivantamab plus chemotherapy had tumors that shrank by at least 30% or were no longer detectable. This only happened in less than 5 in 10 patients who had chemotherapy alone.All patients had side effects, with the most common being neutropenia (occurring in 59% of patients), paronychia (56%), and rash/red skin bumps (54%/31%) for those treated with amivantamab plus chemotherapy, and anemia (55%), neutropenia (45%), and nausea (42%) for those treated with chemotherapy. Few patients (7%) stopped taking amivantamab due to side effects.What do the results mean? Amivantamab plus chemotherapy worked well to extend the time that patients' cancer did not worsen. Patients had a 60% lower risk of death or having their cancer worsen compared to those who had chemotherapy. These benefits were seen in groups of patients with different characteristics.Amivantamab plus chemotherapy works well, is well tolerated, and is a good treatment option for untreated patients who have advanced NSCLC with EGFR Ex20ins mutations.
RESUMEN
BACKGROUND: Sotorasib 960 mg once daily is approved to treat KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC). Sotorasib exhibits non-dose proportional pharmacokinetics and clinical responses at lower doses; therefore, we evaluated the efficacy and safety of sotorasib 960 mg and 240 mg. METHODS: In this phase 2, randomized, open-label study, adults with KRAS G12C-mutated advanced NSCLC received sotorasib 960 mg or 240 mg once daily. Primary endpoints were objective response rate (ORR) and safety. Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and pharmacokinetics. The study was not powered for formal statistical hypothesis testing. RESULTS: In the 960 mg group (n = 104), ORR was 32.7 % and DCR was 86.5 %. In the 240 mg group (n = 105), ORR was 24.8 % and DCR was 81.9 %. Median PFS was 5.4 months (960 mg) and 5.6 months (240 mg). At a median follow-up of 17.5 months, median OS was 13.0 months (960 mg) and 11.7 months (240 mg). AUC0-24 h and Cmax were 1.3-fold numerically higher with the 960 mg dose. Treatment-emergent adverse events (TEAEs, ≥10 %) for 960 mg and 240 mg doses, respectively, were diarrhea (39.4 %; 31.7 %), nausea (23.1 %; 19.2 %), increased alanine aminotransaminase (14.4 %; 17.3 %), and increased aspartate aminotransferase (13.5 %; 13.5 %). CONCLUSIONS: Patients treated with sotorasib 960 mg once daily had numerically higher ORR and DCR, and longer DOR and OS, than patients treated with 240 mg in this descriptive analysis. TEAEs were manageable with label-directed dose modifications. CLINICAL TRIAL REGISTRATION: NCT03600883.

BACKGROUND: Amivantamab, an EGFR-MET bispecific antibody, is the first approved targeted therapy for patients with EGFR Ex20ins NSCLC after prior platinum-based chemotherapy-a population with historically poor outcomes before amivantamab approval. As antitumor activity in single-arm studies typically focuses on responders, the evaluation of outcomes in patients with stable disease (SD) as best response is of clinical interest. PATIENTS AND METHODS: Among 114 patients with post-platinum EGFR Ex20ins NSCLC in CHRYSALIS (NCT02609776; data cutoff: March 30, 2021), response was assessed by blinded independent central review via RECIST v1.1. Patients alive and receiving therapy at 12 weeks were grouped by response at this landmark: partial or complete response (PR+), SD, or progressive disease (PD). Progression-free survival (PFS) and overall survival (OS) by response cohort were determined using the Kaplan-Meier method; hazard ratios (HRs) and 95% confidence intervals (CIs) between response cohorts were calculated using Cox proportional hazards regression. RESULTS: Among patients alive and receiving therapy at 12 weeks (n=107), 42 (39%) had PR+, 52 (49%) had SD, and 13 (12%) had PD. Among patients with PR+ and SD, median PFS was 12.2 and 7.0 months, respectively. A corresponding improvement in OS was observed in patients achieving PR+ (median: not reached; HR vs PD=0.21 [95% CI: 0.08-0.54]) and SD (median: 23.0 months; HR vs PD=0.33 [95% CI: 0.14-0.77]), relative to those with PD (median: 14.0 months). CONCLUSION: SD was observed in 49% of patients receiving amivantamab, with corresponding increases in OS that dramatically improved the prognoses of this patient population.

BACKGROUND: This study aimed to estimate the relative efficacy of neoadjuvant nivolumab in combination with chemotherapy (neoNIVO + CT) compared to relevant treatments amongst resectable non-metastatic non-small-cell lung cancer (rNSCLC) patients. METHODS: Treatment comparisons were based on a network meta-analysis (NMA) using randomized clinical trial data identified via systematic literature review (SLR). The outcomes of interest were event-free survival (EFS) and pathological complete response (pCR). NeoNIVO + CT was compared to neoadjuvant chemotherapy (neoCT), neoadjuvant chemoradiotherapy (neoCRT), adjuvant chemotherapy (adjCT), and surgery alone (S). Due to the potential for effect modification by stage, all-stage and stage-specific networks were considered. Fixed-effect (FE) and random-effects Bayesian NMA models were run (EFS = hazard ratios [HR]; pCR = odds ratios [OR]; 95% credible intervals [CrI]). RESULTS: Sixty-one RCTs were identified (base case = 9 RCTs [n = 1978 patients]). In the all-stages FE model, neoNIVO + CT had statistically significant EFS improvements relative to neoCT (HR = 0.68 [95% CrI: 0.49, 0.94]), S (0.59 [0.42, 0.82]), adjCT (0.66 [0.45, 0.96]), but not relative to neoCRT (HR = 0.77 [0.52, 1.16]). NeoNIVO + CT (5 RCTs) had statistically significant higher odds of pCR relative to neoCT (OR = 12.53 [5.60, 33.82]) and neoCRT (7.15 [2.31, 24.34]). Stage-specific model findings were consistent. CONCLUSIONS: This NMA signals improved EFS and/or pCR of neoNIVO + CT relative to comparators among patients with rNSCLC.
RESUMEN
A chemical library is a key element in the early stages of pharmaceutical research. Its design encompasses various factors, such as diversity, size, ease of synthesis, aimed at increasing the likelihood of success in drug discovery. This article explores the collaborative efforts of computational and synthetic chemists in tailoring chemical libraries for cost-effective and resource-efficient use, particularly in the context of academic research projects. It proposes chemoinformatics methodologies that address two pivotal questions: first, crafting a diverse panel of under 1000 compounds from an existing pool through synthetic efforts, leveraging the expertise of organic chemists; and second, expanding pharmacophoric diversity within this panel by creating a highly accessible virtual chemical library. Chemoinformatics tools were developed to analyse initial panel of about 10,000 compounds into two tailored libraries: eIMS and vIMS. The eIMS Library comprises 578 diverse in-stock compounds ready for screening. Its virtual counterpart, vIMS, features novel compounds guided by chemists, ensuring synthetic accessibility. vIMS offers a broader array of binding motifs and improved drug-like characteristics achieved through the addition of diverse functional groups to eIMS scaffolds followed by filtering of reactive or unusual structures. The uniqueness of vIMS is emphasized through a comparison with commercial suppliers' virtual chemical space.
RESUMEN
PURPOSE: Telisotuzumab vedotin (Teliso-V) is a c-Met-directed antibody-drug conjugate with a monomethyl auristatin E cytotoxic payload. The phase II LUMINOSITY trial (ClinicalTrials.gov identifier: NCT03539536) aimed to identify the optimal c-Met protein-overexpressing non-small cell lung cancer (NSCLC) population for treatment with Teliso-V (stage I) and expand the selected group for efficacy evaluation (stage II). Stage II enrolled patients with nonsquamous epidermal growth factor receptor (EGFR)-wildtype NSCLC. METHODS: Eligible patients had locally advanced/metastatic c-Met protein-overexpressing NSCLC and ≤2 previous lines of therapy (including ≤1 line of systemic chemotherapy). c-Met protein overexpression in nonsquamous EGFR-wildtype NSCLC was defined as ≥25% tumor cells with 3+ staining (high [≥50% 3+]; intermediate [≥25%-<50%]). Teliso-V was administered at 1.9 mg/kg once every 2 weeks. The primary end point was overall response rate (ORR) by independent central review. RESULTS: In total, 172 patients with nonsquamous EGFR-wildtype NSCLC received Teliso-V in stages I and II. ORR was 28.6% (95% CI, 21.7 to 36.2; c-Met high, 34.6% [95% CI, 24.2 to 46.2]; c-Met intermediate, 22.9% [95% CI, 14.4 to 33.4]). The median duration of response was 8.3 months (95% CI, 5.6 to 11.3; c-Met high, 9.0 [95% CI, 4.2 to 13.0]; c-Met intermediate: 7.2 [95% CI, 5.3 to 11.5]). The median overall survival was 14.5 months (95% CI, 9.9 to 16.6; c-Met high, 14.6 [95% CI, 9.2 to 25.6]; c-Met intermediate, 14.2 [95% CI, 9.6 to 16.6]). The median progression-free survival was 5.7 months (95% CI, 4.6 to 6.9; c-Met high, 5.5 [95% CI, 4.1 to 8.3]; c-Met intermediate: 6.0 [95% CI, 4.5 to 8.1]). Most common any-grade treatment-related adverse events (AEs) were peripheral sensory neuropathy (30%), peripheral edema (16%), and fatigue (14%); the most common grade ≥3 AE was peripheral sensory neuropathy (7%). CONCLUSION: Teliso-V was associated with durable responses in c-Met protein-overexpressing nonsquamous EGFR-wildtype NSCLC, especially in those with high c-Met. AEs were generally manageable.

PURPOSE: The open-label, phase III EVOKE-01 study evaluated sacituzumab govitecan (SG) versus standard-of-care docetaxel in metastatic non-small cell lung cancer (mNSCLC) with progression on/after platinum-based chemotherapy, anti-PD-(L)1, and targeted treatment for actionable genomic alterations (AGAs). Primary analysis is reported. METHODS: Patients were randomly assigned 1:1 (stratified by histology, best response to last anti-PD-(L)1-containing regimen, and AGA treatment received or not) to SG (one 10 mg/kg intravenous infusion on days 1 and 8) or docetaxel (one 75 mg/m2 intravenous infusion on day 1) in 21-day cycles. Primary end point was overall survival (OS). Key secondary end points were investigator-assessed progression-free survival (PFS), objective response rate, patient-reported symptom assessment, and safety. RESULTS: In the intention-to-treat population (SG, n = 299; docetaxel, n = 304), 55.4% had one previous line of therapy. Median follow-up was 12.7 months (range, 6.0-24.0). The primary end point was not met. There was a numerical OS improvement for SG versus docetaxel (median, 11.1 v 9.8 months; hazard ratio [HR], 0.84 [95% CI, 0.68 to 1.04]; one-sided P = .0534), consistent across squamous and nonsquamous histologies. Median PFS was 4.1 versus 3.9 months (HR, 0.92 [95% CI, 0.77 to 1.11]). An OS benefit was observed for SG (n = 192) versus docetaxel (n = 191) in mNSCLC nonresponsive to last anti-PD-(L)1-containing regimen (3.5-month median OS increase; HR, 0.75 [95% CI, 0.58 to 0.97]); this was consistent across histologies. Among patients receiving SG and docetaxel, 6.8% and 14.2% discontinued because of treatment-related adverse events (TRAEs), respectively; 1.4% and 1.0%, respectively, had TRAEs leading to death. CONCLUSION: Although statistical significance was not met, OS numerically improved with SG versus docetaxel, which was consistent across histologies. Clinically meaningful improvement in OS was noted in mNSCLC nonresponsive to last anti-PD-(L)1-containing regimen. SG was better tolerated than docetaxel and consistent with its known safety profile, with no new safety signals.

To investigate associations between a swimmer's career progression and winning a medal at the Olympic Games (OG) or World Championships (WC). A total of 4631 swimming performances of 1535 top swimmers (653 women, 882 men) from 105 nationalities since1973 were extracted from FINA rankings. A panel of 12 predictor variables including nationality, gender, competition, age, number and timing of competitions, pattern of progressions and regressions in performance, and medal outcomes was established. Linear logistic regression was used to study the association between winning a medal and predictor variables. Logistic regression coefficients were obtained by training on 80% of the database, and prediction accuracy evaluated on the remaining 20%. Using the training set, a selection of 9 most relevant features for prediction of winning a medal (target variable) was obtained through exhaustive feature selection and cross-validation: nationality, competition, number of competitions, number of annual career progressions (nb_prog), maximum annual career progression (max-progr), number of annual career regressions (nb_reg), age at maximum annual progression, P6 (the level of performance six months before the World Championships or Olympic Games), and P2 (the level of performance two months before the World Championships or Olympic Games). A logistic regression model was built and retrained on the entire training set achieved an area under the ROC curve of ~90% on the test set. The odds of winning a medal increased by 1.64 (95% CI, 1.39-1.91) and 1.44 (1.22-1.72) for each unit of increase in max-progr and n-prog, respectively. Odds of winning a medal decreased by 0.60 (0.49-0.72) for a unit increase in n-reg. In contrast, the odds increased by 1.70 (1.39-2.07) and 4.35 (3.48-5.42) for improvements in the 6 and 2 months before competition (P<0.001, for all variables). The likelihood of a swimmer winning an international medal is improved by ~40-90% with progressions from season-to-season, and reducing the number of regressions in performance. The chances of success are also improved 2- to 4-fold by substantial improvements in performance in the months before competition.

Explaining the decisions made by a radiomic model is of significant interest, as it can provide valuable insights into the information learned by complex models and foster trust in well-performing ones, thereby facilitating their clinical adoption. Promising radiomic approaches that aggregate information from multiple regions within an image currently lack suitable explanation tools that could identify the regions that most significantly influence their decisions. Here we present a model- and modality-agnostic tool (RadShap, https://github.com/ncaptier/radshap), based on Shapley values, that explains the predictions of multiregion radiomic models by highlighting the contribution of each individual region. Methods: The explanation tool leverages Shapley values to distribute the aggregative radiomic model's output among all the regions of interest of an image, highlighting their individual contribution. RadShap was validated using a retrospective cohort of 130 patients with advanced non-small cell lung cancer undergoing first-line immunotherapy. Their baseline PET scans were used to build 1,000 synthetic tasks to evaluate the degree of alignment between the tool's explanations and our data generation process. RadShap's potential was then illustrated through 2 real case studies by aggregating information from all segmented tumors: the prediction of the progression-free survival of the non-small cell lung cancer patients and the classification of the histologic tumor subtype. Results: RadShap demonstrated strong alignment with the ground truth, with a median frequency of 94% for consistently explained predictions in the synthetic tasks. In both real-case studies, the aggregative models yielded superior performance to the single-lesion models (average [±SD] time-dependent area under the receiver operating characteristic curve was 0.66 ± 0.02 for the aggregative survival model vs. 0.55 ± 0.04 for the primary tumor survival model). The tool's explanations provided relevant insights into the behavior of the aggregative models, highlighting that for the classification of the histologic subtype, the aggregative model used information beyond the biopsy site to correctly classify patients who were initially misclassified by a model focusing only on the biopsied tumor. Conclusion: RadShap aligned with ground truth explanations and provided valuable insights into radiomic models' behaviors. It is implemented as a user-friendly Python package with documentation and tutorials, facilitating its smooth integration into radiomic pipelines.

BACKGROUND: Amivantamab plus lazertinib (amivantamab-lazertinib) has shown clinically meaningful and durable antitumor activity in patients with previously untreated or osimertinib-pretreated EGFR (epidermal growth factor receptor)-mutated advanced non-small-cell lung cancer (NSCLC). METHODS: In a phase 3, international, randomized trial, we assigned, in a 2:2:1 ratio, patients with previously untreated EGFR-mutated (exon 19 deletion or L858R), locally advanced or metastatic NSCLC to receive amivantamab-lazertinib (in an open-label fashion), osimertinib (in a blinded fashion), or lazertinib (in a blinded fashion, to assess the contribution of treatment components). The primary end point was progression-free survival in the amivantamab-lazertinib group as compared with the osimertinib group, as assessed by blinded independent central review. RESULTS: Overall, 1074 patients underwent randomization (429 to amivantamab-lazertinib, 429 to osimertinib, and 216 to lazertinib). The median progression-free survival was significantly longer in the amivantamab-lazertinib group than in the osimertinib group (23.7 vs. 16.6 months; hazard ratio for disease progression or death, 0.70; 95% confidence interval [CI], 0.58 to 0.85; P<0.001). An objective response was observed in 86% of the patients (95% CI, 83 to 89) in the amivantamab-lazertinib group and in 85% of those (95% CI, 81 to 88) in the osimertinib group; among patients with a confirmed response (336 in the amivantamab-lazertinib group and 314 in the osimertinib group), the median response duration was 25.8 months (95% CI, 20.1 to could not be estimated) and 16.8 months (95% CI, 14.8 to 18.5), respectively. In a planned interim overall survival analysis of amivantamab-lazertinib as compared with osimertinib, the hazard ratio for death was 0.80 (95% CI, 0.61 to 1.05). Predominant adverse events were EGFR-related toxic effects. The incidence of discontinuation of all agents due to treatment-related adverse events was 10% with amivantamab-lazertinib and 3% with osimertinib. CONCLUSIONS: Amivantamab-lazertinib showed superior efficacy to osimertinib as first-line treatment in EGFR-mutated advanced NSCLC.

RESUMEN
Regulatory T cells (Tregs) are plastic cells playing a pivotal role in the maintenance of immune homeostasis. Tregs actively adapt to the microenvironment where they reside; as a consequence, their molecular and functional profiles differ among tissues and pathologies. In tumors, the features acquired by Tregs remains poorly characterized. Here, we observe that human tumor-infiltrating Tregs selectively overexpress CD74, the MHC class II invariant chain. CD74 has been previously described as a regulator of antigen-presenting cell biology, however its function in Tregs remains unknown. CD74 genetic deletion in human primary Tregs reveals that CD74KO Tregs exhibit major defects in the organization of their actin cytoskeleton and intracellular organelles. Additionally, intratumoral CD74KO Tregs show a decreased activation, a drop in Foxp3 expression, a low accumulation in the tumor, and consistently, they are associated with accelerated tumor rejection in preclinical models in female mice. These observations are unique to tumor conditions as, at steady state, CD74KO-Treg phenotype, survival, and suppressive capacity are unaffected in vitro and in vivo. CD74 therefore emerges as a specific regulator of tumor-infiltrating Tregs and as a target to interfere with Treg anti-tumor activity.

There is a compelling need for approaches to predict the efficacy of immunotherapy drugs. Tumor-on-chip technology exploits microfluidics to generate 3D cell co-cultures embedded in hydrogels that recapitulate simplified tumor ecosystems. Here, we present the development and validation of lung tumor-on-chip platforms to quickly and precisely measure ex vivo the effects of immune checkpoint inhibitors on T cell-mediated cancer cell death by exploiting the power of live imaging and advanced image analysis algorithms. The integration of autologous immunosuppressive FAP+ cancer-associated fibroblasts impaired the response to anti-PD-1, indicating that tumors-on-chips are capable of recapitulating stroma-dependent mechanisms of immunotherapy resistance. For a small cohort of non-small cell lung cancer patients, we generated personalized tumors-on-chips with their autologous primary cells isolated from fresh tumor samples, and we measured the responses to anti-PD-1 treatment. These results support the power of tumor-on-chip technology in immuno-oncology research and open a path to future clinical validations.

INTRODUCTION: Thymomas are rare intrathoracic malignancies that can relapse after surgery. Whether or not Post-Operative RadioTherapy (PORT) should be delivered after surgery remains a major issue. RADIORYTHMIC is an ongoing, multicenter, randomized phase 3 trial addressing this question in patients with completely R0 resected Masaoka-Koga stage IIb/III thymoma. Experts in the field met to develop recommendations for PORT. METHODS: A scientific committee from the RYTHMIC network identified key issues regarding the modalities of PORT in completely resected thymoma. A DELPHI method was used to question 24 national experts, with 115 questions regarding the following: (1) imaging techniques, (2) clinical target volume (CTV) and margins, (3) dose constraints to organs at risk, (4) dose and fractionation, and (5) follow-up and records. Consensus was defined when opinions reached more than or equal to 80% agreement. RESULTS: We established the following recommendations: preoperative contrast-enhanced computed tomography (CT) scan is recommended (94% agreement); optimization of radiation delivery includes either a four-dimensional CT-based planning (82% agreement), a breath-holding inspiration breath-hold-based planning, or daily control CT imaging (81% agreement); imaging fusion based on cardiovascular structures of preoperative and planning CT scan is recommended (82% agreement); right coronary and left anterior descending coronary arteries should be delineated as cardiac substructures (88% agreement); rotational RCMI/volumetric modulated arc therapy is recommended (88% agreement); total dose is 50 Gy (81% agreement) with 1.8 to 2 Gy per fraction (94% agreement); cardiac evaluation and follow-up for patients with history of cardiovascular disease are recommended (88% agreement) with electrocardiogram and evaluation of left ventricular ejection fraction at 5 years and 10 years. CONCLUSION: This is the first consensus for PORT in thymoma. Implementation will help to harmonize practices.
