RESUMO
Background: We evaluated outcomes in non-small cell lung cancer (NSCLC) patients who presented with brain-only metastatic (BOM) disease overall and by EGFR/ALK mutation status. Methods: We analyzed clinico-demographic, treatment and survival data for all NSCLC patients who presented to our center between 2014 and 2016 with BOM as their first presentation of metastatic disease. Differences in overall survival (OS) were evaluated using log-rank tests for NSCLC wildtype (NSCLCwt) versus NSCLC with an ALK-rearrangement/EGFR-mutation (NSCLCmut+). Results: Of 109 patients with BOM, median age was 68 years; 51 % were female; 69 % Caucasian; 76 % ever-smoker; 76 % adenocarcinoma; and 25 % NSCLCmut+. While 41 patients (38 %) had subsequent brain-only progressive disease (PD), 22 (20 %) developed extracranial metastases. A higher proportion of NSCLCmut+ (vs -wt) subsequently progressed outside the brain (37 % vs 15 %, p = 0.03). Median time-to-first-extracranial-metastases was 8.5 (NSCLCmut+) vs 21.0 months (NSCLCwt; p = 0.23).With 17.7 months median follow-up, median-OS was 15.9 months [95%CI: 11.5-21.3; all patients]; 12.3 [7.4-18.4; NSCLCwt] and 38.9 [21.3-not reached (NR); NSCLCmut+] (p = 0.09). In 33 of 80 patients with de novo BOM, the primary tumor was treated with surgery or radiotherapy. In patients with NSCLCwt, there was no OS benefit associated with local lung tumor treatment (p = 0.68), whereas in NSCLCmut + pts, local lung tumor treatment correlated with greater OS (median-OS NR vs 21.5 months; p = 0.05). Conclusion: In patients with NSCLCwt with BOM, we observed a -predominant pattern of brain-only secondary progression, however patients with NSCLCmut + more often progressed extracranially. In patients with NSCLCmut+ and BOM, definitive primary tumor treatment correlated with improved survival.
RESUMO
In advanced non-squamous non-small-cell lung cancer (NSCLC), routine testing with next-generation sequencing (NGS) is recommended to identify actionable genomic alterations (AGAs). The therapeutic implications of repeated NGS testing on synchronous and metachronous tumors are unclear. Between February 2017 and October 2020, NSCLC samples from a single institution were reflex-tested using a targeted 15-gene NGS panel (TruSight Tumor 15, Illumina). Thirty-eight patients were identified with multiple NGS results from 82 samples: 11% were from single unifocal, 51% were from synchronous, and 38% were from metachronous tumors. Changes in EGFR, KRAS, PI3KCA, and TP53 variants were found in 22 patients' samples (58%). No changes were seen with longitudinal testing of multiple samples from single unifocal tumors, while changes were observed in 60% of synchronous and 71% of metachronous tumors. Of these, 26% of patients had AGA differences between samples. Acknowledging the limited sample size, a significant difference in overall survival was observed between synchronous separate primaries and metastasis. Repeat NGS testing of synchronous and metachronous NSCLC tumors may identify differing variants in >50% of patients. These changes may reflect separate primary lung carcinomas, tumor heterogeneity among intrapulmonary metastases, and clonal evolution. NGS testing of multiple tumors may enhance the identification of therapeutic targets for treatment decisions.

Lorlatinib has been FDA-approved as a systemic therapy for ALK/ROS1-positive non-small cell lung cancer (NSCLC) patients. However, it has been associated with an increased frequency of neurocognitive adverse events (NAEs). Therefore, we conducted a systematic review and meta-analysis to assess the NAEs related to lorlatinib therapy in NSCLC patients. PubMed, Scopus, the Cochrane Library, and prominent conference proceedings were searched for eligible studies of lorlatinib in NSCLC patients. NAEs included cognitive, mood, speech, and psychotic effects. A total of 1147 patients from 12 studies were included; 62% had brain metastases. A pooled analysis of NAEs showed frequencies of cognitive effects of 14.57% (95% CI, 8.37 to 24.14, I2 = 84%), mood effects of 11.17% (95% CI, 5.93 to 20.07, I2 = 84%), speech effects of 7.24% (95% CI, 3.39 to 15.20, I2 = 72%), and psychotic effects of 4.97% (95% CI, 3.27 to 7.49, I2 = 21%). Clinical trials reported a significantly higher frequency of mood effects than was indicated by real-world data. These results highlight the importance of educating patients and healthcare professionals about lorlatinib-related NAEs for early detection and management to improve NSCLC patients' quality of life.
RESUMO
PURPOSE: Phase III studies of intravenous amivantamab demonstrated efficacy across epidermal growth factor receptor (EGFR)-mutated advanced non-small cell lung cancer (NSCLC). A subcutaneous formulation could improve tolerability and reduce administration time while maintaining efficacy. PATIENTS AND METHODS: Patients with EGFR-mutated advanced NSCLC who progressed after osimertinib and platinum-based chemotherapy were randomly assigned 1:1 to receive subcutaneous or intravenous amivantamab, both combined with lazertinib. Coprimary pharmacokinetic noninferiority end points were trough concentrations (Ctrough; on cycle-2-day-1 or cycle-4-day-1) and cycle-2 area under the curve (AUCD1-D15). Key secondary end points were objective response rate (ORR) and progression-free survival (PFS). Overall survival (OS) was a predefined exploratory end point. RESULTS: Overall, 418 patients underwent random assignment (subcutaneous group, n = 206; intravenous group, n = 212). Geometric mean ratios of Ctrough for subcutaneous to intravenous amivantamab were 1.15 (90% CI, 1.04 to 1.26) at cycle-2-day-1 and 1.42 (90% CI, 1.27 to 1.61) at cycle-4-day-1; the cycle-2 AUCD1-D15 was 1.03 (90% CI, 0.98 to 1.09). ORR was 30% in the subcutaneous and 33% in the intravenous group; median PFS was 6.1 and 4.3 months, respectively. OS was significantly longer in the subcutaneous versus intravenous group (hazard ratio for death, 0.62; 95% CI, 0.42 to 0.92; nominal P = .02). Fewer patients in the subcutaneous group experienced infusion-related reactions (IRRs; 13% v 66%) and venous thromboembolism (9% v 14%) versus the intravenous group. Median administration time for the first infusion was reduced to 4.8 minutes (range, 0-18) for subcutaneous amivantamab and to 5 hours (range, 0.2-9.9) for intravenous amivantamab. During cycle-1-day-1, 85% and 52% of patients in the subcutaneous and intravenous groups, respectively, considered treatment convenient; the end-of-treatment rates were 85% and 35%, respectively. CONCLUSION: Subcutaneous amivantamab-lazertinib demonstrated noninferiority to intravenous amivantamab-lazertinib, offering a consistent safety profile with reduced IRRs, increased convenience, and prolonged survival.

BACKGROUND: The 2018 ASCO pleural mesothelioma (PM) treatment guideline states that "a trial of expectant observation may be offered" in patients with asymptomatic inoperable epithelioid mesothelioma with low disease burden. The aim of our analysis was to evaluate clinical characteristics and outcomes in PM-patients managed with initial observation and deferred treatment initiation. METHODS: We retrospectively collected clinicodemograhic and outcome data of patients with inoperable PM. Patients were assigned to 2 treatment decision groups: decision to start immediate systemic treatment (Immediate Treatment Group) versus observation and deferring treatment (Deferred Treatment group). RESULTS: Of 222 patients with advanced PM, systemic treatment was started immediately in the majority of patients (189, 85%; immediate group); treatment was deferred in 33 (15%) patients (deferred group); systemic therapy was chemotherapy-based in 91% and 79% respectively. Patients in the deferred group were older (70 vs 67 years, p = .05), less likely to have stage IV disease (28% vs. 51%, p = .08) and more often had epithelioid histology (90% vs. 70%, p = .03). Nineteen patients (58%) in the deferred group eventually received treatment. With a median follow-up time of 10.9 months median overall survival (OS) in the entire cohort was 12.4 months and was significantly longer in the deferred group (20.6 months vs. 11.5 months, p = .02). No difference in median progression-free survival (PFS) in first-line treatment between groups was seen (5.4 and 5.3 months). CONCLUSION: This real-world analysis suggests that deferral of systemic therapy and close observation may not impact OS or physician-assessed PFS in selected PM-patients.

Real-world evidence for patients with advanced EGFR-mutated non-small cell lung cancer (NSCLC) in Canada is limited. This study's objective was to use previously validated DARWENTM artificial intelligence (AI) to extract data from electronic heath records of patients with non-squamous NSCLC at University Health Network (UHN) to describe EGFR mutation prevalence, treatment patterns, and outcomes. Of 2154 patients with NSCLC, 613 had advanced disease. Of these, 136 (22%) had common sensitizing EGFR mutations (cEGFRm; ex19del, L858R), 8 (1%) had exon 20 insertions (ex20ins), and 338 (55%) had EGFR wild type. One-year overall survival (OS) (95% CI) for patients with cEGFRm, ex20ins, and EGFR wild type tumours was 88% (83, 94), 100% (100, 100), and 59% (53, 65), respectively. In total, 38% patients with ex20ins received experimental ex20ins targeting treatment as their first-line therapy. A total of 57 patients (36%) with cEGFRm received osimertinib as their first-line treatment, and 61 (39%) received it as their second-line treatment. One-year OS (95% CI) following the discontinuation of osimertinib was 35% (17, 75) post-first-line and 20% (9, 44) post-second-line. In this real-world AI-generated dataset, survival post-osimertinib was poor in patients with cEGFR mutations. Patients with ex20ins in this cohort had improved outcomes, possibly due to ex20ins targeting treatment, highlighting the need for more effective treatments for patients with advanced EGFRm NSCLC.

MET exon 14 skipping mutation has emerged as a new oncogenic driver in NSCLC with available targeted therapies, including Food and Drug Administration-approved inhibitors capmatinib and tepotinib. Potential resistance mechanisms are beginning to be described and include several on-target and off-target mutations. Here, we report an emergent secondary RET fusion in a patient with a primary MET exon 14 skipping mutation that progressed on capmatinib after the initial response. Subsequently, this patient received both a RET inhibitor (selpercatinib) followed by another MET-targeted treatment (tepotinib) without clinical benefit. Thereafter, cabozantinib, a multikinase inhibitor with activity against RET and MET was started with a rapid clinical and radiologic benefit.

Introduction: Liquid biopsy is recommended to diagnose molecular resistance to targeted therapy in patients with lung cancer. Nevertheless, not all jurisdictions provide funding and patient access. We report patients' perceived value of liquid biopsy in targeted therapy resistance. Methods: Canadian patients participating in a national EGFR T790M liquid biopsy validation study completed structured interviews measuring perceived value and willingness-to-pay for plasma circulating tumor DNA testing as an alternative to tumor biopsy using open-ended and iterative bidding approaches. Results: A total of 60 patients with advanced lung cancer participated with a median age of 64 years (range: 31-87 y); 69% were Asian and 45% female. All had received prior EGFR tyrosine kinase inhibitor; 17% also received chemotherapy. All patients preferred to have plasma testing over repeat tumor biopsy. In the context of the Canadian publicly funded system, patients estimated that a median of 300 (interquartile range: 150-800) Canadian dollars was a reasonable price to pay for liquid biopsy. Patients were personally willing to pay a median 100 (interquartile range: 33-350) Canadian dollars. Conclusions: In a system that covers the cost of standard diagnostic tests, patients with lung cancer indicated high willingness-to-pay out-of-pocket for liquid biopsy in the setting of acquired targeted therapy resistance. Patients have high perceived value of plasma genotyping and prefer it to repeat tumor biopsy.
RESUMO
Aim: We assessed relative efficacy and safety of amivantamab versus mobocertinib in patients with non-small-cell lung cancer with EGFR exon 20 insertion (exon20ins) mutations who progressed on prior platinum-based chemotherapy. Materials & methods: This matching-adjusted indirect comparison used patient-level data from CHRYSALIS (NCT02609776) and aggregate data from a mobocertinib trial (NCT02716116) to match populations on all clinically relevant confounders. Results: While both agents had similar efficacy for time-to-event outcomes, objective response rate was significantly higher for amivantamab. 15 of 23 any-grade treatment-related adverse events reported for mobocertinib were significantly less common for amivantamab versus only two for mobocertinib. Conclusion: Results suggest that amivantamab has an improved response rate with similar survival and a more favorable safety profile versus mobocertinib in EGFR exon20ins non-small-cell lung cancer.

INTRODUCTION: The aim of this systematic review was to summarize the current literature on wearable technologies in oncology patients for the purpose of prognostication, treatment monitoring, and rehabilitation planning. METHODS: A search was conducted in Medline ALL, Cochrane Central Register of Controlled Trials, Embase, Emcare, CINAHL, Scopus, and Web of Science, up until February 2022. Articles were included if they reported on consumer grade and/or non-commercial wearable devices in the setting of either prognostication, treatment monitoring or rehabilitation. RESULTS: We found 199 studies reporting on 18 513 patients suitable for inclusion. One hundred and eleven studies used wearable device data primarily for the purposes of rehabilitation, 68 for treatment monitoring, and 20 for prognostication. The most commonly-reported brands of wearable devices were ActiGraph (71 studies; 36%), Fitbit (37 studies; 19%), Garmin (13 studies; 7%), and ActivPAL (11 studies; 6%). Daily minutes of physical activity were measured in 121 studies (61%), and daily step counts were measured in 93 studies (47%). Adherence was reported in 86 studies, and ranged from 40% to 100%; of these, 63 (74%) reported adherence in excess of 80%. CONCLUSION: Wearable devices may provide valuable data for the purposes of treatment monitoring, prognostication, and rehabilitation. Future studies should investigate live-time monitoring of collected data, which may facilitate directed interventions.

Health-related quality of life (HRQoL) is an important consideration in cancer clinical research, which can be substantially influenced by cancer treatment procedures and medications. The treatment landscape for early-stage (stage I-III) non-small cell lung cancer (NSCLC) is rapidly evolving. In this light, it is important to evaluate the most suitable instruments for HRQoL assessment and timing. Given there is often a requirement for patients with early-stage disease to receive long-term treatment to reduce the risk of disease recurrence after surgery, maintenance or improvement in HRQoL is an important goal of both neoadjuvant and adjuvant treatments. Key challenges with assessing HRQoL relate to the suitability of existing instruments to measure relevant treatment-related adverse effects, consistency in HRQoL assessment approach between similar studies, gaps in data collection and reporting, and interpretation of longitudinal data. Frequent assessments during and after treatment are warranted to capture the true impact of treatment and disease progression on HRQoL, and changes in the relative importance of these factors over time. There is scope for improving existing HRQoL approaches, including ease of use and integration of digital tools to facilitate analysis and interpretation, to enhance the experience of both patients and healthcare professionals. In this narrative review, we discuss key considerations for HRQoL assessment and evaluate the tools currently available to measure HRQoL in NSCLC, many of which were designed with advanced disease in mind. We focus on the key challenges of measuring HRQoL for the specific needs of patients with early-stage disease, and consider future perspectives, to determine the most appropriate HRQoL instruments and analysis methods to use in early-stage NSCLC clinical trials.1.

BACKGROUND: Multidisciplinary cancer conferences consist of regular meetings between diverse specialists working together to share clinical decision making in cancer care. The aim of this study was to systematically review and meta-analyze the effect of multidisciplinary cancer conference intervention on the overall survival of patients with cancer. METHODS: A systematic literature search was conducted on Ovid MEDLINE, EMBASE, and the Cochrane Controlled Register of Trials for studies published up to July 2023. Studies reporting on the impact of multidisciplinary cancer conferences on patient overall survival were included. A standard random-effects model with the inverse variance-weighted approach was used to estimate the pooled hazard ratio of mortality (multidisciplinary cancer conference vs non-multidisciplinary cancer conference) across studies, and the heterogeneity was assessed by I2. Publication bias was examined using funnel plots and the Egger test. RESULTS: A total of 134â287 patients with cancer from 59 studies were included in our analysis, with 48â467 managed by multidisciplinary cancer conferences and 85â820 in the control arm. Across all cancer types, patients managed by multidisciplinary cancer conferences had an increased overall survival compared with control patients (hazard ratio = 0.67, 95% confidence interval = 0.62 to 0.71, I2 = 84%). Median survival time was 30.2 months in the multidisciplinary cancer conference group and 19.0 months in the control group. In subgroup analysis, a positive effect of the multidisciplinary cancer conference intervention on overall survival was found in breast, colorectal, esophageal, hematologic, hepatocellular, lung, pancreatic, and head and neck cancer. CONCLUSIONS: Overall, our meta-analysis found a significant positive effect of multidisciplinary cancer conferences compared with controls. Further studies are needed to establish nuanced guidelines when optimizing multidisciplinary cancer conference integration for treating diverse patient populations.
