RESUMO
OBJECTIVE: To provide a nationwide description of postoperative outcomes and analysis of prognostic factors following adrenalectomy for metastases. SUMMARY BACKGROUND DATA: Adrenal glands are a common site of metastases in many malignancies. Diagnosisof adrenal metastases is on the rise, leading to an increasing number of patient candidates for surgery without consensual management. METHODS: We conducted a population-based study between January 2012 and December 2022 using the French national health data system (SNDS) and the Eurocrine® registry (NCT03410394). The first database exhaustively covers all procedures carried out in France, while the second provides more clinical information on procedures and tumor characteristics, based on the experience of 11 specialized centers. RESULTS: From the SNDS, we extracted 2,515 patients who underwent adrenalectomy for secondary malignancy and 307 from the Eurocrine® database. The most common primary malignancies were lung cancer (n=1,203, 47.8%) and renal cancer (n=555, 22.1%). One-year survival was 84.3% (n=2,120). Thirty-day mortality and morbidity rates were, respectively, 1.3% (n=32) and 29.9% (n=753, including planned ICU stays). Radiotherapy within the year before adrenalectomy was significantly associated with higher 30-day major complication rates (P=0.039). In the Eurocrine® database, the proportion of laparoscopic procedures reached 85.3% without impairing resection completeness (R0: 92.9%). Factors associated with poor overall survival were presence of extra-adrenal metastases (HR=0.64; P=0.031) and incomplete resection (≥R1; HR=0.41; P=0.015). CONCLUSION: The number of patients who can receive local treatment for adrenal metastases is rising, and adrenalectomy is more often minimally invasive and has a low morbidity rate. Subsequent research should evaluate which patients would benefit from adrenal surgery.
RESUMO
Cholangiocarcinoma is the second most common liver cancer after hepatocellular carcinoma. In case of metastatic or unresectable disease, the recommended first-line treatment is gemcitabine-based doublet, most commonly gemcitabine and cisplatin. There is no standard treatment for further lines. MET fusions are rare alterations described in many cancers. The efficacy of specific MET inhibitors is poorly studied. We present the case of a patient with chemotherapy-refractory metastatic cholangiocarcinoma harboring a CAPZA-2-MET fusion along with MET amplification who dramatically responded to capmatinib, a specific MET tyrosine kinase inhibitor.

BACKGROUND: A splice-site mutation that results in a loss of transcription of exon 14 in the oncogenic driver MET occurs in 3 to 4% of patients with non-small-cell lung cancer (NSCLC). We evaluated the efficacy and safety of tepotinib, a highly selective MET inhibitor, in this patient population. METHODS: In this open-label, phase 2 study, we administered tepotinib (at a dose of 500 mg) once daily in patients with advanced or metastatic NSCLC with a confirmed MET exon 14 skipping mutation. The primary end point was the objective response by independent review among patients who had undergone at least 9 months of follow-up. The response was also analyzed according to whether the presence of a MET exon 14 skipping mutation was detected on liquid biopsy or tissue biopsy. RESULTS: As of January 1, 2020, a total of 152 patients had received tepotinib, and 99 patients had been followed for at least 9 months. The response rate by independent review was 46% (95% confidence interval [CI], 36 to 57), with a median duration of response of 11.1 months (95% CI, 7.2 to could not be estimated) in the combined-biopsy group. The response rate was 48% (95% CI, 36 to 61) among 66 patients in the liquid-biopsy group and 50% (95% CI, 37 to 63) among 60 patients in the tissue-biopsy group; 27 patients had positive results according to both methods. The investigator-assessed response rate was 56% (95% CI, 45 to 66) and was similar regardless of the previous therapy received for advanced or metastatic disease. Adverse events of grade 3 or higher that were considered by investigators to be related to tepotinib therapy were reported in 28% of the patients, including peripheral edema in 7%. Adverse events led to permanent discontinuation of tepotinib in 11% of the patients. A molecular response, as measured in circulating free DNA, was observed in 67% of the patients with matched liquid-biopsy samples at baseline and during treatment. CONCLUSIONS: Among patients with advanced NSCLC with a confirmed MET exon 14 skipping mutation, the use of tepotinib was associated with a partial response in approximately half the patients. Peripheral edema was the main toxic effect of grade 3 or higher. (Funded by Merck [Darmstadt, Germany]; VISION ClinicalTrials.gov number, NCT02864992.).

Background Active endothelial cell proliferation occurs at the tumor edge, known as the invading-tumor front. This study focused on perfusion analysis of non-small cell lung cancers. Purpose To analyze dual-phase, dual-energy CT perfusion according to the degree of tumor hypoxia. Materials and Methods This prospective study was performed 2016-2017. A two-phase dual-energy CT protocol was obtained for consecutive participants with operable non-small cell lung cancer. The first pass and delayed iodine concentration within the tumor and normalized iodine uptake, corresponding to the iodine concentration within the tumor normalized to iodine concentration within the aorta, were calculated for the entire tumor and within three peripheral layers automatically segmented (ie, 2-mm-thick concentric subvolumes). The expression of the membranous carbonic anhydrase (mCA) IX, a marker of tumor hypoxia, was assessed in tumor specimens. Comparative analyses according to the histologic subtypes, type of resected tumors, and mCA IX expression were performed. Results There were 33 mCA IX-positive tumors and 16 mCA IX-negative tumors. In the entire tumor, the mean normalized iodine uptake was higher on delayed than on first-pass acquisitions (0.35 ± 0.17 vs 0.13 ± 0.15, respectively; P < .001). A single layer, located at the edge of the tumor, showed higher values of the iodine concentration (median, 0.53 mg/mL vs 0.21 mg/mL, respectively; P = .03) and normalized iodine uptake (0.04 vs 0.02, respectively; P = .03) at first pass in mCA IX-positive versus mCA IX-negative tumors. Within this layer, a functional profile of neovascularization was found in 23 of 33 (70%) of mCA IX-positive tumors, and the median mCA IX score of these tumors was higher than in tumors with a nonfunctional profile of neovascularization (median mCA IX score, 20 vs 2, respectively; P = .03). Conclusion A two-phase dual-energy CT examination depicted higher perfusion between the tumor edge and lung parenchyma in hypoxic tumors. © RSNA, 2021 Online supplemental material is available for this article.

PURPOSE: The objectives of this study were to compare the unmet supportive care needs (SCN) of caregivers and describe the 10 most frequent of them according to various cancer settings: phase of cancer care pathway (i.e., treatment vs. follow-up), cancer site (i.e., breast, digestive, or lung cancer), and cancer status (i.e., metastatic vs. non-metastatic). METHODS: Participants completed a self-reported questionnaire to assess their unmet SCN (SCNS-P&C). According to their cancer settings, non-parametric ANOVA or Mann-Whitney tests were performed to compare the SCNS-P&C scores. The prevalence of caregivers with unmet SCN was described using percentages. RESULTS: Among 583 participants, 516 caregivers (88.5%) completed the SCNS-P&C questionnaire. Most patients had digestive (47.3%), non-metastatic cancer (67.6%) and were recruited during the follow-up phase (56.2%). The results revealed no significant difference in SCNS-P&C scores according to cancer settings except for caregivers of patients with metastatic cancer, who reported more unmet SCN related to health care service and information needs. The more qualitative item per item analysis seems to indicate the existence of five frequently unsatisfied SCN across situations, especially concerns about the recurrence and reduction of stress in patients, with variable ranking among the most unmet SCN. CONCLUSION: Although there was no significant difference in unmet SCN scores between medical settings, examining the prevalence of unmet SCN helps identify the issues to focus on when supporting caregivers and developing dedicated consultations or interventions for them.

Introduction TAS-114 is a potent inhibitor of deoxyuridine triphosphatase, which is a gatekeeper protein preventing uracil and 5-fluorouracil (5-FU) misincorporation into DNA. TAS-114 has been suggested to enhance the antitumor activity of 5-FU. This randomized, phase 2 study investigated TAS-114 plus S-1 (TAS-114/S-1) vs. S-1 in non-small-cell lung cancer (NSCLC) patients. Methods Patients with advanced NSCLC, previously treated with ≥ 2 regimens, were randomized 1:1 to receive TAS-114 (400 mg)/S-1 (30 mg/m2) or S-1 (30 mg/m2). Progression-free survival (PFS, independent central review) was the primary endpoint. Secondary endpoints included disease control rate (DCR), overall survival (OS), overall response rate (ORR), and safety. Results In total, 127 patients received treatment. Median PFS was 3.65 and 4.17 months in the TAS-114/S-1 and S-1 groups, respectively (hazard ratio [HR] 1.16, 95% confidence interval [CI] 0.71-1.88; P = 0.2744). DCR was similar between groups (TAS-114/S-1 80.3%, S-1 75.9%) and median OS was 7.92 and 9.82 months for the TAS-114/S-1 and S-1 groups, respectively (HR 1.31, 95% CI 0.80-2.14; P = 0.1431). The ORR was higher in the TAS-114/S-1 group than the S-1 group (19.7% vs. 10.3%), and more patients with tumor shrinkage were observed in the TAS-114/S-1 group. Incidence rates of anemia, skin toxicities, and Grade ≥ 3 treatment-related adverse events were higher in the TAS-114/S-1 group compared with the monotherapy group. Conclusions Although the TAS-114/S-1 combination improved the response rate, this did not translate into improvements in PFS. Clinical Trial Registration No. NCT02855125 (ClinicalTrials.gov) registered on 4 August 2016.

BACKGROUND: The efficacy of ceritinib in patients with untreated anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC) is not known. We assessed the efficacy and safety of ceritinib versus platinum-based chemotherapy in these patients. METHODS: This randomised, open-label, phase 3 study in untreated patients with stage IIIB/IV ALK-rearranged non-squamous NSCLC was done in 134 centres across 28 countries. Eligible patients were assigned via interactive response technology to oral ceritinib 750 mg/day or platinum-based chemotherapy ([cisplatin 75 mg/m2 or carboplatin AUC 5-6 plus pemetrexed 500 mg/m2] every 3 weeks for four cycles followed by maintenance pemetrexed); randomisation was stratified by World Health Organization performance status (0 vs 1-2), previous neoadjuvant or adjuvant chemotherapy, and presence of brain metastases as per investigator's assessment at screening. Investigators and patients were not masked to treatment assignment. The primary endpoint was blinded independent review committee assessed progression-free survival, based on all randomly assigned patients (the full analysis set). Efficacy analyses were done based on the full analysis set. All safety analyses were done based on the safety set, which included all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT01828099. FINDINGS: Between Aug 19, 2013, and May 11, 2015, 376 patients were randomly assigned to ceritinib (n=189) or chemotherapy (n=187). Median progression-free survival (as assessed by blinded independent review committee) was 16·6 months (95% CI 12·6-27·2) in the ceritinib group and 8·1 months (5·8-11·1) in the chemotherapy group (hazard ratio 0·55 [95% CI 0·42-0·73]; p<0·00001). The most common adverse events were diarrhoea (in 160 [85%] of 189 patients), nausea (130 [69%]), vomiting (125 [66%]), and an increase in alanine aminotransferase (114 [60%]) in the ceritinib group and nausea (in 97 [55%] of 175 patients), vomiting (63 [36%]), and anaemia (62 [35%]) in the chemotherapy group. INTERPRETATION: First-line ceritinib showed a statistically significant and clinically meaningful improvement in progression-free survival versus chemotherapy in patients with advanced ALK-rearranged NSCLC.

BACKGROUND: Patients with advanced lung cancer (LC) or malignant pleural mesothelioma (MPM) exhibit limitation of exercise capacities and alteration of quality of life (QoL) induced by cancer and its treatment. Few studies assessed pulmonary rehabilitation (PR) in these chemotherapy-treated patients, and none evaluated a home-based PR program. METHODS: In this prospective uncontrolled observational pilot study, patients treated by chemotherapy for LC or MPM were screened for a home-based PR program combining exercise training with global cares including therapeutic education and psychosocial management. Feasibility and safety were evaluated by attendance and adherence to PR program. Various exercise tolerance tests, including 6-min walk test (6MWT) and 6-min stepper test (6MST), were performed before and after PR associated with, QoL and psychological assessment (VSRQ and HAD, respectively). RESULTS: 243 patients were considered eligible but only 71 (60.6 ± 8.8 years) started a PR and 47 completed the program. Refusals to participate were mostly related to lack of motivation whereas withdrawals to PR were related to cancer-related medical issues. No adverse event related to PR was observed. Baseline 6MWT distance was associated with performance status (r = - 0.45, p = 0.001) and mMRC dyspnea scale (r = - 0.49, p < 0.001) but not with lung cancer stage. Post-PR reassessment showed 6MWT stability and 6MST improvement in patients who completed the program. Daily physical activity (p = 0.007) and anxiety (p = 0.02) scores were significantly improved. CONCLUSIONS: Home-based PR was feasible and safe in patients with advanced LC or MPM. Exercise capacities stability in patients who completed the PR program suggests that PR might be beneficial. Further studies are warranted to confirm and to improve the potential value of PR in these patients.

BACKGROUND: The general population is nowadays well aware that tobacco smoking dramatically increases the risk of developing lung cancer. We hypothesized that a personal history of smoking and the level of nicotine dependence in current smokers may affect the perception of this risk among healthy individuals. METHODS: The fourth French nationwide observational survey, EDIFICE 4, was conducted by telephone among a representative sample of individuals (N = 1602) aged between 40 and 75 years. Interviewees were asked about their smoking habits, perception of the risk of lung cancer, and nicotine dependence (Fagerström test). RESULTS: Regardless of their smoking status or level of nicotine dependence, the majority (96%) of our study population (N = 1463) acknowledged that tobacco smoking is a major risk factor for lung cancer. For 34% of all respondents, smoking ≤ 10 cigarettes per day does not carry any risk of lung cancer. Only half the current smokers considered themselves to be at higher risk of lung cancer than the average-risk population. The majority of current cigarette smokers with a nicotine dependence considered themselves to be at higher risk for lung cancer while only 37% of non-nicotine-dependent individuals had the same perception (P < 0.01). Current smokers were more likely to consider a screening examination than former smokers and never-smokers. However, the intention to undergo screening was not significantly affected by the level of nicotine dependence. CONCLUSIONS: Awareness campaigns may first have to overcome misconceptions about light smoking and, secondly, to target specific populations (heavy smokers, those with a long history, highly dependent smokers).

OBJECTIVES: To determine the diagnostic accuracy of pharmacokinetic parameters measured by dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) in predicting the response of brain metastases to antineoplastic therapy in patients with lung cancer. METHODS: Forty-four consecutive patients with lung cancer, harbouring 123 newly diagnosed brain metastases prospectively underwent conventional 3-T MRI at baseline (within 1 month before treatment), during the early (7-10 weeks) and midterm (5-7 months) post-treatment period. An additional DCE MRI sequence was performed during baseline and early post-treatment MRI to evaluate baseline pharmacokinetic parameters (K trans, k ep, v e, v p) and their early variation (∆K trans, ∆k ep, ∆v e, ∆v p). The objective response was judged by the volume variation of each metastasis from baseline to midterm MRI. ROC curve analysis determined the best DCE MRI parameter to predict the objective response. RESULTS: Baseline DCE MRI parameters were not associated with the objective response. Early ∆K trans, ∆v e and ∆v p were significantly associated with the objective response (p = 0.02, p = 0.001 and p = 0.02, respectively). The best predictor of objective response was ∆v e with an area under the curve of 0.93 [95% CI = 0.87, 0.99]. CONCLUSIONS: DCE MRI and early ∆v e may be a useful tool to predict the objective response of brain metastases in patients with lung cancer. KEY POINTS: ⢠DCE MRI could predict the response of brain metastases from lung cancer ⢠∆v e was the best predictor of response ⢠DCE MRI could be used to individualize patients' follow-up.

Tumoral immune environment is a major component of cancer. Its composition and its organization represent a reproducible characteristic of tumors and a validated prognostic factor. In non-small cell lung cancer (NSCLC), cytotoxic T CD8+ lymphocyte density, associated with a Th1 environment and tertiary lymphoid structures impacts survival. Tumor cell-immune cell interaction is targeted by PD1/PD-L1 inhibitors. In advanced NSCLC, PD1/PD-L1 inhibitors are more effective than second-line chemotherapy. Pembrolizumab outperforms first-line chemotherapy in NSCLC strongly positive for PD-L1. PD1/PD-L1 inhibitors are currently tested in mesothelioma and thymic tumors. PD-L1 expression evaluated with immunochemistry is the most studied predictive biomarker of PD1/PD-L1 inhibitor efficacy. Tumor and immune cell expression of PD-L1 is still difficult to evaluate because of intra-tumoral heterogeneity and expression modulation by the microenvironment. Four commercial diagnostic antibodies are in development, with differences concerning recognized epitopes, methodology of evaluation of PD-L1 expression, positivity threshold, kit and platforms used. Clinical trials in NSCLC have shown that patients with tumors strongly positive for PD-L1 derived the best clinical benefit with PD1/PD-L1 inhibitors whereas clinical benefit is less common in tumors negative for PD-L1. PD-L1 expression is not a perfect biomarker since some PD-L1 negative NSCLC respond to PD1/PD-L1 inhibitors and some PD-L1 positive NSCLC do not. PD-L1 testing is likely to be implemented in daily practice for selection of advanced NSCLC that will be treated with pembrolizumab, underscoring the relevance of ongoing harmonization studies of the use of the different antibodies available for PD-L1 testing.

The clinical efficacy of epidermal growth factor receptor (EGFR) kinase inhibitors in EGFR-mutant non-small-cell lung cancer (NSCLC) is limited by the development of drug-resistance mutations, including the gatekeeper T790M mutation. Strategies targeting EGFR T790M with irreversible inhibitors have had limited success and are associated with toxicity due to concurrent inhibition of wild-type EGFR. All current EGFR inhibitors possess a structurally related quinazoline-based core scaffold and were identified as ATP-competitive inhibitors of wild-type EGFR. Here we identify a covalent pyrimidine EGFR inhibitor by screening an irreversible kinase inhibitor library specifically against EGFR T790M. These agents are 30- to 100-fold more potent against EGFR T790M, and up to 100-fold less potent against wild-type EGFR, than quinazoline-based EGFR inhibitors in vitro. They are also effective in murine models of lung cancer driven by EGFR T790M. Co-crystallization studies reveal a structural basis for the increased potency and mutant selectivity of these agents. These mutant-selective irreversible EGFR kinase inhibitors may be clinically more effective and better tolerated than quinazoline-based inhibitors. Our findings demonstrate that functional pharmacological screens against clinically important mutant kinases represent a powerful strategy to identify new classes of mutant-selective kinase inhibitors.

BACKGROUND: The management of stage III non-small-cell lung cancer (NSCLC) remains heterogeneous and complex, even after the approval of immune checkpoint inhibitors post-chemoradiotherapy (CRT). This observational study from France evaluated real-world practices in managing stage III NSCLC. METHODS: Between 2020 and 2022, we conducted a physician practice survey in 41 medical centers across France, and retrospectively analyzed aggregated information from 417 consecutive charts of patients with stage III NSCLC. We collected information on diagnostic and staging procedures, biomarker testing, surgical and non-surgical treatments, and follow-up. RESULTS: According to the physician survey, diagnostic workup of stage III NSCLC primarily relied on positron emission tomography/computed tomography and brain magnetic resonance imaging, performed for the majority of patients in 100 % and 78 % of centers, respectively. Of 417 patient charts, 414 were evaluable with 53 % of patients having stage IIIA disease, 37 % IIIB, and 10 % IIIC. The most common node involvement was N2 (59 %). Programmed death-ligand 1 testing was conducted for 98 % of patients. Invasive staging (mediastinoscopy or endobronchial ultrasound) was performed in 41 % of patients, of whom 83 % had N2 or N3 nodal involvement. Surgical resection was offered to 120 patients (29 %), with 85 % achieving R0 resection. In 292 charts of patients with unresectable stage III NSCLC, 190 patients (65 %) were offered CRT followed by consolidation immunotherapy. Within these patients, concurrent CRT was more frequently employed (52 %) than sequential CRT (13 %). CONCLUSIONS: Diagnostic procedures and treatment modalities in French medical centers generally align with clinical guidelines for stage III NSCLC, except for invasive staging that was less commonly performed than expected.

Gut microbiota impacts responses to immune checkpoint inhibitors (ICI). A high level of Faecalibacterium prausnitzii have been associated with a positive response to ICI in multiple cancer types. Here, based on fecal shotgun metagenomics data, we show in two independent cohorts of patients with non-small cell lung cancer and advanced melanoma that a high level of F. prausnitzii at baseline is positively associated with a better clinical response to ICI. In MCA205 tumor-bearing mice, administration of F. prausnitzii strain EXL01, already in clinical development for Inflammatory Bowel Disease, restores the anti-tumor response to ICI in the context of antibiotic-induced microbiota perturbation at clinical and tumor transcriptomics level. In vitro, EXL01 strain enhances T cell activation in the presence of ICI. Interestingly, oral administration of EXL01 strain did not induce any change in fecal microbiota diversity or composition, suggesting a direct effect on immune cells in the small intestine.

Although their efficacy has been well-established in Oncology, the use of platinum salts remains limited due to the occurrence of acute kidney injury (AKI). Caffeine has been suggested as a potential pathophysiological actor of platinum-salt-induced AKI, through its hemodynamic effects. This work aims to study the association between caffeine consumption and the risk of platinum-salt-induced AKI, based on both clinical and experimental data. The clinical study involved a single-center prospective cohort study including all consecutive thoracic cancer patients receiving a first-line platinum-salt (cisplatin or carboplatin) chemotherapy between January 2017 and December 2018. The association between daily caffeine consumption (assessed by a validated auto-questionnaire) and the risk of platinum-salt induced AKI or death was estimated by cause-specific Cox proportional hazards models adjusted for several known confounders. Cellular viability, relative renal NGAL expression and/or BUN levels were assessed in models of renal tubular cells and mice co-exposed to cisplatin and increasing doses of caffeine. Overall, 108 patients were included (mean age 61.7 years, 65% men, 80% tobacco users), among whom 34 (31.5%) experienced a platinum-salt-induced AKI (67% Grade 1) over a 6-month median follow-up. The group of high-caffeine consumption (≥386 mg/day) had a two-fold higher hazard of AKI (adjusted HR [95% CI], 2.19 [1.05; 4.57]), without any significant association with mortality. These results are consistent with experimental data confirming enhanced cisplatin-related nephrotoxicity in the presence of increasing doses of caffeine, in both in vitro and in vivo models. Overall, this study suggests a potentially deleterious effect of high doses of daily caffeine consumption on the risk of platinum-salt-related AKI, in both clinical and experimental settings.

There are no international guidelines for an appropriate and cost-effective follow-up for resected nonsmall cell lung cancer (NSCLC). We retrospectively reviewed the outcome of NSCLC patients after curative surgery. Follow-up included physical examination and chest radiography every 3 months, and chest computed tomography (CT) scan, bronchoscopy, abdominal ultrasound, brain CT scan and bone scan every 6 months for 3 years, then every year over the following 2 years. Prognostic factors and costs were analysed. Median overall survival following surgery for NSCLC in 162 patients was 38.5 months. Recurrence occurred in 85 (52.5%) patients including 41 (48%) symptomatic subjects. Disease-free survival was similar between patients with asymptomatic recurrence versus symptomatic patients (11.4 versus 12 months; p=0.41). Recurrence was detected by physical examination or chest radiography in 47 (55.3%) patients. Curative-intent therapy was provided in 18 (41%) out of 44 patients with asymptomatic recurrence and in four (10%) out of 41 symptomatic cases (p=0.001). Median overall survival from time of recurrence was higher in asymptomatic patients than in symptomatic patients (15.5 versus 7.2 months; p=0.001). The cost per year of life gained was USD32 700 (22 397). An extensive follow-up, with acceptable cost, may improve the outcome of patients with resected NSCLC through detection of asymptomatic recurrences; however, validation by prospective studies is required.

OBJECTIVES: To determine whether CT can depict early perfusion changes in lung cancer treated by anti-angiogenic drugs, allowing prediction of response. METHODS: Patients with non-small cell lung cancer, treated by conventional chemotherapy with (Group 1; n = 17) or without (Group 2; n = 23) anti-vascular endothelial growth factor (anti-VEGF) drug (bevacizumab) underwent CT perfusion before (TIME 0) and after 1 (TIME 1), 3 (TIME 2) and 6 (TIME 3) cycles of chemotherapy. The CT parameters evaluated included: (1) total tumour vascular volume (TVV) and total tumour extravascular flow (TEF); (2) RECIST (Response Evaluation Criteria in Solid Tumours) measurements. Tumour response was also assessed on the basis of the clinicians' overall evaluation. RESULTS: In Group 1, significant reduction in perfusion was identified between baseline and: (1) TIME 1 (TVV, P = 0.0395; TEF, P = 0.015); (2) TIME 2 (TVV, P = 0.0043; TEF, P < 0.0001); (3) TIME 3 (TVV, P = 0.0034; TEF, P = 0.0005) without any significant change in Group 2. In Group 1: (1) the reduction in TVV at TIME 1 was significantly higher in responders versus non-responders at TIME 2 according to RECIST (P = 0.0128) and overall clinicians' evaluation (P = 0.0079); (2) all responders at TIME 2 had a concurrent decrease in TVV and TEF at TIME 1. CONCLUSION: Perfusion CT demonstrates early changes in lung cancer vascularity under anti-angiogenic chemotherapy that may help predict therapeutic response. KEY POINTS: ⢠Perfusion CT has the potential of providing in vivo information about tumour vasculature. ⢠CT depicts early and specific perfusion changes in NSCLC under anti-angiogenic drugs. ⢠Specific therapeutic effects of anti-angiogenic drugs can be detected before tumour shrinkage. ⢠Early perfusion changes can help predict therapeutic response to anti-angiogenic treatment. ⢠Perfusion CT could be a non-invasive tool to monitor anti-angiogenic treatment.

INTRODUCTION: MET exon 14 (METex14) skipping is a rare oncogenic driver in non-small-cell lung cancer (NSCLC) for which targeted therapy with MET tyrosine kinase inhibitors (TKIs) was recently approved. Given the heterogeneity in published data of METex14 skipping NSCLC, we conducted a systematic literature review to evaluate its frequency, patient characteristics, and outcomes. METHODS: On June 13, 2022 we conducted a systematic literature review of publications and conference abstracts reporting frequency, patient characteristics, or outcomes of patients with METex14 skipping NSCLC. RESULTS: We included 139 studies reporting frequency or patient characteristics (350,997 patients), and 39 studies reporting clinical outcomes (3989 patients). Median METex14 skipping frequency was 2.0% in unselected patients with NSCLC, with minimal geographic variation. Median frequency was 2.4% in adenocarcinoma or nonsquamous subgroups, 12.0% in sarcomatoid, and 1.3% in squamous histology. Patients with METex14 skipping NSCLC were more likely to be elderly, have adenocarcinoma histology; there was no marked sex or smoking status distribution. In first line of treatment, median objective response rate ranged from 50.7% to 68.8% with targeted therapies (both values correspond to MET TKIs), was 33.3% with immunotherapy, and ranged from 23.1% to 27.0% with chemotherapy. CONCLUSIONS: Patients with METex14 skipping are more likely to have certain characteristics, but no patient subgroup can be ruled out; thus, it is crucial to test all patients with NSCLC to identify suitable candidates for MET inhibitor therapy. MET TKIs appeared to result in higher efficacy outcomes, although no direct comparison with chemotherapy or immunotherapy regimens was found.

Background: The optimal duration of immune checkpoint inhibitor (ICI) treatment for patients with advanced non-small cell lung cancer (NSCLC) remains to be determined. Treatment durations in cornerstone phase 3 clinical trials vary between a fixed 2-year duration and pursuit until disease progression. Clinical practices may thus differ according to the attending physician. Objectives: Here we provide real-world data about treatment decisions at 2 years, with subsequent clinical outcomes. Design and Methods: This multicentric observational study included patients with advanced NSCLC whose disease was controlled after 2 years of pembrolizumab or nivolumab. The primary outcome was the decision to discontinue ICI treatment or not, along with factors motivating this decision. Secondary outcomes included progression-free survival (PFS) (according to treatment continuation or not) and adverse events. Results: A total of 91 patients were included, of which 60 (66%) had been pre-treated. The programmed death-ligand 1 expression level was ⩾50% in 43 patients (47%). In 61 patients (67%), ICI was continued after 2 years of treatment. This decision was significantly associated with the care center (p < 0.001) but neither with the tumor response at 2 years, as evaluated by CT scan or PET scan, nor with clinical status, immune-related adverse events, or previous locally treated oligo-progressive disease under ICI. Two years after the 2-year decision, PFS was 68.5%, [95% confidence interval (CI) (53.3-88.0)] in the 'ICI discontinuation' group and 64.1% [95% CI (51.9-79.2)] in the 'ICI pursuit' group; hazard ratio for relapse was 1.14 [95% CI (0.54-2.30), p = 0.77]. The overall survival rate at 24 months after discontinuation was 89.2% [95% CI (78.4-100)] for the 'discontinuation' group and 93.1% [95% CI (85.8-100)] for the 'pursuit' group. Given insufficient power, overall survival could not be compared. Conclusion: The decision to continue ICI or not after 2 years of treatment depends mainly on the care center and does not seem to impact survival. Larger, randomized data sets are required to confirm this result.
RESUMO
INTRODUCTION: The existing literature shows a significant impact of cancer on caregivers' quality of life (QoL) and divergent results according to associated factors. To better understand the experience of cancer patients' caregivers, the present study aimed at comparing caregivers' QoL according to cancer care pathway and type of cancer, and at identifying the factors associated with their QoL. METHODS: Caregivers were included in the study either during chemotherapy or follow-up to assess their QoL (CARGOQoL), unmet supportive care needs (SCNS-P&C), and anxiety and depression levels (HADS). CARGOQoL scores were then compared using ANOVA or Mann-Whitney non-parametric tests (objective 1). Based on univariate analyses, a multivariate analysis of covariance or linear regression model was performed for each CARGOQoL dimension (objective 2). RESULTS: Among 583 participants (57.29% included during the follow-up phase), 523 completed the questionnaires. There was no effect of treatment phase and little effect of cancer site or disease stage on caregivers' QoL. Although significant factors associated with caregivers' QoL varied according to the dimensions assessed, the main associated factors were psychological experience (p < 0.05), satisfaction with the patient's care and supportive care needs (p < 0.01), and age of the patient or caregiver (p < 0.005). CONCLUSION: This study shows the necessity to support caregivers during both active treatment and follow-up. It highlights the crucial role of emotional distress, supportive care and age in caregivers' QoL, regardless of the patients' oncological status.
